svn mirror lost (and being recreated) [message #25880]

Playing with googlecode wiki, we have unfortunately lost svn mirror (because wiki commits to googlecode svn and thus made mirror out-of-sync).

I am recreating the mirror right now, but it is a long process (about 100 commits / hour....).

Hi,

I had the same problem. I guess, since it is a new repository, you have to checkout from start again. That's what I did.
Now, it still seems that this repository lags behind because the nightly builds are ar 2246 and the repository mirror only has until rev 2241.

Unfortunately, the issue is still not resolved. I will have to delete and recreate the repository at least one more time.

The problem perhaps is that googlecode uses svn 1.6 and we are still at 1.4. With this setup, mirroring stops at revision ~300 with some weird error.

The current mirror is created by dumpimg primary repository, creating yet another repository in ubuntu 9.10 and mirroring that. Unfortunately, with that mirror, I cannot continue with 8.04.

I have one more thing to try, if that fails, I will perhaps rather wait until next ubuntu LTS (in next months) then upgrade the OS of server...

Try maybe "Relocate" in TortoiseSVN. (although I'm not sure it will work in this case, but it's very likely)

I also had the same problem. But there is a simple solution Smile

.

Go in you're .svn repository and modify the 'entries' file, it contains the UUID: just update it to the new value, and you're rolling again Wink

Would it be difficult to make the subversion commit logs available for download on the downloads page so that, without access to the svn mirror, it would still be possible to see what exactly has changed in the latest nightly builds?
And another question; are the sources in the upp-x11-src-NNNN.tar.gz archive the same as those installed with the windows installer? I am not very fond of installers, you see.

have a nice day,

frank

Yes. And the number NNNN is svn revision.

Mirek

P.S.: Here is the plan: I will try to install svn 1.6 from sources. Means svn will off-line soon...

Why from sources ? Ubuntu default svn is 1.6.5....

Ciao

Max

p.s.: ah, I've seen that you're using LTS 8.04 release.... you could try PPA instead :

it seems as if the svn tree crash has introduced a marginal issue, for those guys using git at least.

mirekt said that 'somewhere around revision ~300 it made an error'
well it must be rev 328, since it has commit time march 20, 2010

which is no big deal, except that the git from download page has been created from the former, proper svn tree. which had that special commit set right.

now, when people are converting svn -> git they end up with a split history at that point (rev 328).

how to deal with it?

is there a possibility to modify/hack that special commit in SVN to reflect the same date? so git would work again? (merging and sharing is not possible otherwise)

beein that said, again, i vote for switching to git..the repositories can be recreated a lot esier Smile

(since the full history is always somewhere around with any developer).

Gitorious / github are as good as google code..(which still sticks to svn)

at least, is it possible to regenerate the upp-mirror from the upp server, where the history is not corrupted?

Well, I am adding to RM this (I mean, next attempt at recreating mirror), but do not hold your breath...

i think, in case of emergency, you could convert the git repo (from tojockey?) back to svn again..

mirek, what is your stand towards git Very Happy

you could save yourself a lot of hassle..
i could help in deploying the stuff..

If it ain't broken, do not fix it...

Right now, svn serves mine and U++ purposes quite well IMO. I estimate costs of migrating to git at about 4-8 MD. Not going there unless I have to.

then the git repo from download section should be changed..
but it seems we wont get rid of the split history anytime soon as long as we dont switch to git completely.

not neccessarily.. you can take the git that already exists (mine i.e), the work is probably 80% done. well, i admit, i dont have a picture how the svn process works in upp.. but i'm sure it is possible with git too.

i can asure you, once started git, you wont ever miss svn + it makes colaborating a lot esier (patch creation / apply inclyded)

The cost of actual migration alone is most likely low. Anyway, you have to consider the infrastructure as whole - automated mirrors, nightly builds, users, passwords, access rights - all of that would have to be at least tested.

just out of curiosity..
how many developers are currently involved in upp, i mean thos with commit rights?

BTW: gitorious supports user management as well...
remains the nightly builds, which is not quite the problem i think actually git is fully command line. automatic mirrors are just a matter of one command

sure, it's kind of work to migrate, in total. but this'd be part of the rejuvenation upp is facing, started with Redmine Smile
