-cshared
-=======
-
-Building
---------
-go 1.6+
-```
-go build -o libgogit.so -buildmode=c-shared github.com/src-d/go-git/cshared
-```
-Two files must appear: libgogit.h and libgogit.so. The second must be
-a shared library, not an ar archive (may happen when something goes wrong).
-Check the exported symbols with `nm -g`.
-
-How it works
-------------
-
-Nearly every public Go function is mirrored in the corresponding *_cshared.go
-file. struct fields are also mirrored with getters and setters. The functions
-are marked with `//export ...` "magic" cgo comment so that they appear
-in defined symbols of a shared library built with `-buildmode=c-shared`.
-
-Go pointers may not be passed out of cgo functions, so we maintain the
-two-way registry of all active Go objects mapped to `Handle`-s (`uint64`).
-Every time we need to return a reference to Go object outside, we call
-`RegisterObject(interface{})` which returns a new `Handle` or reuses
-an existing one if the object has already been registered. Then we
-return the obtained `Handle`. When we need to receive a Go object reference
-in cgo function parameters, we accept `uint64` and retrieve the `interface{}`
-with `GetObject(Handle)` which can be casted to the underlying type with a
-type assertion. When the object is no longer needed, we invoke
-`UnregisterObject(Handle)`.
-
-Although `interface{]` is just two `uintptr`-s inside, it is not a hashable
-type and we cannot use it a as key in our backward registry mapping.
-We are using the data `uintptr` as the key there. Since several distinct
-objects may exist with the same data pointer (e.g. struct and first field
-of the struct), the value of that mapping is a slice of `Handle`-s.
-
-All the mentioned service functions are goroutine- and threadsafe.
-
-`std_cshared.go` contains the cgo wrappers for standard library objects.
-
-Debugging
----------
-`c_dump_object()` prints the current state of the two-way object registry
-to stdout. `c_set_trace()` activates echoing of `RegisterObject()` and
-`UnregisterObject()` invocations.
-
-Caveats
--------
-Normally, we pass over a pointer to object as `interface{}` into `RegisterObject()`
-so that it can be mutated later. It requires the corresponding
-pointer-to-type type assertion in cgo functions. If you mess with this,
-the cgo function will, of course, panic.
-
-A cgo function is allowed to take Go's `string` parameters. `string`'s
-data must point to some memory and cgo does not copy the incoming foreign
-memory into Go memory automatically. What's worse, `string`-s are immutable
-and when you copy it, the copy points to the same memory. This means that
-if you pass in a `string` which was constructed using `malloc()`, for example,
-and later `free()` it, all Go strings created from the function parameter
-will point to the invalid memory. Actually, this allowance violates the
-cgo pointer passing rules stated just several blocks of texts
-below the example of string parameters - this is crazy, but we have to live
-with this, as usual in Go world. So, *all incoming `string`-s must be immediately
-safely copied with `CopyString()` once they are used*.
-
-Returning strings and byte slices is also funny: you have to use `C.CString` -> `*C.char`
-and additionally return the length as another result tuple member if needed.
-`C.CString` copies the memory pointed by `string` to a `malloc()`-ed region
-and it is the responsibility of the other side to `free()` it or it will leak
-otherwise.
-
-Another tricky part is in `c_std_map_get_str_str` and similar places
-where you need to return `*C.char` from an unaddressable array accessed under
-a pseudonym type through reflection. The only way I've found working
-is using `reflect.Copy` to byte slice (copy), then `CBytes` (copy) and
-finally another (copy) on the receiving side because the latter must be
-`free()`-d.
