This patch teaches the command to interpret the refspecs and show how each branch will be pushed to the destination. The output gives the user an idea of what "git push" should do if it is run w/o any arguments. Example new output: 1a. Typical output with no push refspec (i.e. matching branches only) $ git remote show origin * remote origin [...] Local refs configured for 'git push': master pushes to master (up to date) next pushes to next (local out of date) 1b. Same as above, w/o querying the remote: $ git remote show origin -n * remote origin [...] Local ref configured for 'git push' (status not queried): (matching) pushes to (matching) 2a. With a forcing refspec (+), and a new topic (something like push = refs/heads/*:refs/heads/*): $ git remote show origin * remote origin [...] Local refs configured for 'git push': master pushes to master (fast forwardable) new-topic pushes to new-topic (create) next pushes to next (local out of date) pu forces to pu (up to date) 2b. Same as above, w/o querying the remote $ git remote show origin -n * remote origin [...] Local refs configured for 'git push' (status not queried): master pushes to master new-topic pushes to new-topic next pushes to next pu forces to pu 3. With a remote configured as a mirror: * remote backup [...] Local refs will be mirrored by 'git push' Signed-off-by: Jay Soffian --- builtin-remote.c | 201 ++++++++++++++++++++++++++++++++++++++++++++++++---- t/t5505-remote.sh | 30 ++++++-- 2 files changed, 207 insertions(+), 24 deletions(-) diff --git a/builtin-remote.c b/builtin-remote.c index 379826e..7e82a52 100644 --- a/builtin-remote.c +++ b/builtin-remote.c @@ -21,6 +21,7 @@ static const char * const builtin_remote_usage[] = { #define GET_REF_STATES (1<<0) #define GET_HEAD_NAMES (1<<1) +#define GET_PUSH_REF_STATES (1<<2) static int verbose; @@ -220,7 +221,7 @@ static void read_branches(void) struct ref_states { struct remote *remote; - struct string_list new, stale, tracked, heads; + struct string_list new, stale, tracked, heads, push; int queried; }; @@ -275,6 +276,112 @@ static int get_ref_states(const struct ref *remote_refs, struct ref_states *stat return 0; } +struct push_info { + char *dest; + int forced; + enum { + PUSH_STATUS_CREATE = 0, + PUSH_STATUS_DELETE, + PUSH_STATUS_UPTODATE, + PUSH_STATUS_FASTFORWARD, + PUSH_STATUS_OUTOFDATE, + PUSH_STATUS_NOTQUERIED, + } status; +}; + +static int get_push_ref_states(const struct ref *remote_refs, + struct ref_states *states) +{ + struct remote *remote = states->remote; + struct ref *ref, *local_refs, *push_map, **push_tail; + if (remote->mirror) + return 0; + + local_refs = get_local_heads(); + ref = push_map = copy_ref_list(remote_refs); + while (ref->next) + ref = ref->next; + push_tail = &ref->next; + + match_refs(local_refs, push_map, &push_tail, remote->push_refspec_nr, + remote->push_refspec, MATCH_REFS_NONE); + + states->push.strdup_strings = 1; + for (ref = push_map; ref; ref = ref->next) { + struct string_list_item *item; + struct push_info *info; + + if (!ref->peer_ref) + continue; + hashcpy(ref->new_sha1, ref->peer_ref->new_sha1); + + item = string_list_append(abbrev_branch(ref->peer_ref->name), + &states->push); + item->util = xcalloc(sizeof(struct push_info), 1); + info = item->util; + info->forced = ref->force; + info->dest = xstrdup(abbrev_branch(ref->name)); + + if (is_null_sha1(ref->new_sha1)) { + info->status = PUSH_STATUS_DELETE; + } else if (!hashcmp(ref->old_sha1, ref->new_sha1)) + info->status = PUSH_STATUS_UPTODATE; + else if (is_null_sha1(ref->old_sha1)) + info->status = PUSH_STATUS_CREATE; + else if (has_sha1_file(ref->old_sha1) && + ref_newer(ref->new_sha1, ref->old_sha1)) + info->status = PUSH_STATUS_FASTFORWARD; + else + info->status = PUSH_STATUS_OUTOFDATE; + // ref->peer_ref = NULL; /* local ref which is freed below */ + } + free_refs(local_refs); + free_refs(push_map); + return 0; +} + +static int get_push_ref_states_noquery(struct ref_states *states) +{ + int i; + struct remote *remote = states->remote; + struct string_list_item *item; + struct push_info *info; + + if (remote->mirror) + return 0; + + states->push.strdup_strings = 1; + if (!remote->push_refspec_nr) { + item = string_list_append("(matching)", &states->push); + info = item->util = xcalloc(sizeof(struct push_info), 1); + info->status = PUSH_STATUS_NOTQUERIED; + info->dest = xstrdup(item->string); + } + for (i = 0; i < remote->push_refspec_nr; i++) { + struct refspec *spec = remote->push + i; + char buf[PATH_MAX]; + if (spec->matching) + item = string_list_append("(matching)", &states->push); + else if (spec->pattern) { + snprintf(buf, (sizeof(buf)), "%s*", spec->src); + item = string_list_append(buf, &states->push); + snprintf(buf, (sizeof(buf)), "%s*", spec->dst); + } else if (strlen(spec->src)) + item = string_list_append(spec->src, &states->push); + else + item = string_list_append("(delete)", &states->push); + + info = item->util = xcalloc(sizeof(struct push_info), 1); + info->forced = spec->force; + info->status = PUSH_STATUS_NOTQUERIED; + if (spec->pattern) + info->dest = xstrdup(buf); + else + info->dest = xstrdup(spec->dst ?
