commit 2af673b617c5d993127c37a2831202ff478f2135 Author: Valentin Lorentz <firstname.lastname@example.org> Date: Tue Nov 9 13:37:31 2021 +0100 Refactor package loaders to remove temporary revision objects commit 05496787809354552ea9ed0043d687acabf451d0 Author: Valentin Lorentz <email@example.com> Date: Mon Nov 8 13:39:17 2021 +0100 Document how each package loader populates fields. commit 89417bb072aade6b68402dbc10eaee61d98e9ae4 Author: Valentin Lorentz <firstname.lastname@example.org> Date: Fri Nov 5 13:18:01 2021 +0100 Make package loaders write releases instead of revisions The artifacts they load match the semantics of a Release, but we used Revisions so far because of technical details (we needed the 'metadata' field of Revision that Release lacks) that is no longer relevant (thanks to the metadata storage). Packages that were loaded by previous versions of the package loader (as revs) will be converted to releases. In order to avoid fetching them from the origin, the loader will look for an existing extid pointing to a revision (like it used to), fetch that revision, extract some fields (directory id, author, date, ...) and build a new release using this information. This commit is unfortunately very large because of all changes in tests, mostly just new hashes and renaming 'revision' to 'release' (and various abbreviations and capitalizations). The only meaningful changes are in swh/loader/package/tests/test_loader.py and swh/loader/package/loader.py. To keep this commit as short as possible, I did not yet change individual loaders to create releases: they still create revisions, but are converted by the base loader. The next commit will refactor them to remove this conversion layer. commit c0a98a5c4cfe4beac5c0b03bf61459d244b6f132 Author: Valentin Lorentz <email@example.com> Date: Thu Nov 4 17:58:37 2021 +0100 tests: Remove duplicate checks All the '*_missing' tests are already done automatically by check_snapshot (it recursively checks all objects are present in the storage). commit 2311ad9b365e23d1a3c532aa005e32db46bc06f3 Author: Valentin Lorentz <firstname.lastname@example.org> Date: Thu Nov 4 17:53:20 2021 +0100 tests: Hide utilities from stack traces They clutter the test output because pytest prints the whole code of the function raising the assertionerror. With this magic variable, the error is shown as if it was raised directly in the caller's body. commit 551c55ff04774b2c4e50e54f701c514064607f6a Author: Valentin Lorentz <email@example.com> Date: Thu Nov 4 15:49:45 2021 +0100 package loaders: Make test failures more helpful Some tests did the following: 1. build a snapshot 2. get the snapshot from the storage 3. compare it with the expected snapshot 4. get the origin visit from the storage and check it If the loader built a wrong snapshot, the test fails at step 2, and the only information displayed is that the expected snapshot id does not exist, which is very unhelpful. Instead, I reordered them as: 1, 4, 2, 3. This way, if a wrong snapshot is build by the loader, it is detected when comparing the visit, and pytest shows the two hashes. Then, the test can be modified to use the hash that is actually generated to show the actual snapshot. This is consistent with what was already done in the pypi loader. Additionally, I made the following changes: 1. always check stats last (because a difference in numbers is hardly actionable without testing other objects) 2. add a few more snapshot id checks in visits 3. deduplicated a hardcoded snapshot id. commit 89a0bfee48ca1663faddaa08b8fb3f163d5cfc6f Author: Valentin Lorentz <firstname.lastname@example.org> Date: Thu Oct 21 14:35:47 2021 +0200 deposit: Remove 'parent' deposit The parent is computed by the deposit as the revision of the latest deposit in the same origin before the current one. Therefore, it is redundant, as it can be recomputed from metadata + revision date. This is a preliminary change needed to make package loaders produce releases instead of revisions, as releases don't have parent relationships commit aeffe01a2b3918262e4bd715ea52c7d7da27807c Author: Valentin Lorentz <email@example.com> Date: Thu Nov 4 11:45:36 2021 +0100 opam: Write package definitions to the extrinsic metadata storage commit 18bbbae719fc9d165d5b543e54d449f5befc083a Author: Valentin Lorentz <firstname.lastname@example.org> Date: Thu Nov 4 11:43:53 2021 +0100 Add missing documentation for `get_metadata_authority`.
