The build scripts in general, using automake, autoconf, etc, contain several
special commands and work around all related to the way the bison code in the
parser is built, for sql/sql_yacc.yy. These work arounds, accumulated over
time during development, ultimately cause the build scripts to be unstable
and cause build defects by not enforcing dependencies.
This fix simplifies the build process and aligns it with the automake tooling,
which provides native support for bison and *.yy files.
In particular, the following problem have been fixed:
- dependencies with sql_yacc.cc were not honored (Bug 21029), leading to
corrupted builds,
- the work around introduced by Bug 24557, to cleanup the generated files
sql_yacc.h and sql_yacc.cc, has been removed,
- the generated makefile, in a source distribution, used to destroy the files
sql_yacc.h and sql_yacc.cc on a 'make clean' target. This has been fixed:
these files are now removed by make maintainer-clean.
- The root cause of the problem found with gcc 4.1 (see Bug 24619) has been
clearly documented, and the "sed" hack has been replaced by a cleaner
work around, when building the code with bison 1.875.
- Removed the file sql/sql_yacc.yy.bak, added by WL 3031 by accident.
- Removed the unnecessary AM_YFLAG= --debug introduced by WL 3432, since
the compiling option DBUG_OFF takes precedence when setting YYDEBUG.

- test* targets are identical (as much as possible) to 5.0 & 5.1 versions
- use @PERL@ ./mysql-test-run.pl, instead of depending on /usr/bin/perl location
- PHONY: target includes all test targets
If --srcdir and --windows is given, check if error message file
is in source or build tree (bug#24557)
Makefile.am:
Cleaned up "ali_check" target, to satisfy "distcleancheck" (bug#24557)
mysql_install_db.sh:
Added --srcdir=DIR option, used from top Makefile.am in dist-hook
target, to find "fill_help_tables.sql" in VPATH build (bug#24557)
Makefile.am:
Work around problem with "distcleancheck", "sql_yacc.cc" might be in both
the source and build tree.
Call "mysql_install_db" with new option --srcdir, to enable the script
to find all that is needed, if source and build directory is not the same
(bug#24557)
Fixed memory leak in _db_set() (Bug#24497 Valgrind warning: get_one_option)
Don't call net_clear() on COM_QUIT. This avoids a warning from net_clear() after shutdown: "skipped ## bytes from file"
BUG#21428: skipped 9 bytes from file: socket (3)" on "mysqladmin shutdown"
for push in 5.1 (I will inform Trudy).
Storage engines and plugins can now have unit tests to test their components; such
test must be an executable C/C++ program which name ends with '-t' and which is
obeys the mytap protocol, it must be stored in the storage engine's or plugin's
source directory (storage/<engine> or plugin/<plugin>) or any subdirectories of
this.
The top-level Makefile target "test-unit" will run all unit tests: it will scan
the engines' and plugins' directories, recursively, and execute all executable
files which name ends with '-t'."
