Comment 3

[Akkana Peck]

Changing platform to all.  On Linux, I get a crash on exit absolutely every time
with today's or yesterday's commercial release build.  I've filed lots of
talkback reports.

Comment 4

[Akkana Peck]

Here are some talkback reports:

A debug mozilla build says:

XXX WARNING: Number of webshells being leaked: 1 

but does not crash on exit.

Comment 5

[Asa Dotzler [:asa]]

over to layout for further triage.

Comment 6

[Blake Ross]

What really scares me is the report with "UptimeMinutes: 1"

upping severity, nominating for beta2

Comment 7

[Nisheeth Ranjan]

This is a more general bug report of the crash that is reported in bug 41339 
which is marked nsbeta2+.

Marking this bug nsbeta2+ and marking 41339 as a dup of this bug...

Comment 8

[Nisheeth Ranjan]

*** Bug 41339 has been marked as a duplicate of this bug. ***

Comment 9

[Nisheeth Ranjan]

Re-assigning to myself for a more detailed triage...  CCing karnaze and 
waterson, the layout guys for input.

Comment 10

[Nisheeth Ranjan]

I cannot reproduce this in today's morning NT commercial debug build.  Is 
someone else seeing this?  Marking qawanted and updating status whiteboard.

Comment 11

[Akkana Peck]

I still see this every single time I exit with the 6/30 release build.  You're
welcome to try it on my machine (I've submitted several fullcircle reports
already).  Removing qawanted if my assumption is right that it means "need help
reproducing".

Comment 12

[Nisheeth Ranjan]

Updating OS to Linux.  Akkana, does your debug build crash on exit, too?

Comment 13

[Nisheeth Ranjan]

Updating status whiteboard...

Comment 14

[Akkana Peck]

No, my debug build doesn't; just the release, commercial, fullcircle build. 

Comment 15

[Nisheeth Ranjan]

Akkana has fired off an optimized build with debug symbols for me.  I'll use
that to investigate this more on Wednesday....

Comment 16

[Akkana Peck]

I have a debug commercial build available -- but it doesn't crash on exit.  Only
the release build (with fullcircle) seems to have a problem, and today's
fullcircle build still calls up a fullcircle build on exit.  Could this be a
fullcircle-introduced instability?  (I haven't tried making an optimized
commercial build, though; I could do that, if you think it's worthwhile.)

My debug build, if you want it for anything, is on guitar at /builds/commercial.

Comment 17

[Shiva Thirumazhusai]

Are you able to submit the crash report ? 

Comment 18

[Akkana Peck]

Yes.  I've submitted at least ten so far (one from today's build).

Comment 19

[Akkana Peck]

One thing I should have mentioned is that although I don't crash with my
commercial debug build, I do get a couple of asserts when exiting:

###!!! ASSERTION: NS_ENSURE_TRUE(aPropertyName) failed: 'aPropertyName', file
nsFrameManager.cpp, line 1776
###!!! Break: at file nsFrameManager.cpp, line 1776
###!!! ASSERTION: NS_ENSURE_TRUE(aPropertyName) failed: 'aPropertyName', file
nsFrameManager.cpp, line 1776
###!!! Break: at file nsFrameManager.cpp, line 1776

Strangely, I don't get them when running under the debugger.

Comment 20

[Nisheeth Ranjan]

Actually, Akkana, it would be helpful to have an optimized build with debug 
symbols.  Could you fire that off for me?  Thanks a lot.

Comment 21

[Shiva Thirumazhusai]

Since this crash happens in Linus as well as Mac I am changing the OS to all.
Commonly reproducible in the following :-
        OS: MacOS version 8.6
        OS: MacOS version 9.0.4
        OS: Linux 2.2.14-5.0smp

Comment 22

[John Bandhauer]

*** Bug 39858 has been marked as a duplicate of this bug. ***

Comment 23

[Viswanath Ramachandran]

nisheeth, could you put an ETA in this bug so that we can mark the ETA in the 
dependent AIM bug as well. thanks, Vishy

Comment 24

[Nisheeth Ranjan]

I'm doing an optimized build with debug symbols to debug this today and will add 
an ETA as soon as I have a handle on the problem.

Comment 25

[Nisheeth Ranjan]

Eric Pollmann and I couldn't reproduce this with today's commercial build on our 
linux boxes which are running linux 2.2.12-20.  Mike Pinkerton is running Mac OS 
9.0.4 and he couldn't reproduce the crash on exit with today's commercial 
build either.  I went up to Akkana's machine which is running linux 
2.2.14-5.0smp and the crash is reproducable there.

Given that this crash is not reproducable on all machines, we should probably 
not consider this a beta 2 stopper.  I'm removing the beta2+ designation and 
adding a nsbeta3 keyword.

Chris (Petersen), it would be great if we could get some QA on this bug and see 
whether we get a crash on exit on commercial builds with fullcircle enabled on 
different Linux and Mac kernels.

