* Fix uninitialized memory bug in the SkGlyphCache.Gravatar herb2015-03-05
| | | | | | | | | | | | | | | | | | | The core of the problem is that the system is asked to lookup the metrics for a character with id == 0. This causes a hit in the fCharToGlyphHash matching the sentinel glyph. This happens because fCharToGlpyhHash is initialized with all zeros, therefore, the fID is zero matching the char with id == 0. The fAdvanceX field of the sentinel glyph is in fact not initialized. The bigger question is now did a zero character get passed to getUnicharMetrics? The breaking code is basically as follows: wchar_t glyph = L'S'; paint.measureText(&glyph, 2); This get mischaracterized as a utf8 string instead of a utf16(?) string. Because of the little endian ordering, this is the character string 'L' '\0'. Since the size of the original string is two bytes (but a single character) the '\0' is treated as its own character and past to getUnicharMetrics. TEST: On windows failed using DrMemory. With this change does not fail. BUG=463204 Review URL: https://codereview.chromium.org/977063002

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | https://codereview.chromium.org/939123002/) Reason for revert: This actually *does* change the public API - fID is now private, and it was being used on Android. See https://android-build.storage.googleapis.com/builds/git_master-skia-linux-volantis-userdebug/1751533/5242b865d3e9bebc650c9b326dfa9d68c8bd1f59562bf32b85301fb984dc8b26/logs/build.log?Signature=Q0el9M4kTu1KQ8u02KX9TH1Pa22y9BkDK1IW%2B9OeJJNfrDEVzLXAz0XQ%2BHHQM8xVjft06jZJva1V8InZmgjcOk6PdZQbQW6XwwsHLKsbpbAE48iTWH3AlJAAoTtj9cifzgeHW8g80IcVxwHXmINRER%2BLPz3eHGisgfTTFUoWYCc%3D&GoogleAccessId=701025073339-mqn0q2nvir9iurm6q5d00tdv7blbgvjr%40developer.gserviceaccount.com&Expires=1424786471 : In file included from frameworks/base/libs/hwui/tests/../font/Font.cpp:26:0: external/skia/src/core/SkGlyph.h: In member function 'android::uirenderer::CachedGlyphInfo* android::uirenderer::Font::cacheGlyph(const SkPaint*, glyph_t, bool)': external/skia/src/core/SkGlyph.h:157:17: error: 'uint32_t SkGlyph::fID' is private uint32_t fID; ^ frameworks/base/libs/hwui/tests/../font/Font.cpp:482:39: error: within this context newGlyph->mGlyphIndex = skiaGlyph.fID; We need to update Android in order to hide fID.

* Move distance field generation to the glyph cache.Gravatar commit-bot@chromium.org2014-04-14
| | | | | | | | | | | | | | Distance fields are currently created in GrTextStrike, which is the wrong place. This moves that to the glyph cache where it belongs. As part of my testing, I found that when we fall back to paths in the GrDistanceFieldTextContext it was not scaling them properly, so that's fixed in here too.
