Version 1.55.91 --------------- - The problem of freezing while running the tests using GCC's sanitizers was determined to be a bug in GCC, which was fixed in GCC 9.0.1. - Closed bugs and merge requests: * gnome-sound-recorder crashes deep inside libgjs [#223, !266, Philip Chimento] * Various maintenance [!267, Philip Chimento] * wrapperutils: Define $gtype property as non-enumerable [!268, Philip Chimento] Version 1.55.90 --------------- - New JS API: It's now possible to call and implement DBus methods whose parameters or return types include file descriptor lists (type signature 'h'.) This involves passing or receiving a Gio.UnixFDList instance along with the parameters or return values. To call a method with a file descriptor list, pass the Gio.UnixFDList along with the rest of the parameters, in any order, the same way you would pass a Gio.Cancellable or async callback. For return values, things are a little more complicated, in order to avoid breaking existing code. Previously, synchronously called DBus proxy methods would return an unpacked GVariant. Now, but only if called with a Gio.UnixFDList, they will return [unpacked GVariant, Gio.UnixFDList]. This does not break existing code because it was not possible to call a method with a Gio.UnixFDList before, and the return value is unchanged if not calling with a Gio.UnixFDList. This does mean, unfortunately, that if you have a method with an 'h' in its return signature but not in its argument signatures, you will have to call it with an empty FDList in order to receive an FDList with the return value, when calling synchronously. On the DBus service side, when receiving a method call, we now pass the Gio.UnixFDList received from DBus to the called method. Previously, sync methods were passed the parameters, and async methods were passed the parameters plus the Gio.DBusInvocation object. Appending the Gio.UnixFDList to those parameters also should not break existing code. See the new tests in installed-tests/js/testGDBus.js for examples of calling methods with FD lists. - We have observed on the CI server that GJS 1.55.90 will hang forever while running the test suite compiled with GCC 9.0.0 and configured with the --enable-asan and --enable-ubsan arguments. This should be addressed in one of the following 1.55.x releases. - Closed bugs and merge requests: * GDBus proxy overrides should support Gio.DBusProxy.call_with_unix_fd_list() [#204, !263, Philip Chimento] * Add regression tests for GObject vfuncs [!259, Jason Hicks] * GjsPrivate: Sources should be C files [!262, Philip Chimento] * build: Vendor last-good version of AX_CODE_COVERAGE [!264, Philip Chimento] Version 1.55.4 -------------- - Closed bugs and merge requests: * Various maintenance [!258, Philip Chimento] * Boxed copy constructor should not be called, split Boxed into prototype and instance structs [#215, !260, Philip Chimento] Version 1.55.3 -------------- - Closed bugs and merge requests: * Manually constructed ByteArray toString segfaults [#219, !254, Philip Chimento] * signals: Add _signalHandlerIsConnected method [!255, Jason Hicks] * Various maintenance [!257, Philip Chimento] Version 1.52.5 -------------- - This was a release consisting only of backports from the GNOME 3.30 branch to the GNOME 3.28 branch. - This release includes the "Big Hammer" patch from GNOME 3.30 to reduce memory usage. For more information, read the blog post at It was not originally intended to be backported to GNOME 3.28, but in practice several Linux distributions already backported it, and it has been working well to reduce memory usage, and the bugs have been ironed out of it. It does decrease performance somewhat, so if you don't want that then don't install this update. - Closed bugs and merge requests: * Ensure not to miss the force_gc flag [#150, !132, Carlos Garnacho] * 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] * Reduce memory overhead of g_object_weak_ref() [#144, !122, Carlos Garnacho, Philip Chimento] * context: Defer and therefore batch forced GC runs [performance] [!236, Daniel van Vugt] * context: use timeout with seconds to schedule a gc trigger [!239, Marco Trevisan] * Use compacting GC on RSS size growth [!133, #151, Carlos Garnacho] * GType memleak fixes [!244, Marco Trevisan] Version 1.55.2 -------------- - Closed bugs and merge requests: * Gnome-shell crashes on destroying cached param specs [#213, !240, Marco Trevisan] * Various maintenance [!235, !250, Philip Chimento] * Auto pointers builder [!243, Marco Trevisan] * Update bug link [!245, Andrea Azzarone] * SIGSEGV when exiting gnome-shell [#212, !247, Andrea Azzarone, Philip Chimento] * Fix build with --enable-dtrace and create CI job to ensure it doesn't break in the future [#196, !237, !253, Philip Chimento] * Delay JSString-to-UTF8 conversion [!249, Philip Chimento] * Annotate return values [!251, Philip Chimento] * Fix a regression with GError toString() [!252, Philip Chimento] * GType memleak fixes [!244, Marco Trevisan] * Atoms refactor [!233, Philip Chimento, Marco Trevisan] * Write a "Code Hospitable" README file [#17, !248, Philip Chimento, Andy Holmes, Avi Zajac] * object: Method lookup repeatedly traverses introspection [#54, !53, Colin Walters, Philip Chimento] * Handler of GtkEditable::insert-text signal is not run [#147, !143, Tomasz Miąsko, Philip Chimento] Version 1.54.3 -------------- - Closed