RE: How to create patch for project?

[Miller Dale C Contr AFWA/SDHS]

Mak,

The rdiff -s argument using two dates or two tags gives you good
information.  It shows what files have changed, are new, or removed (in
attic) with revision numbers.  

cvs -Q rdiff -s -Dyyyymmdd -Dyyyymmdd module 

  or

cvs -Q rdiff -s -rtag1 -rtag2 module

(I use version tags that include a date.) 

Output is in the following format:  

File weather/docs/index.html changed from revision 1.9 to 1.10
File weather/docs/links.htm is new; ver_20040823 revision 1.4
File weather/docs/alaska.html is removed; ver_20040524 revision 1.9

Processing this with a perl script could cvs export each file to a staging
area for transferring to another person.

This information gives you a good change list, but it does not show hacking
where files were moved, renamed, or deleted.

A find statement on the $CVSROOT/module each time you hand off an update
would document what is in the repository at the time.

find $CVSROOT/module -type f | egrep -v "Attic|CVS" | sort >module_list

Keep the snapshot under CVS.  I have a module_list snapshot updated and
committed automatically (a cron job) whenever a new file is added to our
repository by touching an "add_flag" file the cron job checks for.

I actually do a find inside a perl program and then removed the ,v and the
$CVSROOT from the path.  I also do not restrict it to -type f so I also have
the directory names (appending an ending slash to the directory names).  The
program also commits the updated the file.
