Item9841: Plugin installation fails due to broken extender.pl

Priority:	CurrentState:	AppliesTo:	Component:	WaitingFor:
Normal	Closed	Engine	extender.pl

Plugin installation on the commandline fails if LocalSite.cfg contains empty lines or $Foswiki::cfg{ScriptDir} uses double quotes. Running any Plugin installer throws the error 'There was a compile error: Can't locate setlib.cfg in @INC'.

This is due to a bug in the sub getScriptDir in extender.pl - it does not return the ScriptDir if your LocalSite.cfg has an empty line somewhere before the definition of $Foswiki::cfg{ScriptDir}, or if your LocalSite.cfg uses double quotes for the definition of $Foswiki::cfg{ScriptDir}.

Since sub getScriptDir does not return the ScriptDir, the chdir in line 101 fails. For some reason, this has no impact when using the configure webinterface - maybe it's already in the correct directory. On the commandline instead, it causes the installation to fail.

I've committed a fix for 1.1.1 - you can find the modified extender.pl at http://trac.foswiki.org/browser/branches/Release01x01/core/tools/extender.pl?rev=9605 If you have a chance to test it, please let us know. The fix works okay in my tests. Thanks for the detailed report.

Patch works for me, too.
