[Monotone-devel] weird monotone behavior

[Hugo Cornelis]

Hi,

I am using monotone 0.40 statically linked, downloaded from the
monotone website on a redhat enterprise server 5.  I encountered the
following problem:

I have a project that uses a database ~/neurospaces_project/MTN/installer.mtn

I pulled an external database of the same project to
~/neurospaces_project/MTN/neurospaces-developer.mtn

Changed the options files in a workspace, then did the things below.
In a summary, after changing the option file, asking for a log
overwrites the options file and makes it invalid.  Changing back to
the original database did not help.

Not sure if I am doing something wrong, but monotone making the
options file invalid makes me feel uncomfortable :(

If I do a fresh checkout in a temporary directory, everything seems
fine and monotone behaves as expected without problem.

[19:39] (0,2) tmp $ mtn co --db
~/neurospaces_project/MTN/neurospaces-developer.mtn -b 0 .


Below the differences between the two directories.  Seems that the
'new_manifest' line is the only significant difference.
