I've attached the stderr log.
Very strange, nothing about sycoca in there apart from the assert.
I am going to need your help on this one.
0) do you have a file called ~/.cache/ksycoca5 ?
No -- before starting krita to test whether it works, I remove the
cache, config and local directories, so I can be sure I'm testing from a
clean setup. After running krita, all three folders are created, but no
ksycoca5 file.
1) please apply this patch to kio/tests/previewtest.cpp and run ./previewtest,
does it work?
http://www.davidfaure.fr/2015/previewtest.diff
Same assert.
2) if it fails just like krita, please put a breakpoint in
KSycocaPrivate::checkDatabase
(which is being called with parameter IfNotFoundRecreate from
KSycoca::findFactory,
just before the assert) and check what happens in there. Also break on
KSycocaPrivate::closeDatabase
to check if it's called (other than the very first time before opening).
What happens is this:
checkDatabase() is called with IfNotFoundRecreate
closeDatabase() is called
kdedRunning is set to false
if (!bus->isServiceRegistered(KDED_SERVICE_NAME)) { evaluates to false
if (QStandardPaths::isTestModeEnabled()) { evaluates to false
kdeRunning is still false
closeDatabase is called()
if (!openDatabase(ifNotFound & IfNotFoundOpenDummy)) { evaluates to true
kded is running, though:
ud@linux:~/kde/src/2.9> ps ax | grep kded
1452 ? Sl 0:05 kdeinit4: kded4 [kdeinit]
1514 ? Sl 0:02 /usr/bin/kded5
Oh wait, could it be that you're hitting the bug that I fixed in kservice.git
bf3f25f27406984a4,
after KF 5.13? Please try cherry-picking that commit.
That doesn't seem to help either... But I'm not sure how much of your
time I should take with this problem -- I might be better off porting
away from kio since I cannot ship something that needs a running daemon
or background process :-(
