Why do we except additional arguments if this option includes all the
remotes?

Yes, I find it quite useful to make a note of what the fixup is doing if
I know I'm not going to squash it for a while.

Yes, looking at the way the code is structured I wonder if these options
were made incompatible to simplify the implementation, or maybe the
implementation merely reflects those restrictions.

It is indeed unfortunate that we end up duplicating the code to read the
logfile here. I wonder how hard it would be to refactor
prepare_to_commit() so that it can accommodate "--fixup=amend:<commit> -F"

In this case it would be better to use
test_commit_message HEAD <<-EOF
amend! $(git log -1 --format=%s HEAD~)
amend commit message
EOF
and avoid creating actual and expect all together.

Sorry, I realized it's still a bit buggy when coupled with --boundary.

Expanding the message to back reference 3f763ddf28 is a nice change.
Makes it easier for future people reading the history to follow back.

Oh nice! v3 had two OPT_PASSTHRU_ARGV (one for each name). Now we're
using OPT_ALIAS here too for the old name which avoids duplicated
description strings - yay!
I had to convince myself this works (does OPT_ALIAS forward to the
passthru option?). Looking at parse-options.c, preprocess_options()
substitutes the alias with a copy of the source option keeping only
the alias's long_name. So really the child proc will get the old
--negotiate-tip name but the child has an alias anyway.. works fine.

Good. v3 was using the old name when shelling out (just a nit), but
nicer to have the rename fully consistent.

Overall this patch LGTM! All my v3 issues were addressed.

The typo (plural vs singular 'tips') is fixed - thanks!

Same as in v3, this function will be refactored in a later patch, so
just doing the rename now keeps things reviewable - thanks!

This is nice! Addressed my concerns in v3 about the wrong message being
shown, and makes it clearer with an up-front check for the protocol
support.

Good - reusing the parse_transport_option() as suggested makes this a
smaller diff and consistent with 'serveroption' above.

As always, thanks for reviewing! Your comments on patch 3 in
particular led me to what would have been a rather annoying bug, so
thanks for calling out an improvement to the testcase that alerted me
to that issue.

I can totally see where the comments came from; they did seem logical
on the surface. I knew the changes were cherry-specific in a few
ways, but trying to figure out how to explain that and dig further
into the details to find a good angle (and try to make sure I wasn't
just missing something about how part of the logic could be shared)
took a bunch of additional time, so I'm happy to hear that others
consider it enlightening. That makes it time well spent.

This is a new patch in v4, and is in response to the COMMON (bit 2) vs
COMMON (bit 6) issue of v3.
Having a defined have_sent() API on the negotiator, and letting the
negotiator handle its own book-keeping is much nicer and safer.

I traced this through default.c's mark_common() to confirm this does
what we want.. sets the COMMON bit (bit 2) and propogates COMMON to
the ancestors correctly. Good!

I traced this too, to skipping.c's mark_common(), and it sets the COMMON
bit correctly.
This patch is a welcome addition and LGTM!

Great! Now we have a unified implementation that takes a string_list
and ouputs an oid_array, used for both restrict and include lists.
We pre-resolve so that fetch-pack gets the oid_array so the ref
resolution happens in the same layer for both.
Just one small issue I see - the function emits a warning for
"--negotiate-restrict" when we don't match a ref, even if this is
handling a --negotiate-include value. Perhaps we should pass the
option name in as a parameter?

Nice - this is much simpler since ref resolution has been hoisted up

Overall this version of the patch is much better IMO! Just that one
comment about the incorrect option name in the warning message.

Thanks - references the correct cross-referenced option I raised in v3.

One thing to mention: the "also used during push negotiation" sentence
is added here, and then I see in the next patch (patch 8) we're adding
another sentence "these values also influence negotiation during git
push" to this same block.
Perhaps consider dropping the additional 'push' sentence here (patch 7)
and let patch 8 add just its own sentence about push? Not too pressing.

Great! Now this test will catch failures to the reset-list behaviour
by using a different CLI option ref name than is in the config list.

Overall this patch addresses my comments from v3's review. Just the
minor issue with forward reference to 'git push' behaviour in the docs.

Is this paragraph stale? Didn't we rename the option in patch 2?

