Perhaps I'm reading that 2nd link incorrectly, but it looks like loading a
dump file into an existing repository can break date based revisions
regardless if the load is done while the repository is r/w, r/o or

Here's a snippet from the bug report:

       this will affect all repositories which have received an import from
       a dumpfile (assuming the import contains commits older than HEAD,
       which invariably it does).

Soo, assuming I'm interpreting that statement correctly (and I'm not
saying I am) it doesn't matter if I leave the repository r/w, change it to
r/o or take it offline, if the dump file contains commits older then the
latest revision in the repository this problem will occur.

My original question was specifically related to loading a dumpfile into
an active **R/W** repository and it sounds like this problem isn't
specific to that... the key being "loading into R/W".

Most of the time when I load a dump file into an existing repository I
take the repository offline. If I have leave it up, I change it to r/o.
I haven't (yet) come across a situation where I HAD to leave the
repository r/w while doing the load, but expect that may happen and just
wanted to know if there were any issues specific to loading into a r/w

Don't get me wrong, I wasn't aware of this particular issue and I'm very
thankful you brought it to my attention, but I want to make sure this is
NOT specific to loading into a R/W repository.

Is there a way to correct the "date based revision" problem, eg, could I
dump the ENTIRE repository, re-create it and re-load? Will the dump be
created in date order?
