The function `refs_head_ref_namespaced()` is somewhat special when
compared to most of the other functions that take a callback function:
while `refs_for_each_*()` functions yield multiple refs, we only yield
at most the HEAD ref of the current function. As such, the function is
related to `refs_head_ref()` and not to the for-each functions.
Move the function to be located next to `refs_head_ref()` to clarify.

Move the `do_for_each_ref_flags` enum further up. This prepares for
subsequent changes, where the flags will be used by more functions.

The enum `do_for_each_ref_flags` and its individual values don't match
to our current best practices when it comes to naming things. Rename it
to `refs_for_each_flag`.

Right, that makes sense indeed. I've queued that change locally and will
send it out with the next version, thanks!

In the refs subsystem we have a proliferation of functions that all
iterate through references. (Almost) all of these functions internally
call `do_for_each_ref()` and provide slightly different arguments so
that one can control different aspects of its behaviour. This approach
doesn't really scale: every time there is a slightly different use case
for iterating through refs we create another new function.
This combinatorial explosion doesn't make a lot of sense: it leads to
confusing interfaces and heightens the maintenance burden.
Refactor the code to become more composable by:
- Exposing `do_for_each_ref()` as `refs_for_each_ref_ext()`.
- Introducing an options structure that lets the caller control
individual options.
This gives us a much better foundation to build on going forward.

So instead of passing prefix, exclude_patterns and trim, we pass in a
struct which contains the options. Ok.
We also rename fn to cb, since that is more legible.

Then we modify all the callees to use the new options struct instead of
passing in the arguments individually. Seems good.

The function `refs_for_each_glob_ref_in()` can be used to iterate
through all refs in a specific prefix with globbing. The logic to handle
this is currently hosted by `refs_for_each_glob_ref_in()`, which sets up
a callback function that knows to filter out refs that _don't_ match the
given globbing pattern.
The way we do this is somewhat inefficient though: even though the
function is expected to only yield refs in the given prefix, we still
end up iterating through _all_ references, regardless of whether or not
their name matches the given prefix.
Extend `refs_for_each_ref_ext()` so that it can handle patterns and
adapt `refs_for_each_glob_ref_in()` to use it. This means we continue to
use the same callback-based infrastructure to filter individual refs via
the globbing pattern, but we can now also use the other functionality of
the `_ext()` variant.
Most importantly, this means that we now properly handle the prefix.
This results in a performance improvement when using a prefix where a
significant majority of refs exists outside of the prefix. The following
benchmark is an extreme case, with 1 million refs that exist outside the
prefix and a single ref that exists inside it:
Benchmark 1: git rev-parse --branches=refs/heads/* (rev = HEAD~)
Time (mean ± σ): 115.9 ms ± 0.7 ms [User: 113.0 ms, System: 2.4 ms]

So currently instead of relying on the backends to do the prefix

So this change, ensures we don't do the filtering for prefix match
ourselves and allows the backend to do it.

No, unfortunately not. This is because the glob pattern is expected to
match on the full refname, so if we were to strip the refname before we
pass it to the `filter` callback then we wouldn't be able to do the call
to wildmatch anymore.
But the stripping part is still a bit funky after my refactoring, as we
unconditionall strip the prefix right now. This is the expected
behaviour, but it is somewhat surprising I guess. I'll rework this part
a bit, thanks!

The function `refs_for_each_namespaced_ref()` iterates through all
references that are part of the current ref namespace. This namespace
can be configured by setting the `GIT_NAMESPACE` environment variable
and is then retrieved by calling `get_git_namespace()`.
If a namespace is configured, then we:
- Obviously only yield refs that exist in this namespace.
- Rewrite exclude patterns so that they work for the given namespace,
if any namespace is currently configured.
Port this logic to `refs_for_each_ref_ext()` by adding a new `namespace`
field to the options structure. This gives callers more flexibility as
they can decide by themselves whether they want to use the globally
configured or an arbitrary other namespace.

So if the namespace is 'foo', we'll have the namespace folder as
'refs/namespace/foo', and a prefix of 'refs/heads/' would mean that the
'namespaced_prefix' is now 'refs/namespace/foo/refs/heads'. Looks good.

The function `refs_for_each_fullref_in_prefixes()` can be used to
iterate over all references part of any of the user-provided prefixes.
In contrast to the `prefix` parameter of `refs_for_each_ref_ext()` it
knows to handle the case well where multiple of the passed-in prefixes
start with a common prefix by computing longest common prefixes and then
iterating over those.
While we could move this logic into `refs_for_each_ref_ext()`, this one
feels somewhat special as we perform multiple iterations. But what we
_can_ do is to generalize how this function works: instead of accepting
only a small handful of parameters, we can have it accept the full
options structure.
One obvious exception is that the caller must not provide a prefix via
the options. But this case can be easily detected.
Refactor the code accordingly.

