standardize usage info string format

2015-01-14T17:32:04Z

This patch puts the usage info strings that were not already in docopt- like format into docopt-like format, which will be a litle easier for end users and a lot easier for translators. Changes include: - Placing angle brackets around fill-in-the-blank parameters - Putting dashes in multiword parameter names - Adding spaces to [-f|--foobar] to make [-f | --foobar] - Replacing * with [...] Signed-off-by: Alex Henrie Reviewed-by: Matthieu Moy Signed-off-by: Junio C Hamano

Merge branch 'nd/shallow-clone'

2014-01-17T20:21:20Z

Fetching from a shallow-cloned repository used to be forbidden, primarily because the codepaths involved were not carefully vetted and we did not bother supporting such usage. This attempts to allow object transfer out of a shallow-cloned repository in a controlled way (i.e. the receiver become a shallow repository with truncated history). * nd/shallow-clone: (31 commits) t5537: fix incorrect expectation in test case 10 shallow: remove unused code send-pack.c: mark a file-local function static git-clone.txt: remove shallow clone limitations prune: clean .git/shallow after pruning objects clone: use git protocol for cloning shallow repo locally send-pack: support pushing from a shallow clone via http receive-pack: support pushing to a shallow clone via http smart-http: support shallow fetch/clone remote-curl: pass ref SHA-1 to fetch-pack as well send-pack: support pushing to a shallow clone receive-pack: allow pushes that update .git/shallow connected.c: add new variant that runs with --shallow-file add GIT_SHALLOW_FILE to propagate --shallow-file to subprocesses receive/send-pack: support pushing from a shallow clone receive-pack: reorder some code in unpack() fetch: add --update-shallow to accept refs that update .git/shallow upload-pack: make sure deepening preserves shallow roots fetch: support fetching from a shallow repository clone: support remote shallow repository ...

clone: support remote shallow repository

2013-12-11T00:14:17Z

Cloning from a shallow repository does not follow the "8 steps for new .git/shallow" because if it does we need to get through step 6 for all refs. That means commit walking down to the bottom. Instead the rule to create .git/shallow is simpler and, more importantly, cheap: if a shallow commit is found in the pack, it's probably used (i.e. reachable from some refs), so we add it. Others are dropped. One may notice this method seems flawed by the word "probably". A shallow commit may not be reachable from any refs at all if it's attached to an object island (a group of objects that are not reachable by any refs). If that object island is not complete, a new fetch request may send more objects to connect it to some ref. At that time, because we incorrectly installed the shallow commit in this island, the user will not see anything after that commit (fsck is still ok). This is not desired. Given that object islands are rare (C Git never sends such islands for security reasons) and do not really harm the repository integrity, a tradeoff is made to surprise the user occasionally but work faster everyday. A new option --strict could be added later that follows exactly the 8 steps. "git prune" can also learn to remove dangling objects _and_ the shallow commits that are attached to them from .git/shallow. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

connect.c: teach get_remote_heads to parse "shallow" lines

No callers pass a non-empty pointer as shallow_points at this stage. As a result, all clients still refuse to talk to shallow repository on the other end. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

git fetch-pack: add --diag-url

2013-12-09T22:54:47Z

The main purpose is to trace the URL parser called by git_connect() in connect.c The main features of the parser can be listed as this: - parse out host and path for URLs with a scheme (git:// file:// ssh://) - parse host names embedded by [] correctly - extract the port number, if present - separate URLs like "file" (which are local) from URLs like "host:repo" which should use ssh Add the new parameter "--diag-url" to "git fetch-pack", which prints the value for protocol, host and path to stderr and exits.

Merge branch 'jc/push-cas'

2013-09-09T21:30:29Z

Allow a safer "rewind of the remote tip" push than blind "--force", by requiring that the overwritten remote ref to be unchanged since the new history to replace it was prepared. The machinery is more or less ready. The "--force" option is again the big red button to override any safety, thanks to J6t's sanity (the original round allowed --lockref to defeat --force). The logic to choose the default implemented here is fragile (e.g. "git fetch" after seeing a failure will update the remote-tracking branch and will make the next "push" pass, defeating the safety pretty easily). It is suitable only for the simplest workflows, and it may hurt users more than it helps them. * jc/push-cas: push: teach --force-with-lease to smart-http transport send-pack: fix parsing of --force-with-lease option t5540/5541: smart-http does not support "--force-with-lease" t5533: test "push --force-with-lease" push --force-with-lease: tie it all together push --force-with-lease: implement logic to populate old_sha1_expect[] remote.c: add command line option parser for "--force-with-lease" builtin/push.c: use OPT_BOOL, not OPT_BOOLEAN cache.h: move remote/connect API out of it
