We identify when the universal variable file has changed out from under us by
comparing a bunch of fields from its stat: inode, device, size, high-precision
timestamp, generation. Linux aggressively reuses inodes, and the size may be
the same by coincidence (which is the case in the tests). Also, Linux
officially has nanosecond precision, but in practice it seems to only uses
millisecond precision for storing mtimes. Thus if there are three or more
updates within a millisecond, every field we check may be the same, and we are
vulnerable to the ABA problem. I believe this explains the occasional test
failures.
The solution is to manually set the nanosecond field of the mtime timestamp to
something unlikely to be duplicated, like a random number, or better yet, the
current time (with nanosecond precision). This is more in the spirit of the
timestamp, and it means we're around a million times less likely to collide.
This seems to fix the tests.
input_mapping_execute, when passed false for allow_commands, will return
R_NULL. However currently it does this unconditionally, even if we don't
have any commands. This defeats our read-ahead optimization, so we
always read and process one byte at a time. This caused pasting to be
much slower.
Fixes#2215
If we are cd'ing into a directory, and the directory has only one
child which is itself a directory, the autosuggestion should
descend as far as it can.
Fixes#2531
Previously 'set -ql' would only look for variables in the
immediate local scope. This was not very useful. It's also
arguably surprising, since a 'set -l' in a function, followed
by a 'set -ql' in a child block, would fail. There was also no
way to check for a function-scoped variable, since omitting the
scope would also pull in global variables.
We could revisit this and introduce an explicit function scope.
Fixes#2502
New implementation of migration code within the history_t class will
copy the contents of the old fish_history found in the config directory
to its new location in the data directory. The old file is left intact.
This is done only in the event that a fish_history is not already found in
the data directory ($XDG_DATA_HOME/fish or ~/.local/share/fish).
The fish_history file is now located in the "data"
directory ($XDG_DATA_HOME/fish or ~/.local/share/fish),
accessible using the function `path_get_data`.
(This commit also cleans trailing whitespace in the source file.)
Add new functions path_get_data and path_create_data which parallel existing
functions path_get_config and path_create_data. The new functions refer to
XDG_DATA_HOME, if it is defined, or ./local/share if not.
Modify history_filename to use the new function path_get_data.
As a consequence, fish_history will now be located in XDG_DATA_HOME,
not XDG_CONFIG_HOME.
Note that these changes mirror what is already used in
fish-shell/share/tools/create_manpage_completions.py, which stores the
completions in XDG_DATA_HOME
This change matches recommendations in the xdg basedir spec at
http://standards.freedesktop.org/basedir-spec/basedir-spec-0.7.html
($XDG_DATA_HOME defines the base directory relative to which user specific data
files should be stored. If $XDG_DATA_HOME is either not set or empty, a default
equal to $HOME/.local/share should be used.)
It addresses suggestions from the following issues:
1. Don't put history in $XDG_CONFIG_HOME (closes#744)
https://github.com/fish-shell/fish-shell/issues/744
2. Fish is placing non-config files in $XDG_CONFIG_HOME #1257https://github.com/fish-shell/fish-shell/issues/1257
3. Move non-config data out of $XDG_CONFIG_HOME #1669https://github.com/fish-shell/fish-shell/issues/1669
This reverts commit a66d44054c4aae44c307b10bb10469b4565e5027 due to
https://github.com/fish-shell/fish-shell/issues/2406 - entering keypad
mode causes various terminals to send undocumented and highly variable
escapes for keys not specified in the terminfo specification.
Teach Xcode to run new script xcode_version_gen.sh before building
the fish_shell and fish_indent targets. The script generates file
fish-build-version.h for inclusion by fish_version.cpp.
Note that Xcode always runs the script because of the phony target
named force-fish-build-version.h, but fish-build-version.h is only
touched if the contents of FISH-BUILD-VERSION-FILE change.
Fixes#890
This change eliminates global variables like stdout_buffer. Instead we wrap up
the IO information into a new struct io_streams_t, and thread that through
every builtin. This makes the intent clearer, gives us a place to hang new IO
data, and eliminates the ugly global state management like builtin_push_io.
This adds the new builtin 'string' which supports various string
manipulation and matching algorithms, including PCRE based regular
expressions.
Fixes#2296

Previously, the process's inherited $TERM value would be used.
This prevented users from being able to set $TERM in their config.fish files.
To make matters worse, the error message would print the computed $TERM value,
giving the mistaken impression that it was being used.

Cygwin FIFOs do not support more than one reader, so avoid them on this
platform. An autoconf feature test would be helpful but is tricky to
write.
