When downloading bundles via the bundle-uri functionality, we only copy the
references from refs/heads into the refs/bundle space. I'm not sure why this
refspec is hardcoded to be so limited, but it makes the ref negotiation on
the subsequent fetch suboptimal, since it won't use objects that are
referenced outside of the current heads of the bundled repository.
This change to copy everything in refs/ in the bundle to refs/bundles/
significantly helps the subsequent fetch, since nearly all the references
are now included in the negotiation.

bundle-uri: copy all bundle references ino the refs/bundle space
This patch probably isn't meant for inclusion, but I wanted to see if
I'm crazy here or missing something.
It appears that the bundle-uri functionality has an issue with ref
negotiation. I hit this because I assumed all the objects I bundled
would be seen in the negotiation, but since only references under
refs/heads are copied to refs/bundles, they are the only ones that are
seen for negotiation, so it's quite inefficient.
I did several experiments trying to create a bundle where the subsequent
fetch was almost a no-op and it was frustratingly impossible and it took
me a while to figure out why it kept trying to get tons of other
objects.
Furthermore, when I bundled just a tag (thinking it would have most
reachable objects) it completely failed to work because there were no
refs/heads/ available for negotiation - so it downloaded a huge file and
then still started from scratch on the fetch.
However, if I copy all the refs in the bundle, it makes a big
difference.
Here are some benchmarks from the gitlab oss repo.
A normal clone pulls down 3,005,985 objects:

Then, I tried to bundle everything from a fresh clone, including all the
refs.
❯ git bundle create gitlab-base.bundle --all
This creates a 1.4G bundle, which I uploaded to a CDN and cloned again
with the bundle-uri:

(*) 181.98s user 40.23s system 110% cpu 3:20.89 total
Which is better from an "objects from the server" perspective, but still
has to download 959,773 objects, so 32% of the total. But it also takes
quite a lot longer, because it's redownloading most of those objects for
a second time.
If I apply this patch where I change the refspec for the bundle ref copy
from refs/heads/ to just refs/ and clone with this patched version, it's
much better:
❯ time ./git clone --bundle-uri=https://[cdn]/bundle/gitlab-base.bundle https://gitlab.com/gitlab-org/gitlab-foss.git gl3
Cloning into 'gl3'...

Updating files: 100% (59972/59972), done.
(*) 143.45s user 29.33s system 124% cpu 2:19.27 total
Now I'm only getting an extra 43k objects, so 1% of the original total,
and the entire operation is a bit faster as well.
I'm not sure if there is a downside here, it seems clearly how you would
want the negotiation to go. It ends up with way more refs under
refs/bundle (now there is refs/bundle/origin/master, etc) but that's
being polluted by the head refs anyhow, right?
Is this a reasonable change?

I am not sure what you mean by "being polluted by the head refs anyhow", but we should be equipped to deal with a repository with tons of local branches, so having the comparable number of remote-tracking branches instead of local branches now exposed in refs/bundle/remotes/* hierarchy should work equally as well, or we would have something we need to fix. So in principle I do not see a problem with this approach. The mapping used to be "refs/heads/foo" to "refs/bundles/foo", but now "refs/heads/foo" is mapped to "refs/bundles/heads/foo", so that you would presumably be mapping "refs/remotes/origin/master" to "refs/bundles/remotes/origin/master", right? I hope existing users are *not* looking at their resulting refs/bundles/ hierarchy and somehow assuming the original mapping. This is not something this "fix" changes, but unbundle_all_bundles() apparently is prepared to handle more than one bundles. I wonder what happens when multiple bundles expose the same branch pointing at different objects? The way I read unbundle_from_file() is that a new one overwrites the previous value, so even though we may have all unbundled many bundles, the objects from earlier bundles may lose their anchors, subject to be garbage-collected. Imagine creating a bundle with two refs, refs/heads and refs/remotes, and append that bundle as the last bundle of a bunch of bundles full of local and remote-tracking branches, that have populated refs/bundles/ hierarchy with tons of refs. Now the last bundle is unbundled, and these two phoney refs would nuke everything that used to be under refs/bundles/heads/* and refs/bundles/remotes/* left by unpacking previous bundles, right? > Is this a reasonable change?

This is an interesting case that I had not considered in the original implementation. The intention of the design is to avoid having the bundle URI fetch changing tag refs, especially annotated tags. Those tag updates are expected to be advertised in the "git fetch" output. It would probably be best to peel the tag refs to a commit and then create a fake branch for the bundle. >> Now I'm only getting an extra 43k objects, so 1% of the original total, >> and the entire operation is a bit faster as well. > > That makes all sense. > >> I'm not sure if there is a downside here, it seems clearly how you would >> want the negotiation to go.

