reverse sense of return value from python hooks. old scheme (False/None/0/'' == fail) made coding style unnatural, did not allow use of mercurial commands as hooks. new scheme (False/None/0 == pass) is pythonic, does not require peculiar "return True" at ends of hooks, allows hooks like this: [hooks] # update working dir after push into this repo changegroup.update = python:mercurial.commands.update

#!/bin/sh

mkdir test
cd test
echo foo>foo
hg init
hg addremove
hg commit -m 1
hg verify
hg serve -p 20059 -d --pid-file=hg.pid
cd ..

http_proxy= hg clone http://localhost:20059/ copy
cd copy
hg verify
hg co
cat foo
hg manifest
hg pull

kill `cat ../test/hg.pid`
