Daniel Barkalow 2d5c298f91 Mark the list of refs to fetch as const
Fetching the objects doesn't actually modify the list in any of the
code paths, so this will allow code that fetches the entire (const)
list of available refs to just pass the list in directly.

This makes a struct ref able to represent a symref, and makes http.c
able to recognize one, and makes transport.c look for "HEAD" as a ref
in the list, and makes it dereference symrefs for the resulting ref,

Shawn O. Pearce 41fa7d2eae Teach git-fetch to exploit server side automatic tag following
If the remote peer upload-pack process supports the include-tag
protocol extension then we can avoid running a second fetch cycle
on the client side by letting the server send us the annotated tags
along with the objects it is packing for us.  In the following graph
we can now fetch both "tag1" and "tag2" on the same connection that
we fetched "master" from the remote when we only have L available
on the local side:

         T - tag1          S - tag2
        /                 /
   L - o ------ o ------ B
    \                     \
     \                     \
      origin/master         master

The objects for "tag1" are implicitly downloaded without our direct
knowledge.  The existing "quickfetch" optimization within git-fetch
discovers that tag1 is complete after the first connection and does
not open a second connection.

We always report to the user the list of refs we got from the first

Mike Hommey 9fc6440d78 Set proxy override with http_init()
In transport.c, proxy setting (the one from the remote conf) was set through
curl_easy_setopt() call, while http.c already does the same with the
http.proxy setting. We now just use this infrastructure instead, and make
http_init() now take the struct remote as argument so that it can take the
http_proxy setting from there, and any other property that would be added
later.

At the same time, we make get_http_walker() take a struct remote argument
too, and pass it to http_init(), which makes remote defined proxy be used
for more than get_refs_via_curl().

We leave out http-fetch and http-push, which don't use remotes for the
moment, purposefully.

Mike Hommey b26768e256 Work around curl-gnutls not liking to be reinitialized
curl versions 7.16.3 to 7.18.0 included had a regression in which https
requests following curl_global_cleanup/init sequence would fail with ASN1
parser errors with curl-gnutls. Such sequences happen in some cases such
as git fetch.

We work around this by removing the http_init and http_cleanup calls from

Daniel Barkalow ba227857d2 Reduce the number of connects when fetching
This shares the connection between getting the remote ref list and
getting objects in the first batch. (A second connection is still used
to follow tags).

When we do not fetch objects (i.e. either ls-remote disconnects after
getting list of refs, or we decide we are already up-to-date), we
clean up the connection properly; otherwise the connection is left
open in need of cleaning up to avoid getting an error message from
the remote end when ssh is used.

Junio C Hamano c6bc400585 do not discard status in fetch_refs_via_pack()
The code calls fetch_pack() to get the list of refs it fetched, and
discards refs and always returns 0 to signal success.

But builtin-fetch-pack.c::fetch_pack() has error cases.  The function
returns NULL if error is detected (shallow-support side seems to choose
to die but I suspect that is easily fixable to error out as well).

Make fetch_refs_via_pack() propagate that error to the caller.

Junio C Hamano 90446a0009 bundle transport: fix an alloc_ref() call
Currently alloc_ref() expects the length of the refname plus 1
as its parameter, prepares that much space and returns a "ref"
structure for the caller to fill the refname.  One caller in
transport.c::get_refs_from_bundle() however allocated one byte
less.

It may be a good idea to change the calling convention to give
alloc_ref() the length of the refname, but that clean-up can be
done in a separate patch.  This patch only fixes the bug and
makes all callers consistent.

There was also one overallocation in connect.c, which would not
hurt but was wasteful.  This patch fixes it as well.

Shawn O. Pearce 50ab5fd3fc Ensure builtin-fetch honors {fetch,transfer}.unpackLimit
The only way to configure the unpacking limit is currently through
the .git/config (or ~/.gitconfig) mechanism as we have no existing
command line option interface to control this threshold on a per
invocation basis.  This was intentional by design as the storage
policy of the repository should be a repository-wide decision and
should not be subject to variations made on individual command
executions.

Earlier builtin-fetch was bypassing the unpacking limit chosen by
the user through the configuration file as it did not reread the
configuration options through fetch_pack_config if we called the
internal fetch_pack() API directly.  We now ensure we always run the
config file through fetch_pack_config at least once in this process,
thereby setting our unpackLimit properly.

Shawn O. Pearce fa74052922 Always obtain fetch-pack arguments from struct fetch_pack_args
Copying the arguments from a fetch_pack_args into static globals
within the builtin-fetch-pack module is error-prone and may lead
rise to cases where arguments supplied via the struct from the
new fetch_pack() API may not be honored by the implementation.

Here we reorganize all of the static globals into a single static
struct fetch_pack_args instance and use memcpy() to move the data
from the caller supplied structure into the globals before we
execute our pack fetching implementation.  This strategy is more
robust to additions and deletions of properties.

