This function was not aware of --leaf-changes-only mode.
- Stats counters for changed variables and types have
different names in the different modes.
- Net leaf type changes were not included in leaf mode.
For some inputs, this resulted in abidiff producing an empty report
but returning a non-zero exit status in --leaf-changes-only mode.
For other inputs the combination of both issues still resulted in the
correct return code. This included the following test-abidiff-exit
test cases:
- test-leaf-peeling
- test-leaf2
- test-no-stray-comma
This patch makes corpus_diff::has_net_changes mirror emit_diff_stats,
modulo flags like --non-reachable-types which if absent can still
result in discrepancies between output and return code.
To achieve this in a more maintainable way, the patch introduces a new interface
reporter_base::diff_has_net_changes. That interface is implemented by
all current reporters. Each reporter focuses on its own
particularities to provide the required behavious. Then
corpus_diff:has_net_changes just has to invoke
reporter_base::diff_has_net_changes on the reporter that is currently
in used.
The tests below verify that the exit code is zero when all the changes
between the test files are suppressed.
* include/abg-reporter.h ({reporter_base, default_reporter,
leaf_reporter}::diff_has_net_changes): Add new virtual function.
This breaks binary compatibility but should conserve source
compatibility.
* src/abg-default-reporter.cc
(default_reporter::diff_has_net_changes): Define new member
function.
* src/abg-leaf-reporter.cc (leaf_reporter::diff_has_net_changes):
Likewise.
* src/abg-comparison.cc (corpus_diff::has_net_changes): Invoke
reporter_base::diff_has_net_changes on the current reporter,
rather than trying to handle all the different kinds of reporters
here.
(corpus_diff::priv::apply_filters_and_compute_diff_stats): Add a
TODO to possibly delegate the implementation of this function to
the reporters.
* tests/data/Makefile.am: Add new test case files.
* tests/data/test-abidiff-exit/test-net-change-report0.txt:
Normal mode, nothing suppressed.
* tests/data/test-abidiff-exit/test-net-change-report1.txt:
Normal mode, everything suppressed.
* tests/data/test-abidiff-exit/test-net-change-report2.txt:
Leaf mode, nothing suppressed.
* tests/data/test-abidiff-exit/test-net-change-report3.txt:
Leaf mode, everything suppressions.
* tests/data/test-abidiff-exit/test-net-change-v0.c: Test file
* tests/data/test-abidiff-exit/test-net-change-v0.o: Test file
* tests/data/test-abidiff-exit/test-net-change-v1.c: Test file
* tests/data/test-abidiff-exit/test-net-change-v1.o: Test file
* tests/data/test-abidiff-exit/test-net-change.abignore: This
suppresses changes for all variables, functions and types in
the test files, except for the 'victim' function.
* tests/test-abidiff-exit.cc: Run new test cases.
