154913 - Crash when canceling a download [@ nsDownloadListener::OnProgressChange ]

Status: VERIFIED FIXED

(Camino Graveyard :: General, defect)

Description

[sairuh (rarely reading bugmail)]

sometimes when i cancel a download, chimera will crash. it doesn't happen all
the time, but below is a test which is reproducible. i'm also on a slower
connection (DSL at home, as opposed to the T1/high speed in the office), which
might make it easier to repro.

found using the 2002.06.27.05 chimera build.

1. bring up the context menu for the URL
http://ftp.mozilla.org/pub/mozilla/nightly/latest/mozilla-macosX-trunk.smi.bin
and select "save link as"
2. the download progress dlg appears --let it download for at least 5-6sec, then
click the Cancel button.

results: crash. report coming up...

looks like a throbber crash. Can you reproduce this without a throbber on the
toolbar?

why was this marked a duplicate of the meta blockers bug? or, did you mean to
make this a blocker for bug 147975? i'm guessing the latter and reopening...

will test this out with a more recent build in a bit...

hrm, well i'm now at the office with a highspeed connection and cannot repro
this using 2002.07.01.05 nb. i can try this again once i'm at home...

saari, i don't *think* i had the throbber icon in the toolbar when i had
encountered this using the 6/27 build. but, i'll doublecheck.

i fixed a bug with this stacktrace on 6/27. if you can't dupe it, that's good
cuz that bug was verified on 6/28 ;) it was bug 154277

07-01 build.

yes, I did mean that this blocks 147975 and not a dupe of it.

I see that the stack is the same as the stack for bug 154277, and that 154277
was verified.  However, following Sarah's original bug report, I'm still able to
repro the bug and crash it (in the office) and get the same stack trace as the
one that Sarah attached in this bug.

Reopening... :(

gah, now that i'm testing this at home...i cannot repro using the 2002.07.01.05
nb. fooey! then again, the throbber icon is not in the toolbar... i'll check
this out a bit more.

fwiw, i've trashed (moved) my profile, to avoid bug 155143.

okay...maybe this should fall under the realm of "tricky to repro"... because
now i can repro this. not this the URL i had originally reported which oddly
wfm, but (at least *this* time) with
http://ftp.mozilla.org/pub/chimera/nightly/2002-07-01-05/Chimera.dmg.gz

a large file is at least needed for this to occur, i think.

also, i got this to crash whether or not the throbber icon was in the toolbar.

->sdagley for investigation. How tricky is this to reproduce

Comment 11

[Mike Pinkerton (not reading bugmail)]

yes, this is still happening. very easy to see in the debugger. mine, i have a fix.

Comment 12

[Mike Pinkerton (not reading bugmail)]

fixed.

Comment 13

[sairuh (rarely reading bugmail)]

unable to repro this using the sample links here (plus some others) using
2002.07.08.13 nb. mind you, this is from my office machine (faster connection)
--is anyone else able to repro this now?

marking vrfy'd fixed --pls reopen if it's still an issue.
