- it is in a function which already printing something or is

When pulling from a remote, the full URL including username
is by default added to the commit message. Since it adds
very little value but could be used by malicious people to
glean valid usernames (with matching hostnames), we're far
better off just stripping the username before storing the
remote URL locally.
Note that this patch has no lasting visible effect when
"git pull" does not create a merge commit. It simply
alters what gets written to .git/FETCH_HEAD, which is used
by "git merge" to automagically create its messages.

Earlier, the rsync tests were disabled by default, as they needed a
running rsyncd daemon. This was only due to the limitation that our
rsync transport only allowed full URLs of the form
rsync://<host>/<path>
Relaxing the URLs to allow
rsync:<path>
permitted the change in the tests to run whenever rsync is available,
without requiring a fully configured and running rsyncd.
While at it, the tests were fixed so that they run in directories with a

"git push" enhancement allows the receiving end to report not only its own
refs but refs in repositories it borrows from via the alternate object
store mechanism. By telling the sender that objects reachable from these
extra refs are already complete in the receiving end, the number of
objects that need to be transfered can be cut down.
These entries are sent over the wire with string ".have", instead of the
actual names of the refs. This string was chosen so that they are ignored
by older programs at the sending end. If we sent some random but valid
looking refnames for these entries, "matching refs" rule (triggered when
running "git push" without explicit refspecs, where the sender learns what
refs the receiver has, and updates only the ones with the names of the
refs the sender also has) and "delete missing" rule (triggered when "git
push --mirror" is used, where the sender tells the receiver to delete the
refs it itself does not have) would try to update/delete them, which is
not what we want.
This prepares the send-pack (and "push" that runs native protocol) to
accept extended existing ref information and make use of it. The ".have"
entries are excluded from ref matching rules, and are exempt from deletion
rule while pushing with --mirror option, but are still used for pack
generation purposes by providing more "bottom" range commits.

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.

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().

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

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.

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.