Thank you for going through the comments on v3 in detail. This is a nice
improvement overall.
The main thing flagged (the COMMON bit confusion) is resolved by adding
the new have_sent() API on the negotiator interface, which is much
clearer and cleaner. The hoisting of the ref resolution to the same
layer and reuse of add_negotiate_tips() is also done and appreciated!
I've left replies on each patch, with only a small number of easily
addressed comments.
Thanks,

* [RFC PATCH v5 0/3] push: add support for pushing to remote groups
From: Usman Akinyemi @ 2026-05-18 18:27 UTC (permalink / raw)
To: usmanakinyemi202, git; +Cc: christian.couder, gitster, me, phillip.wood123, ps
In-Reply-To: <20260503153402.1333220-4-usmanakinyemi202@gmail.com>
This RFC series adds support for `git push` to accept a remote group
name (as configured via `remotes.<name>` in config) in addition to a
single remote name, mirroring the behaviour that `git fetch` has
supported for some time.
A user with multiple remotes configured as a group can now do:
git push all-remotes
instead of pushing to each remote individually, in the same way that:
git fetch all-remotes
already works.
The series is split into three patches:
- Patch 1 fix sign-compare warnings in push_cas_option
- Patch 2 moves `get_remote_group`, `add_remote_or_group`, and the
`remote_group_data` struct out of builtin/fetch.c and into
remote.c/remote.h, making them part of the public remote API.
- Patch 2 extends builtin/push.c to use the newly public
`add_remote_or_group()` to resolve the repository argument as
either a single remote or a group, and pushes to each member of
the group in turn.
Changes in v6:
- fix docs formating

`get_remote_group`, `add_remote_or_group`, and the `remote_group_data`
struct are currently defined as static helpers inside builtin/fetch.c.
They implement generic remote group resolution that is not specific to
fetch — they parse `remotes.<name>` config entries and resolve a name
to either a list of group members or a single configured remote.
Move them to remote.c and declare them in remote.h so that other
builtins can use the same logic without duplication.
Useful for the next patch.

* [PATCH v6 3/3] push: support pushing to a remote group
From: Usman Akinyemi @ 2026-05-18 18:27 UTC (permalink / raw)
To: usmanakinyemi202, git; +Cc: christian.couder, gitster, me, phillip.wood123, ps
In-Reply-To: <20260518182721.155070-1-usmanakinyemi202@gmail.com>
`git fetch` accepts a remote group name (configured via `remotes.<name>`
in config) and fetches from each member remote. `git push` has no
equivalent — it only accepts a single remote name.
Teach `git push` to resolve its repository argument through
`add_remote_or_group()`, which was made public in the previous patch,
so that a user can push to all remotes in a group with:
git push <group>
When the argument resolves to a single remote, the behaviour is
identical to before. When it resolves to a group, each member remote
is pushed in sequence.
The group push path rebuilds the refspec list (`rs`) from scratch for
each member remote so that per-remote push mappings configured via
`remote.<name>.push` are resolved correctly against each specific
remote. Without this, refspec entries would accumulate across iterations
and each subsequent remote would receive a growing list of duplicated
entries.
Mirror detection (`remote->mirror`) is also evaluated per remote using
a copy of the flags, so that a mirror remote in the group cannot set
TRANSPORT_PUSH_FORCE on subsequent non-mirror remotes in the same group.

+Updates one or more branches, tags, or other references in one or more

The simplest way to push is `git push <remote> <branch>`.

