2024-11-26credential_format(): also encode <host>[:<port>]Johannes Schindelin1-0/+1
An upcoming change wants to sanitize the credential password prompt where a URL is displayed that may potentially come from a `.gitmodules` file. To this end, the `credential_format()` function is employed. To sanitize the host name (and optional port) part of the URL, we need a new mode of the `strbuf_add_percentencode()` function because the current mode is both too strict and too lenient: too strict because it encodes `:`, `[` and `]` (which should be left unencoded in `<host>:<port>` and in IPv6 addresses), and too lenient because it does not encode invalid host name characters `/`, `_` and `~`. So let's introduce and use a new mode specifically to encode the host name and optional port part of a URI, leaving alpha-numerical characters, periods, colons and brackets alone and encoding all others. This only leads to a change of behavior for URLs that contain invalid host names. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2024-05-29strbuf: introduce strbuf_addstrings() to repeatedly add a stringGhanshyam Thakkar1-0/+5
In a following commit we are going to port code from "t/helper/test-sha256.c", t/helper/test-hash.c and "t/t0015-hash.sh" to a new "t/unit-tests/t-hash.c" file using the recently added unit test framework. To port code like: perl -e "$| = 1; print q{aaaaaaaaaa} for 1..100000;" we are going to need a new strbuf_addstrings() function that repeatedly adds the same string a number of times to a buffer. Such a strbuf_addstrings() function would already be useful in "json-writer.c" and "builtin/submodule-helper.c" as both of these files already have code that repeatedly adds the same string. So let's introduce such a strbuf_addstrings() function in "strbuf.{c,h}" and use it in both "json-writer.c" and "builtin/submodule-helper.c". We use the "strbuf_addstrings" name as this way strbuf_addstr() and strbuf_addstrings() would be similar for strings as strbuf_addch() and strbuf_addchars() for characters.

2024-03-12find multi-byte comment chars in unterminated buffersJeff King1-0/+1
As with the previous patch, we need to swap out single-byte matching for something like starts_with() to match all bytes of a multi-byte comment character. But for cases where the buffer is not NUL-terminated (and we instead have an explicit size or end pointer), it's not safe to use starts_with(), as it might walk off the end of the buffer. Let's introduce a new starts_with_mem() that does the same thing but also accepts the length of the "haystack" str and makes sure not to walk past it. Note that in most cases the existing code did not need a length check at all, since it was written in a way that knew we had at least one byte available (and that was all we checked). So I had to read each one to find the appropriate bounds. The one exception is sequencer.c's add_commented_lines(), where we can actually get rid of the length check. Just like starts_with(), our starts_with_mem() handles an empty haystack variable by not matching (assuming a non-empty prefix). A few notes on the implementation of starts_with_mem(): - it would be equally correct to take an "end" pointer (and indeed, many of the callers have this and have to subtract to come up with the length). I think taking a ptr/size combo is a more usual interface for our codebase, though, and has the added benefit that the function signature makes it harder to mix up the three parameters. - we could obviously build starts_with() on top of this by passing strlen(str) as the length. But it's possible that starts_with() is a relatively hot code path, and it should not pay that penalty (it can generally return an answer proportional to the size of the prefix, not the whole string). - it naively feels like xstrncmpz() should be able to do the same thing, but that's not quite true. If you pass the length of the haystack buffer, then strncmp() finds that a shorter prefix string is "less than" than the haystack, even if the haystack starts with the prefix. If you pass the length of the prefix, then you risk reading past the end of the haystack if it is shorter than the prefix. So I think we really do need a new function.

As part of our transition to multi-byte comment characters, let's take a NUL-terminated string pointer for strbuf_stripspace(), rather than a single character. We can continue to support its feature of ignoring comments by accepting a NULL pointer (as opposed to the current behavior of a NUL byte). All of the callers have to be adjusted, but they can all just pass comment_line_str (or NULL). Inside the function we detect comments by comparing the first byte of a line to the comment character. We'll adjust that to use starts_with(), which will match multiple bytes (though for now, of course, we still only allow a single byte, so it's academic).

2024-03-12strbuf: avoid shadowing global comment_line_char nameJeff King1-4/+4
Several comment-related strbuf functions take a comment_line_char parameter. There's also a global comment_line_char variable, which is closely related (most callers pass it in as this parameter). Let's avoid shadowing the global name. This makes it more obvious that we're not using the global value, and it will be especially helpful as we refactor the global in future patches (in particular, any macro trickery wouldn't work because the preprocessor doesn't respect scope). We'll use "comment_prefix". That should be descriptive enough, and as a bonus is more neutral with respect to the "char" type (since we'll eventually swap it out for a string).

