[PATCH v2 3/4] libpsl: Do not embed the build path in suffixes_dafsa.h

[Khem Raj <raj.khem@gmail.com>]

The generated src/suffixes_dafsa.h records the public suffix list it was
built from in _psl_filename[]. meson feeds psl-make-dafsa an absolute
input path, so the full build directory gets baked into the header and,
through it, into the library and its -src/-dbg packages. On an
autobuilder whose build tree lives under $HOME/TMPDIR this trips the
buildpaths QA check with references to both TMPDIR and the build host
HOME directory, and it makes the build non-reproducible.

The absolute path is useless on the target: it is only consumed by
psl_builtin_outdated() to stat() the source list, which never exists on
the running system. psl_builtin_filename() is documented to return "the
file name", so embed only the basename.

Fixes

ERROR: libpsl-0.23.0-r0 do_package_qa: QA Issue: File /usr/src/debug/libpsl/0.23.0/src/suffixes_dafsa.h in package libpsl-src contains reference to TMPDIR [buildpaths]
ERROR: libpsl-0.23.0-r0 do_package_qa: QA Issue: File /usr/src/debug/libpsl/0.23.0/src/suffixes_dafsa.h in package libpsl-src contains a reference to the build host HOME directory. If upstream hardcodes a directory path that matches your home, you can set OEQA_BUILDPATHS_SKIP = "/srv/pokybuild" in the recipe. [buildpaths]

+Subject: [PATCH] psl-make-dafsa: embed only the basename of the input file
+
+The generated suffixes_dafsa.h records the path of the public suffix
+list it was built from in _psl_filename[]. meson passes this input as an
+absolute path (meson.current_source_dir()/list/public_suffix_list.dat),
+so the full build directory ends up baked into the header and, through
+it, into the compiled library and its -src/-dbg packages. This is not
+reproducible and trips the OE buildpaths QA check (references to TMPDIR
+and to the build host HOME directory) when the build tree lives under
+those prefixes on an autobuilder.
+
+The absolute path is useless on the target anyway: it is only consumed
+by psl_builtin_outdated(), which stat()s _psl_filename and compares its
+mtime; the build-host path never exists on the running system so the
+stat always fails. psl_builtin_filename() is documented to return "the
+file name of the Public Suffix List file", so a basename is in fact the
+more faithful value.
+
+Embed only os.path.basename() of the input. The unmodified path is still
+used to open, stat and checksum the file, so only the leaked string
+changes.