bugs and merge requests: * object: Fix write-only properties [!246, Philip Chimento] * SIGSEGV when exiting gnome-shell [#212, !247, Andrea Azzarone] * SelectionData.get_targets crashes with "Unable to resize vector" [#201, !241, Philip Chimento] * Gnome-shell crashes on destroying cached param specs [#213, !240, Marco Trevisan] * GType memleak fixes [!244, Marco Trevisan] * Fix build with --enable-dtrace and create CI job to ensure it doesn't break in the future [#196, !253, Philip Chimento] Version 1.54.2 -------------- - Closed bugs and merge requests: * context: Defer and therefore batch forced GC runs [performance] [!236, Daniel van Vugt] * context: use timeout with seconds to schedule a gc trigger [!239, Marco Trevisan] * fundamental: Check if gtype is valid before using it [!242, Georges Basile Stavracas Neto] - Backported a fix for a crash in the interactive interpreter when executing something like `throw "foo"` [Philip Chimento] - Backported various maintenance from 3.31 [Philip Chimento] Version 1.55.1 -------------- - New API for programs that embed GJS: gjs_memory_report(). This was already an internal API, but now it is exported. - Closed bugs and merge requests: * object: Implement newEnumerate hook for GObject [!155, Ole Jørgen Brønner] * Various maintenance [!228, Philip Chimento] * ByteArray.toString should stop at null bytes [#195, !232, Philip Chimento] * Byte arrays that represent encoded strings should be 0-terminated [#203, !232, Philip Chimento] * context: Defer and therefore batch forced GC runs [performance] [!236, Daniel van Vugt] * context: use timeout with seconds to schedule a gc trigger [!239, Marco Trevisan] * arg: Add special-case for byte arrays going to C [#67, !49, Jasper St. Pierre, Philip Chimento] Version 1.52.4 -------------- - This was a release consisting only of backports from the GNOME 3.30 branch to the GNOME 3.28 branch. - Closed bugs and merge requests: * `ARGV` encoding issues [#22, !108, Evan Welsh] * Segfault on enumeration of GjSFileImporter properties when a searchpath entry contains a symlink [#154, !144, Ole Jørgen Brønner] * Possible refcounting bug around GtkListbox signal handlers [#24, !154, Philip Chimento] * Fix up GJS_DISABLE_JIT flag now the JIT is enabled by default in SpiderMonkey [!159, Christopher Wheeldon] * Expose GObject static property symbols.

If you use the functionality, a warning will be logged asking you to upgrade your code. - Closed bugs and merge requests: * byteArray: Add compatibility toString property [Philip Chimento, !227] Version 1.53.92 --------------- - Technology preview of a GNOME 3.32 feature: native Promises for GIO-style asynchronous operations. This is the result of Avi Zajac's summer internship. To use it, you can opt in once for each specific asynchronous method, by including code such as the following: Gio._promisify(Gio.InputStream.prototype, 'read_bytes_async', 'read_bytes_finish'); After executing this, you will be able to use native Promises with the Gio.InputStream.prototype.read_async() method, simply by not passing a callback to it: try { let bytes = await stream.read_bytes_async(count, priority, cancel); } catch (e) { logError(e, 'Failed to read bytes'); } Note that any "success" boolean return values are deleted from the array of return values from the async method. That is, let [contents, etag] = file.load_contents_async(cancel); whereas the callback version still returns a useless [ok, contents, etag] that can never be false, since on false an exception would be thrown. In the callback version, we must keep this for compatibility reasons. Note that due to a bug in GJS (, promisifying methods on Gio.File.prototype and other interface prototypes will not work. We provide the API Gio._LocalFilePrototype on which you can promisify methods that will work on Gio.File instances on the local disk only: Gio._promisify(Gio._LocalFilePrototype, 'load_contents_async', 'load_contents_finish'); We estimate this will cover many common use cases. Since this is a technology preview, we do not guarantee API stability with the version coming in GNOME 3.32. These APIs are marked with underscores to emphasize that they are not stable yet. Use them at your own risk. - Closed bugs and merge requests: * Added promisify to GJS GIO overrides [!225, Avi Zajac] * Temporary fix for Gio.File.prototype [!226, Avi Zajac] Version 1.53.91 --------------- - Closed bugs and merge requests: * CI: add webkit and gtk-app tests [!222, Claudio André] * Fix example eslint errors [!207, Claudio André, Philip Chimento] * Fix more "lost" GInterface properties [!223, Florian Müllner] * Fix --enable-installed-tests when built from a tarball [!224, Simon McVittie] Version 1.53.90 --------------- - GJS now depends on SpiderMonkey 60 and requires a compiler capable of C++14. - GJS includes a simple debugger now. It has basic stepping, breaking, and printing commands, that work like GDB. Activate it by running the GJS console interpreter with the -d or --debugger flag before the name of the JS program on the command line. - New API for programs that embed GJS: gjs_context_setup_debugger_console(). To integrate the debugger into programs that embed the GJS interpreter, call this before executing the JS program. - New JavaScript features! This version of GJS is based on SpiderMonkey 60, an upgrade from the previous ESR (Extended Support Release) of SpiderMonkey 52. Here are the highlights of the new JavaScript features. For more information, look them up on MDN or * New syntax + `for await (... of ...)