83e8a6b3	2018-10-18T16:08:46	util: provide `git__memmem` function Unfortunately, neither the `memmem` nor the `strnstr` functions are part of any C standard but are merely extensions of C that are implemented by e.g. glibc. Thus, there is no standardized way to search for a string in a block of memory with a limited size, and using `strstr` is to be considered unsafe in case where the buffer has not been sanitized. In fact, there are some uses of `strstr` in exactly that unsafe way in our codebase. Provide a new function `git__memmem` that implements the `memmem` semantics. That is in a given haystack of `n` bytes, search for the occurrence of a byte sequence of `m` bytes and return a pointer to the first occurrence. The implementation chosen is the "Not So Naive" algorithm from [1]. It was chosen as the implementation is comparably simple while still being reasonably efficient in most cases. Preprocessing happens in constant time and space, searching has a time complexity of O(n*m) with a slightly sub-linear average case. [1]: http://www-igm.univ-mlv.fr/~lecroq/string/
8d7fa88a	2018-10-18T12:04:07	util: remove `git__strtol32` The function `git__strtol32` can easily be misused when untrusted data is passed to it that may not have been sanitized with trailing `NUL` bytes. As all usages of this function have now been removed, we can remove this function altogether to avoid future misuse of it.
68deb2cc	2018-10-18T11:37:10	util: remove unsafe `git__strtol64` function The function `git__strtol64` does not take a maximum buffer length as parameter. This has led to some unsafe usages of this function, and as such we may consider it as being unsafe to use. As we have now eradicated all usages of this function, let's remove it completely to avoid future misuse.
d2e996fa	2018-03-14T10:36:14	util: extract allocators into its own "alloc.h" header Our "util.h" header is a grabbag of various different functions, where many don't have a clear group they belong to. Our set of allocator functions though can be clearly singled out as a single group of functions that always belongs together. Furthermore, we will need to implement additional functions relating to our allocators subsystem when moving to pluggable allocators. Thus, we should just move these functions into their own "alloc" module.
c47f7155	2018-03-14T10:34:59	util: extract `stdalloc` allocator into its own module Right now, the standard allocator is being declared as part of the "util.h" header as a set of inline functions. As with the crtdbg allocator functions, these inline functions make it hard to convert to function pointers for our allocators. Create a new "stdalloc" module containing our standard allocations functions to split these out. Convert the existing allocators to macros which make use of the stdalloc functions.
496b0df2	2018-03-14T10:28:50	win32: crtdbg: provide independent `free` function Currently, the `git__free` function is being defined in a single place, only, disregarding whether we use our standard allocators or the crtdbg allocators. This makes it a bit harder to convert our code base to use pluggable allocators, and furthermore makes the border between our two allocators a bit more blurry. Implement a separate `git__crtdbg__free` function for the crtdbg allocator in order to completely separate both allocator implementations.
9d83a2b0	2018-02-22T22:55:50	Sanitize the hunk header to ensure it contains UTF-8 valid data The diff driver truncates the hunk header text to 80 bytes, which can truncate 4-byte Unicode characters and introduce garbage characters in the diff output. This change sanitizes the hunk header before it is displayed. This mirrors the test in git: https://github.com/git/git/blob/master/t/t4025-hunk-header.sh Closes https://github.com/libgit2/rugged/issues/716
92324d84	2018-02-16T11:28:53	util: clean up header includes While "util.h" declares the macro `git__tolower`, which simply resorts to tolower(3P) on Unix-like systems, the <ctype.h> header is only being included in "util.c". Thus, anybody who has included "util.h" without having <ctype.h> included will fail to compile as soon as the macro is in use. Furthermore, we can clean up additional includes in "util.c" and simply replace them with an include for "common.h".

