TooManyConcurrentRequests when saving from editor spawned by bzr-explorer

[Martitza]

1. Launch Bazaar Explorer
2. Open an existing working tree (mine is a checkout, but branches might show the same problem)
3. Select a text file in the working tree browser.
4. Click the icon (under the WT) to Edit the file. ==> Notepad opens on Windows
5. Change some text to mark file as dirty in Notepad.
6. Press Ctrl-S to save ==> get the attached traceback

7. Ignore the error.
8. Notice that subsequent saves work without error.
9. Close and reopen the text file.
10. Notice that subsequent edit+save works without error but that saving is noticeable slow (hourglass appears for ~1 second)
11. Commit change.
12. Go back to steps 3..6. Notice that the error reoccurs.

Note that this trace appears in a dialog box but does *not* appear in the .bzr.log.
It looks like it may actually be local to bzr explorer...

Martitza, do you have lightweight checkout?

As workaround you can change the working tree browser to classic style: main menu -> Tools -> Options -> Working Tree -> select "classic" instead of "qbrowse".

[Martitza (martitzam)]

Yes. I am experimenting with lightweight cbeckouts. (Turns out they
mighT be ok fpr us if we organize our repos a little differently.). I
will try your suggestion today.

Another suggestion: use heavyweight checkouts, aka bound branches
instead of light branches, if you have enough room on your disk to
hold all your history.

[Martitza (martitzam)]

Ok! Instead of my usual "huge" test branch, I've been working with a tiny
branch with only three files. So...

Sure enough, bound branches do not exhibit the Too ManyConcurrentRequests
bug.

So far, only checkouts are showing the TooManyConcurrentRequests bug.

To be clear: the bug occurs on Windows XP using bzr+ssh with bzr 2.2.0 and
bzr-explorer 1.1b1 for lightweight checkouts only.

I have not seen the bug on ubuntu (I have looked) but I am still running bzr
2.1.x on my lucid boxes.

Update and correction (cf. comment #6): I *do* see this bug on Ubuntu.
