2021-04-01builtin/clone.c: add --reject-shallow optionLibravatar Li Linchao1-1/+6
In some scenarios, users may want more history than the repository offered for cloning, which happens to be a shallow repository, can give them. But because users don't know it is a shallow repository until they download it to local, we may want to refuse to clone this kind of repository, without creating any unnecessary files. The '--depth=x' option cannot be used as a solution; the source may be deep enough to give us 'x' commits when cloned, but the user may later need to deepen the history to arbitrary depth. Teach '--reject-shallow' option to "git clone" to abort as soon as we find out that we are cloning from a shallow repository.

2020-09-17maintenance: replace run_auto_gc()Libravatar Derrick Stolee1-3/+3
The run_auto_gc() method is used in several places to trigger a check for repo maintenance after some Git commands, such as 'git commit' or 'git fetch'. To allow for extra customization of this maintenance activity, replace the 'git gc --auto [--quiet]' call with one to 'git maintenance run --auto [--quiet]'. As we extend the maintenance builtin with other steps, users will be able to select different maintenance activities. Rename run_auto_gc() to run_auto_maintenance() to be clearer what is happening on this call, and to expose all callers in the current diff. Rewrite the method to use a struct child_process to simplify the calls slightly. Since 'git fetch' already allows disabling the 'git gc --auto' subprocess, add an equivalent option with a different name to be more descriptive of the new behavior: '--[no-]maintenance'. Update the documentation to include these options at the same time. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-11-22clone: add --sparse modeLibravatar Derrick Stolee1-1/+7
When someone wants to clone a large repository, but plans to work using a sparse-checkout file, they either need to do a full checkout first and then reduce the patterns they included, or clone with --no-checkout, set up their patterns, and then run a checkout manually. This requires knowing a lot about the repo shape and how sparse-checkout works. Add a new '--sparse' option to 'git clone' that initializes the sparse-checkout file to include the following patterns: /* !/*/ These patterns include every file in the root directory, but no directories. This allows a repo to include files like a README or a bootstrapping script to grow enlistments from that point. During the 'git sparse-checkout init' call, we must first look to see if HEAD is valid, since 'git clone' does not have a valid HEAD at the point where it initializes the sparse-checkout. The following checkout within the clone command will create the HEAD ref and update the working directory correctly.

2019-05-28clone: add `--remote-submodules` flagLibravatar Ben Avison1-1/+8
When using `git clone --recurse-submodules` there was previously no way to pass a `--remote` switch to the implicit `git submodule update` command for any use case where you want the submodules to be checked out on their remote-tracking branch rather than with the SHA-1 recorded in the superproject. This patch rectifies this situation. It actually passes `--no-fetch` to `git submodule update` as well on the grounds they the submodule has only just been cloned, so fetching from the remote again only serves to slow things down.

2019-04-18clone: send server options when using protocol v2Libravatar Jonathan Tan1-0/+8
Commit 5e3548ef16 ("fetch: send server options when using protocol v2", 2018-04-24) taught "fetch" the ability to send server options when using protocol v2, but not "clone". This ability is triggered by "-o" or "--server-option". Teach "clone" the same ability, except that because "clone" already has "-o" for another parameter, teach "clone" only to receive "--server-option". Explain in the documentation, both for clone and for fetch, that server handling of server options are server-specific. This is similar to receive-pack's handling of push options - currently, they are just sent to hooks to interpret as they see fit.

When formatted as a man page, 1st section header is always in upper case even if we write it otherwise. Make all 1st section headers uppercase to keep it close to the final output.

Some sections perhaps should become second sections instead, where case is kept, and for better organization. I will update if anyone has suggestions about this.

