Raw Blame History

3.1.0, 2010.06.03 (r2670)
o Default MySQL version now 5.1, having entered GA since 3.0.9.
o Lots of platform updates tracked, lots of warnings from newer
compilers squished. Most by me, some by Adrian Cornish.
o Added Query::insertfrom(), plus associated classes SQLStream,
NoTransactions, and the InsertPolicy hierarchy. Also adds
examples/ssqls6.cpp, which shows how to use this new feature.
Thanks for this feature go to Rick Gutleber, except for
RowCountInsertPolicy, by me.
o Added comparison operators to tiny_int<T>. Thanks for this patch
go to Edward Diener.
o Added SQLTypeAdapter::is_null(). This lets you retrieve a
nullable column from the DB, then re-insert a value from that
column back into the DB via a template query without explicit
checks for null-ness; it will do the right thing now.
o Added -f flags to lib/*.pl header file generating scripts to
allow overriding the default limit of 25 fields for tqueries
and SSQLSes without having to edit the file, as in previous
versions of MySQL++. Also added --with-field-limit option to
the configure script so you can give both -f options at once
during the build process. This latter is especially useful
for automated binary package builders.
o The file lib/querydef.h (generated by lib/querydef.pl) now
defines the MYSQLPP_TQUERY_MAX_PARAMETERS macro, giving the
maximum number of parameters the functions in the generated file
allow for template queries. Similarly, lib/ssqls.h (generated
by lib/ssqls.pl) defines MYSQLPP_SSQLS_MAX_MEMBERS.
o Added ConnectionPool::safe_grab(), which pings the grabbed
connection before returning it. If the ping fails, we remove
the dead connection from the pool and try again. This doesn't
eliminate the possibility of returning a dead connection;
there is no protection against race conditions. It is merely
a best-effort attempt.
o Added ConnectionPool::remove(Connection*), which removes a
connection from the pool.
o Added ConnectionPool::exchange(), which wraps remove()
and grab().
o Added a feature to Transaction, where it can send a SET
TRANSACTION ISOLATION LEVEL query before it starts the
transaction proper, affecting the isolation level and the scope
of that change.
o Added ScopedConnection class. Initial version by Joel Fielder,
lots of changes by me. Using it instead of explicit safe_grab()
and release() calls on the pool in examples/cpool.cpp.
o Added FieldNames::operator[](size_type) overloads. This is
necessary to correctly overload the base class versions inherited
from std::vector.
o FieldNames wasn't doing field-by-name matches case insentitively,
most likely since 3.0.0 when we changed it to derive from
std::vector. This caused SSQLS (at least) to be case sensitive.
Fixed this and renamed the stock.sdate field in the SSQLS
examples to stock.sDate to test this.
o Added Query::replace(iter, iter), on the model of existing
insert(iter, iter). Thanks for this patch go to David Walthour.
o Added Query::operator!(), overriding basic_ios version so that
"if (!query)" does the right thing. Fixes problem report in
thread http://lists.mysql.com/plusplus/8594
o Query copy ctor and assignment operator now perform deeper
copies, so you can pass Query objects around in certain ways
that used to cause crashes. Thanks for this patch go to Steven
Van Ingelgem.
o Defined *_null variants for every sql_* typedef, wrapping
all those earlier types in Null<>. All example programs now use
these types instead of explicit Null<>-wrapped types.
o Created a C++ command line parsing mechanism for the examples
today, and for programs coming in the future. It uses the
platform version of getopt() if available, substituting a
public-domain implementation that gets built into MySQL++
itself otherwise. It's documented in the refman -- see
the CommandLineBase class -- but it's in the newly created
mysqlpp::internal namespace, which means we don't promise any
sort of ABI or API stability for it. You're welcome to use it
in your own programs, but expect it to change without warning.
o Added a few missing MYSQLPP_EXPORTs to operator<<()s for stream
manipulators, to allow their use when MySQL++ is built as a DLL.
o Added backticks around table and column identifiers in all
code paths exercised by dtest. There are some others remaining,
particularly things like Row::field_list(). Thanks for this
patch go to Adrian Cornish.
o Added mysqlpp::NOW() which returns a value that, when inserted
into a SQL query, results in a call to SQL's NOW() function.
DateTime::now() -- added in 3.0.0 -- does the same thing,
but this is shorter and matches the SQL syntax.
o Calling DBDriver::disconnect() twice no longer calls
mysql_close() twice.
o Worked around a weakness on Windows that caused problems in code
with a connect(), disconnect(), connect() call pattern, when
also using a named pipe to connect to the DB. (There never
has been a problem with this on other platforms or with other
IPC mechanisms.)
o Initializing a SQLTypeAdapter with a floating-point value
equal to infinity or NaN results in SQL null if the type
is also nullable, or 0 otherwise. Previously, we got an
implementation-defined string, which could give invalid SQL,
or could give 0, a different value from NaN, infinity, or
SQL null. This does collapse the notions of NaN and infinity,
but the MySQL reference manual doesn't say how you're supposed
to preserve these differences.
o Removed the dependency of stadapter.h on sql_types.h, just to get
sql_tinyint*. #including tinyint.h instead, and using equivalent
types to what sql_types.h defines. This is necessary because
sql_types.h should be one of the last things included from
mysql++.h, so that it can define sql_* equivalents for everything
else in MySQL++, which means all those other things need to be
#included by that point.
o The "find MySQL++" autoconf macro (config/mysql++.m4) now
searches for the library in lib64 subdirectories everywhere it
also looks in lib. We did this for the C API finder macro way
back in MySQL++ 2.2.0, and only neglected to do it for this
macro because it's not used by MySQL++ itself, just provided
as a courtesy to MySQL++ users that also use autoconf.
o Also improved the "find C API" macro (config/mysql_loc.m4)
so it, too, is more useful in third-party projects.
o Moved private FieldNames::str_to_lwr() method out into its
own module, in the new mysqlpp::internal namespace, so other
modules can use it. Also added an overload for this new global
method taking std::string instead of char*.
o userman build process can now find FOP when installed from
the standard Ubuntu/Debian package repository.
o No longer generating refman.pdf. It's difficult to generate
properly on some platforms, and isn't all that useful anyway
compared to the HTML version, which builds properly everywhere.
o Dropped custom.h backwards-compatibility header. (Deprecated
over a year ago in MySQL++ 3.0.0.)
o Fixed a bad pointer access crash in Connection::set_option()
triggered when the option set call fails. Thanks for this
patch go to Kevin Regan.
o ReconnectOption behavior now knows about a fix in MySQL 5.1.6 and
newer that lets you set it either before the connection is up,
or after. If you try to set this option when MySQL++ is built
against earlier versions of the MySQL C API, it will refuse to
set the option because it knows the option will be reset when
the connection comes up.
o No longer trying to make the C API library read from a "my"
options file before connect. It does that by default, and
the file is supposed to be .my.cnf anyway.
o Reworked the load_jpeg example code for clarity, extracting
load_jpeg_file() routine as an implementation detail and
making that use the C++ stringstream "slurp into string" idiom
instead of allocating a C char buffer and copying that into
a std::string.
o Restored support for repeating query parameters. Apparently
you could say things like "stuff %0 morestuff %0" in v2.1,
but this was broken by initial 1-parameter fixes in v2.2.
This patch reportedly lets us have both things at once, and
improves handling of 1-parameter template queries in general.
Thanks for this patch go to Martin Gallwey.
o Added examples/tquery4.cpp based on test code and feedback
from Martin.
o Put Comparable class in namespace mysqlpp, where it should always
have been. Aside from being just plain wrong, it caused a
conflict with Boost if you used its Comparable class and hoist
them both into the global namespace. Thanks for this patch go
to Michael Radzewitz.
o Fixed all the known problems with the Xcode project files.
o Skeletal support for SSQLS v2. Doesn't do anything useful
yet, it just got caught up in the need to release 3.1 as-is.
o Various enhancements to the test suite.
o Many, many documentation enhancements.
3.0.9, 2009.02.04 (r2442)
o It is now possible to use Null<T> objects in const context.
o Query was emitting thousands separators when used in some
locales. Thanks for the fix go to Tomaž Šolc.
o Restored support for using Query::storein() with template
queries. Was mistakenly removed in the 3.0.0 development
process.
o GCC 4.4 build fixes. Thanks for this go to Remi Collet.
3.0.8, 2008.11.27 (r2432) The "Thanksgiving" release
o Fixed a VC++ build error introduced in 3.0.7 in the Sun CC fix.
o Fixed the Makefile we generate from Makefile.simple for the
devel RPM. The recent Bakefile upgrade changed the output so
our munger stopped munging.
o Changed all instances of "CREDITS" in header comments to
"CREDITS.txt".
o Brought ebuild file up to date with what Gentoo has been
using for 2.3.2.
3.0.7, 2008.11.21 (r2423)
o Fixed bug where initting a Query with a query string and then
appending more to it with operator <<() would start overwriting
the beginning of the buffer. Thanks for the fix go to Chris
Frey.
o Added String::empty(), to parallel std::string better.
o Added SQLTypeAdapter ctor for Null<String>, to allow SSQLS with
NULL BLOB columns. Thanks for this patch go to Russell Robinson.
o Passing on "throw exceptions" flag in Query::storein() to the
temporary Row objects it creates. (Should have done this
all along.)
o All MySQL++ classes with operator[]() and at() methods now
throw the new BadIndex exception on out of range indices now,
unconditionally. Before, it was a mishmash of MySQL++-specific
mechanisms, std::range_error, and unchecked access.
o Fixed some bugs in load_jpeg and cgi_jpeg examples that prevented
them from working correctly on Windows.
o Squished some warnings and incompatibilities that caused
difficulty with Solaris CC.
o Several minor fixes to allow building on Cygwin again.
o Dedicated VC++ 2008 support. (Not just a clone of VC++ 2005
project files in a different directory.)
o Lots of documentation improvements.
3.0.6, 2008.08.16 (r2350)
o Several fixes to allow thread-aware build on Solaris
o More improvements to search for Fink version of C API library.
o Various improvements to Windows installer (install.hta)
3.0.5, 2008.08.06 (r2332)
o Replaced install.bat with new install.hta, which has a GUI and a
lot of embeded logic for doing The Right Thing, which we couldn't
do in a dumb batch file.
o Several fixes to allow it to build on Solaris 10.
o Fixed a bug in comparison of Null<T> to T: wouldn't always give
the right result for one particular combination of argument
values and order of parameters to operator <(). It wouldn't
fail all the time, either; it depended on the way the system's
memory allocator dealt with newly allocated RAM. The bug was
discovered during the Solaris 10 porting effort, but it is not
a Solaris-specific bug.
o Split Linux-specific material out of README-Unix.txt into
README-Linux.txt, and created README-Solaris.txt.
o Shipping a vc2008 directory. Populated by bootstrap script with
copies of vc2005 files when those are newer, with the idea being
to update them by hand by running them through VC++2008 before
release.
o Several fixes to VS-only examples. They hadn't been updated to
track several of the changes in MySQL++ v3, so they wouldn't
build OOTB at all, crashed when you did get them building, and
emitted a lot of warnings during the build. Cleaned it all up.
o Autoconf now explicitly checks whether we need to link to zlib
to link to MySQL C API library. It used to be required, but
lately, MySQL has been shipping the library with zlib stuff
embedded, causing multiply defined symbol errors on some systems.
o configure script now looks in more locations for the MySQL C API
library, adding default locations for Fink and Solaris.
3.0.4, 2008.07.02 (r2303)
o Fixed a few bugs in SslOption that prevented it from actually
working. If you've been having SSL problems since upgrading
to MySQL++ v3, this is why! Thanks for these patches go to
Petteri Kiiskinen.
o Changed type of String's internal "size" typedefs so it'll
build without errors on 64-bit systems where these ints are
different sizes.
o Many user manual improvements.
3.0.3, 2008.05.11 (r2284)
o Fixed query well-formedness handling in Query::store() and use().
It was quietly eating these errors, confusing them with the
no-results case.
o Fixed examples/cpool.cpp to build without thread support.
o No longer hiding all stdint.h typedefs inside namespace mysqlpp.
o Fixed mysqlpp::String comparisons of empty strings against
nonempty strings; if the empty string was on the left hand side,
it would succeed because it was only comparing against characters
in the empty side, which matches everything. (Fixes bug 11588.)
3.0.2, 2008.04.13 (r2275)
o Increased float to string conversion precision from 7 to 9 and
double from 16 to 17 digits. Previous values weren't enough
near the maximum values that each can hold.
o Replaced Query's safe bool mechanism with an override of
basic_ios::operator void*() to avoid a conflict between the
two mechanisms. As the base class version isn't virtual,
this is arguably evil, but it should be harmless in typical use.
