c8e02b87	2015-02-15T21:07:05	Remove extra semicolon outside of a function Without this change, compiling with gcc and pedantic generates warning: ISO C does not allow extra ‘;’ outside of a function.
f1453c59	2015-02-12T12:19:37	Make our overflow check look more like gcc/clang's Make our overflow checking look more like gcc and clang's, so that we can substitute it out with the compiler instrinsics on platforms that support it. This means dropping the ability to pass `NULL` as an out parameter. As a result, the macros also get updated to reflect this as well.
2884cc42	2015-02-11T09:39:38	overflow checking: don't make callers set oom Have the ALLOC_OVERFLOW testing macros also simply set_oom in the case where a computation would overflow, so that callers don't need to.
392702ee	2015-02-09T23:41:13	allocations: test for overflow of requested size Introduce some helper macros to test integer overflow from arithmetic and set error message appropriately.
208a2c8a	2014-12-27T12:09:11	treebuilder: rename _create() to _new() This function is a constructor, so let's name it like one and leave _create() for the reference functions, which do create/write the reference.
dce7b1a4	2014-12-16T19:24:04	treebuilder: take a repository for path validation Path validation may be influenced by `core.protectHFS` and `core.protectNTFS` configuration settings, thus treebuilders can take a repository to influence their configuration.

7465e873	2014-09-29T09:07:41	index: fill the tree cache on write-tree An obvious place to fill the tree cache is on write-tree, as we're guaranteed to be able to fill in the whole tree cache. The way this commit does this is not the most efficient, as we read the root tree from the odb instead of filling in the cache as we go along, but it fills the cache such that successive operations (and persisting the index to disk) will be able to take advantage of the cache, and it reuses the code we already have for filling the cache. Filling in the cache as we create the trees would require some reallocation of the children vector, which is currently not possible with out pool implementation. A different data structure would likely allow us to perform this operation at a later date.
c2f8b215	2014-09-28T07:00:49	index: write out the tree cache extension Keeping the cache around after read-tree is only one part of the optimisation opportunities. In order to share the cache between program instances, we need to write the TREE extension to the index. Do so, taking the opportunity to rename 'entries' to 'entry_count' to match the name given in the format description. The included test is rather trivial, but works as a sanity check.
966fb207	2014-06-25T21:25:44	tree: free in error conditions As reported by coverity, we would leak some memory in error conditions.
fcc60066	2014-06-09T22:59:32	treentry: no need for manual size book-keeping We can simply ask the hasmap.
978fbb4c	2014-06-09T22:45:23	treebuilder: don't keep removed entries around If the user wants to keep a copy for themselves, they should make a copy. It adds unnecessary complexity to make sure the returned entries are valid until the builder is cleared.
4d3f1f97	2014-06-09T04:38:22	treebuilder: use a map instead of vector to store the entries Finding a filename in a vector means we need to resort it every time we want to read from it, which includes every time we want to write to it as well, as we want to find duplicate keys. A hash-map fits what we want to do much more accurately, as we do not care about sorting, but just the particular filename. We still keep removed entries around, as the interface let you assume they were going to be around until the treebuilder is cleared or freed, but in this case that involves an append to a vector in the filter case, which can now fail. The only time we care about sorting is when we write out the tree, so let's make that the only time we do any sorting.
2c11d2ee	2014-06-09T23:23:53	treebuilder: insert sorted By inserting in the right position, we can keep the vector sorted, making entry insertion almost twice as fast.
882c7742	2014-02-04T10:01:37	Convert pqueue to just be a git_vector This updates the git_pqueue to simply be a set of specialized init/insert/pop functions on a git_vector. To preserve the pqueue feature of having a fixed size heap, I converted the "sorted" field in git_vectors to a more general "flags" field so that pqueue could mix in it's own flag. This had a bunch of ramifications because a number of places were directly looking at the vector "sorted" field - I added a couple new git_vector helpers (is_sorted, set_sorted) so the specific representation of this information could be abstracted.
f000ee4e	2014-01-24T18:23:46	tree: remove legacy 'oid' naming Rename git_tree_entry_byoid() to _byid() as per the convention.
d541170c	2014-01-24T11:36:41	index: rename an entry's id to 'id' This was not converted when we converted the rest, so do it now.
529f342a	2014-01-14T21:33:59	Align git_tree_entry_dup.
26c1cb91	2013-12-09T09:44:03	One more rename/cleanup for callback err functions
25e0b157	2013-12-06T15:07:57	Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
dab89f9b	2013-12-04T21:22:57	Further EUSER and error propagation fixes This continues auditing all the places where GIT_EUSER is being returned and making sure to clear any existing error using the new giterr_user_cancel helper. As a result, places that relied on intercepting GIT_EUSER but having the old error preserved also needed to be cleaned up to correctly stash and then retrieve the actual error. Additionally, as I encountered places where error codes were not being propagated correctly, I tried to fix them up. A number of those fixes are included in the this commit as well.
13f670a5	2013-04-15T09:07:57	tree: allow retrieval of raw attributes When a tool needs to recreate the tree object (for example an interface to another VCS), it needs to use the raw attributes, forgoing any normalization.
d7fc2eb2	2013-09-13T21:36:39	Fix memory leak in git_tree_walk on error or when stopping the walk from the supplied callback
4e01e302	2013-09-13T21:21:33	Prevent git_tree_walk 'skip entry' callback return code from leaking through as the return value of git_tree_walk
a7fcc44d	2013-09-05T16:14:32	Better macro name for is-exec-bit-set test
f240acce	2013-09-05T11:20:12	Add more file mode permissions macros This adds some more macros for some standard operations on file modes, particularly related to permissions, and then updates a number of places around the code base to use the new macros.
114f5a6c	2013-06-10T10:10:39	Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.
58206c9a	2013-05-16T10:38:27	Add cat-file example and increase const use in API This adds an example implementation that emulates git cat-file. It is a convenient and relatively simple example of getting data out of a repository. Implementing this also revealed that there are a number of APIs that are still not using const pointers to objects that really ought to be. The main cause of this is that `git_vector_bsearch` may need to call `git_vector_sort` before doing the search, so a const pointer to the vector is not allowed. However, for tree objects, with a little care, we can ensure that the vector of tree entries is always sorted and allow lookups to take a const pointer. Also, the missing const in commit objects just looks like an oversight.
b60d95c7	2013-05-01T15:55:54	clarify error propogation
0b726701	2013-04-30T13:13:38	object: Explicitly define helper API methods for all obj types
203d5b0e	2013-04-29T18:20:58	Some cleanups Removed useless prototype and renamed object typecast functions declaration macro.
d7761102	2013-04-29T14:22:06	Standardize cast versions of git_object accessors This removes the GIT_INLINE versions of the simple git_object accessors and standardizes them with a helper macro in src/object.h to build the function bodies.
116bbdf0	2013-04-16T12:08:21	clean up tree pointer casting
3f27127d	2013-04-16T11:51:02	Simplify object table parse functions This unifies the object parse functions into one signature that takes an odb_object.
78606263	2013-04-15T00:05:44	Add callback to git_objects_table This adds create and free callback to the git_objects_table so that more of the creation and destruction of objects can be table driven instead of using switch statements. This also makes the semantics of certain object creation functions consistent so that we can make better use of function pointers. This also fixes a theoretical error case where an object allocation fails and we end up storing NULL into the cache.
badd85a6	2013-04-10T17:10:17	Use git_odb_object_data/_size whereever possible This uses the odb object accessors so we can change the internals more easily...

