2010-02-05run-command: support custom fd-set in asyncLibravatar Erik Faye-Lund1-10/+40
This patch adds the possibility to supply a set of non-0 file descriptors for async process communication instead of the default-created pipe. Additionally, we now support bi-directional communiction with the async procedure, by giving the async function both read and write file descriptors. To retain compatiblity and similar "API feel" with start_command, we require start_async callers to set .out = -1 to get a readable file descriptor. If either of .in or .out is 0, we supply no file descriptor to the async process. [sp: Note: Erik started this patch, and a huge bulk of it is his work. All bugs were introduced later by Shawn.] Signed-off-by: Erik Faye-Lund <kusmabite@gmail.com> Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-11-13Update packfile transfer protocol documentationLibravatar Scott Chacon3-41/+777
The current technical documentation for the packfile protocol is both sparse and incorrect. This documents the fetch-pack/upload-pack and send-pack/ receive-pack protocols much more fully. Add documentation from Shawn's upcoming http-protocol docs that is shared by the packfile protocol. protocol-common.txt describes ABNF notation amendments, refname rules and the packet line format. Add documentation on the various capabilities supported by the upload-pack and receive-pack protocols. protocol-capabilities.txt describes multi-ack, thin-pack, side-band[-64k], shallow, no-progress, include-tag, ofs-delta, delete-refs and report-status.

2009-05-25parse-opts: add OPT_FILENAME and transition builtinsLibravatar Stephen Boyd1-0/+5
Commit dbd0f5c (Files given on the command line are relative to $cwd, 2008-08-06) introduced parse_options_fix_filename() as a minimal fix. OPT_FILENAME is intended to be a more robust fix for the same issue. OPT_FILENAME and its associated enum OPTION_FILENAME are used to represent filename options within the parse options API. This option is similar to OPTION_STRING. If --no is prefixed to the option the filename is unset. If no argument is given and the default value is set, the filename is set to the default value. The difference is that the filename is prefixed with the prefix passed to parse_options() (or parse_options_start()). Update git-apply, git-commit, git-fmt-merge-msg, and git-tag to use OPT_FILENAME with their filename options. Also, rename parse_options_fix_filename() to fix_filename() as it is no longer extern.

2009-05-25parse-opts: prepare for OPT_FILENAMELibravatar Stephen Boyd1-2/+2
To give OPT_FILENAME the prefix, we pass the prefix to parse_options() which passes the prefix to parse_options_start() which sets the prefix member of parse_opts_ctx accordingly. If there isn't a prefix in the calling context, passing NULL will suffice. Signed-off-by: Stephen Boyd <bebarino@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-03-09parseopt: prevent KEEP_UNKNOWN and STOP_AT_NON_OPTION from being used togetherLibravatar René Scharfe1-1/+2
As suggested by Junio, disallow the flags PARSE_OPT_KEEP_UNKNOWN and PARSE_OPT_STOP_AT_NON_OPTION to be turned on at the same time, as a value of an unknown option could be mistakenly classified as a non-option, stopping the parser early. E.g.: git cmd --known --unknown value arg0 arg1 The parser should have stopped at "arg0", but it already stops at "value".

2009-01-06strbuf: instate cleanup rule in case of non-memory errorsLibravatar René Scharfe1-2/+9
Make all strbuf functions that can fail free() their memory on error if they have allocated it. They don't shrink buffers that have been grown, though. This allows for easier error handling, as callers only need to call strbuf_release() if A) the command succeeded or B) if they would have had to do so anyway because they added something to the strbuf themselves. Bonus hunk: document strbuf_readlink. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-11-23add strbuf_expand_dict_cb(), a helper for simple casesLibravatar René Scharfe1-0/+7
The new callback function strbuf_expand_dict_cb() can be used together with strbuf_expand() if there is only a small number of placeholders for static replacement texts. It expects its dictionary as an array of placeholder+value pairs as context parameter, terminated by an entry with the placeholder member set to NULL. The new helper is intended to aid converting the remaining calls of interpolate(). strbuf_expand() is smaller, more flexible and can be used to go faster than interpolate(), so it should replace the latter.

With the --graph option, the graph already outputs 'o' instead of '*' for boundary commits. Make it emit '<' or '>' when --left-right is specified. (This change also disables the '^' prefix for UNINTERESTING commits.
