I want to perform an svn update to a specific date, and I can do this with svn update -r {2010-10-17}
. Unfortunately when this encounters an external it will do the update within the external without passing through the -r {2010-10-17}
option. This results in us getting the correct past revision of the base code, but the latest (undesired) versions of many of the externals.
How can I update to a specific revision or date and have this recurse correctly through the externals?
(Note: I understand that the mistake here might have been to use externals with no explicit revisions specified.)
I hope, anybody will implement my common-sense logic (limited to directory-type externals in some areas) into bash and cmd-script sooner or later and we'll get "definitive answer" to this repeating question
Your base task is:
svn up
your super-repo to needed point in past (updating to date /and without time/ is, BTW, not a best choice, but - apllicable)svn propget svn:externals -R
(-R in order to check the whole tree without a lot of cd
). - https://subversion.assembla.com/svn/subversion-trouble-shooting/trunk/lib lib
): cd to the last field of string /relative to the first field, which is, in turn, is relative path to root/ and svn up to the same point, as it was done for superrepo: svn update -r {2010-10-17}
As result you'll have Mixed Working Copy, but superrepo and externals will be in state "for some revision in the past"
Note:
Additional sample for constructing local path to directory with externals (nested WC really) on more complex case.
