Crash in bzr-svn trying to branch python trunk

This is a memory leak. As the bzr-svn operation proceeds, memory used by the bzr process increases slowly but steadily, until all physical memory is used, at which point the crash occurs.

Similar behaviour occurs with bzr pull from a svn branch.

[Paul Moore (pmoore)]

This is related to the bzr-svn plugin, rather than to bzr core.

[Adrian Wilkins (adrian-wilkins)]

The memory leak errors produce relevant MemoryError exceptions, this looks more like a dupe of the broken http:// support bug.

[Paul Moore (pmoore)]

I don't believe it is. Jelmer claimed that bug 190832 "is a known issue in the http(s) support in the 0.4 branch at the moment. It should work fine in any releases". I'm using a released version (0.4.7) so I don't think it applies (unless I'm misreading Jelmer's comment - but if so, I don't see what it *does* mean).

The bug is certainly an issue of running out of memory - RAM use increases until physical memory is all used, and then the program crashes. Frankly, as things stand, the plugin is unusable for me on large trees. I have given up with it until this issue is fixed.

[Jelmer Vernooij (jelmer)]

It's probably a memory error in python-subversion. Are you using a recent version of Subversion 1.5? If not, this bug should probably be reassigned to Subversion.

[Paul Moore (pmoore)]

I am using the binary build provided by Kevin Light, which claims to include the patches to the python-subversion bindings to fix the memory leak. I cannot build Subversion (or the Python bindings) myself, so I have to rely on Kevin's binary.

So, either:
1. Kevin's binaries don't actually contain patched python-svn bindings,
2. The python-svn patch doesn't work, or
3. This is an unrelated bug

I'm very sure it at least fixes some memory issues.

It may well be this, but at least I can't reproduce it here locally
then. It may also be windows-specific in some way.

Cheers,

Marking as duplicate of #191731 because both appear to involve memory problems on Windows that are unreproducible on Linux.

[Jelmer Vernooij (jelmer)]

This should've improved now that bzr-svn has its own bindings.
