f0e693b1	2021-09-07T17:53:49	str: introduce `git_str` for internal, `git_buf` is external 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.

ead10785	2019-01-24T11:31:49	examples: create common lg2 executable Inside of our networking example code, we have a git2 executable that acts as an entry point to all the different network examples. As such, it is kind of the same like the normal git(1) executable in that it simply arbitrates to the respective subcommands. Let's extend this approach and merge all examples into a single standalone lg2 executable. Instead of building an executable for all the existing examples we have, we now bundle them all inside of the lg2 one and let them be callable via subcommands. In the process, we can get rid of duplicated library initialization, deinitialization and repository discovery code. Instead of having each subcommand handle these on its own, we simply do it inside of the single main function now.

799e22ea	2014-10-23T17:34:41	Rename git_threads_ to git_libgit2_ This describes their purpose better, as we now initialize ssl and some other global stuff in there. Calling the init function is not something which has been optional for a while now.
8d09efa2	2014-04-22T12:33:27	Use git_diff_get_stats in example/diff + refactor This takes the `--stat` and related example options in the example diff.c program and converts them to use the `git_diff_get_stats` API which nicely formats stats for you. I went to add bar-graph scaling to the stats formatter and noticed that the `git_diff_stats` structure was holding on to all of the `git_patch` objects. Unfortunately, each of these objects keeps the full text of the diff in memory, so this is very expensive. I ended up modifying `git_diff_stats` to keep just the data that it needs to keep and allowed it to release the patches. Then, I added width scaling to the output on top of that. In making the diff example program match 'git diff' output, I ended up removing an newline from the sumamry output which I then had to compensate for in the email formatting to match the expectations. Lastly, I went through and refactored the tests to use a couple of helper functions and reduce the overall amount of code there.
12e422a0	2014-04-21T16:08:05	Some doc and examples/diff.c changes I was playing with "git diff-index" and wanted to be able to emulate that behavior a little more closely with the diff example. Also, I wanted to play with running `git_diff_tree_to_workdir` directly even though core Git doesn't exactly have the equivalent, so I added a command line option for that and tweaked some other things in the example code. This changes a minor output thing in that the "raw" print helper function will no longer add ellipses (...) if the OID is not actually abbreviated.

This also creates a shared examples/common.[ch] so that useful helper funcs can be shared across examples instead of repeated.
3b5f7954	2013-10-21T13:42:42	Create git_diff_line and extend git_diff_hunk Instead of having functions with so very many parameters to pass hunk and line data, this takes the existing git_diff_hunk struct and extends it with more hunk data, plus adds a git_diff_line. Those structs are used to pass back hunk and line data instead of the old APIs that took tons of parameters. Some work that was previously only being done for git_diff_patch creation (scanning the diff content for exact line counts) is now done for all callbacks, but the performance difference should not be noticable.

This reverses the order in the function name to make it less confusing. Specifically... * git_diff_index_to_tree becomes git_diff_tree_to_index * git_diff_workdir_to_index becomes git_diff_index_to_workdir * git_diff_workdir_to_tree becomes git_diff_tree_to_workdir

This should make them consistent with other callbacks across the API.
bbe6dbec	2012-11-14T23:29:48	Add explicit git_index ptr to diff and checkout A number of diff APIs and the `git_checkout_index` API take a `git_repository` object an operate on the index. This updates them to take a `git_index` pointer explicitly and only fall back on the `git_repository` index if the index input is NULL. This makes it easier to operate on a temporary index.
b90500f0	2012-11-01T14:08:30	Improve docs, examples, warnings This improves docs in some of the public header files, cleans up and improves some of the example code, and fixes a couple of pedantic warnings in places.
145e696b	2012-06-08T11:56:24	Minor fixes, cleanups, and clarifications There are three actual changes in this commit: 1. When the trailing newline of a file is removed in a diff, the change will now be reported with `GIT_DIFF_LINE_DEL_EOFNL` passed to the callback. Previously, the `ADD_EOFNL` constant was given which was just an error in my understanding of when the various circumstances arose. `GIT_DIFF_LINE_ADD_EOFNL` is deprecated and should never be generated. A new newline is simply an `ADD`. 2. Rewrote the `diff_delta__merge_like_cgit` function that contains the core logic of the `git_diff_merge` implementation. The new version doesn't actually have significantly different behavior, but the logic should be much more obvious, I think. 3. Fixed a bug in `git_diff_merge` where it freed a string pool while some of the string data was still in use. This led to `git_diff_print_patch` accessing memory that had been freed. The rest of this commit contains improved documentation in `diff.h` to make the behavior and the equivalencies with core git clearer, and a bunch of new tests to cover the various cases, oh and a minor simplification of `examples/diff.c`.