86219f40	2017-11-30T15:40:13	util: introduce `git__prefixncmp` and consolidate implementations Introduce `git_prefixncmp` that will search up to the first `n` characters of a string to see if it is prefixed by another string. This is useful for examining if a non-null terminated character array is prefixed by a particular substring. Consolidate the various implementations of `git__prefixcmp` around a single core implementation and add some test cases to validate its behavior.
585b5dac	2017-11-18T15:43:11	refcount: make refcounting conform to aliasing rules Strict aliasing rules dictate that for most data types, you are not allowed to cast them to another data type and then access the casted pointers. While this works just fine for most compilers, technically we end up in undefined behaviour when we hurt that rule. Our current refcounting code makes heavy use of casting and thus violates that rule. While we didn't have any problems with that code, Travis started spitting out a lot of warnings due to a change in their toolchain. In the refcounting case, the code is also easy to fix: as all refcounting-statements are actually macros, we can just access the `rc` field directly instead of casting. There are two outliers in our code where that doesn't work. Both the `git_diff` and `git_patch` structures have specializations for generated and parsed diffs/patches, which directly inherit from them. Because of that, the refcounting code is only part of the base structure and not of the children themselves. We can help that by instead passing their base into `GIT_REFCOUNT_INC`, though.
0c7f49dd	2017-06-30T13:39:01	Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.
0fb4b351	2017-06-30T13:27:26	Fix missing include for header files Some of our header files are not included at all by any of their implementing counter-parts. Including them inside of these files leads to some compile errors mostly due to unknown types because of missing includes. But there's also one case where a declared function does not match the implementation's prototype. Fix all these errors by fixing up the prototype and adding missing includes. This is preparatory work for fixing up missing includes in the implementation files.
459fb8fe	2017-06-30T15:35:46	win32: fix circular include deps with w32_crtdbg The current order of declarations and includes between "common.h" and "w32_crtdbg_stacktrace.h" is rather complicated. Both header files make use of things defined in the other one and are thus circularly dependent on each other. This makes it currently impossible to compile the "w32_crtdbg_stacktrace.c" file when including "common.h" inside of "w32_crtdbg_stacktrace.h". We can disentangle the mess by moving declaration of the inline crtdbg functions into the "w32_crtdbg_stacktrace.h" file and adding additional includes inside of it, such that all required functions are available to it. This allows us to break the dependency cycle.

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.

fe5f7722	2014-12-23T11:27:01	don't treat 0x85 as whitespace A byte value of 0x85 is not whitespace, we were conflating that with U+0085 (UTF8: 0xc2 0x85). This caused us to incorrectly treat valid multibyte characters like U+88C5 (UTF8: 0xe8 0xa3 0x85) as whitespace.

a64119e3	2014-11-25T18:13:00	checkout: disallow bad paths on win32 Disallow: 1. paths with trailing dot 2. paths with trailing space 3. paths with trailing colon 4. paths that are 8.3 short names of .git folders ("GIT~1") 5. paths that are reserved path names (COM1, LPT1, etc). 6. paths with reserved DOS characters (colons, asterisks, etc) These paths would (without \\?\ syntax) be elided to other paths - for example, ".git." would be written as ".git". As a result, writing these paths literally (using \\?\ syntax) makes them hard to operate with from the shell, Windows Explorer or other tools. Disallow these.

To take advantage of this, I had to export a number of the internal index entry comparison functions. I also wrote some new tests to exercise the capability.

Split the definition on p_strlen() off into its own header so we can use it in util.h.

b176eded	2013-09-19T14:52:57	Initial Implementation of progress reports during push This adds the basics of progress reporting during push. While progress for all aspects of a push operation are not reported with this change, it lays the foundation to add these later. Push progress reporting can be improved in the future - and consumers of the API should just get more accurate information at that point. The main areas where this is lacking are: 1) packbuilding progress: does not report progress during deltafication, as this involves coordinating progress from multiple threads. 2) network progress: reports progress as objects and bytes are going to be written to the subtransport (instead of as client gets confirmation that they have been received by the server) and leaves out some of the bytes that are transfered as part of the push protocol. Basically, this reports the pack bytes that are written to the subtransport. It does not report the bytes sent on the wire that are received by the server. This should be a good estimate of progress (and an improvement over no progress).

d730d3f4	2013-07-31T16:40:42	Major rename detection changes After doing further profiling, I found that a lot of time was being spent attempting to insert hashes into the file hash signature when using the rolling hash because the rolling hash approach generates a hash per byte of the file instead of one per run/line of data. To optimize this, I decided to convert back to a run-based file signature algorithm which would be more like core Git. After changing this, a number of the existing tests started to fail. In some cases, this appears to have been because the test was coded to be too specific to the particular results of the file similarity metric and in some cases there appear to have been bugs in the core rename detection code where only by the coincidence of the file similarity scoring were the expected results being generated. This renames all the variables in the core rename detection code to be more consistent and hopefully easier to follow which made it a bit easier to reason about the behavior of that code and fix the problems that I was seeing. I think it's in better shape now. There are a couple of tests now that attempt to stress test the rename detection code and they are quite slow. Most of the time is spent setting up the test data on disk and in the index. When we roll out performance improvements for index insertion, it should also speed up these tests I hope.

