commit 6afc8b39601c0f93375bcf37daa1b8a3d5bf242a
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Mon Jun 28 19:21:58 2021 +0200

commit 23184e7de91d7e60577ce730868098b91a72b1d1
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Mon Jun 28 14:37:50 2021 +0200

    Move `ProvenanceBackend` implementation to a separate file

commit f32475952907452f3dbe3d51be9433aa854413bf
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Mon Jun 28 14:28:32 2021 +0200

    Rework `ProvenanceInterface` as discussed during backend design
    
    Add `ProvenanceResult` class to be returned by `content_find_first` and
    `content_find_all` methods. Rename some methods. Improve type annotations.

commit ad860db9bfeff7f276b3e356c9e21cb57cafc4c2

Date:   Thu Jun 24 16:31:16 2021 +0200

    Add tests for history graph topology

commit 37ac81faf15a32c4471a3c4ee5140bcb9bf57178
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Thu Jun 24 16:10:38 2021 +0200

    Fix database queries related to the origin-revision layer
    
    This required allowing null dates in the `revision` table so that revision can be added
    by the origin-revision layer algorithm but not recognized as already processed by the
    revision-content layer. Revision and origin entries are now inserted in the database
    prior to inserting rows to revision_in_origin and revision_before_revision relations,
    so that internal ids are properly resolved.

Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Fri Jun 25 13:38:26 2021 +0200

    Add test to compare both ArchiveInterface implementations
    
    Improve documentation of the interface and complete pending TODO's.

Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Thu Jun 24 16:05:24 2021 +0200

    Refactor ArchiveInterface to fit origin-revision layer needs
    
    Replace `revision_get` method by `revision_get_parents` returning an iterable of
    parents' ids only, instead of a swh.model.model.Revision object.

commit df69a9e57692ed9d4d870c295a21b3ac187d7b9c
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>

    Use `Sha1Git` type to explicitly state the kind of identifiers
    
    Previous occurrences of `bytes` and `Sha1` are not correctly using `Sha1Git`.
    Also, some bytes conversion methods were replaced by their counterparts in
    the swh.model.hashutil module.

commit 2304647745e79308b72978ba3a9141f3e6f844f8
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Mon Jun 28 19:21:58 2021 +0200

    Add `ProvenanceStorageInterface` as discussed during backend design
    
    Rework backend-related classes to properly use the new interface.
    Adapt tests to the new structure as well.

commit e25122d2e47de942a772164e9f1a60f425c87d97
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Mon Jun 28 14:37:50 2021 +0200

    Move `ProvenanceBackend` implementation to a separate file

commit b7678a341da72587cc48848f5a72f65861f892af
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Mon Jun 28 14:28:32 2021 +0200

    Rework `ProvenanceInterface` as discussed during backend design
    
    Add `ProvenanceResult` class to be returned by `content_find_first` and
    `content_find_all` methods. Rename some methods. Improve type annotations.

commit 7a59ff712bb8b5ae22e6f016475d03317c27b64a
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Thu Jun 24 16:31:16 2021 +0200

    Add tests for history graph topology

commit 3171ae2f129df433689fd22e32c8eeebf7af4171
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Thu Jun 24 16:10:38 2021 +0200

    Fix database queries related to the origin-revision layer
    
    This required allowing null dates in the `revision` table so that revision can be added
    by the origin-revision layer algorithm but not recognized as already processed by the
    revision-content layer. Revision and origin entries are now inserted in the database
    prior to inserting rows to revision_in_origin and revision_before_revision relations,
    so that internal ids are properly resolved.

commit 6736f6068280f167df5616681dee9ad67b2b7dbd
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Fri Jun 25 13:38:26 2021 +0200

Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Thu Jun 24 16:05:24 2021 +0200

    Refactor `ArchiveInterface` to fit origin-revision layer needs
    
    Replace `revision_get` method by `revision_get_parents` returning an iterable of
    parents' ids only, instead of a swh.model.model.Revision object.

commit df69a9e57692ed9d4d870c295a21b3ac187d7b9c
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Wed Jun 23 20:00:40 2021 +0200

    Use `Sha1Git` type to explicitly state the kind of identifiers
    
    Previous occurrences of `bytes` and `Sha1` are not correctly using `Sha1Git`.
    Also, some bytes conversion methods were replaced by their counterparts in
    the swh.model.hashutil module.

commit fa22dc902781e30e46823030681f003983cc6d6e
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>

commit d45d6ff9e9317ecfe38d584df7297c548b654d28
Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Thu Jun 24 16:10:38 2021 +0200

    Fix database queries related to the origin-revision layer
    
    This required allowing null dates in the `revision` table so that revision can be added
    by the origin-revision layer algorithm but not recognized as already processed by the
    revision-content layer. Revision and origin entries are now inserted in the database
    prior to inserting rows to revision_in_origin and revision_before_revision relations,
    so that internal ids are properly resolved.

Author: Andres Ezequiel Viso <aeviso@softwareheritage.org>
Date:   Thu Jun 24 16:05:24 2021 +0200

    Refactor `ArchiveInterface` to fit origin-revision layer needs
    
    Replace `revision_get` method by `revision_get_parents` returning an iterable of
    parents' ids only, instead of a swh.model.model.Revision object.

Date:   Wed Jun 23 20:00:40 2021 +0200

    Use `Sha1Git` type to explicitly state the kind of identifiers
    
    Previous occurrences of `bytes` and `Sha1` are now correctly using `Sha1Git`.
    Also, some bytes conversion methods were replaced by their counterparts in
    the swh.model.hashutil module.

douardda added inline comments.
swh/provenance/__init__.py
29

it would be best to have the removal of this bwcompat support (and deprecation warning) in a dedicated revision, but meh.

swh/provenance/backend.py
71–94

This could probably be factorized. Also are you sure you want to write the whole content of the cache in the logs? Might generate a lots of logs...

118–149

Same here, this could be factorized (looping on the 3 entity types).

221–230

I'm not sure I get this chunk of code. What does it do exactly? What's the empty list for? Is it the start value of the sum() function? (If so it's much better to use named argument, much easier to understand).

But if I get this right, a more pythonic way (?) could be:

cache = self.cache["revision_before_revision"]
rbr_data = itertools.chain(*(( (prev, next, None) 
                     for next in cache[prev] )
                          for prev in cache ))
340–342

The explicit bool cast is a bit weird here. Since the methods returns a set(), I would find it more readable to compare the results with an empty set or use the length().

swh/provenance/postgresql/provenancedb_base.py
24–26

For a oneliner like this, using an intermediate local variable seems a bit overkill to me.

31–33

same as above

81

the "old ways" of doing this looks more readable to me:

", ".join(["%s"] * len(sha1s))

I've made several small comments / nitpicks, fell free to address them or not.

This revision is now accepted and ready to land.Jul 2 2021, 4:32 PM

I think this comment is out of place. What empty list do you mean?

it's actually more cryptic to me... but I guess that's subjective
