Latest upstream release of Mir0.1.6 (lp:~mir-team/mir/development-branch r1433)

[Daniel van Vugt (vanvugt)]

The diff to tagged release 0.1.6 is good. Only changelog differs.

Only mentions of last minute bugs are missing from changelog:
  bug 1285955
  bug 1207312

I would also recommend not cluttering the changelog with details of internal changes that users of Mir won't ever need to understand. e.g. All but one of these are meaningless to the public Mir SDK so should not be mentioned;

396 + - config, frontend: remove force_threads_to_unblock_callback()
397 + - Protect input region member of surface data, hold mutex to access
398 + hidden member.
399 + - config: ConfigurationOptions::default_ipc_threads can be a constant.
400 + - debian: Provide platform packages managed with dpkg alternatives.
401 + - Add the ability to load device traces, both udev and ioctls, in the
402 + UdevEnvironment test helper.
403 + - test_client_input.cpp: Remove unused global "mir_test_socket".
404 + - Sundry improvements to mir::udev.

That's not all. I just picked it as an example. Only line 400 would qualify as meaningful to anyone else, so release notable.

wasn't sure to include bug 1285955 as fixed, as the mp is more of a temp workaround - but i'll include that.

I'm torn about condensing the changelog - i prefer the detail. But, happy to conform to convention.
I'll take one more scrub, but then let's move on getting this in.

[kevin gunn (kgunn72)]

Did you test your feature/code change/bug fix ? what device(s) ?
dev branch ci testing across i386, amd64 & arm/nexus4

Did you break mir server API or ABI and have the relevant bumps to .so and debian docs been made ?
yes - libmirserver, updates have been made

Did you break mir client API or ABI and have you followed up with the known clients & announced on mir-devel mailing list ?
yes

Don't forget to check on Xorg in the case of client API break
does not break Xorg/xmir

[Daniel van Vugt (vanvugt)]

For bug 1285955 the "workaround" is the closest thing to a fix the Mir project will ever need. So that's definitely Fix Released for Mir in 0.1.6.

[Daniel van Vugt (vanvugt)]

I think the last commit should be reverted ("updated snapshot from mir-devel r1441"). Mir 0.1.6 is r1433. Nothing newer than that should be included until it's cooled down a bit as part of the 0.1.7 cycle.

review: Needs Fixing

[Daniel van Vugt (vanvugt)]

The post-0.1.6 changes I intentionally kept out of 0.1.6 because they're large and still carry some risk. So I'll keep those back to the 0.1.7 release.

Fix and clean up changelog

Mir 0.1.6
+ Two cherry picks from Mir 0.1.7 (one enhancement + one bug fix)
+ changelog additions.

[Daniel van Vugt (vanvugt)]

We should stop adding bits of Mir 0.1.7. There are large changes post-0.1.6 (that I wrote even) and it's safest if we let them cool down and mature some more over the weeks before entering distro.

you should not be landing anything on devel you would not instantly want in archive.
devel has been treated as sacred, devel was only created as a barrier for server changes. if you need to mature items, keep a feature branch and ask for testing help.

[Daniel van Vugt (vanvugt)]

Feature branches are the opposite of maturing code. In a feature branch, no one other than the author is using it on a daily basis. So the maturation (testing by multiple people) never even begins.

[Daniel van Vugt (vanvugt)]

The diff still looks correct, and accurately reflected in debian/changelog.

+mir (0.1.6-0ubuntu1) UNRELEASED; urgency=medium
+
+  * Cherry-picked from future release 0.1.7:
+    - Enhancement: options: Make it easier to customize DefaultConfiguration
+    - Bug fix: Don't pass a parameter to bash's popd command. It doesn't expect
+      one and will return an error from cross-compile-chroot.sh. (LP: #1287600)
+  * New upstream release 0.1.6 (https://launchpad.net/mir/+milestone/0.1.6)
+    - mirserver ABI bumped to 16.
+    - Server API changes:
+      . Report classes have moved to new namespaces/components. Please
+        consult the server headers.
+      . General clean-ups and virtual function changes affecting the ABI
+        (a rebuild is required for all shells).
+    - mirclient ABI unchanged, still at 7. Clients do not need rebuilding.
+    - Add new feature: Screen recording ("screencasting") as demonstrated by
+      the new mir-util "mirscreencast".
+    - debian: Provide platform packages managed with dpkg alternatives.
+    - Add new valgrind suppressions (mostly for armhf right now)
+    - tools: Add new libmirclientplatform.so to install_on_android.sh.
+    - Add "mir_demo_standalone_render_overlays", which is a free-standing
+      example of overlay support.
+    - Proper DisplayConfiguration for the AndroidDisplay to be better 
+      prepared for multi-monitor Android.
+    - Commenced/continued simplifying the surface class hierarchy: BasicSurface
+      has now absorbed SurfaceData.
+    - Dynamically load the client platform library.
+    - Bugs fixed:
+      . Exceptions thrown from within compositing threads were untraceable,
+        resulting in a bunch of undebuggable crash reports (LP: #1237332)
+      . Ensure we close drm device file descriptors on exec. (LP: #1284081)
+      . nested render_surfaces fails on N4 [std::exception::what: Failed to
+        compile vertex shader:] (LP: #1284597)
+      . examples: correct "fullscreen-surfaces" option. (LP: #1284554)
+      . Fix mutex data race reported by helgrind in integration test:
+        SwapperSwappingStress (LP: #1282886)
+      . scene: Return null snapshots for sessions without surfaces 
+        (LP: #1281728)
+      . tests: Address some raciness in
+        MesaDisplayTest.drm_device_change_event_triggers_handler. 
+        (LP: #1283085)
+      . tests: Suppress spurious memory errors occuring when running the
+        unit tests on armhf with valgrind. (LP: #1279438)
+      . Mir shows an old frame on client startup (for Mesa GL clients)
+        (LP: #1281938)
+      . tests: Add expectation to validate second SessionAuthorizer method
+        is called wit correct parameter. (LP: #1218436)
+      . Set field "current_format" when sending a display config to the
+        server. (LP: #1277343)
+      . Fix crash in android devices by working around a subtle threading
+        bug, use a dummy thead_local array to push the gl/egl context TLS 
+        into a region where the future wait code does not overwrite it. 
+        (LP: #1280086)
+      . compositor: calling SwitchingBundle::force_requests_to_complete()
+        can be a no-op when there are no requests. (LP: #1281145)
+      . tests: Don't emit an "add" uevent manually when adding a device
+        (LP: #1281146)
+      . config: reduce size of default RPC thread pool. (LP: #1233001)
+      . Clients freeze on startup if 10 or more are already running
+        (LP: #1267323)
+      . Fix Nexus 10 leaking FDs in the hwc prepare/set loop. (LP: #1278658)
+      . Parallelize page flipping with rendering of the next frame, fixing
+        stuttering observed in multi-monitor clone mode (LP: #1213801)
+      . Ubuntu trusty update "glm 0.9.5.1-1" broke Mir builds. Work around the
+        change. (LP: #1285955)
+      . Screencast feature by compositing to offscreen buffer (LP: #1207312)

+          and non-pure), explicitly declare it <code>override</code>
+          in the declaration of the derived class. Rationale: using
+          <code>override</code> allows the compiler to consistently
+          detect attempts to override methods that have been changed
+          or completely removed. It also makes it straightforward for
+          a reader to determine if a method is virtual or not.
