Summary: abort: unknown revision during outgoing/push when
there are no changes and hidden changesets are present
Severity: bug
Classification: Unclassified
OS: All
Reporter: gregory.szorc at gmail.com
Hardware: All
Status: UNCONFIRMED
Version: 2.8-rc
Component: Mercurial
Product: Mercurial
I don't have STR, but I believe I stumbled across a legit bug in obsolescence
support.
I am running `hg out` on a repository that has many hidden and obsolete
changesets created through a combination of `hg amend` and `hg rebase`. To my
surprise, this command exists with "abort: unknown revision X" where X is a
full hex identifier.
$ hg out collab

searching for changes
abort: unknown revision 'd097ca031e604879dfc231f793f060326e39738b'!
The changeset does exist (although it is hidden):
$ hg --hidden log -r d097ca031e604879dfc231f793f060326e39738b
changeset: 168351:d097ca031e60
parent: 168282:855da6d8a327
user: Gregory Szorc <gps at mozilla.com>
date: Thu Oct 17 13:56:29 2013 -0700
summary: Bug 927837 - Capture AC_OUTPUT and AC_HEADER_OUPUT dependencies to
config.status
The changeset exists in phaseroots:
$ grep d097ca031e604879dfc231f793f060326e39738b .hg/store/phaseroots
1 d097ca031e604879dfc231f793f060326e39738b
The changeset is referenced is obsolescence data. Relevant entries from
debugobs:

I can reproduce the abort on `hg out` with current tip (1d7a36ff2615). If this
is a repository corruption issue, that occurred while using 2.7.2.
