Hi,
I've still been tracking memory leaks in our application, and I think I have a
good test scenario to share.
In our application we found that a lot of memory would be held onto when
visiting this particular site:
http://answers.ea.com
In a loop we visit this site, and a simple html page that consists of a list of
test urls found on the local hard drive.
Our in built memory tools suggest a leak is coming largely from
CSSParser::parseFontFaceSrc(), though admittedly I've changed my top suspects
from time to time. I think this item is showing as a large leak due to the
inclusion of the font in the css on the answers.ea.com page, but perhaps there
are more smaller items being leaked which is just less obvious (the font is
large).
I've reproduce the scenario in the WinCairo test application, based on 188436.
I built in a quick and hacky soak mechanism to conduct the test, perhaps there
are better tools I'm not aware of. I've attached the source changes to this
mail:
Source/WebKit/win/WebKitMessageLoop.cpp
Tools/WinLauncher/Common.cpp
I can see the memory of the WinLauncher process grow over time, here is an
example of the memory usage as seen from the windows task manager over time:
Duration Memory (reported by windows)
0m 155MB
13m 178MB
23m 199MB
36m 219MB
53m 247MB
1h4m 259MB
1h23m 277MB
After about an 1h30m, WinLauncher crashes, at the end of the mail is the basic
debug data that was available.
I'm not sure if the crash is related to the memory leak I'm experiencing, or if
it's an unrelated issue. Since we're a few months older from tip I'm wondering
if anyone has any recent insights to share on this memory leak scenario? I
haven't identified anything in the change logs, but perhaps there is there
something already addressing this? Does the same issue occur at tip?
Any feedback is appreciated,
Thanks

To add some more information to this, the allocation that seems to have the
largest delta amount of allocations between test iterations is:

To me this likely indicates this is what is leaking, does this bring up any

Subject: Memory leak tracking in WebKit
Hi,
I'm currently trying to track a leak in our port of WebKit. If left to soak in
an automated test, looping over 100 websites, visiting each for 10 seconds, for
an evening, I'm finding that memory usage goes up to well over a gigabyte
(eventually crashing). I know that a lot of things could remain cached but I'm
calling code very similar to
MemoryPressureHandler::releaseMemory(Critical::Yes, Synchronous::Yes) before
checking the memory counters built into our application. Manually trying to
reproduce the leak, I find that many pages don't seem to exhibit any
identifiable increase in memory when; starting from a simple page, clearing the
cache, visiting the test page, returning to the simple page and finally
clearing the cache. I have identified some pages which seem to be causing a
problem such as cnn.com, when visiting this page it appears I can expect to
lose 100-500k.
Our current code is based off of 188436:
-Are there any known memory leaks that I should pick up a fix for? (I searched
but nothing seemed relevant to the current code I have).
-Are there any tools or techniques that can be recommended for identifying a
leak? I've been improving our debug features of our memory system, but I've
been unable to solidly identify where the memory is going.
-I have the WinCairo sample built at the same revision, are there any memory
tools that can be used with it to identify if the leak exists there too?
Thanks for any suggestions
