"git upload-pack" that serves "git fetch" can be told to serve commits that are not at the tip of any ref, as long as they are reachable from a ref, with uploadpack.allowReachableSHA1InWant configuration variable. * fm/fetch-raw-sha1: upload-pack: optionally allow fetching reachable sha1 upload-pack: prepare to extend allow-tip-sha1-in-want config.txt: clarify allowTipSHA1InWant with camelCase

each_ref_fn: change to take an object_id parameter

2015-05-25T19:19:27Z

Change typedef each_ref_fn to take a "const struct object_id *oid" parameter instead of "const unsigned char *sha1". To aid this transition, implement an adapter that can be used to wrap old-style functions matching the old typedef, which is now called "each_ref_sha1_fn"), and make such functions callable via the new interface. This requires the old function and its cb_data to be wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be used as the cb_data for an adapter function, each_ref_fn_adapter(). This is an enormous diff, but most of it consists of simple, mechanical changes to the sites that call any of the "for_each_ref" family of functions. Subsequent to this change, the call sites can be rewritten one by one to use the new interface. Signed-off-by: Michael Haggerty Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

upload-pack: optionally allow fetching reachable sha1

2015-05-23T01:25:36Z

With uploadpack.allowReachableSHA1InWant configuration option set on the server side, "git fetch" can make a request with a "want" line that names an object that has not been advertised (likely to have been obtained out of band or from a submodule pointer). Only objects reachable from the branch tips, i.e. the union of advertised branches and branches hidden by transfer.hideRefs, will be processed. Note that there is an associated cost of having to walk back the history to check the reachability. This feature can be used when obtaining the content of a certain commit, for which the sha1 is known, without the need of cloning the whole repository, especially if a shallow fetch is used. Useful cases are e.g. repositories containing large files in the history, fetching only the needed data for a submodule checkout, when sharing a sha1 without telling which exact branch it belongs to and in Gerrit, if you think in terms of commits instead of change numbers. (The Gerrit case has already been solved through allowTipSHA1InWant as every Gerrit change has a ref.) Signed-off-by: Fredrik Medley Signed-off-by: Junio C Hamano

2015-05-23T01:25:35Z

To allow future extensions, e.g. allowing non-tip sha1, replace the boolean allow_tip_sha1_in_want variable with the flag-style allow_request_with_bare_object_name variable. Signed-off-by: Fredrik Medley Signed-off-by: Junio C Hamano

Identify parts of the code that knows that we use SHA-1 hash to name our objects too much, and use (1) symbolic constants instead of hardcoded 20 as byte count and/or (2) use struct object_id instead of unsigned char [20] for object names. * bc/object-id: apply: convert threeway_stage to object_id patch-id: convert to use struct object_id commit: convert parts to struct object_id diff: convert struct combine_diff_path to object_id bulk-checkin.c: convert to use struct object_id zip: use GIT_SHA1_HEXSZ for trailers archive.c: convert to use struct object_id bisect.c: convert leaf functions to use struct object_id define utility functions for object IDs define a structure for object IDs
