Tv of Sv carefully and repeatdly confirmed, at my request, that after he gets this exception that the new child does exist in the directory! So this exception is somehow not preventing the directory from being updated!

He wrote:

Yeah, I confirmed it again just now.  I took a file already
backed up, 100k11, reversed it with tac, saved it a different
dir in [TestFiles](wiki/TestFiles)1M as 100k12, did tahoe backup, and got the
error message.  I did tahoe ls -l and can see 100k12 in the
correct location, and can successfully see its contents with
tahoe get.

Here's tahoe ls -l after and before:

Hmm, we seem to be getting a trac notification for each github branch that a patch is pushed to (the above patches were pushed to both master and 1742-error-during-post on the official repo), but the branch name shown by trac is always /trunk.

As shown by the test, the assertion was triggered when a version obtained by, e.g. servermap.best_recoverable_version() is used with a (different) new or updated servermap, created after shares of that version have been lost.

Note that using the version obtained by calling best_recoverable_version() on the new/updated servermap would not trigger the assertion. This may explain why it triggered relatively rarely, or why it was coded as an assertion.
