Bug ID: 3954

Assignee: bugzilla at selenic.com
Summary: revlog: LookupError on filename @README.txt
Severity: bug
Classification: Unclassified
OS: Linux
Reporter: victor.stinner at gmail.com
Hardware: PC
Status: UNCONFIRMED
Version: 2.4.1
Component: Mercurial
Product: Mercurial
Hi,
Someone added a new file called @README.txt to the repository of the Python
project (http://hg.python.org/cpython). After that, I got some HG errors. I
removed the repository and created a new clone: the error was gone. It looks
like the problem only occurs on an existing repository which was updated, not
on a fresh clone.
I tried to reproduce the bug on a simple repository, but I failed to reproduce
it :-/
I'm using the share mode with the following directories:
.../default: default branch
.../2.7: share with default, 2.7 branch
.../3.3: share with default, 3.3 branch
.../3.2: share with default, 3.2 branch
The @README.txt issue was discussed on python-committers mailing list:
http://mail.python.org/pipermail/python-committers/2013-May/002565.html
Antoine Pitrou ran "hg verify" on the HG server: no error. See:
http://mail.python.org/pipermail/python-committers/2013-May/002571.html
Here are some infos below. Tell me if you need more.
