From 971f0ba9d6d332fe98e4d962f63edbfb16077e83 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 5 Nov 2025 14:16:12 +0000 Subject: [PATCH] test: Add comprehensive test coverage for PlaylistSource and ResamplingNode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit adds extensive unit and integration tests for the audio pipeline components that were previously untested. ## ResamplingNode Tests (pmoaudio/src/nodes/resampling_node.rs) - Added 7 test functions covering: - Helper function tests: extract_channels_i16/i24 - Reconstruction tests: reconstruct_chunk_i16/i24 - Logic tests: passthrough when sample rate matches - Async tests: verify sync markers pass through unchanged - Integration test: actual 44.1kHz → 48kHz resampling ## PlaylistSource Tests (pmoaudio-ext/src/sources/playlist_source.rs) - Added 10 test functions covering: - Stream validation: valid/invalid channel counts and bit depths - PCM conversion: bytes_to_segment for I16/I24/I32 formats - Mono/stereo handling: verify channel duplication - Error handling: unsupported bit depth rejection - Type safety: compilation verification ## Bug Fixes - Fixed imports: Node and NodeLogic moved from nodes to pipeline module - Fixed AudioCache import: use pmoaudiocache::Cache with alias - Fixed API calls in ResamplingNode: - BitDepth::from_audio_chunk() → match pattern - .stereo() → .get_frames() - .to_i32() → .as_i32() for I24 - .sample_rate() → .get_sample_rate() ## Documentation - Added INSTALL_LIBSOXR.md with detailed installation instructions - Documents local libsoxr installation without sudo privileges - Provides troubleshooting guide for build and test environments All tests pass successfully (17 tests total: 7 ResamplingNode + 10 PlaylistSource). --- .gitignore | 3 +- INSTALL_LIBSOXR.md | 137 +++++++++++ pmoaudio-ext/src/sources/playlist_source.rs | 259 +++++++++++++++++++- pmoaudio/src/nodes/resampling_node.rs | 196 +++++++++++++++ 4 files changed, 591 insertions(+), 4 deletions(-) create mode 100644 INSTALL_LIBSOXR.md diff --git a/.gitignore b/.gitignore index 05ec847c..08ebb80f 100644 --- a/.gitignore +++ b/.gitignore @@ -36,4 +36,5 @@ all.txt pmo_src.txt upmpdcli/ /*.xml -test_upnp \ No newline at end of file +test_upnp*.cargo/ +.cargo/ diff --git a/INSTALL_LIBSOXR.md b/INSTALL_LIBSOXR.md new file mode 100644 index 00000000..2192d311 --- /dev/null +++ b/INSTALL_LIBSOXR.md @@ -0,0 +1,137 @@ +# Installation de libsoxr sans droits sudo + +Ce document explique comment installer libsoxr localement sans privilèges administrateur, nécessaire pour compiler `pmoaudio` avec le support de resampling. + +## Contexte + +Le crate `soxr` (utilisé par `ResamplingNode`) nécessite la bibliothèque système `libsoxr`.

Télécharger les packages .deb + +```bash +cd ~/.local +apt-get download libsoxr-dev libsoxr0 +``` + +Cela télécharge les fichiers `.deb` sans les installer système-wide. + +### 2.
