Hi,
this patch series refactors "object-file.c" to get rid of the dependency
on `the_repository`. In many such cases this is done by passing in a
`struct odb_source`, which prepares us for eventually converting this
into the "loose" object source with pluggable object databases.
The patch series is built on top of a30f80fde92 (The eighth batch,
2025-07-08) with "ps/object-store" at 841a03b4046 (odb: rename
`read_object_with_reference()`, 2025-07-01) merged into it.
Thanks!
Patrick

There are some trivial -Wsign-compare warnings in "object-file.c". Fix
them and drop the preprocessor define that disables those warnings.

There are a couple of users of the `the_hash_algo` macro, which
implicitly depends on `the_repository`. Adapt these callers to not do so
anymore, either by deriving it from already-available context or by
using `the_repository->hash_algo`. The latter variant doesn't yet help
to remove the global dependency, but such users will be adapted in the
following commits to not use `the_repository` anymore, either.

We implicitly depend on `the_repository` in `has_loose_object()`.
Refactor the function to accept an `odb_source` as input that should be
checked for such a loose object.
This refactoring changes semantics of the function to not check the
whole object database for such a loose object anymore, but instead we
now only check that single source. Existing callers thus need to loop
through all sources manually now.
While this change may seem illogical at first, whether or not an object
exists in a specific format should be answered by the source using that
format. As such, we can eventually convert this into a generic function
`odb_source_has_object()` that simply checks whether a given object
exists in an object source. And as we will know about the format that
any given source uses it allows us to derive whether the object exists
in a given format.
This change also makes `has_loose_object_nonlocal()` obsolete. The only
caller of this function is adapted so that it skips the primary object
source.

The `check_and_freshen()` functions are only used by a single caller
now. Inline them into `freshen_loose_object()`.
While at it, rename `check_and_freshen_odb()` to `_source()` to reflect
that it works on a single object source instead of on the whole database.

We implicitly depend on `the_repository` when freshening either loose or
packed objects. Refactor these functions to instead accept an object
database as input so that we can get rid of the global dependency.

While `loose_object_info()` already accepts a repository as parameter we
still have one callsite in there where we use `the_repository` to figure
out the hash algorithm. Use the passed-in repository instead.

We implicitly depend on `the_repository` when moving an object file into
place in `finalize_object_file()`. Get rid of this global dependency by
passing in a repository.
Note that one might be pressed to inject an object database instead of a
repository. But the function doesn't really care about the ODB at all.
All it does is to move a file into place while checking whether there is
any collision. As such, the functionality it provides is independent of
the object database and only needs the repository as parameter so that
it can adjust permissions of the file we are about to finalize.

To: git
When a repository is configured to have a compatibility hash algorithm
we keep track of object ID mappings for loose objects via the loose
object map. This map simply maps an object ID of the actual hash to the
object ID of the compatibility hash. This loose object map is an
inherent property of the loose files backend and thus of one specific
object source.
Refactor the interfaces to reflect this by requiring a `struct
odb_source` as input instead of a repository. This prepares for
subsequent commits where we will refactor writing of loose objects to
work on a `struct odb_source`, as well.

From: Patrick Steinhardt @ 2025-07-09 11:17 UTC (permalink / raw)
To: git
We do not have a backend-agnostic way to write objects into an object
database. While there is `write_object_file()`, this function is rather
specific to the loose object format.
Introduce `odb_write_object()` to plug this gap. For now, this function
is a simple wrapper around `write_object_file()` and doesn't even use
the passed-in object database yet. This will change in subsequent
commits, where `write_object_file()` is converted so that it works on
top of an `odb_source`. `odb_write_object()` will then become
responsible for deciding which source an object shall be written to.

The logic that writes loose objects still relies on `the_repository` to
decide where exactly the object shall be written to. Refactor it so that
the logic instead operates on a `struct odb_source` so that we can get
rid of this global dependency.

The function `for_each_loose_file_in_objdir_buf()` is declared in our
headers, but it is not used anywhere else than in the corresponding code
file itself. Drop the declaration and inline the function into its only
caller.

To: git
The iterators for loose objects still rely on `the_repository`. Refactor
them:
- `for_each_loose_file_in_objdir()` is refactored so that the caller
is now expected to pass an `odb_source` as parameter instead of the
path to that source. Furthermore, it is renamed accordingly to
`for_each_loose_file_in_source()`.
- `for_each_loose_object()` is refactored to take in an object
database now and calls the above function in a loop.
This allows us to get rid of the global dependency.
Adjust callers accordingly.