Besides, testing Query in bool context usually isn't the right
thing anyway: test the result set instead.
o Made ConnectionPool::grab() virtual.
o Overriding ConnectionPool::grab() and release() in
examples/cpool.cpp to show how to do connection-in-use count
limiting. Also, added a few more output indicator states to
allow one to better understand program flow.
3.0.1, 2008.03.23 (r2263)
o String objects can now be compared to mysqlpp::null directly.
o Added a template operator== and operator!= to String, syntactic
sugar for the existing String::compare() methods.
o String::compare() now returns 0 ("equal") when one of the
strings is an uninitialized String() (no refcounted buffer)
and the other is empty. It used to consider any initialized
string greater than an uninitted one. An uninitialized String
appears empty, though, so this was incorrect.
o Made Connection::thread_aware(), thread_start() and thread_end()
static methods, so they can be called before you create your
first connection. Ditto for DBDriver versions of these methods.
o Calling Connection::thread_start() and thread_end() in
examples/cpool.cpp, as appropriate. Above changes were necessary
to make this work sensibly.
o Made ConnectionPool::release() virtual, so your pool subclass can
override it.
o Added ConnectionPool::size(), so a subclass can know the current
number of extant connections.
o No longer single-quoting NOW() call generated for default
init of DateTime type when building queries from SSQLS objects
in Query::insert(), replace() and update(). The template query
and stream interfaces of Query treated NOW() correctly already.
o Fixed a bug that left SSQLS::table_override_ uninitted if
you used certain of the generated ctors or set() member
functions instead of others used by the examples. This could
cause a crash any time you caused SSQLS.table() to be called,
such as when passing the SSQLS to Query::insert().
o Minor memset bug fixed in test/uds.cpp. Patch by Dave Jones.
3.0.0, 2008.02.29 (r2236) The "Giant Leap Forward" release
THIS IS NOT A DROP-IN REPLACEMENT FOR MySQL++ v2.x!
You will have to recompile your program against this version
of the library, and you will almost certainly have to make code
changes as well. Please see these sections in the user manual
for information on migrating your code to this new version:
http://tangentsoft.net/mysql++/doc/html/userman/breakages.html#api-3.0.0
http://tangentsoft.net/mysql++/doc/html/userman/breakages.html#abi-3.0.0
o Added ConnectionPool class, primarily to let multithreaded
programs share a set of Connection objects safely in situations
where it isn't acceptable to have a Connection per thread.
o Created examples/cpool.cpp to demonstrate this new class.
o Added RefCountedPointer template, which provides automatic
memory management and data sharing. It's not intended
for use outside of MySQL++ itself, but it's the mechanism
behind everything below where reference counting is mentioned.
I created the initial version of it, but Jonathan Wakely almost
completely rebuilt it, and Joseph Artsimovich provided helpful
commentary and advice as well.
o Many improvements to Specialized SQL Structures (SSQLS):
- Renamed custom* to ssqls*. There's still a custom.h which
#includes ssqls.h for you, but it's only intended to ease
the transition to the new name. It will go away in a future
release, probably as soon as v3.1.
- SSQLSes are finally compatible with Null<>-wrapped types. This
feature is based loosely on the "Waba" patch posted to the
mailing list back in the v2.0 days, but extended to allow
Null<T> types for key fields. (The Waba patch only allowed
these types in non-key fields.)
- It's no longer necessary to define a different SSQLS for each
different field set you use in queries. That is to say,
you can define an SSQLS for an entire table and store just a
subset of the table in it now, with the other fields keeping
default values. Removed examples/custom6.cpp, as custom1.cpp
can now demonstrate the same thing, implicitly.
- An SSQLS's field order no longer has to match the order of
fields in the result set it is populated from.
- As a result of previous, removed sql_create_c_order_* macros;
they have no purpose now.
- Removed order parameters from sql_create_complete_*, which now
gives it the same functionality as sql_create_c_names_* so
removed the latter, too.
- Removed "basic" variants of SSQLS creation macros. They've
been unofficially deprecated by dint of being all but
undocumented and unexemplified for a very long time now.
- It's now possible to use mysqlpp::String, Date, DateTime, and
Time types in the key field positions in an SSQLS as they
now support the necessary comparison interfaces.
- If you use a floating-point data type in one of the key field
positions, it no longer uses exact comparison logic. Instead,
it now does [in]equality comparisons by testing whether the
difference between two floating-point values is less than a
configurable threshold defaulting to 0.00001.
- You can now use 'bool' type in an SSQLS.
- Renamed _table static member variable in each SSQLS to table_
and made it private. There are now public setter and getter
methods, table().
- Added per-instance table name overriding via instance_table()
setter. table() getter returns static version if this is not
set, so it's still a global setting by default.
o You can now use mysqlpp::null as a template query parameter to
get a SQL null.
o Replaced template ColData_Tmpl<T>:
- Used to have typedef ColData_Tmpl<std::string> MutableColData.
It was used only once within MySQL++ itself, and was never
documented as a class for end users. This one use within
the library was a crock, so we just replaced this use with
std::string and removed the typedef.
- This left just one use of ColData_Tmpl<T>, instantiating it
with the MySQL++ utility class const_string, basically a
clone of std::string with all the mutating features removed.
Folded the functionality of const_string into the template,
renamed the result to String, and deleted the const_string
class. It'd be a complete std::string replacement -- with
SQL-related enhancements -- if it were modifiable, but MySQL++
doesn't need it to be modifiable. Yet, it's still the closest
thing MySQL++ has to its own string type; thus the name.
- Replaced its internal buffer management with a much more
clever reference counted scheme. This shows its greatest
advantage in the return from Row::operator[](), which for
technical reasons must return by value, not by reference
as is more common. This lets you pass around Strings by
value while having the efficiency of reference semantics.
This can be important with large return values, like BLOBs.
- Converting String to numeric types (ints, floats...) uses a
new, cleaner system by Jonathan Wakely. Unless you were
abusing weaknesses in the old system, you won't see a
difference. It's just more robust and flexible.
o Redesigned SQLString:
- It used to derive from std::string, and while MySQL++'s
internals did use it in place of std::string, these places
didn't take advantage of the additional features offered
by SQLString. So, replaced all those uses with std::string.
- All the remaining uses are MySQL++ public interfaces that
need to be able to accept any of many different data types,
and we want that data to be automatically converted to a
SQL-compatible string form. Because it no longer has the
parentage to be a general-purpose string type and MySQL++ has
a new contender for that role (String), renamed SQLString to
SQLTypeAdapter to reflect its new, limited purpose. ("STA"
for short.)
- Since we don't have the std::string base class to manage the
string buffer any more, using the same reference counted
buffer mechanism as String. In addition to saving code by
not creating yet another buffer management mechanism, it means
objects of the two classes can share a buffer when you assign
one to the other or pass one to the other's copy ctor.
- Added many more conversion ctors.
- STA interfaces using the 'char' data type now treat them as
single-character strings instead of one-byte integers, as
does the Standard C++ Library.
- Added mysqlpp::tiny_int interfaces to STA to replace the
former char interfaces for those needing one-byte integers.
o As a result of the ColData -> String redesign, removed
Row::raw_*(). Before String copies were efficient, this
was helpful in accessing BLOB data efficiently. It was also
required back when ColData didn't deal correctly with embedded
null characters, but that reason is gone now, too.
o Row::operator[](const char*) no longer unconditionally throws the
BadFieldName exception when you ask for a field that doesn't
exist. It will still throw it if exceptions are enabled, but if
not, it'll just return an empty String. This was necessary to
make the SSQLS subset and field order independence features work.
o Similarly, Result::field_num() returns -1 when exceptions are
disabled and you ask for a field that doesn't exist.
o You can now use the OptionalExceptions mechanism to disable
exceptions on const MySQL++ objects.
o Redesigned query result classes:
- Instead of Result deriving from ResUse, the two derive from
a common base class -- ResultBase -- containing the bits that
are truly the same between them. Before, Result inherited
several methods that didn't really make sense for "store"
query result sets.
- Renamed Result to StoreQueryResult and ResUse to UseQueryResult
so it's clearer what each is for.
- Renamed ResNSel to SimpleResult.
- Made all SimpleResult data members private and hid them behind
const accessor functions of the same name.
- The result set classes all used to be friends of Connection
for various lame reasons. Since they are created by Query,
and Query has a good reason for a strong relationship with
Connection, moved Connection access out of each result set
class into the code in Query that creates that type of result
set object.
- StoreQueryResult now derives from vector<Row> in addition to
ResultBase; it used to merely emulate a vector of Rows, poorly.
It can now dispose of the MYSQL_RESULT at the end of object
construction, because it creates all the Row objects up front
instead of on the fly. And as a result of *that*, operator[]
returns by reference instead of by value, operator -> works
correctly on iterators, all STL algorithms work, etc., etc.
- IMPORTANT COMPATIBILITY BREAK: because we used fetch_row()
stuff in Result previously, it was okay to index past the
end of the result set: you'd just get a falsy Row when you
did this, just as happens when doing the same thing in a
"use" query. The simple1 and simple2 examples did this,
so it's likely that code exists that takes advantage of this
misfeature. New versions of these examples show how to index
through a StoreQueryResult without running past its end.
- ResUse used to delay creation of its FieldNames and FieldTypes
objects until the point of need. This had several implications
for thread and exception safety that we fix by just creating
them in the ctor. If your code is multi-threaded and was
avoiding certain usage patterns due to crashes, it's worth
trying your preferred way again.
- Result sets create a few data structures to hold information
common to all rows in that set. The row objects need access
to these shared data structures, so on creation each gets
a pointer back to the result set object that creates it.
This was efficient, but required that a result set object
outlive any row objects it creates. Now these shared data
structures are reference-counted, decoupling the lifetime of
the child row objects from their result set parent.
- Copy operations for result sets used to actually be "moves"
before, for efficiency. (MySQL++ itelf only copied result
sets in returning them by value from the query execution
methods of Query, so this was acceptable if you didn't do
anything uncommon with these objects.) Reference counted
data structures allow us to have copy semantics now without
sacrificing efficiency.
- You can now use Query::storein() with an STL container of Row
objects now, instead of having to use SSQLSes. The lifetime
issue guaranteed a crash if you tried this before.
- Removed a bunch of unnecessary alias methods:
- columns() -> num_fields()
- names() -> field_names()
- rows() -> num_rows()
- types() -> field_types()
- Renamed several methods for grammar reasons:
- fields(unsigned int) -> field(unsigned int)
- names(const std::string&) -> field_num(const std::string&)
- names(int) -> field_name(int)
- types(int) -> field_type(int)
- Removed several "smelly" methods:
- purge()
- raw_result()
- reset_names()
- reset_field_names()
- reset_types()
- reset_field_types()
o Field class used to just be a typedef for the corresponding C
API class. Now it's a real C++ class providing a more MySQL++
sort of interface, plus good OO things like information hiding
and implementation detail abstraction. This changes several
things about the interface.
o Fields class was basically a specialized std::vector work-alike
for dealing with the C API to get access to MYSQL_FIELD objects
and present them as contained Field objects. New Field type
let us replace it with "typedef std::vector<Field> Fields"
o Major improvements to the quoting and escaping mechanisms:
- Replaced almost all of the type-specific interfaces in manip.h
with a single version taking STA. The compiler can convert
almost anything to STA without losing any information we need
for correct quoting and escaping. This has the side benefit
that we can now do correct quoting and escaping for more data
types now, including plain C and C++ string types.
- Fixed a bug in quote_double_only manipulator for String: was
using single quotes by mistake.
- Escaping and quoting only works in instances where MySQL++
can tell you're building a SQL query and are using a data type
that requires it. This affects many things, but the one most
likely to cause trouble is that inserting MySQL++'s quoting
and escaping manipulators in non-Query ostreams is now a no-op.
- Added escape_string() member functions to Query and
SQLQueryParms::escape_string(), and removed the global function
of the same name. Because these are tied indirectly to a
Connection object, this also has the effect that escaping is
now aware of the current default character set used by the
database server. There's only one case where this isn't done
now, and that's when we're disconnected from the server.
- Previous two items form a trade-off: if your code was depending
on MySQL++ to get SQL escaping and it no longer happens for
what we consider a good reason, you can build a replacement
mechanism using these new functions. Quoting needs no special
support in MySQL++.
- Removed 'r' and 'R' template query parameter modifiers,
which meant "always quote" and "always quote and escape"
regardless of the data type of the parameter. There are no
corresponding manipulators (for good reason), so the removal
restores symmetry.
o Created DBDriver class from code previously in Connection and
Query to almost completely wrap the low-level MySQL C API:
- Connection creates a DBDriver object upon connection and
passes a pointer to it down to Query objects it creates.
