Hello,

I launch the same process now to see if I can reproduce it.

Eric

I recently fixed a huge memory leak in thumbnail process from maintenance tool. Look this entry for details :

https://bugs.kde.org/show_bug.cgi?id=326525

Gilles Caulier

Hello,

I have read that post.

I use : Date de compilation : Oct 31 2013 (cible : debugfull)
Rév. : ea2847ec161df82f8d64e70afdbc5d12feb7708e

I update my git repositories on git digikamsoftwarecompilation yesterday.

So your modification have been apply (ensure by a diff on files that have been modified).

I use a local start, with a script from terminal. Since this last update, I can't quit digikam too, no crash, but I have to do ctrl+c after clicking on quit in menu. It's hang on a "infinite time" without closing digikam.

terminal output :
digikam(30861)/digikam (core) Digikam::ImageScanner::commit: Scanning took 61 ms
digikam(30861)/digikam (core) Digikam::ImageScanner::~ImageScanner: Finishing took 538 ms
digikam(30861)/digikam (core) Digikam::CollectionScanner::completeHistoryScanning: items to tag (22180)
digikam(30861)/digikam (core) Digikam::ImageScanner::tagImageHistoryGraph: Graph with 2 vertices:
"{ Id: 22180 UUID: 3b6a2a... } -> { Id: 61131 UUID: ac2c01... }"
digikam(30861)/digikam (core) Digikam::ImageScanner::tagImageHistoryGraph: Image 22180 type QFlags(0x1|0x8)
digikam(30861)/digikam (core) Digikam::ImageScanner::tagImageHistoryGraph: Image 61131 type QFlags(0x8)

Digikam never close, and no more logs or shutdown message (quit in menu, ctrl+q) .

I try to reproduce it : I'm not sure it's related to thumbnail maintenance : maybe something with threads and closing opening windows.

Thank you,

Eric

And for memory, it's good. Digikam don't full fill memory anymore when rebuilding thumbnails.

? perhaps something to do with the progressmanager modification ?

yes, the crash is due to my last changes in progress manager, from this entry :

https://bugs.kde.org/show_bug.cgi?id=302810#c5

Before this fix, digiKAm crash because main application is closed when progress tasks still running.

My patch must wait than all progress tasks are stopped before to close main application.

Here it doesn't crash when thumbnails are processed in progress manager and when i close digiKam by window manager close button.

Which condition you use exactly to reproduce the crash as :

- how many progress task are running ?
- Which progress tasks are running ?
- which digiKam windows are open when you close application (as light table, albumui, import tool, BQM) ?
- You press CTRL+Q to quit application ?
- It crash when you close application through window manager close button ?

Gilles Caulier

Hello,

I - For the  "Digikam doesn't properly close - never close" :  nothing is done, simply start digikam wait all digikam starting task are to end then ctrl+q (or other stuff to close) .

In this exemple :

digikam(30861)/digikam (core) Digikam::ImageScanner::commit: Scanning took 61 ms digikam(30861)/digikam (core) Digikam::ImageScanner::~ImageScanner: Finishing took 538 ms digikam(30861)/digikam (core) Digikam::CollectionScanner::completeHistoryScanning: items to tag (22180) digikam(30861)/digikam (core) Digikam::ImageScanner::tagImageHistoryGraph: Graph with 2 vertices: "{ Id: 22180 UUID: 3b6a2a... } -> { Id: 61131 UUID: ac2c01... }" digikam(30861)/digikam (core) Digikam::ImageScanner::tagImageHistoryGraph: Image 22180 type QFlags(0x1|0x8) digikam(30861)/digikam (core) Digikam::ImageScanner::tagImageHistoryGraph: Image 61131 type QFlags(0x8)

I only wait digikam finish starting and then ctrl+q.

- how many progress task are running ?
none

 - Which progress tasks are running ? 
none
- which digiKam windows are open when you close application (as light table, albumui, import tool, BQM) ? 
only main windows
- You press CTRL+Q to quit application ? 
yes, and try other like clic on quit in menu 
- It crash when you close application through window manager close button ?
No, for this "Digikam doesn't properly close - never close", not crash.

