--- Comment #1 from Milian Wolff <mail milianw de>  2011-11-23 22:35:24 ---
note that this was much easier to reproduce until recently, no it got better
but I still encounter this error from time to time. Now with bug 286045 fixed I
see this error message in such cases:

Unknown error. (Unable to fetch item from backend)

this was also confirmed by antlarr in #kontact irc today, but not real solution
was found, nor an easy way to trigger it. here is the irc log for the record:

[20:27] <antlarr> [16:21:43] andris, milian : about the problem with
"retrieving folder contents. Please wait"... I got it again
[20:27] <antlarr> [16:21:59]  akonadiconsole shows the agent is online, idle
[20:27] <milian> [16:22:03] antlarr: please open akonadiconsole, what do you
see there - errors ?
[20:27] <milian> [16:22:04] ah hm
[20:27] <andris> [16:22:14] hm
[20:27] <krop> [16:22:23] allen_kdab: you can define a local gitignore file if
you want (for repos without .gitignore)
[20:27] <antlarr> [16:22:24] I just enabled the debugger now
[20:27] <antlarr> [16:22:45] should I enable "job tracker", etc ?
[20:27] <antlarr> [16:23:09] do you want me to put the agent offline/online ?
[20:27] <antlarr> [16:23:14] gdb any process ?
[20:27] <andris> [16:23:52] manny things could be tried
[20:27] <allen_kdab> [16:23:56] krop: yes but I figured since the repo's
.gitignore already had .kdev stuff, then 
[20:27] <antlarr> [16:24:00] andris: :)
[20:27] <antlarr> [16:24:07] andris: tell me :)
[20:27] <andris> [16:24:09] enable the debugger (not the job tracker) is one
[20:27] <andris> [16:24:22] gdb-ing the akonadi_imap_resource or the
akonadiserver is another

[20:27] <antlarr> [16:24:44] I'm getting those in akonadi's debugger
[20:27] <allen_kdab> [16:24:53] krop: do you want me to remove that entry from
the repo's .gitignore?
[20:27] <andris> [16:25:03] it tells the error, just not the reason
[20:27] <krop> [16:25:04] no no, that's fine 
[20:27] <andris> [16:25:57] antlarr: sec, i need to load kdepim into kdevelop
[20:27] <antlarr> [16:26:13] each 20 seconds or so I get a couple more lines
(if you want better timings, tell me)
[20:27] <andris> [16:26:37] are those also fetch comand with the same error
response?
[20:27] <antlarr> [16:26:44] btw
[20:27] <antlarr> [16:26:49] each ID fetched is tried twice
[20:27] <antlarr> [16:27:10] andris: yes
[20:27] <antlarr> [16:27:17] always the same error response
[20:27] <antlarr> [16:27:26] (with different sequence ID, of course :) )
[20:27] <andris> [16:27:26] try to gdb into akonadi_imap_resource
[20:27] <andris> [16:27:30] and see what it does
[20:27] <antlarr> [16:28:06] it has two threads
[20:27] <antlarr> [16:28:32] one of them is in
QEventDispatcherGlib::processEvents
[20:27] <antlarr> [16:28:50] and the other too
[20:27] <antlarr> [16:29:02] (in fact, in a poll system call)
[20:27] <andris> [16:29:24] do you have a debug build for kdepim-runtime?
[20:27] <antlarr> [16:30:25] nop, I'm at work here :(
[20:27] <antlarr> [16:30:39] I'm installing now the -dbg package and I'll see
if I can use it
[20:27] <antlarr> [16:30:52] (I'm using kubuntu here)
[20:27] <andris> [16:30:58] i'm not sure it helps if you already have the app
running

[20:27] <CIA-5> [16:31:02] Get rid of the FindGit.cmake copy.