Comment 26

[leger]

Per recent data.  Putting on [nsbeta2-]

Comment 27

[Alek Jeziorek]

I smoketested today's build (2000-07-13-08-M17 commercial) and i got a crash on 
file|quit on Linux and Mac and not on Win32.

Comment 28

[Akkana Peck]

Can we get this reevaluated?  I know it's hard to track down and all that, but
it's not just my machine, and we're going to look really bad if we release a
beta where the user can't exit without getting a fullcircle dialog every time.  

We have *lots* of fullcircle reports on this crash.  If fullcircle reports
aren't useful for helping to track down crashes, why are we inflicting them on
users?

Comment 29

[Nisheeth Ranjan]

I agree with akkana.  I think this bug should be nsbeta2+ given that other 
people are seeing this crash too...

Comment 30

[Jay Patel [:jay]]

Putting on [nsbeta2+] radar for beta2 fix. 

Comment 31

[chris hofmann]

sound like we just need to make a debug build,
drop the fullcircle binaries and master.ini
into the debug build tree and run the exit test
case to figure see if the full circle binaries
are creating the instability.

Comment 32

[Shiva Thirumazhusai]

Steps tried to reproduce :-

Created a Mozilla Debug Build
Created Netscape Commerical Debug Build with fullcircle enabled
Copied master.ini
Launched Netscape6 and ran with few pages and exited.
No crash. 

Next Step:-
Build Mozilla Optimized Build with Symbols.
Build Netscape Commercial Optimized Build with Symbols and fullcircle enabled.
and Same steps as above case.

Hope I can reproduce. Anybody have other ideas ?

Comment 33

[Akkana Peck]

I'll be glad to try running anyone's build on my machine, if you want to make it
available -- just let me know where to NFS mount or ftp the build.

Comment 34

[Nisheeth Ranjan]

So, I built an optimized build with debug symbols on Linux.  I ran the build and
exited and did not see a crash.  I've added my build directory to /etc/exports,
Akkana, so you can nfs mount /builds on anubis and get to the build.  The full
path is /builds/nisheeth/ns/dist/bin.  Please update the bug report with what
you find when you run this build from your machine.  If you see the crash on
exit, we can debug this together tomorrow.  Thanks!

Comment 35

[Nisheeth Ranjan]

Updating status white board - the ETA is indeterminate until this problem is
reproducable in a debuggable build.

Comment 36

[Alek Jeziorek]

Still seen on commercial Linux with build 2000-07-19-08-M17, but i do not see a 
crash using commercial Mac anymore

Comment 37

[Akkana Peck]

Unfortunately, I don't seem to see it on the anubis build.  I'll try a few more
times, but it's not looking good.

Comment 38

[Nisheeth Ranjan]

Alek, I've made a tarball (ns.tar.gz) of a fullcircle enabled optimized build 
with debug symbols available in my home directory (/u/nisheeth).  Please install 
it on the box where you were able to reproduce the crash and run it.  If you can 
reproduce the crash with this build, we can try and debug this tomorrow evening.  
I will be away during the day for a class.

Comment 39

[Nisheeth Ranjan]

Turns out Alek wasn't on the cc list.  Adding him.  Alek, please see my comment 
on this bug right before this one.  Thanks!

news steps to reproduce the crash on linux:
-start browser
-File|Open File
-let it open a file in a new browser
-then in either browser window File|Quit *NOTE*: its crashes on only File|Quit
-100% reproducible

Comment 42

[Nisheeth Ranjan]

Attaching a patch that fixes this crash.  Can somebody on the cc list please
code review this?  Thanks.

no longer seen on any platforms with commercial builds 2000-07-24-08-M17 

Comment 47

[Akkana Peck]

Really?  I'm still seeing the crash with the 7/24 sweetlou commercial build.

I'll try downloading one later today.  Maybe I got mislabelled bits or something
(wouldn't be the first time that had happened).

Comment 48

[Alek Jeziorek]

i've ran through the whole browser test File|Quiting after every test case and 
can't reproduce a crash using build 2000-07-24-08-M17 
Akkana: maybe the crash is specific to your computer.

Comment 49

[Shiva Thirumazhusai]

Is this problem due to smp ?

Comment 50

[Akkana Peck]

Not SMP: I only have a single processor.

Using today's build as dogfood, I'm seeing a LOT of crashes doing practically
everything.  In addition to the crash on exit, which still happens, I've been
getting random crashes in practically every area of the product, perhaps every
20-30 minutes.

I've switched to the mozilla build (no fullcircle); so far I've seen one crash,
which isn't enough to tell for sure whether it's more stable or not.

Comment 51

[Shiva Thirumazhusai]

Akkana, your machine is Single processor machine. My suspicion is the kernel
is smp.(I may be wrong). The following information I got from Talkback incident.
This could be the reason.

