Hmm. I know we pass other stuff down, but is this really a good idea? It relies on the fact that the git that we test was built with the options from there. This assumptions breaks (with) GIT_TEST_INSTALLED, if not more. Basically, it may break as soon as we run the tests by other means than make, which is quite customary if you run single tests.

So, I think that would fix the biggest problem for afp-share users without disturbing others. It seems reasonable to me to do that unconditionnally. This can have security issues if you're trying to unlink a symlink, as chmod will dereference the symlink but unlink will not. Giving the file owner write permission may not be sufficient, as the user may be a member of a group with write access to the repo. A malicious user who also has access to the repo could force the current user to chmod an arbitrary file such that it had looser permissions. Ouch, indeed. I don't think that would be so problematic in practice (if the attacker has access to the repo, it's easier to write arbitrary code in hooks or config), but clearly we don't want to take the risk. So, the right solution should be stg like Junio's * in init-db.c, autoprobe by doing something like this: create a test file with 0444 permission bits; if (unlink(that test file)) { chmod(that test file, 0644); if (!unlink(that test file)) { broken_unlink = 1; git_config_set(core.brokenunlink, broken_unlink); } else { die(aaargh); } } But when core.brokenunlink is set, just use 0666 instead of 0444 as default mode for object files.

Question on shallow clones.
Hello, Very sorry if this has been explained before, I have been doing research past few weeks in spare time and have not found a good answer yet on the safety of doing something with git. Basically we have some repos with huge history, namely FreeBSD source and FreeBSD ports. In order to reduce the space in $repo/.git as well as speed up clone time we were thinking of doing a shallow clone of the repo with something like --depth 5000. I am wondering, if we such a thing, basically: # get a shallow mirror of let's say 5000 entries git clone --depth 5000 --mirror our-freebsd.git smaller-freebsd.git # move our current repo to a backup mv our-freebsd.git our-freebsd.git.backup # make shallow repo our primary mv smaller-freebsd.git our-freebsd.git Will we be able to push/pull from our new repo as if nothing happened? Will hashes remain the same? Can we in theory later do this: # merge branches from the github remote and push back to our-freebsd.git git clone /url/our-freebsd.git our-freebsd.git cd our-freebsd.git git remote add github https://github.com/freebsd/freebsd.git git fetch github # get from our-freebsd git checkout -b master origin/master # now merge in freebsd changes git merge --no-ff github/master git push origin HEAD Or will this break terribly?

On Friday, February 20, 2015 01:29:12 PM David Turner wrote: ... For a more general solution, perhaps a log of ref updates could be used. Every time a ref is updated on the server, that ref would be written into an append-only log. Every time a client pulls, their pull data includes an index into that log. Then on push, the client could say, I have refs as-of $index, and the server could read the log (or do something more-optimized) and send only refs updated since that index. Interesting idea, I like it. How would you make this reliable? It relies on updates being reliably recorded which would mean that you would have to ensure that any tool which touches the repo follows this convention. That is unfortunately a tough thing to enforce for most people. But perhaps, instead of logging updates, the server could log snapshots of all refs using an atomically increasing sequence number. Then missed updates do not matter, a sequence number is simplly an opaque handle to some full ref state that can be diffed against. The snapshots need not even be taken inline with the client connection, or with every update for this to work. It might mean that some extra updates are sent when they don't need to be, but at least they will be accurate. I know in the past similar ideas have been passed around, but they typically relied on the server keeping track of the state of each client. Instead, here we are talking about clients keeping track of state for a particular server. Clients already store info about remotes.