I've attempted the refactoring that this series is doing a couple of
times, I always got stuck up on how to integrate this function with the
rest. This is a novel approach.

Okay so it still calls `refs_for_each_ref_ext()` on the longest prefix.
Makes sense.

Improve verification of the passed-in for-each-ref options:
- Require that the `refs` store must be given. It's arguably very
surprising that we simply return successfully in case the ref store
is a `NULL` pointer.
- When expected to trim ref prefixes we will `BUG()` in case the
refname would become empty or in case we're expected to trim a
longer prefix than the refname is long. As such, this case is only
guaranteed to _not_ `BUG()` in case the caller also specified a
prefix. And furthermore, that prefix must end in a trailing slash,
as otherwise it may produce an exact match that could lead us to
trim to the empty string.
An audit shows that there are no callsites that rely on either of these
behaviours, so this should not result in a functional change.

Nit: s/refs/ref store/, mostly from a readability point, but since this
is a BUG(), I think its okay to leave as is.

I'm really happy with the patches, I have some small nits/questions, but
it looks good otherwise.

Hi,
we currently have 14 different `refs_for_each_*()` functions, with each
of them doing slightly different things. This makes for a confusing API
surface, and because the API is not built for extension we have to add a
new function every now and then to handle another esoteric edge case
that will ultimately only have at most a handful of callers.
This design isn't really sensible in my opinion, and this patch series
aims to fix that. Instead of having a dozen different functions, it
introduces a new `refs_for_each_ref_ext()` function that simply takes an
options structure as input. From thereon, callers can mix and match the
parameters that they care about.
The patch series is structured like this:
- Patches 1 to 5 introduce some preliminary cleanups.
- Patches 6 to 9 introduce `refs_for_each_ref_ext()` and move
more functionality into it. This also fixes a performance bug that
we have in one of the implementations.
- Patch 10 adds some more verification for options that would have
caught the bugs in ps/for-each-ref-in-fixes.
- The remaining patches drop 7 out of 14 functions and replace them
with `refs_for_each_ref_ext()`. It results in a bit of churn, so
while I think this churn is worth it, I consider these patches to be
optional.
The patch series is built on top of 73fd77805f (The 5th batch,
2026-02-17) with ps/for-each-ref-in-fixes at 6375a00ef1 (bisect:
simplify string_list memory handling, 2026-02-19) merged into it.
Changes in v2:
- Move the removal of `refs_for_each_include_root_ref()` to the
beginning of the series to avoid some unnecessary churn.
- Some commit message improvements.
- Make the converted version of `refs_for_each_glob_ref_in()` fit into
the new calling conventions a bit better. The function was still
stripping the prefix unconditionally for example, which I've now
changed.
- Link to v1: https://lore.kernel.org/r/20260220-pks-refs-for-each-unification-v1-0-17170bd99de1@pks.im
Thanks!
Patrick

@@ Commit message
The function `refs_head_ref_namespaced()` is somewhat special when
compared to most of the other functions that take a callback function:
- while `refs_for_each_*()` functions yield multiple refs, we only yield
- at most the HEAD ref of the current function. As such, the function is
- related to `refs_head_ref()` and not to the for-each functions.
+ while `refs_for_each_*()` functions yield multiple refs,
+ `refs_heasd_ref_namespaced()` will only yield at most the HEAD ref of
+ the current namespace. As such, the function is related to
+ `refs_head_ref()` and not to the for-each functions.
Move the function to be located next to `refs_head_ref()` to clarify.

The function `refs_head_ref_namespaced()` is somewhat special when
compared to most of the other functions that take a callback function:
while `refs_for_each_*()` functions yield multiple refs,
`refs_heasd_ref_namespaced()` will only yield at most the HEAD ref of
the current namespace. As such, the function is related to
`refs_head_ref()` and not to the for-each functions.
Move the function to be located next to `refs_head_ref()` to clarify.

Move the `do_for_each_ref_flags` enum further up. This prepares for
subsequent changes, where the flags will be used by more functions.

The enum `do_for_each_ref_flags` and its individual values don't match
to our current best practices when it comes to naming things. Rename it
to `refs_for_each_flag`.

Similar to the preceding commit, rename `each_ref_fn` to better match
our current best practices around how we name things.

