Description Ian 2017-01-08 07:44:02 UTC

When deleting emails from the Kmail inbox, either several (around 5+) individually, or selecting several, Kmail "hangs" with "Retrieving Folder Contents Please wait..." 

And in a terminal window, after a akonadictl restart but before deleting emails:

......

QProcess: Destroyed while process ("akonadiserver") is still running.
org.kde.pim.akonadicontrol: ProcessControl: Application "akonadiserver" stopped unexpectedly ( "Process crashed" )
org.kde.pim.akonadicontrol: Application 'akonadiserver' crashed. No restart!

I am not sure if this is related, but there are  numerous duplicated deleted emails in the Inbox - and running akonadictl fsck and akonadictl vacuum seems to do nothing. 

I can run akonadictl fsck multiple times and gives the exact came out put in regard to finding duplicate messages. It doesn't seem to actually clean up the duplicates so it does not seem to work.

Comment 1 stefanfrank 2017-01-10 19:11:11 UTC

same problem here. Manjaro with KDE Apps 16.12.
Please fix it.

Glad to know I am not the only one experiencing this. 

Kmail has basically become unusable for me. I've had to switch to Thunderbird in order to retrieve, read and reply to emails. I have been  using Kmail for many many years (since 2002) and it's unfortunate that I've had to change email app just to be able to read, reply and send emails.

Comment 3 Christoph Feck 2017-01-10 19:41:09 UTC

Could you please add a backtrace for the crash? It might be a duplicate that is already reported, or already fixed.

Not really sure how to do this - but googled. Apparently one needs to run an application with gdb? 

So - I tried that. Stopped akonadictl. Then:

gdb akonadictl start

This is what I get:

Please ask in a forum of your distribution how to install debug symbol packages.

Comment 7 stefanfrank 2017-01-13 13:35:42 UTC

I hope that helps?

Comment 8 tomaggio 2017-01-14 22:13:35 UTC

same Problem here ChakraLinux after last upgrade to 16.12.0. Sometimes it's enough try to open an mail. Retrieving mail wait. Something in the db blocks.

Comment 9 Alexander 2017-01-20 12:59:15 UTC

The description, that akonadi crashes if you delete an email is true, but it crashes randomly, independently from what you do. Click an email, it may crash or not; go to another account, same. See this bug report: 

https://bugzilla.opensuse.org/show_bug.cgi?id=1017147

Akonadi stopped working with update to 16.12 and this is more than an month ago.

Comment 10 C. Brouerius van Nidek 2017-01-20 17:33:57 UTC

Have the same problems and help myself with folloWING SOLUTION (which seems to work quit often:
 rm -rf ~/.local/share/akonadi/socket*
 rm -rf /tmp/akonadi*
and a restart of kmail

Comment 11 Gero Müller 2017-01-24 15:22:52 UTC

kcrash stacktraces after crash on akonadictl stop

Comment 12 Gero Müller 2017-01-24 15:25:46 UTC

Hello,

i have the same problem in Archlinux, akonadi 16.12.1-2, mariadb 10.1.21-1

I found the following line in ~/.local/share/akonadi/db_data/mysql.err:
  2017-01-24 14:10:07 139694250785536 [ERROR] mysqld: Deadlock found when trying to get lock; try restarting transaction

Also, if i delete the messages one after another and wait between the deletion, it does not hang. Looks like a synchronization problem.

Comment 13 Andreas K. Huettel 2017-01-30 18:15:36 UTC

Same phenomenon here as described by original submitter, here with Gentoo. 
* randomly, kmail does not delete an e-mail
* when leaving kmail and then stopping akonadi, akonadi crashes.

Comment 14 Alexander 2017-01-31 09:45:52 UTC

The bug »survived« the update to KDE Applications 16.12.1. Akonadi crashes, when I'm changing to a mailing list folder, which contains lots of emails.

Comment 15 tomaggio 2017-02-04 12:55:05 UTC

Same here; Chakra Linux with KDE Applications 16.12.1

I'm not sure if it is the same as bug 375558, but what Alexander writes suggest this assumption. The problem with deleting mails I did not notice yet. But I usually do not delete more than one mail at a time.

