TypeError: Bit 0 is not a string in ._chk_map_pyx._search_key_255 when called from qbzr

[Matthäus G. Chajdas]

Trying to diff a file at revision 2181 revid:svn-v4:ef33c98e-63e6-0310-b518-990f4ce9efd9:trunk:2200, but getting this error. The repository is converted from SVN, that's why the revision numbers are a bit out of sync.

Do you get the same error when running plain `bzr diff -r N..M` on the same branch? I don't see what we do wrong here in QBzr, but the traceback points deep enough into bzrlib internals.

[Matthäus G. Chajdas (anteru)]

No, I can only trigger it using the GUI, and even then, it's quite complicated ;) The culprit might be that the file has been renamed in revision 2181 (that is, in 2180, it is in core/src/io, in 2181 it's in Core/src/io.)

In the UI, I have to do ...
Explore->Browse items->select the file->right click, show annotate->select revision 2181 in the list on the bottom->show file differences. Show all differences works, as does show tree. Annotate also fails.

Is your project open-source?

No, it's closed source, at least for the foreseeable future. Any way I could get more useful information on my side?

I think we need find a way to either create simple example repo which
can trigger the same bug (rename file in 2 revisions?), or find a way to
trigger the same error from command line.

About the latter: if you run from command line:

bzr diff core/src/io -r2180..2181

and/or

bzr diff Core/src/io -r2180..2181

will it triggers the bug?

[Matthäus G. Chajdas (anteru)]

Both work. I'll try to generate a simple example repo.

[Matthäus G. Chajdas (anteru)]

If I go via log, revision 2181, select the file there, and use "annotate", it works correctly. It's only using the combination by going from explore->browse items. I also checked on Linux, using latest qbzr and explorer, and the error still persists, but it's in .py files (so I could easily hack those.)

I tried to create a simple repository which would exhibit the same error, but no luck :/

[Matthäus G. Chajdas (anteru)]

More information: If I use explore->browse items, select the file, use "show log", and select any of the revisions in the log window, and use "show file differences", it works. It only doesn't work if I use show annotate and use the log in the bottom left (in fact, it fails on _any_ revision.)
