Description:
http://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html does not document have_community_features (and in fact, according to both the site search and a Google search of dev.mysql.com (http://www.google.com/search?q=site%3Adev.mysql.com+have_community_features ).

This feature should be documented, even if it's documented as "unused".

I've posted a short article about this at <A HREF=http://www.pythian.com/news/2333/i-apparently-have_community_features>http://www.pythian.com/news/2333/i-apparently-have_community_features</A>

How to repeat:
SHOW GLOBAL VARIABLES LIKE 'have_community_features';

Go to http://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html and view the lack of documentation.

Suggested fix:
Document the feature.

Thank you for the report.

Verified as described.

shouldn't we just remove it ?

If we want to have profiling optional, 'have_profiling' would be a more appropriate name anyway (and Sheeri would know what it means without asking :)

      Bug #44651 "have_community_features" variable should be renamed 
                 "have_profiling"
      
      1) Renamed have_community_features server system variable to have_profiling.
      2) Removed eable-community-features configure option and ENABLE_COMMUNITY_FEATURES macro.
      3) Removed COMMUNITY_SERVER macro and replaced its usage by ENABLED_PROFILING .

Pushed into 5.4.4-alpha (revid:alik@sun.com-20090617073019-azsawauatv99124t) (version source revid:jon.hauglid@sun.com-20090610075529-2au37kus25i0s7rb) (merge vers: 5.4.4-alpha) (pib:11)

Noted in 5.4.4 changelog.

The have_community_features system variable was renamed to
have_profiling.

Previously, to enable profiling, it was necessary to run configure
with the --enable-community-features and --enable-profiling options.
Now only --enable-profiling is needed.

Noted in 5.4.2 changelog because next 5.4 version will be 5.4.2 and not 5.4.4.

Ignore previous comment about 5.4.2.

      3) Removed COMMUNITY_SERVER macro and replaced its usage by 
      ENABLED_PROFILING.
      
      Only --enable-profiling is now needed to enable profiling.
      It was the only existing "community feature", so there was
      no need for both configure options.
      
      Using --enable-community-features will give a warning message
      since it no longer exists.
