This adds a new view mode to profiler which displays source lines and
samples that occured at those lines. This view can be opened via the
menu or by pressing CTRL-S.
It does this by mapping file names from DWARF to "/usr/src/serenity/..."
i.e. source code should be copied to /usr/src/serenity/Userland and
/usr/src/serenity/Kernel to be visible in this mode.
Currently *all* files contributing to the selected function are loaded
completely which could be a lot of data when dealing with lots of
inlined code.
If we do not mark these ranges as reserved, RangeAllocator might later
give us addresses that overlap these, which then causes an assertion
failure in the SoftMMU. This behavior led to recurring CI failures, and
sometimes made programs as simple as `/bin/true` fail.
Fixes "Crash 1" reported in #9104
Previously, if the parent directory didn't exist when making a project,
it would say that the creation directory was 'invalid' which isn't
necessarily true.
This patch prompts the user to ask if they would like to create the
parent directory when creating a project, instead of treating it as an
'invalid' directory.
Most other syscalls pass address arguments as `void*` instead of
`uintptr_t`, so let's do that here too. Besides improving consistency,
this commit makes `strace` correctly pretty-print these arguments in
hex.
This feature was introduced in version 4.17 of the Linux kernel, and
while it's not specified by POSIX, I think it will be a nice addition to
our system.
MAP_FIXED_NOREPLACE provides a less error-prone alternative to
MAP_FIXED: while regular fixed mappings would cause any intersecting
ranges to be unmapped, MAP_FIXED_NOREPLACE returns EEXIST instead. This
ensures that we don't corrupt our process's address space if something
is already at the requested address.
Note that the more portable way to do this is to use regular
MAP_ANONYMOUS, and check afterwards whether the returned address matches
what we wanted. This, however, has a large performance impact on
programs like Wine which try to reserve large portions of the address
space at once, as the non-matching addresses have to be unmapped
separately.
No need to copy and move them around, just to pass them as a
`String const&` to the constructor.
We still end up copying it to a normal String in the end though...
Previously the debuggee process used the same tty of the HackStudio
process.
We now set things up so the debuggee gets attached to the
TerminalWrapper in the "Console" tab.
Previously the setup for both the master and slave pseudoterminals was
done in TerminalWrapper::run_command.
This commit separates the relevant logic into
TerminalWrapper::setup_master_pseudoterminal
and TerminalWrapper::setup_slave_pseudoterminal.
In order to reduce our reliance on __builtin_{ffs, clz, ctz, popcount},
this commit removes all calls to these functions and replaces them with
the equivalent functions in AK/BuiltinWrappers.h.
This option is already enabled when building Lagom, so let's enable it
for the main build too. We will no longer be surprised by Lagom Clang
CI builds failing while everything compiles locally.
Furthermore, the stronger `-Wsuggest-override` warning is enabled in
this commit, which enforces the use of the `override` keyword in all
classes, not just those which already have some methods marked as
`override`. This works with both GCC and Clang.
Persist EditingEngine mode in HackStudio and TextEditor when opening new
files or editing splits. Previously, the EditingEngine defaulted to a
RegularEditingEngine for a new Editor, even if Vim Emulation had been
selected in the existing Editor.
This is an encapsulation of the common work done by all of our
single-client IPC servers on startup:
1. Create a Core::LocalSocket, taking over an accepted fd.
2. Create an application-specific ClientConnection object,
wrapping the socket.
It's not a huge change in terms of lines saved, but I do feel that it
improves expressiveness. :^)
Normally, it's the TTY layer's job to translate '\n' into the separate
'\r' and '\n' control characters needed by the terminal to move the
cursor to the first column of the next line.
(see 5d80debc1f).
In HackStudio, we directly inject data into the TerminalWidget to
display command status. This means that this automatic translation
doesn't happen, so we need to explicitly give it the '\r' too.
When we run the Preprocessor from the CppComprehensionEngine of
the language server, we don't want the preprocessor to crash if it
encounters an invalid preprocessor statement (for example, an #endif
statement without an accompanying previous #if statement).
To achieve this, this commit adds an "ignore_invalid_statements" flag
to the preprocessor which is set by the CppComprehensionEngine.
Fixes#11064.
The maximal crash frequency of the language server was previously 3
seconds, but in practice it was too high.
When working with larger projects the language server can get into a
"crash and respawn" loop that takes more than 3 seconds.
10 seconds seems like a reasonable threshold beyond which we no longer
attempt to respawn the server.
When respawning the language server, we only need to send the content
of opened files to the server.
The on-disk content of files that are not currently open is up to
date, so the server can read them on its own.
