* str: introduce `git_str` for internal, `git_buf` is externalethomson/gitstrEdward Thomson2021-10-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | Docurium seems to be confused by our use of `/** comment */;` use in the log example. Let's just switch it around to help Docurium get this right.
* strarray: we should `dispose` instead of `free`Edward Thomson2020-06-014-5/+5
| | | | | | We _dispose_ the contents of objects; we _free_ objects (and their contents). Update `git_strarray_free` to be `git_strarray_dispose`. `git_strarray_free` remains as a deprecated proxy function.

* credential: change git_cred to git_credentialethomson/credtypeEdward Thomson2020-01-262-8/+8
| | | | | | | | | | | | | | | | We avoid abbreviations where possible; rename git_cred to git_credential. In addition, we have standardized on a trailing `_t` for enum types, instead of using "type" in the name. So `git_credtype_t` has become `git_credential_t` and its members have become `GIT_CREDENTIAL` instead of `GIT_CREDTYPE`. Finally, the source and header files have been renamed to `credential` instead of `cred`. Keep previous name and values as deprecated, and include the new header files from the previous ones.

Specifier used was for signed int but git_indexer_progress members are typed as unsigned ints. `printf` specifiers were altered to match type.

| * examples: avoid warning when iterating over index entriesPatrick Steinhardt2019-07-052-2/+2
| | | | | | | | | | | | | | | | When iterating over index entries, we store the indices in an unsigned int. As the index entrycount is a `size_t` though, this may be a loss of precision which a compiler might rightfully complain about. Use `size_t` instead to fix any warnings.
| * examples: avoid conversion warnings when calculating progressPatrick Steinhardt2019-07-051-3/+3
| | | | | | | | | | | | | | | | | | | | When computing the progress, we perform some arithmetics that are implicitly converting from `size_t` to `int`. In one case we're calclulating a percentage, so we know that it should always be in the range of [0,100] and thus we're fine. In the other case we convert from bytes to kilobytes -- this should be stored in a `size_t` to avoid loss of precision, even though it probably won't matter due to limited download rates.
| * examples: avoid passing signed integer to `memchr`Patrick Steinhardt2019-07-051-1/+1
| | | | | | | | | | | | | | The memchr(3P) function expects a `size_t` as its last parameter, but we do pass it an object size, which is of signed type `git_off_t`. As we can be sure that the result will be non-negative, let's just cast the parameter to a `size_t`.
| * examples: cast away constness for reallocating head arraysPatrick Steinhardt2019-07-052-2/+2
| | | | | | | | | | | | | | | | | | When reallocating commit arrays in `opts_add_commit` and `opts_add_refish`, respectively, we simply pass the const pointer to `xrealloc`. As `xrealloc` expects a non-const pointer, though, this will generate a warning with some compilers. Cast away the constness to silence compilers.

* | Resolve static check warnings in example codeScott Furry2019-06-272-1/+2
|/ | | | | | | | | | | | Using cppcheck on libgit2 sources indicated two warnings in example code. merge.c was reported as having a memory leak. Fix applied was to `free()` memory pointed to by `parents`. init.c was reported as having a null pointer dereference on variable arg. Function 'usage' was being called with a null variable. Changed supplied parameter to empty string.
* oid: `is_zero` instead of `iszero`Edward Thomson2019-06-162-3/+3
| | | | | | The only function that is named `issomething` (without underscore) was `git_oid_iszero`. Rename it to `git_oid_is_zero` for consistency with the rest of the library.
* Rename opt init functions to `options_init`Edward Thomson2019-06-141-3/+3
| | | | | | | | | | | | | In libgit2 nomenclature, when we need to verb a direct object, we name a function `git_directobject_verb`. Thus, if we need to init an options structure named `git_foo_options`, then the name of the function that does that should be `git_foo_options_init`. The previous names of `git_foo_init_options` is close - it _sounds_ as if it's initializing the options of a `foo`, but in fact `git_foo_options` is its own noun that should be respected. Deprecate the old names; they'll now call directly to the new ones.
* examples: use username provided via URLPatrick Steinhardt2019-04-161-8/+9
| | | | | | | | The credentials callback may be passed a username in case where the URL already includes the expected username. As we usually cannot use a different username in such context, we should use that one if provided and not ask the user for a diferent username.