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.
3e9e6cda	2013-06-07T09:54:33	Add safe memset and use it This adds a `git__memset` routine that will not be optimized away and updates the places where I memset() right before a free() call to use it.
d958e37a	2013-05-17T17:21:45	Fix issues with git_diff_find_similar There are a number of bugs in the rename code that only were obvious when I started testing it against large old repos with more complex patterns. (The code to do that testing is not ready to merge with libgit2, but I do plan to add more thorough tests.) This contains a significant number of changes and also tweaks the public API slightly to make emulating core git easier. Most notably, this separates the GIT_DIFF_FIND_AND_BREAK_REWRITES flag into FIND_REWRITES (which adds a self-similarity score to every modified file) and BREAK_REWRITES (which splits the modified deltas into add/remove pairs in the diff list). When you do a raw output of core git, rewrites show up as M090 or such, not at A and D output, so I wanted to be able to emulate that. Publicly, this also changes the flags to be uint16_t since we don't need values out of that range. Internally, this contains significant changes from a number of small bug fixes (like using the wrong side of the diff to decide if the object could be found in the ODB vs the workdir) to larger issues about which files can and should be compared and how the various edge cases of similarity scores should be treated. Honestly, I don't think this is the last update that will have to be made to this code, but I think this moves us closer to correct behavior and I tried to document the code so it would be easier to follow..

e976b56d	2013-04-15T14:27:53	Add git__compare_and_swap and use it This removes the lock from the repository object and changes the internals to use the new atomic git__compare_and_swap to update the _odb, _config, _index, and _refdb variables in a threadsafe manner.
53607868	2013-04-15T00:09:03	Further threading fixes This builds on the earlier thread safety work to make it so that setting the odb, index, refdb, or config for a repository is done in a threadsafe manner with minimized locking time. This is done by adding a lock to the repository object and using it to guard the assignment of the above listed pointers. The lock is only held to assign the pointer value. This also contains some minor fixes to the other work with pack files to reduce the time that locks are being held to and fix an apparently memory leak.
4dcd8780	2013-04-19T17:17:44	Move refdb_backend to include/git2/sys This moves most of the refdb stuff over to the include/git2/sys directory, with some minor shifts in function organization. While I was making the necessary updates, I also removed the trailing whitespace in a few files that I modified just because I was there and it was bugging me.
62beacd3	2013-03-11T16:43:58	Sorting function cleanup and MinGW fix Clean up some sorting function stuff including fixing qsort_r on MinGW, common function pointer type for comparison, and basic insertion sort implementation (which we, regrettably, fall back on for MinGW).
e40f1c2d	2013-03-08T16:39:57	Make tree iterator handle icase equivalence There is a serious bug in the previous tree iterator implementation. If case insensitivity resulted in member elements being equivalent to one another, and those member elements were trees, then the children of the colliding elements would be processed in sequence instead of in a single flattened list. This meant that the tree iterator was not truly acting like a case-insensitive list. This completely reworks the tree iterator to manage lists with case insensitive equivalence classes and advance through the items in a unified manner in a single sorted frame. It is possible that at a future date we might want to update this to separate the case insensitive and case sensitive tree iterators so that the case sensitive one could be a minimal amount of code and the insensitive one would always know what it needed to do without checking flags. But there would be so much shared code between the two, that I'm not sure it that's a win. For now, this gets what we need. More tests are needed, though.