17 siblings, 0 replies; 53+ messages in thread
From: Patrick Steinhardt @ 2026-02-23 11:59 UTC (permalink / raw)
To: git; +Cc: Karthik Nayak, Oswald Buddenhagen
In the refs subsystem we have a proliferation of functions that all
iterate through references. (Almost) all of these functions internally
call `do_for_each_ref()` and provide slightly different arguments so
that one can control different aspects of its behaviour. This approach
doesn't really scale: every time there is a slightly different use case
for iterating through refs we create another new function.
This combinatorial explosion doesn't make a lot of sense: it leads to
confusing interfaces and heightens the maintenance burden.
Refactor the code to become more composable by:
- Exposing `do_for_each_ref()` as `refs_for_each_ref_ext()`.
- Introducing an options structure that lets the caller control
individual options.
This gives us a much better foundation to build on going forward.

The function `refs_for_each_glob_ref_in()` can be used to iterate
through all refs in a specific prefix with globbing. The logic to handle
this is currently hosted by `refs_for_each_glob_ref_in()`, which sets up
a callback function that knows to filter out refs that _don't_ match the
given globbing pattern.
The way we do this is somewhat inefficient though: even though the
function is expected to only yield refs in the given prefix, we still
end up iterating through _all_ references, regardless of whether or not
their name matches the given prefix.
Extend `refs_for_each_ref_ext()` so that it can handle patterns and
adapt `refs_for_each_glob_ref_in()` to use it. This means we continue to
use the same callback-based infrastructure to filter individual refs via
the globbing pattern, but we can now also use the other functionality of
the `_ext()` variant.
Most importantly, this means that we now properly handle the prefix.
This results in a performance improvement when using a prefix where a
significant majority of refs exists outside of the prefix. The following
benchmark is an extreme case, with 1 million refs that exist outside the
prefix and a single ref that exists inside it:
Benchmark 1: git rev-parse --branches=refs/heads/* (rev = HEAD~)
Time (mean ± σ): 115.9 ms ± 0.7 ms [User: 113.0 ms, System: 2.4 ms]
Range (min … max): 114.9 ms … 117.8 ms 25 runs
Benchmark 2: git rev-parse --branches=refs/heads/* (rev = HEAD)
Time (mean ± σ): 1.1 ms ± 0.1 ms [User: 0.3 ms, System: 0.7 ms]
Range (min … max): 1.0 ms … 2.3 ms 2092 runs
Summary
git rev-parse --branches=refs/heads/* (rev = HEAD) ran
107.01 ± 6.49 times faster than git rev-parse --branches=refs/heads/* (rev = HEAD~)

The function `refs_for_each_namespaced_ref()` iterates through all
references that are part of the current ref namespace. This namespace
can be configured by setting the `GIT_NAMESPACE` environment variable
and is then retrieved by calling `get_git_namespace()`.
If a namespace is configured, then we:
- Obviously only yield refs that exist in this namespace.
- Rewrite exclude patterns so that they work for the given namespace,
if any namespace is currently configured.
Port this logic to `refs_for_each_ref_ext()` by adding a new `namespace`
field to the options structure. This gives callers more flexibility as
they can decide by themselves whether they want to use the globally
configured or an arbitrary other namespace.

The function `refs_for_each_fullref_in_prefixes()` can be used to
iterate over all references part of any of the user-provided prefixes.
In contrast to the `prefix` parameter of `refs_for_each_ref_ext()` it
knows to handle the case well where multiple of the passed-in prefixes
start with a common prefix by computing longest common prefixes and then
iterating over those.
While we could move this logic into `refs_for_each_ref_ext()`, this one
feels somewhat special as we perform multiple iterations. But what we
_can_ do is to generalize how this function works: instead of accepting
only a small handful of parameters, we can have it accept the full
options structure.
One obvious exception is that the caller must not provide a prefix via
the options. But this case can be easily detected.
Refactor the code accordingly.

Improve verification of the passed-in for-each-ref options:
- Require that the `refs` store must be given. It's arguably very
surprising that we simply return successfully in case the ref store
is a `NULL` pointer.
- When expected to trim ref prefixes we will `BUG()` in case the
refname would become empty or in case we're expected to trim a
longer prefix than the refname is long. As such, this case is only
guaranteed to _not_ `BUG()` in case the caller also specified a
prefix. And furthermore, that prefix must end in a trailing slash,
as otherwise it may produce an exact match that could lead us to
trim to the empty string.
An audit shows that there are no callsites that rely on either of these
behaviours, so this should not result in a functional change.

The range-diff looks good. I'm happy with this version! :)
