What makes you think that CSSParser::parseFontFaceSource() is the culprit? Which memory instrumentation tools are you using?</div><div class="">2. Font::platformInit() is the function where we start populating all our internal font caches. For example, we start creating and populating GlyphPages here. It makes sense that it should allocate some memory.</div><div class="">3. Platform fonts are quite heavyweight objects; I would expect these to cost more than the work being done in Font::platformInit(). These are allocated in FontCache::createFontPlatformData().</div><div class=""><br class=""></div><div class="">If you are able; it might be insightful to take a stack snapshot at every memory allocation and aggregate based on the allocation size and the top few frames of the stack. With this information, we can try to figure out what the memory is being used for, and where it should be released. Then we could try to debug why it isn't being released.</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Nov 30, 2015, at 5:10 PM, Vienneau, Christopher <<a href="mailto:cvienneau@ea.com" class="">cvienneau@ea.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="WordSection1" style="page: WordSection1; font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">Hi,<o:p class=""></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class=""><o:p class=""> </o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">I’ve still been tracking memory leaks in our application, and I think I have a good test scenario to share. <o:p class=""></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class=""><o:p class=""> </o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">In our application we found that a lot of memory would be held onto when visiting this particular site:<o:p class=""></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class=""><a href="http://answers.ea.com/" style="color: rgb(149, 79, 114); text-decoration: underline;" class="">http://answers.ea.com</a></span><o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">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.<o:p class=""></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="color: rgb(31, 73, 125);" class="">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.

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<span class="Apple-converted-space"> </span><a href="http://cnn.com/" style="color: rgb(149, 79, 114); text-decoration: underline;" class="">cnn.com</a>, when visiting this page it appears I can expect to lose 100-500k.<o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">Our current code is based off of 188436:<o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">-Are there any known memory leaks that I should pick up a fix for?