The ~/.git-credential-cache may be a bit harder, but the case of ~/.git-credentials should follow the same pattern as files for which this is already done. So, doing it by mimicking existing code shouldn't be too hard. But maybe that's me being optimistic ;-). As a person who did a significant number of GSoC 2014 micro-project reviews (as well as many actual GSoC reviews), I probably ought to weigh in and say that this may be too optimistic. In fact, most of the GSoC 2015 micro-project suggestions[1] seem far too large and involved. For 2014, most of the GSoC micro-projects were extremely simple, of the form replace starts_with() with skip_prefix(), yet most applicants still required three or four (or more) attempts to get it right (and some never did), even with extremely detailed hand-holding reviews at each step. (And, such reviews are quite time-consuming. I was allocating six to eight hours each day to those reviews, yet I couldn't keep up with all the submissions.) Although quite simple, many of the 2014 micro-projects[2] (particularly from Michael Haggerty) had a bit of a twist (or trick question) thrown in, requiring a tad more thought and effort than mere mechanical search-and-replace. That was useful because it helped identify potentially acceptable candidates more easily, however, that added twist was probably a good upper limit on difficulty for micro-projects. Another important aspect of 2014's micro-projects was that they could be accomplished with only very localized knowledge: that is, a student could read the logic of the one function being touched and learn enough to be successful. The micro-projects did not require global knowledge of Git internals or hours of research. The attitude in 2014 was that it was important for students to get a taste of what it is like working on the Git project and what would be expected of them as submitters, and for GSoC administrators and mentors to get a feel for the applicants by how they interacted with reviewers. By going through the review process on a project with high engineering standards, it also was hope that students would learn and benefit from the experience even if not selected. Extremely simple micro-projects (possibly with a twist) in the style of 2014's were more than sufficient to satisfy these goals, and were more than enough to consume significant reviewer time. The suggested 2015's micro-projects seem far in excess.

No, faulty thinking. Back to the whiteboard.. One version of vercmp() I read went like this: (1) Chomp the version strings into an alternate runs of digits and non-digits. e.g. 1.2.13 becomes 1, ., 2, . and 13 while 1.2.9 becomes 1, ., 2, . and 9. (2) Compare corresponding elements with strcmp() for runs of non-digits, and numerically for runs of digits. In the above example, up to the shared 1.2. would compare equal, and the final run of digits, 13 and 9 are compared numerically and we declare that 1.2.13 comes later. I think you can add a twist by introducing optionally this can appear substring. When there is such an optional substring defined, you also define if the side that lack the optional substring comes before or after the side that has one. For example, you declare [-]rc as optional substring that makes the owner of such a substring sort before others (call it optional negative substring) and comparing 2.0-rc12, 2.0-rc2 and 2.0: - 2.0 becomes 2, ., 0 and 2.0-rc2 becomes 2, ., 0, -rc, 2. Comparing them from left to right, the first difference is lack of anything (2.0 side runs out tokens) and -rc, which is marked as optional negative. Hence 2.0-rc2 sorts before 2.0 - 2.0-rc12 and 2.0-rc2 splits into tokens similarly. The first difference you see will be after you match -rc and -rc, which is 12 vs 2. Comparing them numerically, you know 2.0-rc12 comes later. You can define values to optional negatives and optional positives to express a more elaborate sort order e.g. 1.0-pre12 1.0-rc0 1.0 1.0-post1 even though -post does not have to be declared as optional positive. -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I added a hack to improve this locally inside Twitter: The client sends a bloom filter of shas that it believes that the server knows about; the server sends only the sha of master and any refs that are not in the bloom filter. The client uses its local version of the servers' refs as if they had just been sent. This means that some packs will be suboptimal, due to false positives in the bloom filter leading some new refs to not be sent. Also, if there were a repack between the pull and the push, some refs might have been deleted on the server; we repack rarely enough and pull frequently enough that this is hopefully not an issue. I wonder how efficient rsync is for transferring these refs: the client generates a file containing all refs, the server does the same with their refs, then the client rsync their file to the server..

Senior people will pull their changes, review, and if the changes are good, merge them and push the result to the project's central repository.

Interesting idea, I like it. How would you make this reliable?

That is unfortunately a tough thing to enforce for most people. I think it only truly relies on the server reliably updating its state on ref updates. Which of course the server will do because why would you let arbitrary processes write to your central git repo? (That is, most people use git in a roughly-centralized way, and if you turn on this config option, you promise to only do ref updates that write to the log).