2023-06-12strbuf: provide CRLF-aware helper to read until a specified delimiterPatrick Steinhardt1-0/+12
Many of our commands support reading input that is separated either via newlines or via NUL characters. Furthermore, in order to be a better cross platform citizen, these commands typically know to strip the CRLF sequence so that we also support reading newline-separated inputs on e.g. the Windows platform. This results in the following kind of awkward pattern: ``` struct strbuf input = STRBUF_INIT; while (1) { int ret; if (nul_terminated) ret = strbuf_getline_nul(&input, stdin); else ret = strbuf_getline(&input, stdin); if (ret) break; ... } ``` Introduce a new CRLF-aware helper function that can read up to a user specified delimiter. If the delimiter is `\n` the function knows to also strip CRLF, otherwise it will only strip the specified delimiter. This results in the following, much more readable code pattern: ``` struct strbuf input = STRBUF_INIT; while (strbuf_getdelim_strip_crlf(&input, stdin, delim) != EOF) { ... } ``` The new function will be used in a subsequent commit.

Change the initialization of "struct strbuf" changed in cbc0f81d96f (strbuf: use designated initializers in STRBUF_INIT, 2017-07-10) to omit specifying "alloc" and "len", as we do with other "alloc" and "len" (or "nr") in similar structs. Let's likewise omit the explicit initialization of all fields in the "struct ipc_client_connect_option" struct added in 59c7b88198a (simple-ipc: add win32 implementation, 2021-03-15). Do the same for a few other initializers, e.g. STRVEC_INIT and CACHE_DEF_INIT. Finally, start incrementally changing the same pattern in "t/helper/test-run-command.c".

2020-04-27credential: fix matching URLs with multiple levels in pathbrian m. carlson1-1/+6
46fd7b3900 ("credential: allow wildcard patterns when matching config", 2020-02-20) introduced support for matching credential helpers using urlmatch. In doing so, it introduced code to percent-encode the paths we get from the credential helper so that they could be effectively matched by the urlmatch code. Unfortunately, that code had a bug: it percent-encoded the slashes in the path, resulting in any URL path that contained multiple levels (i.e., a directory component) not matching. We are currently the only caller of the percent-encoding code and could simply change it not to encode slashes. However, we still want to encode slashes in the username component, so we need to have both behaviors available. So instead, let's add a flag to control encoding slashes, which is the behavior we want here, and use it when calling the code in this case. Add a test for credential helper URLs using multiple slashes in the path, which our test suite previously lacked, as well as one ensuring that we handle usernames with slashes gracefully. Since we're testing other percent-encoding handling, let's add one for non-ASCII UTF-8 characters as well.

2020-02-20credential: allow wildcard patterns when matching configbrian m. carlson1-0/+6
In some cases, a user will want to use a specific credential helper for a wildcard pattern, such as https://*.corp.example.com. We have code that handles this already with the urlmatch code, so let's use that instead of our custom code. Since the urlmatch code is a superset of our current matching in terms of capabilities, there shouldn't be any cases of things that matched previously that don't match now. However, in addition to wildcard matching, we now use partial path matching, which can cause slightly different behavior in the case that a helper applies to the prefix (considering path components) of the remote URL. While different, this is probably the behavior people were wanting anyway. Since we're using the urlmatch code, we need to encode the components we've gotten into a URL to match, so add a function to percent-encode data and format the URL with it. We now also no longer need to the custom code to match URLs, so let's remove it. Additionally, the urlmatch code always looks for the best match, whereas we want all matches for credential helpers to preserve existing behavior. Let's add an optional field, select_fn, that lets us control which items we want (in this case, all of them) and default it to the best-match code that already exists for other users.

strbuf_release leaves the strbuf in a valid, initialized state, so there is no need to call strbuf_init after it.