In turn, they pass the pointer on to any of their children
that need access to the C API.
- Nothing outside DBDriver calls the C API directly now, though
DBDriver leaks C API data structures quite a lot, so this
feature doesn't constitute "database independence." See the
Wishlist for what must be done to get to that point.
o Completely redesigned the connection option setting mechanism:
- There's now just a single Connection::set_option() method that
takes a pointer to the abstract Option base class, and there is
an Option subclass for every connection option we understand.
Thus, type errors are now caught at compile time instead of
at run time.
- Replaced Connection::enable_ssl() with SslOption class.
- Enabling data compression and setting the connection timeout
are no longer set via parameters to Connection interfaces.
These are now set with CompressOption and ConnectTimeoutOption.
- Similarly, removed client_flag parameters from Connection's
ctor and connect() method and added corresponding Option
subclasses. There's about a dozen, so rather than list them
here, look for similarly-named classes in lib/options.h.
o Added Connection::count_rows() to execute "SELECT COUNT(*) FROM
tablename" queries for you.
o Moved Connection::affected_rows(), info() and insert_id() methods
to class Query, as they relate to the most recently-executed
query, not to the connection.
o Several method name changes in Connection:
- client_info() -> client_version()
- host_info() -> ipc_info()
- proto_info() -> protocol_version()
- server_info() -> server_version()
- stat() -> status()
o Removed Connection::api_version(). It does the same thing as
client_version().
o Lots of changes to Date, DateTime, and Time classes:
- If you use the default constructor for DateTime and don't
subsequently set its year, month, day, hour, minute or second
data members to nonzero values, it becomes the SQL function
"NOW()" in a query string. You can also use DateTime::now()
as syntactic sugar for this.
- As a result of above, had to hide all of DateTime's data
members behind accessor functions, to keep the state of the
object consistent. (If it's initialized as "now" and you
give it an explicit year value, say, it is no longer "now",
so the setter has to clear the now-flag.) There are getters
and setters for year, month, day, hour, minute and second,
all named after the member.
- Did the same for Date and Time for consistency, even though it
isn't technically required.
- The sql_timestamp typedef now aliases DateTime instead of Time.
- Renamed template class DTbase<T> to Comparable<T>. The fact
that it's the common base class of all date and time classes
is irrelevant; making subclasses comparable is what it does,
so that's what it should be named after.
- Added a DateTime ctor taking discrete year, month, day, hour,
minute, and second values.
- Implicit conversion from stringish types to the date and time
types is no longer allowed. This is part of the "Waba"
Null<T> patch mentioned above; allowing implicit conversions
would break this new feature.
- Added operator std::string and str() methods to all of these
classes. Adding this to the existing operator << support, you
now have several ways to convert these objects to string form.
- Added time_t conversion to Date and Time classes. DateTime
already had it, since it's more legitimate to convert time_t
to DateTime, but you could already "slice" it with something
like Time(DateTime(time(0))) so there's no point pretending
you can't get from time_t to Date or Time. Might as well
legitimize it.
o Improved tiny_int class:
- Turned it into a template parameterized on the value type so
you can get both signed and unsigned TINYINTs
- Changed the sql_tinyint and sql_tinyint_unsigned typedefs to
use mysqlpp::tiny_int<VT> instead of raw chars
- Added a bool conversion ctor and operator, and typedef'd it
to sql_bool and sql_boolean to match MySQL server behavior
o Added many more sql_* typedefs. We now have a typedef for every
type the MySQL server knows about, including those it supports
just for compatibility with other database servers.
o Changed the sql_*int* typedefs to use integer types of the same
size as the MySQL server. (Run test/inttypes.cpp to test it.)
o Added copy ctor and assignment operator to Row.
o Row::operator[]() takes int now instead of unsigned int.
This finally (!) makes it possible to say row[0] without the
compiler giving an ambiguous overload error.
o Changed all uses of row.at(0) in the examples to row[0]
o Added operator[] to all classes that only had at().
o Query now automatically resets itself unless the query fails
or you're using template queries. In either case, the contents
of the query's internal buffers are considered precious,
either for debugging, or future queries. Except when using
template queries, this means you may be able to avoid calling
Query::reset() entirely. It's still safe to call reset()
as before, just unnecessary most of the time.
o Removed reset_query parameter from all Query methods. It was
almost completely broken before, and above change does what
was really wanted to begin with.
o Query::store_next() and Result::fetch_row() no longer throw
the EndOfResults and EndOfResultSets exceptions; these are not
exceptional conditions! These methods simply return false now.
o Removed examples/usequery.cpp: there's no essential difference
between what it did and what examples/simple3.cpp does now as
a result of the previous change.
o Added Query::exec(void), paralleling Query::execute(void).
o Removed Query::preview(). The most direct replacement is str(),
which has always done the same thing.
o You can now insert a Query object into an ostream to get a copy
of the built query. This means Query::str() is only necessary
when using template queries.
o Removed overloads of Query::execute(), store(), and use()
that take const char*. It was redundant because const char*
converts implicitly to STA, for which overloads already exist.
o Renamed Query::def to Query::template_defaults to make its
purpose clearer.
o Query::error() now returns const char*, not a std::string by
value. There's no point in making a copy of the error string.
The method is now const as well, as it doesn't change the
Query object.
o Added Query::errnum(), which just wraps Connection::errnum().
o Added error number parameters and accessor functions to BadQuery,
ConnectionFailed and DBSelectionFailed exceptions, to preserve
the state of Connection::errnum() at the point of the exception,
so you don't have to rely on this value remaining unchanged
during the exception throw process. All places that use these
exceptions now include this value where possible. Thanks for the
initial patch go to Jim Wallace.
o Removed Lockable mechanism from Connection and Query; it was
conceptually flawed. See the new user manual chapter on
threading for advice on using MySQL++ safely without locking.
There is mutex locking now in ConnectionPool, but that's it.
o Connection::query() now takes an optional query string, allowing
the returned Query object to start off with a value. Especially
useful when the query string is static, either because it's
a simple query or because it's a template. You can now build
chains like "if (conn.query("CREATE INDEX ...").exec()) { ..."
o Added Connection::thread_aware(), thread_end(), thread_id()
and thread_safe(). See user manual's threading chapter for
explanations.
o Renamed "success" data members in Connection, Query and
SimpleResult (neé ResNSel) to "copacetic_", making them private
if they weren't before. This better reflects their actual
use, which isn't to say that there has necessarily been actual
success, but rather that everything's okay with the object.
o Removed success() member functions from above classes. All can
be tested in bool context to get the same information.
o Replaced all operator bool()s in MySQL++ classes with safer
alternatives. See http://www.artima.com/cppsource/safebool.html
Thanks to Jonathan Wakely for much helpful commentary, advice,
and code used in these mechanisms.
o Decoupled Connection::copacetic_ from Connection::is_connected_.
It is now possible for the object to be copacetic without being
connected. However, if it tries to connect and fails, then
it is not copacetic. If it is copacetic and not connected, it
means we haven't even tried to connect yet, a useful distinction.
o Collapsed Connection's host, port, and socket_name down into
a new combined 'server' parameter which is parsed to determine
what kind of connection you mean. These interfaces are still
compatible with v2.3 and earlier up through the port parameter.
There are differences beyond this.
o Added TCPConnection, UnixDomainSocketConnection and
WindowsNamedPipeConnection subclasses for Connection giving
simpler construction and connect() method interfaces for
instances where you know what kind of connection you want at
compile time.
o Changed Connection::ping() return value from int to bool.
o Renamed NullisNull to NullIsNull -- capital I -- and similar for
NullisZero and NullisBlank.
o It's now a compile-time error to try to convert a MySQL++
representation of a SQL null to any other data type, rather
than a run-time error as in previous versions. Removed
BadNullConversion exception as a result.
o Way back in v1.7.x we used the BadQuery exception for all kinds
of exceptional conditions, not just bad queries. Replaced
most of these in v2.0.0 with new dedicated exceptions, but a
few remained:
- Errors that occur during the processing of a "use" query after
the query itself executes correctly now throw UseQueryError.
It's not a "bad query", because the query executed
successfully. It just choked during subsequent processing,
so it's a different exception. Thanks for this patch go to
Jim Wallace.
- Replaced BadQuery exceptions thrown in Row constructor due
to bad ctor parameters with new ObjectNotInitialized exception
This is also Jim Wallace's work.
o The examples now all use getopt() type command line options
instead of positional options. This makes it possible to
pass options in any order, leave at their default options that
used to be in the middle of the sequence, and offer different
subsets of options for different programs. Also allows for
special internal-use options, like -D passed by dtest to let
examples change their behavior when run under dtest to produce
only predictable output.
o Split old libutil functionality into two modules, one holding
all the "print data" functions, and another holding all the
command line parsing stuff. This makes it easier for newbies
to ignore the command line stuff, treating it like a black box.
The wish to understand the "print data" routines is much more
common, so the two needed to be disentangled.
o Renamed examples' libutil to libexcommon.
o Removed connect_to_db() libutil function. It combined command
line parsing, which users don't care about, with database
connection establishment, which they do care about. Now the
examples just call out to libexcommon to parse the command
line, and use the values they get back to explicitly make the
connection, so it isn't hidden.
o Removed cchar and uint typedefs.
o Redesigned dbinfo example's output to be easier to read.
o Fixed an output formatting bug created in 2.3.0 that caused the
tabular output from examples to not line up.
o Renamed examples/tquery.cpp to tquery1.cpp. Created tquery2.cpp
to demonstrate passing parameters via a SQLQueryParametrs object
instead of discretely. Created tquery3.cpp for testing unquoted
template parameters, such as integers.
o Renamed fieldinf1.cpp example to fieldinf.cpp, and simplified
its output so it can be part of the dtest sequence.
o Renamed examples/xaction.cpp to transaction.cpp. It created too
much cognotive dissonance whenever thinking about both it and
lib/transaction.cpp.
o Added examples/deadlock.cpp, to test handling of exceptions due
to server-side transaction deadlock detection. Also added
code to resetdb to create a table needed to test this.
Initial version created by Jim Wallace to test the value of
all his BadQuery exception work, with reworking by me.
o Greatly expanded dtest suite. Primary change is that we now
have a handful of unit tests, where in v2.3.2 we only tested
a subset of the examples. Still very low coverage ratio,
but it's a big improvement.
o Optimized #includes, especially in lib/*.h to reduce
dependencies and thus compile time when one of these changes.
o Fixed a typo in RPM filename generation that prevented -devel
RPM from recognizing that the corresponding MySQL++ library
RPM was installed.
o RPM spec file improvements by Remi Collet.
o Renamed NO_LONG_LONGS to MYSQLPP_NO_LONG_LONGS to avoid a risk
of collision in the global macro namespace.
o First cut at Xcode2 project support. Testing needed!
o Debug build of library on VC++ and Xcode have a _d suffix now
so you can have both versions of the library installed without
conflict.
o Moved the VC++ 2003 project files into a new vs2003 subdirectory
because there are so many of them. Also created vs2005
subdirectory for VC++ 2005 and 2008 compatible project files.
2005 makes an even bigger mess of the directory containing
the .sln file, so the incentive is bigger. Plus, we have to
disable several things to get VC++ 2003 to build MySQL++ now,
so we need a special 2005+ version of the project files for a
complete build, if the user has one of the newer compilers.
o ...plus dozens of small bug fixes and internal enhancements,
many documentation improvements, and expansion of support for
newer operating systems and compilers.
2.3.2, 2007.07.11 (r1669)
o Previous release's const_string change caused more problems
than it fixed. This release contains the real fix. :)
o New Connection::set_option() handling deals with the multi
statements option correctly again. examples/multiquery now
runs again as a result.
o Added new unit testing script, called dtest. See the
HACKERS file for details. (This tool caught the previous
two problems!)
o Squished a GCC pedantic warning. Thanks for the patch go to
Andrew Sayers.
2.3.1, 2007.07.10 (r1659) The "After the Fireworks" release
o const_string objects now keep a copy of their data, not
just a pointer to it. This is less efficient, but necessary
to allow SSQLS to work with BLOBs. Without this, we were
seeing segfaults due to accessing freed memory pointed to
by the const_string, because the underlying object went
out of scope.
o Fixed many more potential embedded null handling problems
in manip.h.
o MySQL++ can now optionally reference MySQL C API headers as
being in a mysql subdirectory, a common thing on *ix systems,
by defining MYSQLPP_MYSQL_HEADERS_BURIED before #including
mysql++.h.
o Restored ColData_Tmpl<T>::get_string(), removed in v2.3.0,
along with warnings in the docs saying why you don't want
to use it, and what your alternatives are.
o VC++ and MinGW builds now define the HAVE_MYSQL_SSL_SET
macro, which lets you use the C API's SSL features.
