[Bug 233549] New: [database] Stuck at saving jpeg

[Johannes Wienke-3]

https://bugs.kde.org/show_bug.cgi?id=233549

           Summary: [database] Stuck at saving jpeg
           Product: digikam
           Version: unspecified
          Platform: Archlinux Packages
        OS/Version: unspecified
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           trunk (using KDE 4.4.2)
Installed from:    Archlinux Packages

Since the database branch was merged to trunk digikam sometimes gets stuck at
94% while saving an image. The complete gui (album gui and editor) is
completely dead.

This is the debug output:

Maybe it's also worth to notice that this only happened for me when a new image
is generated in the database as a result of the saving process.

I remember a similar problem of yours with a backtrace recently, dont remember
where. Can you attach gdb when digikam is stuck and give a backtrace?

Ok, even if digikam doesn't hang, this error message appears every time.
Moreover the database connection is completely closed then without any user
notification and suddenly there a no more albums and images visible in the
album view.

First of all, the user should be notified that something bad has happened with
the db connection and that this most likely doesn't mean any data loss.

Second, it shouldn't happen at all. ;)

This must be related to copying the tags because it doesn't happen if the
source image has no tags assigned.

SVN commit 1115276 by mwiesweg:

The DatabaseErrorHandler is a great mechanism to give feedback to the user,
mostly in the case of a MySQL connection error.
It now came to be used a bit too often - for every db error that came along,
and in that case, disabling all subsequent db actions.

Move error classification to the backend. Use the error handler for connection
errors only, the code to display a message box is currently unused.
Tolerate the occasional SQL error (which should be debugged, but not impair
user experience).

Hope this fixes the problem. Johannes, can you test with your established
testcase?

Ok, now the database isn't disconnected. Should the SQL warning still be
printed on the console? Because I can't find that message too.

Marcel, I could send you my db file if you want to.

I cannot reproduce them. Or did they move to the new debug output are and are
thus swallowed? Self-healing database ;)

Unfortunately this isn't fixed (anymore). Right now the same situation as
described above happens again every time with these console messages:

digikam(20429)/digikam (core)
Digikam::DatabaseCoreBackendPrivate::debugOutputFailedQuery: Failure executing
query:
 "INSERT INTO ImageTags  (imageid, tagid) SELECT ?, tagid FROM ImageTags WHERE
imageid=?;"
Error messages: "constraint failed Unable to fetch row" 19 1 "constraint
failed" "Unable to fetch row" QSqlError(-1, "", "")
Bound values:  (QVariant(qlonglong, 47941) ,  QVariant(qlonglong, 47854) )

Hm, right now I can't, but what did you change on the database handling since I
reopened the bug?