There have been a few complaints on the mailing list that git-clone doesn't respect the `submodule.recurse` setting, which every other command (that potentially knows how to deal with submodules) respects. In case of clone this is not beneficial to respect as the user may not want to obtain all submodules (assuming a pathspec of '.'). Improve the documentation such that the pathspec is mentioned in the synopsis to alleviate the confusion around the submodule recursion flag in git-clone. While at it clarify that the option can be given multiple times for complex pathspecs. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-05-01clone: add a --no-tags option to clone without tagsLibravatar Ævar Arnfjörð Bjarmason1-1/+13
Add a --no-tags option to clone without fetching any tags. Without this change there's no easy way to clone a repository without also fetching its tags. When supplying --single-branch the primary remote branch will be cloned, but in addition tags will be followed & retrieved. Now --no-tags can be added --single-branch to clone a repository without tags, and which only tracks a single upstream branch. This option works without --single-branch as well, and will do a normal clone but not fetch any tags. Many git commands pay some fixed overhead as a function of the number of references. E.g. creating ~40k tags in linux.git will cause a command like `git log -1 >/dev/null` to run in over a second instead of in a matter of milliseconds, in addition numerous other things will slow down, e.g. "git log <TAB>" with the bash completion will slowly show ~40k references instead of 1. The user might want to avoid all of that overhead to simply use a repository like that to browse the "master" branch, or something like a CI tool might want to keep that one branch up-to-date without caring about any other references. Without this change the only way of accomplishing this was either by manually tweaking the config in a fresh repository: git init git && cat >git/.git/config <<EOF && [remote "origin"] url = git@github.com:git/git.git tagOpt = --no-tags fetch = +refs/heads/master:refs/remotes/origin/master [branch "master"] remote = origin merge = refs/heads/master EOF cd git && git pull Which requires hardcoding the "master" name, which may not be the main --single-branch would have retrieved, or alternatively by setting tagOpt=--no-tags right after cloning & deleting any existing tags: git clone --single-branch git@github.com:git/git.git && cd git && git config remote.origin.tagOpt --no-tags && git tag -l | xargs git tag -d Which of course was also subtly buggy if --branch was pointed at a tag, leaving the user in a detached head: git clone --single-branch --branch v2.12.0 git@github.com:git/git.git && cd git && git config remote.origin.tagOpt --no-tags && git tag -l | xargs git tag -d Now all this complexity becomes the much simpler: git clone --single-branch --no-tags git@github.com:git/git.git Or in the case of cloning a single tag "branch": git clone --single-branch --branch v2.12.0 --no-tags git@github.com:git/git.git Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-03-18clone: teach --recurse-submodules to optionally take a pathspecLibravatar Brandon Williams1-5/+9
Teach clone --recurse-submodules to optionally take a pathspec argument which describes which submodules should be recursively initialized and cloned. If no pathspec is provided, --recurse-submodules will recursively initialize and clone all submodules by using a default pathspec of ".". In order to construct more complex pathspecs, --recurse-submodules can be given multiple times. This also configures the 'submodule.active' configuration option to be the given pathspec, such that any future invocation of `git submodule update` will keep up with the pathspec. Additionally the switch '--recurse' is removed from the Documentation as well as marked hidden in the options array, to streamline the options for submodules. A simple '--recurse' doesn't convey what is being recursed, e.g. it could mean directories or trees (c.f. ls-tree) In a lot of other commands we already have '--recurse-submodules' to mean recursing into submodules, so advertise this spelling here as the genuine option.

2016-04-26clone: add `--shallow-submodules` flagLibravatar Stefan Beller1-3/+10
When creating a shallow clone of a repository with submodules, the depth argument does not influence the submodules, i.e. the submodules are done as non-shallow clones. It is unclear what the best default is for the depth of submodules of a shallow clone, so we need to have the possibility to do all kinds of combinations: * shallow super project with shallow submodules e.g. build bots starting always from scratch. They want to transmit the least amount of network data as well as using the least amount of space on their hard drive. * shallow super project with unshallow submodules e.g. The superproject is just there to track a collection of repositories and it is not important to have the relationship between the repositories intact. However the history of the individual submodules matter. * unshallow super project with shallow submodules e.g. The superproject is the actual project and the submodule is a library which is rarely touched. The new switch to select submodules to be shallow or unshallow supports all of these three cases. It is easy to transition from the first to the second case by just unshallowing the submodules (`git submodule foreach git fetch --unshallow`), but it is not possible to transition from the second to the first case (as we would have already transmitted the non shallow over the network). That is why we want to make the first case the default in case of a shallow super project. This leads to the inconvenience in the second case with the shallow super project and unshallow submodules, as you need to pass `--no-shallow-submodules`.

