+Name: Chromium base:: helper Classes
+Short Name: base::numerics, base::MRUCachem, base::SHA1
+Version:
+URL: https://chromium.googlesource.com/chromium/src/base/+/master
+SOURCE CODE: Copy the Chromium folder manually into this folder and run git cl format.
+Date: 24/05/2017
+Revision: 28b5bbb227d331c01e6ff9b2f8729732135aadc7 (Chromium)
+Security Critical: no
+License: Chromium
+License File: LICENSE in Chromium/src
+
+Description:
+base::numerics is a library for doing some simple safe math and conversions.
+base::MRUCache is a few collections of most-recently-used caching structures.
+base::SHA1 is a secure hashing algorithm.
+
+To update the checkout, simply overwrite the folder with Chromium's latest, apply
+the appropriate namespace, and make sure the paths are correct (anglebase/ instead of
+base/), and update the header guards and macros.
+
+Modifications:
+
+- the file scope is now anglebase/ from base/ to prevent include conflicts.
+- anglebase/logging.h defines (D)CHECK to be ASSERT to be compatible with ANGLE.
+- the headers use namespace angle::base instead of base:: to avoid ODR
+  violations when ANGLE code is mixed with Chromium code.
+- header guards and macros are changed from BASE to ANGLEBASE to prevent conflicts.

+// The following helper template addresses a corner case in range checks for

+//      truncated to fit the mantissa of the floating point. The direction of
+//      rounding is implementation defined, but by default it's always IEEE
+//      floats, which round to nearest and thus result in a value of larger
+//      magnitude than the integral value.
+//      Example: float f = UINT_MAX; // f is 4294967296f but UINT_MAX
+//                                   // is 4294967295u.
+//   2. If the floating point value is equal to the promoted integral maximum
+//      value, a range check will erroneously pass.
+//      Example: (4294967296f <= 4294967295u) // This is true due to a precision
+//                                            // loss in rounding up to float.
+//   3. When the floating point value is then converted to an integral, the
+//      resulting value is out of range for the target integral type and
+//      thus is implementation defined.
+//      Example: unsigned u = (float)INT_MAX; // u will typically overflow to 0.
+// To fix this bug we manually truncate the maximum value when the destination
+// type is an integral of larger precision than the source floating-point type,
+// such that the resulting maximum is represented exactly as a floating point.

+ * This implementation was written by Shane Day, and is also public domain.

+
+/*-----------------------------------------------------------------------------
+ 
+If you want to understand the MurmurHash algorithm you would be much better
+off reading the original source. Just point your browser at:
+http://code.google.com/p/smhasher/source/browse/trunk/MurmurHash3.cpp
+
+
+What this version provides?
+
+1. Progressive data feeding. Useful when the entire payload to be hashed
+does not fit in memory or when the data is streamed through the application.
+Also useful when hashing a number of strings with a common prefix. A partial
+hash of a prefix string can be generated and reused for each suffix string.
+
+2. Portability. Plain old C so that it should compile on any old compiler.
+Both CPU endian and access-alignment neutral, but avoiding inefficient code
+when possible depending on CPU capabilities.
+
+3. Drop in. I personally like nice self contained public domain code, making it
+easy to pilfer without loads of refactoring to work properly in the existing
+application code & makefile structure and mucking around with licence files.
+Just copy PMurHash.h and PMurHash.c and you're ready to go.
+
+
+How does it work?
+
+We can only process entire 32 bit chunks of input, except for the very end
+that may be shorter. So along with the partial hash we need to give back to
+the caller a carry containing up to 3 bytes that we were unable to process.
+This carry also needs to record the number of bytes the carry holds. I use
+the low 2 bits as a count (0..3) and the carry bytes are shifted into the
+high byte in stream order.
+
+To handle endianess I simply use a macro that reads a uint32_t and define
+that macro to be a direct read on little endian machines, a read and swap
+on big endian machines, or a byte-by-byte read if the endianess is unknown.

+//     that comes from a series of assignments, possibly with swizzled or ternary operators with
+//     known conditionals, where the source is before the loop.
+//     So, a workaround is to add a +0 term to variables the first time they are assigned to in
+//     an inner loop (if they are declared in an outside scope, otherwise there is no need).
+//     This will break the aliasing chain.
+
+// For simplicity here we add a +0 to any assignment that is in at least two nested loops. Because

