Pull request overview
Adds a new regression test to validate that OggFLACPassthroughCodec::initialize() fails gracefully when FLAC initialization fails, and updates test link dependencies to ensure the new test builds.
Changes:
- Added
testOggFLACExceptionHandling()to exercise FLAC passthrough initialization failure behavior. - Updated
tests/Makefile.amLDADD entries to include broader codec/common codec link sets for Ogg-related tests.

| File | Description |
|---|---|
| tests/test_ogg_error_handling.cpp | Adds a new test case that expects OggFLACPassthroughCodec::initialize() to return false under invalid FLAC stream parameters. |
| tests/Makefile.am | Adjusts test link dependencies (notably adding FULL_CODEC_LIBS for test_ogg_error_handling and simplifying test_ogg_fuzzing linkage). |

This test is named/worded as “exception handling”, but with info.sample_rate = 2000000 the native FLAC codec fails via explicit parameter validation and returns false (e.g., src/codecs/flac/NativeFLACCodec.cpp:272-279) rather than throwing. Also, the comment about “NativeFLACCodec … might throw an exception” is misleading because FLACCodec::initialize() already catches std::exception and returns false (src/codecs/flac/NativeFLACCodec.cpp:115-122). If the intent is to cover OggFLACPassthroughCodec’s catch (...) path (src/codecs/OggCodecs.cpp:67-72), consider adjusting the test to actually trigger an exception (or rename/reword it to focus on initialization failure handling rather than exception handling).

test_ogg_error_handling_LDADD now adds $(FULL_CODEC_LIBS) but still keeps libtest_utilities.a at the front. Since FULL_CODEC_LIBS already includes libtest_utilities.a (tests/Makefile.am:188-191), this is redundant and makes the link line significantly heavier than needed. Consider either removing the standalone libtest_utilities.a here, or (preferably) linking only the minimal codec archive(s) required for OggFLACPassthroughCodec instead of pulling in the full codec test dependency set.

🎯 What: Improved test coverage for
OggFLACPassthroughCodec::initializeinsrc/codecs/OggCodecs.cppby validating the behavior when the underlying codec throws an exception or fails initialization due to malformed data.📊 Coverage: Added
testOggFLACExceptionHandlingtotests/test_ogg_error_handling.cppwhich simulates an invalid sample rate for FLAC initialization, verifying the outer codec correctly returns false and handles the failure gracefully. Updatedtests/Makefile.amto link necessary dependencies (FULL_CODEC_LIBSandCOMMON_CODEC_LIBS) for proper test compilation.✨ Result: Enhanced error handling test coverage for Ogg demuxing.
