hook.[ch]: move find_hook() from run-command.c to hook.c

2021-09-27T16:44:54Z

Move the find_hook() function from run-command.c to a new hook.c library. This change establishes a stub library that's pretty pointless right now, but will see much wider use with Emily Shaffer's upcoming "configuration-based hooks" series. Eventually all the hook related code will live in hook.[ch]. Let's start that process by moving the simple find_hook() function over as-is.

Merge branch 'mr/bisect-in-c-4'

2021-09-23T20:44:48Z

Rewrite of "git bisect" in C continues. * mr/bisect-in-c-4: bisect--helper: retire `--bisect-next-check` subcommand bisect--helper: reimplement `bisect_run` shell function in C bisect--helper: reimplement `bisect_visualize()` shell function in C run-command: make `exists_in_PATH()` non-static t6030-bisect-porcelain: add test for bisect visualize t6030-bisect-porcelain: add tests to control bisect run exit cases

run-command: create start_bg_command

2021-09-20T15:57:58Z

Create a variation of `run_command()` and `start_command()` to launch a command into the background and optionally wait for it to become "ready" before returning. Signed-off-by: Jeff Hostetler Signed-off-by: Junio C Hamano

run-command: make `exists_in_PATH()` non-static

2021-09-13T20:37:37Z

Remove the `static` keyword from `exists_in_PATH()` function and declare the function in `run-command.h` file. The function will be used in bisect_visualize() in a later commit.

run-command: offer to close the object store before running

2021-09-09T19:56:11Z

Especially on Windows, where files cannot be deleted if _any_ process holds an open file handle to them, it is important to close the object store (releasing all handles to all `.pack` files) before running a command that might spawn a garbage collection. This scenario is so common that we frequently see the pattern of closing the object store before running auto maintenance or another Git command. Let's make this much more convenient by teaching the `run_command()` machinery a new flag to release the object store before spawning the process.

run-command: prettify the `RUN_COMMAND_*` flags

2021-09-09T19:56:11Z

The values were listed unaligned, and with powers of two spelled out in decimal. The list is easier to parse for human readers if the numbers are aligned and spelled out as powers of two (using the bit-shift operator `<<`). While at it, remove a code comment that was unclear at best, and confusing at worst. Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano

Merge branch 'jt/partial-clone-submodule-1'

2021-07-17T00:42:53Z

Prepare the internals for lazily fetching objects in submodules from their promisor remotes. * jt/partial-clone-submodule-1: promisor-remote: teach lazy-fetch in any repo run-command: refactor subprocess env preparation submodule: refrain from filtering GIT_CONFIG_COUNT promisor-remote: support per-repository config repository: move global r_f_p_c to repo struct

.h: move some _INIT to designated initializers

2021-07-01T19:31:45Z

Move *_INIT macros I'll use in a subsequent commits to designated initializers. This isn't required for those follow-up changes, but since next commits will change things in this area, let's use the modern pattern over the old one while we're at it.

run-command: refactor subprocess env preparation

2021-06-28T16:58:01Z

submodule.c has functionality that prepares the environment for running a subprocess in a new repo. The lazy-fetching code (used in partial clones) will need this in a subsequent commit, so move it to a more central location.
