2016-04-06Merge branch 'sb/submodule-parallel-update'Junio C Hamano
A major part of "git submodule update" has been ported to C to take advantage of the recently added framework to run download tasks in parallel. * sb/submodule-parallel-update: clone: allow an explicit argument for parallel submodule clones submodule update: expose parallelism to the user submodule helper: remove double 'fatal: ' prefix git submodule update: have a dedicated helper for cloning run_processes_parallel: rename parameters for the callbacks run_processes_parallel: treat output of children as byte array submodule update: direct error message to stderr fetching submodules: respect `submodule.fetchJobs` config option submodule-config: drop check against NULL submodule-config: keep update strategy around
2016-03-01run_processes_parallel: treat output of children as byte arrayStefan Beller
We do not want the output to be interrupted by a NUL byte, so we cannot use raw fputs. Introduce strbuf_write to avoid having long arguments in run-command.c.

2016-01-15strbuf: give strbuf_getline() to the "most text friendly" variantJunio C Hamano
Now there is no direct caller to strbuf_getline(), we can demote it to file-scope static that is private to strbuf.c and rename it to strbuf_getdelim(). Rename strbuf_getline_crlf(), which is designed to be the most "text friendly" variant, and allow it to take over this simplest name, strbuf_getline(), so we can add more uses of it without having to type _crlf over and over again in the coming steps.

2016-01-15strbuf: introduce strbuf_getline_{lf,nul}()Junio C Hamano
The strbuf_getline() interface allows a byte other than LF or NUL as the line terminator, but this is only because I wrote these codepaths anticipating that there might be a value other than NUL and LF that could be useful when I introduced line_termination long time ago. No useful caller that uses other value has emerged. By now, it is clear that the interface is overly broad without a good reason. Many codepaths have hardcoded preference to read either LF terminated or NUL terminated records from their input, and then call strbuf_getline() with LF or NUL as the third parameter. This step introduces two thin wrappers around strbuf_getline(), namely, strbuf_getline_lf() and strbuf_getline_nul(), and mechanically rewrites these call sites to call either one of them. The changes contained in this patch are: * introduction of these two functions in strbuf.[ch] * mechanical conversion of all callers to strbuf_getline() with either '\n' or '\0' as the third parameter to instead call the respective thin wrapper. After this step, output from "git grep 'strbuf_getline('" would become a lot smaller. An interim goal of this series is to make this an empty set, so that we can have strbuf_getline_crlf() take over the shorter name strbuf_getline(). Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-01-14strbuf: make strbuf_getline_crlf() globalJunio C Hamano
Often we read "text" files that are supplied by the end user (e.g. commit log message that was edited with $GIT_EDITOR upon 'git commit -e'), and in some environments lines in a text file are terminated with CRLF. Existing strbuf_getline() knows to read a single line and then strip the terminating byte from the result, but it is handy to have a version that is more tailored for a "text" input that takes both '\n' and '\r\n' as line terminator (aka <newline> in POSIX lingo) and returns the body of the line after stripping <newline>. Recently reimplemented "git am" uses such a function implemented privately; move it to strbuf.[ch] and make it available for others. Note that we do not blindly replace calls to strbuf_getline() that uses LF as the line terminator with calls to strbuf_getline_crlf() and this is very much deliberate. Some callers may want to treat an incoming line that ends with CR (and terminated with LF) to have a payload that includes the final CR, and such a blind replacement will result in misconversion when done without code audit.

2015-10-26Merge branch 'tk/stripspace'Junio C Hamano
The internal stripspace() function has been moved to where it logically belongs to, i.e. strbuf API, and the command line parser of "git stripspace" has been updated to use the parse_options API. * tk/stripspace: stripspace: use parse-options for command-line parsing strbuf: make stripspace() part of strbuf
2015-10-16strbuf: make stripspace() part of strbufTobias Klauser
This function is also used in other builtins than stripspace, so it makes sense to have it in a more generic place. Since it operates on an strbuf and the function is declared in strbuf.h, move it to strbuf.c and add the corresponding prefix to its name, just like other API functions in the strbuf_* family. Also switch all current users of stripspace() to the new function name and keep a temporary wrapper inline function for any topic branches still using stripspace().

