Missing parameter for early option:

$ hg log -R 2>&1 | grep 'hg log'

hg log: option -R requires argument
|

(use 'hg log -h' to show more help)

$ hg log -R -- 2>&1 | grep 'hg log'

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
|
|
|

|
|
|
$ hg cat -- --debugger

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!
|
|
|
[255]
|
|
|
|
|
|
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!
|
|
|

|
|
|
|
|
|
$ mkdir -p badrepo/.hg
|
|
|
$ echo 'invalid-syntax' > badrepo/.hg/hgrc
|
|
|
$ hg log -b -Rbadrepo default
|
|
|
hg: parse error at badrepo/.hg/hgrc:1: invalid-syntax
|
|
|
[255]
|
|
|
|
|
|
$ hg log -b --cwd=inexistent default
|
|
|
abort: No such file or directory: 'inexistent'
|
|
|
[255]
|
|
|
|
|
|
$ hg log -b '--config=ui.traceback=yes' 2>&1 | grep '^Traceback'
|
|
|
Traceback (most recent call last):
|
|
|
$ hg log -b '--config=profiling.enabled=yes' 2>&1 | grep -i sample
|
|
|
Sample count: .*|No samples recorded\. (re)
|

|
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
|
|
|
error in definition for alias 'log': --config may only be given on the command
|
|
|
line
|
|
|
[255]
|
|
|
|
|
|
$ hg log -b '--config=defaults.log=--config=hooks.pre-log=false'
|
|
|
abort: option --config may not be abbreviated!
|
|
|
[255]
|
|
|
|
|
|
Shell aliases bypass any command parsing rules but for the early one:
|
|
|
|
|
|
$ hg log -b '--config=alias.log=!echo howdy'
|
|
|
howdy
|
|
|
|
|
|
[defaults]
|
|
|
|
|
|
$ hg cat a
|
|
|
a
|
|
|
$ cat >> $HGRCPATH <<EOF
|
|
|
> [defaults]
|
|
|
> cat = -r null
|
|
|
> EOF
|
|
|
$ hg cat a
|
|
|
a: no such file in rev 000000000000
|
|

|
|
|
|
|
|
$ cd "$TESTTMP"
|
|
|
|
|
|
OSError "No such file or directory" / "The system cannot find the path
|
|
|

|
|
|
|

|
$ hg -R a archive ''
|
|
|
abort: *: '' (glob)
|
|
|
[255]
|
|
|
|
|
|
#if no-outer-repo
|
|
|
|
|
|
No repo:
|
|
|
|
|
|
$ hg cat
|
|
|
abort: no repository found in '$TESTTMP' (.hg not found)!
|

#endif

#if rmcwd
|

Current directory removed:
|
|
|
|
|
|
$ 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: No such file or directory
|
|
|
Since the exact behavior depends on the shell, only check it returns non-zero.