[20:27] <andris> [16:31:07] the idea would be to debug into the resource why it
fails
[20:27] <andris> [16:31:15] I could give some hints where to put breakpoints
[20:27] <andris> [16:32:52] also (in  the future) try to enable the debug area
for akonadi_imap_resource and start akonadiserver from a console (akonadictl
start) maybe we can learn something extra from the debug outputs
[20:27] <andris> [16:33:12] be sure to disable the debugger in akonadiconsole
when you don't need, it will make things much slower
[20:27] <antlarr> [16:34:20] Reading symbols from
/usr/bin/akonadi_imap_resource...Reading symbols from
/usr/lib/debug/usr/bin/akonadi_imap_resource...done.
[20:27] <antlarr> [16:34:30] yep, it works with a running app :)
[20:27] <andris> [16:35:14] try a breakpoint in ImapResource::retrieveItem and
see if it is hit
[20:27] <antlarr> [16:37:36] btw, this is a kolab server and I saw there's a
akonadi_kolabproxy_resource app running too, I guess akonadi_imap_resource is
the right one anyway, right?
[20:27] <antlarr> [16:37:59] it's not stopping at that method
[20:27] <antlarr> [16:38:12] I saw some more fetches in the debugger
[20:27] <andris> [16:38:19] yes, the imap resource is the right one
[20:27] <antlarr> [16:38:24] since I put the breakpoint
[20:27] <andris> [16:38:40] hm, ervin would be your real man for imap
debugging...
[20:27] <andris> [16:39:03] he is online on #akonadi, maybe you can ask some
hints where to put the breakpoint
[20:27] <andris> [16:39:33] i was expecting that you hit that method
[20:27] <antlarr> [16:42:14] well, the name seems promising...
[20:27] <CIA-5> [16:43:05] Montel Laurent master * v4.7.0-1768-g1b41d21
[kdepim] / (kmail/kmreadermainwin.cpp messageviewer/viewer_p.cpp) 
[20:27] <CIA-5> [16:43:05] Now we can copy embedded item in an other folder.

[20:27] <antlarr> [16:44:14] gdb told me that method was at
../../../resources/imap/imapresource.cpp, line 262 so I put a breakpoint on
260, 261, 262, 263 ... up to 269 :)
[20:27] <antlarr> [16:44:19] and nothing
[20:27] <andris> [16:44:32] another hint
[20:27] <andris> [16:44:48] now gdb akonadiserver
[20:27] <andris> [16:45:43] and break at bool ItemRetriever::exec()
[20:27] <antlarr> [16:45:57] wow, 26 threads :)
[20:27] <andris> [16:46:11] yeah, akonadi *is* multitheaded :)
[20:27] <andris> [16:46:20] guess why sqlite doesn't like it
[20:27] <antlarr> [16:47:37] Function "ItemRetriever::exec" not defined
[20:27] <antlarr> [16:48:08] I'm installing more -dbg packages
[20:27] <antlarr> [16:49:55] nope, I installed also akonadi-dbg and it still
tells me ItemRetriever::exec is not defined
[20:27] <antlarr> [16:50:10] in which library should that be defined?
[20:27] <andris> [16:51:29] it is inside akonadiserver, not a lib
[20:27] <kde-ci-bot> [16:54:05] Project kdepim_master build #790: STILL
UNSTABLE in 9 min 42 sec: http://build.kde.org/job/kdepim_master/790/
[20:27] <kde-ci-bot> [16:54:05] * cgiboudeaux: Get rid of the FindGit.cmake
copy.
[20:27] <kde-ci-bot> [16:54:06] * montel: Now we can copy embedded item in an
other folder.
[20:27] <antlarr> [16:54:08] ops
[20:27] <antlarr> [16:54:20] andris: I guess kubuntu packages are stripped
[20:27] <andris> [16:54:50] aren't there an akonadiserver-dbg?
[20:27] <antlarr> [16:56:58] aah
[20:27] <antlarr> [16:57:03] maybe it's inside a namespace ?
[20:27] <andris> [16:57:17] namespace Akonadi indeed
[20:27] <antlarr> [16:59:45] now :)
