Merge branch 'nd/log-show-linear-break'

2014-04-03T19:38:11Z

Attempts to show where a single-strand-of-pearls break in "git log" output. * nd/log-show-linear-break: log: add --show-linear-break to help see non-linear history object.h: centralize object flag allocation

object.h: centralize object flag allocation

2014-03-25T22:09:24Z

While the field "flags" is mainly used by the revision walker, it is also used in many other places. Centralize the whole flag allocation to one place for a better overview (and easier to move flags if we have too). Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

Merge branch 'nd/upload-pack-shallow'

2014-03-21T19:49:08Z

Serving objects from a shallow repository needs to write a temporary file to be used, but the serving upload-pack may not have write access to the repository which is meant to be read-only. Instead feed these temporary shallow bounds from the standard input of pack-objects so that we do not have to use a temporary file. * nd/upload-pack-shallow: upload-pack: send shallow info over stdin to pack-objects

Merge branch 'jk/shallow-update-fix'

2014-03-21T19:33:29Z

Serving objects from a shallow repository needs to write a new file to hold the temporary shallow boundaries but it was not cleaned when we exit due to die() or a signal. * jk/shallow-update-fix: shallow: verify shallow file after taking lock shallow: automatically clean up shallow tempfiles shallow: use stat_validity to check for up-to-date file

upload-pack: send shallow info over stdin to pack-objects

2014-03-11T20:32:10Z

Before cdab485 (upload-pack: delegate rev walking in shallow fetch to pack-objects - 2013-08-16) upload-pack does not write to the source repository. cdab485 starts to write $GIT_DIR/shallow_XXXXXX if it's a shallow fetch, so the source repo must be writable. git:// servers do not need write access to repos and usually don't have it, which means cdab485 breaks shallow clone over git:// Instead of using a temporary file as the media for shallow points, we can send them over stdin to pack-objects as well. Prepend shallow SHA-1 with --shallow so pack-objects knows what is what. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

shallow: automatically clean up shallow tempfiles

2014-02-27T20:07:13Z

We sometimes write tempfiles of the form "shallow_XXXXXX" during fetch/push operations with shallow repositories. Under normal circumstances, we clean up the result when we are done. However, we do no take steps to clean up after ourselves when we exit due to die() or signal death. This patch teaches the tempfile creation code to register handlers to clean up after ourselves. To handle this, we change the ownership semantics of the filename returned by setup_temporary_shallow. It now keeps a copy of the filename itself, and returns only a const pointer to it. We can also do away with explicit tempfile removal in the callers. They all exit not long after finishing with the file, so they can rely on the auto-cleanup, simplifying the code. Note that we keep things simple and maintain only a single filename to be cleaned. This is sufficient for the current caller, but we future-proof it with a die("BUG").

rename read_replace_refs to check_replace_refs

2014-02-20T22:16:55Z

The semantics of this flag was changed in commit e1111cef23 inline lookup_replace_object() calls but wasn't renamed at the time to minimize code churn. Rename it now, and add a comment explaining its use. Signed-off-by: Michael Haggerty 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 ...

Merge branch 'cc/starts-n-ends-with'

2013-12-17T20:02:44Z

Remove a few duplicate implementations of prefix/suffix comparison functions, and rename them to starts_with and ends_with. * cc/starts-n-ends-with: replace {pre,suf}fixcmp() with {starts,ends}_with() strbuf: introduce starts_with() and ends_with() builtin/remote: remove postfixcmp() and use suffixcmp() instead environment: normalize use of prefixcmp() by removing " != 0"