55cbd05b	2012-11-08T16:56:34	Some diff refactorings to help code reuse There are some diff functions that are useful in a rewritten checkout and this lays some groundwork for that. This contains three main things: 1. Share the function diff uses to calculate the OID for a file in the working directory (now named `git_diff__oid_for_file` 2. Add a `git_diff__paired_foreach` function to iterator over two diff lists concurrently. Convert status to use it. 3. Move all the string/prefix/index entry comparisons into function pointers inside the `git_diff_list` object so they can be switched between case sensitive and insensitive versions. This makes them easier to reuse in various functions without replicating logic. As part of this, move a couple of index functions out of diff.c and into index.c.

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.

Fixed this by pre-joining the relative path of the attribute/ignore file onto the match string when a full path match is required. Unfortunately, fixing this required a bit more code than I would have liked because I had to juggle things around so that the fnmatch parser would have sufficient information to prepend the relative path when it was needed.

Also, this adds a new vector function `git_vector_insert_sorted()` which allows you to maintain a sorted list as you go. In order to write that function, this changes the function `git__bsearch()` to take a somewhat different set of parameters, although the core functionality is still the same.

Additionally, improved the handling of global and system files, making common utility functions in fileops and converting config and attr to both use the common functions. Adds a bunch more tests and fixed some memory leaks. Note that adding macros required me to use refcounted attribute assignment definitions, which complicated, but probably improved memory usage.

util: provide `git__memmem` function Unfortunately, neither the `memmem` nor the `strnstr` functions are part of any C standard but are merely extensions of C that are implemented by e.g. glibc. Thus, there is no standardized way to search for a string in a block of memory with a limited size, and using `strstr` is to be considered unsafe in case where the buffer has not been sanitized. In fact, there are some uses of `strstr` in exactly that unsafe way in our codebase. Provide a new function `git__memmem` that implements the `memmem` semantics. That is in a given haystack of `n` bytes, search for the occurrence of a byte sequence of `m` bytes and return a pointer to the first occurrence. The implementation chosen is the "Not So Naive" algorithm from [1]. It was chosen as the implementation is comparably simple while still being reasonably efficient in most cases. Preprocessing happens in constant time and space, searching has a time complexity of O(n*m) with a slightly sub-linear average case. [1]: http://www-igm.univ-mlv.fr/~lecroq/string/

util: extract allocators into its own "alloc.h" header Our "util.h" header is a grabbag of various different functions, where many don't have a clear group they belong to. Our set of allocator functions though can be clearly singled out as a single group of functions that always belongs together. Furthermore, we will need to implement additional functions relating to our allocators subsystem when moving to pluggable allocators. Thus, we should just move these functions into their own "alloc" module.

util: extract `stdalloc` allocator into its own module Right now, the standard allocator is being declared as part of the "util.h" header as a set of inline functions. As with the crtdbg allocator functions, these inline functions make it hard to convert to function pointers for our allocators. Create a new "stdalloc" module containing our standard allocations functions to split these out. Convert the existing allocators to macros which make use of the stdalloc functions.

win32: crtdbg: provide independent `free` function Currently, the `git__free` function is being defined in a single place, only, disregarding whether we use our standard allocators or the crtdbg allocators. This makes it a bit harder to convert our code base to use pluggable allocators, and furthermore makes the border between our two allocators a bit more blurry. Implement a separate `git__crtdbg__free` function for the crtdbg allocator in order to completely separate both allocator implementations.

Thus, anybody who has included "util.h" without having <ctype.h> included will fail to compile as soon as the macro is in use. Furthermore, we can clean up additional includes in "util.c" and simply replace them with an include for "common.h".

refcount: make refcounting conform to aliasing rules Strict aliasing rules dictate that for most data types, you are not allowed to cast them to another data type and then access the casted pointers. While this works just fine for most compilers, technically we end up in undefined behaviour when we hurt that rule. Our current refcounting code makes heavy use of casting and thus violates that rule. While we didn't have any problems with that code, Travis started spitting out a lot of warnings due to a change in their toolchain. In the refcounting case, the code is also easy to fix: as all refcounting-statements are actually macros, we can just access the `rc` field directly instead of casting. There are two outliers in our code where that doesn't work. Both the `git_diff` and `git_patch` structures have specializations for generated and parsed diffs/patches, which directly inherit from them. Because of that, the refcounting code is only part of the base structure and not of the children themselves. We can help that by instead passing their base into `GIT_REFCOUNT_INC`, though.

Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.