The function `read_loose_object()` takes a path to an object file and
tries to parse it. As such, the function does not depend on any specific
object database but instead acts as an ODB-independent way to read a
specific file. As such, all it needs as input is a repository so that we
can derive repo settings and the hash algorithm.
That repository isn't passed in as a parameter though, as we implicitly
depend on the global `the_repository`. Refactor the function so that we
pass in the repository as a parameter.

The function `force_object_loose()` forces an object to become a loose
object in case it only exists in its packed form. To do so it implicitly
relies on `the_repository`.
Refactor the function by passing a `struct odb_source` as parameter.
While the check whether any such loose object exists already acts on the
whole object database, writing the loose object happens in one specific
source.

Both `index_fd()` and `index_path()` still use `the_repository` even
though they have a repository available via `struct index_state`. Adapt
them so that they use the index' repository instead to get rid of this
global dependency.

To: git
The compression level for loose objects and packfiles is tracked via a
couple of global variables. Refactor these so that the values for them
are tracked via repo settings, which allows us to drop this global
dependency.
Note that the refactoring is mostly straight-forward, except in
git-pack-objects(1). Here it is possible to change the compression level
via a command line option, and that option of course should override
whatever the user has configured. This creates the problem that we need
to be able to see whether the option has been given in the first place.
This is done by using `INT_MIN` as default value. Any value smaller than
-1 is an invalid compression level, so it's quite unlikely that any user
ever passed that sentinel value. And if they did we would have died
anyway.

The object creation mode controls whether we use hardlinks or renames to
move objects into place. The value for that config is stored in a global
variable, which is bad practice nowadays.
Refactor the config value so that it is instead tracked via our repo
settings.

We do not depend on any global state anymore in "object-file.c", so we
can now get rid of the USE_THE_REPOSITORY_VARIABLE preprocessor macro.
Remove it.

The delayed config parsing causes a user visible regression in
fast-import. If I run
$ git fast-export HEAD^ | git -c core.compression=500 fast-import
it dies with
fatal: bad zlib compression level 500
With this series applied I see
fatal: bad zlib compression level 500
fast-import: dumping crash report to
/home/phil/src/git/.git/worktrees/tmp2/fast_import_crash_13462
I do not think adding prepare_repo_settings() calls all over the place
is a good way forward as it makes it very easy to introduce regressions
like this. Our builtin commands parse the config at startup for good
reasons if we're going to move settings out of git_default_core_config()
we should ensure that they are still parsed at startup.
Thanks

I really enjoy seeing how your plan comes together here. So much nicer
to not pass in the path directly.

This sounds weird and like unwanted behavior, but you're not changing
that. Makes sense to me.

The 'either' doesn't make sense here.

I wonder why we add this header.
The rest of the patch looks good.

So for functions which only work on object database source, we add a
'_source' suffix. For others, it is expected to work on the database
level. Ok.

Nit: In one of the earlier commits, we renamed a function working on a
particular source to have the '_source' suffix. Should we do the same
here?
I understand that this is related to a specific source (loose files) and
probably would move into its own file under the objects namespace. But
perhaps something to think about.

I think that is a good guideline that applies not just to this
series but to other topics that attempt to move globals to a member
in struct repository (or repository_settings)

Yeah, things are still wildly inconsistent right now. This will change
once we can finally carve out the actual object source backends, at
which point we'll have to move around a bunch of functions anyway. So
I'm not yet polishing up every function.

I'm not quite sure I understand the question. This function is about
_ensuring_ that the object exists in its loose format. So if it only
exists in a packfile, it will be written in its loose format. If it
already exists as a loose object, nothing happens.

Fair enough. One thing we could do is to call `prepare_repo_settings()`
at the point in time where any repository is opened. I'll have to think
about it and will try to come up with a solution.

