Subject: [PATCH] Add option to have unique debug source dirs across
version/release/arch.
Introduce a new macro _unique_debug_srcs that when set will pass
--unique-debug-src-base "%{name}" to find-debuginfo.sh which will
move sources into a unique "<name>-<ver>-<rel>.<arch>" directory
under /usr/src/debug/ and makes debugedit rewrite the source paths
in the debuginfo to use that unique directory name.
Traditionally the debug src dir was named after the builddir which
was defined through the %setup macro which used the -n name argument
to define the builddir name and source archive to use. The builddir
might not be unique though between package versions.
Now that debugedit doesn't have strict base and dest dir length
restrictions for rewriting the source dir paths this can now be made
more flexible.
The added testcases show the difference between the old and new way.
The hello2.spec file defines the name of the package as hello2, but
uses the %setup marcro with -n hello-1.0 to use the hello-1.0.tar.gz
archive. This would traditionally result in a hello-1.0 builddir
which would be moved under /usr/src/debug. Possibly conflicting
with any other package (version) that used the same builddir name.
When defining _unique_debug_srcs to 1 that builddir will be moved
to <name>-<ver>-<rel>.<arch> instead (hello2-1.0-1.<arch>).
The testcases check that both the actual package source filess under
/usr/debug/src/ and the source paths as found in the .debug files are
under the traditional or new unique directory names depending on whether
the new _unique_debug_srcs macro is defined.
