remote.c: introduce a way to have different remotes for fetch/push
Currently, do_push() in push.c calls remote_get(), which gets the
configured remote for fetching and pushing. Replace this call with a
call to pushremote_get() instead, a new function that will return the
remote configured specifically for pushing. This function tries to
work with the string pushremote_name, before falling back to the
codepath of remote_get(). This patch has no visible impact, but
serves to enable future patches to introduce configuration variables
to set pushremote_name. For example, you can now do the following in
handle_config():
if (!strcmp(key, "remote.pushdefault"))
git_config_string(&pushremote_name, key, value);
Then, pushes will automatically go to the remote specified by
remote.pushdefault.

fetch: add a --prune-tags option and fetch.pruneTags config
Add a --prune-tags option to git-fetch, along with fetch.pruneTags
config option and a -P shorthand (-p is --prune). This allows for
doing any of:
git fetch -p -P
git fetch --prune --prune-tags
git fetch -p -P origin
git fetch --prune --prune-tags origin
Or simply:
git config fetch.prune true &&
git config fetch.pruneTags true &&
git fetch
Instead of the much more verbose:
git fetch --prune origin 'refs/tags/*:refs/tags/*' '+refs/heads/*:refs/remotes/origin/*'
Before this feature it was painful to support the use-case of pulling
from a repo which is having both its branches *and* tags deleted
regularly, and have our local references to reflect upstream.
At work we create deployment tags in the repo for each rollout, and
there's *lots* of those, so they're archived within weeks for
performance reasons.
Without this change it's hard to centrally configure such repos in
/etc/gitconfig (on servers that are only used for working with
them). You need to set fetch.prune=true globally, and then for each
repo:
git -C {} config --replace-all remote.origin.fetch "refs/tags/*:refs/tags/*" "^\+*refs/tags/\*:refs/tags/\*$"
Now I can simply set fetch.pruneTags=true in /etc/gitconfig as well,
and users running "git pull" will automatically get the pruning
semantics I want.
Even though "git remote" has corresponding "prune" and "update
--prune" subcommands I'm intentionally not adding a corresponding
prune-tags or "update --prune --prune-tags" mode to that command.
It's advertised (as noted in my recent "git remote doc: correct
dangerous lies about what prune does") as only modifying remote
tracking references, whereas any --prune-tags option is always going
to modify what from the user's perspective is a local copy of the tag,
since there's no such thing as a remote tracking tag.
Ideally add_prune_tags_to_fetch_refspec() would be something that
would use ALLOC_GROW() to grow the 'fetch` member of the 'remote'
struct. Instead I'm realloc-ing remote->fetch and adding the
tag_refspec to the end.
The reason is that parse_{fetch,push}_refspec which allocate the
refspec (ultimately remote->fetch) struct are called many places that
don't have access to a 'remote' struct. It would be hard to change all
their callsites to be amenable to carry around the bookkeeping
variables required for dynamic allocation.
All the other callers of the API first incrementally construct the
string version of the refspec in remote->fetch_refspec via
add_fetch_refspec(), before finally calling parse_fetch_refspec() via
some variation of remote_get().
It's less of a pain to deal with the one special case that needs to
modify already constructed refspecs than to chase down and change all
the other callsites. The API I'm adding is intentionally not
generalized because if we add more of these we'd probably want to
re-visit how this is done.

fetch: add a --prune-tags option and fetch.pruneTags config
Add a --prune-tags option to git-fetch, along with fetch.pruneTags
config option and a -P shorthand (-p is --prune). This allows for
doing any of:
git fetch -p -P
git fetch --prune --prune-tags
git fetch -p -P origin
git fetch --prune --prune-tags origin
Or simply:
git config fetch.prune true &&
git config fetch.pruneTags true &&
git fetch
Instead of the much more verbose:
git fetch --prune origin 'refs/tags/*:refs/tags/*' '+refs/heads/*:refs/remotes/origin/*'
Before this feature it was painful to support the use-case of pulling
from a repo which is having both its branches *and* tags deleted
regularly, and have our local references to reflect upstream.
At work we create deployment tags in the repo for each rollout, and
there's *lots* of those, so they're archived within weeks for
performance reasons.
Without this change it's hard to centrally configure such repos in
/etc/gitconfig (on servers that are only used for working with
them). You need to set fetch.prune=true globally, and then for each
repo:
git -C {} config --replace-all remote.origin.fetch "refs/tags/*:refs/tags/*" "^\+*refs/tags/\*:refs/tags/\*$"
Now I can simply set fetch.pruneTags=true in /etc/gitconfig as well,
and users running "git pull" will automatically get the pruning
semantics I want.
Even though "git remote" has corresponding "prune" and "update
--prune" subcommands I'm intentionally not adding a corresponding
prune-tags or "update --prune --prune-tags" mode to that command.
It's advertised (as noted in my recent "git remote doc: correct
dangerous lies about what prune does") as only modifying remote
tracking references, whereas any --prune-tags option is always going
to modify what from the user's perspective is a local copy of the tag,
since there's no such thing as a remote tracking tag.
Ideally add_prune_tags_to_fetch_refspec() would be something that
would use ALLOC_GROW() to grow the 'fetch` member of the 'remote'
struct. Instead I'm realloc-ing remote->fetch and adding the
tag_refspec to the end.
The reason is that parse_{fetch,push}_refspec which allocate the
refspec (ultimately remote->fetch) struct are called many places that
don't have access to a 'remote' struct. It would be hard to change all
their callsites to be amenable to carry around the bookkeeping
variables required for dynamic allocation.
All the other callers of the API first incrementally construct the
string version of the refspec in remote->fetch_refspec via
add_fetch_refspec(), before finally calling parse_fetch_refspec() via
some variation of remote_get().
It's less of a pain to deal with the one special case that needs to
modify already constructed refspecs than to chase down and change all
the other callsites. The API I'm adding is intentionally not
generalized because if we add more of these we'd probably want to
re-visit how this is done.

