Shawn O. Pearce ffb55c53 2008-12-30T22:29:04 Rename the path of the objects directory to be more specific We're likely to add additional path data, like the path of the refs or the path to the config file into the git_odb structure, as it may grow into the repository wrapper. Changing the name of the objects directory reference makes it more clear should we later add something else. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Shawn O. Pearce 4c67e2e9 2008-12-30T22:25:30 Change git_odb__read_packed to return ENOTFOUND until implemented We didn't search for the object, so we cannot possibly promise it to the caller of git_odb_read(). Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Shawn O. Pearce 064301cc 2008-12-30T22:07:56 Fix size_t snprintf warning by using PRIuPTR format macro This is the correct C99 format code for the size_t type when passed as an argument to the *printf family. If the platform doesn't define it, we assume %lu and just cross our fingers that its the proper setting for a size_t on this system. On most sane platforms, "unsigned long" is the underlying type of "size_t". Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Shawn O. Pearce a1d34bc0 2008-12-30T21:49:38 Support building on Mac OS X by using pthread_getspecific for TLS The Mach-O format does not permit gcc to implement the __thread TLS specification, so we must instead emulate it using a single int cell allocated from memory and stored inside of the thread specific data associated with the current pthread. What makes this tricky is git_errno must be a valid lvalue, so we really need to return a pointer to the caller and deference it as part of the git_errno macro. The GCC-specific __attribute__((constructor)) extension is used to ensure the pthread_key_t is allocated before any Git functions are executed in the library, as this is necessary to access our thread specific storage.

Ramsay Jones 007e0753 2008-12-27T18:58:25 Add some routines for SHA1 hash computation [sp: Changed signature for output to use git_oid, and added a test case to verify an allocated git_hash_ctx can be reinitialized and reused.] Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Ramsay Jones 42fd40db 2008-12-27T18:56:16 Fix a bug in gitfo_read_file() In particular, when asked to read an empty file, this function calls malloc() with a zero size allocation request. Standard C says that the behaviour of malloc() in this case is implementation defined. [C99, 7.20.3 says "... If the size of the space requested is zero, the behavior is implementation-defined: either a null pointer is returned, or the behavior is as if the size were some nonzero value, except that the returned pointer shall not be used to access an object."] Finesse the issue by over-allocating by one byte. Setting the extra byte to '\0' may also provide a useful sentinel for text files. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

Ramsay Jones 75d58430 2008-12-18T22:56:14 Add a file reading routine along with an io buffer type In particular, the gitfo_read_file() routine can be used to slurp the complete file contents into an gitfo_buf structure. The buffer content will be allocated by malloc() and may be released by the gitfo_free_buf() routine. The io buffer type can be initialised on the stack with the GITFO_BUF_INIT macro.

Ramsay Jones b3be0fc7 2008-12-03T23:54:47 Fix an "implicit function definition" warning on cygwin In particular, the warning relates to malloc(), which is declared in <stdlib.h>.

Ramsay Jones 5ee2fe77 2008-12-03T23:53:55 Add a GIT_PATH_MAX constant The PATH_MAX symbol is often, but not always, defined in the <limits.h> header. In particular, on cygwin you need to include this header to avoid a compilation error. However, some systems define PATH_MAX to be something as small as 256, which POSIX is happy to allow, while others allow much larger values. In general it can vary from one filesystem to another. In order to avoid the vagaries of different systems, define our own symbol. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

Andreas Ericsson ea790f33 2008-11-29T15:34:20 Add a dirent walker to the fileops API Since at least MS have something like GetFirstDirEnt() and GetNextDirEnt() (presumably with superior performance), we can let MS hackers add support for a dirent walker using that API instead, while we stick with the posix-style readdir() calls.

Andreas Ericsson 4188d28f 2008-11-29T15:28:12 Add an io caching layer to the gitfo api The idea is taken from Junio's work in read-cache.c, where it's used for writing out the index without tap-dancing on the poor harddrive. Since it's almost certainly useful for cached writing of packfiles too, we turn it into a generic API, making it perfectly simple to reuse it later. gitfo_write_cached() has the same contract as gitfo_write(), it returns GIT_SUCCESS if all bytes are successfully written (or were at least buffered for later writing), and <0 if an error occurs during buffer writing.

