Vicent Marti 088a731f 2010-06-09T14:54:22 Fixed memory leaks in test suite Created commit objects in t0401-parse weren't being freed properly. Updated the API documentation to note that commit objects are owned by the revision pool and should not be freed manually. The parents list of each commit was being freed twice after each test. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 58b0cbea 2010-07-10T12:14:30 Actually free all commits when freeing a commit pool Previously the objects table was being freed, but not the actuall commits. All git_commit objects are freed and hence invalidated when freeing the git_rp object they belong to. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 3cd8b687 2010-07-10T12:08:04 Fix warning in util.h (signed vs unsigned comparison) This fix had been delayed by Ramsay because on 32-bit systems it highlights the fact that off_t is set to an invalid value. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Ramsay Jones ca3939e6 2010-06-03T22:28:30 msvc: Disable a level 4 warning and change -W3 to -W4 Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk>
Ramsay Jones 4386ee2a 2010-06-05T21:09:03 Add a 'git__' prefix to the block-sha1 functions This reduces the global namespace pollution. These functions were the only remaining external symbols (with the exception of an PPC_SHA1 build) which did not start with 'git', and since these are private library symbols the 'git__' prefix is appropriate.

Ramsay Jones bc874e11 2010-05-13T20:53:58 msvc: Select the "fast" definition of the {get,put}_be32() macros On Intel machines, the msvc compiler defines the CPU architecture macros _M_IX86 and _M_X64 (equivalent to __i386__ and __x86_64__ respectively). Use these macros in the pre-processor expression to select the "fast" definition of the {get,put}_be32() macros. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk>
Ramsay Jones 552e23ba 2010-06-02T19:16:28 Fix a bug in the git_oid_to_string() function When git_oid_to_string() was passed a buffer size larger than GIT_OID_HEXSZ+1, the function placed the c-string NUL char at the wrong position.

Ramsay Jones 28f98329 2010-06-01T19:37:10 Fix inconsistent definition of off_t on Linux In order to avoid inconsistent definitions of type off_t, all compilation units should include the "common.h" header file before certain system headers (those which directly or indirectly lead to the definition of off_t). The "common.h" header contains the definition of _FILE_OFFSET_BITS to select 64-bit file offsets. The symptom of this inconsistency, while compiling with -Wextra, is the following warning: In file included from src/common.h:50, from src/commit.c:28: src/util.h: In function git__is_sizet: src/util.h:41: warning: comparison between signed and unsigned In order to fix the problem, we simply remove the #include <time.h> statement at the head of src/commit.c.

Ramsay Jones c1b62b2e 2010-06-01T19:35:49 Fix a "dereference of type-punned pointer" compiler warning gcc (4.4.0) issues the following warning: src/revobject.c:33: warning: dereferencing type-punned pointer \ will break strict-aliasing rules We suppress the warning by copying the first 4 bytes from the oid structure into an 'unsigned int' using memcpy(). This will also fix any potential alignment issues on certain platforms. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Andreas Ericsson <ae@op5.se>
Ramsay Jones 84b9cec7 2010-06-01T19:33:57 Fix sparse warnings: "symbol not declared. Should it be static?" In particular, sparse issues the following warnings: src/revobject.c:29:14: warning: symbol 'max_load_factor' was \ not declared. Should it be static? src/revobject.c:31:14: warning: symbol 'git_revpool_table__hash' was \ not declared. Should it be static? In order to suppress these warnings, we simply declare them as static, since they are not (currently) referenced outside of this file. In the case of max_load_factor, this is probably correct. However, this may not be appropriate for git_revpool_table__hash(), given how it is named. So, this should either be re-named to reflect it's non-external status, or a declaration needs to be added to the revobject.h header file.

Ramsay Jones ee1765e5 2010-06-01T19:32:41 Fix sparse warnings: "Using plain integer as NULL pointer" In order to suppress this warning, we could simply replace the constant 0 with NULL.