This assumes your C API library does actually have these
features enabled, which is the case with the official binary
releases on Windows. (Builds on *ix systems continue to
test for these features at configure time.)
o Fixed simple examples-only Makefile generation, for RPMs.
2.3.0, 2007.07.02 (r1645)
o Added Query::for_each() and Query::store_if() methods
proposed by Joel Fielder, and added examples for each.
o It's now possible to store BLOB data in an SSQLS. It's not
foolproof, so added a section to the user manual (5.9) to
document the method. Also, changed examples/cgi_jpeg to use
this new mechanism, instead of the ugly "raw row data" method
it used to use.
o Revamped Connection::set_option() handling. These options
used to be queued up, and applied only just before actually
establishing the connection. This made error reporting less
helpful because the diagnostic was separated from the cause.
Plus, the error messages were misleading to begin with. Now,
set_option() takes effect immediately if the connection is not
yet up (excepting one special option that can actually be set
after the connection is up) and issues better diagnostics when
it detects errors.
o Connection::connect() used to set a few options in such a
way that the user couldn't override them. Now it's smart enough
to set them with the desired default values only when we see
that the user hasn't given them other values.
o SQLString can now be initialized from a mysqlpp::null,
giving a "NULL" string. This is useful for template queries.
Patch by Michael Hanselmann.
o resetdb error message about mixing library and header version
numbers is now more explicit.
o Changed BadConversion exception's "what" message text to be
more like the other exceptions. The inconsistency lead one
to incorrectly copy-paste code from another exception handler,
expecting it to behave the same way. Now it does.
o Added Row::raw_size(), as a shortcut for Row::at().size().
o ssqls-pretty now detects when it's being run from within
the MySQL++ distribution tree and gives a different -I flag
to the compiler, so that it picks up the distribution headers
instead of those that may be on the system already.
o The quote manipulator now works for char[] correctly.
Thanks for this patch go to Andrew Sayers. (It's always
worked for char*, but C++ doesn't consider that to be the
same type, so it used the generic quote handling path,
which doesn't do anything for char[].)
o Fixed a build bug on older Solaris versions where the
test for the C API library was erroneously failing, stopping
the configuration process.
o Simplified mysql_shutdown() level argument detection.
Already had to do a version number ifdef check for the
Windows case, so there's really no point to doing it with
autoconf on Unixy platforms. Moved version number check
into lib/connection.cpp, and nuked the separate autoconf and
Windows tests.
o Removed dependency of sql_types.h on myset.h and (indirectly)
datetime.h. Now we only define sql_* typedef aliases for those
MySQL++ types if the headers are included before sql_types.h.
o Fixed a typo in one of the storein_sequence() template
overloads, which is apparently rarely (or never?) used, because
no one reported the compiler error you'd get if you tried.
o Fixed a few more embedded null handling problems.
o ColData used to keep two copies of all data it held.
Now it keeps just one.
o Fixed install.bat script to track the unified Bakefile change
and the lack of separate debug and release builds under MinGW.
o Yet another STLport + Query memory leak fix.
o Squished a warning in newer GCCs having to do with identifier
shadowing. Patch by Jonathan Wakely.
o Fixed a null-termination bug in Query::parse(). If you
somehow constructed a query string without a terminating null
character, then tried to parse it as a template query, it could
walk off the end of the string. Patch by Worster Chen.
o Removed MYSQLPP_EXPORT tag from FieldNames and FieldTypes
class declarations, as this can cause problems in programs
that use vector<string> in VC++. It has to do with multiply
defined templates, since these classes derive from that
template, and VC++ can't resolve the conflict without help.
Since these classes aren't actually used outside the library,
this shouldn't cause a problem. Patch by Nils Woetzel.
o Partial fix to Doxygen PDF build on RHEL4 and 5. Needs
hand-coaxing to complete successfully on RHEL4, and doesn't
yet work at all on RHEL5.
o Shortened the "no*" options to the bootstrap script, so that
the usage message fits on a single line.
o Added "nodoc" bootstrap script option, for disabling the
documentation build during the dist target build. Allows for
building binary RPMs on CentOS 5.0, where doc building is
currently broken.
o Removed the updel example program. It was kind of silly,
and if you were to rewrite it today, you'd use for_each() anyway.
o Lots of documentation improvements.
2.2.3, 2007.04.17 (r1538) The "Tax Day" release
o Previous version left examples/vstudio/* out of the tarball
by accident.
o Improved generation of RPM temporary build directory path
name generation. Was using a hacked variant of the Fedora
Packaging Guidelines' second best choice. Now we're using
the choice they recommend most highly, without changes.
o Removed unnecessary resources from vstudio/wforms example.
o Minor URL fix in refman
2.2.2, 2007.04.13 (r1526) The "Nervousmaking Friday the 13th" release
o More small fixes to embedded null handling in Query.
o Fixed a bug in single-parameter template query handling.
o Added tquery example, to demonstrate proper use of template
queries. Previously, resetdb was the only exemplar, and
it wasn't really suited for that. This example also tests
the previous item.
o Added examples/vstudio/mfc, allowing us to improve the way
we demonstrate Unicode handling. Old way wasn't realistic.
On *ix, people will depend on the terminal code to handle
UTF-8. On Windows, users are almost certain to be writing
a GUI program, which requires different Unicode handling
than the old examples showed.
o Removed explicit Unicode conversion stuff from command line
examples, and reworked the Unicode chapter in the user
manual.
o Added examples/vstudio/wforms to show integration with
C++/CLI and Windows Forms. Documented this in README.vc.
o Rewrote load_file and cgi_image examples to be more
useful, renaming them to load_jpeg and cgi_jpeg along
the way. Also, resetdb now creates a second table in the
sample database for these two examples' use. Also, added
examples/logo.jpg to the distribution as sample data for
these examples.
o Limited the ostream base class casting stuff in Query to
VC++ 2003, which is the only platform that really needed it.
VC++ 2005 emits a warning with that hack in place, and on
other platforms it's just replicating work that the compiler
does already.
o Added library version information to main library target
so that systems that version shared libraries work as
expected. Thanks for this patch go to Jack Eidsness.
o Merged much of the diffs between Remi Collet's RPM spec file
into the official one.
o Reorganized the doc subdir a bit. Generated HTML is now all
under doc/html instead of scattered under other subdirs,
and renamed doc/README.mysql++ to doc/README.manuals.
o Improvements to top-level manual building make targets:
manuals now only rebuild at need, it's easier to request
a rebuild of all manuals, and we force a rebuild attempt
before building the distribution tarball so we don't ship
outdated manuals.
o Added ability to run examples under gdb using exrun,
using same mechanism as we currently have for valgrind.
Thanks for this patch go to Michael Hanselmann.
o Added "Important Underlying C API Limitations" chapter to the
user manual, to cover problems we keep seeing on the
mailing list that are the result of ignorance of the way
libmysqlclient behaves, not bugs MySQL++ is really in a
position to fix.
2.2.1, 2007.02.28 (r1433)
o Fixed the new localtime() alternative selection code
for VS2003 and various uses of STLport.
o No longer inserting a null character into the query stream
on calling one of the preview() functions. This was harmless
in v2.1, which used C strings more extensively, but began
causing problems in v2.2 due to its wider use of C++ strings.
o Fixed a bug in the Connection copy ctor where it didn't
completely initialize the object.
o Optimized Query::preview_char() a bit. Patch by Jonathan
Wakely.
o Reordered directory list used by autconf when locating the
MySQL C API library. The list is now ordered with the
most likely locations for the library first, so we're less
distracted by incorrect libraries. This fixes a specific
build error under RHEL4 with recent versions of MySQL 5.0.
2.2.0, 2007.01.23 (r1417)
o ColData, const_string, and SQLString can now be constructed
with an explicit length parameter. Furthermore, Query
class's execute(), store() and use() call chains terminate
in a version taking an explicit length parameter, instead
of one taking a simple C string. Together, this means
that it's now easier to handle data from the SQL server
containing nulls. The library is almost certainly not yet
capable of handling embedded nulls in all cases, but this
is a big first step towards that.
o Can now construct a DateTime object from a time_t, and
convert a DateTime back to a time_t. Patch by Korolyov Ilya.
o Changed the way we're handling exported functions in the
Windows DLL case so that it works more reliably under MinGW.
o Added proper copy semantics to Connection, so that you get a
new connection with the same parameters, not just a bitwise
copy of the object.
o Using an explicitly thread-safe variant of localtime() for
time conversions where one is available.
o Removed ListInsert template from myset.h. This wasn't used
within the library, and was never documented, so I'm betting
that no one actually uses it.
o Result::copy() was not copying the exception flag in
all cases. Fix by Steven Van Ingelgem.
o Added exrun shell script and exrun.bat files to distribution,
to avoid linkage errors when running the examples while
you still have an older version of MySQL++ installed.
o Renamed MYSQLPP_LIB_VERSION to MYSQLPP_HEADER_VERSION, as
what it really encodes is the version number in the mysql++.h
file you're using, not the actual library version number.
o Added mysqlpp::get_library_version(), which returns the
library version number at build time. Between this and
the header version constant, you can check that you're not
mixing MySQL++ header and library versions.
o resetdb example uses these new version number affordances to
double-check that you're not mixing libraries and headers
from different versions. This happens easily unless you
take care of it (such as by using exrun) when you have one
version of MySQL++ installed and you're trying to build and
test a new version without blowing away the old one first
or overwriting it.
o No longer using recursive Makefiles on Unixy platforms
or split lib + examples project files on VC++. Everything is
handled by a single top-level Makefile or project file, which
is simpler for the end user, and makes better dependency
management possible.
o When looking for the MySQL C library on systems using
autoconf, looking in .../lib64 wherever we are also looking
in .../lib.
o RPM build process no longer depends on Bakefile. It means
you have to build the examples when building an RPM even
though they're never used within the RPM, but it's a better
tradeoff in my opinion.
o Updated include and library paths on Windows to reflect
changes in the most recent MySQL installers.
o Merged lib/defs.h and lib/platform.h into new file,
lib/common.h. Just cleans up the library internals.
o Fixed build errors on Windows due to recent changes in MySQL.
o Fixed a few memory leaks and double-deletes in Query class.
o Fixed compatibility with STLPort's string implementation.
Patch by dengxy at cse.buaa.edu.cn.
o Fixed a compatibility problem between Set<> template and
SSQLS. Patch by Korolyov Ilya.
o Fixed build bug in SQLQueryParms due to a character
signedness issue on PowerPC with GCC. Patch by Michael
Hanselmann.
o ~Transaction() can no longer throw exceptions. It'll just
quietly eat them, to avoid program termination. Fix
suggested by Alex Burton.
o Fixed thread safety testing in autoconf case, accidentally
broken during v2.1.0 development cycle.
o Using Doxygen 1.5.1 to generate documentation.
2.1.1, 2006.04.04 (r1289)
o MinGW and Cygwin will now build and link to mysqlpp DLLs.
o Fixed bug in Query, causing it to initialize the "throw
exceptions" flag incorrectly. Thanks for this patch go to
Joel Fielder.
o Added -v flag for custom.pl script, which turns off the
multiply-defined static variable fix. Needed for VS 2003,
which doesn't support variadic macros. Also, added
a diagnostic to detect the need for the -v flag, and
suppressed the test for this feature in examples/util.cpp.
2.1.0, 2006.03.24 (r1269)
o Converted automake and makemake files to their equivalents in
Bakefile format.
o Added the Transaction class, which makes it easy to use
transaction sets in MySQL++.
o Added xaction example to test new Transaction class.
o Resetdb example now creates its example table using the
InnoDB storage engine, in order to test the new transaction
support. Resetdb also declares the table as using UTF-8
text; this doesn't change anything, but it does correctly
document what we're doing.
o Added sql_types.h header, containing C++ typedefs
corresponding to each MySQL column type. Using those new
types in the type_info module, and in the SSQLS examples.
o Replaced the way we were handling the template query
version of Query member functions, to allow an arbitrary
number of template query parameters. By default, we
now support 25 parameters, up from the old limit of 12.
It's now possible to change just one number, run a script,
and have a new limit.
o Connection class does a better job of returning error
messages if you call certain member functions that depend
on a connection to the server before the connection is
established.
o Updated libmysqlclient.def for newer versions of MySQL. (Fixes
build errors having to do with mysql_more_results() and
mysql_next_result().
o Replaced final use of strcpy() with strncpy().
o custom.pl now runs without complaint in strict mode, with
warnings turned on. Thanks for this patch go to "Waba".
o Fixed a bug in custom.pl where incorrect code would be
generated for some SSQLS set() methods. Thanks for this
patch go to "Waba".
o SSQLS structures now support long and unsigned long fields.
