information fed from the remote end.</p></div>
|
|
<div class="paragraph"><p>This command is usually not invoked directly by the end user.
|
|
The UI for the protocol is on the <em>git send-pack</em> side, and the
|
|
program pair is meant to be used to push updates to a remote
|
|
repository. For pull operations, see <a href="git-fetch-pack.html">git-fetch-pack(1)</a>.</p></div>
|
|
<div class="paragraph"><p>The command allows for the creation and fast-forwarding of sha1 refs
|
|
(heads/tags) on the remote end (strictly speaking, it is the
|
|
local end <em>git-receive-pack</em> runs, but to the user who is sitting at
|
|
the send-pack end, it is updating the remote. Confused?)</p></div>
|
|
<div class="paragraph"><p>There are other real-world examples of using update and
|
|
post-update hooks found in the Documentation/howto directory.</p></div>
|
|
<div class="paragraph"><p><em>git-receive-pack</em> honours the receive.denyNonFastForwards config
|
|
option, which tells it if updates to a ref should be denied if they
|
|
are not fast-forwards.</p></div>
|
|
<div class="paragraph"><p>A number of other receive.* config options are available to tweak
|
|
its behavior, see <a href="git-config.html">git-config(1)</a>.</p></div>

Bypasses the connectivity checks that validate the existence of all

objects in the transitive closure of reachable objects. This option is
|
|
intended for server operators that want to implement their own object
|
|
connectivity validation outside of Git. This is useful in such cases
|
|
where the server-side knows additional information about how Git is
|
|
being used and thus can rely on certain guarantees to more efficiently
|
|
compute object connectivity that Git itself cannot make. Usage of this
|
|
option without a reliable external mechanism to ensure full reachable
|
|
object connectivity risks corrupting the repository and should not be
|
|
used in the general case.

Pushes which fail due to problems with the incoming pack, missing

The <code>pre-receive</code> hook MUST NOT update any refs to point to

quarantined objects. Other programs accessing the repository will

not be able to see the objects (and if the pre-receive hook fails,

those refs would become corrupted). For safety, any ref updates

from within <code>pre-receive</code> are automatically rejected.