f90391ea	2013-04-18T14:47:54	treebuilder: don't overwrite the error message
0c468633	2013-03-14T13:40:15	Improved tree iterator internals This updates the tree iterator internals to be more efficient. The tree_iterator_entry objects are now kept as pointers that are allocated from a git_pool, so that we may use git__tsort_r for sorting (which is better than qsort, given that the tree is likely mostly ordered already). Those tree_iterator_entry objects now keep direct pointers to the data they refer to instead of keeping indirect index values. This simplifies a lot of the data structure traversal code. This also adds bsearch to find the start item position for range- limited tree iterators, and is more explicit about using git_path_cmp instead of reimplementing it. The git_path_cmp changed a bit to make it easier for tree_iterators to use it (but it was barely being used previously, so not a big deal). This adds a git_pool_free_array function that efficiently frees a list of pool allocated pointers (which the tree_iterator keeps). Also, added new tests for the git_pool free list functionality that was not previously being tested (or used).

e2237179	2013-02-20T10:58:56	Some code cleanups in tree.c This replaces most of the explicit vector iteration with calls to git_vector_foreach, adds in some git__free and giterr_clear calls to clean up during some error paths, and a couple of other code simplifications.
93ab370b	2013-02-20T10:50:01	Store treebuilder length separately from entries vec The treebuilder entries vector flags removed items which means we can't rely on the entries vector length to accurately get the number of entries. This adds an entrycount value and maintains it while updating the treebuilder entries.

98527b5b	2013-01-09T16:03:35	Add git_tree_entry_cmp and git_tree_entry_icmp This adds a new external API git_tree_entry_cmp and a new internal API git_tree_entry_icmp for sorting tree entries. The case insensitive one is internal only because general users should never be seeing case-insensitively sorted trees.