Thanks for this patch go to "Waba".
o It's now possible to put SSQLS definitions in a header
file used by multiple modules in a program without
getting multiple static member definition errors. See the
documentation for details. Thanks for this patch go to
Viktor Stark.
o Moved the definition of the 'stock' SSQLS out of the
custom*.cpp example files and into a new stock.h file.
Also, #including that file in the util module to test out
the new SSQLS multiple static definition fix.
o Using all of the digits of precision guaranteed by the
IEEE 754 spec when stringizing floating point numbers
to build queries. Previously, we would use the platform
default, which can be as few as 6 digits.
o Removed lib/compare.h. Not used within the library, never
documented, and nobody seems to want to defend it.
2.0.7, 2005.11.23 (r1147)
o Added explicit mysqlpp namespace qualifiers to generated code in
custom*.h so you can use SSQLS in places where it doesn't make
sense to say "using namespace mysqlpp" before the declaration.
Also updated some of the examples to not have this "using"
declaration to make it clear to users that it isn't needed, if you
want to use explicit namespace qualifiers as well. Thanks for
this patch to Chris Frey.
o Removed an apparently useless unlock() call from ResUse; there is
no nearby lock() call, so if this unlock() is in fact necessary,
it shouldn't be here anyway, because the two calls should be
nearby each other. Thanks for this patch to Chris Frey.
o Fixed Query ostream initialization bug affecting SunPro CC (at
least). While this bug violates the Standard, it doesn't affect
many real compilers because they don't enforce this rule. Fixed
by Chris Frey.
o Previously, we only used the C99 style "long long" support when
building under GNU CC. This is now the default. This should
allow the code to work under SunPro CC.
o Added another dynamic cast needed for proper Query ostream
subclass overloading under VC++. (7.1 at least...)
o Detecting whether MySQL is built with SSL support on platforms
using autotools. Needed on some old Sun systems, for instance.
Thanks for this patch to Ovidiu Bivolaru.
o Fixed a potential memory bug in ColData's conversion to SQL null.
o Many minor packaging tweaks. (README clarifications, file
permission fixes, better adherence to GNU packaging standards,
etc.)
2.0.6, 2005.09.28 (r1123)
o Fixed makemake.bat so it works on cmd.exe, not just 4NT.
o Documentation fixes.
2.0.5, 2005.09.13 (r1114)
o Visual C++ build now requires GNU make. It is tested to work
with either the Cygwin or the MinGW versions. The previous
version of MySQL++ used nmake. This change enabled the
following features:
o Debug and Release versions are both built into
separate subdirectories.
o Dependency tracking for release version works
correctly now. (Previously dependencies worked
only for debug version.)
o 'make clean' removes release version binaries
in addition to debug versions.
o MinGW makemake support updated to support new release/debug
subdirectory system. This is probationary support, since
this code currently can't be built as a DLL. As a result,
it is no more useful than the Cygwin version, for licensing
reasons.
o Several fixes to allow building on Solaris 8. These fixes may
also help on other SVR4-derived systems.
o Removed Borland C++ makemake support, because this version
of the library does not work completely, and there seems
to be almost no user interest in fixing it.
o Clarified "Handling SQL Nulls" section of user manual's
Tutorial chapter.
2.0.4, 2005.08.29 (r1076)
o Made mysql_shutdown() second parameter autoconf check less
sensitive to compiler pedantry.
o VC++ library Makefile is now smart enough to re-create the
import library, if it is deleted while leaving the DLL alone.
o Added libmysqlclient.def to tarball.
o Reworked most of the top-level README* files.
o Renamed LGPL file to LICENSE.
2.0.3, 2005.08.25 (r1060)
o Visual C++ makemake system updated to build both debug and
release versions of library DLL.
o Fixed bug in simple1 example that caused crashes on Windows.
o Doing UTF-8 to ANSI text translation in simple examples now.
o Previous two releases built libmysqlpp with wrong soname on
autotools-based systems. Fixed.
2.0.2, 2005.08.18 (r1050)
o Fixes to makemake system for cmd.exe.
o Fixed the case where the system's C++ library includes an slist
implementation in namespace std.
2.0.1, 2005.08.17 (r1046)
o Added new simple1 example, showing how to retrieve just one
column from a table. Old simple1 is now called simple2, and
simple2 is likewise shifted to simple3.
o Added custom6 example, showing how to do the same thing with
SSQLS.
o Updated user manual to cover new examples.
o Was accidentally shipping Subversion crap with tarball. Fixed.
2.0.0, 2005.08.16 (r1031) The "Excess Hair Removal" release
THIS IS NOT A DROP-IN REPLACEMENT FOR MySQL++ v1.7!
At minimum, you will have to recompile your program against
this library. You may also have to make code changes.
Please see the "Incompatible Library Changes" chapter of
the user manual for a guide to migrating your code to this
new version:
http://tangentsoft.net/mysql++/doc/html/userman/breakages.html
o The library's shared object file name (soname) scheme has
changed. (This mainly affects POSIX systems.)
The soname for the last 1.7.x releases of MySQL++ was
libmysqlpp.so.4, meaning the fourth version of the library's
application binary interface (ABI). (The first ABI version
in this scheme was that provided by 1.7.9.) MySQL++
2.0.0's soname is libmysqlpp.so.2.0.0. Since the dynamic
linker setup on some systems will create a symlink to
that file called libmysqlpp.so.2, it's possible that this
library could be confused with that for MySQL++ 1.7.19
through .21, which also used this number. Do not install
this library on a system which still has binaries linked
against that version of the library!
The new scheme is {ABI}.{feature}.{bug fix}. That is,
the first number changes whenever we break the library's
binary interface; the second changes when adding features
that do not break the ABI; and the last changes when the
release contains only internal bug fixes. This means
that we will probably end up with MySQL++ 3.0 and 4.0 at
some point, so there will be further soname conflicts.
Hopefully we can put these ABI changes off long enough
to avoid any real problems.
o autoconf now installs headers into $prefix/include/mysql++,
instead of $prefix/include. If you were using the
--includedir configure script option to get this behavior
before, you no longer need it.
o Linux binary RPMs will henceforth include only the
libmysqlpp.so.X.Y.Z file, and create any short names
required, to allow multiple versions to be installed at
once. Currently, you cannot install two MySQL++ library
RPMs at once, because they both have /usr/lib/libmysqlpp.so.X,
for instance.
o Replaced the Visual C++ and Borland C++ project files with
a new "makemake" system, which creates Makefiles specific
to a particular toolchain. This new mechanism also supports
MinGW and generic GCC-on-*ix. This was done partly to reduce
the number of places we have to change when changing the
file names in MySQL++ or adding new ones, and partly so we're
not tied to one particular version of each of these tools.
o VC++ Makefiles create a DLL version of the library only
now, so there's no excuse for LGPL violations now.
This same mechanism should make DLL builds under other
Windows compilers easy.
o Added Connection::enable_ssl(), which enables encrypted
connections to the database server using SSL.
o Connection::create_db() and drop_db() now return true on
success, not false.
o Connection::create_db() and drop_db() use Query::exec()
now, for efficiency, rather than Query::execute().
o Removed Connection::infoo(). Apparently just there to
save you from a typo when calling the info() method, since
it was a mere alias.
o Renamed Connection::real_connect() to connect(), gave
several more of its parameters defaults, and removed old
connect() function. Then changed user manual and examples
to use new APIs.
o Replaced Connection::read_option() with new set_option()
mechanism. The name change matches the method's purpose
better. Functional changes are that it returns true on
success instead of 0, it supports a broader set of options
than read_option() did, and it enforces the correct option
argument type.
o You can now call Connection::set_option() before the
connection is established, which will simply queue the option
request up until the connection comes up. If you use this
feature, you should use exceptions, because that's the only
way an option setting failure can be signalled in this case.
o Removed query-building functions (exec*(), store*(),
use()) from class Connection, and moved all the implementation
code to class Query. Query no longer delegates the final
step of sending the query to the database server to
Connection().
o Added Connection::enable_ssl(), for turning on SSL support on
a connection.
o Extracted exception disabling mechanism out of the many
classes that had the feature into a new OptionalExceptions
base class, which all classes having this feature now
derive from. Also, removed all per-method exception
handling flags. Finally, added NoExceptions class. With
all of these changes, there is now a common way to disable
exceptions with fine granularity on all objects that
support the feature.
o All custom MySQL++ exceptions now derive from the new
Exceptions class. This regularizes the exception interface
and allows you to use a single catch() block if you want.
o The "throw exceptions" flag is passed from parent to child
in all situations now. (Or if not, please report it as
a bug.) This fulfills a promise made in the v1.7.9 user
manual, with the cost being that some programs will see
new exceptions thrown that they're not expecting.
o Added a bunch of new exception types: BadOption,
ConnectionFailed, DBSelectionFailed, EndOfResults,
EndOfResultSets, LockFailed, and ObjectNotInitialized.
Some of these replace the use of BadQuery, which in v1.7.x
was a kind of generic exception, thrown when something more
specific wasn't available. Beware, this means that programs
may start crashing after recompiling them under v2.0 due to
uncaught exceptions, if they were only trying to catch BadQuery.
There are additional instances where the library will
throw new exceptions. One is when calling a method that
forces the internals to use an out-of-bounds index on a
vector; previously, this would just make the program
likely to crash. Another is that the library uses the
BadFieldName exception -- created in v1.7.30 -- in more
apropos situations.
o Renamed SQLQueryNEParms to BadParamCount, to match naming
style of other concrete exception types.
o Extracted lock()/unlock() functions from Connection and
Query classes into a new Lockable interface class. Locking
is implemented in terms of a different class hierarchy, Lock,
which allows multiple locking strategies with a single ABI.
o Removed ResUse::eof(). It's based on a deprecated MySQL
C API feature, and it isn't needed anyway.
o Removed arrow operator (->) for iterator returned by Fields,
Result and Row containers. It was inherently buggy, because
a correct arrow operator must return the address of an
object, but the underlying element access functions in these
classes (e.g. at()) return objects by value, of necessity.
Therefore, this operator could only return the address of
a temporary, which cannot be safely dereferenced.
o Returned Row subscripting to something more like the
v1.7.9 scheme: there are two operator[] overloads, one for an
integer (field by index) and another for const char* (field
by name). lookup_by_name() has been removed. Because row[0]
is ambiguous again, added Row::at() (by analogy with STL
sequence containers), which always works.
o Collapsed two of the Row::value_list*() overloads into
two other similar functions using default parameters.
This changes the API, but the removed functions aren't
used within the library, and I doubt they are used outside,
either.
o Merged RowTemplate into Row.
o Merged SQLQuery class into Query class.
o Query is now derived from std::ostream instead of
std::stringstream, and we manage our own internal string
buffer.
o Moved SQLParseElement and SQLQueryParms into their own
module, qparms.
o Added multiple result set handling to Query. MySQL 4.1
and higher allow you to give multiple SQL statements in a
single "store" call, which requires extensions to MySQL++
so you can iterate through the multiple result sets. Also,
stored procedures in MySQL 5.0 reportedly return multiple
result sets. Thanks for the initial patch go to Arnon Jalon;
I reworked it quite a bit.
o Query::storein*() now supports more varieties of the
nonstandard slist comtainer. (Singly-linked version of
STL std::list.)
o Template query mechanism and user manual had several
mismatches. Made manual match actual behavior, or
made library match documented behavior, as apropriate.