So... the only real solution that I can think about right now is to
start parsing the repository configuration whenever we instantiate any
repository. E.g., something like the below patch. This has the effect
that the repo settings would always be populated when we have a
repository at hand. Consequently, we wouldn't need to clutter those
`prepare_repo_settings()` calls everywhere anymore.
But there is a big question: what do we do with invalid configuration
then? Do we want to die immediately when we see such command? The answer
is probably going to be a solid "sometimes":
- Some commands must function even with an invalid configuration. At
the very least git-config(1) needs to handle this alright, as
otherwise it might be impossible to unset/change invalid
configuration. There may be other such examples.
- Not all configuration is equal. It may be perfectly fine to ignore
some configuration, but other configuration may very much be mission
critical. And whether or not configuration is important isn't really
something we can decide, as it will depend on the specific use case.
So I'm afraid that there just isn't a perfect solution here. Does it
make sense to die due to a config key that isn't even used by a specific
command? Maybe. And if not, which config keys _should_ make us die in
case they are invalid?
The overall situation right now is a proper mess: we have config parsing
cluttered everywhere, and the behaviour is just plain inconsistent. Some
parsing is delayed, some isn't. Some is per-repo, some is last-one-wins.
Some config keys will cause us to die in case they are misconfigured,
some will just be ignored.
So where do we want to end up?
My dream would be that all configuration were to be defined in one
central place. The configuration should be typed, there should be
verification for each value configured by the user. All configuration
gets parsed into a structure, and it can be parsed either via a
repository (in which case we take into account its local config), or
only via the global- and system-wide configuration. The whole config
needs to be parsed at startup so that issues like the reported one don't
happen where a subprocess that uses more config keys than the parent
process dies because one of the extra keys is misconfigured.
But I very much feel like this is a pipe dream right now. We already are
working on multiple fronts to modernize the code base, and I don't quite
feel like opening up _another_ large transformation right now.
So I don't quite know what to do while we're not there yet. Without this
large refactoring, all approaches feel like they aren't a perfect fit to
address the bigger issue.
Patrick

The way I understand Karthik's question: We check all the odb->sources
for the object, so Karthik assumes (rightfully) one of the sources will
have the object, and thus the function early returns.
But when I look at the implementation of has_loose_object() it
eventually calls odb_loose_path() to find the object. So we check all
sources, but check if it exists in loose form only.
From the commit message:
> While the check whether any such loose object exists already acts on the

> source.
I must admit this last sentence from commit message now also makes more
sense to me.

Indeed. My objection here was that we were delaying the parsing when it
wasn't delayed before. Is it feasible to call prepare_repo_settings() in
repo_config()? That would at least avoid the problem that moving config
settings into `struct repo_settings` changes when the settings are
parsed unless the command calls prepare_repo_settings() at start up. As
far as I remember `git config` uses config_with_options() so that would
not be adversely affected by such a change.

Being able to verify config settings when they're set would be a great
improvement but we're a long way from being able to do that.

I agree addressing all the shortcomings you've outlined would require a
lot of refactoring. If we can find a way to avoid introducing anymore
shortcomings as we migrate away from global variables that would be a
good start.

Hm, yeah, I think adding it to `repo_config()` might be a viable
approach. I'll give it a try tomorrow and see what breaks :)
Thanks!

Yes, and there always are end-user or third-party defined keys that
are not known to us, and we cannot tell if an unknown variable is
such a end-user defined one or a typo. I do not know if it is
feasible to aim for that.

The answer is "quite a lot". I'm now 15 patches deep to try and fix
this and am nowhere close to a working state yet. The single biggest
issue is `core.shared_repository`, which is used in a ton of places and
which causes all kinds of pain.
I think I'll stop working on this for now, and would rather like to drop
the last three patches from this series so that we can move forward with
it.

Hi,
this patch series refactors "object-file.c" to get rid of the dependency
on `the_repository`. In many such cases this is done by passing in a
`struct odb_source`, which prepares us for eventually converting this
into the "loose" object source with pluggable object databases.
The patch series is built on top of a30f80fde92 (The eighth batch,
2025-07-08) with "ps/object-store" at 841a03b4046 (odb: rename
`read_object_with_reference()`, 2025-07-01) merged into it.
Changes in v2:
- Two small typo improvements.
- Drop the last three patches from this series that move some global
config into repo settings. Those cause a change in behaviour, and
fixing that is a lot of effort that falls outside of the scope of
this patch series.
- Link to v1: https://lore.kernel.org/r/20250709-pks-object-file-wo-the-repository-v1-0-62627b55707f@pks.im
Thanks!
Patrick

them and drop the preprocessor define that disables those warnings.

There are a couple of users of the `the_hash_algo` macro, which
implicitly depends on `the_repository`. Adapt these callers to not do so
anymore, either by deriving it from already-available context or by
using `the_repository->hash_algo`. The latter variant doesn't yet help
to remove the global dependency, but such users will be adapted in the
following commits to not use `the_repository` anymore.