+ *
+ * - query NV_CTRL_GVO_SUPPORTED to determine if the X screen supports GV0.
+ *
+ * - specify NV_CTRL_GVO_SYNC_MODE (one of FREE_RUNNING, GENLOCK, or
+ * FRAMELOCK); if you specify GENLOCK or FRAMELOCK, you should also
+ * specify NV_CTRL_GVO_SYNC_SOURCE.
+ *
+ * - Use NV_CTRL_GVO_COMPOSITE_SYNC_INPUT_DETECTED and
+ * NV_CTRL_GVO_SDI_SYNC_INPUT_DETECTED to detect what input syncs are
+ * present.
+ *
+ * (If no analog sync is detected but it is known that a valid
+ * bi-level or tri-level sync is connected set
+ * NV_CTRL_GVO_COMPOSITE_SYNC_INPUT_DETECT_MODE appropriately and
+ * retest with NV_CTRL_GVO_COMPOSITE_SYNC_INPUT_DETECTED).
+ *
+ * - if syncing to input sync, query the
+ * NV_CTRL_GVIO_DETECTED_VIDEO_FORMAT attribute; note that Input video
+ * format can only be queried after SYNC_SOURCE is specified.
+ *
+ * - specify the NV_CTRL_GVIO_REQUESTED_VIDEO_FORMAT
+ *
+ * - specify the NV_CTRL_GVO_DATA_FORMAT
+ *
+ * - specify any custom Color Space Conversion (CSC) matrix, offset,
+ * and scale with XNVCTRLSetGvoColorConversion().
+ *
+ * - if using the GLX_NV_video_out extension to display one or more
+ * pbuffers, call glXGetVideoDeviceNV() to lock the GVO output for use
+ * by the GLX client; then bind the pbuffer(s) to the GVO output with
+ * glXBindVideoImageNV() and send pbuffers to the GVO output with
+ * glXSendPbufferToVideoNV(); see the GLX_NV_video_out spec for more
+ * details.
+ *
+ * - if using the GLX_NV_present_video extension, call
+ * glXBindVideoDeviceNV() to bind the GVO video device to current
+ * OpenGL context.
+ *
+ * Note that setting most GVO attributes only causes the value to be
+ * cached in the X server.  The values will be flushed to the hardware
+ * either when the next MetaMode is set that uses the GVO display
+ * device, or when a GLX pbuffer is bound to the GVO output (with
+ * glXBindVideoImageNV()).
+ *
+ * Note that GLX_NV_video_out/GLX_NV_present_video and X screen use
+ * are mutually exclusive.  If a MetaMode is currently using the GVO
+ * device, then glXGetVideoDeviceNV and glXBindVideoImageNV() will
+ * fail.  Similarly, if a GLX client has locked the GVO output (via
+ * glXGetVideoDeviceNV or glXBindVideoImageNV), then setting a

+ *
+ * NV-CONTROL Protocol Version History
+ *
+ * 1.0 - 1.5   NVIDIA Internal development versions
+ * 1.6         Initial public version
+ * 1.7         Added QueryBinaryData request
+ * 1.8         Added TargetTypes
+ * 1.9         Added QueryTargetCount request
+ * 1.10        Fixed target type/id byte ordering for compatibility with
+ *             pre-1.8 NV-CONTROL clients
+ * 1.11        NVIDIA Internal development version
+ * 1.12        Added StringOperation request
+ * 1.13        NVIDIA Internal development version
+ * 1.14        Fixed an NV_CTRL_BINARY_DATA_MODELINES double scan modeline
+ *             reporting bug (vsyncstart, vsyncend, and vtotal were incorrectly
+ *             doubled)
+ * 1.15        Added AVAILABILITY_TARGET_ATTRIBUTE_CHANGED_EVENT
+ * 1.16        Added TARGET_STRING_ATTRIBUTE_CHANGED_EVENT
+ * 1.17        Added TARGET_BINARY_ATTRIBUTE_CHANGED_EVENT
+ * 1.18        Updated QueryTargetCount to return a count of 0, rather than
+ *             BadMatch, if an unknown TargetType is specified
+ * 1.19        Added TargetType support for SetAttributeAndGetStatus and
+ *             SetStringAttribute requests
+ * 1.20        Added COOLER TargetType
+ * 1.21        Added initial 64-bit integer attribute support (read-only)
+ * 1.22        Added X_nvCtrlQueryValidStringAttributeValues to check
+ *             string attribute permissions.
+ * 1.23        Added SENSOR TargetType
+ * 1.24        Fixed a bug where SLI_MOSAIC_MODE_AVAILABLE attribute would
+ *             report false positives via the GPU and X screen target types
+ * 1.25        Added 3D_VISION_PRO_TRANSCEIVER TargetType
+ * 1.26        Added XNVCTRLQueryXXXAttributePermissions.
+ * 1.27        Added DISPLAY TargetType
+ * 1.28        Added NV_CTRL_CURRENT_METAMODE_ID: clients should use this
+ *             attribute to switch MetaModes, rather than pass the MetaMode ID
+ *             through the RRSetScreenConfig protocol request.

+** with CONSTANT within the WHERE clause.
+**
+** For example, the query:
+**
+**      SELECT * FROM t1, t2, t3 WHERE t1.a=39 AND t2.b=t1.a AND t3.c=t2.b

+** Implementation note:  Constant propagation is tricky due to affinity

+**
+**    CREATE TABLE t1(a INT,b TEXT);
+**    INSERT INTO t1 VALUES(123,'0123');

+** is false because it uses text affinity and '0123' is not the same as '123'.
+** To work around this, the expression tree is not actually changed from
+** "b=a" to "b=123" but rather the "a" in "b=a" is tagged with EP_FixedCol
+** and the "123" value is hung off of the pLeft pointer.  Code generator
+** routines know to generate the constant "123" instead of looking up the

