The value of "uname -s" is by default sent over the wire as a part
of the "version" capability.
* ua/os-version-capability:
agent: advertise OS name via agent capability
t5701: add setup test to remove side-effect dependency
version: extend get_uname_info() to hide system details
version: refactor get_uname_info()
version: refactor redact_non_printables()
version: replace manual ASCII checks with isprint() for clarity
When a server S knows that some objects from a repository are available
from a promisor remote X, S might want to suggest to a client C cloning
or fetching the repo from S that C may use X directly instead of S for
these objects.
Note that this could happen both in the case S itself doesn't have the
objects and borrows them from X, and in the case S has the objects but
knows that X is better connected to the world (e.g., it is in a
$LARGEINTERNETCOMPANY datacenter with petabit/s backbone connections)
than S. Implementation of the latter case, which would require S to
omit in its response the objects available on X, is left for future
improvement though.
Then C might or might not, want to get the objects from X. If S and C
can agree on C using X directly, S can then omit objects that can be
obtained from X when answering C's request.
To allow S and C to agree and let each other know about C using X or
not, let's introduce a new "promisor-remote" capability in the
protocol v2, as well as a few new configuration variables:
- "promisor.advertise" on the server side, and:
- "promisor.acceptFromServer" on the client side.
By default, or if "promisor.advertise" is set to 'false', a server S will
not advertise the "promisor-remote" capability.
If S doesn't advertise the "promisor-remote" capability, then a client C
replying to S shouldn't advertise the "promisor-remote" capability
either.
If "promisor.advertise" is set to 'true', S will advertise its promisor
remotes with a string like:
promisor-remote=<pr-info>[;<pr-info>]...
where each <pr-info> element contains information about a single
promisor remote in the form:
name=<pr-name>[,url=<pr-url>]
where <pr-name> is the urlencoded name of a promisor remote and
<pr-url> is the urlencoded URL of the promisor remote named <pr-name>.
For now, the URL is passed in addition to the name. In the future, it
might be possible to pass other information like a filter-spec that the
client may use when cloning from S, or a token that the client may use
when retrieving objects from X.
It is C's responsibility to arrange how it can reach X though, so pieces
of information that are usually outside Git's concern, like proxy
configuration, must not be distributed over this protocol.
It might also be possible in the future for "promisor.advertise" to have
other values. For example a value like "onlyName" could prevent S from
advertising URLs, which could help in case C should use a different URL
for X than the URL S is using. (The URL S is using might be an internal
one on the server side for example.)
By default or if "promisor.acceptFromServer" is set to "None", C will
not accept to use the promisor remotes that might have been advertised
by S. In this case, C will not advertise any "promisor-remote"
capability in its reply to S.
If "promisor.acceptFromServer" is set to "All" and S advertised some
promisor remotes, then on the contrary, C will accept to use all the
promisor remotes that S advertised and C will reply with a string like:
promisor-remote=<pr-name>[;<pr-name>]...
where the <pr-name> elements are the urlencoded names of all the
promisor remotes S advertised.
In a following commit, other values for "promisor.acceptFromServer" will
be implemented, so that C will be able to decide the promisor remotes it
accepts depending on the name and URL it received from S. So even if
that name and URL information is not used much right now, it will be
needed soon.

We presently use the ".txt" extension for our AsciiDoc files. While not
wrong, most editors do not associate this extension with AsciiDoc,
meaning that contributors don't get automatic editor functionality that
could be useful, such as syntax highlighting and prose linting.
It is much more common to use the ".adoc" extension for AsciiDoc files,
since this helps editors automatically detect files and also allows
various forges to provide rich (HTML-like) rendering. Let's do that
here, renaming all of the files and updating the includes where
relevant. Adjust the various build scripts and makefiles to use the new
extension as well.
Note that this should not result in any user-visible changes to the
documentation.
