To: git
Not too long ago, we have introduced the packfile store in b7983adb51
(packfile: introduce a new `struct packfile_store`, 2025-09-23). This
struct is responsible for managing all of our access to packfiles and is
used as one of the two sources of objects for the "files" source.
Back when I introduced this structure I didn't have the clear vision yet
that it will eventually also turn into a proper object database source,
and how exactly that infrastructure will look like. Now though it's
becoming increasingly clear that it does make sense to treat it just the
same as any of our other ODB sources.
The consequence is that the naming is now a bit out-of-date: it's just
another source and will be turned into a proper `struct odb_source` over
the next couple of commits, but it's not named accordingly.
Rename the structure to `odb_source_packed` to align it with this goal
and to bring it in line with the other sources we already have.

Looks good, I'm assuming we'll also rename drop some of the
`packfile_store_*` functions as things get cleaned up in the following
commits.

In fact not all of them, mostly because I wanted to not make the patch
series even bigger than it already is. I'll clean up stragglers in a
subsequent patch series though.

In subsequent patches we'll be turning `struct odb_source_packed` into a
proper `struct odb_source`. As a first step towards this goal, move its
struct out of "packfile.{c,h}" and into "odb/source-packed.{c,h}".
This detaches the implementation of the packfile object source from the
generic packfile code, following the same convention already used by the
"files" and "in-memory" sources.

To: git
The `struct odb_source_packed` holds a pointer to its owning parent
source. The way that Git is currently structured, this parent is always
the "files" source. In subsequent commits we're going to detangle that
so that the "packed" source doesn't have any owning parent source at
all, which makes it usable as a completely standalone source.
Detangling this mess is somewhat intricate though, and is made even more
intricate because it's not always clear which kind of source one is
holding at a specific point in time -- either the parent "files" source,
or the child "packed" source.
Make this relationship more explicit by storing a pointer to the "files"
source instead of storing a pointer to a generic `struct odb_source`.
This will help make subsequent steps a bit clearer.
Note that this is a temporary step, only. At the end of this series
we will have dropped the parent pointer completely.

Start converting `struct odb_source_packed` into a proper pluggable
`struct odb_source` by embedding the base struct and assigning it the
new `ODB_SOURCE_PACKED` type. Furthermore, wire up lifecycle management
of this source by implementing the `free` callback and taking ownership
of the chdir notifications.
Note that the packed source is not yet functional as a standalone `struct
odb_source`, as it's missing all of the callback implementations. These
will be wired up in subsequent commits.

Move the logic to prepare and reprepare the "packed" source into
"odb/source-packed.c" and wire it up as the `reprepare()` callback.
Note that "preparing" a source is not yet generic. Eventually, it would
probably make sense to turn the existing `reprepare()` callback into a
`prepare()` callback with an optional flag to force re-preparing. But
this step will be handled in a separate patch series.

In `has_object_pack()` we're checking whether a specific object exists
as part of a packfile. This is done by calling the low-level function
`find_pack_entry()`, but this function will eventually be moved into
"odb/source-packed.c" and made file-local.
Refactor the code to use `packfile_store_read_object_info()` instead.
This refactoring is functionally equivalent as that function will call
`find_pack_entry()` itself and then return immediately when it ain't got
no object info pointer as parameter.

Move the logic to read object info from a "packed" source into
"odb/source-packed.c" and wire it up as the `read_object_info()`
callback.
Note that we also move around the supporting `find_pack_entry()`, but we
still have to expose it to other callers that exist in "packfile.c".
This will be fixed in subsequent commits though, where all callers in
"packfile.c" will have been moved into "odb/source-packed.c", and at
that point we'll be able to make `find_pack_entry()` file-local again.

To: git
Move `packfile_store_freshen_object()` and from "packfile.c" into
"odb/source-packed.c" and wire it up as the `freshen_object()` callback
of the "packed" source.
Note that this removes the last external caller of `find_pack_entry()`
from "packfile.c", which means that we can now make this function
static.

From: Patrick Steinhardt @ 2026-06-04 11:25 UTC (permalink / raw)
To: git
Our interfaces used to interact with MIDXs all work on top of the
generic `struct odb_source`. This doesn't make much sense though: a MIDX
is strictly tied to the "packed" source, so passing in a generic source
gives the false sense that it may also work with a different type of
source.
Fix this conceptual weirdness and instead require the caller to pass in
a "packed" source explicitly. This also makes the next commit easier to
implement, where we drop the pointer to the "files" source in the
"packed" source.

2026-06-04 11:25 [PATCH 00/16] odb: make packed object source a proper `struct odb_source` Patrick Steinhardt
` (14 preceding siblings ...)
2026-06-04 11:25 ` [PATCH 15/16] midx: refactor interfaces to work on "packed" source Patrick Steinhardt
@ 2026-06-04 11:25 ` Patrick Steinhardt
15 siblings, 0 replies; 19+ messages in thread
From: Patrick Steinhardt @ 2026-06-04 11:25 UTC (permalink / raw)
To: git
Over the last commits we have turned the packfile store into a proper
object database source that can be used as a standalone backend. As
such, it is no longer necessary to have it coupled to the "files" parent
source.
Remove the pointer to the owning "files" source so that the "packed"
source can be used as a standalone entity.
