The autotools-based build system has been superseded and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.
- Suffix like "-m2", "-rc" becomes part of version as "_m2", "_rc".
- Release counts from 1, not 0.
This is done for both the "generic" RPMs and the "shared-compat" ones.
It includes introducing a new version variable "MYSQL_U_SCORE_VERSION"
in "configure.in", where the dash is replaced by an underscore:
5.5.1-m2 -> 5.5.1_m2
can be used to build a compatibility package that includes the shared
libraries of MySQL 3.23.xx and MySQL 4.0.xx for backwards compatibility
with dynamically linked applications. It simply repackages the two
MySQL-shared RPMs, so these need to be created or downloaded separately.
