MySQL Bugs: #34983: List enabled plugins after a ./configure run

Bug #34983	List enabled plugins after a ./configure run
Submitted:	2 Mar 2008 13:31	Modified:	25 Oct 2018 6:36

Status:	Won't fix	Impact on me:	None
Category:	MySQL Server: Compiling	Severity:	S4 (Feature request)
Version:	5.1.23a-maria	OS:	Any
Assigned to:		CPU Architecture:	Any

Description:
Please list which plugins whould be build after a configure run.

MPlayer does this and it makes it much easier to see if all required plugins are configured in. I like to find out missing compile options before the actual compile.

This should also list if ndbcluster is enabled. ndbcluster is not build even when the "--with-plugins=all" option is used, this is not very obvious. It requires the --enable-ndbcluster option.

How to repeat:
./configure

Suggested fix:
Something like this (although this won't list disabled plugins):
awk '/WITH_.*_STORAGE_ENGINE/ { engine=substr($2,6); engine=substr(engine,1,index(engine,"_")-1); if ($3 == "1") { print "Storage engine " engine " is enabled." } else { "Storage engine " engine " is not enabled" }}' config.log

Many thanks for writing a feature request.

Thanks for your feature request, i think this would perfectly make sense and have verified it as valid bug entry.

A little more background on this

This is how the MPlayer output looks like

[...]

It would indeed be nice if the MySQL configure output looked similar (constructed example, not necessarily complete):

  Enabled optional plugins:
    Storage engines: innodb 
    Information schema: show_variables, show_status
    [...]
  Disabled optional plugins:
    Storage engines: ndb
    Information schema: show_master_status, show_slave_status

It may not be possible to categorize this by plugin type though
as one plugin project can actually contain multiple plugins, e.g.
ndb (when it becomes fully pluggable) would provide both the
ndb storage engine plugin and ndb specific information_schema plugins.

Would the recent switch with 5.5 from autotools to cmake make this any easier?

Since MySQL now uses CMake, this information can be found in CMakeCache.txt after the cmake run.