fetch config" (87po6ahx87.fsf@evledraar.gmail.com;

remote.c: Fix overtight refspec validation
We tightened the refspec validation code in an earlier commit ef00d15
(Tighten refspec processing, 2008-03-17) per my suggestion, but the
suggestion was misguided to begin with and it broke this usage:
$ git push origin HEAD~12:master
The syntax of push refspecs and fetch refspecs are similar in that they
are both colon separated LHS and RHS (possibly prefixed with a + to
force), but the similarity ends there. For example, LHS in a push refspec
can be anything that evaluates to a valid object name at runtime (except
when colon and RHS is missing, or it is a glob), while it must be a
valid-looking refname in a fetch refspec. To validate them correctly, the
caller needs to be able to say which kind of refspecs they are. It is
unreasonable to keep a single interface that cannot tell which kind it is
dealing with, and ask it to behave sensibly.
This commit separates the parsing of the two into different functions, and
clarifies the code to implement the parsing proper (i.e. splitting into
two parts, making sure both sides are wildcard or neither side is).
This happens to also allow pushing a commit named with the esoteric "look
for that string" syntax:

caller needs to be able to say which kind of refspecs they are. It is
unreasonable to keep a single interface that cannot tell which kind it is
dealing with, and ask it to behave sensibly.

clarifies the code to implement the parsing proper (i.e. splitting into
two parts, making sure both sides are wildcard or neither side is).

remote.c: Fix overtight refspec validation
We tightened the refspec validation code in an earlier commit ef00d15
(Tighten refspec processing, 2008-03-17) per my suggestion, but the
suggestion was misguided to begin with and it broke this usage:
$ git push origin HEAD~12:master
The syntax of push refspecs and fetch refspecs are similar in that they
are both colon separated LHS and RHS (possibly prefixed with a + to
force), but the similarity ends there. For example, LHS in a push refspec
can be anything that evaluates to a valid object name at runtime (except
when colon and RHS is missing, or it is a glob), while it must be a
valid-looking refname in a fetch refspec. To validate them correctly, the
caller needs to be able to say which kind of refspecs they are. It is

(Tighten refspec processing, 2008-03-17) per my suggestion, but the
suggestion was misguided to begin with and it broke this usage:
$ git push origin HEAD~12:master
The syntax of push refspecs and fetch refspecs are similar in that they
are both colon separated LHS and RHS (possibly prefixed with a + to
force), but the similarity ends there. For example, LHS in a push refspec
can be anything that evaluates to a valid object name at runtime (except
when colon and RHS is missing, or it is a glob), while it must be a
valid-looking refname in a fetch refspec. To validate them correctly, the
caller needs to be able to say which kind of refspecs they are. It is
unreasonable to keep a single interface that cannot tell which kind it is
dealing with, and ask it to behave sensibly.
This commit separates the parsing of the two into different functions, and
clarifies the code to implement the parsing proper (i.e. splitting into
two parts, making sure both sides are wildcard or neither side is).
This happens to also allow pushing a commit named with the esoteric "look
for that string" syntax:
$ git push ../test.git ':/remote.c: Fix overtight refspec:master'

Give error when no remote is configured
When there's no explicitly-named remote, we use the remote specified
for the current branch, which in turn defaults to "origin". But it
this case should require the remote to actually be configured, and not
fall back to the path "origin".
Possibly, the config file's "remote = something" should require the
something to be a configured remote instead of a bare repository URL,
but we actually test with a bare repository URL.
In fetch, we were giving the sensible error message when coming up
with a URL failed, but this wasn't actually reachable, so move that
error up and use it when appropriate.
In push, we need a new error message, because the old one (formerly
unreachable without a lot of help) used the repo name, which was NULL.

remote.c: introduce a way to have different remotes for fetch/push
Currently, do_push() in push.c calls remote_get(), which gets the
configured remote for fetching and pushing. Replace this call with a
call to pushremote_get() instead, a new function that will return the
remote configured specifically for pushing. This function tries to
work with the string pushremote_name, before falling back to the
codepath of remote_get(). This patch has no visible impact, but
serves to enable future patches to introduce configuration variables
to set pushremote_name. For example, you can now do the following in
handle_config():
if (!strcmp(key, "remote.pushdefault"))
git_config_string(&pushremote_name, key, value);
Then, pushes will automatically go to the remote specified by
remote.pushdefault.

