decent cache format

[Alexandr Litjagin]

bzr-svn needs a new cache format, preferably based on standard bzr data formats. The current formats have some disadvantages:

 * tdb: not available on windows
 * large files
 * sqlite: only one writer
 * extra dependencies
 * hard to pull across from another machine

The data doesn't have to be changed and can be thrown away if there's a reason for it - once the information for one revision is known it won't change.

the iter_inventories() bug has been fixed.

The first error is a known limitation of the SQLite cache that bzr-svn uses. You can either install python-tdb (not sure if it's available on Windows) or avoid running multiple bzr processes that access the same Subversion repository.

Why is the priority "Low"?
This is a show stopper on windows - one cannot even checkout a repository!

[Jelmer Vernooij (jelmer)]

It's only a problem if you run multiple instances of bzr-svn on the same repository.

... concurrently.

and what i sould do to avoid it?

[Jelmer Vernooij (jelmer)]

The workaround (until a better cache format is in place) is to install python-tdb. (if you're on Linux) or avoid running multiple bzr processes that use the same Subversion repository concurrently (if you're on Windows).

i have instaled tortoisebzr, that is always shows runig and shows context menus an files status in overlay icons, is it alredy one such process?

So there is no way to use it with bzr-explorer?

I'm not aware of the way that bzr-explorer works. If it uses multiple
processes that all need to access the subversion repository then it will
indeed not work on Windows in its current form.
