libgit2 has two distinct requirements that were previously solved by `git_buf`. We require: 1. A general purpose string class that provides a number of utility APIs for manipulating data (eg, concatenating, truncating, etc). 2. A structure that we can use to return strings to callers that they can take ownership of. By using a single class (`git_buf`) for both of these purposes, we have confused the API to the point that refactorings are difficult and reasoning about correctness is also difficult. Move the utility class `git_buf` to be called `git_str`: this represents its general purpose, as an internal string buffer class. The name also is an homage to Junio Hamano ("gitstr"). The public API remains `git_buf`, and has a much smaller footprint. It is generally only used as an "out" param with strict requirements that follow the documentation. (Exceptions exist for some legacy APIs to avoid breaking callers unnecessarily.) Utility functions exist to convert a user-specified `git_buf` to a `git_str` so that we can call internal functions, then converting it back again.

The information about the type of a revision spec is not information about the parser. Name it accordingly, so that `git_revparse_mode_t` is now `git_revspec_t`. Deprecate the old name.

When queueing objects we want to push, we call `git_revwalk_hide` to hide all objects already known to the remote from our revwalk. We do not check its return value though, where the orginial intent was to ignore the case where the pushed OID is not a known committish. As `git_revwalk_hide` can fail due to other reasons like out-of-memory exceptions, we should still check its return value. Fix the issue by checking the function's return value, ignoring errors hinting that it's not a committish. As `git_revwalk__push_commit` currently clobbers these error codes, we need to adjust it as well in order to make it available downstream.

Before we can tweak the revwalk to be more efficent when negotiating, we need to add an "insertion mode" option. Since there's already an implicit set of those, make it visible, at least privately.

This is not implemented and should fail, but it should also not leak. To allow the memory debugger to find leaks and fix this one we test this.

If someone passes just one ref (i.e. "master") and misses passing the range we should be nice and return an error code instead of crashing.

Currently, one would use either `git_oidmap_insert` to insert key/value pairs into a map or `git_oidmap_put` to insert a key only. These function have historically been macros, which is why their syntax is kind of weird: instead of returning an error code directly, they instead have to be passed a pointer to where the return value shall be stored. This does not match libgit2's common idiom of directly returning error codes.Furthermore, `git_oidmap_put` is tightly coupled with implementation details of the map as it exposes the index of inserted entries. Introduce a new function `git_oidmap_set`, which takes as parameters the map, key and value and directly returns an error code. Convert all trivial callers of `git_oidmap_insert` and `git_oidmap_put` to make use of it.

The current way of looking up an entry from a map is tightly coupled with the map implementation, as one first has to look up the index of the key and then retrieve the associated value by using the index. As a caller, you usually do not care about any indices at all, though, so this is more complicated than really necessary. Furthermore, it invites for errors to happen if the correct error checking sequence is not being followed. Introduce a new high-level function `git_oidmap_get` that takes a map and a key and returns a pointer to the associated value if such a key exists. Otherwise, a `NULL` pointer is returned. Adjust all callers that can trivially be converted.

Currently, the lifecycle functions for maps (allocation, deallocation, resize) are not named in a uniform way and do not have a uniform function signature. Rename the functions to fix that, and stick to libgit2's naming scheme of saying `git_foo_new`. This results in the following new interface for allocation: - `int git_<t>map_new(git_<t>map **out)` to allocate a new map, returning an error code if we ran out of memory - `void git_<t>map_free(git_<t>map *map)` to free a map - `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map This commit also fixes all existing callers.

Instead of using the `khiter_t`, `git_strmap_iter` and `khint_t` types, simply use `size_t` instead. This decouples code from the khash stuff and makes it possible to move the khash includes into the implementation files.

Since git_revwalk objects are encouraged to be reused, a public interface for changing hide_cb is desirable.

This is not a big deal, but it does make us match git more closely by checking only the first. The lists are sorted already, so there should be no functional difference other than removing a possible check from every iteration in the loop.
Carlos Martín Nieto committed -
When porting, we overlooked that the difference between git's and our's time representation and copied their way of getting the max value. Unfortunately git was using unsigned integers, so `~0ll` does correspond to their max value, whereas for us it corresponds to `-1`. This means that we always consider the last date to be smaller than the current commit's and always think commits are interesting. Change the initial value to the macro that gives us the maximum value on each platform so we can accurately consider commits interesting or not.

At line 594, we do this : if (error < 0) return error; but if nothing was pushed in a GIT_SORT_TIME revwalk, we'd return uninitialized stack data.

The contition cannot be reached with `commit->uninteresting` being true: either a `break` or a `continue` statement will be hit in this case.

Currently we fail to clear the sorting flag for revwalks when resetting. This caused a poor interaction with the limited flag during a recent patch. This patch clears the revwalk sorting flag and causes it to no longer persist over resets.

When we want to limit our graphwalk, we use the heuristic of checking whether the newest limiting (uninteresting) revision is newer than the oldest interesting revision. We do so by inspecting whether the first item's commit time of the user-supplied list of revisions is newer than the last added interesting revision. This is wrong though, as the user supplied list is in no way guaranteed to be sorted by increasing commit dates. This could lead us to abort the revwalk early before applying all relevant limiting revisions, outputting revisions which should in fact have been hidden. Fix the heuristic by instead checking whether _any_ of the limiting commits was made earlier than the last interesting commit. Add a test.

We don't currently need to have anything that's different between `get_revision` and `get_one_revision` so let's just remove the inner function and make the code more straightforward.

As part of reducing our divergence from git, its code for revwalk was ported into our codebase. A detail about when to limit the list was lost and we ended up always calling that code. Limiting the list means performing the walk and creating the final list of commits to be output during the preparation stage. This is unavoidable when sorting and when there are negative refs. We did this even when asked for unsorted output with no negative refs, which you might do to retrieve something like the "last 10 commits on HEAD" for a nominally unsorted meaning of "last". This commit adds and sets a flag indicating when we do need to limit the list, letting us avoid doing so when we can. The previously mentioned query thus no longer loads the entire history of the project during the prepare stage, but loads it iteratively during the walk.

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.
