          Priority: normal
            Bug ID: 3735
                CC: mercurial-devel at selenic.com, natosha at gmail.com
          Assignee: bugzilla at selenic.com
           Summary: update to old revision with subrepository with
                    largefiles escapes with exception
          Severity: bug
    Classification: Unclassified
                OS: Windows
          Reporter: Bastian.Wassermann at multivac.de
          Hardware: PC
            Status: UNCONFIRMED
           Version: unspecified
         Component: largefiles
           Product: Mercurial

When i try to update my main-repository (without subs any more) to an old
revision with subs that have largefiles enabled, it appears the exception and
the end of this description.

That exception only appears, if i enter a different default-push server to the
hgrc file. if there is no default-push server entered, the update works fine.
That is strange behavior for me, because, while update there should bo no
communication to default-push server (in my opinion). 
I tried to debug the method calls, because i want to contibute to mercurial
community with bugfixes, by mythelf, but i found no suitable way to get prints
in tortoise console to debug the method calls. Maybe someone can give me a
hint, how to write debug notes to tortoise console. 

How far i stepped into the exception, i identified the method
lfutil.findfile(repo, hash) to be wrong.

I tried debug messages like this:
#     print ('findfile: %s - %s\n') % (hash, repo) 
#     raise util.Abort(_('findfile: %s - %s\n') % (hash, repo))
#     repo.ui.status(_('new message\n'))
#     repo.ui.note(_('new message\n'))

With the raise util.Abort code i got the print:
Abort: findfile: 4 - <hgext.largefiles.reposetup.lfilesrepo object at
0x00C29BD0>

And that lookes wired, because the hash has only one digit.

Exception message in tortoisehg:
'http://muwo-st/hg/IPC_neu_push/' does not appear to be an hg repository:
