Source: diffoscope
Version: 84
Severity: normal
Dear Maintainer,
diffoscope 84 ftbfs in Ubuntu artful (and I think experimental but haven't
checked this yet) with failures like this:
________________________________ test_item1_elf ________________________________
differences = [<Difference nm -s {} -- nm -s {} []>, <Difference
alloc_system-d16b8f0e.0.o -- alloc_system-d16b8f0e.0.o []>, <Differ...r -dump
{} []>, <Difference find {} -execdir llvm-dis -o - '{}' ';' -- find {} -execdir
llvm-dis -o - '{}' ';' []>]>]>]
@skip_unless_tools_exist('nm')
@skip_if_binutils_does_not_support_x86()
def test_item1_elf(differences):
assert differences[1].source1 == 'alloc_system-d16b8f0e.0.o'
assert differences[1].source2 == 'alloc_system-d16b8f0e.0.o'
expected_diff = get_data('rlib_elf_expected_diff')
> assert differences[1].details[0].unified_diff == expected_diff
E IndexError: list index out of range
I'm fairly sure this is down to this change in behaviour in readelf:
(artful-amd64)root@aeglos:/tmp# readelf --wide --decompress --hex-dump=.data
alloc_system-d16b8f0e.0.o
Section '.data' has no data to dump.
(artful-amd64)root@aeglos:/tmp# echo $?
1
vs:
(sid-amd64)root@aeglos:/# readelf --wide --decompress --hex-dump=.data
/build/alloc_system-d16b8f0e.0.o
Section '.data' has no data to dump.
(sid-amd64)root@aeglos:/# echo $?
0
which in turn is down to
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=32ec889602502348b704cfb16e65c83dc3eec095
On thinking about this, I think this is arguably a binutils bug so I've filed
https://sourceware.org/bugzilla/show_bug.cgi?id=21820
too. But I thought you might want to know :) I can't see any very easy way of
working around this in diffoscope but I'm new to the codebase.
Cheers,
mwh

binutils upstream went on and reverted to the previous behaviour of not
erroring out in the "dump an empty but present section" case, so
diffoscope tests passes with binutils 2.29 + the fixing commit (tested
with the new binutils upload to unstable and artful).
Therefore, I'm closing this bug.
