git/upload-pack.c, branch v2.16.2

Merge branch 'bw/protocol-v1'

2017-12-06T17:23:44Z

A new mechanism to upgrade the wire protocol in place is proposed and demonstrated that it works with the older versions of Git without harming them. * bw/protocol-v1: Documentation: document Extra Parameters ssh: introduce a 'simple' ssh variant i5700: add interop test for protocol transition http: tell server that the client understands v1 connect: tell server that the client understands v1 connect: teach client to recognize v1 server response upload-pack, receive-pack: introduce protocol version 1 daemon: recognize hidden request arguments protocol: introduce protocol extension mechanisms pkt-line: add packet_write function connect: in ref advertisement, shallows are last

upload-pack, receive-pack: introduce protocol version 1

2017-10-17T01:51:29Z

Teach upload-pack and receive-pack to understand and respond using protocol version 1, if requested. Protocol version 1 is simply the original and current protocol (what I'm calling version 0) with the addition of a single packet line, which precedes the ref advertisement, indicating the protocol version being spoken.

refs: convert peel_ref to struct object_id

2017-10-16T02:05:51Z

Convert peel_ref (and its corresponding backend) to struct object_id. This transformation was done with an update to the declaration, definition, comments, and test helper and the following semantic patch: @@ expression E1, E2; @@ - peel_ref(E1, E2.hash) + peel_ref(E1, &E2) @@ expression E1, E2; @@ - peel_ref(E1, E2->hash) + peel_ref(E1, E2) Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

refs: convert dwim_ref and expand_ref to struct object_id

2017-10-16T02:05:51Z

All of the callers of these functions just pass the hash member of a struct object_id, so convert them to use a pointer to struct object_id directly. Insert a check for NULL in expand_ref on a temporary basis; this check can be removed when resolve_ref_unsafe is converted as well. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

Merge branch 'ma/leakplugs'

2017-09-29T02:23:43Z

Memory leaks in various codepaths have been plugged. * ma/leakplugs: pack-bitmap[-write]: use `object_array_clear()`, don't leak object_array: add and use `object_array_pop()` object_array: use `object_array_clear()`, not `free()` leak_pending: use `object_array_clear()`, not `free()` commit: fix memory leak in `reduce_heads()` builtin/commit: fix memory leak in `prepare_index()`

refs: pass NULL to resolve_ref_unsafe() if hash is not needed

2017-09-24T01:18:21Z

This allows us to get rid of some write-only variables, among them seven SHA1 buffers. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

object_array: use `object_array_clear()`, not `free()`

2017-09-24T01:06:01Z

Instead of freeing `foo.objects` for an object array `foo` (sometimes conditionally), call `object_array_clear(&foo)`. This means we don't poke as much into the implementation, which is already a good thing, but also that we release the individual entries as well, thereby fixing at least one memory-leak (in diff-lib.c). If someone is holding on to a pointer to an element's `name` or `path`, that is now a dangling pointer, i.e., we'd be turning an unpleasant situation into an outright bug. To the best of my understanding no such long-term pointers are being taken. The way we handle `study` in builting/reflog.c still looks like it might leak. That will be addressed in the next commit.

Merge branch 'bw/config-h'

2017-06-24T21:28:41Z

Fix configuration codepath to pay proper attention to commondir that is used in multi-worktree situation, and isolate config API into its own header file. * bw/config-h: config: don't implicitly use gitdir or commondir config: respect commondir setup: teach discover_git_directory to respect the commondir config: don't include config.h by default config: remove git_config_iter config: create config.h

config: don't include config.h by default

2017-06-15T19:56:22Z

Stop including config.h by default in cache.h. Instead only include config.h in those files which require use of the config system. Signed-off-by: Brandon Williams Signed-off-by: Junio C Hamano
