1.53.1
Version 1.53.1 - Improvements to garbage collection performance. Read for more information: https://feaneron.com/2018/04/20/the-infamous-gnome-shell-memory-leak/ - Now, when building a class from a UI template file (using the `Template` parameter passed to `GObject.registerClass()`, for example) signals defined in the UI template file will be automatically connected. - As an experimental feature, we now offer a flatpak built with each GJS commit, including branches. You can use this to test your apps with a particular GJS branch before it is merged. Look for it in the "Artifacts" section of the CI pipeline. - Closed bugs and merge requests: * Tweener: Add min/max properties [!67, Jason Hicks] * `ARGV` encoding issues [#22, !108, Evan Welsh] * Make GC much more aggressive [#62, !50, Giovanni Campagna, Georges Basile Stavracas Neto, Philip Chimento] * Queue GC when a GObject reference is toggled down [#140, !114, !127, Georges Basile Stavracas Neto] * overrides: support Gtk template callbacks [!124, Andy Holmes] * Ensure not to miss the force_gc flag [#150, !132, Carlos Garnacho] * Create a flatpak on CI [#153, !135, Claudio André] * Readme update [!138, Claudio André] -
1.52.3
Version 1.52.3 - Closed bugs and merge requests: * Include calc.js example from Seed [!130, William Barath, Philip Chimento] * CI: Un-pin the Fedora Docker image [#141, !131, Claudio André] * Reduce overhead of wrapped objects [#142, !121, Carlos Garnacho, Philip Chimento] * Various CI changes [!134, !136, Claudio André] -
1.52.2
Version 1.52.2 - This is an unscheuled release in order to revert a commit that causes a crash on exit, with some Cairo versions. - Closed bugs and merge requests: * CI: pinned Fedora to old tag [!119, Claudio André] * heapgraph.py: adjust terminal output style [!120, Andy Holmes] * CI: small tweaks [!123, Claudio André] * Warn about compilation warnings [!125, Claudio André] * Miscellaneous commits [Philip Chimento, Jason Hicks]

1.52.1
Version 1.52.1 - This version has more changes than would normally be expected from a stable version. The intention of 1.52.1 is to deliver a version that runs cleaner under performance tools, in time for the upcoming GNOME Shell performance hackfest. We also wanted to deliver a stable CI pipeline before branching GNOME 3.28 off of master. - Claudio André's work on the CI pipeline deserves a spotlight. We now have test jobs that run linters, sanitizers, Valgrind, and more; the tests are run on up-to-date Docker images; and the reliability errors that were plaguing the test runs are solved. - In addition to System.dumpHeap(), you can now dump a heap from a running Javascript program by starting it with the environment variable GJS_DEBUG_HEAP_OUTPUT=some_name, and sending it SIGUSR1. - heapgraph.py is a tool in the repository (not installed in distributions) for analyzing and graphing heap dumps, to aid with tracking down memory leaks. - The linter CI jobs will compare your branch against GNOME/gjs@master, and fail if your branch added any new linter errors. There may be false positives, and the rules configuration is not perfect. If that's the case on your merge request, you can skip the appropriate linter job by adding the text "[skip (linter)]" in your commit message: e.g., "[skip cpplint]". - We welcomed first merge requests from several new contributors for this release. - Closed bugs and merge requests: * Crash when resolving promises if exception is pending [#18, !95, Philip Chimento] * gjs_byte_array_get_proto(JSContext*): assertion failed: (((void) "gjs_" "byte_array" "_define_proto() must be called before " "gjs_" "byte_array" "_get_proto()", !v_proto.isUndefined())) [#39, !92, Philip Chimento] * Tools for examining heap graph [#116, !61, !118, Andy Holmes, Tommi Komulainen, Philip Chimento] * Run analysis tools to prepare for release [#120, !88, Philip Chimento] * Add support for passing flags to Gio.DBusProxy in makeProxyWrapper [#122, !81, Florian Müllner] * Cannot instantiate Cairo.Context [#126, !91, Philip Chimento] * GISCAN GjsPrivate-1.0.gir fails [#128, !90, Philip Chimento] * Invalid read of g_object_finalized flag [#129, !117, Philip Chimento] * Fix race condition in coverage file test [#130, !99, Philip Chimento] * Linter jobs should only fail if new lint errors were added [#133, !94, Philip Chimento] * Disable all tests that depends on X if there is no XServer [#135, !109, Claudio André] * Pick a different C++ linter [#137, !102, Philip Chimento] * Create a CI test that builds using autotools only [!74, Claudio André] * CI: enable ASAN [!89, Claudio André] * CI: disable static analysis jobs using the commit message [!93, Claudio André] * profiler: Don't assume layout of struct sigaction [!96, James Cowgill] * Valgrind [!98, Claudio André] * Robustness of CI [!103, Claudio André] * CI: make a separate job for installed tests [!106, Claudio André] * Corrected Markdown format and added links to JHBuild in setup guide for GJS [!111, Avi Zajac] * Update tweener.js -- 48 eslint errors fixed [!112, Karen Medina] * Various maintenance [!100, !104, !105, !107, !110, !113, !116, Claudio André, Philip Chimento] -
1.52.0