That strbuf_setlen writes to slopbuf has at least two implications: First, it's wrong in principle. Second, it might be hiding misuses which are just waiting to wreak havoc. Third, ThreadSanitizer detects a race when multiple threads write to slopbuf at roughly the same time, thus potentially making any more critical races harder to spot. Avoid writing to strbuf_slopbuf in strbuf_setlen. Let's instead assert on the first byte of slopbuf being '\0', since it helps ensure the promised invariant of buf[len] == '\0'. (We know that "len" was already 0, or someone has messed with "alloc". If someone has fiddled with the fields that much beyond the correct interface, they're on their own.) This is a function which is used in many places, possibly also in hot code paths. There are two branches in strbuf_setlen already, and we are adding a third and possibly a fourth (in the assert). In hot code paths, we hopefully reuse the buffer in order to avoid continous reallocations. Thus, after a start-up phase, we should always take the same path, which might help branch prediction, and we would never make the assert. If a hot code path continuously reallocates, we probably have bigger performance problems than this new safety-check. Simple measurements do not contradict this reasoning. 100000000 times resetting a buffer and adding the empty string takes 5.29/5.26 seconds with/without this patch (best of three). Releasing at every iteration yields 18.01/17.87. Adding a 30-character string instead of the empty string yields 5.61/5.58 and 17.28/17.28(!). This patch causes the git binary emitted by gcc 5.4.0 -O2 on my machine to grow from 11389848 bytes to 11497184 bytes, an increase of 0.9%. I also tried to piggy-back on the fact that we already check alloc, which should already tell us whether we are using the slopbuf: if (sb->alloc) { if (len > sb->alloc - 1) die("BUG: strbuf_setlen() beyond buffer"); sb->buf[len] = '\0'; } else { if (len) die("BUG: strbuf_setlen() beyond buffer"); assert(!strbuf_slopbuf[0]); } sb->len = len; That didn't seem to be much slower (5.38, 18.02, 5.70, 17.32 seconds), but it does introduce some minor code duplication. The resulting git binary was 11510528 bytes large (another 0.1% increase). Signed-off-by: Martin Ågren <martin.agren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-07-14strbuf: use designated initializers in STRBUF_INITJeff King1-1/+1
There are certain C99 features that might be nice to use in our code base, but we've hesitated to do so in order to avoid breaking compatibility with older compilers. But we don't actually know if people are even using pre-C99 compilers these days. One way to figure that out is to introduce a very small use of a feature, and see if anybody complains. The strbuf code is a good place to do this for a few reasons: - it always gets compiled, no matter which Makefile knobs have been tweaked. - it's very stable; this definition hasn't changed in a long time and is not likely to (so if we have to revert, it's unlikely to cause headaches) If this patch can survive a few releases without complaint, then we can feel more confident that designated initializers are widely supported by our user base. It also is an indication that other C99 features may be supported, but not a guarantee (e.g., gcc had designated initializers before C99 existed). And if we do get complaints, then we'll have gained some data and we can easily revert this patch. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-06-15strbuf: let strbuf_addftime handle %z and %Z itselfRené Scharfe1-2/+8
There is no portable way to pass timezone information to strftime. Add parameters for timezone offset and name to strbuf_addftime and let it handle the timezone-related format specifiers %z and %Z internally. Callers can opt out for %Z by passing NULL as timezone name. %z is always handled internally -- this helps on Windows, where strftime would expand it to a timezone name (same as %Z), in violation of POSIX. Modifiers are not handled, e.g. %Ez is still passed to strftime. Use an empty string as timezone name in show_date (the only current caller) for now because we only have the timezone offset in non-local mode. POSIX allows %Z to resolve to an empty string in case of missing information.

2017-03-02interpret_branch_name: allow callers to restrict expansionsJeff King1-1/+5
The interpret_branch_name() function converts names like @{-1} and @{upstream} into branch names. The expanded ref names are not fully qualified, and may be outside of the refs/heads/ namespace (e.g., "@" expands to "HEAD", and "@{upstream}" is likely to be in "refs/remotes/"). This is OK for callers like dwim_ref() which are primarily interested in resolving the resulting name, no matter where it is. But callers like "git branch" treat the result as a branch name in refs/heads/. When we expand to a ref outside that namespace, the results are very confusing (e.g., "git branch @" tries to create refs/heads/HEAD, which is nonsense). Callers can't know from the returned string how the expansion happened (e.g., did the user really ask for a branch named "HEAD", or did we do a bogus expansion?). One fix would be to return some out-parameters describing the types of expansion that occurred. This has the benefit that the caller can generate precise error messages ("I understood @{upstream} to mean origin/master, but that is a remote tracking branch, so you cannot create it as a local name"). However, out-parameters make the function interface somewhat cumbersome. Instead, let's do the opposite: let the caller tell us which elements to expand. That's easier to pass in, and none of the callers give more precise error messages than "@{upstream} isn't a valid branch name" anyway (which should be sufficient). The strbuf_branchname() function needs a similar parameter, as most of the callers access interpret_branch_name() through it. We can break the callers down into two groups: 1. Callers that are happy with any kind of ref in the result. We pass "0" here, so they continue to work without restrictions. This includes merge_name(), the reflog handling in add_pending_object_with_path(), and substitute_branch_name(). This last is what powers dwim_ref(). 2. Callers that have funny corner cases (mostly in git-branch and git-checkout). These need to make use of the new parameter, but I've left them as "0" in this patch, and will address them individually in follow-on patches.

