Subject: spdx_common: modify UNPACKDIR instead of WORKDIR in get_patched_src()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=aa44a0f0eb5e260959ebd77f439a5d25b3c1aa2a;p=thirdparty%2Fopenembedded%2Fopenembedded-core.git

spdx_common: modify UNPACKDIR instead of WORKDIR in get_patched_src()

This change will affect the SPDX output: the source file path will no
longer be prefixed by `sources/`.

The rest of the changes are safe because:
- `S` should reference `UNPACKDIR` and not directly reference `WORKDIR`.
- After analyzing all public layers, no `do_unpack()` or `do_patch()` was
  found to reference the `${B}` variable. The comment mentioning the
  `${B}` variable traces back to [1] (though no further explanation was
  provided).

Additionally, this ensures proper capture of sources if the recipe
modifies `UNPACKDIR` outside of `WORKDIR` (though such cases should be
rare).

With these changes, SPDXWORK is no longer a working directory which is
"temporary" replacing WORKDIR, it is now a "temporary" directory containing
unpacked source files.
The run.do_patch.XXXX and associated files are now stored in ${WORKDIR}/temp.