Ramsay Jones 4e0d6d86 2010-06-01T19:30:29 msvc: Fix an "conversion, loss of data" compiler warning In particular, the compiler issues the following warning: src/revwalk.c(61) : warning C4244: '=' : conversion from \ 'unsigned int' to 'unsigned char', possible loss of data In order to suppress the warning, we change the type of the sorting "enum" field of the git_revpool structure to be consistent with the sort_mode parameter of the gitrp_sorting() function. Note that if the size of the git_revpool structure is an issue, then we could change the type of the sort_mode parameter instead.

Ramsay Jones 5440906f 2010-06-01T19:29:15 msvc: Fix some compiler warnings In particular, the compiler issues the following warnings: src/revobject.c(29) : warning C4305: 'initializing' : truncation \ from 'double' to 'const float' src/revobject.c(56) : warning C4244: '=' : conversion from \ 'const float' to 'unsigned int', possible loss of data src/revobject.c(149) : warning C4244: '=' : conversion from \ 'const float' to 'unsigned int', possible loss of data In order to suppress the warnings we change the type of max_load_factor to double, rather than change the initialiser to 0.65f, and cast the result type of the expressions to 'unsigned int' as expected by the assignment operators. Note that double should be able to represent all unsigned int values without loss. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Andreas Ericsson <ae@op5.se>

Vicent Marti c5696427 2010-05-22T23:21:10 Add 'git_revpool_object' and 'git_revpool_table' structures. All the objects which will will be eventually transversable from a revision pool (commits, trees, etc) now inherit from the 'git_revpool_object' structure which identifies them with their own OID. Furthermore, the 'git_revpool_table' and related functions have been added, which allow for constant time lookup (hash table) of the loaded revpool objects based on their OID.

Vicent Marti 08d5d000 2010-05-18T20:55:19 Add commit parents to parsed commits and commit lists to the revpool. Basic support for iterating the revpool. The following functions of the revwalk API have been partially implemented: void gitrp_reset(git_revpool *pool); void gitrp_push(git_revpool *pool, git_commit *commit); void gitrp_prepare_walk(git_revpool *pool); git_commit *gitrp_next(git_revpool *pool); Parsed commits' parents are now also parsed and stored in a "git_commit_list" structure (linked list).

Vicent Marti 417f0abc 2010-05-14T18:44:49 Add basic functionality for commit lookup/parsing The external API function "git_commit_parse" has been renamed to "git_commit_lookup" and has been partially implemented with support for loading commits straight from the ODB. It still lacks the functionality to lookup cached commits in the revpool and to resolve tags to commits. The following internal functions have been partially implemented: int git_commit__parse_buffer(...); int git_commit__parse_time(...); int git_commit__parse_oid(...); Commits are now fully parsed but the generated parent and tree references are not handled yet.

Ramsay Jones e2337f39 2010-04-25T21:55:41 MSVC: Fix a syntax error caused by an inline function definition Commit 5dddf7c (Add block-sha1 in favour of the mozilla routines 2010-04-14) introduced the "bswap.h" header file which contains an inline function (default_swab32()). The msvc compiler does not support the inline keyword which causes the build to fail with a syntax error. However, msvc does support inline functions using the __inline keyword language extension. We already have the GIT_INLINE() macro that allows us to hide this syntatic difference. In order to fix the build, we simply use GIT_INLINE() in the definition of the default_swab32() function.

Andreas Ericsson 5dddf7c8 2010-04-14T20:41:57 Add block-sha1 in favour of the mozilla routines Since block-sha1 from git.git has such excellent performance, we can also get rid of the openssl dependency. It's rather simple to add it back later as an optional extra, but we really needn't bother to pull in the entire ssl library and have to deal with linking issues now that we have the portable and, performance-wise, truly excellent block-sha1 code to fall back on. Since this requires a slight revamp of the build rules anyway, we take the opportunity to fix including EXTRA_OBJS in the final build as well. The block-sha1 code was originally implemented for git.git by Linus Torvalds <torvalds@linux-foundation.org> and was later polished by Nicolas Pitre <nico@cam.org>.

Ramsay Jones 2cdc4544 2010-02-26T22:53:10 Add a pack index 'virtual function' to fetch an index entry Given an index entry number, the idx_get() function returns an (version agnostic) index_entry structure containing all of the information required to unpack the corresponding object from the '.pack' file. Since the v1 and v2 file formats differ in the layout of the object records, we provide two implementations of the get function and initialise the function pointer appropriately.