II - I was thinking it should be in link with :
Digikam crash while scanning pictures for thumbnails maintenance which produce this:

digikam(29444)/KEXIV2 KExiv2Iface::KExiv2::Private::printExiv2MessageHandler: Exiv2 ( 2 ) : Directory Minolta, entry 0x0088: Data area exceeds data buffer, ignoring it. digikam(29444)/digikam (core) Digikam::DImg::load: "/media/DiskphotosTests/maison annoeullin/PICT0538.JPG" : JPEG file identified digikam(29444)/KEXIV2 KExiv2Iface::KExiv2::getImageOrientation: Orientation => Exif.Image.Orientation => 1
 [xcb] Unknown request in queue while dequeuing

[xcb] Aborting, sorry about that. digikam: ../../src/xcb_io.c :179 : dequeue_pending_request: l'assertion « !xcb_xlib_unknown_req_in_deq » a échoué.

- how many progress task are running ?
only one, scanning thumbnail with maintenance tool (no analyse)
 - Which progress tasks are running ? 
only one : scanning thumbnail
- which digiKam windows are open when you close application (as light table, albumui, import tool, BQM) ?
only main window
 - You press CTRL+Q to quit application ? 
no, I play with reduce and resize with digikam main windows : 
- It crash when you close application through window manager close button ?
no, when play with windows. When I'm trying to close digikam, it never end and no crash.

I have two problems which are in relation I think.

Thank you,

Eric

None of both case are reproducible on my computer.

I suspect that problem is in another place that first expected...

Just to be sure :

- Do you compile digiKam with this cmake option : "-DDIGIKAMSC_USE_PRIVATE_KDEGRAPHICS=on". This force digiKam to use libkipi, libkdcraw, libkexiv2 from digiKam SC source code instead shared libs in your system. HEre it's compiled like this. This includes all last code from git/master
- Can you clean up whole digiKam compilation and make a new cmake config (use bootstrap.linux script) and recompile all. You can remore "build" sub-dir to clean-up. After that try again to reproduce the problem...

Gilles Caulier

Gilles,

I'm trying now to reproduce the II.
1 - launch digikam
2 - launch in main window a maintenance thumbnail scan with no analyse
3 - wait it run for a while, then play with digikam window (reduce ... but not close)

and try to give you a backtrace for :
[xcb] Unknown request in queue while dequeuing 
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called 
[xcb] Aborting, sorry about that. digikam: ../../src/xcb_io.c :179 : dequeue_pending_request: l'assertion « !xcb_xlib_unknown_req_in_deq » a échoué.

Thank you

- Do you compile digiKam with this cmake option :"-DDIGIKAMSC_USE_PRIVATE_KDEGRAPHICS=on" ?
Yes and it does

HEre it's compiled like this. This includes all last code from git/master - Can you clean up whole digiKam compilation and make a new cmake config (use bootstrap.linux script) and recompile all. You can remore "build" sub-dir to clean-up. After that try again to reproduce the problem...

I use to cmake config with bootstrap.local (to have a working digikam 3.5.0 stable and beta version for test).

As I'm trying to use eclipse, I've made my "own" cmake script :

I can reproduce the problem here, to reduce and restore main window during a progress task.

Gilles Caulier

Marcel,

I can reproduce this crash here when digikam main window is reduced and restored quickly while a progress task (thumbnails generator for ex) is processed.

The trace said :

[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
digikam: xcb_io.c :274 : poll_for_event:  l'assertion « !xcb_xlib_threads_sequence_lost » a échoué.
KCrash: Application 'digikam' crashing...
X Error: BadImplementation (server does not implement operation) 17
  Major opcode: 20 (X_GetProperty)
  Resource id:  0x0
digikam: Fatal IO error: client killed

After investigations, i identified that my patch below is the problem :

https://bugs.kde.org/show_bug.cgi?id=302810#c5

... especially, the QEventLoop that i plugin in ProgressManager class here :

https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/entry/libs/progressmanager/progressmanager.cpp#L384

I use it to wait progressitems cancellation when digiKam is closed (see bug #302810)

Why i cannot use QEventLoop here ?
Or i use it in the wrong way ? 

I suspect that ProgressManager run in a separated thread, and X11 don't like it... But it's not the case... right ?

Gilles

e.longuemare,

I found something interesting. I see in your last backtrace some line about color management.
Here, it's the same.

If i disable CM, crash is not reproducible. Can you confirm ?

Hello,

I launch the test now and see if it's the same :
1 - disable color management in digikam conf
2 - then launch a task (thumbnails maintenance)
3 - and reduce and restore windows

Thank you.

