Unlike other BCP47 keywords that we are parsing, these only appear in
the BCP47 XML file itself within the CLDR. The values are very simple
though, so just hard code them until the Unicode org re-releases the
CLDR with BCP47: https://unicode-org.atlassian.net/browse/CLDR-15158
This commit removes the usage of HashMap in Mutex, thereby making Mutex
be allocation-free.
In order to achieve this several simplifications were made to Mutex,
removing unused code-paths and extra VERIFYs:
* We no longer support 'upgrading' a shared lock holder to an
exclusive holder when it is the only shared holder and it did not
unlock the lock before relocking it as exclusive. NOTE: Unlike the
rest of these changes, this scenario is not VERIFY-able in an
allocation-free way, as a result the new LOCK_SHARED_UPGRADE_DEBUG
debug flag was added, this flag lets Mutex allocate in order to
detect such cases when debugging a deadlock.
* We no longer support checking if a Mutex is locked by the current
thread when the Mutex was not locked exclusively, the shared version
of this check was not used anywhere.
* We no longer support force unlocking/relocking a Mutex if the Mutex
was not locked exclusively, the shared version of these functions
was not used anywhere.
Devices such as NVMe can have blocks bigger that 512. Use the
m_block_size variable in read/write_block function instead of the
hardcoded 512 block size.
Previously, given a malformed IPC call declaration, where a parameter
does not have a name, the IPCCompiler would spin endlessly while
consuming more and more memory.
This is because it parses the parameter type incorrectly
(it consumes superfluous characters into the parameter type).
An example for such malformed declaration is:
tokens_info_result(Vector<GUI::AutocompleteProvider::TokenInfo>) =|
As a temporary fix, this adds VERIFY calls that would fail if we're at
EOF when parsing parameter names.
A real solution would be to parse C++ parameter types correctly.
LibCpp's Parser could be used for this task.
This is being used by GUID partitions so the first three dash-delimited
fields of the GUID are stored in little endian order but the last two
fields are stored in big endian order, hence it's a representation which
is mixed.
This patch adds a painting delegate to the icon column of CommandPalette
to show a radio button in case an action is checkable and does not
explicitly have an icon :^)
The previous solution of "lol whats a UB" was not nice and tripped over
itself when it was run under UBSAN, fix this by doing explicit
byte-by-byte reads where needed.
Ideally the x86 fault handler would only do x86 specific things and
delegate the rest of the work to MemoryManager. This patch moves some of
the address checks to a more generic place.
