The summary is: the current default of 250 doesn't save much space, and costs CPU. It's not a good tradeoff. Read on for details. The "--aggressive" flag to git-gc does three things: 1. use "-f" to throw out existing deltas and recompute from scratch 2. use "--window=250" to look harder for deltas 3. use "--depth=250" to make longer delta chains Items (1) and (2) are good matches for an "aggressive" repack. They ask the repack to do more computation work in the hopes of getting a better pack. You pay the costs during the repack, and other operations see only the benefit. Item (3) is not so clear. Allowing longer chains means fewer restrictions on the deltas, which means potentially finding better ones and saving some space. But it also means that operations which access the deltas have to follow longer chains, which affects their performance. So it's a tradeoff, and it's not clear that the tradeoff is even a good one. The existing "250" numbers for "--aggressive" come originally from this thread: http://public-inbox.org/git/alpine.LFD.0.9999.0712060803430.13796@woody.linux-foundation.org/ where Linus says: So when I said "--depth=250 --window=250", I chose those numbers more as an example of extremely aggressive packing, and I'm not at all sure that the end result is necessarily wonderfully usable. It's going to save disk space (and network bandwidth - the delta's will be re-used for the network protocol too!), but there are definitely downsides too, and using long delta chains may simply not be worth it in practice. There are some numbers in that thread, but they're mostly focused on the improved window size, and measure the improvement from --depth=250 and --window=250 together. E.g.: http://public-inbox.org/git/9e4733910712062006l651571f3w7f76ce64c6650dff@mail.gmail.com/ talks about the improved run-time of "git-blame", which comes from the reduced pack size. But most of that reduction is coming from --window=250, whereas most of the extra costs come from --depth=250. There's a link in that thread showing that increasing the depth beyond 50 doesn't seem to help much with the size: https://vcscompare.blogspot.com/2008/06/git-repack-parameters.html but again, no discussion of the timing impact. In an earlier thread from Ted Ts'o which discussed setting the non-aggressive default (from 10 to 50): http://public-inbox.org/git/20070509134958.GA21489%40thunk.org/ we have more numbers, with the conclusion that going past 50 does not help size much, and hurts the speed of normal operations. So from that, we might guess that 50 is actually a sweet spot, even for aggressive, if we interpret aggressive to "spend time now to make a better pack". It is not clear that "--depth=250" is actually a better pack. It may be slightly _smaller_, but it carries a run-time penalty. Here are some more recent timings I did to verify that. They show three things: - the size of the resulting pack (so disk saved to store, bandwidth saved on clones/fetches) - the cost of "rev-list --objects --all", which shows the effect of the delta chains on trees (commits typically don't delta, and the command doesn't touch the blobs at all) - the cost of "log -Sfoo", which will additionally access each blob All cases were repacked with "git repack -adf --depth=$d --window=250" (so basically, what would happen if we tweaked the "gc --aggressive" default depth). The timings are all wall-clock best-of-3. The machine itself has plenty of RAM compared to the repositories (which is probably typical of most workstations these days), so we're really measuring CPU usage, as the whole thing will be in disk cache after the first run. The core.deltaBaseCacheLimit is at its default of 96MiB. It's possible that tweaking it would have some impact on the tests, as some of them (especially "log -S" on a large repo) are likely to overflow that. But bumping that carries a run-time memory cost, so for these tests, I focused on what we could do just with the on-disk pack tradeoffs. Each test is done for four depths: 250 (the current value), 50 (the current default that tested well previously), 100 (to show something on the larger side, which previous tests showed was not a good tradeoff), and 10 (the very old default, which previous tests showed was worse than 50). Here are the numbers for linux.git: depth | size | % | rev-list | % | log -Sfoo | % -------+-------+-------+----------+--------+-----------+------- 250 | 967MB | n/a | 48.159s | n/a | 378.088 | n/a 100 | 971MB | +0.4% | 41.471s | -13.9% | 342.060 | -9.5% 50 | 979MB | +1.2% | 37.778s | -21.6% | 311.040s | -17.7% 10 | 1.1GB | +6.6% | 32.518s | -32.5% | 279.890s | -25.9% and for git.git: depth | size | % | rev-list | % | log -Sfoo | % -------+-------+-------+----------+--------+-----------+------- 250 | 48MB | n/a | 2.215s | n/a | 20.922s | n/a 100 | 49MB | +0.5% | 2.140s | -3.4% | 17.736s | -15.2% 50 | 49MB | +1.7% | 2.099s | -5.2% | 15.418s | -26.3% 10 | 53MB | +9.3% | 2.001s | -9.7% | 12.677s | -39.4% You can see that that the CPU savings for regular operations improves as we decrease the depth. The savings are less for "rev-list" on a smaller repository than they are for blob-accessing operations, or even rev-list on a larger repository. This may mean that a larger delta cache would help (though setting core.deltaBaseCacheLimit by itself doesn't). But we can also see that the space savings are not that great as the depth goes higher. Saving 5-10% between 10 and 50 is probably worth the CPU tradeoff. Saving 1% to go from 50 to 100, or another 0.5% to go from 100 to 250 is probably not.

