cf7dd05b	2020-06-30T13:26:05	refdb: return resolved symbolic refs pointing to nonexistent refs In some cases, resolving references requires us to also know about the final symbolic reference that's pointing to a nonexistent branch, e.g. in an empty repository where the main branch is yet unborn but HEAD already points to it. Right now, the resolving logic is thus split up into two, where one is the new refdb implementation and the second one is an ad-hoc implementation inside "refs.c". Let's extend `git_refdb_resolve` to also return such final dangling references pointing to nonexistent branches so we can deduplicate the resolving logic.
c54f40e4	2020-06-30T09:28:12	refs: move resolving of references into the refdb Resolving of symbolic references is currently implemented inside the "refs" layer. As a result, it's hard to call this function from low-level parts that only have a refdb available, but no repository, as the "refs" layer always operates on the repository-level. So let's move the function into the generic "refdb" implementation to lift this restriction.
1f39593b	2020-06-30T08:53:59	refdb: extract function to check whether to append HEAD to the reflog The logic to determine whether a reflog entry should be for the HEAD reference is non-trivial. Currently, the only user of this is the filesystem-based refdb, but with the advent of the reftable refdb we're going to add a second user that's interested in having the same behaviour. Let's pull out a new function that checks whether a given reference should cause a entry to be written to the HEAD reflog as a preparatory step.

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.
ab8d9242	2014-06-28T06:39:38	Introduce reference transactions A transaction allows you to lock multiple references and set up changes for them before applying the changes all at once (or as close as the backend supports). This can be used for replication purposes, or for making sure some operations run when the reference is locked and thus cannot be changed.
