883621 - Error creating Disk Space Watcher

Status: RESOLVED DUPLICATE of bug 895964

(Thunderbird :: General, defect)

Description

[Mitra Ardron]

I'm seeing this error in the Error Console at startup.

While creating services from category 'profile-after-change', could not create service for entry 'Disk Space Watcher Service', contract ID '@mozilla.org/toolkit/disk-space-watcher;1'

Evernote is behaving very poorly, I don't know if this error is related to that problem, but I've been asked enough times to create one bug report per problem. :-(

The real bug I'm trying to track down is Bug #868041 and I'm also seeing Bug #883622 which may or may not be related

I do see it too on Win XP, TB 24 trunk.

The message may come from here:
http://mxr.mozilla.org/comm-central/source/mozilla/xpcom/components/nsCategoryManager.cpp#831

In hg log, there are no recent changes in that file.

FYI. 
Same error is reported for Fx 24. Bug 865348(Win7), Bug 876850(Android)

Comment 4

[Mitra Ardron]

The interesting thing is that the error has stopped appearing for me, AND Bug #868041 has stopped happening, this may suggest that there is some relationship e.g. that the failure that generates this error also does something that a few minutes later stops TB moving files between folders (without generating any error messages despute the failure :-(

What do you make of it?  HOw to reproduce?  Can it cause performance issues?

I still do see it, just by starting TB trunk on Win XP.
From the name of the component, I guess it may just send some events when the disk space is getting low. I have no idea if we use that in any way in TB.

I see this too under linux (32-bit, 64-bit Debian GNU/Linux) when I run |make mozmill| test suite of locally build TB.  Strange, I only began seeing this after this summer (around the beginning of October when I refreshed my local copy of comm-central.)

The error is recorded in the built-in Error Console of TB as follows (as the first item in it):

While creating services from category 'profile-after-change', could
not create service for entry 'Disk Space Watcher Service', contract ID
'@mozilla.org/toolkit/disk-space-watcher;1'


Since the beginning of October, I got the line warning near the start of the |make mozmill| tesst sute.


WARNING: No disk space watcher component available!: file /REF-COMM-CENTRAL/comm-central/mozilla/dom/indexedDB/IndexedDatabaseManager.cpp, line 298


Looking at the surrounding context, I think the call to
create this service is made too early, I think.

You can see that the warning appears immediately after TB binary is invoked before other messages appear.
Also, the recording of the error in Error Console appears as the first item in the recording.

Calling the relevant function to create the service BEFORE the infrastructure (subsystem under a proper thread, etc.) is ready seems to be the culprit IMHO.

[Wayne Mery (:wsmwk)]

Mitra, are you seeing slowness associated with this error

Comment 9

[Mitra Ardron]

I'm not seeing the error any more Wayne. I've updated my machine to one with a lot more disk space, but the error went away previously (in June) as mentioned in Comment #4

Comment 10

[Javi Rueda :javirid]

Still appearing here on OS X 10.9 trunk build just pulled. Also I think error started to show from October, but I haven't been pulling repo very often. Maybe error started showing before October.

I don't build with tests enabled, so I am not able to see any mozmill error, Ishikawa-san.

Well, mozmill suggests that the disk file status is not available when the 
program tries to obtain disk status, presumably remaining empty space, etc.
That sounds bad.

Note |nsIDiskSpaceWatcher| and IndexedDataBaseManager.cpp file name below.
 
Running egrep -i watch lofile-from-mozmill-run, and
removed unrelated lines:

So this could mean some optimization such as prefetch, or database feature is running without being able
to tell if there is enough space available in the disk? Someone in the know can answer this?

Comment 12

[Wayne Mery (:wsmwk)]

the disk watcher error msg is bug 895964 and so likely be ignored and this is a dupe

Comment 13

[Mitra Ardron]

Probably should have done the Dupe the other way around given the comment train here, and that bug #895964 was reported at a later date.