+REMOTE GROUPS
+-------------
+
+A remote group is a named list of remotes configured via `remotes.<name>`
+in your git config:
+
+ $ git config remotes.all-remotes "r1 r2 r3"
+
+When a group name is given as the `<repository>` argument, the push is
+performed to each member remote in turn. The defining principle is:
+
+ git push <options> all-remotes <args>
+
+is exactly equivalent to:
+
+ git push <options> r1 <args>
+ git push <options> r2 <args>
+ ...
+ git push <options> rN <args>
+
+where `r1`, `r2`, ..., `rN` are the members of `all-remotes`. No special
+behaviour is added or removed — the group is purely a shorthand for
+running the same push command against each member remote individually.
+
+When pushing to a group of more than one remote, Git spawns a separate
+`git push` subprocess for each member remote in sequence. Each subprocess
+receives the same flags and refspecs as the original invocation. This
+means that per-remote push mappings configured via `remote.<name>.push`
+and mirror mode (`remote.<name>.mirror`) are evaluated independently for
+each remote, and a mirror remote in the group cannot affect the push
+behaviour of other non-mirror remotes in the same group.
+
+The `--atomic` option is not supported for group pushes, because atomicity
+can only be guaranteed within a single transport connection to a single
+remote. Git will refuse the invocation with an error if `--atomic` is
+combined with a group name.
+
+If any member remote fails whether due to a push rejection (e.g. a
+non-fast-forward update, a server-side hook refusing a ref) or a connection
+error (e.g. the repository does not exist, authentication fails, or the
+network is unreachable), Git reports the error and continues pushing to
+the remaining remotes in the group. The overall exit code is non-zero if
+any member push fails.
+
+This means the user is responsible for ensuring that the sequence of
+individual pushes makes sense. If `git push r1` would fail for a given
+set of options and arguments, then `git push all-remotes` will fail in
+the same way when it reaches `r1`. The group push does not do anything
+special to make a failing individual push succeed.

Thanks for your review, including a confirmation that I properly
responded to your earlier review. Soon, I'll send a new version with

* [PATCH v5 0/8] fetch: rework negotiation tip options
From: Derrick Stolee via GitGitGadget @ 2026-05-18 20:19 UTC (permalink / raw)
To: git; +Cc: gitster, ps, Matthew John Cheetham, Derrick Stolee
In-Reply-To: <pull.2085.v4.git.1778762495.gitgitgadget@gmail.com>
Fetch negotiation aims to find enough information from haves and wants such
that the server can be reasonably confident that it will send all necessary
objects and not too many "extra" objects that the client already has.
However, this can break down if there are too many references, since Git
truncates the list of haves based on a few factors (a 256 count limit or the
server sending an ACK at the right time).
We already have the --negotiation-tip feature to focus the set of references
that are used in negotiation, but I feel like this is designed backwards.
I'd rather that we have a way to say "this is an important set of refs, but
feel free to add more refs if needed" than "only use these refs for
negotiation".
Here's an example that demonstrates the problem. In an internal monorepo,
developers work off of the 'main' branch so there are thousands of user
branches that each add a few commits different from the 'main' branch.
However, there is also a long-lived 'release' branch. This branch has a
first-parent history that is parallel to 'main' and each of those commits is
a merge whose second parent is a commit from 'main' that had a successful CI
run. There are additional changes in the 'release' branch merge commits that
add some changelog data, so there is a nontrivial set of novel blob content
in that branch and not just a different set of commits.
The problem we had was that our georeplication system was regularly fetching
from the origin and trying to get all data from all reachable branches. When
the 'release' branch updated, the client would run out of haves before
advertising its copy of the 'release' branch, but it would still list the
new 'release' tip as a want. The server would then think that the client had
never fetched that branch before and would send all of the changelog data
from the whole history of the repo. (This led to a lot of downstream
problems; we mitigated by setting a refspec that stopped fetching the
'release' branch, but this is not ideal.)
What I'd like is a mechanism to say "always advertise the client's version
of 'main' and 'release' but also opportunistically include some user
branches".
Based on my understanding, the '--negotiation-tip' option is close but not
quite what I want. I could have the client only advertise 'release' and
'main' and never advertise any user branches. But then we'd download all
content from each user branch every time it updates. Perhaps this would
happen even with opportunistic inclusion of more haves, but I'd like to
explore this area more.
There's also an issue that the '--negotiation-tip' feature doesn't seem to
have a config key that enables it without CLI arguments. This is something
that we could consider independently.
This patch series adds a new '--negotiation-include' option that does what I
want: it makes sure that these references are included as 'have's during
negotiation. In order to help clarify the difference between this and
'--negotiation-tip', I first create a synonym called
'--negotiation-restrict'.
Both of these options get 'remote.*.negotiation(Include|Restrict)' config
options that enable their behavior by default.
During development, I had briefly considered only using config values, but
that required some strange changes to care about the remote name in the
transport layer. This was most different in the 'git push' integration. When
I discovered the '--negotiation-tip' feature during the process, that gave
me a clear pattern to follow with the addition of a config on top.
Updates in v2
=============
This version is a near-complete rewrite based on feedback around the names
of the previous option and config. The --negotiation-restrict option is new
and the ability to set it via config is also new.
I did try to be more careful around translatable error messages, too.
Updates in v3
=============
* --negotiation-tip is now an alias of --negotiation-restrict.
* More translatable strings use %s to isolate non-translatable options from
translatable words.
* The string_list named negotiation_tip is now renamed to
negotiation_restrict.
* The config options now allow an empty value to reset the list.
* The --negotiation-require option is now called --negotiation-include.
* Similarly, the config option is renamed and all code references.
* The included haves now mark their commits as COMMON so commits that they
can reach are not included in the negotiation walk if they are reached
from the restricted commits.
* The ref iterators are more careful about failing on bad references (ref
exists but object doesn't) and ignoring missing references (perhaps
config is erroneous?).
* When sending tips during push negotiation, use the --negotiation-restrict
option instead of -tip.
Updates in v4
=============
Thanks, Matthew, for the detailed review! There are some big changes in this
version.
* Expanded commit message to cite the commit that introduced the bug
(3f763ddf28).
* Renamed --negotiation-tip to --negotiation-restrict throughout docs/code
(including send-pack.c, transport-helper.c, builtin/pull.c). Added
OPT_ALIAS in git-pull.
* Switched config parsing to use parse_transport_option() helper. Removed
git push from docs (not implemented yet). Restructured --negotiate-only
validation flow.
* NEW Patch 5: Added have_sent() interface to negotiators, so included
haves can be de-duplicated properly by the negotiation algorithm.
* Replaced COMMON flag hack with negotiator->have_sent() calls. Moved
ref-pattern resolution into builtin/fetch.c (add_negotiation_tips()) so
fetch-pack receives pre-resolved oid_array instead of string_list. Added
test for --negotiation-tip ignoring missing refs. Added
duplicate-avoidance test for v0. Accepts commit hashes in addition to ref
names/globs.
* Use parse_transport_option() for config. Updated docs to mention commit
hashes. Removed git push from config docs. Fixed test to use correct
restrict/include combinations.
* In the last patch, add doc notes that remote config values also apply
during git push with push.negotiate, now that they are integrated by that
change.