` syntax is used for async iteration. + The rest operator is now supported in object destructuring: e.g. `({a, b,} = {a: 1, b: 2, c: 3, d: 4});` + The spread operator is now supported in object literals: e.g. `mergedObject = {...obj1, ...obj2};` + Generator methods can now be async, using the `async function*` syntax, or `async* f() {...}` method shorthand. + It's now allowed to omit the variable binding from a catch statement, if you don't need to access the thrown exception: `try {...} catch {}` * New APIs + Promise.prototype.finally(), popular in many third-party Promise libraries, is now available natively. + String.prototype.toLocaleLowerCase() and String.prototype.toLocaleUpperCase() now take an optional locale or array of locales. + Intl.PluralRules is now available. + Intl.NumberFormat.protoype.formatToParts() is now available. + Intl.Collator now has a caseFirst option. + Intl.DateTimeFormat now has an hourCycle option. * New behaviour + There are a lot of minor behaviour changes as SpiderMonkey's JS implementation conforms ever closer to ECMAScript standards. For complete information, read the Firefox developer release notes: * Backwards-incompatible changes + Conditional catch clauses have been removed, as they were a Mozilla extension which will not be standardized. This requires some attention in GJS programs, as previously we condoned code like `catch (e if e.matches(Gio.IOError, Gio.IOError.EXISTS))` with a comment in overrides/GLib.js, so it's likely this is used in several places. + The nonstandard `for each (... in ...)` loop was removed. + The nonstandard legacy lambda syntax (`function(x) x*x`) was removed. + The nonstandard Mozilla iteration protocol was removed, as well as nonstandard Mozilla generators, including the Iterator and StopIteration objects, and the Function.prototype.isGenerator() method. + Array comprehensions and generator comprehensions have been removed. + Several nonstandard methods were removed: ArrayBuffer.slice() (but not the standard version, ArrayBuffer.prototype.slice()), Date.prototype.toLocaleFormat(), Function.prototype.isGenerator(),, and Object.prototype.unwatch(). - Many of the above backwards-incompatible changes can be caught by scanning your source code using, or - Deprecation: the custom ByteArray is now discouraged. Instead of ByteArray, use Javascript's native Uint8Array. The ByteArray module still contains functions for converting between byte arrays, strings, and GLib.Bytes instances. The old ByteArray will continue to work as before, except that Uint8Array will now be returned from introspected functions that previously returned a ByteArray. To keep your old code working, change this: let byteArray = functionThatReturnsByteArray(); to this: let byteArray = new ByteArray.ByteArray(functionThatReturnsByteArray()); To port to the new code: * ByteArray.ByteArray -> Uint8Array * ByteArray.fromArray() -> Uint8Array.from() * ByteArray.ByteArray.prototype.toString() -> ByteArray.toString() * ByteArray.ByteArray.prototype.toGBytes() -> ByteArray.toGBytes() * ByteArray.fromString(), ByteArray.fromGBytes() remain the same * Unlike ByteArray, Uint8Array's length is fixed. Assigning an element past the end of a ByteArray would lengthen the array. Now, it is ignored. Instead use Uint8Array.of(), for example, this code: let a = ByteArray.fromArray([97, 98, 99, 100]); a[4] = 101; should be replaced by this code: let a = Uint8Array.from([97, 98, 99, 100]); a = Uint8Array.of(...a, 101); The length of the byte array must be set at creation time. This code will not work anymore: let a = new ByteArray.ByteArray(); a[0] = 255; Instead, use "new Uint8Array(1)" to reserve the correct length. - Closed bugs and merge requests: * Run tests using real software [#178, !192, Claudio André] * Script tests are missing some errors [#179, !192, Claudio André] * Create a '--disable-readline' option and use it [!196, Claudio André] * CI: stop using Fedora for clang builds [!198, Claudio André] * Expose GObject static property symbols.

This should be a bit more efficient, as property info (GParamSpec) is now cached for every object type. There may still be some regressions from this; please be on the lookout so we can fix them in the next release. - The memory usage for each object instance has been reduced, resulting in several dozens of megabytes less memory usage in GNOME Shell. - The CI pipeline was refactored, now runs a lot faster, detects more failure situations, builds on different architectures, uses the GitLab Docker registry, and publishes code coverage statistics to - For contributors, the C++ style guide has been updated, and there is now a script in the tools/ directory that will install a Git hook to automatically format your code when you commit it. The configuration may not be perfect yet, so bear with us while we get it right. - Closed bugs and merge requests: * Define GObject properties and fields as JS properties [#160, !151, Philip Chimento] * Possible refcounting bug around GtkListbox signal handlers [#24, !154, Philip Chimento] * Fix up GJS_DISABLE_JIT flag now the JIT is enabled by default in SpiderMonkey [!159, Christopher Wheeldon] * Various CI maintenance [!160, !161, !162, !169, !172, !180, !191, !193, Claudio André] * Update GJS wiki URL [!157, Seth Woodworth] * Build failure in GNOME Continuous [#104, !156, Philip Chimento] * Refactor ObjectInstance into C++ class [!158, !164, Philip Chimento] * Use Ubuntu in the coverage job [!163, Claudio André] * Remove unused files [!165, Claudio André] * Add a ARMv8 build test [!166, Claudio André] * Make CI faster [!167, Claudio André] * Add a PPC4LE build test [!168, Claudio André] * gdbus: Fix deprecated API [!170, Philip Chimento] * Change Docker images names pattern [#173, !174, Claudio André] * Assert failure on a GC_ZEAL run [#165, !173, Philip Chimento] * Do not run linters on tagged commits [!181, Claudio André] * Fail on compiler warnings [!182, Claudio André] * Save code statistics in GitLab Pages [!183, Claudio André] * Build static analysis Docker image in GitLab [!184, !185, !187, !189, Claudio André] * GNOME Shell always crashes with SIGBUS [#171, !188, Georges Basile Stavracas Neto] * Coverage badge is no longer able to show its value [#177, !186, Claudio André] * Move the Docker images creation to GitLab [!190, Claudio André] * Cut the Gordian knot of coding style [#172, !171, Philip Chimento] * Some GObect/GInterface properties broke [#182, !195, Philip Chimento] Version 1.53.3 -------------- - This release was made from an earlier state of master, before a bug was introduced, while we sort out how to fix it. As a result, we don't have too many changes this round. - Closed bugs and merge requests: * Adding multiple ESLint rules for spacing [!152, Avi Zajac] * Various maintenance [!153, Philip Chimento] Version 1.53.2 -------------- - The `Template` parameter passed to `GObject.registerClass()` now accepts file:/// URIs as well as resource:/// URIs and byte arrays. - New API: `gjs_get_js_version()` returns a string identifying the version of the underlying SpiderMonkey JS engine. The interpreter executable has also gained a `--jsversion` argument which will print this string. - Several fixes for memory efficiency and performance. - Once again we welcomed contributions from a number of first-time contributors! - Closed bugs and merge requests: * Add support for file:/// uri to glade template [#108, !41, Jesus Bermudez, Philip Chimento] * Reduce memory overhead of g_object_weak_ref() [#144, !122, Carlos Garnacho, Philip Chimento] * gjs: JS_GetContextPrivate(): gjs-console killed by SIGSEGV [#148, !121, Philip Chimento] * Use compacting GC on RSS size growth [#151, !133, Carlos Garnacho] * Segfault on enumeration of GjSFileImporter properties when a searchpath entry contains a symlink [#154, !144, Ole Jørgen Brønner] * Compare linter jobs to correct base [#156, !140, Claudio André] * Various maintenance [!141, Philip Chimento] * Support interface signal handlers [!142, Tomasz Miąsko] * Remove unnecessary inline [!145, Emmanuele Bassi] * Add badges to the readme [!146, !147, Claudio André] * Fix debug logging [!148, Philip Chimento] * CI: add a GC zeal test [!149, Claudio André] Version 1.53.1 -------------- - Improvements to garbage collection performance. Read for more information: - 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] 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] 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] * 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] 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. - 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] 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] 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] 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] 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] 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] 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] 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] 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] Version 1.51.2 -------------- - Version 1.51.1 was skipped. - The home of GJS is now at GNOME's GitLab instance: 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] 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] 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 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] 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 ------- - 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, 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] 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] Version 1.48.6 -------------- - Closed bugs: * GJS crash in needsPostBarrier, possible access from wrong thread [#783935, Philip Chimento] (again) Version 1.49.4 -------------- - New JavaScript features! This version of GJS is based on SpiderMonkey 52, an upgrade from the previous ESR (Extended Support Release) of SpiderMonkey 38. GJS now uses the latest ESR in its engine and the plan is to upgrade again when SpiderMonkey 59 is released in March 2018, pending maintainer availability. Here are the highlights of the new JavaScript features. For more information, look them up on MDN or * New language features + ES6 classes + Async functions and await operator + Reflect - built-in object with methods for interceptable operations * New syntax + Exponentiation operator: `**` + Variable-length Unicode code point escapes: `"\u{1f369}"` + Destructured default arguments: `function f([x, y]=[1, 2], {z: z}={z: 3})` + Destructured rest parameters: `function f(...