push: use remote.$name.push as a refmap
Since f2690487 (fetch: opportunistically update tracking refs,
2013-05-11), we stopped taking a non-storing refspec given on the
command line of "git fetch" literally, and instead started mapping
it via remote.$name.fetch refspecs. This allows
$ git fetch origin master
from the 'origin' repository, which is configured with
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
to update refs/remotes/origin/master with the result, as if the
command line were
$ git fetch origin +master:refs/remotes/origin/master
to reduce surprises and improve usability. Before that change, a
refspec on the command line without a colon was only to fetch the
history and leave the result in FETCH_HEAD, without updating the
remote-tracking branches.
When you are simulating a fetch from you by your mothership with a
push by you into your mothership, instead of having:
[remote "satellite"]
fetch = +refs/heads/*:refs/remotes/satellite/*
on the mothership repository and running:
mothership$ git fetch satellite
you would have:
[remote "mothership"]
push = +refs/heads/*:refs/remotes/satellite/*
on your satellite machine, and run:
satellite$ git push mothership
Because we so far did not make the corresponding change to the push
side, this command:
satellite$ git push mothership master
does _not_ allow you on the satellite to only push 'master' out but
still to the usual destination (i.e. refs/remotes/satellite/master).
Implement the logic to map an unqualified refspec given on the
command line via the remote.$name.push refspec. This will bring a
bit more symmetry between "fetch" and "push".

sha1_name: convert get_sha1* to get_oid*
Now that all the callers of get_sha1 directly or indirectly use struct
object_id, rename the functions starting with get_sha1 to start with
get_oid. Convert the internals in sha1_name.c to use struct object_id
as well, and eliminate explicit length checks where possible. Convert a
use of 40 in get_oid_basic to GIT_SHA1_HEXSZ.
Outside of sha1_name.c and cache.h, this transition was made with the
following semantic patch:

push: allow unqualified dest refspecs to DWIM
Previously, a push like:
git push remote src:dst
would go through the following steps:
1. check for an unambiguous 'dst' on the remote; if it
exists, then push to that ref
2. otherwise, check if 'dst' begins with 'refs/'; if it
does, create a new ref
3. otherwise, complain because we don't know where in the
refs hierarchy to put 'dst'
However, in some cases, we can guess about the ref type of
'dst' based on the ref type of 'src'. Specifically, before
complaining we now check:
2.5. if 'src' resolves to a ref starting with refs/heads
or refs/tags, then prepend that to 'dst'
So now this creates a new branch on the remote, whereas it
previously failed with an error message:
git push master:newbranch
Note that, by design, we limit this DWIM behavior only to
source refs which resolve exactly (including symrefs which
resolve to existing refs). We still complain on a partial
destination refspec if the source is a raw sha1, or a ref
expression such as 'master~10'.

clean up error conventions of remote.c:match_explicit
match_explicit is called for each push refspec to try to
fully resolve the source and destination sides of the
refspec. Currently, we look at each refspec and report
errors on both the source and the dest side before aborting.
It makes sense to report errors for each refspec, since an
error in one is independent of an error in the other.
However, reporting errors on the 'dst' side of a refspec if
there has been an error on the 'src' side does not
necessarily make sense, since the interpretation of the
'dst' side depends on the 'src' side (for example, when
creating a new unqualified remote ref, we use the same type
as the src ref).
This patch lets match_explicit return early when the src
side of the refspec is bogus. We still look at all of the
refspecs before aborting the push, though.
At the same time, we clean up the call signature, which
previously took an extra "errs" flag. This was pointless, as
we didn't act on that flag, but rather just passed it back
to the caller. Instead, we now use the more traditional
"return -1" to signal an error, and the caller aggregates
the error count.
This change fixes two bugs, as well:
- the early return avoids a segfault when passing a NULL
matched_src to guess_ref()
- the check for multiple sources pointing to a single dest
aborted if the "err" flag was set. Presumably the intent
was not to bother with the check if we had no
matched_src. However, since the err flag was passed in
from the caller, we might abort the check just because a
previous refspec had a problem, which doesn't make
sense.
In practice, this didn't matter, since due to the error
flag we end up aborting the push anyway.

push: don't guess at qualifying remote refs on deletion
When we try to push a ref and the right-hand side of the
refspec does not find a match, we try to create it. If it is
not fully qualified, we try to guess where it would go in
the refs hierarchy based on the left-hand source side. If
the source side is not a ref, then we give up and give a
long explanatory message.
For deletions, however, this doesn't make any sense. We
would never want to create on the remote side, and if an
unqualified ref can't be matched, it is simply an error. The
current code handles this already because the left-hand side
is empty, and therefore does not give us a hint as to where
the right-hand side should go, and we properly error out.
Unfortunately, the error message is the long "we tried to
qualify this, but the source side didn't let us guess"
message, which is quite confusing.
Instead, we can just be more succinct and say "we can't
delete this because we couldn't find it". So before:
$ git push origin :bogus
error: unable to push to unqualified destination: bogus
The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.
error: failed to push some refs to '$URL'
and now:
$ git push origin :bogus
error: unable to delete 'bogus': remote ref does not exist
error: failed to push some refs to '$URL'
It is tempting to also catch a fully-qualified ref like
"refs/heads/bogus" and generate the same error message.
However, that currently does not error out at all, and
instead gets sent to the remote side, which typically
generates a warning:
$ git push origin:refs/heads/bogus
remote: warning: Deleting a non-existent ref.
To $URL
- [deleted] bogus
While it would be nice to catch this error early, a
client-side error would mean aborting the push entirely and
changing push's exit code. For example, right now you can
do:
$ git push origin refs/heads/foo refs/heads/bar
and end up in a state where "foo" and "bar" are deleted,
whether both of them currently exist or not (and see an
error only if we actually failed to contact the server).
Generating an error would cause a regression for this use
case.

