Thanks Marco for raising the bug. here are some other leaks i observe on the linux/gtk/arm platform (>50k per caller), this is with a run of opening around 30 random pages. The heap size goes to 45M, so definitely there are big leaks in the gtk port.
i will try to find the caller to the next level and split up the generic functions. meanwhile, let me know if there are fixes available for any of these thanks, Zaheer <caller>: WTF::Vector<char, 0u>::reserveCapacity(unsigned int)+40 <size>: 5358380 <Avg>: 4564 <caller>: alloc_small+208 <size>: 4160560 <Avg>: 8110 <caller>: WTF::Vector<unsigned int, 0u>::reserveCapacity(unsigned int)+56 <size>: 3780004 <Avg>: 63000 <caller>: png_malloc+72 <size>: 1827334 <Avg>: 3071 <caller>: gmem.c:152(IA__g_malloc0+72) <size>: 1706851 <Avg>: 393 <caller>: KJS::HashTable::createTable() const+32 <size>: 1471404 <Avg>: 15169 <caller>: WTF::fastZeroedMalloc(unsigned int)+12 <size>: 1418356 <Avg>: 551 <caller>: WebCore::TextCodecLatin1::decode(char const*, unsigned int, bool, bool, bool&)+32 <size>: 1330110 <Avg>: 11667 <caller>: __gconv_open+1344 <size>: 1305600 <Avg>: 32640 <caller>: WebCore::String::append(WebCore::String const&)+68 <size>: 1293644 <Avg>: 869 <caller>: sqlite3MallocRaw+48 <size>: 1038129 <Avg>: 259 <caller>: WTF::Vector<unsigned short, 0u>::reserveCapacity(unsigned int)+56 <size>: 995870 <Avg>: 9575 <caller>: WebCore::GlyphPageTreeNode::initializePage(WebCore::FontData const*, unsigned int)+448 <size>: 995104 <Avg>: 2056 <caller>: WebCore::StringImpl::create(unsigned short const*, unsigned int)+116 <size>: 816884 <Avg>: 32 <caller>: WebCore::StringImpl::create(unsigned short const*, unsigned int)+80 <size>: 510200 <Avg>: 20 <caller>: cairo-scaled-font.c:1796(_cairo_scaled_glyph_lookup+248) <size>: 426720 <Avg>: 96 <caller>: GIFImageReader::do_lzw(unsigned char const*)+760 <size>: 368730 <Avg>: 8194 <caller>: FcPatternObjectAddWithBinding+60 <size>: 365600 <Avg>: 32 <caller>: WTF::Vector<WebCore::RGBA32Buffer, 0u>::reserveCapacity(unsigned int)+60 <size>: 363456 <Avg>: 768 <caller>: WebCore::FontCache::getFontDataForCharacters(WebCore::Font const&, unsigned short const*, int)+36 <size>: 363424 <Avg>: 1108 <caller>: sqlite3Realloc+60 <size>: 292492 <Avg>: 552 <caller>: WebCore::JPEGImageDecoder::setData(WebCore::SharedBuffer*, bool)+112 <size>: 248920 <Avg>: 1016 <caller>: WebCore::GlyphPageTreeNode::initializePage(WebCore::FontData const*, unsigned int)+1172 <size>: 211768 <Avg>: 2056 <caller>: strdup+24 <size>: 207135 <Avg>: 36 <caller>: WebCore::Cache::requestResource(WebCore::DocLoader*, WebCore::CachedResource::Type, WebCore::KURL const&, WebCore::String const&, bool)+548 <size>: 187680 <Avg>: 240 <caller>: WebCore::StringImpl::create(char const*, unsigned int)+108 <size>: 185274 <Avg>: 147 <caller>: GIFImageReader::read(unsigned char const*, unsigned int, WebCore::GIFImageDecoder::GIFQuery, unsigned int)+3284 <size>: 184365 <Avg>: 4097 <caller>: GIFImageReader::read(unsigned char const*, unsigned int, WebCore::GIFImageDecoder::GIFQuery, unsigned int)+3264 <size>: 184365 <Avg>: 4097 <caller>: WebCore::GIFImageDecoder::setData(WebCore::SharedBuffer*, bool)+112 <size>: 136000 <Avg>: 320 <caller>: alloc_large+96 <size>: 135960 <Avg>: 586 <caller>: KJS::UString::Rep::create(unsigned short*, int)+24 <size>: 127200 <Avg>: 48 <caller>: FcPatternObjectInsertElt+176 <size>: 126720 <Avg>: 256 <caller>: png_create_struct_2+108 <size>: 116560 <Avg>: 620 <caller>: GIFImageReader::read(unsigned char const*, unsigned int, WebCore::GIFImageDecoder::GIFQuery, unsigned int)+1912 <size>: 101304 <Avg>: 255 <caller>: WebCore::FontCache::getCachedFontData(WebCore::FontPlatformData const*)+120 <size>: 91964 <Avg>: 1108 <caller>: WebCore::Text::createWithLengthLimit(WebCore::Document*, WebCore::String const&, unsigned int&, unsigned int)+312 <size>: 86476 <Avg>: 52 <caller>: gmem.c:132(IA__g_malloc+64) <size>: 79287 <Avg>: 22 <caller>: WebCore::StringImpl::StringImpl(unsigned short const*, unsigned int, unsigned int)+48 <size>: 72278 <Avg>: 68 <caller>: /home/ir2daily/source-root/freetype2/src/base/ftutil.c:77(ft_mem_qalloc+24) <size>: 70354 <Avg>: 413 <caller>: WebCore::CachedImage::data(WTF::PassRefPtr<WebCore::SharedBuffer>, bool)+424 <size>: 62240 <Avg>: 80 <caller>: gmem.c:171(IA__g_realloc+76) <size>: 57080 <Avg>: 50 <caller>: cairo-hash.c:334(_cairo_hash_table_resize+128) <size>: 56656 <Avg>: 602 <caller>: WebCore::GlyphPageTreeNode::getChild(WebCore::FontData const*, unsigned int)+80 <size>: 50644 <Avg>: 44 On Thu, Sep 11, 2008 at 4:39 PM, Marco Barisione < [EMAIL PROTECTED]> wrote: > Il giorno mer, 10/09/2008 alle 13.26 +0530, zaheer ahmad ha scritto: > > In the linux Gtk port, with Webkit revision 33493, i see that the > > resource handles (curl backend) never get released after completing > > the data transfer for that request.