The biggest question I had (and tried to get ahead of on the PR) is the use of a test to demonstrate what kind of bundle files cause this issue.

The issue for this and also for the other suggestion you have later on is that I'm not sure how this can be easily done with the bundle command. It seems like everyone would have to write some sort of script to create a special type of bundle so that all these objects are referenced in a way that makes the bundle-uri helper actually get most of the objects that are needed. Is there some option to rev-list that does this? Or are you saying it's better to write a script? > The biggest question I had (and tried to get ahead of on the PR) is > the use of a test to demonstrate what kind of bundle files cause this > issue.

I have written a test and I'll submit the new series in a minute, but I'm not sure what you mean by 'usable' in this context. Is there a situation where Git gets mad if there are annotated tags that aren't under refs/tags? I have done these test clones and nothing bad seems to happen having them in refs/bundle/tags/v1.0 that I notice, but I don't know how to write a test that specifically verifies that. > So I'm OK with relaxing this to be more flexible, but I'm not sure > why the bundles couldn't be created using "refs/heads/", possibly via > changing the ref names during bundle creation. So same point here. I think the bundle-uri functionality isn't particularly effective if the creation of the bundle needs special scripts to create in a way that is expected. One other approach would be to add an option to `git bundle` that does this sanitization (unpeeling things into fake branch heads), like some `--bundle-for-uri`, but I feel like just using `--all` and having the clone handle it in the way I proposed might be much simpler and more usable. We could also immediately delete everything under `refs/bundle/tags` after the fetch if we don't like them there, but still having them be available for the fetch negotiation. I'll send a new series with the existing tests updated to look for `refs/bundle/heads/*` instead of `refs/bundle/*` and adding a very simple test to see that the tags were unpacked as the next step.

Can it be some brittleness Derrick is worried about auto-following of tags during future "git fetch"? You store a tag that a regular fetch may want to store at refs/tags/v1.0 in refs/bundles/tags/v1.0 taken from the bundle, and then a later fetch may advance the history based on you extracted from the bundle---without having to run an explicit "git fetch --tags" or "git fetch origin v1.0", would we ever obtain "refs/tags/v1.0" with only the usual auto-following when we have the same tag elsewhere? In any case, instead of me speculating, I'd prefer to hear from Derrick, who is a lot more familiar with the mechanism under discussion, what the issues are that we want to limit ourselves to local branches.

My thinking here is similar to the prefetch maintenance task: we want users who run "git fetch [origin]" to see the refs that are being updated by that action in the normal foreground messages. This includes new tag messages, such as in my local copy of the Git repository: $ git fetch origin remote: Enumerating objects: 186, done. remote: Counting objects: 100% (168/168), done. remote: Compressing objects: 100% (51/51), done. remote: Total 186 (delta 120), reused 162 (delta 117), pack-reused 18 (from 2) Receiving objects: 100% (186/186), 118.04 KiB | 10.73 MiB/s, done.

I'm not sure why this refspec is hardcoded to be so limited, but it makes the ref negotiation on the subsequent fetch suboptimal, since it won't use objects that are referenced outside of the current heads of the bundled repository. This change to copy everything in refs/ in the bundle to refs/bundles/ significantly helps the subsequent fetch, since nearly all the references are now included in the negotiation.

I've not used the bundle-uri feature but this change sounds sensible. The refspec that's changed here is documented in Documentation/technical/bundle-uri.adoc (see item 2 in the list under "Cloning with Bundle URIs") so we should update that. That document as says this refspec is configurable but it seems that was never implemented so it would be nice to fix that at the same time.

I think we should be testing that all of the refs we expect to have made it over actually did so. This diff (applied on top of your series) does that: --- 8< --- diff --git a/t/t5558-clone-bundle-uri.sh b/t/t5558-clone-bundle-uri.sh index b1276ba295..9b211a626b 100755 --- a/t/t5558-clone-bundle-uri.sh +++ b/t/t5558-clone-bundle-uri.sh @@ -128,13 +128,12 @@ test_expect_success 'create bundle with tags' ' test_expect_success 'clone with tags bundle' ' git clone --bundle-uri="clone-from-tags/ALL.bundle" \ clone-from-tags clone-tags-path && - git -C clone-tags-path for-each-ref --format="%(refname)" >refs && - grep "refs/bundles/tags/" refs >actual && - cat >expect <<-\EOF && - refs/bundles/tags/A - refs/bundles/tags/B - refs/bundles/tags/tag-A - EOF + + git -C clone-from-tags for-each-ref --format="%(refname:lstrip=1)" \ + >expect && + git -C clone-tags-path for-each-ref --format="%(refname:lstrip=2)" \ + refs/bundles >actual && + test_cmp expect actual ' --- >8 --- While writing the above, I wasn't quite sure how to follow the test setup.

