In some "simple" centralized workflows, users expect remote tracking
branch names to match local branch names. "git push" pushes to the
remote version/instance of the branch, and "git pull" pulls any changes
to the remote branch (changes made by the same user in another place, or
by other users).
This expectation is supported by the push.default default option "simple"
which refuses a default push for a mismatching tracking branch name, and
by the new branch.autosetupmerge option, "simple", which only sets up
remote tracking for same-name remote branches.
When a new branch has been created by the user and has not yet been
pushed (and push.default is not set to "current"), the user is prompted
with a "The current branch %s has no upstream branch" error, and
instructions on how to push and add tracking.
This error is helpful in that following the advice once per branch
"resolves" the issue for that branch forever, but inconvenient in that
for the "simple" centralized workflow, this is always the right thing to
do, so it would be better to just do it.
Support this workflow with a new config setting, push.autoSetupRemote,
which will cause a default push, when there is no remote tracking branch
configured, to push to the same-name on the remote and --set-upstream.
Also add a hint offering this new option when the "The current branch %s
has no upstream branch" error is encountered, and add corresponding tests.

With the default push.default option, "simple", beginners are
protected from accidentally pushing to the "wrong" branch in
centralized workflows: if the remote tracking branch they would push
to does not have the same name as the local branch, and they try to do
a "default push", they get an error and explanation with options.
There is a particular centralized workflow where this often happens:
a user branches to a new local topic branch from an existing
remote branch, eg with "checkout -b feature1 origin/master". With
the default branch.autosetupmerge configuration (value "true"), git
will automatically add origin/master as the upstream tracking branch.
When the user pushes with a default "git push", with the intention of
pushing their (new) topic branch to the remote, they get an error, and
(amongst other things) a suggestion to run "git push origin HEAD".
If they follow this suggestion the push succeeds, but on subsequent
default pushes they continue to get an error - so eventually they
figure out to add "-u" to change the tracking branch, or they spelunk
the push.default config doc as proposed and set it to "current", or
some GUI tooling does one or the other of these things for them.
When one of their coworkers later works on the same topic branch,
they don't get any of that "weirdness". They just "git checkout
feature1" and everything works exactly as they expect, with the shared
remote branch set up as remote tracking branch, and push and pull
working out of the box.
The "stable state" for this way of working is that local branches have
the same-name remote tracking branch (origin/feature1 in this
example), and multiple people can work on that remote feature branch
at the same time, trusting "git pull" to merge or rebase as required
for them to be able to push their interim changes to that same feature
branch on that same remote.
(merging from the upstream "master" branch, and merging back to it,
are separate more involved processes in this flow).
There is a problem in this flow/way of working, however, which is that
the first user, when they first branched from origin/master, ended up
with the "wrong" remote tracking branch (different from the stable
state). For a while, before they pushed (and maybe longer, if they
don't use -u/--set-upstream), their "git pull" wasn't getting other
users' changes to the feature branch - it was getting any changes from
the remote "master" branch instead (a completely different class of
changes!)
An experienced git user might say "well yeah, that's what it means to
have the remote tracking branch set to origin/master!" - but the
original user above didn't *ask* to have the remote master branch
added as remote tracking branch - that just happened automatically
when they branched their feature branch. They didn't necessarily even
notice or understand the meaning of the "set up to track 'origin/master'"
message when they created the branch - especially if they are using a
GUI.
Looking at how to fix this, you might think "OK, so disable auto setup
of remote tracking - set branch.autosetupmerge to false" - but that
will inconvenience the *second* user in this story - the one who just
wanted to start working on the topic branch. The first and second
users swap roles at different points in time of course - they should
both have a sane configuration that does the right thing in both
situations.
Make this "branches have the same name locally as on the remote"
workflow less painful / more obvious by introducing a new
branch.autosetupmerge option called "simple", to match the same-name
"push.default" option that makes similar assumptions.
This new option automatically sets up tracking in a *subset* of the
current default situations: when the original ref is a remote tracking
branch *and* has the same branch name on the remote (as the new local
branch name).
Update the error displayed when the 'push.default=simple' configuration
rejects a mismatching-upstream-name default push, to offer this new
branch.autosetupmerge option that will prevent this class of error.
With this new configuration, in the example situation above, the first
user does *not* get origin/master set up as the tracking branch for
the new local branch. If they "git pull" in their new local-only
branch, they get an error explaining there is no upstream branch -
which makes sense and is helpful. If they "git push", they get an
error explaining how to push *and* suggesting they specify
--set-upstream - which is exactly the right thing to do for them.
This new option is likely not appropriate for users intentionally
implementing a "triangular workflow" with a shared upstream tracking
branch, that they "git pull" in and a "private" feature branch that
they push/force-push to just for remote safe-keeping until they are
ready to push up to the shared branch explicitly/separately. Such
users are likely to prefer keeping the current default
merge.autosetupmerge=true behavior, and change their push.default to
"current".
Also extend the existing branch tests with three new cases testing
this option - the obvious matching-name and non-matching-name cases,
and also a non-matching-ref-type case. The matching-name case needs to
temporarily create an independent repo to fetch from, as the general
strategy of using the local repo as the remote in these tests
precludes locally branching with the same name as in the "remote".

