Comment 1 for bug 1668555

I've just hit this bug when snapping a project. Part1 works fine, but part2 fails with RecursionError.

    parts:
      part1:
        plugin: dump
        source: src
        organize:
          lib: lib2

      part2:
        plugin: dump
        source: src
        organize:
          lib: lib/lib

When investigating this I came a cross another odd behavior: the organize section seems to be applied in the stage step and not in the install step.

    $ snapcraft clean && snapcraft build part1
    Cleaning up priming area
    Cleaning up staging area
    Cleaning up parts directory
    Preparing to pull part1
    Pulling part1
    Preparing to build part1
    Building part1
    $ find parts stage -type f
    parts/part1/src/lib/hello.txt
    parts/part1/state/pull
    parts/part1/state/build
    parts/part1/build/lib/hello.txt
    parts/part1/install/lib/hello.txt

Note the directory install/lib. I would expect it to be install/lib2 after build.

    $ snapcraft clean && snapcraft stage part1
    Cleaning up priming area
    Cleaning up staging area
    Cleaning up parts directory
    Preparing to pull part1
    Pulling part1
    Preparing to build part1
    Building part1
    Staging part1
    $ find parts stage -type f
    parts/part1/src/lib/hello.txt
    parts/part1/state/pull
    parts/part1/state/build
    parts/part1/state/stage
    parts/part1/build/lib/hello.txt
    parts/part1/install/lib2/hello.txt
    stage/lib2/hello.txt

Now, after staging the install dir has been renamed to install/lib2. This can't be right that stage modifies what is produced when building parts. However, the effect is that stage/lib2 comes out ok.

When staging part2 snapcraft fails with a RecursionError.

    $ snapcraft clean && snapcraft stage part2
    Cleaning up priming area
    Cleaning up staging area
    Cleaning up parts directory
    Preparing to pull part2
    Pulling part2
    Preparing to build part2
    Building part2
    Staging part2
