2014-10-30get_merge_bases(): always clean-up object flagsLibravatar Junio C Hamano1-2/+2
The callers of get_merge_bases() can choose to leave object flags used during the merge-base traversal by passing cleanup=0 as a parameter, but in practice a very few callers can afford to do so (namely, "git merge-base"), as they need to compute merge base in preparation for other processing of their own and they need to see the object without contaminate flags. Change the function signature of get_merge_bases_many() and get_merge_bases() to drop the cleanup parameter, so that the majority of the callers do not have to say ", 1" at the end. Give a new get_merge_bases_many_dirty() API to support only a few callers that know they do not need to spend cycles cleaning up the object flags. Signed-off-by: Junio C Hamano <gitster@pobox.com>

Two identical loops in suggest_conflicts() in merge, and do_recursive_merge() in sequencer, can use a single helper function extracted from the latter that prepares the "Conflicts:" hint that is meant to remind the user the paths for which merge conflicts had to be resolved to write a better commit log message.

2014-10-15refs.c: change resolve_ref_unsafe reading argument to be a flags fieldLibravatar Ronnie Sahlberg1-1/+1
resolve_ref_unsafe takes a boolean argument for reading (a nonexistent ref resolves successfully for writing but not for reading). Change this to be a flags field instead, and pass the new constant RESOLVE_REF_READING when we want this behaviour. While at it, swap two of the arguments in the function to put output arguments at the end. As a nice side effect, this ensures that we can catch callers that were unaware of the new API so they can be audited. Give the wrapper functions resolve_refdup and read_ref_full the same treatment for consistency.

2014-06-12commit_tree: take a pointer/len pair rather than a const strbufLibravatar Jeff King1-4/+4
While strbufs are pretty common throughout our code, it is more flexible for functions to take a pointer/len pair than a strbuf. It's easy to turn a strbuf into such a pair (by dereferencing its members), but less easy to go the other way (you can strbuf_attach, but that has implications about memory ownership). This patch teaches commit_tree (and its associated callers and sub-functions) to take such a pair for the commit message rather than a strbuf. This makes passing the buffer around slightly more verbose, but means we can get rid of some dangerous strbuf_attach calls in the next patch.

2013-07-09Convert "struct cache_entry *" to "const ..." wherever possibleLibravatar Nguyễn Thái Ngọc Duy1-1/+1
I attempted to make index_state->cache[] a "const struct cache_entry **" to find out how existing entries in index are modified and where. The question I have is what do we do if we really need to keep track of on-disk changes in the index. The result is - diff-lib.c: setting CE_UPTODATE - name-hash.c: setting CE_HASHED - preload-index.c, read-cache.c, unpack-trees.c and builtin/update-index: obvious - entry.c: write_entry() may refresh the checked out entry via fill_stat_cache_info(). This causes "non-const struct cache_entry *" in builtin/apply.c, builtin/checkout-index.c and builtin/checkout.c - builtin/ls-files.c: --with-tree changes stagemask and may set CE_UPDATE Of these, write_entry() and its call sites are probably most interesting because it modifies on-disk info. But this is stat info and can be retrieved via refresh, at least for porcelain commands. Other just uses ce_flags for local purposes. So, keeping track of "dirty" entries is just a matter of setting a flag in index modification functions exposed by read-cache.c. Except unpack-trees, the rest of the code base does not do anything funny behind read-cache's back. The actual patch is less valueable than the summary above. But if anyone wants to re-identify the above sites. Applying this patch, then this: diff --git a/cache.h b/cache.h index 430d021..1692891 100644 --- a/cache.h +++ b/cache.h @@ -267,7 +267,7 @@ static inline unsigned int canon_mode(unsigned int mode) #define cache_entry_size(len) (offsetof(struct cache_entry,name) + (len) + 1) struct index_state { - struct cache_entry **cache; + const struct cache_entry **cache; unsigned int version; unsigned int cache_nr, cache_alloc, cache_changed; struct string_list *resolve_undo; will help quickly identify them without bogus warnings.

2013-07-02merge: handle --ff/--no-ff/--ff-only as a tri-state optionLibravatar Miklos Vajna1-22/+33
These three options mean "favor fast-forwarding when possible, without creating an unnecessary merge", "never fast-forward and always create a merge commit even when the commit being merged is a strict descendant", and "we do not want to create any merge commit; update only when the merged commit is a strict descendant". They are "pick one out of these three possibilities" options, and correspond to "merge.ff" configuration that is tri-state (yes, no and only). However, the implementation did not follow the usual convention for the command line options (later one wins, and command line overrides what is in the configuration). Fix this by consolidating two variables (fast_forward_only and allow_fast_forward) used in the implementation into one enum that can take one of the three possible values.
