Does chg cache information?

[Marcus Harnisch]

Hi all

To make my life a little less miserable I wrote a semi-automatic bridge
between Hg and Clearcase (CC) in the form of a bunch of scripts. The Hg
repo resides in a CC view as unversioned object. To speed up my scripts
(should be an extension really...) I have switched to chg which improves
performance considerably. In a second CC view with its own Hg repo I am
tracking other people's changes. A bit like a vendor branch. Very primitive
indeed.
Recently I ran into the odd situation that one Hg repo appeared to have
lost revisions while the files' contents were up-to-date but shown as
modified. As if .hg had been restored from an old backup. Read-only
experimenting in both repos returned inconsistent results. After a bit of
head scratching I noticed that both shells with their respective CC views
and corresponding Hg repos were executed on the same machine, thus sharing
a chg process, which is such an unlikely situation here that I hadn't even
thought of that before. The thing is that in different CC views, identical
paths point to different file objects. After making sure that both views
are accessed on different machines, i.e. different chg instances,
everything is fine again.

Is it possible that chg caches information about paths and may have used
the wrong information when accessed from the other repo? Not looking for a
fix from your end, just curious if I am on the right track with my
assumption.

Thanks,
Marcus
