Bug #58597	CMake does not set -DWITH_EXTRA_CHARSETS=complex for mysql_release

Description:
http://dev.mysql.com/doc/refman/5.1/en/cannot-initialize-character-set.html says:

"All standard MySQL binaries are compiled with --with-extra-charsets=complex, which enables support for all multi-byte character sets."

That applies to autotools-configured MySQL releases.

For CMake in 5.5+, it seems that WITH_EXTRA_CHARSETS is set to "all", not "complex". The default for this option is "all" and it is not changed by  -DBUILD_CONFIG=mysql_release.

How to repeat:
cmake . -DBUILD_CONFIG=mysql_release

Then observe that WITH_EXTRA_CHARSETS is still "all" (for example, use ccmake .)

Suggested fix:
Build releases with "complex" if it's supposed to be the same with CMake as with autotools.

Thank you for the report.

Verified as described.

triage: setting tag to SR55MRU (do be done in the lifetime of 5.5)

5.1 manual was wrong in this regard. On Windows, all charsets were always compiled in, and "all" is more than "complex".

What is the default behavior supposed to be for CMake? Do we have a bug here?

Build team: Is Wlad's comment of [13 Jan 14:47] also true for 5.0?

Paul, on Windows all charsets were always compiled in, also in 5.0. There was no way to restrict charsets. I thought default=all is hence a good default, couple of extra charsets will not not hurt, right?

I am recategorizing this as a docs bug and updating the page in question to note that Windows binaries before 5.5 are configured with "=all", and all binaries in 5.5 are configured with "=a".

Thank you for your bug report. This issue has been addressed in the documentation. The updated documentation will appear on our website shortly, and will be included in the next release of the relevant products.
