send-pack: fix parsing of --force-with-lease option
The last argument for parse_push_cas_option() is if it is "unset"
(i.e. --no-force-with-lease), and we are parsing the option with an
explicit value here, so it has to be 0.
t5540/5541: smart-http does not support "--force-with-lease"
The push() method in remote-curl.c is not told and does not pass the
necessary information to underlying send-pack, so this extension
does not yet work. Leave a note in the test suite.
Prepare two repositories, src and dst, the latter of which is a
clone of the former (with tracking branches), and push from the
latter into the former, with various --force-with-lease options.
This teaches the deepest part of the callchain for "git push" (and
"git send-pack") to enforce "the old value of the ref must be this,
otherwise fail this push" (aka "compare-and-swap" / "--lockref").
push --force-with-lease: implement logic to populate old_sha1_expect[]
This plugs the push_cas_option data collected by the command line
option parser to the transport system with a new function
apply_push_cas(), which is called after match_push_refs() has
already been called.
At this point, we know which remote we are talking to, and what
remote refs we are going to update, so we can fill in the details
that may have been missing from the command line, such as
(1) what abbreviated refname the user gave us matches the actual
refname at the remote; and
(2) which remote-tracking branch in our local repository to read
the value of the object to expect at the remote.
to populate the old_sha1_expect[] field of each of the remote ref.
As stated in the documentation, the use of remote-tracking branch
as the default is a tentative one, and we may come up with a better
logic as we gain experience.
Still nobody uses this information, which is the topic of the next
patch.
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.
The command line parser of "git push" for "--tags", "--delete", and
"--thin" options still used outdated OPT_BOOLEAN. Because these
options do not give escalating levels when given multiple times,
they should use OPT_BOOL.
The definition of "struct ref" in "cache.h", a header file so
central to the system, always confused me. This structure is not
about the local ref used by sha1-name API to name local objects.
It is what refspecs are expanded into, after finding out what refs
the other side has, to define what refs are updated after object
transfer succeeds to what values. It belongs to "remote.h" together
with "struct refspec".
While we are at it, also move the types and functions related to the
Git transport connection to a new header file connect.h

fixup-builtins: retire an old transition helper script
This script was added in 36e5e70 (Start deprecating "git-command" in

transition away from dashed forms.
It has already been used to help the transision and served its
purpose, and is no longer very useful for follow-up work, because
the majority of remaining matches it finds are false positives.

intentionally, as when the user expressly meant to note that the commit

the original commit with :/msg; or out of laziness, as when the user could
remember how to refer to the fixup but not the original).
