Summary: The postincoming checks prints out advice of the following forms: * `(run 'hg heads' to see heads)` * `(run 'hg heads' to see heads, 'hg merge' to merge)` * `(run 'hg heads .' to see heads, 'hg merge' to merge)` * `(run 'hg update' to get a working copy)` This advice is no longer useful, so remove it.

# Basics
|
|
|
|
If the script doesn't return anything, an abort is raised:
|
|
$ printf "#!/bin/bash\n" > stable.sh
|
|
$ chmod +x stable.sh
|
|
$ setconfig stablerev.script=./stable.sh
|
|
$ hg log -r "getstablerev()"
|
|
abort: stable rev returned by script (./stable.sh) was empty
|
|
[255]
|
|
|
|
Make the script return something:
|
|
$ printf "#!/bin/bash\n\necho 'B'" > stable.sh
|
|
$ hg log -r "getstablerev()"
|
|
[112478962961]: B
|
|
|
|
Change the script, change the result:
|
|
$ printf "#!/bin/bash\n\necho 'C'" > stable.sh
|
|
$ hg log -r "getstablerev()"
|
|
[26805aba1e60]: C
|
|
|
|
The script is always run relative to repo root:
|
|
$ mkdir subdir
|
|
$ cd subdir
|
|
$ hg log -r "getstablerev()"
|
|
[26805aba1e60]: C
|
|
$ cd ..
|
|
|
|
JSON is also supported:
|
|
$ printf "#!/bin/bash\n\necho '{\"node\": \"D\"}'" > stable.sh
|
|
$ hg log -r "getstablerev()"
|
|
[f585351a92f8]: D
|
|
|
|
Invalid JSON aborts:
|
|
$ printf "#!/bin/bash\n\necho '{node\": \"D\"}'" > stable.sh
|
|
$ hg log -r "getstablerev()"
|
|
abort: stable rev returned by script (./stable.sh) was invalid
|
|
[255]
|
|
|
|
An alias can be used for simplicity:
|
|
$ printf "#!/bin/bash\n\necho 'A'" > stable.sh
|
|
$ setconfig revsetalias.stable="getstablerev()"
|
|
$ hg log -r stable
|
|
[426bada5c675]: A
|
|
|
|
# Auto-pull
|
|
|
|
Make another repo with "E" (9bc730a19041):
|
|
$ cd ..
|
|
$ newrepo
|
|
$ hg debugdrawdag <<'EOS'
|
|
> E
|
|
> |
|
|
> D
|
|
> |
|
|
> C
|
|
> |
|
|
> B
|
|
> |
|
|
> A
|
|
> EOS
|
|
$ cd ../repo1
|
|
|
|
What if the stable commit isn't present locally?
|
|
$ printf "#!/bin/bash\n\necho '9bc730a19041'" > stable.sh
|
|
$ hg log -r stable
|
|
abort: stable commit (9bc730a19041) not in the repo
|
|
(try hg pull first)
|
|
[255]
|
|
|
|
The revset can be configured to automatically pull in this case:
|
|
$ setconfig paths.default=../repo2
|
|
$ setconfig stablerev.pullonmissing=True
|
|
$ hg log -r stable
|
|
stable commit (9bc730a19041) not in repo; pulling to get it...
|
|
pulling from $TESTTMP/repo2
|
|
searching for changes
|
|
adding changesets
|
|
adding manifests
|
|
adding file changes
|
|
added 1 changesets with 1 changes to 1 files
|
|
new changesets 9bc730a19041
|
|
[9bc730a19041]: E
|
|
|
|
But it might not exist even after pulling:
|
|
$ printf "#!/bin/bash\n\necho 'abcdef123'" > stable.sh
|
|
$ hg log -r stable
|
|
stable commit (abcdef123) not in repo; pulling to get it...
|
|
pulling from $TESTTMP/repo2
|
|
searching for changes
|
|
no changes found
|
|
abort: stable commit (abcdef123) not in the repo
|
|
(try hg pull first)
|
|
[255]
|
|
|
|
# Targets
|
|
|
|
Targets are disabled by default:
|
|
$ hg log -r "getstablerev(foo)"
|
|
abort: targets are not supported in this repo
|
|
[255]
|
|
|
|
But they can be made optional or required:
|
|
$ setconfig stablerev.targetarg=optional
|
|
$ hg log -r "getstablerev(foo)"
|
|
stable commit (abcdef123) not in repo; pulling to get it...
|
|
pulling from $TESTTMP/repo2
|
|
searching for changes
|
|
no changes found
|
|
abort: stable commit (abcdef123) not in the repo
|
|
(try hg pull first)
|
|
[255]
|
|
|
|
$ setconfig stablerev.targetarg=required
|
|
$ hg log -r "getstablerev()"
|
|
abort: must pass a target
|
|
[255]
|
|
|
|
Try making the script return different locations, based on the target:
|
|
$ cat <<'EOF' > stable.sh
|
|
> #!/bin/bash
|
|
> # The script is passed "--target <TARGET>", so look at $2:
|
|
> if [ "$2" = "foo" ]; then
|
|
> echo 'D'
|
|
> else
|
|
> echo 'C'
|
|
> fi
|
|
> EOF
|
|
$ hg log -r "getstablerev(foo)"
|
|
[f585351a92f8]: D
|
|
$ hg log -r "getstablerev(bar)"
|
|
[26805aba1e60]: C
|
|
|
|
Lastly, targets can be used in conjunction with aliases:
|
|
|
|
$ setconfig revsetalias.stable="getstablerev(foo)"
|
|
$ hg log -r stable
|
|
[f585351a92f8]: D
