Because ProcFS will refresh the data upon seek to 0, we can re-use
the same file descriptor. This saves us from having to open it every
time, but it also reduces the odds that we are unable to open a new
file descriptor due to low memory conditions.
Rather than crashing with an ASSERT, when we can't read from /proc
we draw the graph with red instead. This also alerts the user that
memory is very low.
When ProcFS could no longer allocate KBuffer objects to serve calls to
read, it would just return 0, indicating EOF. This then triggered
parsing errors because code assumed it read the file.
Because read isn't supposed to return ENOMEM, change ProcFS to populate
the file data upon file open or seek to the beginning. This also means
that calls to open can now return ENOMEM if needed. This allows the
caller to either be able to successfully open the file and read it, or
fail to open it in the first place.
TL;DR: Like clang-format but for GML files :^)
It takes a list of files (or reads from standard input if none is given),
formats them and prints the result to standard output or writes back to
the file when using the -i/--inplace option.
This can be invoked via the Edit menu or with Ctrl+Alt+F. If the current
text in the editor can be parsed as valid GML, it will be formatted and
updated, otherwise an alert is shown (no specific error message as those
are only printed to the debug console in the parser for now).
If the source contains comments, which would be lost after formatting,
the user will be notified and has to confirm the action.
This will be useful for both the Playground app as well as for a
standalone CLI tool (à la clang-format). It cannot handle comments yet
(and will drop them from the formatted output), but other than that it
produces valid GML that matches the formatting we have so far! :^)
Commit a3a9016701 removed the PT_INTERP header
from Loader.so which cleaned up some kernel code in execve. Unfortunately
it prevents Loader.so from being run as an executable
There is a window between dropping the last reference and removing
a ProcFSInode from the lookup map. So, when looking up we need to
check if that Inode is being destructed.
This patch makes hyperlinked terminal cells require a double click
to activate. The appearance of a hovered link is changed to not look
like a classic underlined link, but instead like some kind of typical
double-clickable GUI widget.
Also the hover cursor for links is changed from Hand to Arrow.
A strong symbol anywhere in an executable must override any
weak symbol used in any library. This means that the weak symbol
must be overridden by a strong symbol even if the strong symbol
is in a dependent library. This means we need to perform relocations
twice, and resolve weak symbols globally before attempting to resolve
them locally. Consequentially we need to defer performing any
initialisations until after we have performed the second round of
relocations.
Loader.so now just performs the initial self relocations and static
LibC initialisation before handing over to ELF::DynamicLinker::linker_main
to handle the rest of the process.
As a trade-off, ELF::DynamicLinker needs to be explicitly excluded from
Lagom unless we really want to try writing a cross platform dynamic loader
Browser only uses LaunchServer for one thing: to open the user's
downloads directory after a download is finished.
Eventually I'd like to move this functionality to a separate download
manager service, but for now, let's at least lock down what Browser is
able to ask LaunchServer to do. :^)
Clients of LaunchServer can now provide a list of allowed handlers,
optionally with a specific set of URLs. The list can be sealed to
prevent future additions to it.
If LaunchServer receives a request to open something not on the allowed
handlers list, it will disconnect the client immediately.
The main idea here is to allow otherwise restricted programs to launch
specific things, e.g "Help" to open their manual, or "Browser" to load
the SerenityOS home page. :^)
- Now sorted
- Add a "layout" property to GUI::Widget and GUI::Frame
- Only complete Layouts for the values of "layout"
- Don't suggest anything if the only suggestion is what the user has
already typed
This gets a lot of unecessary includes out of Widget.cpp. Doing this
didn't work before, but improvements in the C library and using dynamic
libraries have likely un-broken it :^).
Also, move the registration global object to an anonymous namespace. No
reason it has to be an extern symbol.