Eric

To disable CM, just go to digiKam CM setup panel and turn off lead CM option. No need to touch digikamrc file. digiKam setup will do it for you...

Gilles Caulier

Marcel,

My first investigations about QEventLoop has been a wrong way.

It sound like problem is about CM enabled on computer. This setting is used in ThumbnailLoadThread. As instance is created in a separated thread and not main application thread, through a ThreadWeaver::Job, it try to access on X11 API which crash due to non re-entrance...

I see in ThumbnailLoadThread::Private::createLoadingDescription() that so bracket play with CM. I forced displayingWidget to null in ThumbnailLoadThread properties, but i think it's not enough to disable CM in ThumbnailLoadThread.

Perhaps it's the wrong way, and i must to move ThumbnailLoadThread instance outside ThreadWeaver::Job ?

Gilles Caulier

Gilles,

For the moment I try but can't reproduce with cm enable or disable.

What have been changed since yesterday :

I have removed my second display monitor (it will be back in a few hour).
I look at digikamrc and the file was corrupted (but can't reproduce even with this corrupted RC file).

What have not changed :
Digikam can't be quit without ctrl+ c
I have not updated and rebuild digikam (same version which produced the crash yesterday)

So, is it something with Color Management and dual screen ?
Or is it something with some files that aren't process at the moment ?

So I relaunch a thumbnail scan (all collection, all tag) and wait, then try to reproduce.

diff between old digikamrc and new one

I made a mistake in thumbnail database name (digikam main database was the good one). Use the production thumbnail database for the test this morning : digikam_thumbnail (test one is digikam_thumbnail_clone). There are over differences.

Do you have a dual screen. For me, it's my case.

I calibrated one screen and as both are the same, i set color profile file in digiKam CM settings (there is no way that i know under linux to assign a profile for each monitor)

Gilles Caulier

Yes Gilles.
I have lend it to a friend. It will be back this afternoon.
I will try to reproduce.

Yes I use dual screen. But not this morning.

And you want mean that using only one screen and to enable CM, stressing digiKam to reduce/expand main window during thumbnails task do not crash it ?

Gilles Caulier

Yes

Gilles,

I reconnect my second display monitor.
Launch digikam.
Launch thumbnail scan

then clicking on reduce and restore

With two monitor, CM check, digikam crash on reduce restore, and crash or don't quit while a task is in progress

--> crash when quit and a task is in progress
--> doesn't crash but doesn't quit when no task is in progress

Color profile was default digikam one, default CM config, no change except check or uncheck CM.

There is indeed a problem of having a static variable of a displaying widget in ThumbnailLoadThread. At the time of writing, I assume I was not aware of the implications.
A workaround for now could be storing an IccProfile for now in the static_d, instead of storing the QWidget, which is retrieved in setDisplayingWidget.

Git commit 5e19edff8afc8eeca9f3b9cbc92d3a54f23ae533 by Marcel Wiesweg.
Committed on 03/11/2013 at 18:16.
Pushed by mwiesweg into branch 'master'.

Do not store a QWidget in a static variable to retrieve the IccProfile for thumbnails.
This crashes in case the thread is used from a non-UI thread.
Instead, store the IccProfile when the widget is set. This is not perfect, the
previous solution was not perfect either.
Note: For thumbnails, the profile setting is global for performance reasons

Eric,

After last Marcel commit from comment #40, are you able to reproduce the crash ?

Gilles Caulier

Eric,

I checked last commit from Marcel, and crash is not reproducible here...

Gilles Caulier

Thank you Gilles,

I will update, compile and test today.

How I'm building :
1 - do a ./download-repos in my sources folder :  dkgitdigikamsoftwarecompilation
2 - as nothing update (for digikam since 
3 - do a git pull in master branch of my sources in another folder : dkgitdigikammaster, that containt developpment repositorie
4 - do a diff of content of folder dkgitdigikammaster and dkgitdigikasoftwarecompilation/core/
5 - cp changed or added files from dkgidigikammaster to dkgitsofwarecompilation/core/
6 - do a make, then a make install in my builddigikamsofwarecompilation folder

    There's a simple problem with slotAbortAll: The event loop is entered and never quits
    if there is no active ProgressItem.
    Add a check which returns from the method if the list of ProgressItems is empty.
    Gilles: Please check if this is ok.