91e7d263	2012-12-10T15:29:44	Fix iterator reset and add reset ranges The `git_iterator_reset` command has not been working in all cases particularly when there is a start and end range. This fixes it and adds tests for it, and also extends it with the ability to update the start/end range strings when an iterator is reset.
9950d27a	2012-12-06T13:26:58	Clean up iterator APIs This removes the need to explicitly pass the repo into iterators where the repo is implied by the other parameters. This moves the repo to be owned by the parent struct. Also, this has some iterator related updates to the internal diff API to lay the groundwork for checkout improvements.
f1c75b94	2012-12-07T15:16:41	tree: relax the filemode parser There are many different broken filemodes in the wild so we need to protect against them and give something useful up the chain. Don't fail when reading a tree from the ODB but normalize the mode as best we can. As 664 is no longer a mode that we consider to be valid and gets normalized to 644, we can stop accepting it in the treebuilder. The library won't expose it to the user, so any invalid modes are a bug.

16248ee2	2012-11-21T11:03:07	Fix up some missing consts in tree & index This fixes some missed places where we can apply const-ness to various public APIs. There are still some index and tree APIs that cannot take const pointers because we sort our `git_vectors` lazily and so we can't reliably bsearch the index and tree content without applying a `git_vector_sort()` first. This also fixes some missed places where size_t can be used and where const can be applied to a couple internal functions.

cfeef7ce	2012-11-19T13:40:08	Minor optimization to tree entry validity check This checks for a leading '.' before looking for the invalid tree entry names. Even on pretty high levels of optimization, this seems to make a measurable improvement. I accidentally used && in the check initially instead of \|\| and while debugging ended up improving the error reporting of issues with adding tree entries. I thought I'd leave those changes, too.

0d64bef9	2012-10-05T15:56:57	Add complex checkout test and then fix checkout This started as a complex new test for checkout going through the "typechanges" test repository, but that revealed numerous issues with checkout, including: * complete failure with submodules * failure to create blobs with exec bits * problems when replacing a tree with a blob because the tree "example/" sorts after the blob "example" so the delete was being processed after the single file blob was created This fixes most of those problems and includes a number of other minor changes that made it easier to do that, including improving the TYPECHANGE support in diff/status, etc.

a6bf1687	2012-08-13T14:07:47	tree: allow the user to skip an entry or cancel the walk Returning a negative cancels the walk, and returning a positive one causes us to skip an entry, which was previously done by a negative value. This allows us to stay consistent with the rest of the functions that take a callback and keeps the skipping functionality.
53ae1235	2012-08-13T14:00:53	tree: bring back the documented behaviour for a walk However, there should be a way to cancel the walk and another to skip the entry.

b0d37669	2012-08-03T17:24:59	Add new iteration behavior to git_tree_walk Missed this one, ironically enough.
2031760c	2012-07-26T16:10:22	Fix git_tree_walk to return user error This makes sure that an error code returned by the callback function of `git_tree_walk` will stop the iteration and get propagated back to the caller verbatim. Also, this adds a minor helper function `git_tree_entry_byoid` that searches a `git_tree` for an entry with the given OID. This isn't a fast function, but it's easier than writing the loop yourself as an external user of the library.

41a82592	2012-05-15T14:17:39	Ranged iterators and rewritten git_status_file The goal of this work is to rewrite git_status_file to use the same underlying code as git_status_foreach. This is done in 3 phases: 1. Extend iterators to allow ranged iteration with start and end prefixes for the range of file names to be covered. 2. Improve diff so that when there is a pathspec and there is a common non-wildcard prefix of the pathspec, it will use ranged iterators to minimize excess iteration. 3. Rewrite git_status_file to call git_status_foreach_ext with a pathspec that covers just the one file being checked. Since ranged iterators underlie the status & diff implementation, this is actually fairly efficient. The workdir iterator does end up loading the contents of all the directories down to the single file, which should ideally be avoided, but it is pretty good.

1744fafe	2012-01-17T15:49:47	Move path related functions from fileops to path This takes all of the functions that look up simple data about paths (such as `git_futils_isdir`) and moves them over to path.h (becoming `git_path_isdir`). This leaves fileops.h just with functions that actually manipulate the filesystem or look at the file contents in some way. As part of this, the dir.h header which is really just for win32 support was moved into win32 (with some minor changes).

index: fill the tree cache on write-tree An obvious place to fill the tree cache is on write-tree, as we're guaranteed to be able to fill in the whole tree cache. The way this commit does this is not the most efficient, as we read the root tree from the odb instead of filling in the cache as we go along, but it fills the cache such that successive operations (and persisting the index to disk) will be able to take advantage of the cache, and it reuses the code we already have for filling the cache. Filling in the cache as we create the trees would require some reallocation of the children vector, which is currently not possible with out pool implementation. A different data structure would likely allow us to perform this operation at a later date.

