It's unnecessary to allocate a string when we only want to compare it
with another string.
This change also adds a helper for string literals, so that we won't
need to add -sv suffix everywhere. :^)
...and instead assume it's BGRx8888 or BGRA8888, for now. Always
treating the target as BGRA8888 leads to the alpha channel being
interpreted incorrectly sometimes (as can be seen with WindowServer
overlays).
Fixes#18749
This allows us to create a PlaybackManager from a file which has already
been mapped, instead of passing a file name.
This means that anyone who uses `PlaybackManager` can now use LibFSAC :)
Note that since many low-level bare C APIs are used, null-terminated
strings are still necessary in many places, which sadly required the
addition of many DeprecatedStrings.
Note that in some cases (in particular SQL::Result and PDFErrorOr),
there is no Formatter defined for the error type, hence TRY_OR_FAIL
cannot work as-is. Furthermore, this commit leaves untouched the places
where MUST could be replaced by TRY_OR_FAIL.

This change is supposed to solve the problem that currenty when grid
tracks are interleaved with gaps it is impossible to iterate tracks
spanned by a specific grid item. There is a pair of functions:
gap_adjusted_row() and gap_adjusted_column() but they won't work
when it comes to items spanning > 1 track.
Separating gaps from tracks is going to make it possible to iterate
just tracks or both tracks and gaps when it is required. And now tracks
spanned by an item can be accessed by just index without doing any
additional math.
As IFUNC resolvers may call arbitrary functions though the PLT, they can
only be called after the PLT has been populated. This is true of the
`[[gnu::target_clones]]` attribute, which makes a call to
`__cpu_indicator_init`, which is defined in `libgcc_s.so`, through the
PLT.
`do_plt_relocation` and `do_direct_relocation` are given a parameter
that controls whether IFUNCs are immediately resolved. In the first
pass, relocations pointing to IFUNCs are put on a worklist, while all
other relocations are performed. Only after non-IFUNC relocations are
done and the PLT is set up do we deal with these.
No functional changes intended. This is in preparation of a commit that
overhauls how IFUNCs are resolved.
This commit lets us move the implementation of PLT patching from
`DynamicObject` to `DynamicLoader` where all other relocation code
lives. For this, got[2] now stores the loader's address instead of the
object's.
This is the AArch64 equivalent of `R_X86_64_IRELATIVE`, which specifies
a symbol whose address is determined by calling a local IFUNC resolver
function.
The signature of Core::ProcessStatisticsReader::get_all changed, and
instead of requiring a pointer to an open file, it now needs a bool to
indicate whether usernames should be polled or not. `m_proc_all` was
always converted to `false` in `RefPtr::operator bool()`, so we were
missing usernames for a long time.
The spec says: "The first value gives the width of the corresponding
image, the second value its height. If only one value is given the
second is assumed to be auto."
Fixes#18782
The spec seems to neglect the potential nullity of an image's pending
request in various cases.
Let's protect against crashing and mark these cases with a FIXME about
figuring out whether they are really spec bugs or not.
The expression evaluator is dead code that does nothing but crash on
all paths, as no opcodes are implemented.
Stubbing out the LocListX form fixes a crash while reading DWARF 5
debug data that contains location lists. These are just a new way
to store location expressions, and since we never implemented
expressions, we can just ignore these too.
As far as I can tell this is enough for DWARF 5 to work for us (since
we mainly just use the line tables).
Unwind contexts now remember the lexical and variable environments in
effect when they were created. If an exception is caught, we revert
to those environments in the running execution context.
For `try` statements with a `catch` clause, we were generating *two*
"next" blocks. This meant that not throwing an exception would cause
execution to stop.
Fix this by using the "next" block pointer for the try "entry" and
"handler" blocks.
- Escalator now uses `posix_spawn` instead of `exec`
- Escalator is now able to forward stdin and stdout
- A few general changes to improve code quality
This little program allows us to take the NetworkSettings app away
from being an elevated GUI app.
It receives a JsonObject on STDIN and writes it to the global
Network configuration file.
If the write was successfull it will apply the changes.
At some point `sem_trywait()` changed from returning an error code on
failure to returning -1 and setting the errno. Update test-pthread to
expect this behavior.
