T611: support for external definitions in the svn/subversion loader

Commits

rDLDSVN473fe145f4b7: ra: Add support for subversion external definitions

Summary

Subversion external definitions set on directories through the use of the
svn:externals property are now handled by the loader.

As with a svn export operation, externals will be attempted to be exported
in the paths they are defined. If an external is no longer valid (404),
the error will be ignored and the next one will be processed.

The implementation takes care of keeping the reconstructed repository
filesystem for a revision in sync with a svn export operation while
externals are added, updated or removed across revisions replay.

Related to T611

Depends on D6839

Test Plan

I have tested the implementation on numerous repositories from the list that
can be found in T611#75760.

Proceeding like this helped me to find edge cases that I did not think about
and fix them. I have added a dedicated test for each of them.

The implementation seems now pretty stable, I hope having covered all the weird
stuffs that can happen when dealing with external definitions in subversion.
Anyway, if some issue remains, they will be detected by the loader post_load
operation checking the reconstructed filesystem for the last loaded revision
is the same as the one obtained with a subversion export operation.

anlambert requested review of this revision.Jan 10 2022, 2:21 PM

A comment that should probably be addressed in a future diff:

If I understand it correctly, svn:externals checks out the latest version of the code at the time of the check out.

Does the incremental loader update the remote repo if the svn:externals property was not touched?
When archiving existing repositories, this would include the latest version of a remote repo in all revisions, even those older than the remote repo, right? The loader should probably assume both repositories have matching clocks, and use the last remote revision whose timestamp is lower than the the local revision, when building each local revision.

How do the tests check integrity of the results? (ie. there are the right revisions, the right files, etc.)

And a possible test to add:

remote commit 1, adds a file
local commit 2, adds an external on that file
remote commit 3, removes the file
local commit 4, does whatever

then check the content of directories of revisions 2 and 4

swh/loader/svn/ra.py
537	Why are they processed by a function called `close`?
566–568	are these directories removed? even if the loader crashes in this function. You could use the `dir` argument of `tempfile.mkdtemp()` to create them in a workdir you can clean at the end without keeping track of all paths
swh/loader/svn/svn.py
223–232

Does the incremental loader update the remote repo if the svn:externals property was not touched?

In incremental mode, the subversion loader first checks if the history got altered (meaning it checks if the last archived revision id corresponds to the one obtained from the current svn export of that revision)
and do a full reload of the repository if it is the case. So if an external remote repo got modified, the loader will detect it and will do a full reload with the external updated.

When archiving existing repositories, this would include the latest version of a remote repo in all revisions, even those older than the remote repo, right? The loader should probably assume both repositories have matching clocks, and use the last remote revision whose timestamp is lower than the the local revision, when building each local revision.

The official subversion is working that way, it will not try to match a revision date for an external without a revision number specified and will always export the last revision of the external.
So I did not implement such processing as we use subversion revision export as reference to check if the reconstructed filesystem is valid.

How do the tests check integrity of the results? (ie. there are the right revisions, the right files, etc.)

When the check_revision parameter of the loader is set to 1, after each revision replay the reconstructed filesystem
is compared to the one obtained with a subversion export operation on that revision. If the root directory hashes are
equal, we know that we correctly processed the directories and files.

And a possible test to add:

remote commit 1, adds a file
local commit 2, adds an external on that file
remote commit 3, removes the file
local commit 4, does whatever

Externals are only set on directories, test_loader_set_externals_with_versioned_file_overlap covers the case you defined.

anlambert added inline comments.Jan 12 2022, 1:22 PM

swh/loader/svn/ra.py
537	Official subversion client processes externals after the export of all the files local to the repository. The code in that diff does something similar by processing them when all local modifications to a versioned directory have been done when replaying the current revision, i.e. when the `close` method is called by the `svn_ra` API. Indeed, as externals can overlap with versioned files, we need to proceed like this.
566–568	I also noticed that yesterday, I have another diff coming that adds an external cache to avoid exporting them again and again when a same external URL is set on different directories. It will ensure that temp directories are properly removed at the end of the loading.

I see, thanks!

Rebase and ensure path of external root directory is stored in the external paths set.

swh/loader/svn/ra.py
566–568	D6925

LGTM, but I'd like an extra pair of eyes on it before landing

Optimize subversion export operation when dealing with externals: use the
origin URL as export parameter only if we know that some externals are
defined as relative to the repository URL and targets a path outside the
repository.

Indeed, when loading a repository from a remote dump mounted on the local
filesystem, it is better for performance to export a revision from that
local repository instead of a more costly export operation doing network
requests to the remote repository URL.

lgtm but I'm not sure i understood everything (code wise).

Let's land and check on staging that all is fine on the list you mentioned in the test plan?

I think it'd be good we start thinking about documenting our loaders.
Because for example, the svn:external is rather complex to follow through the code.
Definitely starting the svn:external with your great task comment [1]

668	what kind of error can arise here? Don't we want to log it?

    ra: Add support for subversion external definitions
    
    Subversion external definitions set on directories through the use of the
    svn:externals property are now handled by the loader.
    
    As with a svn export operation, externals will be attempted to be exported
    in the paths they are defined. If an external is no longer valid (404),
    the error will be ignored and the next one will be processed.
    
    The implementation takes care of keeping the reconstructed repository
    filesystem for a revision in sync with a svn export operation while
    externals are added, updated or removed across revisions replay.

lgtm but I'm not sure i understood everything (code wise).

Yes, dealing with externals when replaying revisions is quite complex.
The simplest solution would have been to export all revisions with the subversion client
instead of replaying them but as you know this is awful in terms of performance.

Let's land and check on staging that all is fine on the list you mentioned in the test plan?

Good idea, I will update the repos list in the task as new ones got processed by the loader
in production.

I think it'd be good we start thinking about documenting our loaders.
Because for example, the svn:external is rather complex to follow through the code.
Definitely starting the svn:external with your great task comment [1]

That's part of my roadmap for 2022 ;-)

swh/loader/svn/tests/test_loader.py
1915	They are invalid because the external URLs target non existing paths (404 simulation).

swh/loader/svn/ra.py
586	right
668	There is few chances that a versioned path overlaps an external but cases exist. We do not log the error here as it means there is no overlap between versioned path and external.

Remove not needed pass instruction