+/*
+** SELECT REWRITING
+**
+**   Any SELECT statement that contains one or more window functions in
+**   either the select list or ORDER BY clause (the only two places window
+**   functions may be used) is transformed by function sqlite3WindowRewrite()
+**   in order to support window function processing. For example, with the
+**   schema:
+**
+**     CREATE TABLE t1(a, b, c, d, e, f, g);
+**
+**   the statement:
+**
+**     SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM t1 ORDER BY e;
+**
+**   is transformed to:
+**
+**     SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM (
+**         SELECT a, e, c, d, b FROM t1 ORDER BY c, d
+**     ) ORDER BY e;
+**
+**   The flattening optimization is disabled when processing this transformed
+**   SELECT statement. This allows the implementation of the window function
+**   (in this case max()) to process rows sorted in order of (c, d), which
+**   makes things easier for obvious reasons. More generally:
+**
+**     * FROM, WHERE, GROUP BY and HAVING clauses are all moved to 
+**       the sub-query.
+**
+**     * ORDER BY, LIMIT and OFFSET remain part of the parent query.
+**
+**     * Terminals from each of the expression trees that make up the 
+**       select-list and ORDER BY expressions in the parent query are
+**       selected by the sub-query. For the purposes of the transformation,
+**       terminals are column references and aggregate functions.
+**
+**   If there is more than one window function in the SELECT that uses
+**   the same window declaration (the OVER bit), then a single scan may
+**   be used to process more than one window function. For example:
+**
+**     SELECT max(b) OVER (PARTITION BY c ORDER BY d), 
+**            min(e) OVER (PARTITION BY c ORDER BY d) 
+**     FROM t1;
+**
+**   is transformed in the same way as the example above. However:
+**
+**     SELECT max(b) OVER (PARTITION BY c ORDER BY d), 
+**            min(e) OVER (PARTITION BY a ORDER BY b) 
+**     FROM t1;
+**
+**   Must be transformed to:
+**
+**     SELECT max(b) OVER (PARTITION BY c ORDER BY d) FROM (
+**         SELECT e, min(e) OVER (PARTITION BY a ORDER BY b), c, d, b FROM
+**           SELECT a, e, c, d, b FROM t1 ORDER BY a, b
+**         ) ORDER BY c, d
+**     ) ORDER BY e;
+**
+**   so that both min() and max() may process rows in the order defined by
+**   their respective window declarations.
+**
+** INTERFACE WITH SELECT.C
+**
+**   When processing the rewritten SELECT statement, code in select.c calls
+**   sqlite3WhereBegin() to begin iterating through the results of the
+**   sub-query, which is always implemented as a co-routine. It then calls
+**   sqlite3WindowCodeStep() to process rows and finish the scan by calling
+**   sqlite3WhereEnd().
+**
+**   sqlite3WindowCodeStep() generates VM code so that, for each row returned
+**   by the sub-query a sub-routine (OP_Gosub) coded by select.c is invoked.
+**   When the sub-routine is invoked:
+**
+**     * The results of all window-functions for the row are stored
+**       in the associated Window.regResult registers.
+**
+**     * The required terminal values are stored in the current row of
+**       temp table Window.iEphCsr.
+**
+**   In some cases, depending on the window frame and the specific window
+**   functions invoked, sqlite3WindowCodeStep() caches each entire partition
+**   in a temp table before returning any rows. In other cases it does not.
+**   This detail is encapsulated within this file, the code generated by
+**   select.c is the same in either case.
+**
+** BUILT-IN WINDOW FUNCTIONS
+**
+**   This implementation features the following built-in window functions:
+**
+**     row_number()
+**     rank()
+**     dense_rank()
+**     percent_rank()
+**     cume_dist()
+**     ntile(N)
+**     lead(expr [, offset [, default]])
+**     lag(expr [, offset [, default]])
+**     first_value(expr)
+**     last_value(expr)
+**     nth_value(expr, N)
+**   
+**   These are the same built-in window functions supported by Postgres. 
+**   Although the behaviour of aggregate window functions (functions that
+**   can be used as either aggregates or window funtions) allows them to
+**   be implemented using an API, built-in window functions are much more
+**   esoteric. Additionally, some window functions (e.g. nth_value()) 
+**   may only be implemented by caching the entire partition in memory.
+**   As such, some built-in window functions use the same API as aggregate
+**   window functions and some are implemented directly using VDBE 
+**   instructions. Additionally, for those functions that use the API, the
+**   window frame is sometimes modified before the SELECT statement is
+**   rewritten. For example, regardless of the specified window frame, the
+**   row_number() function always uses:
+**
+**     ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
+**
+**   See sqlite3WindowUpdate() for details.
+**
+**   As well as some of the built-in window functions, aggregate window
+**   functions min() and max() are implemented using VDBE instructions if
+**   the start of the window frame is declared as anything other than 
+**   UNBOUNDED PRECEDING.