In any case I've enabled it on both. Pack bitmaps matter most on the server side. What I was not sure was whether it helped the client side as well because you do rev-list on the client side for reachability test. But thinking again, I don't think enabling pack bitmaps on the client side helps much. The --not --all part in rev-list basically just traverses commits, not trees and objects (where pack bitmaps shine). The big problem here is --all which will go examine all refs. So big ref number problem again.. Even then with it enabled on both a git pull that pulls down just one commit on one branch is 13s. Trace attached at the end of the mail. haven't looked into it but there's got to be room for optimization there, surely it only has to do reachability checks for new refs, or could run in some I trust this remote not to send me corrupt data completely mode (which would make sense within a company where you can trust your main Git box). No, it's not just about trusting the server side, it's about catching data corruption on the wire as well. We have a trick to avoid reachability check in clone case, which is much more expensive than a fetch. Maybe we could do something further to help the fetch case _if_ reachability bitmaps don't help. Still, if that's indeed a big bottleneck what's the worst-case scenario here? That the local repository gets hosed? The server will still recursively validate the objects it gets sent, right? The server is under pressure to pack and send data fast so it does not validate as heavily as the client. When deltas are reused, only crc32 is verified. When deltas are generated, the server must unpack some objects for deltification, but I don't think it rehashes the content to see if it produces the same SHA-1. Single bit flips could go unnoticed.. I wonder if a better trade-off in that case would be to skip this in some situations and instead put something like git fsck in a cronjob. Either that or be optimistic, accept the pack (i.e. git-fetch returns quickly) and validate it in the background. If the pack is indeed good, you don't have to wait until validation is done. If the pack is bad, you would know after a minute or two, hopefully you can still recover from that point. -- Duy -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
Identifying user who ran “git reset” command
I came across a problem recently. One of the developers committed some changes in a branch. When he checked the branch log (git checkout branch; git log), the commit (say, abc) was showing up but when he checked the log for a file (git log file_name), which was part of the given commit (abc), the associated commit (abc) was not showing up; instead, an older commit id (say, xyz) was there. When the issue came to my notice, I tried using git log --follow file_name to check complete history of a file just to make sure whether the file was renamed to its current name. The output of git log --follow file_name was actually showing the commit id (abc) that was missing in the output of git log file_name command. On asking developer whether the file was renamed, i came to know that no renames were done ever for that file. This was confusing and i was stuck because i was not able to figure out what happened. Later, it turned out that another developer while pushing his code encountered merge conflict and instead of resolving it, he simply did a git reset . and the HEAD got shifted. Q.1) Is there any way i could have figured out about the git reset command that the other developer executed on his machine? FYI, i have admin access to Git. Q.2) Is there any way we can control such things from happening in future? I’m not sure whether this can be controlled using hook because this is not a ‘push’ command. It's something that's being done just before push. Please correct me if I’m mistaken. The biggest problem that I see here is that every developer has the rights to commit, which I feel is not right. I feel, even restricting it cannot be foolproof but it can certainly bring down such occurrences significantly.

Re: Git Scaling: What factors most affect Git performance for a large repo?
This is fantastic. I really appreciate all the answers. And it's great that I think I've sparked some general discussion that could lead somewhere too. Notes: I'm currently using 2.1.3. I'll move to 2.3.x I'm experimenting with git-annex to reduce repo size on disk. We'll see. I could remove all tags older than /n/ years old in the active repo and just maintain them in the historical repo. (We have quite a lot of CI-generated tags.) It sounds like that might improve performance. Questions: 1. Ævar : I'm a bit concerned by your statement that git rebases take about 1-2 s per commit. Does that mean that a git pull --rebase, if it is picking up say 120 commits (not at all unrealistic), could potentially take 4 minutes to complete? Or have I misinterpreted your comment. 2. I'd not heard about bitmap indexes before this thread but it sounds like they should help me. In limited searching I can't find much useful documentation about them. It is also not clear to me if I have to explicitly run git repack --write-bitmap-indexes or if git will automatically detect when they're needed; first experiments seem to indicate that I need to explicitly generate them. I assume that once the index is there, git will just use it automatically.

The most pathological case I've seen for git push is a branch with a single commit merged into the main development branch. As of Git 2.3.0, the performance regression here is fixed. Obviously, the speed of your network connection will affect this. Even at 30 MB/s, cloning several gigabytes of data takes time. Git tries hard to eliminate sending a lot of data, so if your developers keep reasonably up-to-date, the cost of establishing the connection will tend to dominate. I see pull and push times that are less than 2 seconds in most cases. * 'git commit'? (It is listed as slow in reference [3].) * 'git stautus'? (Slow again in reference 3 though I don't see it.) These can be slow with slow disks or over remote file systems. I recommend not doing that. I've heard rumbles that disk performance is better on Unix, but I don't use Windows so I can't say. You should keep your .gitignore files up-to-date to avoid enumerating untracked files. There's some work towards making this less of an issue. git blame can be somewhat slow, but it's not something I use more than about once a day, so it doesn't bother me that much.

