extend network protocol to stop clients from locking servers
now all repositories have capabilities slot, tuple with list of names.
if 'unbundle' capability present, repo supports push where client does
not need to lock server. repository classes that have unbundle capability
also have unbundle method.
implemented for ssh now, will be base for push over http.
unbundle protocol acts this way. server tells client what heads it
has during normal negotiate step. client starts unbundle by repeat
server's heads back to it. if server has new heads, abort immediately.
otherwise, transfer changes to server. once data transferred, server
locks and checks heads again. if heads same, changes can be added.
else someone else added heads, and server aborts.
if client wants to force server to add heads, sends special heads list of
'force'.

# 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 other defaults, add a section like this to your hgrc # file: # # [email] # 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 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.
