Doc Text:
Previously it was possible to unload static modules. As these modules are static it wasn't actually unloaded but it was only made unavailable. After the unload action was completed these modules can be reactivated only by irssi restart. It is odd behaviour, thus the unload action was blocked on the static modules. Now only the dynamic modules can be unloaded.

Description Flags
Patch for disabling unload of static modules from UI none

Description Miroslav Vadkerti 2010-10-01 09:26:09 UTC 
Description of problem:
In the latest irssi in RHEL6 i cannot reload any module after I unloaded it. When I restart irssi some modules ate auto-loaded. Unloading any module has no affect on my irssi perl scripts though (what is strange)

Version-Release number of selected component (if applicable):
irssi-0.8.15-3.el6

How reproducible:
100%

Steps to Reproduce:
1. start irssi
2. check loaded modules
/load
Module               Type    Submodules
core                 static  core irc fe fe-irc fe-text
dcc                  static  irc fe-irc
flood                static  irc
notifylist           static  irc fe-irc
perl                 static  core fe
3. unload module (e.g. perl)
/unload perl
4. verify perl module is gone
/load
Module               Type    Submodules
core                 static  core irc fe fe-irc fe-text
dcc                  static  irc fe-irc
flood                static  irc
notifylist           static  irc fe-irc
5. try to load module back
/load perl
-!- Irssi: Error loading module perl/core: /usr/lib64/irssi/modules/libperl_core.so: cannot open shared object file: No such file or directory
  
Actual results:
Can't load module

Expected results:
Module can be reloaded

Patch for disabling unload of static modules from UI

This is one of possible solutions. Other (probably better and of course harder)
solution is adding support for static modules reloading.

Seems that static modules can not be unloaded thus the patch proposed in comment 1 should be enough.
Comment 5 Suzanne Logcher 2011-02-15 21:43:21 UTC 
This issue was proposed for RHEL 6.1 FasTrack but did not get resolved in time.
It has been moved to RHEL 6.2 FasTrack.