|\ \ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even when "git pull --rebase=preserve" (and the underlying "git rebase --preserve") can complete without creating any new commit (i.e. fast-forwards), it still insisted on having a usable ident information (read: user.email is set correctly), which was less than nice. As the underlying commands used inside "git rebase" would fail with a more meaningful error message and advice text when the bogus ident matters, this extra check was removed. * jk/rebase-i-drop-ident-check: rebase-interactive: drop early check for valid ident

This is convenient, because it means that we abort the operation before even beginning (rather than just complaining that we are unable to pick a particular commit). However, it does the wrong thing when the rebase does not actually need to generate any new commits (e.g., a fast-forward with no commits to pick, or one where the base stays the same, and we just pick the same commits without rewriting anything). In this case it may complain about the lack of ident, even though one would not be needed to complete the operation. This may seem like mere nit-picking, but because interactive rebase underlies the "preserve-merges" rebase, somebody who has set "pull.rebase" to "preserve" cannot make even a fast-forward pull without a valid ident, as we bail before even realizing the fast-forward nature. This commit drops the extra ident check entirely. This means we rely on individual commands that generate commit objects to complain. So we will continue to notice and prevent cases that actually do create commits, but with one important difference: we fail while actually executing the "pick" operations, and leave the rebase in a conflicted, half-done state. In some ways this is less convenient, but in some ways it is more so; the user can then manually commit or even "git rebase --continue" after setting up their ident (or providing it as a one-off on the command line).

But since git_config() is backed by a cache these days, it's possible that the call will not actually touch the filesystem at all; we need to tell it that something has changed behind the scenes. Note that we also need to reset the shared_repository config. At first glance, it seems like this should probably just be folded into git_config_clear(). But unfortunately that is not quite right. The shared repository value may come from config, _or_ it may have been set manually. So only the caller who knows whether or not they set it is the one who can clear it (and indeed, if you _do_ put it into git_config_clear(), then many tests fail, as we have to clear the config cache any time we set a new config variable). There are three tests here. The first two actually pass already, though it's largely luck: they just don't happen to actually read any config before we enter the new repo. But the third one does fail without this patch; we look at core.sharedrepository while creating the directory, but need to make sure the value from the template config overrides it.

It gets the latter by calling git_pathdup(), which in turn calls get_git_dir(). If we haven't set up the git repository yet, this may simply return ".git", and we will look at ".git/config". This seems like it would be helpful (presumably we haven't set up the repository yet, so it tries to find it), but it turns out to be a bad idea for a few reasons: - it's not sufficient, and therefore hides bugs in a confusing way. Config will be respected if commands are run from the top-level of the working tree, but not from a subdirectory. - it's not always true that we haven't set up the repository _yet_; we may not want to do it at all. For instance, if you run "git init /some/path" from inside another repository, it should not load config from the existing repository. - there might be a path ".git/config", but it is not the actual repository we would find via setup_git_directory(). This may happen, e.g., if you are storing a git repository inside another git repository, but have munged one of the files in such a way that the inner repository is not valid (e.g., by removing HEAD). We have at least two bugs of the second type in git-init, introduced by ae5f677 (lazily load core.sharedrepository, 2016-03-11). It causes init to use git_configset(), which loads all of the config, including values from the current repo (if any). This shows up in two ways: 1. If we happen to be in an existing repository directory, we'll read and respect core.sharedrepository from it, even though it should have no bearing on the new repository. A new test in t1301 covers this. 2. Similarly, if we're in an existing repo that sets core.logallrefupdates, that will cause init to fail to set it in a newly created repository (because it thinks that the user's templates already did so). A new test in t0001 covers this. We also need to adjust an existing test in t1302, which gives another example of why this patch is an improvement. That test creates an embedded repository with a bogus core.repositoryformatversion of "99". It wants to make sure that we actually stop at the bogus repo rather than continuing upward to find the outer repo. So it checks that "git config core.repositoryformatversion" returns 99. But that only works because we blindly read ".git/config", even though we _know_ we're in a repository whose vintage we do not understand. After this patch, we avoid reading config from the unknown vintage repository at all, which is a safer choice. But we need to tweak the test, since core.repositoryformatversion will not return 99; it will claim that it could not find the variable at all.