Comment 17 C. Brouerius van Nidek 2017-02-05 02:16:08 UTC

Found in all email folders that are regularly used that read messages where still in the new subdirectory. Since 24 hours I have removed these messages manualy (Midnight Commander) from new to cur and did not have any crash of kmail. Will report in a week :) if this is this is a temporary solution. The problem of too many duplicates receiving does not seem to be of importance for crashing. Just a nuisance.

Comment 18 Knut Hildebrandt 2017-02-05 03:21:31 UTC

(In reply to C. Brouerius van Nidek from comment #17)
> Found in all email folders that are regularly used that read messages where

Because of Bug374925 I regularly check the directories where I move or copy mails and thus can partially confirm this behaviour. All mails - read or unread - end up in the   new subdirectory and stay there. Always move them by hand. Maybe that is why I do not experience the crashes when deleting mails?

But mails that directly arrive to the inbox are moved from new to cur after being read. Once in cur no mail ever gets moved back to new, even if I mark them unread again.

Comment 19 stefanfrank 2017-02-05 14:44:05 UTC

I hope its gonna fixed very soon. Kmail is not useable!

Comment 20 Christoph Feck 2017-02-07 01:51:12 UTC

From looking at the stack trace in comment #13, it looks like Akonadi::Server::Connection still runs in thread 11, while thread 1 already deleted it.

Deleting a connection should wait until all threads that run from it are terminated.

Christoph, here: https://lists.opensuse.org/opensuse-factory/2017-02/msg00048.html is a good description, what happens. The trouble comes from filtering emails in a POP3 account.

Comment 22 Knut Hildebrandt 2017-02-08 00:44:35 UTC

(In reply to Alexander from comment #21)
> The trouble comes from filtering emails in a POP3 account.

That might explain why I do not experience the crashes while deleting mails. I only use IMAP. But there are still the problems mentioned in Comment 9 and Comment 18. Maybe these should be moved to separate bugreports.

Comment 23 Daniel Vrátil 2017-02-23 18:59:19 UTC

The crash itself has been fixed by commit https://commits.kde.org/akonadi/5219f770b998aad16a3d51bbd4f4c7ceb8b143c9 which will be in Akonadi 5.4.3 (KDE Applications 16.12.3) in March.

The patch fixes the crash itself, but does not address the underlying problem. I'll keep this opened until the underlying problem is resolved.

--- Notes for future me:
The root cause is the nested QEventLoop in ItemRetriever::exec(). When Connection is terminated (by server shutdown or connection loss on socket) while the nested QEventLoop in ItemRetriever is running, Connection::quit() will be invoked from the nested loop, destroying certain resources (socket, datastore). This then leads to various crashes once the nested event loop ends and execution within ItemRetriever::exec() continues.

I don't think it's possible to prevent nested event loop from executing metacalls on Connection, after all the main reason for using QEventLoop in ItemRetriever was to make it more interactive and interruptable. Connection::quit() cannot directly terminate the nested QEventLoop, because it has been invoked from it. It could however use delay invocation to quit the loop and return early without actually quiting and destroying the thread. The thread would quit once the excecution would return from the Handler back to Connection::slotNewData(). Connection::quit() could probably set a flag or something. However it's not clear how Connection::quit() should detect where it's invoked from and whether it's a nested QEL or not, and how it should interact with it.

Git commit 1593c17da9cbdc1483541e1e7d7630f3c91f8208 by Daniel Vrátil.
Committed on 24/02/2017 at 16:22.
Pushed by dvratil into branch 'Applications/16.12'.

Fix crash when Connection is closed while ItemRetriever is running

ItemRetriever::exec() runs a nested QEventLoop. If the parent
Connection is terminated while the event loop is running, the
delayed AkThread::quit() invocation is executed and the thread
is destroyed, while technically there is still execution going
on. To workaround that issue we don't destroy the thread in
Connection::quit() if we detect a nested QEventLoop but instead
we just notify the event loop to quit and destroy the thread
later when execution returns back to ItemRetriever::slotNewData().