push: allow unqualified dest refspecs to DWIM
Previously, a push like:
git push remote src:dst
would go through the following steps:
1. check for an unambiguous 'dst' on the remote; if it
exists, then push to that ref
2. otherwise, check if 'dst' begins with 'refs/'; if it
does, create a new ref
3. otherwise, complain because we don't know where in the
refs hierarchy to put 'dst'
However, in some cases, we can guess about the ref type of
'dst' based on the ref type of 'src'. Specifically, before
complaining we now check:
2.5. if 'src' resolves to a ref starting with refs/heads
or refs/tags, then prepend that to 'dst'
So now this creates a new branch on the remote, whereas it
previously failed with an error message:
git push master:newbranch
Note that, by design, we limit this DWIM behavior only to
source refs which resolve exactly (including symrefs which
resolve to existing refs). We still complain on a partial
destination refspec if the source is a raw sha1, or a ref
expression such as 'master~10'.

clean up error conventions of remote.c:match_explicit
match_explicit is called for each push refspec to try to
fully resolve the source and destination sides of the
refspec. Currently, we look at each refspec and report
errors on both the source and the dest side before aborting.
It makes sense to report errors for each refspec, since an
error in one is independent of an error in the other.
However, reporting errors on the 'dst' side of a refspec if
there has been an error on the 'src' side does not
necessarily make sense, since the interpretation of the
'dst' side depends on the 'src' side (for example, when
creating a new unqualified remote ref, we use the same type
as the src ref).
This patch lets match_explicit return early when the src
side of the refspec is bogus. We still look at all of the
refspecs before aborting the push, though.
At the same time, we clean up the call signature, which
previously took an extra "errs" flag. This was pointless, as
we didn't act on that flag, but rather just passed it back
to the caller. Instead, we now use the more traditional
"return -1" to signal an error, and the caller aggregates
the error count.
This change fixes two bugs, as well:
- the early return avoids a segfault when passing a NULL
matched_src to guess_ref()
- the check for multiple sources pointing to a single dest
aborted if the "err" flag was set. Presumably the intent
was not to bother with the check if we had no
matched_src. However, since the err flag was passed in
from the caller, we might abort the check just because a
previous refspec had a problem, which doesn't make
sense.
In practice, this didn't matter, since due to the error
flag we end up aborting the push anyway.

Convert lookup_commit* to struct object_id
Convert lookup_commit, lookup_commit_or_die,
lookup_commit_reference, and lookup_commit_reference_gently to take
struct object_id arguments.
Introduce a temporary in parse_object buffer in order to convert this
function. This is required since in order to convert parse_object and
parse_object_buffer, lookup_commit_reference_gently and
lookup_commit_or_die would need to be converted. Not introducing a
temporary would therefore require that lookup_commit_or_die take a
struct object_id *, but lookup_commit would take unsigned char *,
leaving a confusing and hard-to-use interface.
parse_object_buffer will lose this temporary in a later patch.

Convert lookup_commit* to struct object_id
Convert lookup_commit, lookup_commit_or_die,
lookup_commit_reference, and lookup_commit_reference_gently to take
struct object_id arguments.
Introduce a temporary in parse_object buffer in order to convert this
function. This is required since in order to convert parse_object and
parse_object_buffer, lookup_commit_reference_gently and
lookup_commit_or_die would need to be converted. Not introducing a
temporary would therefore require that lookup_commit_or_die take a
struct object_id *, but lookup_commit would take unsigned char *,
leaving a confusing and hard-to-use interface.
parse_object_buffer will lose this temporary in a later patch.

remote.c: avoid O(m*n) behavior in match_push_refs
When pushing using a matching refspec or a pattern refspec, each ref
in the local repository must be paired with a ref advertised by the
remote server. This is accomplished by using the refspec to transform
the name of the local ref into the name it should have in the remote
repository, and then performing a linear search through the list of
remote refs to see if the remote ref was advertised by the remote
system.
Each of these lookups has O(n) complexity and makes match_push_refs()
be an O(m*n) operation, where m is the number of local refs and n is
the number of remote refs. If there are many refs 100,000+, then this
ref matching can take a significant amount of time. Let's prepare an
index of the remote refs to allow searching in O(log n) time and
reduce the complexity of match_push_refs() to O(m log n).
We prepare the index lazily so that it is only created when necessary.
So, there should be no impact when _not_ using a matching or pattern
refspec, i.e. when pushing using only explicit refspecs.
Dry-run push of a repository with 121,913 local and remote refs:
before after
real 1m40.582s 0m0.804s
user 1m39.914s 0m0.515s
sys 0m0.125s 0m0.106s
The creation of the index has overhead. So, if there are very few
local refs, then it could take longer to create the index than it
would have taken to just perform n linear lookups into the remote
ref space. Using the index should provide some improvement when
the number of local refs is roughly greater than the log of the
number of remote refs (i.e. m >= log n). The pathological case is
when there is a single local ref and very many remote refs.
Dry-run push of a repository with 121,913 remote refs and a single
local ref:
before after
real 0m0.525s 0m0.566s
user 0m0.243s 0m0.279s
sys 0m0.075s 0m0.099s
Using an index takes 41 ms longer, or roughly 7.8% longer.
Jeff King measured a no-op push of a single ref into a remote repo
with 370,000 refs:
before after
real 0m1.087s 0m1.156s
user 0m1.344s 0m1.412s
sys 0m0.288s 0m0.284s
Using an index takes 69 ms longer, or roughly 6.3% longer.
None of the measurements above required transferring any objects to
the remote repository. If the push required transferring objects and
updating the refs in the remote repository, the impact of preparing
the search index would be even smaller.
A similar operation is performed in the reverse direction when pruning
using a matching or pattern refspec. Let's avoid O(m*n) behavior in
the same way by lazily preparing an index on the local refs.

