Merge branch 'sb/submodule-parallel-update'

2016-04-06T18:39:01Z

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

run_processes_parallel: treat output of children as byte array

2016-03-01T19:57:19Z

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. Reviewed-by: Jonathan Nieder Signed-off-by: Stefan Beller Signed-off-by: Junio C Hamano

Merge branch 'jc/strbuf-getline'

2016-01-29T00:10:14Z

The preliminary clean-up for jc/peace-with-crlf topic. * jc/strbuf-getline: strbuf: give strbuf_getline() to the "most text friendly" variant checkout-index: there are only two possible line terminations update-index: there are only two possible line terminations check-ignore: there are only two possible line terminations check-attr: there are only two possible line terminations mktree: there are only two possible line terminations strbuf: introduce strbuf_getline_{lf,nul}() strbuf: make strbuf_getline_crlf() global strbuf: miniscule style fix

strbuf: give strbuf_getline() to the "most text friendly" variant

2016-01-15T18:23:57Z

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.

strbuf: introduce strbuf_getline_{lf,nul}()

2016-01-15T18:12:51Z

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

strbuf: make strbuf_getline_crlf() global

2016-01-14T23:05:55Z

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 in POSIX lingo) and returns the body of the line after stripping . 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.

strbuf: add strbuf_read_once to read without blocking

2015-12-16T20:06:08Z

The new call will read from a file descriptor into a strbuf once. The underlying call xread is just run once. xread only reattempts reading in case of EINTR, which makes it suitable to use for a nonblocking read. Signed-off-by: Stefan Beller Signed-off-by: Junio C Hamano

Merge branch 'tk/stripspace'

2015-10-26T22:55:20Z

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