Initial patch by Jürgen MF Gleiss, with corrections and
enhancements by Warren Young.
o Collapsed mysql_* date and time base classes' methods and
data into the subclasses. Also, DateTime no longer derives
from Date and Time; you could get away with that in the
old hierarchy, but now it creates an inheritance diamond,
and allows unsupported concepts like comparing a Time to
a DateTime.
o Removed "field name" form of Row::field_list(). It was
pretty much redundant -- if you have the field names, why
do you need a list of field names?
o ColData can convert itself to bool now. Thanks for this
patch go to Byrial Jensen.
o Removed simp_list_b type; wasn't being used, and doesn't
look to be useful for end-user code.
o Several methods that used to take objects by value now
do so by const reference, for efficiency.
o Several variable and function renamings so that MySQL++
isn't needlessly tied to MySQL. Even if we never make
the library work with other database servers, there's
little point in tying this library to MySQL blindly.
o Renamed all private data members of MySQL++ classes to
have trailing underscores.
o 'private' section follows 'public' section in all classes
now.
o Removed mysql++.hh and sqlplus.hh backwards-compatibility
headers.
o Added copy ctors to Date/Time classes so that they will
work in SSQLS under GCC 4.0.0. Without these, the compiler
couldn't make the conversion from raw MySQL row data.
o Fixed a bunch of GCC 4.0 pedantic warnings: added virtual
dtors to all base classes, calling base class ctors from leaf
classes, etc.
o All warnings fixed under VC++ at warning level 3. (Mostly
harmless signedness and integer conversion stuff.)
o Updated LGPL license/copyright comments at the top of
several files to use FSF's new physical address.
o Relicensed user manual under a close variant of the Linux
Documentation Project License, as it's designed for
documentation, which the LGPL is not. Permission for this
received from Kevin Atkinson and MySQL AB.
o Added ABI and API breakages chapter to user manual. It
is basically a subset of this ChangeLog, with only the
information an end-user must know when migrating between
versions.
o Reworked user manual's DocBook code quite a bit after
reading Bob Stayton's book "DocBook XSL" 3/e. Better handling
of stylesheets, taking advantage of some superior DocBook
features, prettier output (especially the HTML version), etc.
o Rewrote doc/userman/README to make it clearer how to get
started contributing to the user manual. It's essentially a
"getting started with DocBook" guide now!
o Lots of small text improvements to user and reference
manuals. Aside from the obvious tracking of library changes,
made a bunch of minor style and clarity improvements.
o Added CSS stylesheets for userman and refman to
make the HTML versions of each a) not ugly; and b) match
tangentsoft.net. (Yes, some may say that these are incompatible
goals....)
o Standardized exception handling code in the examples that
use it.
o Fixed a potential memory leak due to exceptions thrown from
ResUse. Thanks for this patch go to Chris Frey.
o Using new "no exceptions" feature of library in simple1
example, so it is now truly simple.
o simple1 example no longer depends as much on util module, so
that all of the important code is in one place. Makes
learning MySQL++ a little less intimidating.
o Added new simple2 and usequery examples, to demonstrate
the proper way to handle a "use" query, with exceptions
disabled, and not, respectively. Added them to the user
manual, in the appropriate place.
o Refactored the "print stock table" example functions
again, to make code using them clearer.
o UTF-8 to UCS-2 handling in examples is now automatic on
Windows.
o Removed debug code from Windows Unicode output examples
that slipped into previous release.
o resetdb example is now clearer, and more robust in the
face of database errors.
o Simplified connect_to_db() in examples' util module.
o Added sample autoconf macro for finding MySQL++ libraries, for
people to use in their own autotools-based projects.
o Lots and lots of minor cleanups not worth mentioning
individually...
1.7.40, 2005.05.26 (r719)
o Multiple item form of insert() now works if you're using the
SQLQuery class, or its derivative, Query. Thanks to Mark
Meredino for this patch.
o Fixed a bug in const_string::compare(), in which MySQL++
would walk off the end of the shorter of the two strings.
All was well if the two were the same length.
o ResUse::operator=() now fully updates the object, so it's more
like the behavior of the full ctor.
o All source files now contain a license and copyright statement
somewhere within them.
o Optimized mysql++.h a bit: it now #includes only the minimum set
of files required, and there is now an idempotency guard.
This improves compile times a smidge, but mainly it was
done to clean up the generated #include file graph in the
reference manual. Before, it was a frightful tangle because
we #included everything except custom*.h.
o Constness fix in MySQL++ date/time classes to avoid compiler
warnings with SSQLS. Thanks to Wolfram Arnold for this patch.
o Fixed some compiler warnings in custom*.h. Thanks to Chris Frey
for this patch.
o Added "Submitting Patches" and "Maintaining a Private CVS
Repository" sections to the HACKERS file. Thanks to Chris
Frey for the source material for these sections. The HACKERS
file was improved in several other ways at the same time.
o PDF version of user manual no longer has links to the reference
manual. They were ugly, and they were broken anyway due to the
way we move the PDFs after generating them. If you want
interlinked manuals, use the HTML version.
o PDF version of user manual now has hard page breaks between
chapters.
o Removed complic1 example. Wasn't pulling its own weight.
Everything it is supposed to demonstrate is shown in other
examples already.
o Refactored print_stock_table() in examples/util module to be
four functions, and made all the examples use various of
these functions where appropriate. Before, several of
the examples had one-off stock table printing code because
print_stock_table() wasn't exactly the right thing, for one
reason or another. One practical problem with this is that
some of the examples missed out on the recent Unicode updates;
now such a change affects all examples the same way.
o Since so many of the examples rely on the util module, the user
manual now covers it. The simple1 example in the user manual
didn't make much sense before, in particular, because it's
really just a driver for the util module.
o Added custom5 example. It shows how to use the equal_list()
functionality of SSQLS. Thanks to Chris Frey for the original
version of this program. (I simplified it quite a bit after
accepting it.)
o New user manual now covers the value_list(), equal_list() and
field_list() stuff that the old manual covered but which was
left out in previous versions of the new manaul. Most of the
examples are the same, but the prose is almost completely new.
This new section includes the custom5 example.
o Every declaration in MySQL++ is now documented in the reference
manual, or explicitly treated as "internal only".
o Improved docs for MySQL++'s mechanism to map between MySQL
server types and C++ types. Initial doc patch by Chris Frey,
which I greatly reworked.
o Improved a lot of existing reference manual documentation while
adding the new stuff.
o Expanded greatly on the exception handling discussion in the user
manual.
o Added all-new "Quoting and Escaping" section to the user
manual's Tutorial chapter. Moved some existing comments on
quoting and escaping around and added some new ones to other
sections as a result.
o Added all-new "Handling SQL Nulls" section to the user manual's
Tutorial chapter.
o Many improvements to the Overview section of the user manual.
o Row::operator[] reference now explains the right and wrong way to
use the values it returns. This is in response to a mailing list
post where someone was incorrectly using this feature and getting
a bunch of dangling pointers.
o Updated Doxyfile so 1.3.19.1 parses it without warnings. Still
works with versions back to 1.2.18, at least. (These are
the versions shipped with Fedora Core 3 and Red Hat Linux 9,
respectively.)
o Using a superior method to make Doxygen ignore certain sections
of the source code. Between this change and the fact that
everything not so ignored is documented, Doxygen no longer
generates any warnings.
o Lots of code style updates. Everything should now be consistently
formatted.
1.7.35, 2005.05.05 (r601) The "Cinco de Mayo" release
o Added a "how to use Unicode with MySQL++" chapter to the user
manual. (Too bad "Cinco de Mayo" doesn't have any accented
characters. That would be just _too_ precious.)
o VC++ examples now use the Unicode Win32 APIs, so they can display
Unicode data from MySQL++.
o Added an optional conversion function to examples/util.cpp to
handle the conversion from UTF-8 to UCS-2 on Win32.
o Moved "brief history of MySQL++" from intro section of refman to
intro section of userman.
o Lots of small bits of documentation polishing.
o Made some minor constness fixes. Thanks to Erwin van Eijk
for this patch.
o Made some warning fixes for GCC 4.0. Not all warnings are
fixed, because some of the needed changes would break the ABI.
Thanks to Chris Frey for this patch.
o Added lib/Doxyfile to distribution.
1.7.34, 2005.04.30 (r573)
o Added a multiple-insert method for Query, which lets you insert
a range of records from an STL container (or the whole thing,
if you like) in a single SQL query. This is faster, and it
reduces coding errors due to less repetition. Thanks to Mark
Meredino for the patch.
o Reference and user manual now get rebuilt automatically when
required. (E.g. on 'make dist', or explicitly now through 'make
docs'.)
o Made it easier to change the maximum number of SSQLS data members
in generated custom-macros.h file. It used to be hard-coded in
several places in lib/custom.pl; now it's a variable at the top of
the file.
o Changed default SSQLS data member limit to 25, which is what it
has been documented as for a long time now. It was actually 26
within custom.pl.
o Fixed a regression in previous version.
o Trimmed some fat from the distribution packages.
o Some more small doucmentation improvements.
1.7.33, 2005.04.29 (r555)
o Worked around an overloaded operator lookup bug in VC++ 7.1
that caused SSQLS insert, replace and update queries to get
mangled. (Symptom was that custom2 and custom3 examples didn't
work right.) Thanks to Mark Meredino for digging up the
following, which explains the problem and gives the solution:
http://groups-beta.google.com/group/microsoft.public.vc.stl/browse_thread/thread/9a68d84644e64f15
o Some VC++ warning fixes.
o Major documentation improvements:
o Using DocBook for user manual and Doxygen for reference
manual. The former now references the latter where
useful.
o Split out HACKERS and CREDITS files from main README,
and improved remaining bits of README.
o Moved the text from the old v1.7.9 LaTeX-based
documentation over into the new systems, and reworked
it to more closely resemble English.
o Added a lot of new material to documentation, and
simplified a lot of what already existed.
o Documentation is now being built in HTML and PDF forms.
o ebuild file updated to take advantage of recent configure script
features. Thanks to Chris Frey for this patch.
1.7.32, 2005.03.10 (r479)
o Example building may now be skipped with --disable-examples
configure script flag.
o Changed stock items added in resetdb. One is now UTF-8 encoded,
to show that basic use of Unicode with MySQL++ is easy, yet not
foolproof. (See formatting of table on systems where cout isn't
UTF-8 aware!) Other stock items now follow a theme, for your
amusement. :)
o custom3 example now changes UTF-8 item's name to the 7-bit ASCII
equivalent. Previously, this example would fix a spelling error
in the table.
o resetdb example now says 'why' when it is unable to create the
sample database.
o Small formatting change to print_stock_table(), used by several
examples.
o Was issuing a VC++-specific warning-disable pragma when built by
any Windows compiler. Fixed.
1.7.31, 2005.03.05 (r462) The "Inevitable Point-one Followup" release
o Check for threads support must now be explicitly requested via
configure script's new --enable-thread-check flag.
o Fix for contacting MySQL server on a nonstandard port number.
Thanks to Chris Frey for this patch.
o Example programs using standard command line format now accept a
fourth optional parameter, a port number for the server. Thanks
to Chris Frey for this patch.
o One more g++ 3.4 pedantic warning fix by Chris Frey.
o Exception handling in resetdb is no longer nested, because you'd
get a segfault on some systems when an exception was thrown from
one of the inner try blocks.
o Improvements to Connection class's handling of locking mechanism.
Concept based on patches by Rongjun Mu.
o Implemented the declared-but-never-defined Query::lock(). Thanks
to Rongjun Mu for this patch.
o Cleaned up some unclear if/else blocks in connection.cpp by
adding explicit braces, correct indenting and putting normal
code path in the if side instead of the else.
1.7.30, 2005.02.28 (r443) The "Power of Round Numbers" release
o bootstrap script now accepts a 'pedantic' argument, which sets a
bunch of CFLAGS that make g++ very picky about the code it
accepts without warnings.
o Fixed a bunch of things that generated warnings with g++ in
pedantic mode. Only two warnings remain, having to do with
floating point comparisons. (See Wishlist for plans on how to
deal with these.) Thanks to Chris Frey for this patch.
o Split long tests out of configure.in into M4 files in new config
subdir. This makes configure.in easier to read.
o Added preliminary thread support. Currently, this just means that
we detect the required compiler and linker thread flags, and link
against the proper thread-safe libraries. THERE MAY BE
UN-THREAD-SAFE CODE IN MYSQL++ STILL!
o Standard C++ exceptions are the default now. Old pre-Standard
exception stuff removed.
o Row::lookup_by_name() will throw the new BadFieldName exception if
you pass a bad field name. Thanks for this patch to Chris Frey.
o Row::operator[] will throw a Standard C++ out of bounds exception
by way of std::vector::at() if you pass it a bad index. Thanks
for this patch to Chris Frey.
o Setting Connection::is_connected flag to false on close().
Previously, is_connected() would continue to return true after
close() was called.
o All number-to-string conversion ctors in SQLString class now use
ostringstream to do the conversion. Previously, we used
snprintf(), which isn't available on all systems. Also, we used a
C99 format specifier for the "long long" conversion, which is also
not available on all systems. This new ostringstream code should
be platform-independent, finally.
1.7.28, 2005.02.04 (r403)
o --with-mysql* flags to configure script now try the given
directory explicitly, and only if that fails do they try
variations, like tacking '/lib' and such onto it to try and find
the MySQL includes and libraries. Thanks to Matthew Walton for
the patch.
o Finally removed sql_quote.h's dependence on custom.h, by moving
the one definition it needed from custom.h to deps.h. This will
help portability to compilers that can't handle the SSQLS macros,
by making that part of the library truly optional.