remote.c: avoid O(m*n) behavior in match_push_refs
When pushing using a matching refspec or a pattern refspec, each ref
in the local repository must be paired with a ref advertised by the
remote server. This is accomplished by using the refspec to transform
the name of the local ref into the name it should have in the remote
repository, and then performing a linear search through the list of
remote refs to see if the remote ref was advertised by the remote
system.
Each of these lookups has O(n) complexity and makes match_push_refs()
be an O(m*n) operation, where m is the number of local refs and n is
the number of remote refs. If there are many refs 100,000+, then this
ref matching can take a significant amount of time. Let's prepare an
index of the remote refs to allow searching in O(log n) time and
reduce the complexity of match_push_refs() to O(m log n).
We prepare the index lazily so that it is only created when necessary.
So, there should be no impact when _not_ using a matching or pattern
refspec, i.e. when pushing using only explicit refspecs.

real 1m40.582s 0m0.804s
user 1m39.914s 0m0.515s
sys 0m0.125s 0m0.106s
The creation of the index has overhead. So, if there are very few
local refs, then it could take longer to create the index than it
would have taken to just perform n linear lookups into the remote
ref space. Using the index should provide some improvement when
the number of local refs is roughly greater than the log of the
number of remote refs (i.e. m >= log n). The pathological case is
when there is a single local ref and very many remote refs.

push: fix "refs/tags/ hierarchy cannot be updated without --force"
When pushing to update a branch with a commit that is not a
descendant of the commit at the tip, a wrong message "already
exists" was given, instead of the correct "non-fast-forward", if we
do not have the object sitting in the destination repository at the
tip of the ref we are updating.
The primary cause of the bug is that the check in a new helper
function is_forwardable() assumed both old and new objects are
available and can be checked, which is not always the case.
The way the caller uses the result of this function is also wrong.
If the helper says "we do not want to let this push go through", the
caller unconditionally translates it into "we blocked it because the
destination already exists", which is not true at all in this case.
Fix this by doing these three things:
* Remove unnecessary not_forwardable from "struct ref"; it is only
used inside set_ref_status_for_push();
* Make "refs/tags/" the only hierarchy that cannot be replaced
without --force;
* Remove the misguided attempt to force that everything that
updates an existing ref has to be a commit outside "refs/tags/"
hierarchy.
The policy last one tried to implement may later be resurrected and
extended to ensure fast-forwardness (defined as "not losing
objects", extending from the traditional "not losing commits from
the resulting history") when objects that are not commit are
involved (e.g. an annotated tag in hierarchies outside refs/tags),
but such a logic belongs to "is this a fast-forward?" check that is
done by ref_newer(); is_forwardable(), which is now removed, was not
the right place to do so.

Convert lookup_commit* to struct object_id
Convert lookup_commit, lookup_commit_or_die,
lookup_commit_reference, and lookup_commit_reference_gently to take
struct object_id arguments.
Introduce a temporary in parse_object buffer in order to convert this
function. This is required since in order to convert parse_object and
parse_object_buffer, lookup_commit_reference_gently and
lookup_commit_or_die would need to be converted. Not introducing a
temporary would therefore require that lookup_commit_or_die take a
struct object_id *, but lookup_commit would take unsigned char *,
leaving a confusing and hard-to-use interface.
parse_object_buffer will lose this temporary in a later patch.

checkout: report upstream correctly even with loosely defined branch.*.merge
When checking out a branch that is set to build on top of another
branch (often, a remote-tracking branch), "git checkout" reports how
your work relates to the other branch, e.g.
Your branch is behind 'origin/master', and can be fast-forwarded.
Back when this feature was introduced, this was only done for
branches that build on remote-tracking branches, but 5e6e2b48 (Make
local branches behave like remote branches when --tracked,
2009-04-01) added support to give the same report for branches that
build on other local branches (i.e. branches whose branch.*.remote
variables are set to '.'). Unlike the support for the branches
building on remote-tracking branches, however, this did not take
into account the fact that branch.*.merge configuration is allowed
to record a shortened branch name.
When branch.*.merge is set to 'master' (not 'refs/heads/master'),
i.e. "my branch builds on the local 'master' branch", this caused
"git checkout" to report:
Your branch is based on 'master', but the upstream is gone.
The upstream is our repository and is definitely not gone, so this
output is nonsense.
The fix is fairly obvious; just like the branch name is DWIMed when
"git pull" merges from the 'master' branch without complaint on such
a branch, the name of the branch the current branch builds upon
needs to be DWIMed the same way.

remote.c: drop "remote" pointer from "struct branch"
When we create each branch struct, we fill in the
"remote_name" field from the config, and then fill in the
actual "remote" field (with a "struct remote") based on that
name. However, it turns out that nobody really cares about
the latter field. The only two sites that access it at all
are:
1. git-merge, which uses it to notice when the branch does
not have a remote defined. But we can easily replace this
with looking at remote_name instead.
2. remote.c itself, when setting up the @{upstream} merge
config. But we don't need to save the "remote" in the
"struct branch" for that; we can just look it up for
the duration of the operation.
So there is no need to have both fields; they are redundant
with each other (the struct remote contains the name, or you
can look up the struct from the name). It would be nice to
simplify this, especially as we are going to add matching
pushremote config in a future patch (and it would be nice to
keep them consistent).
So which one do we keep and which one do we get rid of?
If we had a lot of callers accessing the struct, it would be
more efficient to keep it (since you have to do a lookup to
go from the name to the struct, but not vice versa). But we
don't have a lot of callers; we have exactly one, so
efficiency doesn't matter. We can decide this based on
simplicity and readability.
And the meaning of the struct value is somewhat unclear. Is
it always the remote matching remote_name? If remote_name is
NULL (i.e., no per-branch config), does the struct fall back
to the "origin" remote, or is it also NULL? These questions
will get even more tricky with pushremotes, whose fallback
behavior is more complicated. So let's just store the name,
which pretty clearly represents the branch.*.remote config.
Any lookup or fallback behavior can then be implemented in
helper functions.

