'mysql_config --libs' outputs -L/path/to/library
on SunOS we also want it to output '-R/path/to/library'
in order to find libraries at runtime.
cmake/libutils.cmake:
Add an informational message, to show dependencies on OS libraries.
Essentially, the problem is that safemalloc is excruciatingly
slow as it checks all allocated blocks for overrun at each
memory management primitive, yielding a almost exponential
slowdown for the memory management functions (malloc, realloc,
free). The overrun check basically consists of verifying some
bytes of a block for certain magic keys, which catches some
simple forms of overrun. Another minor problem is violation
of aliasing rules and that its own internal list of blocks
is prone to corruption.
Another issue with safemalloc is rather the maintenance cost
as the tool has a significant impact on the server code.
Given the magnitude of memory debuggers available nowadays,
especially those that are provided with the platform malloc
implementation, maintenance of a in-house and largely obsolete
memory debugger becomes a burden that is not worth the effort
due to its slowness and lack of support for detecting more
common forms of heap corruption.
Since there are third-party tools that can provide the same
functionality at a lower or comparable performance cost, the
solution is to simply remove safemalloc. Third-party tools
can provide the same functionality at a lower or comparable
performance cost.
The removal of safemalloc also allows a simplification of the
malloc wrappers, removing quite a bit of kludge: redefinition
of my_malloc, my_free and the removal of the unused second
argument of my_free. Since free() always check whether the
supplied pointer is null, redudant checks are also removed.
Also, this patch adds unit testing for my_malloc and moves
my_realloc implementation into the same file as the other
memory allocation primitives.
client/mysqldump.c:
Pass my_free directly as its signature is compatible with the
callback type -- which wasn't the case for free_table_ent.
Unresolved reference to 'innodb_system_libs' in "mysql_config"
In 5.4.2, we use InnoDB 1.0.4 which does file IO via separate
threads, opposed to the use of asynchronous IO previously.
So there is no InnoDB call to "aio_read()" which was searched
in "librt", causing a "-lrt" value of "innodb_system_libs",
that whole variable is gone.
This fix was applied in the build of 5.4.2-beta.
scripts/Makefile.am:
There is no "innodb_system_libs" variable any more,
so it cannot be replaced by its value.
scripts/mysql_config.pl.in:
InnoDB does not need any platform-specific libraries any more,
"innodb_system_libs" may go.
scripts/mysql_config.sh:
InnoDB does not need any platform-specific libraries any more,
"innodb_system_libs" may go.
mysql_config did not output -ldl (or equivalent) when needed for --libmysqld-libs,
so its output could be insufficient to build an application using the embedded
server.
LIBDL was already set in configure; it's now propagated all the way into the
relevant mysql_config scripts.
scripts/Makefile.am:
We "manually" replace configure's constants in .sh scripts using sed,
so AC_SUBST() alone is not good enough. Add LIBDL to the substitution
list; we'll be needing it for mysql_config --libmysqld-libs
scripts/mysql_config.pl.in:
Add LIBDL (usually -ldl) to output of mysql_config --libmysqld-libs (perl version)
scripts/mysql_config.sh:
Add LIBDL (usually -ldl) to output of mysql_config --libmysqld-libs (shell version)
Better Windows support in the scripts directory
mysql_config.pl.in, mysql_install_db.pl.in:
New Perl version of Unix shell script, mainly for Windows
Many files in scripts directory:
Use default Perl location "#!/usr/bin/perl" instead of the build host path
extra/CMakeLists.txt:
Added target for executable "resolveip"
extra/resolveip.c:
Exclude Unix specific headers when compiling on Windows
scripts/CMakeLists.txt:
On Windows, filter Perl scripts and change name from ".sh" to ".pl"
mysql_convert_table_format.sh mysql_explain_log.sh
mysql_secure_installation.sh mysql_tableinfo.sh
mysqld_multi.sh mysqldumpslow.sh
mysqlhotcopy.sh
Do the same for the new Windows specific Perl versions of shell scripts
mysql_config.pl.in mysql_install_db.pl.in
In CMake, set reasonable values for 'CFLAGS', 'prefix', 'datadir' and so on.
scripts/Makefile.am:
Include "mysql_config.pl.in" and "mysql_install_db.pl.in" in the source TAR
scripts/make_win_bin_dist:
Only include explicitly listed scripts from the "scripts" directory
scripts/mysql_convert_table_format.sh:
Use default Perl location "#!/usr/bin/perl" instead of the build host path
scripts/mysql_explain_log.sh:
Use default Perl location "#!/usr/bin/perl" instead of the build host path
scripts/mysql_tableinfo.sh:
Use default Perl location "#!/usr/bin/perl" instead of the build host path
scripts/mysqld_multi.sh:
Use default Perl location "#!/usr/bin/perl" instead of the build host path
scripts/mysqldumpslow.sh:
Use default Perl location "#!/usr/bin/perl" instead of the build host path
scripts/mysqlhotcopy.sh:
Use default Perl location "#!/usr/bin/perl" instead of the build host path
scripts/mysql_config.pl.in:
New Perl version of Unix shell script, mainly for Windows
scripts/mysql_install_db.pl.in:
New Perl version of Unix shell script, mainly for Windows
