Rather than trying to use designated initializers, zero init the
msghdr variable and fill in its fields. This makes sure to zero-init any
padding bytes, and fixes a compilation error on musl-libc based systems.
This is to differentiate between the upcoming `AllocatingMemoryStream`,
which automatically allocates memory as needed instead of operating on a
static memory area.
This patch introduces error propagation to Gfx::SystemTheme to remove
instances of release_value_but_fixme_should_propagate_errors().
Userland applications that have been affected by this change have been
updated to utilise this propagation and as a result 4 such instances of
the aforementioned method have been removed.
Store the ratio between device and CSS pixels on the PaintContext, so
that it can convert between the two.

This generally seems like a better name, especially if we somehow also
need a better name for "read the entire buffer, but not the entire file"
somewhere down the line.
This deduplicates argument handling logic from Help and man and makes it
more modular for future use cases. The argument handling works as
before: two arguments specify section and page (in this order), one
argument specifies either a page (the first section that it's found in
is used) or a path to a manpage markdown file.
...and also for hit testing, which is involved in most of them.
Much of this is temporary conversions and other awkwardness, which
should resolve itself as the rest of LibWeb is converted to these new
types. Hopefully. :thousandyakstare:
This is a first step towards handling PNG encoding failures instead of
just falling over and crashing the program.
This initial step will cause encode() to return an error if the final
ByteBuffer copy fails to allocate. There are more potential failures
that will be surfaced by subsequent commits.
Two FIXMEs were killed in the making of this patch. :^)
`Core::Stream::File` shouldn't hold any utility methods that are
unrelated to constructing a `Core::Stream`, so let's just replace the
existing `Core::File::exists` with the nicer looking implementation.
Note that js_rope_string() has been folded into this, the old name was
misleading - it would not always create a rope string, only if both
sides are not empty strings. Use a three-argument create() overload
instead.
The sql REPL had the created/updated rows swapped by mistake. Also make
sure SQLServer fills in the correct value depending on the executed
command, and that the DELETE command indicates the rows it deleted.
We've been sending the values converted to a string, but now that the
Value type is transferrable over IPC, send the values themselves. Any
client that wants the value as a string may do so easily, whereas this
will allow less trivial clients to avoid string parsing.
Currently, when clients connect to SQL server, we inform them of any
errors opening the database via an asynchronous IPC. But we already know
about these errors before returning from the connect() IPC, so this
roundabout propagation is a bit unnecessary. Now if we fail to open the
database, we will simply not send back a valid connection ID.
Disconnect has a similar story. Rather than disconnecting and invoking
an asynchronous IPC to inform the client of the disconnect, make the
disconnect() IPC synchronous (because all it does is remove the database
from the map of open databases). Further, the only user of this command
is the SQL REPL when it wants to connect to a different database, so it
makes sense to block it. This did require moving a bit of logic around
in the REPL to accommodate this change.
In order to execute a prepared statement multiple times, and track each
execution's results, clients will need to be provided an execution ID.
This will create a monotonically increasing ID each time a prepared
statement is executed for this purpose.
When storing IDs and sending values over IPC, this changes SQLServer to:
1. Stop using -1 as a nominal "bad" ID. Store the IDs as unsigned, and
use Optional in the one place that the IPC needs to indicate an ID
was not allocated.
2. Let LibIPC encode/decode enumerations (SQLErrorCode) on our behalf.
3. Use size_t for array sizes.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Rename sql_statement to prepare_statement and statement_execute to
execute_statement. The former aligns more with other database libraries
(e.g. Java's JDBC prepareStatement). The latter reads less awkwardly.
This changes this:
```sh
profile -c "python3 -m test test_dict"
```
to this:
```sh
profile -- python3 -m test test_dict
```
This should be less confusing, hopefully!
This patch adds the "-n"/"--head-count" optional argument to specifiy
the maximum number of shuffled lines to output.
Idea from Andreas' FIXME roulette :^)
This utility essentially creates a filesystem sandbox for a specified
command, so it can be tested with only the unveiled paths the user
specifies beforehand.