2016-02-01transport: drop support for git-over-rsyncLibravatar Jeff King1-2/+1
The git-over-rsync protocol is inefficient and broken, and has been for a long time. It transfers way more objects than it needs (grabbing all of the remote's "objects/", regardless of which objects we need). It does its own ad-hoc parsing of loose and packed refs from the remote, but doesn't properly override packed refs with loose ones, leading to garbage results (e.g., expecting the other side to have an object pointed to by a stale packed-refs entry, or complaining that the other side has two copies of the refs[1]). This latter breakage means that nobody could have successfully pulled from a moderately active repository since cd547b4 (fetch/push: readd rsync support, 2007-10-01). We never made an official deprecation notice in the release notes for git's rsync protocol, but the tutorial has marked it as such since 914328a (Update tutorial., 2005-08-30). And on the mailing list as far back as Oct 2005, we can find Junio mentioning it as having "been deprecated for quite some time."[2,3,4]. So it was old news then; cogito had deprecated the transport in July of 2005[5] (though it did come back briefly when Linus broke git-http-pull!). Of course some people professed their love of rsync through 2006, but Linus clarified in his usual gentle manner[6]: > Thanks! This is why I still use rsync, even though > everybody and their mother tells me "Linus says rsync is > deprecated." No. You're using rsync because you're actively doing something _wrong_. The deprecation sentiment was reinforced in 2008, with a mention that cloning via rsync is broken (with no fix)[7]. Even the commit porting rsync over to C from shell (cd547b4) lists it as deprecated! So between the 10 years of informal warnings, and the fact that it has been severely broken since 2007, it's probably safe to simply remove it without further deprecation warnings.

The way to allow the borrowed repository to be removed is to repack the borrowing repository (i.e. run "git repack -a -d" in Q); while power users may know it very well, it is not easily discoverable.

Now that git supports data transfer from or to a shallow clone, these limitations are not true anymore. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-07-15Revert "git-clone.txt: remove the restriction on pushing from a shallow clone"Libravatar Junio C Hamano1-7/+5
This reverts commit dacd2bcc414e0b7aac36aaa400da0a743c4741cc. "It fails reliably without corrupting the receiving repository when it should fail" may be better than the situation before the receiving end was hardened recently, but the fact that sometimes the push does not go through still remains. It is better to advice the users that they cannot push from a shallow repository as a limitation before they decide to use (or not to use) a shallow clone.

2013-07-12git-clone.txt: remove the restriction on pushing from a shallow cloneLibravatar Nguyễn Thái Ngọc Duy1-5/+7
The document says one cannot push from a shallow clone. But that is not true (maybe it was at some point in the past). The client does not stop such a push nor does it give any indication to the receiver that this is a shallow push. If the receiver accepts it, it's in. Since 52fed6e (receive-pack: check connectivity before concluding "git push" - 2011-09-02), receive-pack is prepared to deal with broken push, a shallow push can't cause any corruption. Update the document to reflect that. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-06-22Documentation: Update 'linux-2.6.git' -> 'linux.git'Libravatar W. Trevor King1-2/+2
The 3.x tree has been out for a while now. The -2.6 repository name survived the initial release [1], but kernel.org now only lists 'linux.git' (for aegl as well as torvalds) [2].

2013-06-22doc/clone: Pick more compelling paths for the --reference exampleLibravatar W. Trevor King1-4/+4
There may be times when using one of your local repositories as a reference for a new clone make sense, but the implied version-bump in the old example isn't one of them. I think a more intuitive example is multi-user system with a central reference clone, and the new paths hint at this use case. Signed-off-by: W.
