The recent +security fix that went to 2.2.1 and older maintenance tracks is also +contained in this update. + + +Updates since v2.2 +------------------ + +Ports + + * Recent gcc toolchain on Cygwin started throwing compilation warning, + which has been squelched. + + * A few updates to build on platforms that lack tv_nsec, + clock_gettime, CLOCK_MONOTONIC and HMAC_CTX_cleanup (e.g. older + RHEL) have been added. + + +UI, Workflows & Features + + * It was cumbersome to use "GIT_SSH" mechanism when the user wanted + to pass an extra set of arguments to the underlying ssh. A new + environment variable GIT_SSH_COMMAND can be used for this. + + * A request to store an empty note via "git notes" meant to remove + note from the object but with --allow-empty we will store a + (surprise!) note that is empty. + + * "git interpret-trailers" learned to properly handle the + "Conflicts:" block at the end. + + * "git am" learned "--message-id" option to copy the message ID of + the incoming e-mail to the log message of resulting commit. + + * "git clone --reference=<over there>" learned the "--dissociate" + option to go with it; it borrows objects from the reference object + store while cloning only to reduce network traffic and then + dissociates the resulting clone from the reference by performing + local copies of borrowed objects. + + * "git send-email" learned "--transfer-encoding" option to force a + non-fault Content-Transfer-Encoding header (e.g. base64). + + * "git send-email" normally identifies itself via X-Mailer: header in + the message it sends out. A new command line flag --no-xmailer + allows the user to squelch the header. + + * "git push" into a repository with a working tree normally refuses + to modify the branch that is checked out. The command learned to + optionally do an equivalent of "git reset --hard" only when there + is no change to the working tree and the index instead, which would + be useful to "deploy" by pushing into a repository. + + * "git new-workdir" (in contrib/) can be used to populate an empty + and existing directory now. + + * Credential helpers are asked in turn until one of them give + positive response, which is cumbersome to turn off when you need to + run Git in an automated setting. The credential helper interface + learned to allow a helper to say "stop, don't ask other helpers." + Also GIT_TERMINAL_PROMPT environment can be set to false to disable + our built-in prompt mechanism for passwords. + + * "git branch -d" (delete) and "git branch -m" (move) learned to + honor "-f" (force) flag; unlike many other subcommands, the way to + force these have been with separate "-D/-M" options, which was + inconsistent. + + * "diff-highlight" filter (in contrib/) allows its color output to be + customized via configuration variables. + + * "git imap-send" learned to take "-v" (verbose) and "-q" (quiet) + command line options. + + * "git remote add $name $URL" is now allowed when "url.$URL.insteadOf" + is already defined. + + * "git imap-send" now can be built to use cURL library to talk to + IMAP servers (if the library is recent enough, of course). + This allows you to use authenticate method other than CRAM-MD5, + among other things. + + * "git imap-send" now allows GIT_CURL_VERBOSE environment variable to + control the verbosity when talking via the cURL library. + + * The prompt script (in contrib/) learned to optionally hide prompt + when in an ignored directory by setting GIT_PS1_HIDE_IF_PWD_IGNORED + shell variable. + + +Performance, Internal Implementation, Development Support etc. + + * Earlier we made "rev-list --object-edge" more aggressively list the + objects at the edge commits, in order to reduce number of objects　 + fetched into a shallow repository, but the change affected cases + other than "fetching into a shallow repository" and made it + unusably slow (e.g. fetching into a normal repository should not + have to suffer the overhead from extra processing). Limit it to a + more specific case by introducing --objects-edge-aggressive, a new + option to rev-list. + + * Squelched useless compiler warnings on Mac OS X regarding the + crypto API. + + * The procedure to generate unicode table has been simplified. + + * Some filesystems assign filemodes in a strange way, fooling then + automatic "filemode trustability" check done during a new + repository creation. The initialization codepath has been hardened + against this issue. + + * The codepath in "git remote update --prune" to drop many refs has + been optimized. + + * The API into get_merge_bases*() family of functions was easy to + misuse, which has been corrected to make it harder to do so. + + * Long overdue departure from the assumption that S_IFMT is shared by + everybody made in 2005, which was necessary to port to z/OS. + + * "git push" and "git fetch" did not communicate an overlong refname + correctly. Now it uses 64kB sideband to accommodate longer ones. + + * Recent GPG changes the keyring format and drops support for RFC1991 + formatted signatures, breaking our existing tests. + + * "git-prompt" (in contrib/) used a variable from the global scope, + possibly contaminating end-user's namespace. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v2.2 +---------------- + +Unless otherwise noted, all the fixes since v2.2 in the maintenance +track are contained in this release (see the maintenance releases' +notes for details). + + * "git http-push" over WebDAV (aka dumb http-push) was broken in + v2.2.2 when parsing a symbolic ref, resulting in a bogus request + that gets rejected by recent versions of cURL library. + (merge f6786c8 jk/http-push-symref-fix later to maint). + + * The logic in "git bisect bad HEAD" etc. to avoid forcing the test + of the common ancestor of bad and good commits was broken. + (merge 07913d5 cc/bisect-rev-parsing later to maint). + + * "git checkout-index --temp=$target $path" did not work correctly + for paths outside the current subdirectory in the project. + (merge 74c4de5 es/checkout-index-temp later to maint). + + * The report from "git checkout" on a branch that builds on another + local branch by setting its branch.*.merge to branch name (not a + full refname) incorrectly said that the upstream is gone. + (merge 05e7368 jc/checkout-local-track-report later to maint). + + * With The git-prompt support (in contrib/), using the exit status of + the last command in the prompt, e.g. PS1='$(__git_ps1) $?

The second parameter can be zero or a bigger - number to allocate memory, in case you want to prevent further reallocs. - -`strbuf_release`:: - - Release a string buffer and the memory it used. You should not use the - string buffer after using this function, unless you initialize it again. - -`strbuf_detach`:: - - Detach the string from the strbuf and returns it; you now own the - storage the string occupies and it is your responsibility from then on - to release it with `free(3)` when you are done with it. - -`strbuf_attach`:: - - Attach a string to a buffer. You should specify the string to attach, - the current length of the string and the amount of allocated memory. - The amount must be larger than the string length, because the string you - pass is supposed to be a NUL-terminated string. This string _must_ be - malloc()ed, and after attaching, the pointer cannot be relied upon - anymore, and neither be free()d directly. - -`strbuf_swap`:: - - Swap the contents of two string buffers. - -* Related to the size of the buffer - -`strbuf_avail`:: - - Determine the amount of allocated but unused memory. - -`strbuf_grow`:: - - Ensure that at least this amount of unused memory is available after - `len`. This is used when you know a typical size for what you will add - and want to avoid repetitive automatic resizing of the underlying buffer. - This is never a needed operation, but can be critical for performance in - some cases. - -`strbuf_setlen`:: - - Set the length of the buffer to a given value. This function does *not* - allocate new memory, so you should not perform a `strbuf_setlen()` to a - length that is larger than `len + strbuf_avail()`. `strbuf_setlen()` is - just meant as a 'please fix invariants from this strbuf I just messed - with'. - -`strbuf_reset`:: - - Empty the buffer by setting the size of it to zero. - -* Related to the contents of the buffer - -`strbuf_trim`:: - - Strip whitespace from the beginning and end of a string. - Equivalent to performing `strbuf_rtrim()` followed by `strbuf_ltrim()`. - -`strbuf_rtrim`:: - - Strip whitespace from the end of a string. - -`strbuf_ltrim`:: - - Strip whitespace from the beginning of a string. - -`strbuf_reencode`:: - - Replace the contents of the strbuf with a reencoded form. 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/api-string-list.txt b/Documentation/technical/api-string-list.txt index d51a6579c8..c08402b12e 100644 --- a/Documentation/technical/api-string-list.txt +++ b/Documentation/technical/api-string-list.txt @@ -29,7 +29,7 @@ member (you need this if you add things later) and you should set the `unsorted_string_list_has_string` and get it from the list using `string_list_lookup` for sorted lists. -.
