precommit mercurial hook, чтобы остановить фиксацию на неправильной ветке

Да, вы точно знаете, что precommit хук может это сделать. Если вы хотите сделать это в bash, вы можете использовать что-то вроде:

#!/bin/bash
revs=$(hg log -r "$HG_NODE:tip" --template '{rev} ') #Intentional space after {rev}
rc=0
for rev in $revs
do
    files=$(hg log -r $rev --template '{files}')
    #Above will include discards. So you cannot 'hg cat' them all. So you may want
    #  files=$(hg log -r $rev --template '{file_mods} {file_adds}')
    branch=$(hg log -r $rev --template '{branch}')
    for file in $files
    do
        if [ branch == "debian" ] &&  [ "$(echo $file | grep -v "debian")" != "" ] ; then
          echo "ERROR: Non debian file in debian branch."
          exit 1
        fi
        if [ branch != "debian" ] &&  [ "$(echo $file | grep "debian")" != "" ] ; then
          echo "ERROR: debian file in non-debian branch."
          exit 1
        fi
    done
done
exit $rc

Эти строки if / grep почти наверняка неверны, но вы понимаете.

Используя решение @ry4an в качестве отправной точки, я придумал следующий скрипт с использованием нового hglib API.

#!/usr/bin/python                                                                                                                                                         

# Abort commit to the debian branch if it is not contained in a debian                                                                                                    
# subdirectory                                                                                                                                                            

# Similary abort commit to non-debian branches if it is contained in a                                                                                                    
# debian subdirectory                                                                                                                                                     

import hglib, os, sys
client = hglib.open("/home/faheem/hooktest")
ctx = client['tip']
files = ctx.files()  
branch = ctx.branch()

for f in files:
    d = os.path.dirname(f)
    if branch == "debian" and d != "debian":
        sys.exit("cannot commit %s (file not in 'debian' directory) to 'debian' branch"%f)
    if branch != "debian" and d == "debian":
        sys.exit("cannot commit %s (file in 'debian' directory) to non 'debian' branch"%f)

В следующем коде используется метод, использующий внутрипроцессные перехватчики. Эти функции можно использовать в .hgrc репозитория Mercurial следующим образом.

pretxncommit.foo = python:mercurial_hooks.abort_commit_to_wrong_branch
pre-qfinish.bar = python:mercurial_hooks.qfinish_abort_commit_to_wrong_branch

abort_commit_to_wrong_branch запрещает нормальные фиксации в неправильную ветвь, но разрешает фиксации MQ. qfinish_abort_commit_to_wrong_branch не позволяет qfinish преобразовывать коммиты MQ на неправильной ветке в обычные коммиты.

Я использовал функцию finish в https://bitbucket.org/mirror/mercurial/src/tip/hgext/mq.py?at=default#cl-3034 для справки.
