Suppose I have some svn:externals set up to pull in some resources from elsewhere in my repository:

../../path/to/scripts scripts
../../path/to/data data

I want each part of a working copy to all come from the same revision, so I don't want to pin these externals to a particular revision number. If I simply do an svn up, this works like I'd want it to:

Fetching external item into 'scripts':
External at revision 15000.

Fetching external item into 'scripts':
External at revision 15000.

At revision 15000.

However, if I try to check out a particular revision (using something like svn up -r 144444), the externals still come from the latest revision:

Fetching external item into 'scripts':
External at revision 15000.

Fetching external item into 'scripts':
External at revision 15000.

At revision 14444.

Is there some svn:externals syntax or some canned script or command that I can use to easily update a working copy, including all of its externals, to a particular revision?

(In particular, I don't want to do svn --ignore-externals, because I want to also update the externals to a particular revision, and I don't want to peg the externals to a fixed revision, because I generally want them to track HEAD.)

  • [This script](https://gist.github.com/Orangenhain/3413952) (which I haven't tried) is one approach to automating a checkout of a particular revision of a directory and its externals. – Josh Kelley Aug 21 '14 at 15:04

There are not easy way without PEGged externals (and maintain "always HEAD" with pegged externals is a/ easy b/ handwork with possible automation)

For "time-back machine" with not-pegged externals in order to return state of the whole WC to the state at revision N in master repo you have to perform:

  • in wrapper-WC svn log -l 1 -r N and write timestamp DATE of this revision
  • For each externals in each externals WC svn log -l 1 -r {'DATE'} and write revision number (X,Y,Z)
  • svn up -r N
  • svn up -r (X|Y|Z) in WCs of externals

Resulting mixed Working Copy will be neeed for you result (not 100% guarantee, because between revisions N and N+1 revisions of externals may be also updated, but you haven't traces of it)

  • To clarify, each of my externals comes from elsewhere in the same repository, so concerns like matching dates and externals getting commits between revisions N and N+1 of the master repo don't apply. But thanks for the confirmation that there's no automated way of doing this. – Josh Kelley Aug 20 '14 at 17:04

    @JoshKelleyv - well, for the single repository time-back **can be** automated with rather short bash, because extracted date will be used with all externals (and all externals you can get with `svn pg -R`) – Lazy Badger Aug 20 '14 at 19:27