2015-09-25add reentrant variants of sha1_to_hex and find_unique_abbrevJeff King
The sha1_to_hex and find_unique_abbrev functions always write into reusable static buffers. There are a few problems with this: - future calls overwrite our result. This is especially annoying with find_unique_abbrev, which does not have a ring of buffers, so you cannot even printf() a result that has two abbreviated sha1s. - if you want to put the result into another buffer, we often strcpy, which looks suspicious when auditing for overflows. This patch introduces sha1_to_hex_r and find_unique_abbrev_r, which write into a user-provided buffer. Of course this is just punting on the overflow-auditing, as the buffer obviously needs to be GIT_SHA1_HEXSZ + 1 bytes. But it is much easier to audit, since that is a well-known size. We retain the non-reentrant forms, which just become thin wrappers around the reentrant ones. This patch also adds a strbuf variant of find_unique_abbrev, which will be handy in later patches.

2015-04-16strbuf_addch: avoid calling strbuf_growJeff King
We mark strbuf_addch as inline, because we expect it may be called from a tight loop. However, the first thing it does is call the non-inline strbuf_grow(), which can handle arbitrary-sized growth. Since we know that we only need a single character, we can use the inline strbuf_avail() to quickly check whether we need to grow at all. Our check is redundant when we do call strbuf_grow(), but that's OK. The common case is that we avoid calling it at all, and we have made that case faster. On a silly pathological case: perl -le ' print "[core]"; print "key$_ = value$_" for (1..1000000) ' >input git config -f input core.key1 this dropped the time to run git-config from: real 0m0.159s user 0m0.152s sys 0m0.004s to: real 0m0.140s user 0m0.136s sys 0m0.004s for a savings of 12%.

2015-01-16strbuf.h: drop boilerplate descriptions of strbuf_split_*Jeff King
The description of strbuf_split_buf says most of what needs to be said for all of the split variants that take strings, raw memory, etc. We have a boilerplate comment above each that points to the first. This boilerplate ends up making it harder to read, because it spaces out the functions, which could otherwise be read as a group. Let's drop the boilerplate completely, and mention the variants in the top comment. This is perhaps slightly worse for a hypothetical system which pulls the documentation for each function out of the comment immediately preceding it. But such a system does not yet exist, and anyway, the end result of extracting the boilerplate comments would not lead to a very easy-to-read result. We would do better in the long run to teach the extraction system about groups of related functions. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-01-16strbuf.h: reorganize api function grouping headersJeff King
The original API doc had something like: Functions --------- * Life cycle ... some life-cycle functions ... * Related to the contents of the buffer ... functions related to contents .... etc This grouping can be hard to read in the comment sources, given the "*" in the comment lines, and the amount of text between each section. Instead, let's make a flat list of groupings, and underline each as a section header. That makes them stand out, and eliminates the weird half-phrase of "Related to...".

2015-01-16strbuf.h: integrate api-strbuf.txt documentationJeff King
Some of strbuf is documented as comments above functions, and some is separate in Documentation/technical/api-strbuf.txt. This makes it annoying to find the appropriate documentation. We'd rather have it all in one place, which means all in the text document, or all in the header. Let's choose the header as that place. Even though the formatting is not quite as pretty, this keeps the documentation close to the related code. The hope is that this makes it easier to find what you want (human-readable comments are right next to the C declarations), and easier for writers to keep the documentation up to date. This is more or less a straight import of the text from api-strbuf.txt into C comments, complete with asciidoc formatting. The exceptions are: 1. All comments created in this way are started with "/**" to indicate they are part of the API documentation. This may help later with extracting the text to pretty-print it. 2. Function descriptions do not repeat the function name, as it is available in the context directly below. So: `strbuf_add`:: Add data of given length to the buffer. from api-strbuf.txt becomes: /** * Add data of given length to the buffer. */ void strbuf_add(struct strbuf *sb, const void *, size_t); As a result, any block-continuation required in asciidoc for that list item was dropped in favor of straight blank-line paragraph (since it is not necessary when we are not in a list item). 3. There is minor re-wording to integrate existing comments and api-strbuf text. In each case, I took whichever version was more descriptive, and eliminated any redundancies. In one case, for strbuf_addstr, the api documentation gave its inline definition; I eliminated this as redundant with the actual definition, which can be seen directly below the comment. 4. The functions in the header file are re-ordered to match the ordering of the API documentation, under the assumption that more thought went into the grouping there.