remote.c: refactor setup of branch->merge list
When we call branch_get() to lookup or create a "struct
branch", we make sure the "merge" field is filled in so that
callers can access it. But the conditions under which we do
so are a little confusing, and can lead to two funny
situations:
1. If there's no branch.*.remote config, we cannot provide
branch->merge (because it is really just an application
of branch.*.merge to our remote's refspecs). But
branch->merge_nr may be non-zero, leading callers to be
believe they can access branch->merge (e.g., in
branch_merge_matches and elsewhere).
It doesn't look like this can cause a segfault in
practice, as most code paths dealing with merge config
will bail early if there is no remote defined. But it's
a bit of a dangerous construct.
We can fix this by setting merge_nr to "0" explicitly
when we realize that we have no merge config. Note that
merge_nr also counts the "merge_name" fields (which we
_do_ have; that's how merge_nr got incremented), so we
will "lose" access to them, in the sense that we forget
how many we had. But no callers actually care; we use
merge_name only while iteratively reading the config,
and then convert it to the final "merge" form the first
time somebody calls branch_get().
2. We set up the "merge" field every time branch_get is
called, even if it has already been done. This leaks
memory.
It's not a big deal in practice, since most code paths
will access only one branch, or perhaps each branch
only one time. But if you want to be pathological, you
can leak arbitrary memory with:
yes @{upstream} | head -1000 | git rev-list --stdin
We can fix this by skipping setup when branch->merge is
already non-NULL.
In addition to those two fixes, this patch pushes the "do we
need to setup merge?" logic down into set_merge, where it is
a bit easier to follow.

remote.c: drop "remote" pointer from "struct branch"
When we create each branch struct, we fill in the
"remote_name" field from the config, and then fill in the
actual "remote" field (with a "struct remote") based on that
name. However, it turns out that nobody really cares about
the latter field. The only two sites that access it at all
are:
1. git-merge, which uses it to notice when the branch does
not have a remote defined. But we can easily replace this
with looking at remote_name instead.
2. remote.c itself, when setting up the @{upstream} merge
config. But we don't need to save the "remote" in the
"struct branch" for that; we can just look it up for
the duration of the operation.
So there is no need to have both fields; they are redundant
with each other (the struct remote contains the name, or you
can look up the struct from the name). It would be nice to
simplify this, especially as we are going to add matching
pushremote config in a future patch (and it would be nice to
keep them consistent).
So which one do we keep and which one do we get rid of?
If we had a lot of callers accessing the struct, it would be
more efficient to keep it (since you have to do a lookup to
go from the name to the struct, but not vice versa). But we
don't have a lot of callers; we have exactly one, so
efficiency doesn't matter. We can decide this based on
simplicity and readability.
And the meaning of the struct value is somewhat unclear. Is
it always the remote matching remote_name? If remote_name is
NULL (i.e., no per-branch config), does the struct fall back
to the "origin" remote, or is it also NULL? These questions
will get even more tricky with pushremotes, whose fallback
behavior is more complicated. So let's just store the name,
which pretty clearly represents the branch.*.remote config.
Any lookup or fallback behavior can then be implemented in
helper functions.

checkout: report upstream correctly even with loosely defined branch.*.merge
When checking out a branch that is set to build on top of another
branch (often, a remote-tracking branch), "git checkout" reports how
your work relates to the other branch, e.g.
Your branch is behind 'origin/master', and can be fast-forwarded.
Back when this feature was introduced, this was only done for
branches that build on remote-tracking branches, but 5e6e2b48 (Make
local branches behave like remote branches when --tracked,
2009-04-01) added support to give the same report for branches that
build on other local branches (i.e. branches whose branch.*.remote
variables are set to '.'). Unlike the support for the branches
building on remote-tracking branches, however, this did not take
into account the fact that branch.*.merge configuration is allowed
to record a shortened branch name.
When branch.*.merge is set to 'master' (not 'refs/heads/master'),
i.e. "my branch builds on the local 'master' branch", this caused
"git checkout" to report:
Your branch is based on 'master', but the upstream is gone.
The upstream is our repository and is definitely not gone, so this
output is nonsense.
The fix is fairly obvious; just like the branch name is DWIMed when
"git pull" merges from the 'master' branch without complaint on such
a branch, the name of the branch the current branch builds upon
needs to be DWIMed the same way.

