Reproducible: Always

Steps to Reproduce:
1.Setup an imap account (gmail in this specific case)
2.Click on the date column to make the newest message top most

Actual Results:  
Tbird becomes unresponsive for a while then crashes

Expected Results:  
Messages should be reordered by date

Comment 2

[Gary Kwong [:gkw] [:nth10sd] (NOT official MoCo now)]

an mxr link is here:

http://mxr.mozilla.org/seamonkey/source/xpcom/glue/nsAutoLock.cpp#467

Please try and reproduce with an official nightly trunk build, with that we'll know if it only applies to debug builds or not, before we confirm.

Comment 3

[Emre Birol]

Nightly works fine. Could be my build settings..

Comment 4

[Emre Birol]

My build environment is proven to be sane. Build settings are fine. Additionally TB 2.0 self built works fine and doesn't crash on reorder. I reopen this bug since there is possibility that this is a real bug.

Trunk built on Darwin 9.2.1, native binary (Intel), crashes consistently. Would be great if somebody try to reproduce it on a similar configuration. I am using my gmail account (IMAP) to reproduce it. For proper testing, test with a new profile. Existent profiles sometimes work fine. Plus, date should be the first column to be reordered. Reordering another column before the date column, makes it work for some reason.

sorry, this doesn't make any sense. the lines seem the same for 1.8.0, 1.8, and trunk.

1   libnspr4.dylib                      0x00554072 PR_SetThreadPrivate + 445
(prtpd.c:215)

afaict implies that you're de-referencing a null pointer verty close to line 215. 215 doesn't exist in release builds, so assuming you're using a release build that's /probably 216/, but you should have returned earlier or crashed earlier.

Comment 6

[Emre Birol]

I am testing with a debug version, and I can say that the problem is not de-referencing a null pointer. The problem is the casting the 'data' object to nsISupports.. 

Please see;
http://mxr.mozilla.org/seamonkey/source/nsprpub/pr/src/threads/prtpd.c#212

above line calls the dtor and the dtor tries to call static_cast<nsISupports*>(data)->Release(); 

data is not null but obviously not a valid memory address neither. I don't think this is a bug in NSPR or in AutoLockBase class. My tentative take on this that this problem looks like a race condition, and related to Bug 370229 in term of thread boundary crossing. Additional note, crash happens sometimes in main thread, sometimes in other threads (in different locations) while main thread doing some DOM stuff - which makes me draw a correlation between this bug and bug 370229. 

One last thing; I can easily reproduce this bug with a TB-Trunk debug built on  Windows XP, with MSVC v8 also. 

Possibilities are;

1- My builts on both platforms are insane, and nothing wrong with TB Trunk -- hmm

2- This bug related to IMAP protocol implementation/threading and happens in very rare conditions.. 

timeless; if you have enough bandwidth, would be great go ahead and try a built on your system. I think this bug is important enough to be a blocker for the release. 

thanks,

Comment 7

[Emre Birol]

To reproduce the bug create a new profile and setup a new IMAP account. If the existent profile is already sorted, it doesn't crash.

Comment 8

> The problem is the casting the 'data' object to nsISupports..

ok, that's a start.

>  above line calls the dtor and the dtor tries to call

can you find who set the dtor? that's very whacky.

 157 static void InitAutoLockStatics()
 159     (void) PR_NewThreadPrivateIndex(&LockStackTPI, 0);

things to do:
1. breakpoint PR_NewThreadPrivateIndex, if you're using windbg
<http://developer.mozilla.org/en/docs/How_to_get_a_stacktrace_with_WinDbg>
you can actually do:

bp nspr4!PR_NewThreadPrivateIndex "kp; g"

that'll give you auto stacks for all such calls (relatively fast).
you could also do things like

bp nspr4!PR_GetThreadPrivate "kp; g"
bp nspr4!PR_SetThreadPrivate "kp; g"

which would get you auto stacks for the other bits.

>  data is not null but obviously not a valid memory address neither. I don't
>  think this is a bug in NSPR or in AutoLockBase class.

you probably will eventually need a data breakpoint. in windbg that's
ba. figuring out exactly how to use it will require effort (and it
will slow things down).

i see three possibilities:
1. someone is stomping on LockStackTPI
2. someone is stomping on the nspr destructor field for LockStackTPI
3. someone is stomping on the value of LockStackTPI per thread (this
is the least likely as it doesn't make any sense)

interesting.

offhand, this sounds like xpconnect is the other involved party (js is
an unlikely third). note that if this is solvable by fixing
thunderbird to not call dom from random threads, then that's the thing
to do.

