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.

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: 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:

(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:

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:

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.

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.

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: 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'.
