[GSOC PATCH 0/2] builtin/prune: remove dependency on global variables and 'the_repository'

[Ayush Chandekar]

The aim of this patch series is to remove the definition '#define USE_THE_REPOSITORY_VARIABLE' 
from "builtin/prune.c" by removing global variables and the global 'the_repository'.

This patch series contains two patches:

1 - Move the global variable 'repository_format_precious_objects' into 'struct repository' 
and update all affected code paths accordingly.

2 - Remove the dependency of 'the_repository' in "builtin/prunce.c", allowing the removal of 
the definition.

[GSOC PATCH 1/2] repository: move 'repository_format_precious_objects' to repo scope

[Ayush Chandekar]

The 'extensions.preciousObjects' settings when set true, prevents
operations that might drop objects from the object storage.
This setting is populated in the global variable
'repository_format_precious_objects'.
Move this global variable to repo scope by adding it to 'struct
repository' and also refactor all the occurences accordingly.

This change is part of an ongoing effort to eliminate global variables,
improve modularity and help libify the codebase.

[GSOC PATCH 2/2] builtin/prune: stop depending on 'the_repository'

[Ayush Chandekar]

Refactor builtin/prune.c to remove the dependency on the global
'the_repository'. Replace all the occurrences of 'the_repository' with
repo and thus remove the definition '#define
USE_THE_REPOSITORY_VARIABLE'

This patch appears to have gone unnoticed as it hasn't seen any
reviews yet. Resurfacing it in case it got overlooked.

Could we simply make `NULL` in the same line by the way? The readability
would be better.

Same, could we just make `name` in the same line. There is no need for
the newline right now as we change "the_repository" to "repo" which
would reduce some columns.

[GSOC PATCH v2 0/2] builtin/prune: remove dependency on global variables and 'the_repository'

[Ayush Chandekar]

The aim of this patch series is to remove the definition '#define USE_THE_REPOSITORY_VARIABLE' 
from "builtin/prune.c" by removing global variables and the global 'the_repository'.

This patch series contains two patches:

1 - Move the global variable 'repository_format_precious_objects' into 'struct repository' 
and update all affected code paths accordingly.

2 - Remove the dependency of 'the_repository' in "builtin/prunce.c", allowing the removal of 
the definition.

[GSOC PATCH v2 1/2] repository: move 'repository_format_precious_objects' to repo scope

[Ayush Chandekar]

The 'extensions.preciousObjects' setting when set true, prevents
operations that might drop objects from the object storage.
This setting is populated in the global variable
'repository_format_precious_objects'.
Move this global variable to repo scope by adding it to struct
`repository` and also refactor all the occurences accordingly.

This change is part of an ongoing effort to eliminate global variables,
improve modularity and help libify the codebase.

Tiny nit: the line wrapping of this paragraph is a bit weird -- it
should generally wrap at 72 characters and paragraphs are typically
separated from one another by an empty newline.

The list of variables that we copy from `format` grows longer and
longer. I wonder whether it would make sense to embed a `struct
repository_format` in the repository and then copy over the whole
structure?

Does this work correctly when running outside of a repository? In
general `cmd_prune()` is not executed and would instead die as it is
declared as `RUN_SETUP`, without the `_GENTLY` suffix. But when the user
asks for help we may still execute the function with a NULL pointer.

Good eyes.  "git prune -h" would safely exit in parse_options() in
such a case, but this part happens before the parse_options() call.

Thanks for pointing that out, Patrick. Right now, `parse_options()` is
called just after the `repo_init_revisions()`. I can move the call to
it before this.

Although when I tried running "git prune -h", it still gave me the
expected output.

Yeah, I suggested this in a discussion with my mentors and was
expecting comments regarding the same. I can create a new patch for
this change if there's consensus on this.

Do try this outside a repo, i.e outside a git repository and try to
run the all the test if it works.

Well, as long as it works and as long as we have a test somewhere that
ensures it keeps working I'm happy.

You could also do it as a follow-up change after this series has landed.
That would be perfectly fine with me.

To add to the testing part, I noticed that there is no test for
checking "git prune -h".

You(Ayush) can add that in "t/t1517-outside-repo.sh" there is a
similar test for that also in the file.
"test_expect_success 'update-server-info does not crash with -h" You
can check it out.

Aha, TIL! I’ve been working on an (unpublished) series to make help-all work outside repos, too, and I am going to add tests. This will be a nice place.

Hey Usman,

Thanks a lot for suggesting the test file. Will include it in the
updated version of this patch series.

[GSOC PATCH v3 0/2] builtin/prune: remove dependency on global variables and 'the_repository'

[Ayush Chandekar]

The aim of this patch series is to remove the definition '#define USE_THE_REPOSITORY_VARIABLE' 
from "builtin/prune.c" by removing global variables and the global 'the_repository'.

This patch series contains two patches:

1 - Move the global variable 'repository_format_precious_objects' into 'struct repository' 
and update all affected code paths accordingly.

2 - Remove the dependency of 'the_repository' in "builtin/prunce.c", allowing the removal of 
the definition. Also, add a test to check if 'git prune -h' can be run when repository is 'NULL'.

[GSOC PATCH v3 1/2] repository: move 'repository_format_precious_objects' to repo scope

[Ayush Chandekar]

The 'extensions.preciousObjects' setting when set true, prevents
operations that might drop objects from the object storage. This setting
is populated in the global variable
'repository_format_precious_objects'.

Move this global variable to repo scope by adding it to 'struct
repository and also refactor all the occurences accordingly.

This change is part of an ongoing effort to eliminate global variables,
improve modularity and help libify the codebase.
