Revision 2057d75038541cd16debb1c55f3f897fd244965c authored by Derrick Stolee on 17 September 2020, 18:11:42 UTC, committed by Junio C Hamano on 17 September 2020, 18:30:04 UTC
The 'gc' builtin is our current entrypoint for automatically maintaining a repository. This one tool does many operations, such as repacking the repository, packing refs, and rewriting the commit-graph file. The name implies it performs "garbage collection" which means several different things, and some users may not want to use this operation that rewrites the entire object database. Create a new 'maintenance' builtin that will become a more general- purpose command. To start, it will only support the 'run' subcommand, but will later expand to add subcommands for scheduling maintenance in the background. For now, the 'maintenance' builtin is a thin shim over the 'gc' builtin. In fact, the only option is the '--auto' toggle, which is handed directly to the 'gc' builtin. The current change is isolated to this simple operation to prevent more interesting logic from being lost in all of the boilerplate of adding a new builtin. Use existing builtin/gc.c file because we want to share code between the two builtins. It is possible that we will have 'maintenance' replace the 'gc' builtin entirely at some point, leaving 'git gc' as an alias for some specific arguments to 'git maintenance run'. Create a new test_subcommand helper that allows us to test if a certain subcommand was run. It requires storing the GIT_TRACE2_EVENT logs in a file. A negation mode is available that will be used in later tests.

* or free 'prefix' and 'args' after calling this function.
*
* - magic_mask specifies what features that are NOT supported by the following
* code. If a user attempts to use such a feature, parse_pathspec() can reject
* it early.
*
* - flags specifies other things that the caller wants parse_pathspec to
* perform.
*
* - prefix and args come from cmd_* functions
*
* parse_pathspec() helps catch unsupported features and reject them politely.
* At a lower level, different pathspec-related functions may not support the
* same set of features. Such pathspec-sensitive functions are guarded with
* GUARD_PATHSPEC(), which will die in an unfriendly way when an unsupported
* feature is requested.
*
* The command designers are supposed to make sure that GUARD_PATHSPEC() never
* dies. They have to make sure all unsupported features are caught by
* parse_pathspec(), not by GUARD_PATHSPEC. grepping GUARD_PATHSPEC() should
* give the designers all pathspec-sensitive codepaths and what features they
* support.
*
* A similar process is applied when a new pathspec magic is added. The designer
* lifts the GUARD_PATHSPEC restriction in the functions that support the new
* magic. At the same time (s)he has to make sure this new feature will be
* caught at parse_pathspec() in commands that cannot handle the new magic in
* some cases. grepping parse_pathspec() should help.
