Summary: Translate alias like `echo = !echo foo` to `echo = debugrunshell '--cmd=echo foo'`. This enables the Rust shell alias handling code path. The Python shell alias handling was removed. The majority part of `test-alias.t` still passes. That includes some "weird" shell alias features. This has some test changes, through: - `$HG_ARGS` is no longer supported. And tests depending on it are changed. `$@` will be the alternative for most cases. Practically, our `$HG_ARGS` users seem to come from https://stackoverflow.com/a/833387, which does not seem to use `$HG_ARGS` correctly (since `$HG_ARGS` includes the command name). - Early-parse commands (ex. `hg log -b '--config=alias.log=!echo howdy'`) no longer works. - The warning `--repository ignored` now shows up, since `debugrunshell` is a "no-repo" command. - Global flags can no longer be used after shell aliases. Supporting them is a head-ache. - `circular alias` error message changed because it's now reported by the Rust code, which does not report all alias names right now.

"--" may be an option value:
|
|
|
|
$ hg -R -- log
|
|
abort: repository -- not found!
|
|
[255]
|

$ hg log -R --

$ hg log -T --

-- (no-eol)
|
|
$ hg log -T -- -k nomatch

Parsing of early options should stop at "--":
|
|
|
|
$ hg cat -- --config=hooks.pre-cat=false
|
|
--config=hooks.pre-cat=false: no such file in rev cb9a9f314b8b

Unparsable form of early options:
|
|
|
|
$ hg cat --debugg
|
|
abort: option --debugger may not be abbreviated!
|

[255]
|
|
|
|
Parsing failure of early options should be detected before executing the
|
|
command:
|
|
|
|
$ hg log -b '--config=hooks.pre-log=false' default
|
|
abort: option --config may not be abbreviated!
|
|
[255]
|
|
$ hg log -b -R. default
|
|
abort: option -R has to be separated from other options (e.g. not -qR) and --repository may only be abbreviated as --repo!
|
|
[255]
|
|
$ hg log --cwd .. -b --cwd=. default
|
|
abort: option --cwd may not be abbreviated!
|
|

However, we can't prevent it from loading extensions and configs:
|
|
|
|
$ cat <<EOF > bad.py
|
|
> raise Exception('bad')
|
|
> EOF
|
|
$ hg log -b '--config=extensions.bad=bad.py' default
|
|
*** failed to import extension bad from bad.py: bad

abort: option --config may not be abbreviated!

Early options can't be specified in [aliases] and [defaults] because they are
|
|
applied before the command name is resolved:
|
|
|
|
$ hg log -b '--config=alias.log=log --config=hooks.pre-log=false'
|
|
hg log: option -b not recognized
|
|
(use 'hg log -h' to get help)
|
|
[255]
|
|
|
|
$ hg log -b '--config=defaults.log=--config=hooks.pre-log=false'
|
|
abort: option --config may not be abbreviated!
|
|
[255]
|
|
|
|
XXX: Should we support this?
|
|
Shell aliases bypass any command parsing rules but for the early one:
|
|
|
|
$ hg log -b '--config=alias.log=!echo howdy'
|
|
abort: option --config may not be abbreviated!

For compatibility reasons, HGPLAIN=+strictflags is not enabled by plain HGPLAIN:

$ mkdir $TESTTMP/repo1

$ cd $TESTTMP/repo1

$ rm -rf $TESTTMP/repo1

The output could be one of the following and something else:
|
|
chg: abort: failed to getcwd (errno = *) (glob)
|
|
abort: error getting current working directory: * (glob)
|
|
sh: 0: getcwd() failed: $ENOENT$
|
|
Since the exact behavior depends on the shell, only check it returns non-zero.
