Joining dead threads is allowed for two main reasons:
- Thread join behavior should not be racy when a thread is joined and
exiting at roughly the same time. This is common behavior when threads
are given a signal to end (meaning they are going to exit ASAP) and
then joined.
- POSIX requires that exited threads are joinable (at least, there is no
language in the specification forbidding it).
The behavior is still well-defined; e.g. it doesn't allow a dead
detached thread to be joined or a thread to be joined more than once.
This is just used to key the socket fd for system server takeover. On
macOS, this file path has a space in it, which trips up the parsing as
it splits on spaces. That parsing should be fixed (probably shouldn't
rely on spaces as a delimter), but for now, we can change the key to
avoid spaces.
Previously, the word was highlighted red in case it was not found in the
dictionary. That color was repurposed as a general "invalid input" color
to nudge the player that something was wrong with the last input.
Accordingly, the field m_last_word_not_in_dictionary was renamed to
m_last_word_invalid
In the "inspiration" for this game, messages are displayed on top of the
game area in case an invalid guess is inputted. After a few seconds,
they disappear. In a similar fashion, a statusbar is created on the game
window and similar messages are outputted there.
Even if block has all children inline there need to be a check
if it creates BFC because otherwise IFC will be looking in
wrong parent BFC to calculate space used by floats.
We previously passed both OperandSize and AddressSize to the
constructor.
Both values were only ever 32-bit at construction.
We used AddressSize::Size64 to signify Long mode which was needlessly
complicated.
As the existing near-by comment says, the default size of displacements
& immediates is 32 bits even in Long mode.
This makes `disasm` work on our binaries in x86-64 builds.
This adds shortcut for inserting a new empty indented line
above/below current cursor position.
- <Ctrl-Return> for inserting line below.
- <Ctrl-Shift-Return> for inserting line above.
Added in d522a6f and 1e604b7, their purpose snuffed out in 11bb88f
like the faint pulse of a pleading candle, two lives of short excess,
doomed to itemize their sins to no effect and for all eternity...
Note that Jakt only allows StringView creation from string literals, so
none of the invariants in the class are broken by this (if used only
from within Jakt).
This allows the user to transform the contents of the optional (if any
exists), without manually unwrapping and then rewrapping it.
This is needed by the Jakt runtime.
This is used in Jakt, and providing that value from Jakt's side is more
trouble than doing this.
Considering this class is bound to go away, a little
backwards-compatible API change is just fine.
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.
- Calculate the full name on demand
- Make section and name protected
- Reorder some members logically
- Change the name getter to be fallible, as some implementors need to
allocate
The previous moved-from state was the null string. This violates both
our invariant that String is never null, and also the C++ contract that
the moved-from state must be valid but unspecified. The empty short
string state is of course valid, so it satisfies both invariants. It
also allows us to remove any extra checks for the null state.
The reason this change is made is primarily because swap() requires
moved-from objects to be reassignable (C++ allows this). Because the
move assignment of String would not check the null state, it crashed
trying to increment the data reference count (nullptr signals a
non-short string). This meant that e.g. quick_sort'ing String would
crash immediately.

Comparing UTF-8 can be done by simple byte lexicographic comparison per
definition, so we just piggy-back on StringView's high-performance
comparator.
This is a first step in deduplicating code within and across Help and
man.
Because LibManual also doesn't contain any DeprecatedString, some
adjustments to Help's string handling is included, just to interoperate
with LibManual better. Further work in this area mostly requires String
APIs in LibGUI.
On Serenity, SQLServer is started by SystemServer. But on Lagom, it is
manually started by e.g. Ladybird when the application is started, and
killed when the application exits. This means every Ladybird process
starts its own SQLServer, which defeats the purpose of SQLServer acting
as the single process interacting with the database files.
This patch will allow SQLClient to start up a single SQLServer instance,
first checking if one already exists. If it does exist, SQLClient will
simply connect to SQLServer's socket. If it does not exist, SQLClient
will launch SQLServer much like SystemServer would (with a local socket
file, etc.).
The child SQLServer process is double-forked; the grandchild process
becomes the SQLServer process, which the middle child process simply
exits to "detach" the grandchild process from the SQLClient process.
Currently, we create a new SQL::Database object for each database we are
requested to open. When multiple clients connect to the same database,
the same underlying database file is opened and cached each time. This
results in updates from one client not being propagated to others.
To prevent this, when a database is requested to be open, check if it is
already open. We can then re-use that SQL::Database object for the new
connection.