* [PATCH v5 2/8] fetch: add --negotiation-restrict option
From: Derrick Stolee via GitGitGadget @ 2026-05-18 20:19 UTC (permalink / raw)
To: git; +Cc: gitster, ps, Matthew John Cheetham, Derrick Stolee,
Derrick Stolee
In-Reply-To: <pull.2085.v5.git.1779135575.gitgitgadget@gmail.com>
From: Derrick Stolee <stolee@gmail.com>
The --negotiation-tip option to 'git fetch' and 'git pull' allows users
to specify that they want to focus negotiation on a small set of
references. This is a _restriction_ on the negotiation set, helping to
focus the negotiation when the ref count is high. However, it doesn't
allow for the ability to opportunistically select references beyond that
list.
This subtle detail that this is a 'maximum set' and not a 'minimum set'
is not immediately clear from the option name. This makes it more
complicated to add a new option that provides the complementary behavior
of a minimum set.
For now, create a new synonym option, --negotiation-restrict, that
behaves identically to --negotiation-tip. Update the documentation to
make it clear that this new name is the preferred option, but we keep
the old name for compatibility. Mark --negotiation-tip as an alias of the
new, preferred option.
Update a few warning messages with the new option, but also make them
translatable with the option name inserted by formatting. At least one
of these messages will be reused later for a new option.

* [PATCH v5 3/8] transport: rename negotiation_tips
From: Derrick Stolee via GitGitGadget @ 2026-05-18 20:19 UTC (permalink / raw)
To: git; +Cc: gitster, ps, Matthew John Cheetham, Derrick Stolee,
Derrick Stolee
In-Reply-To: <pull.2085.v5.git.1779135575.gitgitgadget@gmail.com>
From: Derrick Stolee <stolee@gmail.com>
The previous change added the --negotiation-restrict synonym for the
--negotiation-tip option for 'git fetch'. In anticipation of adding a new
option that behaves similarly but with distinct changes to its behavior,
rename the internal representation of this data from 'negotiation_tips' to
'negotiation_restrict_tips'.
The 'tips' part is kept because this is an oid_array in the transport layer.
This requires the builtin to handle parsing refs into collections of oids so
the transport layer can handle this cleaner form of the data.
Also update the string_list used to store the inputs from command-line
options.

