svn:externals revision pegging problem

["Baranowski, Daniel" <db...@LSIJAX.COM>]

Hi All,

 

I've checked the lists and I haven't seen any one with this same
problem, so I'm assuming I'm doing something wrong.

 

I have an external in my trunk, the property looks like this:

MyExternal -r 125 https://ourserver/path/to/repo/sub/folder

 

Now, when in trunk I do an update, I get the MyExternal directory at
revision 125. This is great, this is what I want!

 

Now, if I cd into MyExternal and do an update, I get HEAD. This is not
great, and this is not what I want :(

 

I can go back and for between trunk and MyExternal doing update and each
time it will update to either revision 125 or HEAD depending on where
I'm doing the update from.

 

Is there something that I'm doing wrong, is this just how it works, or
is this a bug?

 

Thanks!

Daniel

I completely forgot that's how subversion worked. I just expected the
revision to be sticky for some reason without even thinking about it.

Using your suggestion, that's pretty much exactly what I did. There were
a lot of files, so I keep having to remind myself that copies are cheap!

I agree that the whole externals thing could use some polish. It's
probably good that I switched to using a tag instead of a revision, that
way when we tag releases, we'll have the correct external code, rather
then HEAD. That's another area externals could be better.

Anyways, thanks for the help!

Regards,
Daniel

The 'external' just tells SVN to maintain a working copy for the given URL and 
revision in the current folder. Updating in trunk therefore updates the WC to 
the given URL and revision. However, inside, this is just a normal working 
copy, so if you update inside, you are not updating to a specific revision 
but to HEAD instead.

I'd say this is as expected, though I agree it could be better. ;)

Suggestion: if r125 is something special, you could give this revision a tag 
and then direct the external to it. It would mean that the external still 
always is updated to head, but the content shouldn't change.

Replace
 MyExternal -r 125 https://ourserver/path/to/repo/sub/folder
with
 MyExternal https://ourserver/path/to/repo/sub/tags/folder-v125