-libxkbcommon 0.4.1
+libxkbcommon 0.8.2 - 2018-08-05
+==================
+
+- Fix various problems found with fuzzing (see commit messages for
+  more details):
+
+    - Fix a few NULL-dereferences, out-of-bounds access and undefined behavior
+      in the XKB text format parser.
+
+
+libxkbcommon 0.8.1 - 2018-08-03
+==================
+
+- Fix various problems found in the meson build (see commit messages for more
+  details):
+
+    - Fix compilation on Darwin.
+
+    - Fix compilation of the x11 tests and demos when XCB is installed in a
+      non-standard location.
+
+    - Fix xkbcommon-x11.pc missing the Requires specification.
+
+- Fix various problems found with fuzzing and Coverity (see commit messages for
+  more details):
+
+    - Fix stack overflow in the XKB text format parser when evaluating boolean
+      negation.
+
+    - Fix NULL-dereferences in the XKB text format parser when some unsupported
+      tokens appear (the tokens are still parsed for backward compatibility).
+
+    - Fix NULL-dereference in the XKB text format parser when parsing an
+      xkb_geometry section.
+
+    - Fix an infinite loop in the Compose text format parser on some inputs.
+
+    - Fix an invalid free() when using multiple keysyms.
+
+- Replace the Unicode characters for the leftanglebracket and rightanglebracket
+  keysyms from the deprecated LEFT/RIGHT-POINTING ANGLE BRACKET to
+  MATHEMATICAL LEFT/RIGHT ANGLE BRACKET.
+
+- Reject out-of-range Unicode codepoints in xkb_keysym_to_utf8 and
+  xkb_keysym_to_utf32.
+
+
+libxkbcommon 0.8.0 - 2017-12-15
+==================
+
+- Added xkb_keysym_to_{upper,lower} to perform case-conversion directly on
+  keysyms. This is useful in some odd cases, but working with the Unicode
+  representations should be preferred when possible.
+
+- Added Unicode conversion rules for the signifblank and permille keysyms.
+
+- Fixed a bug in the parsing of XKB key type definitions where the number
+  of levels were determined by the number of level *names*. Keymaps which
+  omit level names were hence miscompiled.
+
+  This regressed in version 0.4.3. Keymaps from xkeyboard-config were not
+  affected since they don't omit level names.
+
+- New API:
+  xkb_keysym_to_upper()
+  xkb_keysym_to_lower()
+
+
+libxkbcommon 0.7.2 - 2017-08-04
+==================
+
+- Added a Meson build system as an alternative to existing autotools build
+  system.
+
+  The intent is to remove the autotools build in one of the next releases.
+  Please try to convert to it and report any problems.
+
+  See http://mesonbuild.com/Quick-guide.html for basic usage, the
+  meson_options.txt for the project-specific configuration options,
+  and the PACKAGING file for more details.
+
+  There are some noteworthy differences compared to the autotools build:
+
+  - Feature auto-detection is not performed. By default, all features are
+    enabled (currently: docs, x11, wayland). The build fails if any of
+    the required dependencies are not available. To disable a feature,
+    pass -Denable-<feature>=false to meson.
+
+  - The libraries are either installed as shared or static, as specified
+    by the -Ddefault_library=shared/static option. With autotools, both
+    versions are installed by default.
+
+  - xorg-util-macros is not used.
+
+  - A parser generator (bison/byacc) is always required - there is no
+    fallback to pre-generated output bundled in the tarball, as there is
+    in autotools.
+
+- Removed Android.mk support.
+
+- Removed the *-uninstalled.pc pkgconfig files.
+
+- Ported the interactive-wayland demo program to v6 of the xdg-shell
+  protocol.
+
+- Added new keysym definitions from xproto.
+
+- New API:
+  XKB_KEY_XF86Keyboard
+  XKB_KEY_XF86WWAN
+  XKB_KEY_XF86RFKill
+  XKB_KEY_XF86AudioPreset
+
+
+libxkbcommon 0.7.1 - 2017-01-18
+==================
+
+- Fixed various reported problems when the current locale is tr_TR.UTF-8.
+
+  The function xkb_keysym_from_name() used to perform case-insensitive
+  string comparisons in a locale-dependent way, but required it to to
+  work as in the C/ASCII locale (the so called "Turkish i problem").
+
+  The function is now no longer affected by the current locale.
+
+- Fixed compilation in NetBSD.
+
+
+libxkbcommon 0.7.0 - 2016-11-11
+==================
+
+- Added support for different "modes" of calculating consumed modifiers.
+  The existing mode, based on the XKB standard, has proven to be
+  unintuitive in various shortcut implementations.
+
+  A new mode, based on the calculation used by the GTK toolkit, is added.
+  This mode is less eager to declare a modifier as consumed.
+
+- Added a new interactive demo program using the Wayland protocol.
+  See the PACKAGING file for the new (optional) test dependencies.
+
+- Fixed a compilation error on GNU Hurd.
+
+- New API:
+  enum xkb_consumed_mode
+  XKB_CONSUMED_MODE_XKB
+  XKB_CONSUMED_MODE_GTK
+  xkb_state_key_get_consumed_mods2
+  xkb_state_mod_index_is_consumed2
+
+
+libxkbcommon 0.6.1 - 2016-04-08
+==================
+
+- Added LICENSE to distributed files in tarball releases.
+
+- Minor typo fix in xkb_keymap_get_as_string() documentation.
+
+
+libxkbcommon 0.6.0 - 2016-03-16
+==================
+
+- If the XKB_CONFIG_ROOT environment variable is set, it is used as the XKB
+  configuration root instead of the path determined at build time.
+
+- Tests and benchmarks now build correctly on OSX.
+
+- An XKB keymap provides a name for each key it defines.  Traditionally,
+  these names are limited to at most 4 characters, and are thus somewhat
+  obscure, but might still be useful (xkbcommon lifts the 4 character limit).
+
+  The new functions xkb_keymap_key_get_name() and xkb_keymap_key_by_name()
+  can be used to get the name of a key or find a key by name.  Note that
+  a key may have aliases.
+
+- Documentation improvements.
+
+- New API:
+  xkb_keymap_key_by_name()
+  xkb_keymap_key_get_name()
+
+
+libxkbcommon 0.5.0 - 2014-10-18
+==================
+
+- Added support for Compose/dead keys in a new module (included in
+  libxkbcommon). See the documentation or the
+  xkbcommon/xkbcommon-compose.h header file for more details.
+
+- Improved and reordered some sections of the documentation.
+
+- The doxygen HTML pages were made nicer to read.
+
+- Most tests now run also on non-linux platforms.
+
+- A warning is emitted by default about RMLVO values which are not used
+  during keymap compilation, which are most often a user misconfiguration.
+  For example, "terminate:ctrl_alt_backspace" instead of
+  "terminate:ctrl_alt_bksp".
+
+- Added symbol versioning for libxkbcommon and libxkbcommon-x11.
+  Note: binaries compiled against this and future versions will not be
+  able to link against the previous versions of the library.
+
+- Removed several compatablity symbols from the binary (the API isn't
+  affected). This affects binaries which
+
+  1. Were compiled against a pre-stable (<0.2.0) version of libxkbcommon, and
+  2. Are linked against the this or later version of libxkbcommon.
+
+  Such a scenario is likely to fail already.
+
+- If Xvfb is not available, the x11comp test is now correctly skipped
+  instead of hanging.
+
+- Benchmarks were moved to a separate bench/ directory.
+
+- Build fixes from OpenBSD.
+
+- Fixed a bug where key type entries such as "map[None] = Level2;" were
+  ignored.
+
+- New API:
+  XKB_COMPOSE_*
+  xkb_compose_*
+
+
+libxkbcommon 0.4.3 - 2014-08-19
+==================
+
+- Fixed a bug which caused xkb_x11_keymap_new_from_device() to misrepresent
+  modifiers for some keymaps.
+
+  https://github.com/xkbcommon/libxkbcommon/issues/9
+
+- Fixed a bug which caused xkb_x11_keymap_new_from_device() to ignore XKB
+  PrivateAction's.
+
+- Modifiers are now always fully resolved after xkb_state_update_mask().
+  Previously the given state components were used as-is, without
+  considering virtual modifier mappings.
+  Note: this only affects non-standard uses of xkb_state_update_mask().
+
+- Added a test for xkbcommon-x11, "x11comp". The test uses the system's
+  Xvfb server and xkbcomp. If they do not exist or fail, the test is
+  skipped.
+
+- Fixed memory leaks after parse errors in the XKB yacc parser.
+  The fix required changes which are currently incompatible with byacc.
+
+
+libxkbcommon 0.4.2 - 2014-05-15
+==================
+
+- Fixed a bug where explicitly passing "--enable-x11" to ./configure would
+  in fact disable it (regressed in 0.4.1).
+
+- Added @since version annotations to the API documentation for everything
+  introduced after the initial stable release (0.2.0).
+
+- Added a section to the documentation about keysym transformations, and
+  clarified which functions perform a given transformation.
+
+- XKB files which fail to compile during keymap construction can no longer
+  have any effect on the resulting keymap: changes are only applied when
+  the entire compilation succeeds.
+  Note: this was a minor correctness issue inherited from xkbcomp.
+
+- Fix an out-of-bounds array access in src/x11/util.c:adopt_atoms()
+  error-handling code.
+  Note: it seems impossible to trigger in the current code since the input
+  size cannot exceed the required size.

