Merge branch 'mh/replace-refs'

2015-08-03T18:01:10Z

Add an environment variable to tell Git to look into refs hierarchy other than refs/replace/ for the object replacement data. * mh/replace-refs: Allow to control where the replace refs are looked for

convert "enum date_mode" into a struct

2015-06-29T18:39:07Z

In preparation for adding date modes that may carry extra information beyond the mode itself, this patch converts the date_mode enum into a struct. Most of the conversion is fairly straightforward; we pass the struct as a pointer and dereference the type field where necessary. Locations that declare a date_mode can use a "{}" constructor. However, the tricky case is where we use the enum labels as constants, like: show_date(t, tz, DATE_NORMAL); Ideally we could say: show_date(t, tz, &{ DATE_NORMAL }); but of course C does not allow that. Likewise, we cannot cast the constant to a struct, because we need to pass an actual address. Our options are basically: 1. Manually add a "struct date_mode d = { DATE_NORMAL }" definition to each caller, and pass "&d". This makes the callers uglier, because they sometimes do not even have their own scope (e.g., they are inside a switch statement). 2. Provide a pre-made global "date_normal" struct that can be passed by address. We'd also need "date_rfc2822", "date_iso8601", and so forth. But at least the ugliness is defined in one place. 3. Provide a wrapper that generates the correct struct on the fly. The big downside is that we end up pointing to a single global, which makes our wrapper non-reentrant. But show_date is already not reentrant, so it does not matter. This patch implements 3, along with a minor macro to keep the size of the callers sane.

Allow to control where the replace refs are looked for

2015-06-12T22:28:17Z

It can be useful to have grafts or replace refs for specific use-cases while keeping the default "view" of the repository pristine (or with a different set of grafts/replace refs). It is possible to use a different graft file with GIT_GRAFT_FILE, but while replace refs are more powerful, they don't have an equivalent override. Add a GIT_REPLACE_REF_BASE environment variable to control where git is going to look for replace refs. Signed-off-by: Mike Hommey Signed-off-by: Junio C Hamano

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

Merge branch 'mg/log-decorate-HEAD'

2015-05-22T19:41:51Z

The "log --decorate" enhancement in Git 2.4 that shows the commit at the tip of the current branch e.g. "HEAD -> master", did not work with --decorate=full. * mg/log-decorate-HEAD: log: do not shorten decoration names too early log: decorate HEAD with branch name under --decorate=full, too

log: do not shorten decoration names too early

2015-05-13T19:40:57Z

The DECORATE_SHORT_REFS option given to load_ref_decorations() affects the way a copy of the refname is stored for each decorated commit, and this forces later steps like current_pointed_by_HEAD() to adjust their behaviour based on this initial settings. Instead, we can always store the full refname and then shorten them when producing the output. Signed-off-by: Junio C Hamano

log: decorate HEAD with branch name under --decorate=full, too

2015-05-13T17:25:18Z

The previous step to teach "log --decorate" to show "HEAD -> master" instead of "HEAD, master" when showing the commit at the tip of the 'master' branch, when the 'master' branch is checked out, did not work for "log --decorate=full". The commands in the "log" family prepare commit decorations for all refs upfront, and the actual string used in a decoration depends on how load_ref_decorations() is called very early in the process. By default, "git log --decorate" stores names with common prefixes such as "refs/heads" stripped; "git log --decorate=full" stores the full refnames. When the current_pointed_by_HEAD() function has to decide if "HEAD" points at the branch a decoration describes, however, what was passed to load_ref_decorations() to decide to strip (or keep) such a common prefix is long lost. This makes it impossible to reliably tell if a decoration that stores "refs/heads/master", for example, is the 'master' branch (under "--decorate" with prefix omitted) or 'refs/heads/master' branch (under "--decorate=full"). Keep what was passed to load_ref_decorations() in a global next to the global variable name_decoration, and use that to decide how to match what was read from "HEAD" and what is in a decoration.