 System Information: 
 Linux
 2.2.14-5.0smp
 #1 SMP Tue Mar 7 21:01:40 EST 2000

Comment 52

[Akkana Peck]

This is the standard kernel that Redhat 6.2 installs.  I did a vanilla Redhat
6.2 install and haven't changed the kernel.

Comment 53

[Akkana Peck]

Note, I'm still seeing this in the 7/28 build, though it's a little more
difficult to reproduce.

Here's how I make it happen:

1. Make sure I have a chrome directory under my profile directory.  It doesn't
happen if I move my chrome directory aside.  (Users will have a chrome directory
if they've mucked with themes, or if they've installed a user.css.  It's not my
user.css causing the problem -- moving it aside doesn't make the crash go away,
only moving the whole chrome directory, and there's nothing else of note in the
chrome directory.)
2. Run mozilla http://www.mozilla.org
3. Click on the mail icon in the taskbar to bring up a mail window.
4. When Inbox has loaded (mine is IMAP, probably doesn't matter), click on a
message to read it.
5. Click on another message to read that one.  (I have to read a second message
or I don't see the crash.)
6. Alt-Q to exit.
A fullcircle dialog will come up.

I'm going to reopen since the crash is still completely reproducible for me.

Note: may possibly be related to bug 46849, which I just filed.

Comment 54

[Blake Ross]

Are the new steps still worthy of nsbeta2+?  Or can we relnote it?

Comment 55

[Akkana Peck]

Probably okay to relnote it, hoping people won't play with skins much, or
anything else that might make a chrome directory.

Comment 56

[leger]

Does it crash on exit is you use Close Box instead of File/Quit?

Comment 57

[Akkana Peck]

No, doesn't happen if you close the windows one at a time instead of exiting the
app.

Comment 58

[Jay Patel [:jay]]

Putting on [nsbeta2-] radar.  Not critical to beta2.  Adding "relnote" keyword 
for PR2 release.

Putting on dogfood+...can we get this fixed ASAP?

Comment 61

[leger]

this is on Linux only.  Updating OS info.

Comment 62

[Nisheeth Ranjan]

Marking nsbeta3+

Comment 63

[selmer (gone)]

Please add an ETA for the dogfood+ bugs.  Thanks, PDT

Comment 64

[Nisheeth Ranjan]

Adding ETA...  I don't think that this should be a dogfood bug because a crash 
on exit does not hamper the usability of the product.  Removing the dogfood+ 
marker and keeping it on the beta 3 radar.

Comment 65

[Akkana Peck]

It only hampers usability of the product if there are prefs/rdf/other info which
only get saved on exit.  I'm not sure whether that's currently the case.  A lot
of our prefs seem to get written out as soon as they are changed, and if so,
this bug becomes much more minor (in fact, if we turned off fullcircle, users
wouldn't even know there was a problem).

Comment 66

[Shiva Thirumazhusai]

Does it core dump when fullcircle is removed ?

Comment 67

[Akkana Peck]

Yes, but since current versions of Linux don't save core files for multithreaded
apps, the user doesn't know it has core dumped; it just looks like a normal
exit.  The only clue/annoyance the user has that anything is wrong is the
fullcircle dialog coming up.

Comment 68

[Nisheeth Ranjan]

Marking P1...

Comment 69

[Phil Peterson]

PDT agrees P1 with some dissension :-)

Putting [pdtp1] in whiteboard

Comment 71

[Nisheeth Ranjan]

I changed themes from the preferences menu and then went through the 6 steps
listed in Akkana's post timestamped 7/28/2000 14:02 on an optimized, full circle
enabled Linux build with debug symbols.  I could not reproduce the crash on
exit.

Akkana, my build is located on "g" in /export/nisheeth/ns/dist/bin.  Could you
run it from your user account and see if you can reproduce the crash?

Also, Akkana mentioned in her post cited above that the crash could be related
to bug 46489.  That bug has been fixed since then, so, maybe this crash on exit
has been fixed as a result.

Comment 72

[Akkana Peck]

I don't see a fullcircle dialog when I go through the steps with this build.

I do see an assertion at shutdown:

###!!! ASSERTION: Component Manager being held past XPCOM shutdown.: 'cnt == 0',
file nsXPComInit.cpp, line 667
###!!! Break: at file nsXPComInit.cpp, line 667

but there doesn't seem to be a crash associated with it.

Comment 73

[Nisheeth Ranjan]

Akkana just tested a commercial build on her box and that does not crash any
more either.  Marking bug worksforme.

Comment 74

[Joseph Elwell]

verifying. using linux 2000-09-26-09-MN6 mozilla build, Mozilla doesn't crash on
exit.

Comment 75

[Shiva Thirumazhusai]

Moving all the Works For Me bugs to talkback user account for future reference.

Comment 76

[Shiva Thirumazhusai]

We are gathering all the Resolved and WFM bugs which are happened to be topcrash 
bugs and assigning it to talkback. I am marking all of them as RESOLVED WFM.