1.7.27, 2005.01.12 (r395)
o configure check for libmysqlclient now halts configuration if the
library isn't found. Previously, it would just be flagged as
missing, and MySQL++ would fail to build.
o Added sql_string.cpp to VC++ and BCBuilder project files.
o Removed Totte Karlsson's 'populate' example, which never made it
into the distribution anyway.
o Removed last vestiges of 'dummy.cpp'.
o Renamed *.cc to *.cpp in BCBuilder project files.
o Worked around a BCBuilder C++ syntax processing bug in row.h.
1.7.26, 2004.12.17 (r382)
o Moved all of the SQLString definitions out of the header and into
a new .cpp file, reformatted it all, and made the integer
conversion functions use snprintf() or _snprintf() instead of
sprintf(). Also, widened some of the buffers for 64-bit systems.
o Using quoted #include form for internal library headers, to avoid
some problems with file name clashes. (The headers should still
be installed in their own separate directory for best results,
however.) Thanks to Chris Frey and Evan Wies for the patch and
the discussion that lead to it.
o Removed unnecessary semicolons on namespace block closures.
Thanks to Evan Wies for this patch.
o Fixed namespace handling in the legacy headers mysql++.hh and
sqlplus.hh. Thanks to Chris Frey for this patch.
o #including iostream instead of ostream in lib/null.h for
broader C++ compatibility. (This may allow MySQL++ to work on GCC
2.95.2 again, but this is unconfirmed.)
o Detecting proper mysql_shutdown() argument handling automatically
in platform.h for the Windows compiler case instead of making the
user edit the file. Thanks to Evan Wies for this patch.
o Fixed examples/Makefile.simple to use new *.cpp file naming.
o Fix to Gentoo ebuild file's exception configure switch handling.
Thanks to Chris Frey for this patch.
o Rebuilding lib/custom*.h intelligently now, to avoid unnecessary
recompiles after running bootstrap script.
1.7.25, 2004.12.09 (r360)
o Yet more fixes to the --with-mysql-lib and --with-mysql-include
flags.
o Added DLLEXPORT stuff to platform.h, hopefully so that someone
can figure out how to make VC++ make a DLL version of MySQL++.
o Renamed *.cc to *.cpp.
o Made 'set -> myset' change in VC++ project files.
o Some style changes (mostly whitespace) in header files.
1.7.24, 2004.12.08 (r343)
o Fixed the --with-mysql-lib and --with-mysql-include flags'
behavior, and extended their search ability to handle one other
common case. (Fixed by Steve Roberts)
o Fixes to put freestanding functions in namespace mysqlpp. (They
weren't in the namespace, while all the class member functions
were.) This required bumping the ABI version number to 4.
o Renamed set module to myset, to avoid conflicts with Standard C++
Library's set.h when MySQL++ headers were installed into one of
the standard system include directories.
o Renamed all the idempotency guards to make them consistent in
style and unique to MySQL++.
o Reformatted all of lib/*.cc.
1.7.23, 2004.11.20 (r333)
o Query::reset() now empties the stored query string. If you
subsequently stored a longer query in the object, you'd overwrite
the previous query, but otherwise the longer part of the previous
one would stick out past the new query.
o We now look to the NO_LONG_LONGS macro only to decide whether to
fake 64-bit integer support using 32-bit integers.
o 64-bit integer support under Visual C++ may be working now, using
that platform's __int64_t type. This has not been tested.
o Removed 64-bit integer support for Codewarrior on Mac OS 9 and
earlier. OS X uses GCC, so it requires no special support.
o Added MinGW detection in platform.h.
o If you pass a flag (-X) to the examples that take the standard
parameters (resetdb, simple1, etc.), it prints a usage message.
o Better error handling in resetdb example, where errors are the
most critical. (If that one runs without errors, the others
probably will, too, and you have to run that one first.)
o resetdb now reports success, rather than succeeding silently.
o Removed the code in sample1 example that duplicated util module's
print_stock_table(), and called that function instead.
o Moved the preview() calls in the example programs to before the
query execution calls, because execution modifies the query.
o All examples that take the standard command line parameters now
exit when connect_to_db() fails in one of the ways that don't
throw an exception, rather than bulling onward until the next
MySQL database call fails because the connection isn't up.
o dbinfo example now takes the standard command line parameters.
o Much better output formatting in dbinfo example.
o Calling reset() where appropriate in the various example programs.
Before, the programs may have worked, but not for the right
reason. This lead some people to believe that calling reset()
was not necessary.
o Fixed an incorrect use of row["string"] in complic1 example.
o Lots of code style improvements to the examples.
o Some VC++ type warnings squished. Some remain.
1.7.22, 2004.11.17 (r302)
o Applied patches by Zahroof Mohammed to allow it to build under GCC
3.4.2. Tested on MinGW and Fedora Core 3 systems.
o Removed all the forward declarations in defs.h, and added
forward declarations where necessary in individual header files.
#including defs.h in fewer locations as a result.
o Legacy headers sqlplus.hh and mysql++.hh now declare they are
using namespace mysqlpp, to allow old code to compile against the
new library without changes.
o Removed query_reset parameter from several class Query member
functions. In the implementation, these parameters were always
overridden! No sense pretending that we pay attention to these
parameters. This changes the ABI version to 3.
o #including custom.h in sql_query.h again...it's necessary on GCC
3.4.
o bootstrap script runs lib/config.pl after configure. This is
just a nicety for those running in 'maintainer mode'.
1.7.21, 2004.11.05 (r273)
o Generating a main mysql++ RPM containing just the library files
and basic documentation, and the -devel package containing
everything else.
o Devel package contains examples now, along with a new Makefile
that uses the system include and library files, rather than the
automake-based Makefile.am we currently have which uses the files
in the mysql++ source directory.
o Renamed sqlplusint subdirectory in the package to lib.
o Removed the obsolete lib/README file.
o lib/sql_query.h no longer #includes custom.h, simplifying
build-time dependencies and shortening compile times.
1.7.20, 2004.11.03 (r258)
o Collapsed all numbered *.hh headers into a single *.h file. For
example, the contents of row1.hh, row2.hh and row3.hh are now in
row.h.
o While doing the previous change, broke several circular
dependencies. (The numbered file scheme was probably partly done
to avoid this problem.) The practical upshot of most of these
changes is that some functions are no longer inline.
o Removed define_short.hh and everything associated with it. The
library now uses the short names exclusively (e.g. Row instead of
MysqlRow).
o Put all definitions into namespace mysqlpp. For most programs,
simply adding a 'using namespace mysqlpp' near the top of the
program will suffice to convert to this version.
o Once again, the main include file was renamed, this time to
mysql++.h. Hopefully this is the last renaming!
o mysql++.hh still exists. It emits a compiler warning that the
file is obsolete, then it #includes mysql++.h for you.
o sqlplus.hh is back, being a copy of the new mysql++.hh. Both of
these files may go away at any time. They exist simply to help
people transition to the new file naming scheme.
o Renamed mysql++-windows.hh to platform.h, and added code to it to
handle #inclusion of config.h on autotools-based systems
intelligently. This fixes the config.h error when building under
Visual C++.
o There is now only one place where conditional inclusion of
winsock.h happens: platform.h.
o Beautified the example programs.
1.7.19, 2004.10.25 (r186)
o Fixed an infinite loop in the query mechanism resulting from the
strstream change in the previous version. There is an overloaded
set of str() member functions that weren't a problem when query
objects were based on strstream.
o Query mechanism had a bunch of const-incorrectness: there were
several function parameters and functions that were const for
the convenience of other parts of the code, but within these
functions the constness was const_cast away! This was evil
and wrong; now there are fewer const promises, and only one is
still quietly broken within the code. (It's in the SQLQuery
copy ctor implementation; it should be harmless.)
o Removed operator=() in Query and SQLQuery classes. It cannot take
a const argument for the same reason we have to cast away const
in the SQLQuery copy ctor. It's tolerable to do this in the copy
ctor, but intolerable in an operator. Since the copy ctor is good
enough for all code within the library and within my own code, I'm
removing the operator.
o Above changes required bumping the ABI to version 2.
o Visual C++ projects now look for MySQL build files in c:\mysql,
since that's the default install location. (Previously, it was
c:\program files\mysql.)
1.7.18, 2004.10.01 (r177)
o Changed all the strstream (and friends) stuff to stringstream type
classes. Let there be much rejoicing.
o Query object now lets you use store() even when the SQL query
cannot return a result, such as a DROP TABLE command. This is
useful for sending arbitrary SQL to the server. Thanks to
Jose Mortensen for the patch.
o Quote fix in configure.in, thanks to David Sward.
o Renamed undef_short file to undef_short.hh.
o Gentoo ebuild file is actually being shipped with the tarball,
instead of just sitting in my private CVS tree since 1.7.14 was
current. Ooops....
1.7.17, 2004.09.16 (r170)
o Reverted one of the VC++ warning fix changes from 1.7.16 that
caused crashes on Linux.
o Added a configure test that conditionally adds the extra 'level'
parameter to mysql_shutdown() that was added in MySQL 4.1.3 and
5.0.1.
1.7.16, 2004.09.13 (r160)
o Building VC++ version with DLL version of C runtime libraries, and
at warning level 3 with no warnings emitted.
o VC++ build no longer attempts to fake "long long" support. See
the Wishlist for further thoughts on this.
1.7.15, 2004.09.02 (r144)
o Renamed Configure file to common.am, to avoid file name conflict
with configure script on case-sensitive file systems.
o Added ebuild file and ebuild target to top-level Makefile for
Gentoo systems. Thanks to Chris Frey for this.
o Small efficiency improvements to BadQuery exception handling.
Initial idea by Chris Frey, improvements by Warren Young.
1.7.14, 2004.08.26 (r130)
o Builds with Visual C++ 7.1.
o Fixed a bug in custom macro generation that caused problems with
GCC 3.4. (X_cus_value_list ctor definition was broken.)
1.7.13, 2004.08.23 (r92)
o Removed USL CC support. (System V stock system compiler.) Use
GCC on these platforms instead.
o Added examples/README, explaining how to use the examples, and
what they all do.
o Most of the example programs now accept command line arguments for
host name, user name and password, like resetdb does.
o Renamed sinisa_ex example to dbinfo.
o Several Standard C++ syntax fixes to quash errors emitted by
GCC 3.4 and Borland C++ Builder 6. Thanks to Steffen Schumacher
and Totte Karlsson for their testing and help with these.
o Added proper #includes for BCBuilder, plus project files for same.
Thanks to Totte Karlsson for these.
1.7.12, 2004.08.19 (r63)
o Many Standard C++ fixes, most from the GCC 3.4 patch by
Rune Kleveland.
o Added Wishlist file to distribution.
o Fixed a problem in the bootstrap script that caused complaints
from the autotools on some systems.
o RPM building is working properly now.
o Fixed the idempotency guard in datetime1.hh.
1.7.11, 2004.08.17 (r50)
o Renamed mysql++, defs and define_short files, adding .hh to the
end of each. (They're header files!) This shouldn't impact
library users, since these are hopefully used internal to the
library only.
o Removed sqlplus.hh file. Use mysql++.hh instead.
o Added mysql++.spec, extracted from contributed 1.7.9 source RPM,
and updated it significantly. Also, added an 'rpm' target to
Makefile.am to automate the process of building RPMs.
o Added bootstrap and LGPL files to distribution tarball.
o Added pre-1.7.10 history to this file.
o Removed .version file. Apparently it's something required by old
versions of libtool.
1.7.10, 2004.08.16 (r27)
o Maintenance taken over by Warren Young (mysqlpp at etr dash usa
dot com.) See http://lists.mysql.com/plusplus/3326 for details.
o Applied many of the GCC 3.x patches submitted for 1.7.9 over
the years. This allows it to build on everything from 3.0 to
3.3.3, at least. Because so many patches are rolled up in one
big jump, it's difficult to describe all the changes and where
they came from. Mostly they're Standard C++ fixes, as GCC
has become more strict in the source code that it will accept.
o MysqlRow used to overload operator[] for string types as well as
integers so you could look up a field by its name, rather than by
its index. GCC 3.3 says this is illegal C++ due to ambiguities in
resolving which overload should be used in various situations.
operator[] is now overloaded only for one integer type, and a
new member function lookup_by_name() was added to maintain the old
by-field-name functionality.
o Fixed another operator overloading problem in SSQLS macro
generation with GCC 3.3.
o The _table member of SSQLS-defined structures is now const char*,
so you can assign to it from a const char* string.
o Got autoconf/automake build system working with current versions
of those tools again. Removed the generated autotools files from
CVS.
o Renamed library file from libsqlplus to libmysqlpp.
