2015-05-28submodule doc: reorder introductory paragraphsLibravatar Stefan Beller1-28/+22
It's better to start the man page with a description of what submodules actually are, instead of saying what they are not. Reorder the paragraphs such that - the first short paragraph introduces the submodule concept, - the second paragraph highlights the usage of the submodule command, - the third paragraph giving background information, and finally - the fourth paragraph discusing alternatives such as subtrees and remotes, which we don't want to be confused with. This ordering deepens the knowledge on submodules with each paragraph. First the basic questions like "How/what" will be answered, while the underlying concepts will be taught at a later time. Making sure it is not confused with subtrees and remotes is not really enhancing knowledge of submodules itself, but rather painting the big picture of git concepts, so you could also argue to have it as the second paragraph. Personally I think this may confuse readers, specially newcomers though. Additionally to reordering the paragraphs, they have been slightly reworded.

2015-05-26diff.c: --ws-error-highlight=<kind> optionLibravatar Junio C Hamano1-0/+10
Traditionally, we only cared about whitespace breakages introduced in new lines. Some people want to paint whitespace breakages on old lines, too. When they see a whitespace breakage on a new line, they can spot the same kind of whitespace breakage on the corresponding old line and want to say "Ah, those breakages are there but they were inherited from the original, so let's not touch them for now." Introduce `--ws-error-highlight=<kind>` option, that lets them pass a comma separated list of `old`, `new`, and `context` to specify what lines to highlight whitespace errors on.

2015-05-25http-backend: spool ref negotiation requests to bufferLibravatar Jeff King1-0/+9
When http-backend spawns "upload-pack" to do ref negotiation, it streams the http request body to upload-pack, who then streams the http response back to the client as it reads. In theory, git can go full-duplex; the client can consume our response while it is still sending the request. In practice, however, HTTP is a half-duplex protocol. Even if our client is ready to read and write simultaneously, we may have other HTTP infrastructure in the way, including the webserver that spawns our CGI, or any intermediate proxies. In at least one documented case[1], this leads to deadlock when trying a fetch over http. What happens is basically: 1. Apache proxies the request to the CGI, http-backend. 2. http-backend gzip-inflates the data and sends the result to upload-pack. 3. upload-pack acts on the data and generates output over the pipe back to Apache. Apache isn't reading because it's busy writing (step 1). This works fine most of the time, because the upload-pack output ends up in a system pipe buffer, and Apache reads it as soon as it finishes writing. But if both the request and the response exceed the system pipe buffer size, then we deadlock (Apache blocks writing to http-backend, http-backend blocks writing to upload-pack, and upload-pack blocks writing to Apache). We need to break the deadlock by spooling either the input or the output. In this case, it's ideal to spool the input, because Apache does not start reading either stdout _or_ stderr until we have consumed all of the input. So until we do so, we cannot even get an error message out to the client. The solution is fairly straight-forward: we read the request body into an in-memory buffer in http-backend, freeing up Apache, and then feed the data ourselves to upload-pack. But there are a few important things to note: 1. We limit the in-memory buffer to prevent an obvious denial-of-service attack. This is a new hard limit on requests, but it's unlikely to come into play. The default value is 10MB, which covers even the ridiculous 100,000-ref negotation in the included test (that actually caps out just over 5MB). But it's configurable on the off chance that you don't mind spending some extra memory to make even ridiculous requests work. 2. We must take care only to buffer when we have to. For pushes, the incoming packfile may be of arbitrary size, and we should connect the input directly to receive-pack. There's no deadlock problem here, though, because we do not produce any output until the whole packfile has been read. For upload-pack's initial ref advertisement, we similarly do not need to buffer. Even though we may generate a lot of output, there is no request body at all (i.e., it is a GET, not a POST).

2015-05-25each_ref_fn: change to take an object_id parameterLibravatar Michael Haggerty1-1/+1
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.

2015-05-22upload-pack: optionally allow fetching reachable sha1Libravatar Fredrik Medley3-1/+15
With uploadpack.allowReachableSHA1InWant configuration option set on the server side, "git fetch" can make a request with a "want" line that names an object that has not been advertised (likely to have been obtained out of band or from a submodule pointer). Only objects reachable from the branch tips, i.e. the union of advertised branches and branches hidden by transfer.hideRefs, will be processed. Note that there is an associated cost of having to walk back the history to check the reachability. This feature can be used when obtaining the content of a certain commit, for which the sha1 is known, without the need of cloning the whole repository, especially if a shallow fetch is used. Useful cases are e.g. repositories containing large files in the history, fetching only the needed data for a submodule checkout, when sharing a sha1 without telling which exact branch it belongs to and in Gerrit, if you think in terms of commits instead of change numbers. (The Gerrit case has already been solved through allowTipSHA1InWant as every Gerrit change has a ref.)
