AttributeError this_ie.children in MutableTree committing replacement of a file with a directory

[Eric]

Our installation of Bazaar has been having problems getting hold of enough memory while branching or committing a large repository. I increased the heap size and that got rid of the earlier problems but other problems appeared. The next problem was worked around by removing _patiencediff_c.so which didn't handle failed mallocs correctly. However I just encontered another error while committing (see below). This time it appeared to continue despite the error message. Has the commit succeeded ? Is this error a problem ? Is there anything we can do to avoid the memory issues (perhaps by opting for a less performant option ?) ?

I found that as a result of this error the repository was indeed corrupted (some files didn't make it into the revision).

[Eric (eric-dangoor)]

I have discovered exactly what provoked this error. I was trying to do a commit in which a directory had replaced a file of the same name. This had apparently confused Bazaar.

This sounds like a dupe

Might be related to bug 228234

[Martin Packman (gz)]

Fixed by bug 192859 but more specifically described in bug 205636 which was hard to find because it doesn't actually mention the error anywhere.

[Martin Packman (gz)]

Actually bug 251864 which is a subtle variation on bug bug 205636 and not in fact fixed yet, sorry for the noise.