Ramsay Jones 608d33fa 2010-02-26T19:59:06 Add a pack index 'virtual function' to search by file offset In addition to searching the index by oid, we need to search by '.pack' file offset, particularly when processing OBJ_OFS_DELTA objects. Since the v1 and v2 file formats differ in the layout of the object records, we provide two implementations of the search function and initialise the (virtual) function pointer appropriately. Note that, as part of the creation of the 'offset index', we also add a check that the offset data in the index is within the bounds of the '.pack' file. Having sorted the file offsets, while creating the index, we only need to check the smallest and largest values. The offset index consists of the im_off_idx array, which contains the index entry numbers sorted into file offset order, and the im_off_next mapping array. The im_off_next array maps an index entry number to the 'next' index entry in file offset order. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk>

Ramsay Jones 04e88240 2009-06-17T22:21:10 win32: Define the ssize_t type using SSIZE_T if supported Some win32 compilers define the SSIZE_T type, with the same meaning and intent as ssize_t. If available, make ssize_t a synonym of SSIZE_T. At present, the Digital-Mars compiler is known not to define SSIZE_T, so we provide an SSIZE_T macro to use in the typedef.

Ramsay Jones 5cae6c25 2009-06-17T15:54:59 Disable some msvc "deprecated function" warnings again In addition to removing the inline #define, commit 209849a also removed a #pragma to disable msvc deprecated function warnings. Without this #pragma, msvc currently issues 19 warnings related to "deprecated insecure c-library functions", such as strcpy() and 22 warnings related to "deprecated POSIX function names", such as open(). In order to supress these warnings, re-instate the #pragma. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk>

Ramsay Jones c79dded3 2009-06-14T22:13:35 win32: Add an fsync() implementation for windows For information on FlushFileBuffers(), see the msdn document at msdn.microsoft.com/en-us/library/aa364439(VS.85).aspx Note that Windows 2000 is shown as the minimum windows version to support FlushFileBuffers(), so if we wish to support Win9X and NT4, we will need to add code to dynamically check if kernel32.dll contains the function. The only error return mentioned in the msdn document is ERROR_INVALID_HANDLE, which is returned if the file/device (eg console) is not buffered. The fsync(2) manpage says that EINVAL is returned in errno, if "fd is bound to a special file which does not support synchronization". Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk>

Ramsay Jones 2bf93fa1 2009-06-14T22:10:23 Correct the spelling of the FLEX_ARRAY macro When setting the default value, the macro name was specified as GIT_FLEX_ARRAY, which is inconsistent with it's earlier usage in the file. This caused a compilation error, using the MS Visual C/C++ compiler, when compiling the git_packlist struct definition in src/odb.c. In addition to changing the spelling of the FLEX_ARRAY macro to GIT_FLEX_ARRAY, including it's use in src/odb.c, we also rename the TYPEOF macro to GIT_TYPEOF.

Ramsay Jones 3e0fb8fb 2009-06-04T17:12:59 thread-utils.h: Avoid using a non-standard C construct In particular, in standard C, a struct or union must have at least one member declared (ie. structs and unions cannot be empty). Some compilers allow empty structs as an extension and won't even issue a warning unless asked for it (eg, gcc requires -pedantic). Some compilers allow empty structs as an extension and will only treat it as an error if asked for strict checking (eg Digital-Mars with -A).

Ramsay Jones ac04bdf6 2009-06-04T16:44:54 Fix a usage error in a call to the object_file_name() function In 82324ac, the new static function exists_loose() called object_file_name() and, in order to detect an error return, tested for a negative value. This usage is incorrect, as the error return is indicated by a positive return value. (A successful call is indicated by a zero return value) The only error return from object_file_name() relates to insufficient buffer space and the return value gives the required minimum buffer size (which will always be >0). If the caller requires a dynamically allocated buffer, this allows something like the following call sequence: size_t len = object_file_name(NULL, 0, db->object_dir, id); char *buf = git__malloc(len); if (!buf) error(...); object_file_name(buf, len, db->object_dir,id); ... No current callers take advantage of this capability. Fix up the call site and change the return type of the function, from int to size_t, which more accurately reflects the implementation.