 # libxkbcommon
 
-xkbcommon is a keymap compiler and support library which processes a
-reduced subset of keymaps as defined by the XKB specification.  Primarily,
-a keymap is created from a set of Rules/Model/Layout/Variant/Options names,
-processed through an XKB ruleset, and compiled into a struct xkb_keymap,
-which is the base type for all xkbcommon operations.
-
-From an xkb_keymap, an xkb_state object is created which holds the current
-state of all modifiers, groups, LEDs, etc, relating to that keymap.  All
-key events must be fed into the xkb_state object using xkb_state_update_key().
-Once this is done, the xkb_state object will be properly updated, and the
-keysyms to use can be obtained with xkb_state_key_get_syms().
-
-libxkbcommon does not distribute a dataset itself, other than for testing
-purposes.  The most common dataset is xkeyboard-config, as used by all
-current distributions for their X11 XKB data.  More information on
-xkeyboard-config is available here:
-    http://www.freedesktop.org/wiki/Software/XKeyboardConfig
+libxkbcommon is a keyboard keymap compiler and support library which
+processes a reduced subset of keymaps as defined by the XKB (X Keyboard
+Extension) specification.  It also contains a module for handling Compose
+and dead keys.
 
 ## Quick Guide
 
 See [Quick Guide](doc/quick-guide.md).
 
+## Building
+
+libxkbcommon is built with [Meson](http://mesonbuild.com/):
+
+    meson setup build
+    ninja -C build
+
+To build for use with Wayland, you can disable X11 support while still
+using the X11 keyboard configuration resource files thusly:
+
+    meson setup build \
+        -Denable-x11=false \
+        -Dxkb-config-root=/usr/share/X11/xkb \
+        -Dx-locale-root=/usr/share/X11/locale
+    ninja -C build
+
 ## API
 
-While xkbcommon's API is somewhat derived from the classic XKB API as found
+While libxkbcommon's API is somewhat derived from the classic XKB API as found
 in X11/extensions/XKB.h and friends, it has been substantially reworked to
-expose fewer internal details to clients.  The supported API is available
-in the xkbcommon/xkbcommon-*.h files.  Additional support is provided for
-X11 (XCB) clients, in the xkbcommon-x11 library, xkbcommon/xkbcommon-x11.h.
-
-The xkbcommon API and ABI are stable. We will attempt to not break ABI during
-a minor release series, so applications written against 0.1.0 should be
-completely compatible with 0.5.3, but not necessarily with 1.0.0.  However, new
-symbols may be introduced in any release.  Thus, anyone packaging xkbcommon
-should make sure any package depending on it depends on a release greater than
-or equal to the version it was built against (or earlier, if it doesn't use
-any newly-introduced symbols), but less than the next major release.
+expose fewer internal details to clients.
+
+See the [API Documentation](https://xkbcommon.org/doc/current/modules.html).
+
+## Dataset
+
+libxkbcommon does not distribute a keymap dataset itself, other than for
+testing purposes.  The most common dataset is xkeyboard-config, which is used
+by all current distributions for their X11 XKB data.  More information on
+xkeyboard-config is available here:
+    https://www.freedesktop.org/wiki/Software/XKeyboardConfig
+
+The dataset for Compose is distributed in libX11, as part of the X locale
+data.
 
