HackStudio can now detect that files that have been opened in it were
deleted. When this occurs, it will update the list of open files and
reasign a file to the editors that showed the deleted file before the
deletion. The new file is either another file that was opened or the
default editor is no other open file is available
Closes SerenityOS#6632
The dance here is not complicated, but it is something that should
be taken note of. Since we append to both lists, we don't want to
orphan the new Inode in the m_links/m_subfolders Vector in the event
that the append to m_parent_fs.m_nodes fails.
According to POSIX.1 all error codes have to be distinct - with
the exception for EAGAIN and EWOULDBLOCK. Other libcs including
eglibc and newlib define EWOULDBLOCK as an alias for EAGAIN and
some software including OpenTTD expect this behavior.
When the default build location was moved from /Build to the new
architecture specific directory, /Build/i686, this code broke.
All file names are now path relative one additional level up.
So continue the hack, and introduce another dummy directory to
make the relative paths resolve correctly.
Updated Spreadsheet to use the new way of converting a number to a
String represenation using the alphabet.
The code responsible for this conversion now lives in AK/String, so it
gets deleted from Spreadsheet.cpp.
This allows everybody to create a String version of their number
in a arbitrary bijective base. Bijective base meaning that the mapping
doesn't have a 0. In the usual mapping to the alphabet the follower
after 'Z' is 'AA'.
The mapping using the (uppercase) alphabet is used as a standard but
can be overridden specifying 'base' and 'map'.
The code was directly yanked from the Spreadsheet.
The Fire, LibGfxDemo and LibGfxScaleDemo demos did not have Alt+F4
functionality as they lacked menubars - I just added basic menubars with
Quit entries to allow this shortcut with the demos that didn't have it.
Raw sockets don't need a local port, so we shouldn't fail operations
if allocation yields an ENOPROTOOPT.
I'm not in love with the factoring here, just patching up the bug.
Without this patch we end up with sockets in the listener's accept
queue with state 'closed' when doing stealth SYN scans:
Client -> Server: SYN for port 22
Server -> Client: SYN/ACK
Client -> Server: RST (i.e. don't complete the TCP handshake)
Just 'github.actor' may or may not be the actual PR author, but
especially since action runs have to be approved for first-time
contributors, it's been giving us a lot of incorrect results.
I have no idea how this _ever_ worked, and I also have no idea why past
me didn't use FileStream to begin with.
Fixes the issue where lots of junk data would be written to the temp
file, causing the external editor to crash.
Most of the existing lint-ing shell scripts have the ability
to only run on the files which have actually changed.
The new port lint-ing script doesn't have this functionality
unfortunately. This forces us to lint ALL the ports on every
single change to any other file in the system if you have
the pre-commit hook setup for your git clone locally.
Instead we can use pre-commit's feature to only run a hook
if certain files have changed to reduce the situations in
which we would run the Meta/lint-ports.py script.
When loading a library at runtime with dlopen(), we now check that:
1. The library's TLS size does not overflow the size of the allocated
TLS block.
2. The Library's TLS data is all zeroed.
We check for both of these cases because we currently do not support
them correctly. When we do add support for them, we can remove these
checks.
This changes the TLS offset calculation logic to be based on the
symbol's size instead of the total size of the TLS.
Because of this change, we no longer need to pipe "m_tls_size" to so
many functions.
Also, After this patch, the TLS data of the main program exists at the
"end" of the TLS block (Highest addresses).
This fixes a part of #6609.
Previously, TLS data was always zero-initialized.
To support initializing the values of TLS data, sys$allocate_tls now
receives a buffer with the desired initial data, and copies it to the
master TLS region of the process.
The DynamicLinker gathers the initial TLS image and passes it to
sys$allocate_tls.
We also now require the size passed to sys$allocate_tls to be
page-aligned, to make things easier. Note that this doesn't waste memory
as the TLS data has to be allocated in separate pages anyway.
This fixes a regression that was introduced in f40ee1b and caused the
tls_offset of all objects other than the main program to be 0.
After this fix map_library's is_program argument is no longer used, so
it was removed.
