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:
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 J眉rgen 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...