Fix missing include for header files Some of our header files are not included at all by any of their implementing counter-parts. Including them inside of these files leads to some compile errors mostly due to unknown types because of missing includes. But there's also one case where a declared function does not match the implementation's prototype. Fix all these errors by fixing up the prototype and adding missing includes. This is preparatory work for fixing up missing includes in the implementation files.

win32: fix circular include deps with w32_crtdbg The current order of declarations and includes between "common.h" and "w32_crtdbg_stacktrace.h" is rather complicated. Both header files make use of things defined in the other one and are thus circularly dependent on each other. This makes it currently impossible to compile the "w32_crtdbg_stacktrace.c" file when including "common.h" inside of "w32_crtdbg_stacktrace.h". We can disentangle the mess by moving declaration of the inline crtdbg functions into the "w32_crtdbg_stacktrace.h" file and adding additional includes inside of it, such that all required functions are available to it. This allows us to break the dependency cycle.

Initial Implementation of progress reports during push This adds the basics of progress reporting during push. While progress for all aspects of a push operation are not reported with this change, it lays the foundation to add these later. Push progress reporting can be improved in the future - and consumers of the API should just get more accurate information at that point. The main areas where this is lacking are: 1) packbuilding progress: does not report progress during deltafication, as this involves coordinating progress from multiple threads. 2) network progress: reports progress as objects and bytes are going to be written to the subtransport (instead of as client gets confirmation that they have been received by the server) and leaves out some of the bytes that are transfered as part of the push protocol. Basically, this reports the pack bytes that are written to the subtransport. It does not report the bytes sent on the wire that are received by the server. This should be a good estimate of progress (and an improvement over no progress).

Major rename detection changes After doing further profiling, I found that a lot of time was being spent attempting to insert hashes into the file hash signature when using the rolling hash because the rolling hash approach generates a hash per byte of the file instead of one per run/line of data. To optimize this, I decided to convert back to a run-based file signature algorithm which would be more like core Git. After changing this, a number of the existing tests started to fail. In some cases, this appears to have been because the test was coded to be too specific to the particular results of the file similarity metric and in some cases there appear to have been bugs in the core rename detection code where only by the coincidence of the file similarity scoring were the expected results being generated. This renames all the variables in the core rename detection code to be more consistent and hopefully easier to follow which made it a bit easier to reason about the behavior of that code and fix the problems that I was seeing. I think it's in better shape now. There are a couple of tests now that attempt to stress test the rename detection code and they are quite slow. Most of the time is spent setting up the test data on disk and in the index. When we roll out performance improvements for index insertion, it should also speed up these tests I hope.

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.

Fix issues with git_diff_find_similar There are a number of bugs in the rename code that only were obvious when I started testing it against large old repos with more complex patterns. (The code to do that testing is not ready to merge with libgit2, but I do plan to add more thorough tests.) This contains a significant number of changes and also tweaks the public API slightly to make emulating core git easier. Most notably, this separates the GIT_DIFF_FIND_AND_BREAK_REWRITES flag into FIND_REWRITES (which adds a self-similarity score to every modified file) and BREAK_REWRITES (which splits the modified deltas into add/remove pairs in the diff list). When you do a raw output of core git, rewrites show up as M090 or such, not at A and D output, so I wanted to be able to emulate that. Publicly, this also changes the flags to be uint16_t since we don't need values out of that range. Internally, this contains significant changes from a number of small bug fixes (like using the wrong side of the diff to decide if the object could be found in the ODB vs the workdir) to larger issues about which files can and should be compared and how the various edge cases of similarity scores should be treated. Honestly, I don't think this is the last update that will have to be made to this code, but I think this moves us closer to correct behavior and I tried to document the code so it would be easier to follow..

Further threading fixes This builds on the earlier thread safety work to make it so that setting the odb, index, refdb, or config for a repository is done in a threadsafe manner with minimized locking time. This is done by adding a lock to the repository object and using it to guard the assignment of the above listed pointers. The lock is only held to assign the pointer value. This also contains some minor fixes to the other work with pack files to reduce the time that locks are being held to and fix an apparently memory leak.