Version 1.52.0 - No changes from 1.51.92 except for the continuous integration configuration. - Closed bugs and merge requests: * Various CI improvements [!84, !85, !86, !87, Claudio André]
-
1.51.92
Version 1.51.92 - Closed bugs and merge requests: * abort if we are called back in a non-main thread [#75, !72, Philip Chimento] * 3.27.91 build failure on debian/Ubuntu [#122, !73, Tim Lunn] * Analyze project code quality with Code Climate inside CI [#10, !77, Claudio André] * Various CI improvements [!75, !76, !79, !80, !82, !83, Claudio André] -
1.51.91
Version 1.51.91 - Promises now resolve with a higher priority, so asynchronous code should be faster. [Jason Hicks] - Closed bugs and merge requests: * New build 'warnings' [#117, !62, !63, Claudio André, Philip Chimento] * Various CI maintenance [!64, !65, !66, Claudio André, Philip Chimento] * profiler: Don't include alloca.h when disabled [!69, Ting-Wei Lan] * GNOME crash with fatal error "Finalizing proxy for an object that's scheduled to be unrooted: Gio.Subprocess" in gjs [#26, !70, Philip Chimento] -
1.51.90
Version 1.51.90 - Note that all the old Bugzilla bug reports have been migrated over to GitLab. - GJS now, once again, includes a profiler, which outputs files that can be read with sysprof. To use it, simply run your program with the environment variable GJS_ENABLE_PROFILER=1 set. If your program is a JS script that is executed with the interpreter, you can also pass --profile to the interpreter. See "gjs --help" for more info. - New API: For programs that want more control over when to start and stop profiling, there is new API for GjsContext. When you create your GjsContext there are two construct-only properties available, "profiler-enabled" and "profiler-sigusr2". If you set profiler-sigusr2 to TRUE, then the profiler can be started and stopped while the program is running by sending SIGUSR2 to the process. You can also use gjs_context_get_profiler(), gjs_profiler_set_filename(), gjs_profiler_start(), and gjs_profiler_stop() for more explicit control. - New API: GObject.signal_connect(), GObject.signal_disconnect(), and GObject.signal_emit_by_name() are now available in case a GObject-derived class has conflicting connect(), disconnect() or emit() methods. - Closed bugs and merge requests: * Handle 0-valued GType gracefully [#11, !10, Philip Chimento] * Profiler [#31, !37, Christian Hergert, Philip Chimento] * Various maintenance [!40, !59, Philip Chimento, Giovanni Campagna] * Rename GObject.Object.connect/disconnect? [#65, !47, Giovanni Campagna] * Better debugging output for uncatchable exceptions [!39, Simon McVittie] * Update Docker images and various CI maintenance [!54, !56, !57, !58, Claudio André] * Install GJS suppression file for Valgrind [#2, !55, Philip Chimento] -
1.50.4
Version 1.50.4 - Closed bugs and merge requests: * Gnome Shell crash with places-status extension when you plug an USB device [#33, !38, Philip Chimento] -
1.50.3
Version 1.50.3 - GJS will now log a warning when a GObject is accessed in Javascript code after the underlying object has been freed in C. (This used to work most of the time, but crash unpredictably.) We now prevent this situation which, is usually caused by a memory management bug in the underlying C library. - Closed bugs and merge requests: * Add checks for GObjects that have been finalized [#21, #23, !25, !28, !33, Marco Trevisan] * Test "Cairo context has methods when created from a C function" fails [#27, !35, Valentín Barros] * Various fixes from the master branch for rare crashes [Philip Chimento] -
1.51.4
Version 1.51.4 - We welcomed code and documentation from several new contributors in this release! - GJS will now log a warning when a GObject is accessed in Javascript code after the underlying object has been freed in C. (This used to work most of the time, but crash unpredictably.) We now prevent this situation which, is usually caused by a memory management bug in the underlying C library. - APIs exposed through GObject Introspection that use the GdkAtom type are now usable from Javascript. Previously these did not work. On the Javascript side, a GdkAtom translates to a string, so there is no Gdk.Atom type that you can access. The special atom GDK_NONE translates to null in Javascript, and there is also no Gdk.NONE constant. - The GitLab CI tasks have continued to gradually become more and more sophisticated. - Closed bugs and merge requests: * Add checks for GObjects that have been finalized [#21, #23, !22, !27, Marco Trevisan] * Fail static analyzer if new warnings are found [!24, Claudio André] * Run code coverage on GitLab [!20, Claudio André] * Amend gtk.js and add gtk-application.js with suggestion [!32, Andy Holmes] * Improve GdkAtom support that is blocking clipboard APIs [#14, !29, makepost] * Test "Cairo context has methods when created from a C function" fails [#27, !35, Valentín Barros] * Various CI improvements [#6, !26, !34, Claudio André] * Various maintenance [!23, !36, Philip Chimento] -
1.51.3
Version 1.51.3 - This release was made from an earlier state of master, before a breaking change was merged, while we decide whether to revert that change or not. - Closed bugs and merge requests: * CI improvements on GitLab [!14, !15, !19, Claudio André] * Fix CI build on Ubuntu [#16, !18, !21, Claudio André, Philip Chimento]