 ## Relation to X11
 
-Relative to the XKB 1.1 specification implemented in current X servers,
-xkbcommon has removed support for some parts of the specification which
-introduced unnecessary complications.  Many of these removals were in fact
-not implemented, or half-implemented at best, as well as being totally
-unused in the standard dataset.
-
-Notable removals:
-- geometry support
-  + there were very few geometry definitions available, and while
-    xkbcommon was responsible for parsing this insanely complex format,
-    it never actually did anything with it
-  + hopefully someone will develop a companion library which supports
-    keyboard geometries in a more useful format
-- KcCGST (keycodes/compat/geometry/symbols/types) API
-  + use RMLVO instead; KcCGST is now an implementation detail
-  + including pre-defined keymap files
-- XKM support
-  + may come in an optional X11 support/compatibility library
-- around half of the interpret actions
-  + pointer device, message and redirect actions in particular
-- non-virtual modifiers
-  + core and virtual modifiers have been collapsed into the same
-    namespace, with a 'significant' flag that largely parallels the
-    core/virtual split
-- radio groups
-  + completely unused in current keymaps, never fully implemented
-- overlays
-  + almost completely unused in current keymaps
-- key behaviors
-  + used to implement radio groups and overlays, and to deal with things
-    like keys that physically lock; unused in current keymaps
-- indicator behaviours such as LED-controls-key
-  + the only supported LED behaviour is key-controls-LED; again this
-    was never really used in current keymaps
-
-Notable additions:
-- 32-bit keycodes
-- extended number of modifiers
-- extended number of groups
-- multiple keysyms per level
-  + this requires incompatible dataset changes, such that X11 would
-    not be able to parse these
+See [Compatibility](doc/compat.md) notes.

+/**
+ * @page compose-overview Overview
+ * @parblock
+ *
+ * Compose and dead-keys are a common feature of many keyboard input
+ * systems.  They extend the range of the keysysm that can be produced
+ * directly from a keyboard by using a sequence of key strokes, instead
+ * of just one.
+ *
+ * Here are some example sequences, in the libX11 Compose file format:
+ *
+ *     <dead_acute> <a>         : "á"   aacute # LATIN SMALL LETTER A WITH ACUTE
+ *     <Multi_key> <A> <T>      : "@"   at     # COMMERCIAL AT
+ *
+ * When the user presses a key which produces the `<dead_acute>` keysym,
+ * nothing initially happens (thus the key is dubbed a "dead-key").  But
+ * when the user enters `<a>`, "á" is "composed", in place of "a".  If
+ * instead the user had entered a keysym which does not follow
+ * `<dead_acute>` in any compose sequence, the sequence is said to be
+ * "cancelled".
+ *
+ * Compose files define many such sequences.  For a description of the
+ * common file format for Compose files, see the Compose(5) man page.
+ *
+ * A successfuly-composed sequence has two results: a keysym and a UTF-8
+ * string.  At least one of the two is defined for each sequence.  If only
+ * a keysym is given, the keysym's string representation is used for the
+ * result string (using xkb_keysym_to_utf8()).
+ *
+ * This library provides low-level support for Compose file parsing and
+ * processing.  Higher-level APIs (such as libX11's `Xutf8LookupString`(3))
+ * may be built upon it, or it can be used directly.
+ *
+ * @endparblock
+ */
+
+/**
+ * @page compose-conflicting Conflicting Sequences
+ * @parblock
+ *
+ * To avoid ambiguity, a sequence is not allowed to be a prefix of another.
+ * In such a case, the conflict is resolved thus:
+ *
+ * 1. A longer sequence overrides a shorter one.
+ * 2. An equal sequence overrides an existing one.
+ * 3. A shorter sequence does not override a longer one.
+ *
+ * Sequences of length 1 are allowed.
+ *
+ * @endparblock
+ */
+
+/**
+ * @page compose-cancellation Cancellation Behavior
+ * @parblock
+ *
+ * What should happen when a sequence is cancelled?  For example, consider
+ * there are only the above sequences, and the input keysyms are
+ * `<dead_acute> <b>`.  There are a few approaches:
+ *
+ * 1. Swallow the cancelling keysym; that is, no keysym is produced.
+ *    This is the approach taken by libX11.
+ * 2. Let the cancelling keysym through; that is, `<b>` is produced.
+ * 3. Replay the entire sequence; that is, `<dead_acute> <b>` is produced.
+ *    This is the approach taken by Microsoft Windows (approximately;
+ *    instead of `<dead_acute>`, the underlying key is used.  This is
+ *    difficult to simulate with XKB keymaps).
+ *
+ * You can program whichever approach best fits users' expectations.

+ * @page compose-locale Compose Locale
+ * @parblock
+ *
+ * Compose files are locale dependent:
+ * - Compose files are written for a locale, and the locale is used when
+ *   searching for the appropriate file to use.
+ * - Compose files may reference the locale internally, with directives
+ *   such as \%L.
+ *
+ * As such, functions like xkb_compose_table_new_from_locale() require
+ * a `locale` parameter.  This will usually be the current locale (see
+ * locale(7) for more details).  You may also want to allow the user to
+ * explicitly configure it, so he can use the Compose file of a given
+ * locale, but not use that locale for other things.
+ *
+ * You may query the current locale as follows:
+ * @code
+ *     const char *locale;
+ *     locale = setlocale(LC_CTYPE, NULL);
+ * @endcode
+ *
+ * This will only give useful results if the program had previously set
+ * the current locale using setlocale(3), with `LC_CTYPE` or `LC_ALL`
+ * and a non-NULL argument.
+ *
+ * If you prefer not to use the locale system of the C runtime library,
+ * you may nevertheless obtain the user's locale directly using
+ * environment variables, as described in locale(7).  For example,
+ * @code
+ *     const char *locale;
+ *     locale = getenv("LC_ALL");
+ *     if (!locale || !*locale)
+ *         locale = getenv("LC_CTYPE");
+ *     if (!locale || !*locale)
+ *         locale = getenv("LANG");
+ *     if (!locale || !*locale)
+ *         locale = "C";
+ * @endcode
+ *
+ * Note that some locales supported by the C standard library may not
+ * have a Compose file assigned.