This fixes a crash in QPSQLQuery, which was dereferencing a
QPSQLDriver after the driver has been deleted as the thread was
destroyed and avoids more of random crashes due to the Connection
being virtually deleted from its own nested event loop.
FIXED-IN: 5.4.3

Hi,
unfortunately the new update to Version 5.4.3 do not solve the problem. I still have crashes!
Best regards

Comment 35 Dennis Schridde 2017-03-20 13:33:15 UTC

I am using akonadi-server/xenial,now 4:16.12.3-0neon+16.04+build7 and am also still experiencing this issue. (How do I figure out the actual version number?)

Comment 36 Olivier BELLEUX 2017-03-20 13:58:03 UTC

I confirm that the update does not completely solve the bugs.

I received two mail (html newsletters) that were filtered to the right folder but then read them caused a crash; Unable to delete them from kmail; I had to do it by hand since my maildir (my accounts are all in pop3: safer) then:
Akonadi fsck
Akonadi vacuum
Akonadi restart
Kontact

Tired of this akonadi.

Akonadi is an interface between the client and the server ... but when akonadi bugs it becomes a wall between the applications of the kontact suite and servers ...

The idea was good but the implementation is far from conclusive: perhaps it is time to replace the too complex and fragile akonadi with a simpler solution such as a module kcm to centralize the management of accounts (kde -pim and telepathy) and stored these configurations in such a way that all software can access these resources directly. In addition kpart k-d-bus technologies would allow a client to access resources through another client.

Of course this implies more code and work for each client but in the end it would probably be more KISS and therefore more robust.

This does not prevent the use of databases to optimize clients, but several sqlite db may be more robust than a very large mysql db, may not ?

Sorry for my comment a bit long but these multiple and recurring Akonadi dysfunction starts to disgust me from Kontact which is the killer apps for which I chose kde instead of gnome 7 years ago.

If the situation does not evolve in the right direction then I should resolve to leave kde for gnome: it will be painful to me but if the stubbornness of the kde-pim team to keep alive akonadi persists then it will be bye bye. ..

Hi,
I also updated to 16.12.3 and it still has some issues with the filter agents as described in the previous post.
I figured out now, that filtering spams with bogofilter or spamassassin does work now, not sure whether that is new. However, adding additional filters, e.g. move all incoming mails which contain a specific string to another subfolder still leads to the problems described: doubling of mails, not able to delete mails.

I also use pop. Not sure whether that also applies to imap.

Please provide a new backtrace of the crash.


Regarding the filtering issue, there are another bug reports regarding this, please report your issue there.

Maybe my problem is exactly the filtering bug. I am using Pop3 and filters in Kmail. What is the link to that Bugreport?
To complete your request I attached the crashreport:

Application: Kontact (kontact), signal: Segmentation fault

Hi!
yes I know. But the only text that is displayed is:


--Application: Kontact (kontact), signal: Segmentation fault--


not very useful I think.

Another crash

a second crash this morning.
That could be more useful.

Comment 44 Daniel Vrátil 2017-04-07 11:59:46 UTC

The crash should be fixed in 17.04 release.

http://cgit.kde.org/akonadi.git/commit/?id=da7070a7facb3c2f91c03b28c36ba5b929b89a42

Please test against the new version and reopen if you can still reproduce the crash.

New crash Apps 17.04

New crash Apps 17.04.
I have pop3 und mailfilter active.
When I want to open an filtered mail in html format kmail/acodadi crashes.
The mail-text window do not show the text.
Please fix that issue, that makes kmail unuseable!
Best regards

Comment 47 Christophe Marin 2017-04-29 16:30:51 UTC

the last backtrace looks unrelated (and misses debug symbols, doesn't manjaro package debug stuff ?)

Comment 48 stefanfrank 2017-05-01 11:42:23 UTC

Hi!
>and misses debug symbols, doesn't manjaro package debug stuff ?

sorry Manjaro base on Arch and unfortunately do not support debug-symbols.
I hope somebody else has the same problem and can upload the debug-log-file.
Best regards