2016-10-10link_alt_odb_entry: handle normalize_path errorsJeff King1-0/+8
When we add a new alternate to the list, we try to normalize out any redundant "..", etc. However, we do not look at the return value of normalize_path_copy(), and will happily continue with a path that could not be normalized. Worse, the normalizing process is done in-place, so we are left with whatever half-finished working state the normalizing function was in. Fortunately, this cannot cause us to read past the end of our buffer, as that working state will always leave the NUL from the original path in place. And we do tend to notice problems when we check is_directory() on the path. But you can see the nonsense that we feed to is_directory with an entry like: this/../../is/../../way/../../too/../../deep/../../to/../../resolve in your objects/info/alternates, which yields: error: object directory /to/e/deep/too/way//ects/this/../../is/../../way/../../too/../../deep/../../to/../../resolve does not exist; check .git/objects/info/alternates. We can easily fix this just by checking the return value. But that makes it hard to generate a good error message, since we're normalizing in-place and our input value has been overwritten by cruft. Instead, let's provide a strbuf helper that does an in-place normalize, but restores the original contents on error. This uses a second buffer under the hood, which is slightly less efficient, but this is not a performance-critical code path. The strbuf helper can also properly set the "len" parameter of the strbuf before returning. Just doing: normalize_path_copy(buf.buf, buf.buf); will shorten the string, but leave buf.len at the original length. That may be confusing to later code which uses the strbuf.

2016-01-15strbuf: introduce strbuf_getline_{lf,nul}()Junio C Hamano1-3/+15
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 Hamano1-0/+7
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.

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.

2015-01-16strbuf.h: integrate api-strbuf.txt documentationJeff King1-67/+390
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.

E.g. a signed tag "for-linus" can be created, and the integrator can run: $ git pull git://example.com/work.git/ for-linus This would allow the integrator to run "git verify-tag FETCH_HEAD" to validate the signed tag. Update fmt-merge-msg so that it pre-fills the merge message template with the body (but not signature) of the tag object to help the integrator write a better merge message, in the same spirit as the existing merge.log summary lines.

2011-04-27strbuf: clarify assertion in strbuf_setlen()René Scharfe1-5/+2
Commit a8f3e2219 introduced the strbuf_grow() call to strbuf_setlen() to make ensure that there was at least one byte available to write the mandatory trailing NUL, even for previously unallocated strbufs. Then b315c5c0 added strbuf_slopbuf for the same reason, only globally for all uses of strbufs. Thus the strbuf_grow() call can be removed now. This avoids readers of strbuf.h from mistakenly thinking that strbuf_setlen() can be used to extend a strbuf. The following assert() needs to be changed to cope with the fact that sb->alloc can now be zero, which is OK as long as len is also zero. As suggested by Junio, use the chance to convert it to a die() with a short explanatory message. The pattern of 'die("BUG: ...")' is already used in strbuf.c. This was the only assert() in strbuf.[ch], so assert.h doesn't have to be included anymore either.

2007-11-09--pretty=format: on-demand format expansionRené Scharfe1-0/+3
Some of the --pretty=format placeholders expansions are expensive to calculate. This is made worse by the current code's use of interpolate(), which requires _all_ placeholders are to be prepared up front. One way to speed this up is to check which placeholders are present in the format string and to prepare only the expansions that are needed. That still leaves the allocation overhead of interpolate(). Another way is to use a callback based approach together with the strbuf library to keep allocations to a minimum and avoid string copies. That's what this patch does. It introduces a new strbuf function, strbuf_expand(). The function takes a format string, list of placeholder strings, a user supplied function 'fn', and an opaque pointer 'context' to tell 'fn' what thingy to operate on. The function 'fn' is expected to accept a strbuf, a parsed placeholder string and the 'context' pointer, and append the interpolated value for the 'context' thingy, according to the format specified by the placeholder.

