Returns -1 - on error, 0 on success. - -`strbuf_tolower`:: - - Lowercase each character in the buffer using `tolower`. - -`strbuf_cmp`:: - - Compare two buffers. Returns an integer less than, equal to, or greater - than zero if the first buffer is found, respectively, to be less than, - to match, or be greater than the second buffer. - -* Adding data to the buffer - -NOTE: All of the functions in this section will grow the buffer as necessary. -If they fail for some reason other than memory shortage and the buffer hadn't -been allocated before (i.e. the `struct strbuf` was set to `STRBUF_INIT`), -then they will free() it. - -`strbuf_addch`:: - - Add a single character to the buffer. - -`strbuf_addchars`:: - - Add a character the specified number of times to the buffer. - -`strbuf_insert`:: - - Insert data to the given position of the buffer. The remaining contents - will be shifted, not overwritten. - -`strbuf_remove`:: - - Remove given amount of data from a given position of the buffer. - -`strbuf_splice`:: - - Remove the bytes between `pos..pos+len` and replace it with the given - data. - -`strbuf_add_commented_lines`:: - - Add a NUL-terminated string to the buffer. Each line will be prepended - by a comment character and a blank. - -`strbuf_add`:: - - Add data of given length to the buffer. - -`strbuf_addstr`:: - -Add a NUL-terminated string to the buffer. -+ -NOTE: This function will *always* be implemented as an inline or a macro -that expands to: -+ ----- -strbuf_add(..., s, strlen(s)); ----- -+ -Meaning that this is efficient to write things like: -+ ----- -strbuf_addstr(sb, "immediate string"); ----- - -`strbuf_addbuf`:: - - Copy the contents of another buffer at the end of the current one. - -`strbuf_adddup`:: - - Copy part of the buffer from a given position till a given length to the - end of the buffer. - -`strbuf_expand`:: - - This function can be used to expand a format string containing - placeholders. To that end, it parses the string and calls the specified - function for every percent sign found. -+ -The callback function is given a pointer to the character after the `%` -and a pointer to the struct strbuf. It is expected to add the expanded -version of the placeholder to the strbuf, e.g. to add a newline -character if the letter `n` appears after a `%`. The function returns -the length of the placeholder recognized and `strbuf_expand()` skips -over it. -+ -The format `%%` is automatically expanded to a single `%` as a quoting -mechanism; callers do not need to handle the `%` placeholder themselves, -and the callback function will not be invoked for this placeholder. -+ -All other characters (non-percent and not skipped ones) are copied -verbatim to the strbuf. If the callback returned zero, meaning that the -placeholder is unknown, then the percent sign is copied, too. -+ -In order to facilitate caching and to make it possible to give -parameters to the callback, `strbuf_expand()` passes a context pointer, -which can be used by the programmer of the callback as she sees fit. - -`strbuf_expand_dict_cb`:: - - Used as callback for `strbuf_expand()`, expects an array of - struct strbuf_expand_dict_entry as context, i.e. pairs of - placeholder and replacement string. The array needs to be - terminated by an entry with placeholder set to NULL. - -`strbuf_addbuf_percentquote`:: - - Append the contents of one strbuf to another, quoting any - percent signs ("%") into double-percents ("%%") in the - destination. This is useful for literal data to be fed to either - strbuf_expand or to the *printf family of functions. - -`strbuf_humanise_bytes`:: - - Append the given byte size as a human-readable string (i.e. 12.23 KiB, - 3.50 MiB). - -`strbuf_addf`:: - - Add a formatted string to the buffer. - -`strbuf_commented_addf`:: - - Add a formatted string prepended by a comment character and a - blank to the buffer. - -`strbuf_fread`:: - - Read a given size of data from a FILE* pointer to the buffer. -+ -NOTE: The buffer is rewound if the read fails. If -1 is returned, -`errno` must be consulted, like you would do for `read(3)`. -`strbuf_read()`, `strbuf_read_file()` and `strbuf_getline()` has the -same behaviour as well. - -`strbuf_read`:: - - Read the contents of a given file descriptor. The third argument can be - used to give a hint about the file size, to avoid reallocs. - -`strbuf_read_file`:: - - Read the contents of a file, specified by its path. The third argument - can be used to give a hint about the file size, to avoid reallocs. - -`strbuf_readlink`:: - - Read the target of a symbolic link, specified by its path. The third - argument can be used to give a hint about the size, to avoid reallocs. - -`strbuf_getline`:: - - Read a line from a FILE *, overwriting the existing contents - of the strbuf. The second argument specifies the line - terminator character, typically `'\n'`. - Reading stops after the terminator or at EOF. The terminator - is removed from the buffer before returning. Returns 0 unless - there was nothing left before EOF, in which case it returns `EOF`. - -`strbuf_getwholeline`:: - - Like `strbuf_getline`, but keeps the trailing terminator (if - any) in the buffer. - -`strbuf_getwholeline_fd`:: - - Like `strbuf_getwholeline`, but operates on a file descriptor. - It reads one character at a time, so it is very slow. Do not - use it unless you need the correct position in the file - descriptor. - -`strbuf_getcwd`:: - - Set the buffer to the path of the current working directory. - -`strbuf_add_absolute_path` - - Add a path to a buffer, converting a relative path to an - absolute one in the process. Symbolic links are not - resolved. - -`stripspace`:: - - Strip whitespace from a buffer. The second parameter controls if - comments are considered contents to be removed or not. - -`strbuf_split_buf`:: -`strbuf_split_str`:: -`strbuf_split_max`:: -`strbuf_split`:: - - Split a string or strbuf into a list of strbufs at a specified - terminator character. The returned substrings include the - terminator characters. Some of these functions take a `max` - parameter, which, if positive, limits the output to that - number of substrings. - -`strbuf_list_free`:: - - Free a list of strbufs (for example, the return values of the - `strbuf_split()` functions). - -`launch_editor`:: - - Launch the user preferred editor to edit a file and fill the buffer - with the file's contents upon the user completing their editing. The - third argument can be used to set the environment which the editor is - run in. If the buffer is NULL the editor is launched as usual but the - file's contents are not read into the buffer upon completion. diff --git a/Documentation/technical/protocol-capabilities.txt b/Documentation/technical/protocol-capabilities.txt index 6d5424c1bd..4f8a7bfb4c 100644 --- a/Documentation/technical/protocol-capabilities.txt +++ b/Documentation/technical/protocol-capabilities.txt @@ -18,8 +18,9 @@ was sent.