remote.c: refactor setup of branch->merge list
When we call branch_get() to lookup or create a "struct
branch", we make sure the "merge" field is filled in so that
callers can access it. But the conditions under which we do
so are a little confusing, and can lead to two funny
situations:
1. If there's no branch.*.remote config, we cannot provide
branch->merge (because it is really just an application
of branch.*.merge to our remote's refspecs). But
branch->merge_nr may be non-zero, leading callers to be
believe they can access branch->merge (e.g., in
branch_merge_matches and elsewhere).
It doesn't look like this can cause a segfault in
practice, as most code paths dealing with merge config
will bail early if there is no remote defined. But it's
a bit of a dangerous construct.
We can fix this by setting merge_nr to "0" explicitly
when we realize that we have no merge config. Note that
merge_nr also counts the "merge_name" fields (which we
_do_ have; that's how merge_nr got incremented), so we
will "lose" access to them, in the sense that we forget
how many we had. But no callers actually care; we use
merge_name only while iteratively reading the config,
and then convert it to the final "merge" form the first
time somebody calls branch_get().
2. We set up the "merge" field every time branch_get is
called, even if it has already been done. This leaks
memory.
It's not a big deal in practice, since most code paths
will access only one branch, or perhaps each branch
only one time. But if you want to be pathological, you
can leak arbitrary memory with:
yes @{upstream} | head -1000 | git rev-list --stdin
We can fix this by skipping setup when branch->merge is
already non-NULL.
In addition to those two fixes, this patch pushes the "do we
need to setup merge?" logic down into set_merge, where it is
a bit easier to follow.

remote.c: untangle error logic in branch_get_upstream
The error-diagnosis logic in branch_get_upstream was copied
straight from sha1_name.c in the previous commit. However,
because we check all error cases and upfront and then later
diagnose them, the logic is a bit tangled. In particular:
- if branch->merge[0] is NULL, we may end up dereferencing
it for an error message (in practice, it should never be
NULL, so this is probably not a triggerable bug).
- We may enter the code path because branch->merge[0]->dst
is NULL, but we then start our error diagnosis by
checking whether our local branch exists. But that is
only relevant to diagnosing missing merge config, not a
missing tracking ref; our diagnosis may hide the real
problem.
Instead, let's just use a sequence of "if" blocks to check
for each error type, diagnose it, and return NULL.

fetch: ignore wildcarded refspecs that update local symbolic refs
In a repository cloned from somewhere else, you typically have a
symbolic ref refs/remotes/origin/HEAD pointing at the 'master'
remote-tracking ref that is next to it. When fetching into such a
repository with "git fetch --mirror" from another repository that
was similarly cloned, the implied wildcard refspec refs/*:refs/*
will end up asking to update refs/remotes/origin/HEAD with the
object at refs/remotes/origin/HEAD at the remote side, while asking
to update refs/remotes/origin/master the same way. Depending on the
order the two updates happen, the latter one would find that the
value of the ref before it is updated has changed from what the code
expects.
When the user asks to update the underlying ref via the symbolic ref
explicitly without using a wildcard refspec, e.g. "git fetch $there
refs/heads/master:refs/remotes/origin/HEAD", we should still let him
do so, but when expanding wildcard refs, it will result in a more
intuitive outcome if we simply ignore local symbolic refs.
As the purpose of the symbolic ref refs/remotes/origin/HEAD is to
follow the ref it points at (e.g. refs/remotes/origin/master), its
value would change when the underlying ref is updated.
Earlier commit da3efdb (receive-pack: detect aliased updates which
can occur with symrefs, 2010-04-19) fixed a similar issue for "git
push".

fetch: ignore wildcarded refspecs that update local symbolic refs
In a repository cloned from somewhere else, you typically have a
symbolic ref refs/remotes/origin/HEAD pointing at the 'master'
remote-tracking ref that is next to it. When fetching into such a
repository with "git fetch --mirror" from another repository that
was similarly cloned, the implied wildcard refspec refs/*:refs/*
will end up asking to update refs/remotes/origin/HEAD with the
object at refs/remotes/origin/HEAD at the remote side, while asking
to update refs/remotes/origin/master the same way. Depending on the
order the two updates happen, the latter one would find that the
value of the ref before it is updated has changed from what the code
expects.
When the user asks to update the underlying ref via the symbolic ref
explicitly without using a wildcard refspec, e.g. "git fetch $there
refs/heads/master:refs/remotes/origin/HEAD", we should still let him
do so, but when expanding wildcard refs, it will result in a more
intuitive outcome if we simply ignore local symbolic refs.
As the purpose of the symbolic ref refs/remotes/origin/HEAD is to
follow the ref it points at (e.g. refs/remotes/origin/master), its
value would change when the underlying ref is updated.
Earlier commit da3efdb (receive-pack: detect aliased updates which
can occur with symrefs, 2010-04-19) fixed a similar issue for "git
push".

push: introduce REJECT_FETCH_FIRST and REJECT_NEEDS_FORCE
When we push to update an existing ref, if:
* the object at the tip of the remote is not a commit; or
* the object we are pushing is not a commit,
it won't be correct to suggest to fetch, integrate and push again,
as the old and new objects will not "merge". We should explain that
the push must be forced when there is a non-committish object is
involved in such a case.
If we do not have the current object at the tip of the remote, we do
not even know that object, when fetched, is something that can be
merged. In such a case, suggesting to pull first just like
non-fast-forward case may not be technically correct, but in
practice, most such failures are seen when you try to push your work
to a branch without knowing that somebody else already pushed to
update the same branch since you forked, so "pull first" would work
as a suggestion most of the time. And if the object at the tip is
not a commit, "pull first" will fail, without making any permanent
damage. As a side effect, it also makes the error message the user
will get during the next "push" attempt easier to understand, now
the user is aware that a non-commit object is involved.
In these cases, the current code already rejects such a push on the
client end, but we used the same error and advice messages as the
ones used when rejecting a non-fast-forward push, i.e. pull from
there and integrate before pushing again.
Introduce new rejection reasons and reword the messages
appropriately.

