2014-09-15send-pack: factor out capability string generationJunio C Hamano
A run of 'var ? " var" : ""' fed to a long printf string in a deeply nested block was hard to read. Move it outside the loop and format it into a strbuf. As an added bonus, the trick to add "agent=<agent-name>" by using two conditionals is replaced by a more readable version. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-09-15send-pack: always send capabilitiesJunio C Hamano
We tried to avoid sending one extra byte, NUL and nothing behind it to signal there is no protocol capabilities being sent, on the first command packet on the wire, but it just made the code look ugly. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-09-15send-pack: refactor decision to send update per refJunio C Hamano
A new helper function ref_update_to_be_sent() decides for each ref if the update is to be sent based on the status previously set by set_ref_status_for_push() and also if this is a mirrored push. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-09-15send-pack: move REF_STATUS_REJECT_NODELETE logic a bit higherJunio C Hamano
20e8b465 (refactor ref status logic for pushing, 2010-01-08) restructured the code to set status for each ref to be pushed, but did not quite go far enough. We inspect the status set earlier by set_refs_status_for_push() and then perform yet another update to the status of a ref with an otherwise OK status to be deleted to mark it with REF_STATUS_REJECT_NODELETE when the protocol tells us never to delete. Split the latter into a separate loop that comes before we enter the per-ref loop. This way we would have one less condition to check in the main loop.

2014-09-15receive-pack: do not reuse old_sha1[] for other thingsJunio C Hamano

2014-09-15receive-pack: parse feature request a bit earlierJunio C Hamano
Ideally, we should have also allowed the first "shallow" to carry the feature request trailer, but that is water under the bridge now. This makes the next step to factor out the queuing of commands easier to review. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-09-15receive-pack: do not overallocate command structureJunio C Hamano
An "update" command in the protocol exchange consists of 40-hex old object name, SP, 40-hex new object name, SP, and a refname, but the first instance is further followed by a NUL with feature requests. The command structure, which has a flex-array member that stores the refname at the end, was allocated based on the whole length of the update command, without excluding the trailing feature requests.

2014-07-28diff-tree: avoid lookup_unknown_objectJeff King
We generally want to avoid lookup_unknown_object, because it results in allocating more memory for the object than may be strictly necessary. In this case, it is used to check whether we have an already-parsed object before calling parse_object, to save us from reading the object from disk. Using lookup_object would be fine for that purpose, but we can take it a step further. Since this code was written, parse_object already learned the "check lookup_object" optimization, so we can simply call parse_object directly.

2014-07-28object_as_type: set commit indexJeff King
The point of the "index" field of struct commit is that every allocated commit would have one. It is supposed to be an invariant that whenever object->type is set to OBJ_COMMIT, we have a unique index. Commit 969eba6 (commit: push commit_index update into alloc_commit_node, 2014-06-10) covered this case for newly-allocated commits. However, we may also allocate an "unknown" object via lookup_unknown_object, and only later convert it to a commit. We must make sure that we set the commit index when we switch the type field.

2014-07-28alloc: factor out commit indexJeff King
We keep a static counter to set the commit index on newly allocated objects. However, since we also need to set the index on any_objects which are converted to commits, let's make the counter available as a public function. While we're moving it, let's make sure the counter is allocated as an unsigned integer to match the index field in "struct commit".

2014-07-28add object_as_type helper for casting objectsJeff King
When we call lookup_commit, lookup_tree, etc, the logic goes something like: 1. Look for an existing object struct. If we don't have one, allocate and return a new one. 2. Double check that any object we have is the expected type (and complain and return NULL otherwise). 3. Convert an object with type OBJ_NONE (from a prior call to lookup_unknown_object) to the expected type. We can encapsulate steps 2 and 3 in a helper function which checks whether we have the expected object type, converts OBJ_NONE as appropriate, and returns the object. Not only does this shorten the code, but it also provides one central location for converting OBJ_NONE objects into objects of other types. Future patches will use that to enforce type-specific invariants. Since this is a refactoring, we would want it to behave exactly as the current code. It takes a little reasoning to see that this is the case: - for lookup_{commit,tree,etc} functions, we are just pulling steps 2 and 3 into a function that does the same thing. - for the call in peel_object, we currently only do step 3 (but we want to consolidate it with the others, as mentioned above). However, step 2 is a noop here, as the surrounding conditional makes sure we have OBJ_NONE (which we want to keep to avoid an extraneous call to sha1_object_info). - for the call in lookup_commit_reference_gently, we are currently doing step 2 but not step 3. However, step 3 is a noop here. The object we got will have just come from deref_tag, which must have figured out the type for each object in order to know when to stop peeling. Therefore the type will never be OBJ_NONE. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-07-28parse_object_buffer: do not set object typeJeff King
The only way that "obj" can be non-NULL is if it came from one of the lookup_* functions. These functions always ensure that the object has the expected type (and return NULL otherwise), so there is no need for us to set the type.