[a, b, c])` + `` allows a constructor access to the original constructor that was invoked + Unicode (u) flag for regular expressions, and corresponding RegExp.unicode property + Trailing comma in function parameter lists now allowed * New APIs + New Array, String, and TypedArray method: includes() + TypedArray sort(), toLocaleString(), and toString() methods, to correspond with regular arrays + New Object.getOwnPropertyDescriptors() and Object.values() methods + New Proxy traps: getPrototypeOf() and setPrototypeOf() + [Symbol.toPrimitive] property specifying how to convert an object to a primitive value + [Symbol.species] property allowing to override the default constructor for objects + [Symbol.match], [Symbol.replace], [], and [Symbol.split] properties allowing to customize matching behaviour in RegExp subclasses + [Symbol.hasInstance] property allowing to customize the behaviour of the instanceof operator for objects + [Symbol.toStringTag] property allowing to customize the message printed by Object.toString() without overriding it + [Symbol.isConcatSpreadable] property allowing to control the behaviour of an array subclass in an argument list to Array.concat() + [Symbol.unscopables] property allowing to control which object properties are lifted into the scope of a with statement + New Intl.getCanonicalLocales() method + Date.toString() and RegExp.toString() generic methods + Typed arrays can now be constructed from any iterable object + Array.toLocaleString() gained optional locales and options arguments, to correspond with other toLocaleString() methods * New behaviour + The "arguments" object is now iterable + Date.prototype, WeakMap.prototype, and WeakSet.prototype are now ordinary objects, not instances + Full ES6-compliant implementation of let keyword + RegExp.sticky ('y' flag) behaviour is ES6 standard, it used to be subject to a long-standing bug in Firefox + RegExp constructor with RegExp first argument and flags no longer throws an exception (`new RegExp(/ab+c/, 'i')` works now) + Generators are no longer constructible, as per ES6 (`function* f {}` followed by `new f` will not work) + It is now required to construct ArrayBuffer, TypedArray, Map, Set, and WeakMap with the new operator + Block-level functions (e.g. `{ function foo() {} }`) are now allowed in strict mode; they are scoped to their block + The options.timeZone argument to Date.toLocaleDateString(), Date.toLocaleString(), Date.toLocaleTimeString(), and the constructor of Intl.DateTimeFormat now understands IANA time zone names (such as "America/Vancouver") * Backwards-incompatible changes + Non-standard "let expressions" and "let blocks" (e.g., `let (x = 5) { use(x) }`) are not supported any longer + Non-standard flags argument to String.match(), String.replace(), and (e.g. `str.replace('foo', 'bar', 'g')`) is now ignored + Non-standard WeakSet.clear() method has been removed + Variables declared with let and const are now 'global lexical bindings', as per the ES6 standard, meaning that they will not be exported in modules. We are maintaining the old behaviour for the time being as a compatibility workaround, but please change "let" or "const" to "var" inside your module file. A warning will remind you of this. For more information, read: * Experimental features (may change in future versions) + String.padEnd(), String.padStart() methods (proposed in ES2017) + Intl.DateTimeFormat.formatToParts() method (proposed in ES2017) + Object.entries() method (proposed in ES2017) + Atomics, SharedArrayBuffer, and WebAssembly are disabled by default, but can be enabled if you compile mozjs yourself - Closed bugs: * Prepare for SpiderMonkey 45 and 52 [#781429, Philip Chimento] * Add a static analysis tool as a make target [#783214, Claudio André] * Fix the build with debug logs enabled [#784469, Tomas Popela] * Switch to SpiderMonkey 52 [#784196, Philip Chimento, Chun-wei Fan] * Test suite fails when run with JIT enabled [#616193, Philip Chimento] Version 1.48.5 -------------- - Closed bugs: * GJS crash in needsPostBarrier, possible access from wrong thread [#783935, Philip Chimento] - Fix format string, caught by static analysis [Claudio André] - Fixes for regression in 1.48.4 [Philip Chimento] Version 1.49.3 -------------- - This will be the last release using SpiderMonkey 38. - Fixes in preparation for SpiderMonkey 52 [Philip Chimento] - Use the Centricular fork of libffi to build on Windows [Chun-wei Fan] - Closed bugs: * [RFC] Use a C++ auto pointer instead of g_autofree [#777597, Chun-wei Fan, Daniel Boles, Philip Chimento] * Build failure in GNOME Continuous [#783031, Chun-wei Fan] Version 1.48.4 -------------- - Closed bugs: * gnome-shell 3.24.1 crash on wayland [#781799, Philip Chimento]; thanks to everyone who contributed clues Version 1.49.2 -------------- - New feature: When building an app with the Package module, using the Meson build system, you can now run the app with "ninja run" and all the paths will be set up correctly. - New feature: Gio.ListStore is now iterable. - New API: Package.requireSymbol(), a companion for the already existing Package.require(), that not only checks for a GIR library but also for a symbol defined in that library. - New API: Package.checkSymbol(), similar to Package.requireSymbol() but does not exit if the symbol was not found. Use