branch: report invalid tracking branch as gone
Command "git branch -vv" will report tracking branches, but invalid
tracking branches are also reported. This is because the function
stat_tracking_info() can not distinguish invalid tracking branch
from other cases which it would not like to report, such as
there is no upstream settings at all, or nothing is changed between
one branch and its upstream.
Junio suggested missing upstream should be reported [1] like:
$ git branch -v -v
master e67ac84 initial
* topic 3fc0f2a [topicbase: gone] topic
$ git status
# On branch topic
# Your branch is based on 'topicbase', but the upstream is gone.
# (use "git branch --unset-upstream" to fixup)
...
$ git status -b -s
## topic...topicbase [gone]
...
In order to do like that, we need to distinguish these three cases
(i.e. no tracking, with configured but no longer valid tracking, and
with tracking) in function stat_tracking_info(). So the refactored
function stat_tracking_info() has three return values: -1 (with "gone"
base), 0 (no base), and 1 (with base).
If the caller does not like to report tracking info when nothing
changed between the branch and its upstream, simply checks if
num_theirs and num_ours are both 0.

branch: report invalid tracking branch as gone
Command "git branch -vv" will report tracking branches, but invalid
tracking branches are also reported. This is because the function
stat_tracking_info() can not distinguish invalid tracking branch
from other cases which it would not like to report, such as
there is no upstream settings at all, or nothing is changed between
one branch and its upstream.
Junio suggested missing upstream should be reported [1] like:
$ git branch -v -v
master e67ac84 initial
* topic 3fc0f2a [topicbase: gone] topic
$ git status
# On branch topic
# Your branch is based on 'topicbase', but the upstream is gone.
# (use "git branch --unset-upstream" to fixup)
...
$ git status -b -s
## topic...topicbase [gone]
...
In order to do like that, we need to distinguish these three cases
(i.e. no tracking, with configured but no longer valid tracking, and
with tracking) in function stat_tracking_info(). So the refactored
function stat_tracking_info() has three return values: -1 (with "gone"
base), 0 (no base), and 1 (with base).

Convert lookup_commit* to struct object_id
Convert lookup_commit, lookup_commit_or_die,
lookup_commit_reference, and lookup_commit_reference_gently to take
struct object_id arguments.
Introduce a temporary in parse_object buffer in order to convert this
function. This is required since in order to convert parse_object and
parse_object_buffer, lookup_commit_reference_gently and
lookup_commit_or_die would need to be converted. Not introducing a
temporary would therefore require that lookup_commit_or_die take a
struct object_id *, but lookup_commit would take unsigned char *,
leaving a confusing and hard-to-use interface.
parse_object_buffer will lose this temporary in a later patch.

branch: report invalid tracking branch as gone
Command "git branch -vv" will report tracking branches, but invalid
tracking branches are also reported. This is because the function
stat_tracking_info() can not distinguish invalid tracking branch
from other cases which it would not like to report, such as
there is no upstream settings at all, or nothing is changed between
one branch and its upstream.
Junio suggested missing upstream should be reported [1] like:
$ git branch -v -v
master e67ac84 initial
* topic 3fc0f2a [topicbase: gone] topic
$ git status
# On branch topic
# Your branch is based on 'topicbase', but the upstream is gone.
# (use "git branch --unset-upstream" to fixup)
...
$ git status -b -s
## topic...topicbase [gone]
...
In order to do like that, we need to distinguish these three cases
(i.e. no tracking, with configured but no longer valid tracking, and

remote.c: add command line option parser for "--force-with-lease"
Update "git push" and "git send-pack" to parse this commnd line
option.
The intended sematics is:
* "--force-with-lease" alone, without specifying the details, will
protect _all_ remote refs that are going to be updated by
requiring their current value to be the same as some reasonable
default, unless otherwise specified;
* "--force-with-lease=refname", without specifying the expected
value, will protect that refname, if it is going to be updated,
by requiring its current value to be the same as some reasonable
default.
* "--force-with-lease=refname:value" will protect that refname, if
it is going to be updated, by requiring its current value to be
the same as the specified value; and
* "--no-force-with-lease" will cancel all the previous --force-with-lease on the
command line.
For now, "some reasonable default" is tentatively defined as "the
value of the remote-tracking branch we have for the ref of the
remote being updated", and it is an error if we do not have such a
remote-tracking branch. But this is known to be fragile, its use is
not yet recommended, and hopefully we will find more reasonable
default as we gain experience with this feature. The manual marks
the feature as experimental unless the expected value is specified
explicitly for this reason.
Because the command line options are parsed _before_ we know which
remote we are pushing to, there needs further processing to the
parsed data after we instantiate the transport object to:
* expand "refname" given by the user to a full refname to be
matched with the list of "struct ref" used in match_push_refs()
and set_ref_status_for_push(); and
* learning the actual local ref that is the remote-tracking branch
for the specified remote ref.
Further, some processing need to be deferred until we find the set
of remote refs and match_push_refs() returns in order to find the
ones that need to be checked after explicit ones have been processed
for "--force-with-lease" (no specific details).
These post-processing will be the topic of the next patch.
This option was originally called "cas" (for "compare and swap"),
the name which nobody liked because it was too technical. The
second attempt called it "lockref" (because it is conceptually like
pushing after taking a lock) but the word "lock" was hated because
it implied that it may reject push by others, which is not the way
this option works. This round calls it "force-with-lease". You
assume you took the lease on the ref when you fetched to decide what
the rebased history should be, and you can push back only if the
lease has not been broken.
