1. Summarise the issue (what were doing, what went wrong?)
2. What behaviour were you expecting instead?

I've managed to get a repo into a strange state where "darcs whatsnew -l" shows some files that should be considered boring:


angel-dfly misc-pri $ darcs show repo
         Format: hashed, darcs-2
           Root: /home/falsifian/tmp/misc-pri
   PristineType: HashedPristine
          Cache: thisrepo:/home/falsifian/tmp/misc-pri, cache:/home/falsifian/.cache/darcs, repo:/home/falsifian/w/misc-pri, repo:., repo:exoco.falsifian.org:w/misc-pri
     PatchIndex: enabled, but not yet created
boringfile Pref: .boring

angel-dfly misc-pri $ cat .boring


# LaTeX (and BibTeX) output





angel-dfly misc-pri $ darcs whatsnew -l
a ./programming/s3d/src/build/
a ./programming/s3d/src/build/ttc/
a ./programming/s3d/src/build/ttc/S3D/
a ./programming/s3d/src/build/ttc/S3D/LinearAlgebra.ttc
a ./programming/s3d/src/build/ttc/S3D/LinearAlgebra.ttm


Maybe worth noting: there are a lot of other files under programming/s3d/src/build which are correctly ignored. I don't know what's special about LinearAlgebra.{ttc,ttm}.

I don't know how I got the repo in this state. I have saved a .tar.gz of the offending repo, and can reproduce by untarring it. Unfortunately the repo has some private data so I'd rather not share the whole thing.

If I clone the repo and then move the build directory to the new repo, the problem doesn't happen:


angel-dfly misc-pri $ cd ..
angel-dfly tmp $ darcs clone misc-pri misc-pri_1
Copying patches, to get lazy repository hit ctrl-C...    
Finished cloning.                                                               
angel-dfly tmp $ mv misc-pri/programming/s3d/build misc-pri_1/programming/s3d
angel-dfly tmp $ cd misc-pri_1
angel-dfly misc-pri_1 $ darcs whatsnew -l
No changes!


Even if I then replace _darcs with the one from the broken repo, the problem still doesn't happen:


angel-dfly misc-pri_1 $ rm -r _darcs
recursively remove _darcs? y
angel-dfly misc-pri_1 $ mv ../misc-pri/_darcs .
angel-dfly misc-pri_1 $ darcs whatsnew -l
No changes!
exit: 1 angel-dfly misc-pri_1 $ 


I don't know enough about Darcs to investigate further. This all seems pretty strange.

3. What darcs version are you using? (Try: darcs --exact-version)

I may be wrong but it looks to me as if your build process somehow went 
wrong or was started from the wrong directory. Note the difference 
between boringfile:


and output of whatsnew -l:

a ./programming/s3d/src/build/

This path does not match the boringfile regex because of the 
intermediate "src" directory. The files you moved into the clone also 
don't have the "src" directory.

You're right, I wasn't reading the output carefully enough, and indeed programming/s3d/src/build has those two rogue files LinearAlgebra.ttc and LinearAlgebra.ttm. So, PEBKAC, not a Darcs bug.
