Updating w/ HEAD revision
There's something I do not understand in Subversion behaviour (1.0.0).
I thought, from the documentation, that "svn update afile" (file) will
update the current file with the latest commited revision of that file,
that is the "HEAD" revision.
I'm using the following repository: https://anciens.enib.fr/svn/engine
in the example below.
Please have a look at the bottom of this email, where SVN output looks
strange to me.
I have two working copies of the same repository on the very same machine.
First working copy is under my home directory (~/SVN/engine),
Second working copy is under /usr/local
I've edited, commited net_backup.sh of the first WC (in my home directory)
I've moved to /usr/local (second WC) and attemped to perform an update:
cd /usr/local/anciens
svn update bin/net_backup.sh
nothing happened
I've tried
svn status bin/net_backup.sh
and svn reported nothing
What I expected was that net_backup.sh in /usr/local/anciens/bin, using
revision 3 would be updated to the last revision, numbered 12.
Nothing happened.
I've tried "svn info" command on both WC, and the results are printed below.
What am I missing, what did I not understand from Subversion ??
I finally got the last revision updated into the second repository by
using an explicit revision option:
svn update -r HEAD bin/net_backup.sh
I do not undersant why it works with this explicit revision and not
without specifying a revision, as svn update states:
svn update --help
update (up): Bring changes from the repository into the working copy.
usage: update [PATH...]
*If no revision given, bring working copy up-to-date with HEAD rev.*
Else synchronize working copy to revision given by -r.
Best Regards,
Emmanuel

You can run 'svn status -v'.
But the most valuable thing is to write a recipe for reproduction, so
that we can witness the problem ourselves.

Ok, maybe a bug ?

I will try, I just don't know if I'm able to reproduce it.
In the event this trouble repeats, is there any command I can run to
grab more info, in order to submit it to this ML ?

That makes no sense, I agree. I've never seen such a behavior before.

There's no difference between 'svn up target' and 'svn up -rHEAD
target'. They're exactly the same, so again, I agree, this makes no sense.
Can you reproduce the behavior somehow? I've never seen this behavior
before, nor have I heard anyone report it, nor can I reproduce it.
