I get the following error during local mochitest testing of debug version of TB under linux.

WARNING: Scrolled rect smaller than scrollport?: file /NEW-SSD/NREF-COMM-CENTRAL/mozilla/layout/generic/nsGfxScrollFrame.cpp:7064

The line number is a bit off from the pristine tree due to my local patch to dump the rectangle size.

These are visible in other people's tryserver run of debug version.

See, for example, geoff's job on
Fri, Feb 26, 10:36:47
https://treeherder.mozilla.org/jobs?repo=try-comm-central&selectedTaskRun=UHH5kKDXQZajtn4GSyAkOQ.0&revision=f8aba0f45fa5b6f168f08143c272f630871ad4f8

You can find the warning in, say,
https://firefoxci.taskcluster-artifacts.net/UHH5kKDXQZajtn4GSyAkOQ/0/public/logs/live_backing.log

So this is not a local problem.

I am attaching the list of either the height or the width of the rectangle when the warning is printed.
That is produced by

egrep "result.(height|width)" log1297-mochitest.txt

Please note that there are two places where the warning is printed.

Shorter height:

Shorter width:

There are more warnings for shorter height than for shorter width. The number at the beginning of the warning is the # of appearances in the log.

The following is the list of NS_WARNING messages from the mochitest
log in the descending order of appearances. (JavaScript warnings are
not counted here.)

The relevant warnings are marked with "*" at the beginning the line.

 ... warnings that don't appear more than 100 times are omitted.

From the attachment, you can see there ARE cases when the resulting width is 0.
This certainly sounds strange and can be the cause of various strange display errors.

Bug 562510 is for MacOS, and it looks to be FF-specific and very old.
I doubt it is related.

So I filed this separately.

This is the patch I used to dump the relevant values.

I think this could be dup.

https://bugzilla.mozilla.org/show_bug.cgi?id=810274
Bug 810274 seems to have inserted this check and explains the background in detail regarding sub-pixel scroll.
Now that we have a new drawing engine, maybe the situation could improve.

Anyway, more than 3K warnings during a test run seems a bit excessive, and one wonders naturally what goes on.

Summary: WARNING: Scrolled rect smaller than scrollport during debug version TB mochitest → WARNING: Scrolled rect smaller than scrollport during debug version Thunderbird mochitest

We still get more than a few thousand warnings in mochitest locally done under Debian GNU/Linux.

Warning that does not appear more than 100 times is omitted.

This warning is very common in Firefox as well.

(In reply to Timothy Nikkel (:tnikkel) from comment #5)

This warning is very common in Firefox as well.

Thank you for the clarification.
Then I take it that this is not a serious situation, but known rare cases where the normal larger-than relation no longer holds.

If so, I wonder if we can create a macro which prints "INFO:" instead of "WARNING:" for these
not-so-serious, but the-developer-will-be-better-informed-about-the-real-world-situation-if-we-print-the-instance-of-rare-case-processing messages.
I would be more comfortable with INFO: as in

...  Main Thread] INFO: Scrolled rect smaller than scrollport?: file /NEW-SSD/NREF-COMM-CENTRAL/mozilla/layout/generic/nsGfxScrollFrame.cpp:7154

I probably can ignore the message thinking that this serves its purpose to those who develop the code in question and not of general concern to those who is producing patches and is trying to make sure his/her patches do not break FF/TB. (Come to think of it,
if patches break FF/TB, the rare situations may happen more often and so we need to pay attention to them anyway. Hmm.)

In any case, we may want to reduce the number of "WARNING:" messages somehow to make the debug test log more useful IMHO.
If it means we swap some of "WARNING:" messages to "INFO:" messages, I will be fine.

Just my 2 cents worth.

Yeah, I don't think it's that important, if it was more serious I would expect it to be an NS_ASSERTION or fatal MOZ_ASSERT.

I agree that the amount of debug spam (including this warning) is too much and we should try to reduce it.

Hear, hear. :-)

This can happen on regular content (I see it when loading google.com on
a debug build for example). Given there's no action to take it seems
only noise atm. No strong opinion into whether it's better to ifdef the
code or just remove it.
