Segmentation Fault (was Re: CVS sticky information ignored on import)

Thanks Greg.

Ah, the tantalising 'by default'... I was hoping there would be some
way to persuade CVS to use the sticky data from the administrative
"CVS" sub-directories for the import. After all, the command does take
kflags and release tags as arguments!

I have ended up using the following instead:

find . -name Entries | xargs grep "/-kb/" \
  | sed -e "s|CVS/Entries:/||" -e "s|/[^/]*/[^/]*/-kb/.*||" \
  | xargs cvs -d $CVSROOT admin -kb

Actually that's not true, because if there are any files marked -kb in
the sandbox which are not imported because they're on the default CVS
ignore list, the admin command SIG_SEGVs.

Hence I've copied this to the gnu.cvs.bug list; if anyone is
interested, I can give you the exact script I'm running and the
sandbox source tree I'm running it on (which is
ftp://ftp.mozilla.org/pub/mozilla/releases/mozilla0.9.8/src/mozilla-source-0.9.8.tar.bz2
BTW).

For archive purposes, if anyone else is trying to do the same thing I
circumvented the segfault problem by creating an 'ignore' list from
the original import (| grep "^I " | grep -v "CVS$" >> $CVSIGNORELIST)
and then

for i in $(find . -name Entries | xargs grep "/-kb/" \
  | sed -e "s|CVS/Entries:/||" -e "s|/[^/]*/[^/]*/-kb/.*||");
  do grep $i $CVSIGNORELIST || cvs -d $CVSROOT admin -kb $i; done

If anyone can think of a better way to determine which files not to
admin (e.g., using an exit code from cvs to determine whether the file
is in the repository) I'd love to know.

thanks,
Hamish

Unfortunately that's what I'm doing!

Unfortunately that's also what I'm doing!

Well... mozilla uses CVS, and whatever I used I'd need to
differentiate between text and binary files.

Thanks again.
