safe_process puts its children (mysqld, in this case) into a separate
process group, to be able to kill it all at once.
buildslave kills mtr's process group when it loses connection to
the master.
result? buildslave kills mtr and safe_process, but leaves stale
mysqld processes in their own process groups.
fix: put safe_process itself into a separate process group, then
buildslave won't kill it and safe_process will kill mysqld'd
and itself when it will notice that the parent mtr no longer exists.
Added --mysqld-env option, propagate via safe_process
Simplified: should be safe to set in parent safe_process after it's started
Addendum: catch cases of --mysqld-env w/o value, assume env.var
name never begins with "--"
- Removed SCCS rule from Makefile.am
- Made dummy rule in sql_yacc.yy to get rid of compiler warning about not used label.
Don't use maintainer mode with valgrind (as we don't want to initialize all variables)
config/ac-macros/maintainer.m4:
Don't use maintainer mode with valgrind (as we don't want to initialize all variables)
Force initialization of variables when using -Werror (To get rid of compiler warnings)
configure.in:
Don't use maintainer mode with valgrind (as we don't want to initialize all variables)
sql/sql_yacc.yy:
Made dummy rule in sql_yacc.yy to get rid of compiler warning about not used label.
The autotools-based build system has been superseded and
is being removed in order to ease the maintenance burden on
developers tweaking and maintaining the build system.
In order to support tools that need to extract the server
version, a new file that (only) contains the server version,
called VERSION, is introduced. The file contents are human
and machine-readable. The format is:
MYSQL_VERSION_MAJOR=5
MYSQL_VERSION_MINOR=5
MYSQL_VERSION_PATCH=8
MYSQL_VERSION_EXTRA=-rc
The CMake based version extraction in cmake/mysql_version.cmake
is changed to extract the version from this file. The configure
to CMake wrapper is retained for backwards compatibility and to
support the BUILD/ scripts. Also, a new a makefile target
show-dist-name that prints the server version is introduced.
VERSION:
Add top-level version file.
cmake/mysql_version.cmake:
Get version information from the top-level VERSION file.
Do not cache the version components (MAJOR_VERSION, etc).
Add MYSQL_RPM_VERSION as a replacement for MYSQL_U_SCORE_VERSION.
- Changed to still use bcmp() in certain cases becasue
- Faster for short unaligneed strings than memcmp()
- Bettern when using valgrind
- Changed to use my_sprintf() instead of sprintf() to get higher portability for old systems
- Changed code to use MariaDB version of select->skip_record()
- Removed -%::SCCS/s.% from Makefile.am:s to remove automake warnings
Apart strict-aliasing warnings, fix the remaining warnings
generated by GCC 4.4.4 -Wall and -Wextra flags.
One major source of warnings was the in-house function my_bcmp
which (unconventionally) took pointers to unsigned characters
as the byte sequences to be compared. Since my_bcmp and bcmp
are deprecated functions whose only difference with memcmp is
the return value, every use of the function is replaced with
memcmp as the special return value wasn't actually being used
by any caller.
There were also various other warnings, mostly due to type
mismatches, missing return values, missing prototypes, dead
code (unreachable) and ignored return values.
BUILD/SETUP.sh:
Remove flags that are implied by -Wall and -Wextra.
Do not warn about unused parameters in C++.
BUILD/check-cpu:
Print only the compiler version instead of verbose banner.
Although the option is gcc specific, the check was only
being used for GCC specific checks anyway.
client/mysql.cc:
bcmp is no longer defined.
client/mysqltest.cc:
Pass a string to function expecting a format string.
Replace use of bcmp with memcmp.

Use appropriate type.
extra/replace.c:
Replace use of bcmp with memcmp.
extra/yassl/src/crypto_wrapper.cpp:
Do not ignore the return value of fgets. Retrieve the file
position if fgets succeed -- if it fails, the function will
bail out and return a error.
extra/yassl/taocrypt/include/blowfish.hpp:
Use a single array instead of accessing positions of the sbox_
through a subscript to pbox_.
extra/yassl/taocrypt/include/runtime.hpp:

extra/yassl/taocrypt/src/blowfish.cpp:
Avoid potentially ambiguous conditions.
extra/yassl/taocrypt/src/integer.cpp:
Do not define type within a anonymous union.
Use a variable to return a value instead of
leaving the result in a register -- compiler
does not know the logic inside the asm.

Define handler for pure virtual functions.
Remove unused code.
extra/yassl/taocrypt/src/twofish.cpp:
Avoid potentially ambiguous conditions.
extra/yassl/testsuite/test.hpp:
Function must have C language linkage.
include/m_string.h:

Remove bogus helpers which were used only in a few files and
were causing warnings about dead code.

Replace bogus helpers with simple and classic bit operations.
sql/slave.cc:
Cast to expected type and silence bogus warning.
sql/sql_class.h:
Don't use enum values as bit flags, the supposed type safety is
bogus as the combined bit flags are not a value in the enumeration.

Only declare variable when necessary.
sql/unireg.h:
Replace use of bmove_align with memcpy.
storage/innobase/os/os0file.c:

Use a appropriate type as expected by simple_command().
(make relies GNU extentions). The patch was partially
backport from 6.0.
Original comment:
bug#30708: make relies GNU extensions. Now that we no longer use
BitKeeper we can safely remove the SCCS handling with no loss of
functionality.

Corrected some packaging bugs:
- install mysqlservices library
- install libmysqlclient_r.so.{16,16.0.0} as links
to libmysqlclient.so
- install libmysqld-debug.a
- install my_safe_process, my_safe_kill and
symlinks to mysql-test-run.pl (mtr, mysql-test-run)
into correct place ${INSTALL_MYSQLTESTDIR}
cmake/install_layout.cmake:
Fix typo
cmake/install_macros.cmake:
Refactor INSTALL_SYMLINK to allow arbitrary symlink paths.
Old version of this macro would make link extension the same
as in target. This was not sufficient in some scenarios
(would not allow for example libmysqlclient_r.so.16=>./libmysqlclient.so
link)
libmysql/CMakeLists.txt:
Install extra symlinks to libmysqlclient.so
(libmysqlclient_r.so.16 and libmysqlclient_r.so.16.0.0)
for backward compatiblity.
libmysqld/CMakeLists.txt:
install libmysqld-debug.a
libservices/CMakeLists.txt:
install mysqlservices library
mysql-test/lib/My/SafeProcess/CMakeLists.txt:
install my_safe_process, my_safe_kill into correct place
using cmake option INSTALL_LAYOUT=STANDALONE would produce the layout as in
tar.gz or zip packages.
INSTALL_LAYOUT=UNIX will produce unixish install layout (with mysqld being in sbin subdirectory , libs in lib/mysql etc). This layout is used for RPM packages.
Subtle differences in both packages unfortunately lead to the need to recompile MySQL to use with other package type - as otherwise for example default plugins or data directories would be wrong set.
There are numerous other variables that allow fine-tuning packaging layout. (INSTALL_BINDIR, INSTALL_LIBDIR , INSTALL_PLUGINDIR etc).
This options are different from autotools as they do not expect full paths to directories, but only subdirectory of CMAKE_INSTALL_PREFIX.
There are 2 special options that expect full directory paths
- MYSQL_DATADIR that defines default MYSQL data directory (autotools equivalent
is --localstatedir)
- SYSCONFDIR can be added to search my.cnf search path (autotools equivalent is --sysconfdir)
- The arguments are properly quoted when mtr.pl calls my_safe_process but
unfortunately the all off when running with active state perl and stays
in cygwin perl.
- Extend the patch to only quote args that are not already quoted
This a redo of previous commit, will be included in next push