index: write out the tree cache extension Keeping the cache around after read-tree is only one part of the optimisation opportunities. In order to share the cache between program instances, we need to write the TREE extension to the index. Do so, taking the opportunity to rename 'entries' to 'entry_count' to match the name given in the format description. The included test is rather trivial, but works as a sanity check.

treebuilder: use a map instead of vector to store the entries Finding a filename in a vector means we need to resort it every time we want to read from it, which includes every time we want to write to it as well, as we want to find duplicate keys. A hash-map fits what we want to do much more accurately, as we do not care about sorting, but just the particular filename. We still keep removed entries around, as the interface let you assume they were going to be around until the treebuilder is cleared or freed, but in this case that involves an append to a vector in the filter case, which can now fail. The only time we care about sorting is when we write out the tree, so let's make that the only time we do any sorting.

Convert pqueue to just be a git_vector This updates the git_pqueue to simply be a set of specialized init/insert/pop functions on a git_vector. To preserve the pqueue feature of having a fixed size heap, I converted the "sorted" field in git_vectors to a more general "flags" field so that pqueue could mix in it's own flag. This had a bunch of ramifications because a number of places were directly looking at the vector "sorted" field - I added a couple new git_vector helpers (is_sorted, set_sorted) so the specific representation of this information could be abstracted.

One more rename/cleanup for callback err functions

25e0b157

2013-12-06T15:07:57

Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.

Further EUSER and error propagation fixes This continues auditing all the places where GIT_EUSER is being returned and making sure to clear any existing error using the new giterr_user_cancel helper. As a result, places that relied on intercepting GIT_EUSER but having the old error preserved also needed to be cleaned up to correctly stash and then retrieve the actual error. Additionally, as I encountered places where error codes were not being propagated correctly, I tried to fix them up. A number of those fixes are included in the this commit as well.

Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.

Add cat-file example and increase const use in API This adds an example implementation that emulates git cat-file. It is a convenient and relatively simple example of getting data out of a repository. Implementing this also revealed that there are a number of APIs that are still not using const pointers to objects that really ought to be. The main cause of this is that `git_vector_bsearch` may need to call `git_vector_sort` before doing the search, so a const pointer to the vector is not allowed. However, for tree objects, with a little care, we can ensure that the vector of tree entries is always sorted and allow lookups to take a const pointer. Also, the missing const in commit objects just looks like an oversight.

Improved tree iterator internals This updates the tree iterator internals to be more efficient. The tree_iterator_entry objects are now kept as pointers that are allocated from a git_pool, so that we may use git__tsort_r for sorting (which is better than qsort, given that the tree is likely mostly ordered already). Those tree_iterator_entry objects now keep direct pointers to the data they refer to instead of keeping indirect index values. This simplifies a lot of the data structure traversal code. This also adds bsearch to find the start item position for range- limited tree iterators, and is more explicit about using git_path_cmp instead of reimplementing it. The git_path_cmp changed a bit to make it easier for tree_iterators to use it (but it was barely being used previously, so not a big deal). This adds a git_pool_free_array function that efficiently frees a list of pool allocated pointers (which the tree_iterator keeps). Also, added new tests for the git_pool free list functionality that was not previously being tested (or used).

tree: relax the filemode parser There are many different broken filemodes in the wild so we need to protect against them and give something useful up the chain. Don't fail when reading a tree from the ODB but normalize the mode as best we can. As 664 is no longer a mode that we consider to be valid and gets normalized to 644, we can stop accepting it in the treebuilder. The library won't expose it to the user, so any invalid modes are a bug.

This also fixes some missed places where size_t can be used and where const can be applied to a couple internal functions.

Minor optimization to tree entry validity check This checks for a leading '.' before looking for the invalid tree entry names.

Ranged iterators and rewritten git_status_file The goal of this work is to rewrite git_status_file to use the same underlying code as git_status_foreach. This is done in 3 phases: 1. Extend iterators to allow ranged iteration with start and end prefixes for the range of file names to be covered. 2. Improve diff so that when there is a pathspec and there is a common non-wildcard prefix of the pathspec, it will use ranged iterators to minimize excess iteration. 3. Rewrite git_status_file to call git_status_foreach_ext with a pathspec that covers just the one file being checked. Since ranged iterators underlie the status & diff implementation, this is actually fairly efficient. The workdir iterator does end up loading the contents of all the directories down to the single file, which should ideally be avoided, but it is pretty good.

Move path related functions from fileops to path This takes all of the functions that look up simple data about paths (such as `git_futils_isdir`) and moves them over to path.h (becoming `git_path_isdir`). This leaves fileops.h just with functions that actually manipulate the filesystem or look at the file contents in some way. As part of this, the dir.h header which is really just for win32 support was moved into win32 (with some minor changes).