The number of tags and branches individually is really less relevant than the total number of refs (tags, branches, remote branches, etc). Very large numbers of refs can impact performance on pushes and pulls due to the need to enumerate them all. * Binary objects in the repo that cause it to bloat in size [1] * Other factors? If you want good performance, I'd recommend the latest version of Git both client- and server-side. Newer versions of Git provide pack bitmaps, which can dramatically speed up clones and fetches, and Git 2.3.0 fixes a performance regression with large numbers of refs in non-shallow repositories.

This case is a bit more extreme; given the similarity of the two words, it is easy to use the wrong one. But I do not personally care much either way. As a side note, while writing out an explanation of --reference --dissociate recently, Michael (cc'd) and I noticed that it seems quite verbose to have to specify both options. By itself, --dissociate does nothing. It _could_ imply --reference (but right now complains that --reference was not provided and turns itself off). But if we were to have a single-option version of reference and dissociate, I do not think --dissociate is the best choice. By itself it does not mean much (dissociate from _what_?). I wonder if there is some better word that could become a synonym for --reference --dissociate. Maybe --borrow, but that does not necessarily carry the implication that the relationship ends as soon as the clone is done. What is really happening is that we are reusing objects in order to save bandwidth. Maybe --reuse-from would work? I dunno.

There are still some uses of int internally, but only for things that should obviously be small. And in any case we complain if there is overflow.

This one is not affected by how deep your repo's history is, or how wide your tree is, so should be quick.. Ah the number of refs may affect both git-push and git-pull. I think Stefan knows better than I in this area. I can tell you that this is a bit of a problem for us at Twitter. We have over 100k refs, which adds ~20MiB of downstream traffic to every push. I added a hack to improve this locally inside Twitter: The client sends a bloom filter of shas that it believes that the server knows about; the server sends only the sha of master and any refs that are not in the bloom filter. The client uses its local version of the servers' refs as if they had just been sent. This means that some packs will be suboptimal, due to false positives in the bloom filter leading some new refs to not be sent. Also, if there were a repack between the pull and the push, some refs might have been deleted on the server; we repack rarely enough and pull frequently enough that this is hopefully not an issue. We're still testing to see if this works. But due to the number of assumptions it makes, it's probably not that great an idea for general use. Good to hear that others are starting to experiment with solutions to this problem! I hope to hear more updates on this. I have a prototype of a simpler, and I believe more robust solution, but aimed at a smaller use case I think. On connecting, the client sends a sha of all its refs/shas as defined by a refspec, which it also sends to the server, which it believes the server might have the same refs/shas values for. The server can then calculate the value of its refs/shas which meet the same refspec, and then omit sending those refs if the verification sha matches, and instead send only a confirmation that they matched (along with any refs outside of the refspec). On a match, the client can inject the local values of the refs which met the refspec and be guaranteed that they match the server's values. This optimization is aimed at the worst case scenario (and is thus the potentially best case compression), when the client and server match for all refs (a refs/* refspec) This is something that happens often on Gerrit server startup, when it verifies that its mirrors are up-to-date. One reason I chose this as a starting optimization, is because I think it is one use case which will actually not benefit from fixing the git protocol to only send relevant refs since all the refs are in fact relevant here! So something like this will likely be needed in any future git protocol in order for it to be efficient for this use case. And I believe this use case is likely to stick around. With a minor tweak, this optimization should work when replicating actual expected updates also by excluding the expected updating refs from the verification so that the server always sends their values since they will likely not match and would wreck the optimization. However, for this use case it is not clear whether it is actually even worth caring about the non updating refs? In theory the knowledge of the non updating refs can potentially reduce the amount of data transmitted, but I suspect that as the ref count increases, this has diminishing returns and mostly ends up chewing up CPU and memory in a vain attempt to reduce network traffic. For a more general solution, perhaps a log of ref updates could be used. Every time a ref is updated on the server, that ref would be written into an append-only log. Every time a client pulls, their pull data includes an index into that log. Then on push, the client could say, I have refs as-of $index, and the server could read the log (or do something more-optimized) and send only refs updated since that index. -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