Release Notes +====================== + +Updates since v2.3 +------------------ + +Ports + + * Our default I/O size (8 MiB) for large files was too large for some + platforms with smaller SSIZE_MAX, leading to read(2)/write(2) + failures. + + * We did not check the curl library version before using + CURLOPT_PROXYAUTH feature that may not exist. + + +UI, Workflows & Features + + * The command usage info strings given by "git cmd -h" and in + documentation have been tweaked for consistency. + + * The "sync" subcommand of "git p4" now allows users to exclude + subdirectories like its "clone" subcommand does. + + * "git log --invert-grep --grep=WIP" will show only commits that do + not have the string "WIP" in their messages. + + * "git push" has been taught a "--atomic" option that makes push to + update more than one ref an "all-or-none" affair. + + * Extending the "push to deploy" added in 2.3, the behaviour of "git + push" when updating the branch that is checked out can now be + tweaked by push-to-checkout hook. + + * Using environment variable LANGUAGE and friends on the client side, + HTTP-based transports now send Accept-Language when making requests. + + * "git send-email" used to accept a mistaken "y" (or "yes") as an + answer to "What encoding do you want to use [UTF-8]? " without + questioning. Now it asks for confirmation when the answer looks + too short to be a valid encoding name. + + +Performance, Internal Implementation, Development Support etc. + + * Implementation of N_() macro has been updated slightly to help us + detect mistakes. + + * Implementation of "reflog expire" has been restructured to fit the + reflogs better with the recently updated ref API. + + * The transport-helper did not give transport options such as + verbosity, progress, cloning, etc. to import and export based + helpers, like it did for fetch and push based helpers, robbing them + the chance to honor the wish of the end-users better. + + * The tests that wanted to see that file becomes unreadable after + running "chmod a-r file", and the tests that wanted to make sure it + is not run as root, we used "can we write into the / directory?" as + a cheap substitute, but on some platforms that is not a good + heuristics. The tests and their prerequisites have been updated to + check what they really require. + (merge f400e51 jk/sanity later to maint). + + * The strbuf API was explained between the API documentation and in + the header file. Move missing bits to strbuf.h so that programmers + can check only one place for all necessary information. + + * The error handling functions and conventions are now documented in + the API manual. + + * Optimize attribute look-up, mostly useful in "git grep" on a + project that does not use many attributes, by avoiding it when we + (should) know that the attributes are not defined in the first + place. + + * Typofix in comments. + (merge ef2956a ak/git-pm-typofix later to maint). + + * Code clean-up. + (merge 0b868f0 sb/hex-object-name-is-at-most-41-bytes-long later to maint). + (merge

all the fixes since v2.3 in the maintenance +track are contained in this release (see the maintenance releases' +notes for details). + + * "git blame HEAD -- missing" failed to correctly say "HEAD" when it + tried to say "No such path 'missing' in HEAD". + (merge a46442f jk/blame-commit-label later to maint). + + * "git rerere" (invoked internally from many mergy operations) did + not correctly signal errors when told to update the working tree + files and failed to do so for whatever reason. + (merge 89ea903 jn/rerere-fail-on-auto-update-failure later to maint). + + * Setting diff.submodule to 'log' made "git format-patch" produce + broken patches. + (merge 339de50 dk/format-patch-ignore-diff-submodule later to maint). + + * After attempting and failing a password-less authentication + (e.g. kerberos), libcURL refuses to fall back to password based + Basic authentication without a bit of help/encouragement. + (merge 4dbe664 bc/http-fallback-to-password-after-krb-fails later to

that is always true has been fixed. + (merge 94ee8e2 jk/remote-curl-an-array-in-struct-cannot-be-null later to maint). + + * The documentation incorrectly said that C(opy) and R(ename) are the + only

--whitespace=fix" used to under-allocate the memory when + the fix resulted in a longer text than the original patch. + (merge 407a792 jc/apply-ws-fix-expands later to maint). + + * The interactive "show a list and let the user choose from it" + interface "add -i" used showed and prompted to the user even when + the candidate list was empty, against which the only "choice" the + user could have
