Subject: [PATCH] find-debuginfo: Check files are writable before modifying
|
||||
them
|
||||
|
||||
Since commit dfe1f7ff3 ("find-debuginfo.sh: Exit with real exit status
|
||||
in parallel jobs") there is a check whether gdb-add-index worked
|
||||
correctly and find-debuginfo would fail (even in parallel mode) if an
|
||||
error occured.
|
||||
|
||||
This turned out to show that gdb-add-index needs write permission to
|
||||
add the gdb index to the file. This is also the case for a couple of
|
||||
other things, like running objcopy --merge-notes. debugedit and
|
||||
add_minidebug already made sure it had write permission.
|
||||
|
||||
To make sure find-debuginfo doesn't (partially) fail extend the
|
||||
writable check to include the gdb-add-index and objcopy --merge-notes
|
||||
invocation.

Subject: [PATCH] find-debuginfo: remove duplicate filenames when creating
|
||||
debugsources.list
|
||||
|
||||
We remove duplicate filenames when we _process_ debugsources.list.
|
||||
However, this means that momentarily we may have a very large
|
||||
(in the range of *giga*bytes) debugsources.list.
|
||||
|
||||
This is unnecessary, we can also remove dups when we *create* it.

Subject: [PATCH] find-debuginfo.sh: Exit with real exit status in parallel
|
||||
jobs
|
||||
|
||||
Currently, when the script is executed in parallel (-jN), the
|
||||
resulting exit status will always be 0.
|
||||
|
||||
The script execs an appropriate number of clones of itself, calling
|
||||
run_job to run the actual workload. This then calls do_file(), saving
|
||||
the exit status into "res.$jobid".
|
||||
|
||||
In do_file(), though, if an error occurs, exit is called. This causes
|
||||
the entire exec'd shell to exit with status 0 (since there are almost
|
||||
always echo calls as the last executed statement). The real exit
|
||||
status is therefor never written to the "res.$jobid" files by run_job().
|
||||
|
||||
The simple solution is to use 'return' instead of 'exit'. A number
|
||||
of minor adjustments are also made to propagate this properly so that
|
||||
it is reported as the correct exit status.
|
||||
|
||||
While at it, I've incorporated a patch for find-debuginfo/30505.
|
||||
Using this patch and another patch to the RPM package (submitted as
|
||||
github issue #3215), failures of gdb-add-index.sh will now properly fail
|
||||
the build instead of being swallowed. It should be much easier for
|
||||
developers to figure out why their builds have failed should gdb crash.