2007-09-29strbuf change: be sure ->buf is never ever NULL.Pierre Habouzit1-5/+5
For that purpose, the ->buf is always initialized with a char * buf living in the strbuf module. It is made a char * so that we can sloppily accept things that perform: sb->buf[0] = '\0', and because you can't pass "" as an initializer for ->buf without making gcc unhappy for very good reasons. strbuf_init/_detach/_grow have been fixed to trust ->alloc and not ->buf anymore. as a consequence strbuf_detach is _mandatory_ to detach a buffer, copying ->buf isn't an option anymore, if ->buf is going to escape from the scope, and eventually be free'd. API changes: * strbuf_setlen now always works, so just make strbuf_reset a convenience macro. * strbuf_detatch takes a size_t* optional argument (meaning it can be NULL) to copy the buffer's len, as it was needed for this refactor to make the code more readable, and working like the callers.

2007-09-20strbuf API additions and enhancements.Pierre Habouzit1-6/+11
Add strbuf_remove, change strbuf_insert: As both are special cases of strbuf_splice, implement them as such. gcc is able to do the math and generate almost optimal code this way. Add strbuf_swap: Exchange the values of its arguments. Use it in fast-import.c Also fix spacing issues in strbuf.h Signed-off-by: Pierre Habouzit <madcoder@debian.org>
2007-09-18Drop strbuf's 'eof' marker, and make read_line a first class citizen.Pierre Habouzit1-3/+2
read_line is now strbuf_getline, and is a first class citizen, it returns 0 when reading a line worked, EOF else. The ->eof marker was used non-locally by fast-import.c, mimic the same behaviour using a static int in "read_next_command", that now returns -1 on EOF, and avoids to call strbuf_getline when it's in EOF state. Also no longer automagically strbuf_release the buffer, it's counter intuitive and breaks fast-import in a very subtle way. Note: being at EOF implies that command_buf.len == 0.

2007-09-16New strbuf APIs: splice and attach.Pierre Habouzit1-0/+5
* strbuf_splice replace a portion of the buffer with another. * strbuf_attach replace a strbuf buffer with the given one, that should be malloc'ed. Then it enforces strbuf's invariants. If alloc > len, then this function has negligible cost, else it will perform a realloc, possibly with a cost. Also some style issues are fixed now.

* Add strbuf_rtrim to remove trailing spaces. * Add strbuf_insert to insert data at a given position. * Off-by one fix in strbuf_addf: strbuf_avail() does not counts the final \0 so the overflow test for snprintf is the strict comparison. This is not critical as the growth mechanism chosen will always allocate _more_ memory than asked, so the second test will not fail. It's some kind of miracle though. * Add size extension hints for strbuf_init and strbuf_read. If 0, default applies, else: + initial buffer has the given size for strbuf_init. + first growth checks it has at least this size rather than the default 8192.

2007-09-06Rework strbuf API and semantics.Pierre Habouzit1-2/+84
The gory details are explained in strbuf.h. The change of semantics this patch enforces is that the embeded buffer has always a '\0' character after its last byte, to always make it a C-string. The offs-by-one changes are all related to that very change. A strbuf can be used to store byte arrays, or as an extended string library. The `buf' member can be passed to any C legacy string function, because strbuf operations always ensure there is a terminating \0 at the end of the buffer, not accounted in the `len' field of the structure. A strbuf can be used to generate a string/buffer whose final size is not really known, and then "strbuf_detach" can be used to get the built buffer, and keep the wrapping "strbuf" structure usable for further work again. Other interesting feature: strbuf_grow(sb, size) ensure that there is enough allocated space in `sb' to put `size' new octets of data in the buffer. It helps avoiding reallocating data for nothing when the problem the strbuf helps to solve has a known typical size.

2005-04-25[PATCH] Introduce diff-tree-helper.Junio C Hamano1-0/+13
This patch introduces a new program, diff-tree-helper. It reads output from diff-cache and diff-tree, and produces a patch file. The diff format customization can be done the same way the show-diff uses; the same external diff interface introduced by the previous patch to drive diff from show-diff is used so this is not surprising. It is used like the following examples: $ diff-cache --cached -z <tree> | diff-tree-helper -z -R paths... $ diff-tree -r -z <tree1> <tree2> | diff-tree-helper -z paths... - As usual, the use of the -z flag is recommended in the script to pass NUL-terminated filenames through the pipe between commands. - The -R flag is used to generate reverse diff. It does not matter for diff-tree case, but it is sometimes useful to get a patch in the desired direction out of diff-cache. - The paths parameters are used to restrict the paths that appears in the output. Again this is useful to use with diff-cache, which, unlike diff-tree, does not take such paths restriction parameters.