Make tree iterator handle icase equivalence There is a serious bug in the previous tree iterator implementation. If case insensitivity resulted in member elements being equivalent to one another, and those member elements were trees, then the children of the colliding elements would be processed in sequence instead of in a single flattened list. This meant that the tree iterator was not truly acting like a case-insensitive list. This completely reworks the tree iterator to manage lists with case insensitive equivalence classes and advance through the items in a unified manner in a single sorted frame. It is possible that at a future date we might want to update this to separate the case insensitive and case sensitive tree iterators so that the case sensitive one could be a minimal amount of code and the insensitive one would always know what it needed to do without checking flags. But there would be so much shared code between the two, that I'm not sure it that's a win. For now, this gets what we need. More tests are needed, though.

Add payload "_r" versions of bsearch and tsort git__bsearch and git__tsort did not pass a payload through to the comparison function. This makes it impossible to implement sorted lists where the sort order depends on external data (e.g. building a secondary sort order for the entries in a tree). This commit adds git__bsearch_r and git__tsort_r versions that pass a third parameter to the cmp function of a user payload.

Create internal strcmp variants for function ptrs Using the builtin strcmp and strcasecmp as function pointers is problematic on win32. This adds internal implementations and divorces us from the platform linkage.

Some diff refactorings to help code reuse There are some diff functions that are useful in a rewritten checkout and this lays some groundwork for that. This contains three main things: 1. Share the function diff uses to calculate the OID for a file in the working directory (now named `git_diff__oid_for_file` 2. Add a `git_diff__paired_foreach` function to iterator over two diff lists concurrently. Convert status to use it. 3. Move all the string/prefix/index entry comparisons into function pointers inside the `git_diff_list` object so they can be switched between case sensitive and insensitive versions. This makes them easier to reuse in various functions without replicating logic. As part of this, move a couple of index functions out of diff.c and into index.c.

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.

error-handling: On-disk config file backend Includes: - Proper error reporting when encountering syntax errors in a config file (file, line number, column). - Rewritten `config_write`, now with 99% less goto-spaghetti - Error state in `git_filebuf`: filebuf write functions no longer need to be checked for error returns. If any of the writes performed on a buffer fail, the last call to `git_filebuf_commit` or `git_filebuf_hash` will fail accordingly and set the appropiate error message. Baller!

error-handling: Repository This also includes droping `git_buf_lasterror` because it makes no sense in the new system. Note that in most of the places were it has been dropped, the code needs cleanup. I.e. GIT_ENOMEM is going away, so instead it should return a generic `-1` and obviously not throw anything.

Remove poor git__removechar function Going back over this, the git__removechar function was not needed (only invoked once) and is actually mislabeled. As implemented, it really only made sense for removing backslash characters, since two of the "removed" characters in a row would include the second one -- i.e. it really implements stripping backslash-escaped strings where a backslash allows internal whitespace in a word.

Fix handling of relative paths for attrs Per issue #533, the handling of relative paths in attribute and ignore files was not right. Fixed this by pre-joining the relative path of the attribute/ignore file onto the match string when a full path match is required. Unfortunately, fixing this required a bit more code than I would have liked because I had to juggle things around so that the fnmatch parser would have sufficient information to prepend the relative path when it was needed.

Initial implementation of gitignore support Adds support for .gitignore files to git_status_foreach() and git_status_file(). This includes refactoring the gitattributes code to share logic where possible. The GIT_STATUS_IGNORED flag will now be passed in for files that are ignored (provided they are not already in the index or the head of repo).

Improved gitattributes macro implementation This updates to implementation of gitattribute macros to be much more similar to core git (albeit not 100%) and to handle expansion of macros within macros, etc. It also cleans up the refcounting usage with macros to be much cleaner. Also, this adds a new vector function `git_vector_insert_sorted()` which allows you to maintain a sorted list as you go. In order to write that function, this changes the function `git__bsearch()` to take a somewhat different set of parameters, although the core functionality is still the same.

Add support for macros and cache flush API. Add support for git attribute macro definitions. Also, add support for cache flush API to clear the attribute file content cache when needed. Additionally, improved the handling of global and system files, making common utility functions in fileops and converting config and attr to both use the common functions. Adds a bunch more tests and fixed some memory leaks. Note that adding macros required me to use refcounted attribute assignment definitions, which complicated, but probably improved memory usage.
