'''sending 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. To enable this extension: [extensions] hgext.patchbomb = To configure other defaults, add a section like this to your hgrc file: [email] from = My Name <my@email> to = recipient1, recipient2, ... cc = cc1, cc2, ... bcc = bcc1, bcc2, ... Then you can use the "hg email" command to mail a series of changesets as a patchbomb. To avoid sending patches prematurely, it is a good idea to first run the "email" command with the "-n" option (test only). You will be prompted for an email recipient address, a subject an an introductory message describing the patches of your patchbomb. Then when all is done, patchbomb messages are displayed. If PAGER environment variable is set, your pager will be fired up once for each patchbomb message, so you can verify everything is alright. The "-m" (mbox) option is also very useful. Instead of previewing each patchbomb message in a pager or sending the messages directly, it will create a UNIX mailbox file with the patch emails. This mailbox file can be previewed with any mail user agent which supports UNIX mbox files, i.e. with mutt: % mutt -R -f mbox When you are previewing the patchbomb messages, you can use `formail' (a utility that is commonly installed as part of the procmail package), to send each message out: % formail -s sendmail -bm -t < mbox That should be all. Now your patchbomb is on its way out.''' import os, errno, socket, tempfile, cStringIO import email.MIMEMultipart, email.MIMEBase import email.Utils, email.Encoders, email.Generator from mercurial import cmdutil, commands, hg, mail, patch, util from mercurial.i18n import _ from mercurial.node import bin def patchbomb(ui, repo, *revs, **opts): '''send changesets by email By default, diffs are sent in the format generated by hg export, one per message. The series starts 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. First, the rest of the changeset description. Next, (optionally) if the diffstat program is installed, the result of running diffstat on the patch. Finally, the patch itself, as generated by "hg export". With --outgoing, emails will be generated for patches not found in the destination repository (or only those which are ancestors of the specified revisions if any are provided) With --bundle, changesets are selected as for --outgoing, but a single email containing a binary Mercurial bundle as an attachment will be sent. Examples: hg email -r 3000 # send patch 3000 only hg email -r 3000 -r 3001 # send patches 3000 and 3001 hg email -r 3000:3005 # send patches 3000 through 3005 hg email 3000 # send patch 3000 (deprecated) hg email -o # send all patches not in default hg email -o DEST # send all patches not in DEST hg email -o -r 3000 # send all ancestors of 3000 not in default hg email -o -r 3000 DEST # send all ancestors of 3000 not in DEST hg email -b # send bundle of all patches not in default hg email -b DEST # send bundle of all patches not in DEST hg email -b -r 3000 # bundle of all ancestors of 3000 not in default hg email -b -r 3000 DEST # bundle of all ancestors of 3000 not in DEST Before using this command, you will need to enable email in your hgrc. See the [email] section in hgrc(5) for details.
