abidiff, abipkgdiff and abicompat now recognize a [suppress_file]
directive in suppression specifications. That directive instructs the
tool to avoid loading some binaries altogether.
This is the first directive that won't act on the result of the
comparison of two binaries. It actually acts earlier and prevents the
tool from loading some binaries altogether.
The directive looks like:
[suppress_file]
# Don't load any library named lib_private*.so
file_name_regexp = lib_private.*\\.so
This prevents the tool from loading (and thus comparing) any library
which name matches the pattern "lib_private*.so".
[suppress_file]
# Only load libraries name lib_public*.so
file_name_not_regexp = lib_public.*\\.so
This instructs the tool to only load (and compare) files which name
match the pattern "lib_public*.so".
* doc/manuals/libabigail-concepts.rst: Document the new
'suppress_file' directive.
* include/abg-suppression.h (file_suppression): Define new class.
(file_suppression_sptr): Define new typedef.
(is_file_suppression, file_is_suppressed): Declare new functions.
* src/abg-suppression.cc ():
(read_file_suppression, is_file_suppression, file_is_suppressed):
Define new functions.
(file_suppression::{file_suppression, suppresses_file,
~file_suppression}): Define new member functions.
* tools/abidiff.cc (main): If a suppression specification
suppresses one of the input files, then do not perform the
comparison.
* tools/abipkgdiff.cc (compare): If a suppression specification
suppresses a file that is to be compared, then do not perform the
comparison.
* tools/abicompat.cc (create_diff_context): New static function.
(perform_compat_check_in_normal_mode)
(perform_compat_check_in_weak_mode): Adjust to take a context in
parameter. Do not create a diff context here anymore, do not load
suppression files here either.
(main): Use the new create_diff_context to create a diff context
and initialize it, including loading suppression specifications.
If any suppression specification suppresses a file to load, then
do not load perform any compatibility checking. Adjust
invocations of perform_compat_check_in_weak_mode and
perform_compat_check_in_normal_mode to pass the diff context.
* tests/data/test-diff-suppr/test0-type-suppr-3.suppr: New test
input.
* tests/data/test-diff-suppr/test0-type-suppr-4.suppr: Likewise.
* tests/data/test-diff-suppr/test0-type-suppr-report-4.txt: Likewise.
* tests/data/test-diff-suppr/test0-type-suppr-5.suppr: Likewise.
* tests/data/test-diff-suppr/test0-type-suppr-report-5.txt:
Likewise.
* tests/data/test-diff-suppr/test0-type-suppr-6.suppr: Likewise.
* tests/data/test-diff-suppr/test0-type-suppr-report-6.txt:
Likewise.
* tests/data/test-diff-suppr/test0-type-suppr-report-7.txt:
Likewise.
* tests/test-diff-suppr.cc (in_out_specs): Use the new test
inputs.
* tests/data/test-abicompat/test0-fn-changed-1.suppr: New test
input.
* tests/data/test-abicompat/test0-fn-changed-report-3.txt:
Likewise.
* tests/test-abicompat.cc (in_out_specs):: Use the new test
inputs.
* tests/data/Makefile.am: Add the new test material to source
distribution.
