File time stamps on initial import

[George Reeke <re...@mail.rockefeller.edu>]

Hello,

I am new to svn, so I'd appreciate a pointer to the answer if this
is a well known problem.  I just installed subversion 1.4.6 on my
RedHat EL 4 system.  I read the book.  I made a repository with
svnadmin create.  I imported my existing project into it with
svn import (using the svn server and the FSFS store).  I did the
initial checkout with svn checkout.

To my horror, the time stamps on all my files were updated to the
time when I did the import.  I realize it's not really important
any more what those time stamps were, except this project has
been going on for many years and I would like to be able to see
when I last worked on a particular file.

So:  Right now, while it's not too late to delete the whole repository
and start over with another copy of my project, can someone tell me
how to import a project into a repository and keep the original time
stamps?  When I make changes and commit them, then of course the
time stamps should be updated accordingly.

Thanks,
George Reeke

Unfortunately, Subversion does not yet support the storage of
timestamps....

It is a well documented bug / feature request:
http://subversion.tigris.org/issues/show_bug.cgi?id=1256

There are a couple of work arounds (That I think are referenced from the
bug entry) of which the most popular is to wrap the commits with scripts
to store the last modified timestamp as a versioned property, however I
do not believe that anyone has ever posted their commit and update
scripts to this mailing list, perhaps someone would be able to?

HTH,

Graeme

Subversion doesn't preserve timestamps.

so if I get you right, your only interested to to preserve the
pre-subversion timestamps?

In that case I would "ls * > tempfile" and "svn propset
LastModifiedTimestamp --revprop -r ImportRev --file tempfile repoURL"

You could also, as Graeme mentioned already, use a versioned property.
In that case a would add an empty directory to the repository first,
check it out over your import folder, 'svn add' all files, set the
custom property on all files and finally commit.

If you are only interested to preserve the original timestamps of the
imported files and not plan to update the properties on each commit, I
would then remove the properties again and commit again. Otherwise you
are stuck with the original value for ever. Might be irritating 8-)
