It's actually unavailable in the minimal chroots Debian builds our
package on. That's allowed by POSIX, which specifies ps(1) to be
optional, whereas id(1) —
- is not optional in POSIX
- should exist on every system anyone might run the testsuite on
- has the same length name, so test expectations don't have to be updated
- doesn't take a filename argument (ditto)
That does make the pipeline as a whole somewhat nonsensical
semantically, but it remains just as valid syntactically.
Args for proxychains should be f:q => -f file : -q quiet.
From comments in the same function:
# $precommand_options maps precommand name to values of $flags_with_argument,
# $flags_sans_argument, and flags_solo for that precommand, joined by a
# colon.
5.8.0.3 was correct until 5.8.1 was released (see the great-grandparent of this
commit, "driver: Bump the in-development is-at-least checks so they return
false on zsh 5.8.1, released yesterday").
5.2 -> 5.3 is simply a typo fix. zle-line-pre-redraw has been available since then.
PR #776 fixed an issue with complex aliases and expansion. However, this change
also introduced a problem with aliases which contain `]` (for example, commonly
seen on macOS: `alias ]=open`), due to using an associative array `seen_alias`,
indexed by the alias name. Due to `"$seen_alias[$arg]"`, it would fail when
`$arg` is expanded to anything containing `]`'. Thus, typing `] /` would result
in:
```
> ] /
(anon):unset:3: seen_alias[]]: invalid parameter name
```
This change fixes the issue by ensuring we properly access keys in the
associative array `seen_alias`.
Older versions of zsh have issues with map keys having special
characters, especially lacking ways to remove such keys. The
issue is described in detail in
https://unix.stackexchange.com/questions/626393/in-zsh-how-do-i-unset-an-arbitrary-associative-array-element.
This fix uses proposal from
[zsh-workers/43269](https://www.zsh.org/mla/workers/2018/msg01073.html),
discovered by Stephane Chazelas, that boils down to avoid removing keys
from the map, and reconstruct the map anew with some keys omitted.