-
1.51.2
Version 1.51.2 - Version 1.51.1 was skipped. - The home of GJS is now at GNOME's GitLab instance: https://gitlab.gnome.org/GNOME/gjs From now on we'll be taking GitLab merge requests instead of Bugzilla patches. If you want to report a bug, please report it at GitLab. - Closed bugs and merge requests: * Allow throwing GErrors from JS virtual functions [#682701, Giovanni Campagna] * [RFC] bootstrap system [#777724, Jasper St. Pierre, Philip Chimento] * Fix code coverage (and refactor it to take advantage of mozjs52 features) [#788166, !1, !3, Philip Chimento] * Various maintenance [!2, Philip Chimento] * Get GitLab CI working and various improvements [#6, !7, !9, !11, !13, Claudio André] * Add build status badge to README [!8, Claudio André] * Use Docker images for CI [!12, Claudio André] - Some changes in progress to improve garbage collection when signals are disconnected. See bug #679688 for more information [Giovanni Campagna] -
1.50.2
Version 1.50.2 - Closed bugs and merge requests: * tweener: Fix a couple of warnings [!5, Florian Müllner] * legacy: Allow ES6 classes to inherit from abstract Lang.Class class [!6, Florian Müllner] - Minor bugfixes [Philip Chimento] -
1.50.1
Version 1.50.1 - As a debugging aid, gjs_dumpstack() now works even during garbage collection. - Code coverage tools did not work so well in the last few 1.49 releases. The worst problems are now fixed, although even more improvements will be released in the next unstable version. Fixes include: * Specifing prefixes for code coverage files now works again * Code coverage now works on lines inside ES6 class definitions * The detection of which lines are executable has been improved a bit
-
1.50.0
Version 1.50.0 - Closed bugs: * Relicense coverage.cpp and coverage.h to the same license as the rest of GJS [#787263, Philip Chimento; thanks to Dominique Leuenberger for pointing out the mistake] -
1.48.7
Version 1.48.7 - Backported some memory leak fixes from 1.49.92 - Backported refactor of closure invalidation code from 1.49.92
-
1.49.92
Version 1.49.92 - It's now possible to build GJS with sanitizers (ASan and UBSan) enabled; add "--enable-asan" and "--enable-ubsan" to your configure flags. This has already caught some memory leaks. - There's also a "make check-valgrind" target which will run GJS's test suite under Valgrind to catch memory leaks and threading races. - Many of the crashes in GNOME 3.24 were caused by GJS's closure invalidation code which had to change from the known-working state in 1.46 because of changes to SpiderMonkey's garbage collector. This code has been refactored to be less complicated, which will hopefully improve stability and debuggability. - Closed bugs: * Clean up the idle closure invalidation mess [#786668, Philip Chimento] * Add ASan and UBSan to GJS [#783220, Claudio André] * Run analysis tools on GJS to prepare for release [#786995, Philip Chimento] * Fix testLegacyGObject importing the GTK overrides [#787113, Philip Chimento] - Docs tweak [Philip Chimento]
-
1.49.91
Version 1.49.91 - Deprecation: The private "__name__" property on Lang.Class instances is now discouraged. Code should not have been using this anyway, but if it did then it should use the "name" property on the class (this.__name__ should become this.constructor.name), which is compatible with ES6 classes. - Closed bugs: * Use ES6 classes [#785652, Philip Chimento] * A few fixes for stack traces and error reporting [#786183, Philip Chimento] * /proc/self/stat is read for every frame if GC was not needed [#786017, Benjamin Berg] - Build fix [Philip Chimento] -
1.49.90
Version 1.49.90 - New API: GObject.registerClass(), intended for use with ES6 classes. When defining a GObject class using ES6 syntax, you must call GObject.registerClass() on the class object, with an optional metadata object as the first argument. (The metadata object works exactly like the meta properties from Lang.Class, except that Name and Extends are not present.) Old: var MyClass = new Lang.Class({ Name: 'MyClass', Extends: GObject.Object, Signals: { 'event': {} }, _init(props={}) { this._private = []; this.parent(props); }, }); New: var MyClass = GObject.registerClass({ Signals: { 'event': {} }, }, class MyClass extends GObject.Object { _init(props={}) { this._private = []; super._init(props); } }); It is forward compatible with the following syntax requiring decorators and class fields, which are not in the JS standard yet: @GObject.registerClass class MyClass extends GObject.Object { static [GObject.signals] = { 'event': {} } _init(props={}) { this._private = []; super._init(props); } } One limitation is that GObject ES6 classes can't have constructor() methods, they must do any setup in an _init() method. This may be able to be fixed in the future. - Closed bugs: * Misc 1.49 and mozjs52 enhancements [#785040, Philip Chimento] * Switch to native promises [#784713, Philip Chimento] * Can't call exports using top-level variable toString [#781623, Philip Chimento] * Properties no longer recognized when shadowed by a method [#785091, Philip Chimento, Rico Tzschichholz] * Patch: backport of changes required for use with mozjs-55 [#785424, Luke Jones]