As keep_pack is a single bit we have also introduced lock_pack to
mean not only download and store the packfile via index-pack but
also to lock it against repacking by creating a .keep file when
the packfile itself is stored.  The caller must remove the .keep
file when it is safe to do so.

Shawn O. Pearce 824d5776c3 Refactor struct transport_ops inlined into struct transport
Aside from reducing the code by 20 lines this refactoring removes
a level of indirection when trying to access the operations of a
given transport "instance", making the code clearer and easier to
follow.

It also has the nice effect of giving us the benefits of C99 style
struct initialization (namely ".fetch = X") without requiring that
level of language support from our compiler.  We don't need to worry
about new operation methods being added as they will now be NULL'd
out automatically by the xcalloc() we use to create the new struct
transport we supply to the caller.

This pattern already exists in struct walker, so we already have
a precedent for it in Git.  We also don't really need to worry
about any sort of performance decreases that may occur as a result
of filling out 4-8 op pointers when we make a "struct transport".
The extra few CPU cycles this requires over filling in the "struct
transport_ops" is killed by the time it will take Git to actually
*use* one of those functions, as most transport operations are
going over the wire or will be copying object data locally between
two directories.

Shawn O. Pearce ab865e6eec Avoid printing unnecessary warnings during fetch and push
If a transport doesn't support an option we already are telling
the higher level application (fetch or push) that the option is not
valid by sending back a >0 return value from transport_set_option
so there's not a strong motivation to have the function perform the
output itself.  Instead we should let the higher level application
do the output if it is necessary.  This avoids always telling the
user that depth isn't supported on HTTP urls even when they did
not pass a --depth option to git-fetch.

If the user passes an option and the option value is invalid we now
properly die in git-fetch instead of just spitting out a message
and running anyway.  This mimics prior behavior better where
incorrect/malformed options are not accepted by the process.

Shawn O. Pearce 8eb554ae62 Cleanup duplicate initialization code in transport_get
We always allocate and return a struct transport* right now as every
URL is considered to be a native Git transport if it is not rsync,
http/https/ftp or a bundle.  So we can simplify the initialization
of a new transport object by performing one xcalloc call and filling
in only the attributes required.

Shawn O. Pearce b6abb48a15 Don't bother passing ref log details to walker in builtin-fetch
When using the walker API within builtin-fetch we don't allow
it to update refs locally; instead that action is reserved for
builtin-fetch's own main loop once the objects have actually
been downloaded.

Passing NULL here will bypass the unnecessary malloc/free of a
string buffer within the walker API.  That buffer is never used
because the prior argument (the refs to update) is also NULL.

Shawn O. Pearce e4cd6c7a20 Backup the array passed to fetch_pack so we can free items
fetch_pack() can call remove_duplicates() on its input array and
this will possibly overwrite an earlier entry with a later one if
there are any duplicates in the input array.  In such a case the
caller here might then attempt to free an item multiple times as
it goes through its cleanup.

I also forgot to free the heads array we pass down into fetch_pack()
when I introduced the allocation of it in this function during my
builtin-fetch cleanup series.  Better free it while we are here
working on related memory management fixes.

Shawn O. Pearce 1788c39cd0 Remove pack.keep after ref updates in git-fetch
If we are using a native packfile to perform a git-fetch invocation
and the received packfile contained more than the configured limits
of fetch.unpackLimit/transfer.unpackLimit then index-pack will output
a single line saying "keep\t$sha1\n" to stdout.  This line needs to
be captured and retained so we can delete the corresponding .keep
file ("$GIT_DIR/objects/pack/pack-$sha1.keep") once all refs have
been safely updated.

This trick has long been in use with git-fetch.sh and its lower level
helper git-fetch--tool as a way to allow index-pack to save the new
packfile before the refs have been updated and yet avoid a race with
any concurrently running git-repack process.  It was unfortunately
lost when git-fetch.sh was converted to pure C and fetch--tool was
no longer being invoked.

Shawn O. Pearce 425b139313 Simplify fetch transport API to just one function
Commit walkers need to know the SHA-1 name of any objects they
have been asked to fetch while the native pack transport only
wants to know the names of the remote refs as the remote side
must do the name->SHA-1 translation.

Since we only have three fetch implementations and one of them
(bundle) doesn't even need the name information we can reduce
the code required to perform a fetch by having just one function
and passing of the filtered list of refs to be fetched.  Each
transport can then obtain the information it needs from that ref
array to construct its own internal operation state.

Shawn O. Pearce 7a2bff4593 Replace custom memory growth allocator with ALLOC_GROW
The ALLOC_GROW macro is a shorter way to implement an array that
grows upon demand as additional items are added to it.  We have
mostly standardized upon its use within git and transport.c is
not an exception.