this to support older versions of a GIR library with fallback functionality. - New API: System.dumpHeap(), for debugging only. Prints the state of the JS engine's heap to standard output. Takes an optional filename parameter which will dump to a file instead if given. - Closed bugs: * Make gjs build on Windows/Visual Studio [#775868, Chun-wei Fan] * Bring back fancy error reporter in gjs-console [#781882, Philip Chimento] * Add Meson running from source support to package.js [#781882, Patrick Griffis] * package: Fix initSubmodule() when running from source in Meson [#782065, Patrick Griffis] * package: Set GSETTINGS_SCHEMA_DIR when ran from source [#782069, Patrick Griffis] * Add to check for symbol availability [#779593, Florian Müllner] * overrides: Implement Gio.ListStore[Symbol.iterator] [#782310, Patrick Griffis] * tweener: Explicitly check for undefined properties [#781219, Debarshi Ray, Philip Chimento] * Add a way to dump the heap [#780106, Juan Pablo Ugarte] - Fixes in preparation for SpiderMonkey 52 [Philip Chimento] - Misc fixes [Philip Chimento] Version 1.48.3 -------------- - Closed bugs: * arg: don't crash when asked to convert a null strv to an array [#775679, Cosimo Cecchi, Sam Spilsbury] * gjs 1.48.0: does not compile on macOS with clang [#780350, Tom Schoonjans, Philip Chimento] * Modernize shell scripts [#781806, Claudio André] Version 1.49.1 -------------- - Closed bugs: * test GObject Class failure [#693676, Stef Walter] * Enable incremental GCs [#724797, Giovanni Campagna] * Don't silently accept extra arguments to C functions [#680215, Jasper St. Pierre, Philip Chimento] * Special case GValues in signals and properties [#688128, Giovanni Campagna, Philip Chimento] * [cairo] Instantiate wrappers properly [#614413, Philip Chimento, Johan Dahlin] * Warn if we're importing an unversioned namespace [#689654, Colin Walters, Philip Chimento] - Fixes in preparation for SpiderMonkey 45 [Philip Chimento] - Misc fixes [Philip Chimento, Chun-wei Fan, Dan Winship] Version 1.48.2 -------------- - Closed bugs: * Intermittent crash in gnome-shell, probably in weak pointer updating code [#781194, Georges Basile Stavracas Neto] * Add contributor's guide [#781297, Philip Chimento] - Misc fixes [Debarshi Ray, Philip Chimento] Version 1.48.1 -------------- - Closed bugs: * gjs crashed with SIGSEGV in gjs_object_from_g_object [#779918, Philip Chimento] - Misc bug fixes [Florian Müllner, Philip Chimento, Emmanuele Bassi] Version 1.48.0 -------------- - Closed bugs: * Memory leak in object_instance_resolve() [#780171, Philip Chimento]; thanks to Luke Jones and Hussam Al-Tayeb Version 1.47.92 --------------- - Closed bugs: * gjs 1.47.91 configure fails with Fedora's mozjs38 [#779412, Philip Chimento] * tests: Don't fail when Gtk+-4.0 is available [#779594, Florian Müllner] * gjs 1.47.91 test failures on non-amd64 [#779399, Philip Chimento] * gjs_eval_thread should always be set [#779693, Philip Chimento] * System.exit() should exit even across main loop iterations [#779692, Philip Chimento] * Fix a typo in [#779772, Claudio André] * arg: Fix accidental fallthrough [#779838, Florian Müllner] * jsUnit: Explicitly check if tempTop.parent is defined [#779871, Iain Lane] - Misc bug fixes [Philip Chimento] Version 1.47.91 --------------- - Closed bugs: * overrides/Gio: Provide an empty array on error, rather than null [#677513, Jasper St. Pierre, Philip Chimento] * WithSignals parameter for Lang.Class [#664897, Philip Chimento] * add API to better support asynchronous code [#608450, Philip Chimento] * 1.47.90 tests are failing [#778780, Philip Chimento] * boxed: Plug a memory leak [#779036, Florian Müllner] * Don't crash when marshalling an unsafe integer from introspection [#778705, Philip Chimento] * Lang.Class should include symbol properties [#778718, Philip Chimento] * Console output of arrays should be UTF-8 aware [#778729, Philip Chimento] * Various fixes for 1.47.91 [#779293, Philip Chimento] - Progress towards a Visual Studio build of GJS on Windows [Chun-wei Fan] - Misc bug fixes [Chun-wei Fan, Philip Chimento] Version 1.47.90 --------------- - New JavaScript features! This version of GJS is based on SpiderMonkey 38, an upgrade from the previous ESR (Extended Support Release) of SpiderMonkey 31. Our plans are to continue upgrading to subsequent ESRs as maintainer availability allows. Here are the highlights of the new JavaScript features. For more information, look them up on MDN or * New syntax + Shorthand syntax for method definitions: { foo() { return 5; } } + Shorthand syntax for object literals: let b = 42; let o = {b}; o.b === 42 + Computed property names for the above, as well as in getter and setter expressions and destructuring assignment: { ['b' + 'ar']() { return 6; } } + Spread operator in destructuring assignment: let [a, ...b] = [1, 2, 3]; + Template literals: `Hello, ${name}` with optional tags: tag`string` * New APIs + Symbol, a new fundamental type + WeakSet, a Set which does not prevent its members from being garbage-collected + [Symbol.iterator] properties for Array, Map, Set, String, TypedArray, and the arguments object + New Array and TypedArray functionality: Array.copyWithin(), Array.from() + New return() method for generators + New Number.isSafeInteger() method + New Object.assign() method which can replace Lang.copyProperties() in many cases + New