Preparing for 2.12.0

WebkitGtk+ 2.12.0 will be the next release in the stable series (following 2.10.x). We should merge not overly intrusive patches that improve stability or performance, fix build issues, etc. We branched at r 196806 (19/02/16).

When filing bugs (​http://bugs.webkit.org) against stable release, please prefix them with "[GTK] [Stable]" to ensure they are addressed with high priority. Also, running a debug build and including stack traces is highly encouraged. (Don't use "[Stable]" if the bug also applies to master, though.)

To get the stable branch code, simply check out ​http://svn.webkit.org/repository/webkit/releases/WebKitGTK/webkit-2.12

Over the next few weeks we'll be merging important fixes into the branch, so be sure to stay up to date. Thanks for your help!

Proposed merges for 2.12.5

• ​https://bugs.webkit.org/show_bug.cgi?id=161029 [DFG] Should not fixup AnyIntUse in 32_64
  Backported version: ​https://github.com/annulen/webkit/commit/73bcc7a95.
• ​https://bugs.webkit.org/show_bug.cgi?id=161494 ​https://trac.webkit.org/changeset/202940 Followup to r202939.

Proposed merges for 2.12.4

• ​https://trac.webkit.org/changeset/203446 JSC JIT Broken on ARMv7 Traditional (without Thumb2)
• ​https://bugs.webkit.org/show_bug.cgi?id=158107 [GTK][Stable]: Merge r201072 and r201216 (and some misc gardening of accessibility tests)
  This change brings us into better compliance with a couple of W3C specs and fixes several bugs in which the accessible name of objects was missing or broken. Because Orca doesn't always know when/if the accessible name is broken, having this fix is desirable.
  N.B. Stable-branch-compatible patch attached.
• ​https://bugs.webkit.org/show_bug.cgi?id=158109 [GTK][Stable]: Merge r201087
  The reason the meter.html test was failing is due to lack of implementation. Also, as part of the fix, we are now exposing the aria-valuetext value which had not previously been exposed. Because aria-valuetext is used on a number of ARIA widget roles, and because meters should be accessible, this fix is desirable.
  N.B. Stable-branch-compatible patch attached.
• ​https://trac.webkit.org/changeset/201595 [Wayland] PlatformDisplayWayland destructor is super crashy
• ​https://trac.webkit.org/changeset/196886 Remove arrowfunction test cases that rely on arguments variable in jsc
• ​http://trac.webkit.org/changeset/199017 Regression(r196145): Crash in getOwnPropertyDescriptor on ​​http://www.history.com/shows/vikings
• ​https://trac.webkit.org/r203976 REGRESSION (r196383): Drop down CSS menus not working on cnet.com, apmex.com
• ​http://trac.webkit.org/changeset/204250 [GTK] Bad performance in accelerated compositing mode with the modesetting intel driver and DRI3 enabled

Proposed merges for 2.12.3

• ​https://trac.webkit.org/changeset/200188 AX: [ATK] We need to be smarter about flattening and the accessible text implementation
• ​https://bugs.webkit.org/show_bug.cgi?id=153956 REGRESSION(r196222): [AX][GTK] accessibility/gtk/caret-offsets.html failing
  (The reason for including this is because in the process of fixing the Layout-Test-only failure, I discovered and fixed a bug in the caret-moved event for list items which would cause Orca to speak the wrong character during caret navigation.)
• ​http://trac.webkit.org/changeset/201163 [GStreamer] unrelated codecs required to play videos
• ​https://trac.webkit.org/changeset/197886 [cmake] Fixed All-in-One build
• ​https://trac.webkit.org/changeset/200677 [GTK] accessibility/aria-readonly.html is failing
  Fixing this failing test was done by adding support for ATK_STATE_READ_ONLY, ATK_STATE_CHECKABLE, and correcting some bugs associated with the exposure of ATK_STATE_EDITABLE. Because Orca doesn't always know when/if the accessible state set isn't quite right, having this fix is desirable.

Proposed merges for 2.12.2

• ​https://trac.webkit.org/changeset/199715 [GTK] accessibility/gtk/entry-and-password.html is failing since r194847.
  (For the release notes, what was fixed is bogus accessibility events causing Orca to echo key presses instead of speaking the inserted, and by default obscured, characters in password fields.)
• ​http://trac.webkit.org/changeset/199703 [GTK] Possible off-by-one in hyphenation code
• ​https://trac.webkit.org/changeset/200046 [GTK] Crashes if DISPLAY is unset
• ​https://trac.webkit.org/changeset/200125 [GTK] Fails to build randomly when generating LLIntDesiredOffsets.h

Proposed merges for 2.12.1

• ​http://trac.webkit.org/changeset/198701 RenderImage::repaintOrMarkForLayout fails when the renderer is detached.
• ​https://trac.webkit.org/changeset/198919 Fails to build in Linux / PowerPC due to different ucontext_t definition (follow-up for it is ​https://bugs.webkit.org/show_bug.cgi?id=156337)
• ​https://trac.webkit.org/changeset/198945 [JSC] Missing PATH_MAX definition
• ​https://trac.webkit.org/changeset/199229 AX: [ATK] Crash getting text under element in CSS table
• ​https://bugs.webkit.org/show_bug.cgi?id=156533 Fix build in glibc-based BSD systems

Proposed merges for 2.11.92

• ​http://trac.webkit.org/changeset/197716 Crash in WebCore::RenderElement::containingBlockForObjectInFlow
• ​https://bugs.webkit.org/show_bug.cgi?id=146041 [GTK] Reimplement webkit_web_context_clear_cache functionality.
• ​http://trac.webkit.org/changeset/198058 [GTK][Mac] Don't force ENABLE_INTROSPECTION=OFF on Mac

• ​http://trac.webkit.org/changeset/198127 Enable GSS-Negotiate support in libsoup

Proposed merges for 2.11.91

• ​https://trac.webkit.org/changeset/196962 Fix build and implement functions to retrieve registers on FreeBSD

How to add a webkit-2.12 branch to existing git-svn clone

If you have already cloned ​git://git.webkit.org/WebKit.git, it only contains a git-svn clone of the svn trunk. To add webkit-2.12 branch to there, add a new remote to .git/config:

[svn-remote "webkit-2.12"]
    url = http://svn.webkit.org/repository/webkit/releases/WebKitGTK/webkit-2.12
    fetch = :refs/remotes/git-svn-webkit-2.12

and run the following commands:

git svn fetch webkit-2.12 -r 196806
git branch webkit-2.12 git-svn-webkit-2.12
git checkout webkit-2.12
git svn rebase