 /**
+ * @page x11-overview Overview
+ * @parblock
+ *
+ * The xkbcommon-x11 module provides a means for creating an xkb_keymap
+ * corresponding to the currently active keymap on the X server.  To do
+ * so, it queries the XKB X11 extension using the xcb-xkb library.  It
+ * can be used as a replacement for Xlib's keyboard handling.
+ *
+ * Following is an example workflow using xkbcommon-x11.  A complete
+ * example may be found in the test/interactive-x11.c file in the
+ * xkbcommon source repository.  On startup:
+ *
+ * 1. Connect to the X server using xcb_connect().
+ * 2. Setup the XKB X11 extension.  You can do this either by using the
+ *    xcb_xkb_use_extension() request directly, or by using the
+ *    xkb_x11_setup_xkb_extension() helper function.
+ *
+ * The XKB extension supports using separate keymaps and states for
+ * different keyboard devices.  The devices are identified by an integer
+ * device ID and are managed by another X11 extension, XInput. The
+ * original X11 protocol only had one keyboard device, called the "core
+ * keyboard", which is still supported as a "virtual device".
+ *
+ * 3. We will use the core keyboard as an example.  To get its device ID,
+ *    use either the xcb_xkb_get_device_info() request directly, or the
+ *    xkb_x11_get_core_keyboard_device_id() helper function.
+ * 4. Create an initial xkb_keymap for this device, using the
+ *    xkb_x11_keymap_new_from_device() function.
+ * 5. Create an initial xkb_state for this device, using the
+ *    xkb_x11_state_new_from_device() function.
+ *
+ * @note At this point, you may consider setting various XKB controls and
+ * XKB per-client flags.  For example, enabling detectable autorepeat: \n
+ * https://www.x.org/releases/current/doc/kbproto/xkbproto.html#Detectable_Autorepeat
+ *
+ * Next, you need to react to state changes (e.g. a modifier was pressed,
+ * the layout was changed) and to keymap changes (e.g. a tool like xkbcomp,
+ * setxkbmap or xmodmap was used):
+ *
+ * 6. Select to listen to at least the following XKB events:
+ *    NewKeyboardNotify, MapNotify, StateNotify; using the
+ *    xcb_xkb_select_events_aux() request.
+ * 7. When NewKeyboardNotify or MapNotify are received, recreate the
+ *    xkb_keymap and xkb_state as described above.
+ * 8. When StateNotify is received, update the xkb_state accordingly
+ *    using the xkb_state_update_mask() function.
+ *
+ * @note It is also possible to use the KeyPress/KeyRelease @p state
+ * field to find the effective modifier and layout state, instead of
+ * using XkbStateNotify: \n
+ * https://www.x.org/releases/current/doc/kbproto/xkbproto.html#Computing_A_State_Field_from_an_XKB_State
+ * \n However, XkbStateNotify is more accurate.
+ *
+ * @note There is no need to call xkb_state_update_key(); the state is
+ * already synchronized.
+ *
+ * Finally, when a key event is received, you can use ordinary xkbcommon
+ * functions, like xkb_state_key_get_one_sym() and xkb_state_key_get_utf8(),
+ * as you normally would.

  * understand why, consider some requirements from a standard shortcut

  *
- * 1. The shortcut's modifiers must match exactly to the state. For example,
- *    it is possible to bind separate actions to \<Alt\>\<Tab\> and to
- *    \<Alt\>\<Shift\>\<Tab\>. Further, if only \<Alt\>\<Tab\> is bound to
- *    an action, pressing \<Alt\>\<Shift\>\<Tab\> should not trigger the

  *    Effectively, this means that the modifiers are compared using the
  *    equality operator (==).
- * 2. Only relevant modifiers are considered for the matching. For example,

+ * 2. Only relevant modifiers are considered for the matching.  For example,
  *    Caps Lock and Num Lock should not generally affect the matching, e.g.
  *    when matching \<Alt\>\<Tab\> against the state, it does not matter
- *    whether Num Lock is active or not. These relevant, or significant,
+ *    whether Num Lock is active or not.  These relevant, or "significant",
  *    modifiers usually include Alt, Control, Shift, Super and similar.
  *    Effectively, this means that non-significant modifiers are masked out,
  *    before doing the comparison as described above.
- * 3. The matching must be independent of the layout/keymap. For example,
+ *
+ * 3. The matching must be independent of the layout/keymap.  For example,
  *    the \<Plus\> (+) symbol is found on the first level on some layouts,
- *    and requires holding Shift on others. If you simply bind the action
+ *    but requires holding Shift on others.  If you simply bind the action
  *    to the \<Plus\> keysym, it would work for the unshifted kind, but
- *    not for the others, because the match against Shift would fail. If
+ *    not for the others, because the match against Shift would fail.  If
  *    you bind the action to \<Shift\>\<Plus\>, only the shifted kind would
- *    work. So what is needed is to recognize that Shift is used up in the
+ *    work.  So what is needed is to recognize that Shift is used up in the
  *    translation of the keysym itself, and therefore should not be included
  *    in the matching.
  *    Effectively, this means that consumed modifiers (Shift in this example)
  *    are masked out as well, before doing the comparison.
  *
- * To summarize, this is how the matching would be performed:
+ * In summary, this is approximately how the matching would be performed:

  *   (keysym == shortcut_keysym) &&

+From: Oliver Wolff <oliver.wolff@qt.io>
+Date: Wed, 22 Aug 2018 09:21:04 +0200
+Subject: [PATCH 1/8] ANGLE: Use pixel sizes in the XAML swap chain
+
+This is necessary for Qt applications, as they render to GL in physical
+pixels. This is consistent with the CoreWindow swap chain behavior.
+
+In order to achieve proper scaling, the scale factor has to be initialized
+properly in InspectableNativeWindow.
+
+This change only affects Windows Runtime targets.

-Subject: [PATCH 4/7] ANGLE: Allow Windows Phone to communicate swap region
-
-eglPostSubBufferNV is used to communicate the size of the window, as
-otherwise there is no way for the renderer to know if the last frame was
-rendered in landscape or portrait, causing rendering glitches when the
-orientation changes. The rotation flags are utilized in a few additional
-places now to fix some corner cases where the rotation was not applied.
-
-This patch should be squashed into "ANGLE-Improve-Windows-Phone-Support"
-during the next ANGLE rebase.

-Subject: [PATCH] ANGLE: Use pixel sizes in the XAML swap chain
-
-This is necessary for Qt applications, as they render to GL in physical
-pixels. This is consistent with the CoreWindow swap chain behavior.
-
-This includes a partial revert of "ANGLE: Improve Windows Phone Support"
-as the modifications to SwapChain11 are incompatible with the XAML swap
-chain.
-
-This change only affects Windows Runtime targets.

+Subject: [PATCH] Revert "Fix scanForWantedComponents not ignoring
+ attribute values of 0."
+
+This patch reverts commit 2648d9297f25a0d1fa2837f020975a45d4e8a8b9 as a
+workaround for the "banding" artifacts we were seeing in Qt. Angle
+returns a list of supported graphic formats or configurations, sorting
+it in a way that the first one should be the one that fits better the
+requested format. In Qt we use the first thing we receive in the list.
+In the current Angle version, however, a fix has changed the way in
+which the list is sorted. In the old version the first element would be
+a 32-bit graphic format, while now it's a 16-bit one, resulting in the
+"banding" artifacts. The workaround reverts back to the previous sorting
+behavior.

+Subject: [PATCH] ANGLE: Disable multisampling to avoid crash in Qt
+ applications
+
+This patch adds a workaround for the crash that occurs with multisampling
+enabled in some Qt applications (e.g., the 2dpainting example). The old
+Angle release we were using lacked support for multisampling, so it was
+ignored when requested. This current version seems to support it, but is
+causing a crash in the D3D11 shaders, so this workaround disables that
+support.

-Subject: [PATCH] ANGLE: Use ANGLE_D3D11_QDTD_AVAILABLE to check struct's
- availability
-
-Checking mingw when defining the structure is not enough, as it is
-available in recent versions of MinGW. The define that is used is set
-depending on a configure test which works independently of the used
-toolchain.

     In the first line in snippet above, a file URL is constructed from a
     local, relative path. A file URL with a relative path only makes sense
     if there is a base URL to resolve it against. For example:
 
-    \code
-    QUrl url = QUrl::fromLocalFile("file.txt");
-    QUrl baseUrl = QUrl("file:/home/user/");
-    // wrong: prints QUrl("file:file.txt"), as url already has a scheme
-    qDebug() << baseUrl.resolved(url);
-    \endcode
+    \snippet code/src_corelib_io_qurl.cpp 17
 
     To resolve such a URL, it's necessary to remove the scheme beforehand:
 
-    \code
-    // correct: prints QUrl("file:///home/user/file.txt")
-    url.setScheme(QString());
-    qDebug() << baseUrl.resolved(url);
-    \endcode
+    \snippet code/src_corelib_io_qurl.cpp 18
 
     For this reason, it is better to use a relative URL (that is, no scheme)
     for relative file paths:

-    QUrl url = QUrl("file.txt");
-    QUrl baseUrl = QUrl("file:/home/user/");

+    \internal
+
+    Lock-free event passing:
+
+    The lock-free solution uses a singly-linked list to pass events from the
+    reader thread to the main thread. An atomic operation is used to sync the
+    tail node of the list between threads. The reader thread takes special care
+    when accessing the tail node. It does not dequeue the last node and does not
+    access (read or write) the tail node's 'next' member. This lets the reader
+    add more items at the same time as the main thread is dequeuing nodes from
+    the head. A custom linked list implementation is used, because QLinkedList
+    does not have any thread-safety guarantees and the custom list is more
+    lightweight - no reference counting, back links, etc.
+
+    Memory management:
+
+    In a normally functioning application, XCB plugin won't buffer more than few
+    batches of events, couple events per batch. Instead of constantly calling
+    new / delete, we can create a pool of nodes that we reuse. The main thread
+    uses an atomic operation to sync how many nodes have been restored (available
+    for reuse). If at some point a user application will block the main thread
+    for a long time, we might run out of nodes in the pool. Then we create nodes
+    on a heap. These will be automatically "garbage collected" out of the linked
+    list, once the main thread stops blocking.
