#!/usr/bin/python # # Interactive script for sending a collection of Mercurial changesets # as a series of patch emails. # # The series is started off with a "[PATCH 0 of N]" introduction, # which describes the series as a whole. # # Each patch email has a Subject line of "[PATCH M of N] ...", using # the first line of the changeset description as the subject text. # The message contains two or three body parts: # # The remainder of the changeset description. # # If the diffstat program is installed, the result of running # diffstat on the patch. # # The patch itself, as generated by "hg export". # # Each message refers to all of its predecessors using the In-Reply-To # and References headers, so they will show up as a sequence in # threaded mail and news readers, and in mail archives. # # For each changeset, you will be prompted with a diffstat summary and # the changeset summary, so you can be sure you are sending the right # changes. # # It is best to run this script with the "-n" (test only) flag before # firing it up "for real", in which case it will display each of the # messages that it would send. # # To configure a default mail host, add a section like this to your # hgrc file: # # [smtp] # host = my_mail_host # port = 1025 from email.MIMEMultipart import MIMEMultipart from email.MIMEText import MIMEText from mercurial import commands from mercurial import fancyopts from mercurial import hg from mercurial import ui import os import popen2 import readline import smtplib import socket import sys import tempfile import time def diffstat(patch): fd, name = tempfile.mkstemp() try: p = popen2.Popen3('diffstat -p1 -w79 2>/dev/null > ' + name) try: for line in patch: print >> p.tochild, line p.tochild.close() if p.wait(): return fp = os.fdopen(fd, 'r') stat = [] for line in fp: stat.append(line.lstrip()) last = stat.pop() stat.insert(0, last) stat = ''.join(stat) if stat.startswith('0 files'): raise ValueError return stat except: raise finally: try: os.unlink(name) except: pass def patchbomb(ui, repo, *revs, **opts): def prompt(prompt, default = None, rest = ': ', empty_ok = False): try: if default: prompt += ' [%s]' % default prompt += rest r = raw_input(prompt) if not r and not empty_ok: raise EOFError return r except EOFError: if default is None: raise return default def confirm(s): if not prompt(s, default = 'y', rest = '?