* [PATCH v5 4/8] remote: add remote.*.negotiationRestrict config
From: Derrick Stolee via GitGitGadget @ 2026-05-18 20:19 UTC (permalink / raw)
To: git; +Cc: gitster, ps, Matthew John Cheetham, Derrick Stolee,
Derrick Stolee
In-Reply-To: <pull.2085.v5.git.1779135575.gitgitgadget@gmail.com>
From: Derrick Stolee <stolee@gmail.com>
In a previous change, the --negotiation-restrict command-line option of 'git
fetch' was added as a synonym of --negotiation-tip. Both of these options
restrict the set of 'haves' the client can send as part of negotiation.
This was previously not available via a configuration option. Add a new
'remote.<name>.negotiationRestrict' multi-valued config option that updates
'git fetch <name>' to use these restrictions by default.
If the user provides even one --negotiation-restrict argument, then the
config is ignored.
An empty value resets the value list to allow ignoring earlier config
values, such as those that might be set in system or global config.

* [PATCH v5 5/8] negotiator: add have_sent() interface
From: Derrick Stolee via GitGitGadget @ 2026-05-18 20:19 UTC (permalink / raw)
To: git; +Cc: gitster, ps, Matthew John Cheetham, Derrick Stolee,
Derrick Stolee
In-Reply-To: <pull.2085.v5.git.1779135575.gitgitgadget@gmail.com>
From: Derrick Stolee <stolee@gmail.com>
In a future change, we will introduce a capability to choose specific commit
OIDs as 'have's in fetch negotiation, with the ability to have the
negotiator choose more 'have's to increase coverage beyond that required
core set. The negotiator works to avoid emitting 'have's that can reach each
other, but that logic is hidden beneath the negotiator's iterator function
pointer ('next'). We need a way to communicate to the negotiator that we
have picked a 'have' so it could incorporate that into its logic.
Add a have_sent() method to the fetch_negotiator interface. This is the
signal that allows the negotiator to track the commit as already shown and
can perform the proper bookkeeping to avoid emitting those objects or
anything they can reach.
For our non-trivial negotiators, it is sufficient to mark these commits as
common, so the implementation is quite simple. This logic will be exercised
in the next change.

* [PATCH v5 6/8] fetch: add --negotiation-include option for negotiation
From: Derrick Stolee via GitGitGadget @ 2026-05-18 20:19 UTC (permalink / raw)
To: git; +Cc: gitster, ps, Matthew John Cheetham, Derrick Stolee,
Derrick Stolee
In-Reply-To: <pull.2085.v5.git.1779135575.gitgitgadget@gmail.com>
From: Derrick Stolee <stolee@gmail.com>
Add a new --negotiation-include option to 'git fetch', which ensures
that certain ref tips are always sent as 'have' lines during fetch
negotiation, regardless of what the negotiation algorithm selects.
This is useful when the repository has a large number of references, so
the normal negotiation algorithm truncates the list. This is especially
important in repositories with long parallel commit histories. For
example, a repo could have a 'dev' branch for development and a
'release' branch for released versions. If the 'dev' branch isn't
selected for negotiation, then it's not a big deal because there are
many in-progress development branches with a shared history. However, if
'release' is not selected for negotiation, then the server may think
that this is the first time the client has asked for that reference,
causing a full download of its parallel commit history (and any extra
data that may be unique to that branch). This is based on a real example
where certain fetches would grow to 60+ GB when a release branch
updated.
This option is a complement to --negotiation-restrict, which reduces the
negotiation ref set to a specific list. In the earlier example, using
--negotiation-restrict to focus the negotiation to 'dev' and 'release'
would avoid those problematic downloads, but would still not allow
advertising potentially-relevant user branches. In this way, the
'include' version solves the problem I mention while allowing
negotiation to pick other references opportunistically. The two options
can also be combined to allow the best of both worlds.
The argument may be an exact ref name or a glob pattern. Non-existent
refs are silently ignored. This behavior is also updated in the ref matching
logic for the related --negotiation-restrict option to match.
The implementation outputs the requested objects as haves before the
negotiator performs its own algorithm to choose the next haves. Use the new
have_sent() interface to signal these have commits were sent before engaging
with the negotiator's next() iterator.
Also add --negotiation-include to 'git pull' passthrough options.
