Bug ID: 5719
Summary: ctrl-c during `hg push` managed to leave abandoned
transaction on a remote repo (possibly bitbucket
specific)
Product: Mercurial
Version: default branch
Hardware: PC
OS: Linux
Status: UNCONFIRMED
Severity: feature
Priority: wish
Component: Mercurial
Assignee: bugzi...@mercurial-scm.org
Reporter: h...@pewpew.net
CC: mercurial-devel@mercurial-scm.org
Note: this is possibly bitbucket specific, I have not attempted to reproduce.
TL;DR: I tried to `hg push -f`, realized I wanted to `hg push -f -r .`, hit
Ctrl-C to cancel the original command, and ended up with an abandoned
transaction *on the remote repo* that I couldn't clean up.
Setup:
≻ hg version -v
Mercurial Distributed SCM (version 4.3.3+994-4dc8a2ee0f4f)

I have a bitbucket fork at http://bitbucket.org/spectral54/hg-experimental
(forked from http://bitbucket.org/facebook/hg-experimental). This fork, as
well as the upstream repo, has evolve enabled.
I have the following graph:
@ 3551:fe313cd2 spectral tip @
| basepack: do not keep fd open
| o 3549:f23f3939 spectral
| | basepack: close files after mmap if we never need to remap
| o 3548:22cb1670 spectral
|/ basepack: don't re-mmap if re-reading the same data makes pagedin >
MAXPAGEDIN
o 3540:6a9de6c2 quark
: cdatapack: do not keep fd open
<lots of other stuff>
I wanted to push 3551 as a new head, so I did `hg push -f`, realized it would
push the "lots of other stuff" as well, and hit Ctrl-C. I've trimmed the
output a bit, since I wrote an extension that dumps me into pdb if I hit
Ctrl-C, and then I hit Ctrl-D to exit pdb. I don't think this is relevant, but
it might be. With that removed from the output, the output looks like:
≻ hg push -f
pushing to ssh://h...@bitbucket.org/spectral54/hg-experimental
searching for changes
remote: adding changesets
remote: adding manifests
remote: adding file changes
^C
Alright, now I wanted to do `hg push -f -r .`:
≻ hg push -f -r .
pushing to ssh://h...@bitbucket.org/spectral54/hg-experimental
searching for changes
remote: abort: abandoned transaction found!
remote: (run 'hg recover' to clean up transaction)
abort: stream ended unexpectedly (got 0 bytes, expected 4)
≻ hg recover
no interrupted transaction available
... and this persisted until someone from bitbucket was able to go clean up the
transaction on the remote side.
I don't think it should be possible to break a remote repository in a way that
requires someone to go to that remote repository and run a command. I *do*
have a lot of experimental stuff enabled, including odd extensions. Again, I
have *not* tried to reproduce, either on bitbucket or without bitbucket.
Filing now, here, since #mercurial said I probably should. :) I'll probably
also be filing against bitbucket.
