[Valgrind-developers] Subversion question

[Nicholas N. <nj...@cs...>]

Hi,

The nightly tests would be much more useful if they told us how the 
results for each machine changed since the previous night.  I want to 
change the script so it checks out the current HEAD, and the HEAD from 24 
hours ago, and tests both and shows the difference in results.

CVS has a nice -D flag, where you can ask to check out the HEAD from 24 
hours ago.  AFAICT Subversion doesn't have this;  you can specify a date 
to check out from, but it always checks out the repo from midnight on that 
day, which isn't precise enough.

The only way I can see how to do it with Subversion is look at the "svn 
log" output and work out which revision number applies to 24 hours ago, 
but that requires parsing that output and futzing with dates to work out 
when 24 hours ago was and it all sounds horrible.  Can anyone think of a 
better way to do it?

Thanks.

N