> 2- This bug related to IMAP protocol implementation/threading and happens in
> very rare conditions..

sure

things to try:
a. the various breakpoints (at the very least, please figure out if
someone is confusing thread private indexes. Each consumer of
PR_NewThreadPrivateIndex should have its own unique index and each
PR_[GS]etPrivateIndex should always use the index reserved for it by
its module (and not someone else's!)

b. some of the other stuff above
c. i have patches for DEBUG builds which cause xpconnect to reject all
access for non threadsafe objects. you'll get some errors and things
will break, but if it causes the crash to go away, then well...

Attachment: Data corruption patch revision 1

http://bonsai.mozilla.org/cvsblame.cgi?file=/mozilla/mailnews/base/src/nsMsgDBView.cpp&rev=1.305&mark=1991,3808,3809,3816#3816

There is a data corruption but not because of race condition nor because of other threading related reason. It's simpler than that. This is my observation;

When TB starts at line 1991, in nsMsgDBView:Open, it reads a value called sortColumns to initialize the m_sortColumns property. For some reason, in a new profile and new account, this value is empty, and as a result m_sortColumns.Length() is 0. That's fine as long as the user doesn't select the 'Date' column to sort as the first thing. Date column (value 18) is default and and it passes the conditions at lines 3808,3809 despite of empty m_sortColumns array. Since it is empty, and op nsTArray<>::[] is not defensive, the statement at line 3818 corrupts memory with an assertion. 

I don't know internals very well nor the logic behind it. So, I propose the attached patch to fix this behavior. 

Would be great if somebody who understands what should "sortColumns" value be, comments on this, and ideally confirms the bug.

Comment on attachment 312161 [details] [diff] [review]
Data corruption patch revision 1

how about m_sortColumns.Length() == 1

:-)

Actually, I much prefer this fix:

    if m_sortColumns.Length())
      m_sortColumns[0].mSortOrder = sortOrder;
    SaveSortInfo(sortType, sortOrder);

Comment 11

[Emre Birol]

Attachment: Data corruption patch revision 2

Submitting the new patch as suggested by david.

David, would be great if you provide some information about the program logic such as;

- Is it acceptable for "sortColumns" option to be empty at the time that nsMsgDBView::Open() is called. Since I don't get this problem with nightly, trying to find out if this is a install issue or not.
- What is the meaning of the magic number 2 (or 1) in line 3808?

Also, is it possible to replace the assertion in nsTArray::[] operator with a WARNING or ERROR or something similar. It is almost certain that if we get this assertion either we corrupt memory by setting a value, or reading an invalid memory address.

thanks for the review.

Comment 12

[timeless]

NS_ASSERTION is correct, failed assertions should be treated as NS_ERRORs
NS_WARNINGs are not critical.

Comment 13

[David :Bienvenu]

It's out of the ordinary for sortColumns to be completely empty, but I know that it happens and I think we should handle it gracefully (I don't remember why it happens).

sortColumns is an array of sort orders - sortColumns[0] is the primary sort order, [1] the secondary order when two headers have the same primary sort key, [2] tertiary, etc, except that I haven't implemented anything beyond the secondary sort in the actual sort - I was hoping someone would step up and do that part, but so far no one has :-(

nsTArray is core xpcom code, so I'm not the person to ask (maybe bsmedberg?) but an ASSERTION seems about right - my guess is that they didn't want any release mode runtime overhead.

Comment 14

[timeless]

perhaps an explanation is in order. nsTArray was written as a way of enabling fast bounds-check free code. it was written with the understanding that only new safe consumers would use it, and that all authors who used it directly would be aware that bounds checking was entirely their responsibility.

yes, it's very much a perf decision.

Comment 16

[Emre Birol]

throwing an exception would be the best thing to do but, exceptions are not used in Mozilla code I guess. 

Break the code at that point in debugging mode would be good since it is guaranteed that this will cause memory corruption.  

Comment 17

[Dan Mosedale (:dmosedale, :dmose)]

(In reply to comment #12)
> NS_ASSERTION is correct, failed assertions should be treated as NS_ERRORs
> NS_WARNINGs are not critical.

Treating failed assertions like an NS_ERROR sounds like something worth thinking about, but it's certainly not how things work now.

(In reply to comment #16)
> throwing an exception would be the best thing to do but, exceptions are not
> used in Mozilla code I guess. 

Right; in the Mozilla code base today, instead of throwing an exception, one returns an NS_ERROR of some sort to indicate that something went wrong.  I suspect that the last paragraph of David's comment 13 is why we don't do that: assertions only take the performance hit when compiled with DEBUG defined.  As he says, though, bsmedberg is more likely to know for sure.

> Break the code at that point in debugging mode would be good since it is

You can do this today with setting the XPCOM_DEBUG_BREAK environment var to "trap".

At some point, we hope to have tinderboxen that turn orange on asserts such that people are required to either fix or back out the patch that caused the assertion.  I think there may already be one or more Firefox tinderboxen that do this (though maybe only on the MozillaTest page?).
