#54 RCS lock problem: change cannot integrate

[Anonymous]

Hi All,

We got an RCS error during an integration, which has us puzzled.

The point where the failure is reported is listed below, where RCS ci reports
"no lock set by acao". (acao is the login name of Andrew Cao, the developer.)

When the integration is retried (aeibu, then start integration again from a
new aeib), the failure is repeated. It looks like this change can't be
integrated. It seems that RCS should have a lock on all of the files in the
change, and does not have one on this particular file, and cannot make one.

There is a work-around (aeclone the change, re-pass the review, integrate the
cloned change), which allows us to keep working, but we still have this change
which can't be integrated.

Can anyone shed light on this problem, please?

We are running aegis and Linux version:

I've come across this problem quite frequently, and have finally figured out a solution.

You can try to unlock the offending file (as the file owner) using

rcs -u /usr/local/home/aegis/oss/history/91.uui/9c.uui/a2baa193.4ad/fb46c391.22c/f06458,v

In the event that this doesn't work, you can also just delete the file (it will be rebuilt, with some history information missing).

'find' is a useful command for applying a command to all *,v files:

find /usr/local/home/aegis/oss -name "*,v" -exec rcs -u {} \;

The history_create_command for a project using RCS should include "rcs -U ${quote $history,v}" (note the upper case U), which should prevent this. Does "rlog file,v" indicate that locks are strict for some of your history files? If so, applying "rcs -U" to them as the project user may help. If not, and if files are owned by the project user id, there may be a bug in your version of RCS.

I have had the rcs -U ${quote $history,v} in the config file since day dot, but this didn't prevent the lock issue from rearing its head.

The RCS may be buggy. I'm using 5.7 on Slackware.