"git push $there --delete ''" should have been diagnosed as an
error, but instead turned into a matching push, which has been
corrected.
* jc/push-delete-nothing:
push: do not turn --delete '' into a matching push
When we added a syntax sugar "git push remote --delete <ref>" to
"git push" as a synonym to the canonical "git push remote :<ref>"
syntax at f517f1f2 (builtin-push: add --delete as syntactic sugar
for :foo, 2009-12-30), we weren't careful enough to make sure that
<ref> is not empty.
Blindly rewriting "--delete <ref>" to ":<ref>" means that an empty
string <ref> results in refspec ":", which is the syntax to ask for
"matching" push that does not delete anything.
Worse yet, if there were matching refs that can be fast-forwarded,
they would have been published prematurely, even if the user feels
that they are not ready yet to be pushed out, which would be a real
disaster.

"git push --force-with-lease[=<ref>]" can easily be misused to lose
commits unless the user takes good care of their own "git fetch".
A new option "--force-if-includes" attempts to ensure that what is
being force-pushed was created after examining the commit at the
tip of the remote ref that is about to be force-replaced.
* sk/force-if-includes:
t, doc: update tests, reference for "--force-if-includes"
push: parse and set flag for "--force-if-includes"
push: add reflog check for "--force-if-includes"
The previous commit added the necessary machinery to implement the
"--force-if-includes" protection, when "--force-with-lease" is used
without giving exact object the remote still ought to have. Surface
the feature by adding a command line option and a configuration
variable to enable it.
- Add a flag: "TRANSPORT_PUSH_FORCE_IF_INCLUDES" to indicate that the
new option was passed from the command line of via configuration
settings; update command line and configuration parsers to set the
new flag accordingly.
- Introduce a new configuration option "push.useForceIfIncludes", which
is equivalent to setting "--force-if-includes" in the command line.
- Update "remote-curl" to recognize and pass this option to "send-pack"
when enabled.
- Update "advise" to catch the reject reason "REJECT_REF_NEEDS_UPDATE",
set when the ref status is "REF_STATUS_REJECT_REMOTE_UPDATED" and
(optionally) print a help message when the push fails.
- The new option is a "no-op" in the following scenarios:
* When used without "--force-with-lease".
* When used with "--force-with-lease", and if the expected commit
on the remote side is specified as an argument.

map_refspec() either returns the passed in ref string or a detached
strbuf. This makes it hard for callers to release the possibly
allocated memory, and set_refspecs() consequently leaks it.
Let map_refspec() append any refspecs directly and release its own
strbufs after use. Rename it to refspec_append_mapped() and don't
return anything to reflect its increased responsibility.
set_refspecs() also leaks its strbufs. Do the same here and directly
call refspec_append() in each if branch instead of holding onto a
detached strbuf, then dispose of the allocated memory after use. We
need to add an else branch for the final call because all the other
conditional branches already add their formatted refspec now.
setup_push_upstream() and setup_push_current() forgot to release their
strbufs as well; plug these leaks, too, while at it.
None of these leaks were likely to impact users, because the number
and sizes of refspecs are usually small and the allocations are only
done once per program run. Clean them up nevertheless, as another
step on the long road towards zero memory leaks.

In the codebase, there are many options which use OPTION_CALLBACK in a
plain ol' struct definition. However, we have the OPT_CALLBACK and
OPT_CALLBACK_F macros which are meant to abstract these plain struct
definitions away. These macros are useful as they semantically signal to
developers that these are just normal callback option with nothing fancy
happening.
Replace plain struct definitions of OPTION_CALLBACK with OPT_CALLBACK or
OPT_CALLBACK_F where applicable. The heavy lifting was done using the
following (disgusting) shell script:
#!/bin/sh
do_replacement () {
tr '\n' '\r' |
sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\s*0,\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK(\1,\2,\3,\4,\5,\6)/g' |
sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK_F(\1,\2,\3,\4,\5,\6,\7)/g' |
tr '\r' '\n'
}
for f in $(git ls-files \*.c)
do
do_replacement <"$f" >"$f.tmp"
mv "$f.tmp" "$f"
done
The result was manually inspected and then reformatted to match the
style of the surrounding code. Finally, using
`git grep OPTION_CALLBACK \*.c`, leftover results which were not handled
by the script were manually transformed.

Pushes with --all, or refspecs are disallowed when --mirror is given

'do_push()', so the checks would miss it entirely.
This leads to surprises for users [*1*].
