bash_completion: do not use aliased hg if it sources a script (issue6308)
I have an alias that sources a script around hg. Mercurial's bash_completion
script tries to use this as its main hg binary. But sourcing a wrapper breaks
Bash's completion. So this patch disables using the alias as the hg binary if
it starts with "source ".
Alias resolution was introduced in rev 191ab08e7099 for users with
"alias hg='hg --some_opts'".
See https://www.mercurial-scm.org/repo/hg/rev/191ab08e7099
#require pygit2
Setup:
$ GIT_AUTHOR_NAME='test'; export GIT_AUTHOR_NAME
> GIT_AUTHOR_EMAIL='test@example.org'; export GIT_AUTHOR_EMAIL
> GIT_AUTHOR_DATE="2007-01-01 00:00:00 +0000"; export GIT_AUTHOR_DATE
> GIT_COMMITTER_NAME="$GIT_AUTHOR_NAME"; export GIT_COMMITTER_NAME
> GIT_COMMITTER_EMAIL="$GIT_AUTHOR_EMAIL"; export GIT_COMMITTER_EMAIL
> GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"; export GIT_COMMITTER_DATE
> count=10
> gitcommit() {
> GIT_AUTHOR_DATE="2007-01-01 00:00:$count +0000";
> GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"
> git commit "$@" >/dev/null 2>/dev/null || echo "git commit error"
> count=`expr $count + 1`
> }
Test auto-loading extension works:
$ mkdir nogit
$ cd nogit
$ mkdir .hg
$ echo git >> .hg/requires
$ hg status
abort: repository specified git format in .hg/requires but has no .git directory
[255]
$ git init
Initialized empty Git repository in $TESTTMP/nogit/.git/
This status invocation shows some hg gunk because we didn't use
`hg init --git`, which fixes up .git/info/exclude for us.
$ hg status
? .hg/cache/git-commits.sqlite
? .hg/cache/git-commits.sqlite-shm
? .hg/cache/git-commits.sqlite-wal
? .hg/requires
$ cd ..
Now globally enable extension for the rest of the test:
$ echo "[extensions]" >> $HGRCPATH
> echo "git=" >> $HGRCPATH
Make a new repo with git:
$ mkdir foo
$ cd foo
$ git init
Initialized empty Git repository in $TESTTMP/foo/.git/
Ignore the .hg directory within git:
$ echo .hg >> .git/info/exclude
$ echo alpha > alpha
$ git add alpha
$ gitcommit -am 'Add alpha'
$ echo beta > beta
$ git add beta
$ gitcommit -am 'Add beta'
$ echo gamma > gamma
$ git status
On branch master
Untracked files:
(use "git add <file>..." to include in what will be committed)
gamma
nothing added to commit but untracked files present (use "git add" to track)
Without creating the .hg, hg status fails:
$ hg status
abort: no repository found in '$TESTTMP/foo' (.hg not found)!
[255]
But if you run hg init --git, it works:
$ hg init --git
$ hg id --traceback
3d9be8deba43 tip master
$ hg status
? gamma
Log works too:
$ hg log
changeset: 1:3d9be8deba43
bookmark: master
tag: tip
user: test <test@example.org>
date: Mon Jan 01 00:00:11 2007 +0000

summary: Add alpha
and bookmarks:
$ hg bookmarks
* master 1:3d9be8deba43
diff even works transparently in both systems:
$ echo blah >> alpha
$ git diff
diff --git a/alpha b/alpha
index 4a58007..faed1b7 100644
--- a/alpha
+++ b/alpha

$ hg diff --git

Remove a file, it shows as such:
$ rm alpha
$ hg status
! alpha
? gamma
Revert works:
$ hg revert alpha --traceback
$ hg status
? gamma
$ git status
On branch master
Untracked files:
(use "git add <file>..." to include in what will be committed)
gamma
nothing added to commit but untracked files present (use "git add" to track)
Add shows sanely in both:
$ hg add gamma
$ hg status

$ hg files
alpha
beta
gamma
$ git ls-files
alpha
beta
gamma
$ git status
On branch master
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
new file: gamma
forget does what it should as well:
$ hg forget gamma
$ hg status
? gamma
$ git status
On branch master
Untracked files:
(use "git add <file>..." to include in what will be committed)
gamma
nothing added to commit but untracked files present (use "git add" to track)
clean up untracked file
$ rm gamma
hg log FILE
$ echo a >> alpha
$ hg ci -m 'more alpha' --traceback --date '1583522787 18000'
$ echo b >> beta
