1355420 - lightning+googleprovider hangs 100% cpu on startup

Status: RESOLVED INCOMPLETE

(Calendar :: Provider: GData, defect)

Description

[L.I.A.R.]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20170321232041

Steps to reproduce:

Upgrade to ThB 45.8


Actual results:

100% CPU + Crash computer


Expected results:

Apparently the problem comes (again) from lightning+GoogleProvider:

My Ubuntu 17.04 recently upgraded ThB to 45.8.0. As soon as I tried to
open the new version it started using 100% CPU, the window was frozen
and the computer crashed. Being used to problems with 1) Master
password with multiple gmail/gcal accounts and 2) the Google Calendar
accesses, I managed to switch off Master Password, regain control of
ThB and then switch off MasLightning+GoogleProvider. Doing so I
managed to get back access to ThB, but only for my emails. Everytime I
tried to reactivate Lightning+GoogleProvider and restart ThB, it went
back to 100%+crash computer.

Since there was a line in the log saying that there was a problem with
an .ics entry (I don't remember the exact error message...), I exited
ThB and deleted the following files:
.thunderbird/xxx.default/calendar-data/cache.sqlite-wal
.thunderbird/xxx.default/calendar-data/cache.sqlite
.thunderbird/xxx.default/calendar-data/cache.sqlite-shm

But this did not work.

I then waited (15 days... without any access to my calendars!!!) for a
notification in ThB 45.8.0 saying that a Lightning and/or
GoogleProvider were updatable. I did the upgrade and managed to get
ThB to run without crashing. Unfortunately, no entry at all appeared
in the calendar tab. Being used to silent authentication problems with
gcals, I opened the preferences and deleted all the gcal OAuth
tokens. When reopening ThB, I was asked for auth again, *but only for
one of the accounts* (even if 2 gcal OAuth token entries were
created). I thus regained access to 1 of the gcals. Since it worked
for one account, I tried to do the process again for the second
account: I deleted again the stored token for the non working gcal and
restarted ThB. I was asked for the password and got an auth token for
this account. Unfortunately, I'm still stuck with no entries appearing
in the calendar tab for this account (the other one works fine). I've
tried to force sync for all calendar, but with no luck.

Having to do all this mess every time a new version of ThB is released
and loosing access to one's emails/calendars for more than 15 days is
realky tedious and really really really not fun in a professionnal
environment...

Also, Thb>Tools>Error Console is so well done that I cannot send you
what I see there as a text!!! So here it is as an image:

Almost everytime ThB gets (automatically) updated on my machine
(currently a Ubuntu 17.04), Lightning+GoogleProvided are a version
behind, thus broken, which makes me loose access to my google
calendars and often ThB also reaches a state where the only solution
is to remove and recreate my whole config (2 google emails + 2 to 5
google calendars).

This is quite annoying...

And I'm not the only one:
https://bugzilla.mozilla.org/show_bug.cgi?id=1169581
http://askubuntu.com/questions/537527/thunderbird-with-lightning-and-google-provider-no-longer-working

Isn't it possible for the Lightning+GoogleProvider devs to follow the
-dev branch of ThB, so that when the -stable branch gets released, a
working version of the Lightning+GoogleProvider plugins gets released
together and everything works fine for the final user? Or at least to
make some automatic transitioning/testing so that when a new version
of ThB is out, the final user is not impacted?

Just found a file in which I had written the error message I saw when running the fresh ThB 45.8.0 from commandline: 
"Error: Error Parsing ICS: 2152333568"
Not sure if it is related to Lightning+GoogleProvider crash ThB&computer...

Perhaps having your assistance in the QA process would be helpful. More volunteers is a good thing.

Comment 3

[Wayne Mery (:wsmwk)]

is this a repeat of bug 1353392, where you have not replied?

Arg.... Sorry... Without my calendar waste a lot of time in my work, sp I went totally lost and I didn't remember having already filed a bug!
However, there are more info in this one than the other one. How could I merge the 2?

I'd suggest the following steps:

1) unsubscribe from all calendars
2) re-subscribe to calendars, one by one
3) when it hangs, wait for a long time (10-15 Minutes?) and let it hang
4) sync should be done after that

The first sync is full, that can hang (unfortunately). Afterwards syncs are incremental, which is fast.

Hi,

Unfortunately, unsubscribing+re-subscribing to my ~15 calendars is not a viable solution. I've already tried that in the past (it is unfortunately not the first time - far from - I encounter problems with ThB+Lng+GP) and this takes waaaaaaaay too much time for mostly random results.

I had found a temporary solution with:
sudo apt-get install --reinstall thunderbird xul-ext-gdata-provider xul-ext-lightning
i.e. by reinstalling versions of ThB and addons that are supposed to work together.

Unfortunately, hangs/crashes are now occurring even with these supposed-to-work versions.

I've triedcreating a new profile with only my emails, but now I encounter the exact same bug as described here:

Just to update the bug - under Linux Mint 64 bit, Thunderbird 52.2.1 (64-bit), Lightning 5.4; there is no Google Provider that will let me see my google calendars "compatible" in any repository that I can find.  the bug is essentially a system hang, with repeated popup error windows claiming a script is not completing, often with the lead of "chrome://" I have had to remove the provider just to use my emails. Works fine on the windows side.

Updating - just checked the windows side, and guess what - it fails there also now.  I get this popup:

Script:chrome://calendar/content/calendar-view-core.xml:123

And I have to C-A-D to stop TB, since it hangs the entire system (windows 7 64 bit, TB 52.3.0 - 32 bit, Lightning 5.4.3, Provider 3.3).

2nd update :  I have a second 32 bit windows 7 system, and the problem does not seem to occur on it; at least not yet.  So the problem may only be with 64 bit systems.

Unfortunately I don't think this bug is actionable at the moment. There are some perf issues in Lightning that are being worked on, the Provider is just using those APIs. I'll be testing with many events though, so this bug won't be forgotten.