2014-07-28move setting of object->type to alloc_* functionsJeff King
The "struct object" type implements basic object polymorphism. Individual instances are allocated as concrete types (or as a union type that can store any object), and a "struct object *" can be cast into its real type after examining its "type" enum. This means it is dangerous to have a type field that does not match the allocation (e.g., setting the type field of a "struct blob" to "OBJ_COMMIT" would mean that a reader might read past the allocated memory). In most of the current code this is not a problem; the first thing we do after allocating an object is usually to set its type field by passing it to create_object. However, the virtual commits we create in merge-recursive.c do not ever get their type set. This does not seem to have caused problems in practice, though (presumably because we always pass around a "struct commit" pointer and never even look at the type). We can fix this oversight and also make it harder for future code to get it wrong by setting the type directly in the object allocation functions. This will also make it easier to fix problems with commit index allocation, as we know that any object allocated by alloc_commit_node will meet the invariant that an object with an OBJ_COMMIT type field will have a unique index number.

2014-07-28alloc: write out allocator definitionsJeff King
Because the allocator functions for tree, blobs, etc are all very similar, we originally used a macro to avoid repeating ourselves. Since the prior commit, though, the heavy lifting is done by an inline helper function. The macro does still save us a few lines, but at some readability cost. It obfuscates the function definitions (and makes them hard to find via grep). Much worse, though, is the fact that it isn't used consistently for all allocators. Somebody coming later may be tempted to modify DEFINE_ALLOCATOR, but they would miss alloc_commit_node, which is treated specially. Let's just drop the macro and write everything out explicitly.

2014-07-28alloc.c: remove the alloc_raw_commit_node() functionRamsay Jones
In order to encapsulate the setting of the unique commit index, commit 969eba63 ("commit: push commit_index update into alloc_commit_node", 10-06-2014) introduced a (logically private) intermediary allocator function. However, this function (alloc_raw_commit_node()) was declared as a public function, which undermines its entire purpose. Introduce an inline function, alloc_node(), which implements the main logic of the allocator used by DEFINE_ALLOCATOR, and redefine the macro in terms of the new function. In addition, use the new function in the implementation of the alloc_commit_node() allocator, rather than the intermediary allocator, which can now be removed. Noticed by sparse ("symbol 'alloc_raw_commit_node' was not declared. Should it be static?").

2014-07-24apply: avoid possible bogus pointerJeff King
When parsing "index" lines from a git-diff, we look for a space followed by the mode. If we don't have a space, then we set our pointer to the end-of-line. However, we don't double-check that our end-of-line pointer is valid (e.g., if we got a truncated diff input), which could lead to some wrap-around pointer arithmetic. In most cases this would probably get caught by our "40 < len" check later in the function, but to be on the safe side, let's just use strchrnul to treat end-of-string the same as end-of-line.

2014-07-24fix memory leak parsing core.commentcharJeff King
When we see the core.commentchar config option, we extract the string with git_config_string, which does two things: 1. It complains via config_error_nonbool if there is no string value. 2. It makes a copy of the string. Since we immediately parse the string into its single-character value, we only care about (1). And in fact (2) is a detriment, as it means we leak the copy. Instead, let's just check the pointer value ourselves, and parse directly from the const string we already have.

2014-07-24free ref string returned by dwim_refJeff King
A call to "dwim_ref(name, len, flags, &ref)" will allocate a new string in "ref" to return the exact ref we found. We do not consistently free it in all code paths, leading to small leaks. The worst is in get_sha1_basic, which may be called many times (e.g., by "cat-file --batch"), though it is relatively unlikely, as it only triggers on a bogus reflog specification.