This works because git_config() blindly reads ".git/config" even if we have not configured a repository. This means that test-config won't work from a subdirectory, though since it's just a helper for the test scripts, that's not a big deal. More important is that the behavior of git_config() is going to change, and we want to make sure that t1308 continues to work. We can just use setup_git_directory(), and not the gentle form; there's no point in being flexible, as it's just a helper for the tests.

When we ask git_config() to look for values like core.pager, it doesn't know where to find the repo-level config, and will blindly examine ".git/config" if it exists. That's why t7006 shows that many pager-related features happen to work from the top-level of a repository, but not from a subdirectory. This patch pulls that ".git/config" hack explicitly into the pager code. There are two reasons for this: 1. We'd like to clean up the git_config() behavior, as looking at ".git/config" when we do not have a configured repository is often the wrong thing to do. But we'd prefer not to break the pager config any worse than it already is. 2. It's one very tiny step on the road to ultimately making the pager config work consistently. If we eventually get an equivalent of setup_git_directory() that _just_ finds the directory and doesn't chdir() or set up any global state, we could plug it in here (instead of blindly looking at ".git/config").

But to do so, we use the git_default_config() callback, which loads many other values. Ordinarily it isn't a big deal to load this config an extra time, as it simply overwrites the values from the previous run. But it's a bad idea here, for two reasons: 1. The pager setup may be called very early in the program, before we have found the git repository. As a result, we may fail to read the correct repo-level config file. This is a problem for core.pager, too, but we should at least try to minimize the pollution to other configured values. 2. Because we call setup_pager() from git.c, basically every builtin command _may_ end up reading this config and getting an implicit git_default_config() setup. Which doesn't sound like a terrible thing, except that we don't do it consistently; it triggers only when stdout is a tty. So if a command forgets to load the default config itself (but depends on it anyway), it may appear to work, and then mysteriously fail when the pager is not in use. We can improve this by loading _just_ the core.pager config from git_pager(). Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This means that we may miss out on reading repo-specific config. It's arguable whether this is correct or not. If we were designing from scratch, making "git diff --no-index" completely ignore the repository makes some sense. But we are nowhere near scratch, so let's look at the existing behavior: 1. If you're in the top-level of a repository and run an explicit "diff --no-index", the config subsystem falls back to reading ".git/config", and we will respect repo config. 2. If you're in a subdirectory of a repository, then we still try to read ".git/config", but it generally doesn't exist. So "diff --no-index" there does not respect repo config. 3. If you have $GIT_DIR set in the environment, we read and respect $GIT_DIR/config, 4. If you run "git diff /tmp/foo /tmp/bar" to get an implicit no-index, we _do_ run the repository setup, and set $GIT_DIR (or respect an existing $GIT_DIR variable). We find the repo config no matter where we started, and respect it. So we already respect the repository config in a number of common cases, and case (2) is the only one that does not. And at least one of our tests, t4034, depends on case (1) behaving as it does now (though it is just incidental, not an explicit test for this behavior). So let's bring case (2) in line with the others by always running the repository setup, even with an explicit "--no-index". We shouldn't need to change anything else, as the implicit case already handles the prefix. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

A patch generated by this command will have the filenames "a/../foo" and "b/../bar", no matter which directory we are in with respect to any repository. However, in the implicit case, where we notice that the files are outside the repository, we will have chdir()'d to the top-level of the repository. We then feed the prefix back to the diff machinery. As a result, running the same diff from a subdirectory will result in paths that look like "a/subdir/../../foo". Besides being unnecessarily long, this may also be confusing to the user: they don't care about the subdir or the repository at all; it's just where they happened to be when running the command. We should treat this the same as the explicit --no-index case. One way to address this would be to chdir() back to the original path before running our diff. However, that's a bit hacky, as we would also need to adjust $GIT_DIR, which could be a relative path from our top-level. Instead, we can reuse the diff machinery's RELATIVE_NAME option, which automatically strips off the prefix. Note that this _also_ restricts the diff to this relative prefix, but that's OK for our purposes: we queue our own diff pairs manually, and do not rely on that part of the diff code.
