--- 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> [16:24:25] kontact-2096466285 (0x85ee9a0) 595 UID FETCH 419471 FULLPAYLOAD ALLATTR ANCESTORS 1 EXTERNALPAYLOAD (UID REMOTEID REMOTEREVISION COLLECTIONID FLAGS SIZE DATETIME ATR:ErrorAttribute) [20:27] <antlarr> [16:24:29] kontact-2096466285 (0x85ee9a0) 595 NO Unable to fetch item from backend [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] Christophe Giboudeaux master * v4.7.0-1767-g3089dff [kdepim] / (CMakeLists.txt cmake/modules/FindGit.cmake) [20:27] <CIA-5> [16:31:02] Get rid of the FindGit.cmake copy. [20:27] <CIA-5> [16:31:02] http://commits.kde.org/kdepim/3089dff99d23e3a638c58d17bf08714b14e2e030 [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] <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] <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 :) -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Kdepim-bugs mailing list [email protected] https://mail.kde.org/mailman/listinfo/kdepim-bugs