We implicitly depend on `the_repository` in `has_loose_object()`.
Refactor the function to accept an `odb_source` as input that should be
checked for such a loose object.
This refactoring changes semantics of the function to not check the
whole object database for such a loose object anymore, but instead we
now only check that single source. Existing callers thus need to loop
through all sources manually now.
While this change may seem illogical at first, whether or not an object
exists in a specific format should be answered by the source using that
format. As such, we can eventually convert this into a generic function
`odb_source_has_object()` that simply checks whether a given object
exists in an object source. And as we will know about the format that
any given source uses it allows us to derive whether the object exists
in a given format.
This change also makes `has_loose_object_nonlocal()` obsolete. The only
caller of this function is adapted so that it skips the primary object
source.

The `check_and_freshen()` functions are only used by a single caller
now. Inline them into `freshen_loose_object()`.
While at it, rename `check_and_freshen_odb()` to `_source()` to reflect
that it works on a single object source instead of on the whole database.

database as input so that we can get rid of the global dependency.

While `loose_object_info()` already accepts a repository as parameter we
still have one callsite in there where we use `the_repository` to figure
out the hash algorithm. Use the passed-in repository instead.

We implicitly depend on `the_repository` when moving an object file into
place in `finalize_object_file()`. Get rid of this global dependency by
passing in a repository.
Note that one might be pressed to inject an object database instead of a
repository. But the function doesn't really care about the ODB at all.
All it does is to move a file into place while checking whether there is
any collision. As such, the functionality it provides is independent of
the object database and only needs the repository as parameter so that
it can adjust permissions of the file we are about to finalize.

When a repository is configured to have a compatibility hash algorithm
we keep track of object ID mappings for loose objects via the loose
object map. This map simply maps an object ID of the actual hash to the
object ID of the compatibility hash. This loose object map is an
inherent property of the loose files backend and thus of one specific
object source.
Refactor the interfaces to reflect this by requiring a `struct
odb_source` as input instead of a repository. This prepares for
subsequent commits where we will refactor writing of loose objects to
work on a `struct odb_source`, as well.

We do not have a backend-agnostic way to write objects into an object
database. While there is `write_object_file()`, this function is rather
specific to the loose object format.
Introduce `odb_write_object()` to plug this gap. For now, this function
is a simple wrapper around `write_object_file()` and doesn't even use
the passed-in object database yet. This will change in subsequent
commits, where `write_object_file()` is converted so that it works on
top of an `odb_source`. `odb_write_object()` will then become
responsible for deciding which source an object shall be written to.

From: Patrick Steinhardt @ 2025-07-17 4:56 UTC (permalink / raw)
To: git; +Cc: Phillip Wood, Junio C Hamano, Karthik Nayak, Toon Claes
The logic that writes loose objects still relies on `the_repository` to
decide where exactly the object shall be written to. Refactor it so that
the logic instead operates on a `struct odb_source` so that we can get
rid of this global dependency.

The function `for_each_loose_file_in_objdir_buf()` is declared in our
headers, but it is not used anywhere else than in the corresponding code
file itself. Drop the declaration and inline the function into its only
caller.

The iterators for loose objects still rely on `the_repository`. Refactor
them:
- `for_each_loose_file_in_objdir()` is refactored so that the caller
is now expected to pass an `odb_source` as parameter instead of the
path to that source. Furthermore, it is renamed accordingly to
`for_each_loose_file_in_source()`.
- `for_each_loose_object()` is refactored to take in an object
database now and calls the above function in a loop.
This allows us to get rid of the global dependency.
Adjust callers accordingly.

The function `read_loose_object()` takes a path to an object file and
tries to parse it. As such, the function does not depend on any specific
object database but instead acts as an ODB-independent way to read a
specific file. As such, all it needs as input is a repository so that we
can derive repo settings and the hash algorithm.
That repository isn't passed in as a parameter though, as we implicitly
depend on the global `the_repository`. Refactor the function so that we
pass in the repository as a parameter.

The function `force_object_loose()` forces an object to become a loose
object in case it only exists in its packed form. To do so it implicitly
relies on `the_repository`.
Refactor the function by passing a `struct odb_source` as parameter.
While the check whether any such loose object exists already acts on the
whole object database, writing the loose object happens in one specific
source.

Both `index_fd()` and `index_path()` still use `the_repository` even
though they have a repository available via `struct index_state`. Adapt
them so that they use the index' repository instead to get rid of this
global dependency.

This is exactly what came to my mind too while reading Patrick's message.
As the global variables which were shifted to `struct repo_settings`
were once parsed by repo_config(), we would have no problem calling
prepare_repo_settings() inside it as the behaviour would be the same
as before, and it checks if the repository is null too.

Yeah, thanks for taking a look. I think shrinking the size of the
series is sensible. It is easier to manage larger number of smaller
patch series than a single large series.
Thanks, both.
