# Command 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. # # [Optional] 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 use your pager to # display each of the messages that it would send. # # The "-m" (mbox) option will create an mbox file instead of sending # the messages directly. This can be reviewed e.g. with "mutt -R -f mbox", # and finally sent with "formail -s sendmail -bm -t < mbox". # # To configure a default mail host, add a section like this to your # hgrc file: # # [smtp] # host = my_mail_host # port = 1025 # tls = yes # or omit if not needed # username = user # if SMTP authentication required # password = password # if SMTP authentication required - PLAINTEXT # # To configure other defaults, add a section like this to your hgrc # file: # # [patchbomb] # from = My Name <my@email> # to = recipient1, recipient2, ... # cc = cc1, cc2, ... from mercurial.demandload import * demandload(globals(), '''email.MIMEMultipart email.MIMEText email.Utils mercurial:commands,hg,ui os errno popen2 smtplib socket sys tempfile time''') from mercurial.i18n import gettext as _ try: # readline gives raw_input editing capabilities, but is not # present on windows import readline except ImportError: pass def diffstat(patch): fd, name = tempfile.mkstemp(prefix="hg-patchbomb-", suffix=".txt") 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): '''send changesets as a series of patch emails The series starts with a "[PATCH 0 of N]" introduction, which describes the series as a whole.