Object.getOwnPropertySymbols() method + New RegExp flags, global, ignoreCase, multiline, sticky properties that give access to the flags that the regular expression was created with + String.raw, a tag for template strings similar to Python's r"" + New TypedArray methods for correspondence with Array: entries(), every(), fill(), filter(), find(), findIndex(), forEach(), indexOf(), join(), keys(), lastIndexOf(), map(), of(), reduce(), reduceRight(), reverse(), slice(), some(), values() * New behaviour + Temporal dead zone: print(x); let x = 5; no longer allowed + Full ES6-compliant implementation of const keyword + The Set, Map, and WeakMap constructors can now take null as their argument + The WeakMap constructor can now take an iterable as its argument + The and Function.length properties are configurable + When subclassing Map, WeakMap, and Set or using the constructors on generic objects, they will look for custom set() and add() methods. + RegExp.source and RegExp.toString() now deal with empty regexes, and escape their output. + Non-object arguments to Object.preventExtensions() now do not throw an exception, simply return the original object * Backwards-incompatible changes + It is now a syntax error to declare the same variable twice with "let" or "const" in the same scope. Existing code may need to be fixed, but the fix is trivial. + SpiderMonkey is now extra vocal about warning when you access an undefined property, and this causes some false positives. You can turn this warning off by setting GJS_DISABLE_EXTRA_WARNINGS=1. If it is overly annoying, let me know and I will consider making it disabled by default in a future release. + When enumerating the importer object (i.e., "for (let i in imports) {...}") you will now get the names of any built-in modules that have previously been imported. (But don't do this, anyway.) - Closed bugs: * SpiderMonkey 38 prep [#776966, Philip Chimento] * Misc fixes [#777205, Philip Chimento] * missing class name in error message [#642506, Philip Chimento] * Add continuous integration to GJS [#776549, Claudio André] * Switch to SpiderMonkey 38 [#777962, Philip Chimento] - Progress towards a build of GJS on Windows [Chun-wei Fan] - Progress towards increasing test coverage [Claudio André] - Misc bug fixes [Philip Chimento] Version 1.47.4 -------------- - New JavaScript feature: ES6 Promises. This release includes Lie [1], a small, self-contained Promise implementation, which is imported automatically to form the Promise global object [2]. In the future, Promises will be built into the SpiderMonkey engine and Lie will be removed, but any code using Promises will continue to work as before. [1] [2] - News for GJS embedders such as gnome-shell: * New API: The GjsCoverage type and its methods are now exposed. Use this if you are embedding GJS and need to output code coverage statistics. - Closed bugs: * Add GjsCoverage to gjs-1.0 public API [#775776, Philip Chimento] * Should use uint32_t instead of u_int32_t in coverage.cpp [#776193, Shawn Walker, Alan Coopersmith] * Port tests to use an embedded copy of Jasmine [#775444, Philip Chimento] * support fields in GObject [#563391, Havoc Pennington, Philip Chimento] * Javascript errors in property getters and setter not always reported [#730101, Matt Watson, Philip Chimento] * Exception swallowed while importing Gom [#737607, Philip Chimento] * log a warning if addSignalMethods() replaces existing methods [#619710, Joe Shaw, Philip Chimento] * Provide a useful toString for importer and module objects [#636283, Jasper St. Pierre, Philip Chimento] * Fails to marshal out arrays [#697020, Paolo Borelli] * coverage: Don't warn about executing odd lines by default anymore [#751146, Sam Spilsbury, Philip Chimento] * coverage: Crash in EnterBaseline on SpiderMonkey when Ion is enabled during coverage mode. [#742852, Sam Spilsbury, Philip Chimento] * installed tests cannot load [#776938, Philip Chimento] * Crash with subclassed fundamental with no introspection [#760057, Lionel Landwerlin] - Misc bug fixes [Philip Chimento, Claudio André] Version 1.47.3 -------------- - New JavaScript features! This version of GJS is based on SpiderMonkey 31, an upgrade from the previous ESR (Extended Support Release) of SpiderMonkey 24. Our plans are to continue upgrading to subsequent ESRs as maintainer availability allows. Here are the highlights of the new JavaScript features. For more information, look them up on MDN or * New syntax + Spread operator in function calls: someFunction(arg1, arg2, ...iterableObj) + Generator functions: yield, function*, yield* + Binary and octal numeric literals: 0b10011100, 0o377 + Function arguments without defaults can now come after those with defaults: function f(x=1, y) {} * New standard library module + Intl - Locale-sensitive formatting and string comparison * New APIs + Iterator protocol - any object implementing certain methods is an "iterator" + New Array functionality: fill(), find(), findIndex(), of() + New String functionality for working with Unicode: codePointAt(), fromCodePoint(), normalize() + New Array methods for correspondence with Object: entries(), keys() + ES6 Generator methods to replace the old Firefox-specific generator API: next(), throw() + forEach() methods for Map and Set, for correspondence with Array + A bunch of new Math functions: acosh(), asinh(), atanh(), cbrt(), clz32(), cosh(), expm1(), fround(), hypot(), log10(), log1p(), log2(), sign(), sinh(), tanh(), trunc() + Some constants to tell information about float support on the platform: Number.EPSILON, Number.MAX_SAFE_INTEGER, Number.MIN_SAFE_INTEGER + New Number.parseInt() and Number.parseFloat() which are now preferred over those in the global namespace + New Object.setPrototypeOf() which now is preferred over setting obj.prototype.__proto__ + New locales and options extra arguments to all toLocaleString() and related methods + Misc new functionality: ArrayBuffer.isView(), Proxy.handler.isExtensible, Proxy.revocable() * New behaviour + -0 and +0 are now considered equal as Map keys and Set values + On typed arrays, numerical indexed properties ignore the prototype object: Int8Array.prototype[20] = 'foo'; (new Int8Array(32))[20] == 0 * New non-standard Mozilla extensions + Array comprehensions + Generator comprehensions; both were originally proposed for ES6 but removed - Backwards-incompatible change: we have changed the way certain JavaScript values are marshalled into GObject introspection 32 or 64-bit signed integer values, to match the ECMA standard. Here is the relevant section of the standard: Notable differences between the old and new behaviour are: * Floating-point numbers ending in 0.5 are rounded differently when marshalled into 32 or 64-bit signed integers. Previously they were rounded to floor(x + 0.5), now they are rounded to signum(x) * floor(abs(x)) as per the ECMA standard: Note that previously, GJS rounded according to the standard when converting to *unsigned* integers! * Objects whose number value is NaN (e.g, arrays of strings), would previously fail to convert, throwing a TypeError. Now they convert to 0 when marshalled into 32 or 64-bit signed integers. Note that the new behaviour is the behaviour you got all along when using pure JavaScript, without any GObject introspection: gjs> let a = new Int32Array(2); gjs> a[0] = 10.5; 10.5 gjs> a[1] = ['this', 'is', 'fine']; this,is,fine gjs> a[0] 10 gjs> a[1] 0 - News for GJS embedders such as gnome-shell: * New API: gjs_error_quark() is now exposed, and the error domain GJS_ERROR and codes GJS_ERROR_FAILED and GJS_ERROR_SYSTEM_EXIT. * Backwards-incompatible change: Calling System.exit() from JS code will now not abort the program immediately, but instead will return immediately from gjs_context_eval() so that you can unref your GjsContext before internal resources are released on exit. If gjs_context_eval() or gjs_context_eval_file() returns an error with code GJS_ERROR_SYSTEM_EXIT, it means that the JS code called System.exit(). The exit code will be found in the 'exit_status_p' out parameter to gjs_context_eval() or gjs_context_eval_file(). If you receive this error, you should do any cleanup needed and exit your program with the given exit code. - Closed bugs: * spidermonkey 31 prep [Philip Chimento, Tim Lunn, #742249] * Please use dbus-run-session to run dbus related tests [Philip Chimento, #771745] * don't abort gdb'd tests [Philip Chimento, Havoc Pennington, #605972] * Use Automake test suite runner [Philip Chimento, #775205] * please add doc/ directory to make dist tar file [Philip Chimento, #595439] * support new mozjs 31.5 [Philip Chimento, #751252] * SEGFAULT in js::NewObjectWithClassProtoCommon when instantiating a dynamic type defined in JS [Philip Chimento, Juan Pablo Ugarte, #770244] - Misc bug fixes [Philip Chimento, Alexander Larsson] Version 1.47.0 -------------- - New API: GLib.log_structured() is a convenience wrapper for the C function g_log_variant(), allowing you to do structured logging without creating GVariants by hand. For example: GLib.log_structured('test', GLib.LogLevelFlags.LEVEL_WARNING, { 'MESSAGE': 'Just a test', 'A_FIELD': 'A value', }); - Backwards-incompatible change: we have changed the way gjs-console interprets command-line arguments. Previously there was a heuristic to try to decide whether "--help" given on the command line was meant for GJS itself or for a script being launched. This did not work in some cases, for example: $ gjs -c 'if (ARGV.indexOf("--help") == -1) throw "ugh"' --help would print the GJS help. Now, all arguments meant for GJS itself must come _before_ the name of the script to execute or any script given with a "-c" argument. Any arguments _after_ the filename or script are passed on to the script. This is the way that Python handles its command line arguments as well. If you previously relied on any -I arguments after your script being added to the search path, then you should either reorder those arguments, use GJS_PATH, or handle -I inside your script, adding paths to imports.searchPath manually. In order to ease the pain of migration, GJS will continue to take those arguments into account for the time being, while still passing them on to the script. A warning will be logged if you are using the deprecated behaviour. - News for GJS embedders such as gnome-shell: * Removed API: The gjs-internals-1.0 API is now discontinued. Since gnome-shell was the only known user of this API, its pkg-config file has been removed completely and gnome-shell has been patched not to use it. - Closed bugs: * make check fails with --enable-debug / -DDEBUG spidermonkey [Philip Chimento, #573335] * Modernize autotools configuration [Philip Chimento, #772027] * overrides/GLib: Add log_structured() -
