highlight.cpp was blindly calling path_get_path for each head command
typed at the prompt which triggers a lot of syscalls via waccess.
It's still going to do that while commands are being composed, but now
it won't if we can make a cheap lookup to the builtins/functions hash
table and can determine that it's a valid command before inspecting the
filesystem.
When fish receives a "cancellation inducing" signal (SIGINT in particular)
it has to unwind execution - for example while loops or whatever else that
is executing. There are two ways this may come about:
1. The fish process received the signal
2. A child process received the signal
An example of the second case is:
some_command | some_function
Here `some_command` is the tty owner and so will receive control-C, but
then fish has to cancel function execution.
Prior to this change, these were handled uniformly: both would just set a
cancellation signal inside the parser. However in the future we will have
multiple parsers and it may not be obvious which one to set the flag in.
So instead distinguish these cases: if a process receives SIGINT we mark
the signal in its job group, and if fish receives it we set a global
variable.
The colors defined in `colorutils.js` are specified in
fish format, and therefore RGB values lack the leading
`#` character and do not fully follow the html/css spec
(w3.org/TR/css-color-4/#typedef-hex-color).
Web config sends these values as-is to the browser,
without first converting to a browser-friendly format.
While this (somehow) works for the most part, a few
colors get lost along the way and do not display in
the customization selector nor in the preview when
selected. This behavior was seen in Firefox.
To fix this, let's prepend the missing '#' character
to all RGB colors defined in `colorutils.js`.
This improves some generated completions, for example:
diff -u completions.old/g3topbm.fish completions.new/g3topbm.fish
+complete -c g3topbm -o stop_error -d 'This option tells g3topbm to fail when it finds a problem in the input'
-complete -c g3topbm -o stop_error
When CMake's own curses logic fails to find curses/ncurses, we fall back to
pkg-config and manually link the required libraries. Some platforms (RHEL 6,
see #6587) require CURSES_EXTRA_LIBRARY=tinfo, so we link against libtinfo
if it's found but are happy to continue without it if it doesn't exist.
Closes#6587
This adopts the Contributor Covenant Code of Conduct 2.0
We don't currently have an email address for enforcement, once that's set up we can
add it in.

This used to use "success", which was our own thing, but which I can't
get working.
So instead we just use ".then", which only passes one object as an
argument that then contains all the other data we use.
This should be enough to complete the port to angular 1.8
We were previously aborting the main event loop before calling fish_exit
in the event of a SIGHUP. This patch causes the SIGHUP to be stored in a
separate state variable from a regular "must exit" condition so the
associated event can be fired before we terminate the loop.
All streams are redirected before the event is called to prevent a
SIGTTIN/SIGTTOU due to the user script reading/writing from a disposed
tty.
Closes#7014
