These macros were historically used only in internal error messages which
should never happen! Now we are able to enforce they never happen at
compile time so we can remove them.
No functional change here.

When you do
```fish
set foo-bar baz
```
"foo-baz" isn't usable as a variable *name*. When you just say the
"variable" is invalid that could also be interpreted to be a special
type of variable or something.
This conditionally set a function variable in an unsafe way.
If you do something like
```fish
if condition
set -f foo bar
end
```
then, if the condition was false, $foo could still use a global variable.
In this case, alias would now fail if a variable $wraps was defined globally.
This reverts most of commit 14458682d9.
The message rewording can stay, it's *fine* (tho it'll break the
translations but then we'd need a real string freeze with a
translation team for those to be worth anything anyway, soo)

String tokens are subdivided by command substitutions. Some syntax errors
can occur in the gap between two command substitutions. Make the caret point
to the start of that gap, instead of the token start.
When expanding command substitutions, we use a naïve way of detecting whether
the cmdsub has the optional leading dollar. We check if the last character was
a dollar, which breaks if it's an escaped dollar. We wrongly expand
\$(echo "") to the empty string. Fix this by checking if the dollar was escaped.
The parse_util_* functions have a bunch of output parameters. We should
return a parameter bag instead (I think I tried once and failed).
Given
set var a
echo "$var$(echo b)"
the double-quoted string is expanded right-to-left, so we construct an
intermediate "$varb". Since the variable "varb" is undefined, this wrongly
expands to the empty string (should be "ab"). Fix this by isolating the
expanded command substitution internally. We do the same when handling
unquoted command substitutions.
Fixes#8849
Static destructors cause the destructor for a global object to run when
the program exits. They are bad because:
1. Registering them takes time and memory at startup
2. Running them takes time at shutdown and also they may have weird
interactions.
This shaves about 12k off of the binary size.
Unfortunately gcc does not support this flag.
The read test is now failing on GitHub actions even though it passes on
my Mac. It may be due to differences in dd between these two
environments. Stop using dd and just use head.
The read.fish check has a test where it limits the amount of data passed to
`read` to 8192 bytes, and verifies that fish reads exactly that amount.
This check occasionally fails on the OBS builds; it's very hard to repro a
failure locally, but I finally did it.
The amount of data written is limited via `yes` and `dd`:
yes $line | dd bs=1024 count=(math "$fish_read_limit / 1024")
The bug is that `dd` outputs a fixed number of "blocks" where a block
corresponds to a single read. As `yes` and `dd` are running concurrently,
it may happen that `dd` performs a short read; this then counts as a single
block. So `dd` may output less than the desired amount of data.
This can be verified by removing the 2>/dev/null redirection; on a
successful run dd reports `8+0 records out`, on a failed run it reports
`7+1 records out` because one of the records was short.
Fix this by using `fullblock` so that dd will no longer count a short read
as a single block. `head` would probably be a simpler tool to use but we'll
do this for now.
Happily it's not a fish bug. No need to relnote it.
1. Bravely use a real enum for has_arg, despite the warnings.
2. Use some C++11 initializers so we don't have to pass an int for this
parameter.
No functional change expected here.
git.fish loads git-foo.fish completions.
As reported in #8831, this can be slow when the user has run something like
complete git-foo -w 'git diff'
because git.fish runs 'complete -C "git-autofixup "' at load time.
Commit 09161761c (Complete custom "git-foo" commands from "git foo",
2021-01-24) did that to avoid adding filename completions for "git foo".
Drop that check.
This means that users who don't want filename completion for "git foo",
need to define at least one custom completion for "git-foo", like
complete git-foo -f
If the history file is larger than 4GB on a 32 bit system, fish will
refuse to read it. However the check was incorrect because it cast the
file size to size_t, which may be 32 bit. Switch to using uint64.
fd_monitor is used when an external command pipes into a buffer, e.g. for
command substitutions. It monitors the read end of the external command's
pipe in the background, and fills the buffer as data arrives. fd_monitor is
multiplexed, so multiple buffers can be monitored at once by a single
thread.
It may happen that there's no active buffer fill; in this case fd_monitor
wants to keep its thread alive for a little bit in case a new one arrives.
This is useful for e.g. handling loops where you run the same command
multiple times.
However there was a bug due to a refactoring which caused fd_monitor to
exit too aggressively. This didn't affect correctness but it meant more
thread creation and teardown.
Fix this; this improves the aliases.fish benchmark by about 20 msec.
No need to changelog this IMO.
This was already apparently supposed to work, but didn't because we
just overrode errno again.
This now means that, if a correctly named candidate exists, we don't
start the command-not-found handler.
