[PATCH 0/4] devtool fixes

[Paul Eggleton]

A few fixes for devtool, mostly relating to recipes that fetch from git
where S points to a subdirectory of the repo.

Note: I wasn't 100% sure if it was appropriate to be referencing WORKDIR
in patch.py; let me know if I should try to rework that.


The following changes since commit db28cd0e1540e44db963108430205c8c0c817774:

[PATCH 1/4] patch: handle if S points to a subdirectory of a git repo

[Paul Eggleton]

From: Paul Eggleton <paul.eggleton@microsoft.com>

If PATCHTOOL = "git", SRC_URI fetches from a git repo and S points to
a subdirectory of the checked out sources, then we were erroneously
initialising the subdirectory as its own git repo. Check if the returned
top-level repo directory is a subdirectory of WORKDIR and do not
run initialise the source directory if that is the case.

(This was a regression introduced with OE-Core revision
6184b56a7a0fc6f5d19fdfb81e7453667f7da940, however we didn't have a test
that verified the behaviour.)

[PATCH 2/4] devtool: finish: handle patching when S points to subdir of a git repo

[Paul Eggleton]

From: Paul Eggleton <paul.eggleton@microsoft.com>

If devtool finish needs to create a patch and have it applied to the
sources for a recipe where S points to a subdirectory of the sources,
then the patch needs to be applied at the root of the repo i.e. we need
to add a patchdir= parameter to the SRC_URI entry.

[PATCH 3/4] devtool: ignore pn- overrides when determining SRC_URI overrides

[Paul Eggleton]

From: Paul Eggleton <paul.eggleton@microsoft.com>

If (perhaps foolishly) at your configuration level you have e.g.

  SRC_URI_append_pn-recipename = " file://patchname.patch"

and then run devtool modify on a different recipe, an error occurs:

  INFO: SRC_URI contains some conditional appends/prepends - will create branches to represent these
  ...
  ERROR: [Errno 2] No such file or directory: '/path/to/downloads/patchname.patch'

pn- overrides would not constitute an alternative configuration that we
should handle in this context, so just ignore them to avoid the issue.

[PATCH 4/4] oe-selftest: devtool: test modify git recipe building from a subdir

[Paul Eggleton]

From: Paul Eggleton <paul.eggleton@microsoft.com>

Add a test that verifies that devtool modify + devtool finish do the
right thing on a recipe that fetches from git and sets S to point to
a subdirectory of the source tree. We have a few examples among the core
recipes, dos2unix is a convenient one so let's use that. (The test first
verifies that that is still true in case the recipe is changed in
future.)

It is probably ok. The code won't pick up on the variable usage from a
hash perspective there but it would be referenced elsewhere anyway.

There was a failure which is probably from this series though:

(I've not confirmed it was the series, I'm just guessing)

Hmm, yes, it probably is. I did run the tests but somehow I didn't see this
failure. I'll investigate further.
