Обсуждение: Short CVS question, history

Hi,

I have a short CVS question please: How do I go from a particular file
revision like

pgsql/cvs/pgsql/src/backend/parser/parse_relation.c.1.3

to the complete commit? I.e. I would like to navigate back from this
particular file to the commit and see all the other files that were
touched by the commit.

Also, is it possible that you moved the CVS repository once and lost
some history?

Thanks!

Dirk

There's more than one way to do it.  One way is

    cvs diff -c -D'timestamp1' -D'timestamp2'

where the timestamps bracket the commit you're interested in.  For
commits after 2004 or so, you can also check out the corresponding
message in the pgsql-committers archives
http://archives.postgresql.org/pgsql-committers/

Not that I'm aware of; though of course the project CVS goes back only
to 1996 and not into the Berkeley era.  Is there something in particular
you're concerned about?

CVS isn't very good at this. As Tom Lane noted, your best bet is to do
it by checking a narrow time window around the time the file of interest
was changed. If commit activity isn't too high this is generally just fine.

This is one of the (many) problems with CVS that Subversion solves. Not
that it solves all of them, mind you.