1.7.9 (May 1 2001) Sinisa Milivojevic <sinisa@mysql.com>
* Fixed a serious bug in Connection constructor when reading MySQL
* options
* Improved copy constructor and some other methods in Result /
* ResUse
* Many other minor improvements
* Produced a complete manual with chapter 5 included
* Updated documentation, including a Postscript format
1.7.8 (November 14 2000) Sinisa Milivojevic <sinisa@mysql.com>
* Introduced a new, standard way of dealing with C++ exceptions.
* MySQL++ now supports two different methods of tracing exceptions.
* One is by the fixed type (the old one) and one is standard C++
* type by the usage of what() method. A choice of methods has to be
* done in building a library. If configure script is run with
* -enable-exception option , then new method will be used. If no
* option is provided, or -disable-exception is used, old MySQL++
* exceptions will be enforced. This innovation is a contribution of
* Mr. Ben Johnson <ben@blarg.net>
* MySQL++ now automatically reads at connection all standard MySQL
* configuration files
* Fixed a bug in sql_query::parse to enable it to parse more then 99
* char's
* Added an optional client flag in connect, which will enable usage
* of this option, e.g. for getting matched and not just affected
* rows. This change does not require any changes in existing
* programs
* Fixed some smaller bugs
* Added better handling of NULL's. Programmers will get a NULL
* string in result set and should use is_null() method in ColData to
* check if value is NULL
* Further improved configuration
* Updated documentation, including a Postscript format
1.7.6 (September 22 2000) Sinisa Milivojevic <sinisa@mysql.com>
* This release contains some C++ coherency improvements and scripts
* enhacements
* result_id() is made available to programmers to fetch
* LAST_INSERT_ID() value
* Connection constroctur ambiguity resolved, thanks to marc@mit.edu
* Improved cnnfigure for better finding out MySQL libraries and
* includes
* Updated documentation, including a Postscript format
1.7.5 (July 30 2000) Sinisa Milivojevic <sinisa@mysql.com>
* This release has mainl bug fixes and code improvements
* A bug in FieldNames::init has been fixed, enabling a bug free
* usage of this class with in what ever a mixture of cases that is
* required
* Changed behaviour of ResUse, Result and Row classes, so that they
* could be re-used as much as necessary, without any memory leaks,
* nor with any re-initializations necessary
* Fixed all potential leaks that could have been caused by usage of
* delete instead of delete[] after memory has been allocated with
* new[]
* Deleted all unused classes and macros. This led to a reduction of
* library size to one half of the original size. This has
* furthermore brought improvements in compilation speed
* Moved all string manipulation from system libraries to
* libmysqlclient, thus enabling uniformity of code and usage of 64
* bit integers on all platforms, including Windows, without
* reverting to conditional compilation. This changes now requires
* usage of mysql 3.23 client libraries, as mandatory
* Changed examples to reflect above changes
* Configuration scripts have been largely changed and further
* changes shall appear in consecutive sub-releases. This changes
* have been done and shall be done by our MySQL developer Thimble
* Smith <tim@mysql.com>
* Changed README, TODO and text version of manual. Other versions of
* manual have not been updated
* Fixed .version ``bug''. This is only partially fixed and version
* remains 1.7.0 due to some problems in current versions of libtool.
* This shall be finally fixed in a near future
* Several smaller fixes and improvements
* Added build.sh script to point to the correct procedure of
* building of this library. Edit it to add configure options of your
* choice
1.7 (May17 2000) Sinisa Milivojevic <sinisa@mysql.com>
* This is mainly a release dealing with bug fixes, consistency
* improvements and easier configure on some platforms
* A bug in fetch_row() method of ResUse class has been fixed. Beside
* changes that existed in a distributed patch, some additional error
* checking has been introduced
* A bug in escape manipulator has been fixed that could cause an
* error if all characters had to be escaped
* An inconsistency in column indexing has been fixed. Before this
* version, column names in row indexing with strings, i.e.
* row[<string>] , has been case sensitive, which was inconsistent
* with MySQL server handling of column names
* An inconsistency in conversion from strings to integers or floats
* has been fixed. In prior version a space found in data would cause
* a BadConversion exception. This has been fixed, but 100%
* consistency with MySQL server has not been targeted, so that other
* non-numeric characters in data will still cause BadConversion
* exception or error. As this API is used in applications, users
* should provide feedback if full compatibility with MySQL server is
* desired, in which case BadConversion exception or error would be
* abolished in some of future versions
* A new method in ColData class has been introduced. is_null()
* method returns a boolean to denote if a column in a row is NULL.
* Finally, as of this release, testing for NULL values is possible.
* Those are columns with empty strings for which is_null() returns
* true.
* Some SPARC Solaris installations had C++ exception problems with
* g++ 2.95.2 This was a bug that was fixed in GNU gcc, as from
* release 2.95 19990728. This version was thoroughly tested and is
* fully functional on SPARC Solaris 2.6 with the above version of
* gcc.
* A 'virtual destructor ' warning for Result class has been fixed
* Several new functions for STL strings have been added. Those
* functions (see string_util.hh) add some of the functionality
* missing in existing STL libraries
* Conversion for 64 bit integers on FreeBSD systems has been added.
* On those systems _FIX_FOR_BSD_ should be defined in CXXFLAGS prior
* to configuring. Complete conversion to the usage of functions for
* integer conversion found in mysqlclient library is planned for one
* of the next releases
* A completely new, fully dynamic, dramatic and fully mutable result
* set has been designed and will be implemented in some of 2.x
* releases
* Several smaller fixes and improvements, including defaulting
* exceptions to true, instead of false, as of this version
* An up-to-date and complete Postscript version of documentation is
* included in this distribution
* Large chunks of this manual are changed, as well as README and
* TODO files.
1.6 (Feb 3 2000) Sinisa Milivojevic <sinisa@mysql.com>
* This is a major release as it includes new features and major
* rewrites
* Automatic quoting and escaping with streams. It works
* automatically , depending on the column type. It will work with <<
* on all ostream derived types. it is paricularly handy with query
* objects and strstreams. Automatic quoting and escaping on cout,
* cerr and clog stream objects is intentionally left out, as quoting
* / escaping on those stream objects is not necessary. This feature
* can be turned of by setting global boolean dont_quote_auto to
* true.
* Made some major changes in code, so that now execute method should
* be used only with SSQL and template queries, while for all other
* query execution of UPDATE's, INSERT's, DELETE's, new method exec()
* should be used. It is also faster.
* New method get_string is inroduced for easier handling / casting
* ColData into C++ strings.
* Major rewrite of entire code, which led to it's reduction and
* speed improvement. This also led to removal of several source
* files.
* Handling of binary data is introduced. No application program
* changes are required. One of new example programs demonstrates
* handling of binary data
* Three new example programs have been written and thoroughly
* tested. Their intention is to solve some problems addressed by
* MySQL users.
* Thorough changes is Makefile system has been made
* Better configuration scripts are written, thanks to D.Hawkins
* <dhawkins@cdrgts.com>
* Added several bug fixes
* Changed Manual and Changelog
1.5 (Dec 1 1999) Sinisa Milivojevic <sinisa@mysql.com>

* Fixed bug in store and storein methods
* Fixed one serious memory leak
* Fixed a very serious bug generated by gcc 2.95.xx !!
* Added robustness in classes, so that e.g. same query and row
* objects can be re-used
* Changed sinisa_ex example to reflect and demonstrate this
* stability
* Changed Changelog and README
* Few other bug fixes and small improvements and speed-ups
1.3 (Nov 10 1999) Sinisa Milivojevic <sinisa@mysql.com>
* Fixed several erronous definitions
* Further changed source to be 2.95.2 compatible
* Expunged unused statements, especially dubious ones, like use of
* pointer_tracker
* Corrected bug in example file fieldinf1
* Finally fixed mysql_init in Connection constructor, which provided
* much greater stability !
* Added read and get options, so that clients, like mysqlgui can use
* it
* Changed Changelog and README
* Many other bug fixes.
1.2 (Oct 15 1999) Sinisa Milivojevic <sinisa@mysql.com>
* First offical release. Version 1.0 and 1.1 were releases by Sinisa
* before I (Kevin Atkinson) made him the offical maintainer,
* Many manual fixes.
* Changed README and Changelog
* Changed source to be compilable by gcc 2.95.xx, tribute to Kevin
* Atkinson <kevinatk@home.com>
* Added methods in Connection class which are necessary for
* fullfilling administrative functions with MySQL
* Added many bug fixes in code pertaining to missing class
* initializers , as notified by Michael Rendell <michael@cs.mun.ca>
* Sinisa Milivojevic <sinisa@mysql.com> is now the offical
* maintainer.
1.1 (Aug 2 1999) Sinisa Milivojevic <sinisa@mysql.com>
* Added several bug fixes
* Fixed memory leak problems and variables overlapping problems.
* Added automake and autoconf support by loic@ceic.com
* Added Makefile for manual
* Added support for cygwin
* Added example sinisa_ex (let modesty prevail) which used to crash
* a lot when memory allocation, memory leak and overlap problems
* were present. Smooth running of this example proves that all those
* bugs are fixed
* Corrected bugs in sql_query.cc regarding delete versus delete[]
* and string length in manip.cc
* Changed manual
* Changed README
* Many other smaller things
1.0 (June 9 1999) Michael Widenius <monty@monty.pp.sci.fi>
* Added patches from Orion Poplawski <orion@bvt.com> to support the
* UnixWare 7.0 compiler
.64.1.1a (Sep 27 1998)
* Fixed several bugs that caused my library to fail to compile with
* egcs 1.1. Hopefully it will still compile with egcs 1.0 however I
* have not been able to test it with egcs 1.0.
* Removed some problem causing debug output in sql++pretty.
.64.1a (Aug 1 1998)
* Added an (almost) full guide to using Template Queries.
* Fixed it so the SQLQuery will throw an exception when all the
* template parameters are not provided.
* Proofread and speedchecked the manual (it really needed it).
* Other minor document fixes.
.64.0.1a (July 31 1998)
* Reworked the Class Reference section a bit.
* Minor document fixes
* Added more examples for SSQLS.
* Changed the syntax of equal_list for SSQLS from equal_list (cchar
* *, Manip, cchar *) to (cchar *, cchar *, Manip).
* Added set methods to SSQLS. These new methods do the same thing as
* there corresponding constructors.
* Added methods for creating a mysql_type_info from a C++ type_info.
.64.a (July 24 1998)
* Changed the names of all the classes so they no longer have to
* have Mysql in the begging of it. However if this creates a problem
* you can define a macro to only use the old names instead.
* The Specialized SQL Structures (formally known as Custom Mysql
* Structures) changed from mysql_ to sql_.
* Added the option of using exceptions thoughout the API.
* ColData (formally known as MysqlStrings) will now throw an
* exception if there is a problem in the conversion.
* Added a null adapter.
* Added Mutable Result Sets
* Added a very basic runtime type identification for SQL types
* Changed the document format from POD to LYX .
* Am now using a modified version of Perceps to extract the class
* information directly from the code to make my life easier.
* Added an option of defining a macro to avoid using the automatic
* conversion with binary operators.
* Other small fixed I probully forgot to mentune.
.63.1.a
* Added Custom Mysql Structures.
* Fixed the Copy constructor of class Mysql
* Started adding code so that class Mysql lets it children now when
* it is leaving
* Attempted to compile it into a library but still need help. As
* default it will compile as a regular program.
* Other small fixes.
.62.a (May 3 1998)
* Added Template Queries
* Created s separate SQLQuery object that is independent of an SQL
* connection.
* You no longer have to import the data for the test program as the
* program creates the database and tables it needs.
* Many small bug fixes.
.61.1.a (April 28 1998)
* Cleaned up the example code in test.cc and included it in the
* manual.
* Added an interface layout plan to the manual.
* Added a reverse iterator.
* Fixed a bug with row.hh (It wasn't being included because of a
* typo).
.61.0.a
* Major interface changes. I warned you that the interface may
* change while it is in pre-alpha state and I wasn't kidding.
* Created a new and Separate Query Object. You can no longer execute
* queries from the Mysql object instead you have to create a query
* object with Mysql::query() and use it to execute queries.
* Added the comparison operators to MysqlDate, MysqlTime and
* MysqlDateTime. Fixed a few bugs in the MysqlDate... that effected
* the stream output and the conversion of them to strings.
* Reflected the MysqlDate... changes in the manual.
* Added a new MysqlSet object and a bunch of functions for working
* with mysql set strings.
.60.3a (April 24 1998)
* Changed strtoq and strtouq to strtoll and strtull for metter
* compatibility Minor Manual fix.
* Changed makefile to make it more compatible with Solaris (Thanks
* Chris H)
* Fixed bug in comparison functions so that they would compare in he
* right direction.
* Added some items to the to do list be sure to have a look.