I had a bit of a time figuring out the testing structure enough to even write the tests I did. I updated my series with Taylor's patch and I'll resubmit it. Beyond that I may need someone else to help me with more complicated testing needs if more work is to be done.

After all the point of this series is to create refs under > refs/bundles for all the refs in the bundle. The really interesting case that the original behaviour could have been "working around existing bugs" would be - prepare an annotated tag. - include that annotated tag in the bundle specified by the bundle-uri feature (whose SOLE purpose is to speed up the main part of the tranfer, WITHOUT affecting the resulting remote tracking refs and global tag namespace). - prepare a repository that uses that bundle as bundle-uri when getting cloned (let's call it the 'origin' repository). It probably is convenient if you make this a repository separate from where you prepared the bundle above. Make sure that this repository does *not* (yet) have that annotated tag. - clone from the 'origin' repository with bundle-uri feature. The annotated tag would be held under refs/bundles/tags/ hierarchy but that is *not* the interesting part. Make sure that the annotated tag does *not* appear in refs/tags/ hierarchy of the clone, since it does not exist (yet) at the 'origin' repository. - Now add that annotated tag to the 'origin' repository. - fetch from the 'origin' repository again, with the default configuration (i.e. allowing "tags follow when commits they reference are fetched" feature to kick in). As the annotated tag appears in refs/tags/ of the 'origin' repository, the commit pointed at by that annotated tag now appears in one of its branches, and the history leading to that commit (and possibly others) are transferred to refs/remotes/origin/* remote-tracking branches, the tag-following feature should kick in and copy the annotated tag in refs/tags/ hierarchy as well. The interesting part to verify is that in the cloned repository the annotated tag does not appear in refs/tags/ immediately after cloneing, but does appear there after the 'origin' is updated to have the tag under refs/tags/ and then fetch ^ permalink raw reply [flat|nested] 37+ messages in thread

I'm not sure why this refspec is hardcoded to be so limited, but it makes the ref negotiation on the subsequent fetch suboptimal, since it won't use objects that are referenced outside of the current heads of the bundled repository. This change to copy everything in refs/ in the bundle to refs/bundles/ significantly helps the subsequent fetch, since nearly all the references are now included in the negotiation. The update to the bundle-uri unbundling refspec puts all the heads from a bundle file into refs/bundle/heads instead of directly into refs/bundle/ so the tests also need to be updated to look in the new heirarchy.

I'm seriously sorry for the coda on this updated commit message. I was testing out a different thing for something totally unrelated and was just adding random text to the end of the message that made me laugh. I didn't mean to submit this as the message after coming back to it after a few weeks. I promise this wasn't on purpose. (I'm not very good at Git) Related to the code change though, there was a comment that the message didn't match the patch somehow, but I'm afraid I don't understand how. Other than the cheeky mistaken addendum, it seems to me that the message still describes the new tests, no?

I'm not sure why this refspec is hardcoded to be so limited, but it makes the ref negotiation on the subsequent fetch suboptimal, since it won't use objects that are referenced outside of the current heads of the bundled repository. This change to copy everything in refs/ in the bundle to refs/bundles/ significantly helps the subsequent fetch, since nearly all the references are now included in the negotiation. The update to the bundle-uri unbundling refspec puts all the heads from a bundle file into refs/bundle/heads instead of directly into refs/bundle/ so the tests also need to be updated to look in the new heirarchy.

I'm not sure why this refspec is hardcoded to be so limited, but it makes the ref negotiation on the subsequent fetch suboptimal, since it won't use objects that are referenced outside of the current heads of the bundled repository. This change to copy everything in refs/ in the bundle to refs/bundles/ significantly helps the subsequent fetch, since nearly all the references are now included in the negotiation. The update to the bundle-uri unbundling refspec puts all the heads from a bundle file into refs/bundle/heads instead of directly into refs/bundle/ so the tests also need to be updated to look in the new heirarchy.

I'm not sure why this refspec is hardcoded to be so limited, but it makes the ref negotiation on the subsequent fetch suboptimal, since it won't use objects that are referenced outside of the current heads of the bundled repository. This change to copy everything in refs/ in the bundle to refs/bundles/ significantly helps the subsequent fetch, since nearly all the references are now included in the negotiation. The update to the bundle-uri unbundling refspec puts all the heads from a bundle file into refs/bundle/heads instead of directly into refs/bundle/ so the tests also need to be updated to look in the new heirarchy.
