Enable push notification on Mercurial repository

Saturday Apr 28, 2007

OS: Solaris Nevada (build 59, sparc)
Mercurial: 0.9.3

Due to the lack of 'diffstat' tool on Solaris, the notification extension (hgext.notify) doesn't work well on Solaris. After several trying, I finally made it work.

Here is the setup steps:

1. vi .hg/hgrc
   
   [web]
   contact = {your name}
   description = Docking Workspace for Solaris WOS, SunSolve (Patch) and JES
   style = gitweb
   allow_archive = gz zip bz2
   
   [extensions]
   hgext.patchbomb =
   hgext.notify =
   
   [hooks]
   # send one email per change
   #incoming.notify = python:hgext.notify.hook
   # send one email per group of changes
   changegroup.notify = python:hgext.notify.hook
   
   [email]
   from = svnroot@agc163.prc.sun.com
   method = /usr/sbin/sendmail
   
   [web]
   baseurl = http://agc163.prc.sun.com/hg/
   
   [notify]
   # multiple sources can be specified as a whitespace separated list
   sources = serve push pull bundle
   # set this to False when you're ready for mail to start sending
   test = false
   config =
   # repos live in /workspace/scm/hg/hgroot on server, so strip 5 "/" chars
   strip = 5
   
   # you can override the changeset template here, if you want.
   # If it doesn't start with \n it may confuse the email parser.
   # here's an example that makes the changeset template look more like hg log:
   template = \ndetails:   {baseurl}{webroot}/rev/{node|short}\nchangeset: {rev}:{node|short}\nuser:      {author}\ndate:      {date|date}\ndescription:\n{desc}\n
   
   [reposubs]
   # key is glob pattern, value is comma-separated list of subscriber emails
   * = {email address}
   
   
2. When tried to push back, it failed
   
   [gbuild@agc141 s11]$ hg push
   Enter passphrase for key '/export/home/gbuild/.ssh/id_dsa':
   pushing to ssh://hgroot@agc163.prc.sun.com/docking

   remote: adding changesets
   remote: adding manifests
   remote: adding file changes
   remote: added 1 changesets with 76 changes to 76 files
   remote: /bin/sh: diffstat: not found
   remote: error: changegroup.notify hook raised an exception: [Errno 32] Broken pipe
   [gbuild@agc141 s11]$
   
   
3. After searching on Internet, I found the patch for Solaris
   
   http://www.selenic.com/mercurial/bts/file270/diffstat.patch
   
   

   diff -r 730cbd26552c -r 79639a44dd23 mercurial/patch.py

   @@ -635,6 +635,8 @@ def export(repo, revs, template='hg-%h.p
            single(rev, seqno+1, fp)
    
    def diffstat(patchlines):
   +    if not util.find_in_path('diffstat', os.environ.get('PATH', '')):
   +        return
        fd, name = tempfile.mkstemp(prefix="hg-patchbomb-", suffix=".txt")
        try:
            p = popen2.Popen3('diffstat -p1 -w79 2>/dev/null > ' + name)

4. But it still failed when push back
   
   [gbuild@agc141 s10u3]$ hg --traceback push
   Enter passphrase for key '/export/home/gbuild/.ssh/id_dsa':

5. After rename /usr/lib/python2.4/vendor-packages/mercurial/patch.pyc, the error still existed.
6. I finally found following patch after several trying:
