[tor-browser/tor-browser-60.6.1esr-8.5-1] Bug 27503: Disabling accessibility on Windows breaks screen readers
by gk＠torproject.org 11 Apr '19

11 Apr '19

commit f5f845f5fe14b5085f919ba46ec092b14c7fcb11 Author: Richard Pospesel <richard(a)torproject.org> Date: Tue Apr 2 17:33:09 2019 -0700 Bug 27503: Disabling accessibility on Windows breaks screen readers This patch is merely an application of the current accessibility fixes in Mozilla 1520177 ( https://bugzilla.mozilla.org/show_bug.cgi?id=1520177 ). It replaces the RT_MANIFEST symbol (defined in windows headers we don't include) with the integer constant 24 to avoid includes confusion, updates the IA2Marshall.rc file to explicitly include the dll manifest and it adds some additional include directories previously excluded when building with the mingw toolchain. With this patch applied, the NVDA screen reader can now read webpage contents, though navigation is still broken. --- accessible/interfaces/ia2/IA2Marshal.rc | 1 + toolkit/library/moz.build | 2 +- toolkit/library/xulrunner.rc | 4 ++-- 3 files changed, 4 insertions(+), 3 deletions(-) diff --git a/accessible/interfaces/ia2/IA2Marshal.rc b/accessible/interfaces/ia2/IA2Marshal.rc index b120abce744c..4fd86ddd2ab5 100644 --- a/accessible/interfaces/ia2/IA2Marshal.rc +++ b/accessible/interfaces/ia2/IA2Marshal.rc @@ -3,3 +3,4 @@ * file, You can obtain one at http://mozilla.org/MPL/2.0/. */ 1 typelib IA2Typelib.tlb +2 24 IA2Marshal.dll.manifest diff --git a/toolkit/library/moz.build b/toolkit/library/moz.build old mode 100644 new mode 100755 index b0df6b98b91f..aeb850bdefba --- a/toolkit/library/moz.build +++ b/toolkit/library/moz.build @@ -45,7 +45,7 @@ def Libxul(name): if CONFIG['OS_ARCH'] == 'WINNT' and CONFIG['ACCESSIBILITY']: LOCAL_INCLUDES += ['!/accessible/interfaces/gecko/'] - if CONFIG['OS_ARCH'] == 'WINNT' and CONFIG['CC_TYPE'] not in ('clang', 'gcc'): + if CONFIG['OS_ARCH'] == 'WINNT': LOCAL_INCLUDES += [ '/widget/windows', '/xpcom/base', diff --git a/toolkit/library/xulrunner.rc b/toolkit/library/xulrunner.rc index e2adca6e2f1f..29a20c3afc11 100755 --- a/toolkit/library/xulrunner.rc +++ b/toolkit/library/xulrunner.rc @@ -6,8 +6,8 @@ #include "widget.rc" #ifdef ACCESSIBILITY 1 typelib IGeckoCustom.tlb -64 RT_MANIFEST IAccessible64.manifest +64 24 IAccessible64.manifest #ifndef HAVE_64BIT_BUILD -32 RT_MANIFEST IAccessible32.manifest +32 24 IAccessible32.manifest #endif #endif

[snowflake/master] Fix for proxy deadlock bug
by cohosh＠torproject.org 11 Apr '19

11 Apr '19

commit c28c8ca489633aae2d9b9dbea0e781ca5e44cc66 Author: Cecylia Bocovich <cohosh(a)torproject.org> Date: Sat Mar 30 12:19:29 2019 -0400 Fix for proxy deadlock bug This is a fix for the proxy-go deadlock bug (ticket #25688). The assumption that OnIceComplete is always followed by a successful connection where OnDataChannel has been called turns out not to occur in practice. OnICEComplete looks like it is being deprecated in other libraries anyway, so it's safer to just remove it. --- proxy-go/snowflake.go | 42 ++++++++++++++++-------------------------- 1 file changed, 16 insertions(+), 26 deletions(-) diff --git a/proxy-go/snowflake.go b/proxy-go/snowflake.go index 2e8fe20..aeb9f51 100644 --- a/proxy-go/snowflake.go +++ b/proxy-go/snowflake.go @@ -259,8 +259,6 @@ func datachannelHandler(conn *webRTCConn, remoteAddr net.Addr) { // Installs an OnDataChannel callback that creates a webRTCConn and passes it to // datachannelHandler. func makePeerConnectionFromOffer(sdp *webrtc.SessionDescription, config *webrtc.Configuration) (*webrtc.PeerConnection, error) { - errChan := make(chan error) - answerChan := make(chan struct{}) pc, err := webrtc.NewPeerConnection(config) if err != nil { @@ -269,9 +267,6 @@ func makePeerConnectionFromOffer(sdp *webrtc.SessionDescription, config *webrtc. pc.OnNegotiationNeeded = func() { panic("OnNegotiationNeeded") } - pc.OnIceComplete = func() { - answerChan <- struct{}{} - } pc.OnDataChannel = func(dc *webrtc.DataChannel) { log.Println("OnDataChannel") @@ -310,30 +305,25 @@ func makePeerConnectionFromOffer(sdp *webrtc.SessionDescription, config *webrtc. } log.Println("sdp offer successfully received.") - go func() { - log.Println("Generating answer...") - answer, err := pc.CreateAnswer() // blocking - if err != nil { - errChan <- err - return - } - err = pc.SetLocalDescription(answer) - if err != nil { - errChan <- err - return - } - }() + log.Println("Generating answer...") + answer, err := pc.CreateAnswer() + // blocks on ICE gathering. we need to add a timeout if needed + // not putting this in a separate go routine, because we need + // SetLocalDescription(answer) to be called before sendAnswer + if err != nil { + pc.Destroy() + return nil, err + } - // Wait until answer is ready. - select { - case err = <-errChan: + if answer == nil { + pc.Destroy() + return nil, fmt.Errorf("Failed gathering ICE candidates.") + } + + err = pc.SetLocalDescription(answer) + if err != nil { pc.Destroy() return nil, err - case _, ok := <-answerChan: - if !ok { - pc.Destroy() - return nil, fmt.Errorf("Failed gathering ICE candidates.") - } } return pc, nil }
