5265b31c	2019-01-23T15:00:20	streams: fix callers potentially only writing partial data Similar to the write(3) function, implementations of `git_stream_write` do not guarantee that all bytes are written. Instead, they return the number of bytes that actually have been written, which may be smaller than the total number of bytes. Furthermore, due to an interface design issue, we cannot ever write more than `SSIZE_MAX` bytes at once, as otherwise we cannot represent the number of bytes written to the caller. Unfortunately, no caller of `git_stream_write` ever checks the return value, except to verify that no error occurred. Due to this, they are susceptible to the case where only partial data has been written. Fix this by introducing a new function `git_stream__write_full`. In contrast to `git_stream_write`, it will always return either success or failure, without returning the number of bytes written. Thus, it is able to write all `SIZE_MAX` bytes and loop around `git_stream_write` until all data has been written. Adjust all callers except the BIO callbacks in our mbedtls and OpenSSL streams, which already do the right thing and require the amount of bytes written.

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.

c180c065	2014-07-09T17:58:39	Custom transport: minor cleanups * Move the transport registration mechanisms into a new header under 'sys/' because this is advanced stuff. * Remove the 'priority' argument from the registration as it adds unnecessary complexity. (Since transports cannot decline to operate, only the highest priority transport is ever executed.) Users who require per-priority transports can implement that in their custom transport themselves. * Simplify registration further by taking a scheme (eg "http") instead of a prefix (eg "http://").

As a result, places that relied on intercepting GIT_EUSER but having the old error preserved also needed to be cleaned up to correctly stash and then retrieve the actual error. Additionally, as I encountered places where error codes were not being propagated correctly, I tried to fix them up. A number of those fixes are included in the this commit as well.

The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules.

This fix seperates the error code and socket in gitno_connect(), and fixes the error handling in do_connect() functions to compensate. It appears that git_connect() and the git-transport do_connect() functions had bugs in the non-windows cases too (leaking sockets, and not properly reporting connection error, respectively) so I went ahead and fixed those too.