Andreas Ericsson ec250c6e 2008-11-23T22:37:55 Remove config.h and make fileops an internal API Since it doesn't make sense to make the disk access stuff portable *AND* public (that's a job for each application imo), we can take a shortcut and just support unixy stuff for now and get away with coding most of it as macros. Since we go with an internal API for starters and only provide higher-level API's to the libgit users, we'll be ok with this approach.

Andreas Ericsson c6ebb4a9 2008-11-22T15:17:17 Remove license top-comment from public header files Since it's being added when we install the headers anyway, we might as well get rid of it. If anything, we should point coders to the COPYING file in the project's root directory instead of duplicating the same (large-ish) text everywhere.

Andreas Ericsson ae234862 2008-11-18T22:20:15 Add an embryo of a TLS-aware error handling system This adds the per-thread global variable git_errno to the system, which callers can examine to get information about an error. Two helper functions are added to reduce LoC-count for the library code itself. Also, some exceptions are made for running sparse on GIT_TLS definitions, since it doesn't grok thread-local variables at all. Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Shawn O.

Andreas Ericsson 4f0adcd0 2008-11-18T21:28:55 Get rid of GIT__PRIVATE macro Using it in the first place means something's wrong. This patch replaces it with an internal header which carries the previously "protected" code instead. Internal source-files simply include "commit.h" and they're done.

Andreas Ericsson 36f0f61f 2008-11-18T19:06:25 Add compiler/platform agnostic thread-local storage It doesn't cover all cases, but we can work on those as we go along. For now, gcc, MSVC++, Intel C/C++, IBM XL C/C++, Sun Studio C/C++ and Borland C++ Builder are the supported compilers (although we boldly assume that they all are of a recent enough version to support thread-local storage). This is intended to be used in upcoming patches that implement graceful (but TLS-dependant) error-handling in the library. As an added bonus, we also bring the online_cpus() function from git.git to detect the number of usable cpu's. Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Shawn O.

Andreas Ericsson d4043ee9 2008-11-18T01:18:52 Move public headers to src/git It's arguably smoother to keep them close to the source, as that's where one's working when modifying them. More importantly, though, is the ability to use private headers in the src/ dir that simply include "git/$samename.h" to get to the public API at the same time.

Andreas Ericsson 1b9e92c7 2008-11-18T01:02:27 s/git_revp/git_revpool/ git_revp is something I personally can't stop pronouncing "rev pointer". I'm sure others would suffer the same problem. Also, rename the git_revp_ sub-api "gitrp_". This is the first of many such renames, primarily done to prevent extreme inflation in the "git_" namespace, which we'd like to reserve for a higher-level API. While we're at it, we remove the noise-char "c" from a lot of functions. Since revision walking is all about commits, the common case should be that we're dealing with commits. Exceptions can get a more mnemonic description as needed. Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Andreas Ericsson dff79e27 2008-11-18T00:59:36 Rename "git_sobj" "git_obj" The 's' never really made sense, since it's not a "small" object at all, but rather a plain object.

Shawn O. Pearce 3e9e6909 2008-11-03T17:14:25 Redefine git_fread, git_fwrite to transfer the whole unit We never want to accept a short read or a short write when transferring data to or from a local file.

Shawn O. Pearce b7c891c6 2008-11-03T17:31:16 Add git_oid_cpy, git_oid_cmp as inline functions These are easily built off the standard C library functions memcpy and memcmp. By marking these inline we stand a good chance of the C compiler replacing the entire thing with tight machine code, because many compilers will actually inline a memcmp or memcpy when the 3rd argument (the size) is a constant value.

Shawn O. Pearce 3e89665e 2008-10-31T18:34:02 Scratch the git_revp_attr configuration of a git_revp This isn't the best idea I've head. Pierre Habouzit was suggesting a technique of assigning a unique integer to each commit and then allocating storage out of auxiliary pools, using the commit's unique integer to index into any auxiliary pool in constant time. This way both applications and the library can efficiently attach arbitrary data onto a commit, such as rewritten parents, or flags, and have them disconnected from the main object hash table.
