tcp/ip compression

[pivotgrind <pi...@hotmail.com>]

is there any plan to include tcp/ip compression in subversion?  (like in cvs)

looks like a promising project, I am very interested in seeing the security authorization feature.  keep up the good work.

Sorry, that part of the design doc is waaaaay old.  We use apache to
do authentication, but *authorization* is a different story.

For now, you need to use apache's <Location> directives (in
httpd.conf) to restrict what certain users can and cannot do in the
repository.  You can also use pre-commit hook scripts to do the same,
with much finer granularity.  But this all has to be done in a
home-made way.

Someday after 1.0, we're thinking about putting real ACLs into the
repository filesystem, provided our heads don't explode while thinking
about it.

Probably not in the way described in that doc; we're depending on
Apache for a lot more now.  (Sorry not to provide more details;
they're out there, just don't have time to hunt down the exact notes
and source files right now.)

Yes the docs should be updated :-).  Right we're concentrating on
Alpha code fixes, though.

thanks for the fast reply...  i guess what i meant was tcp/ip compression in
the sense that cvs uses it.  (basically the -z # option).  it sounds like
svn will be just as capable.

another question, are you still planning on implementing the security
features outlined in the design doc?

thanks again.

Authorization
By authorization, we mean answering the question:

  "Is user X allowed to perform action Y on data Z?"

The Subversion filesystem provides a single interface for answering this
question.

CVS does tcp/ip compression?  I know it uses zlib to compress the data
it sends, but that's different from actual tcp/ip level compression,
if I'm not mistaken.

I don't think we have any plans to do this, and am not sure what
advantages it would bring, considering that application-protocol-level
compression will pretty much take care of our compression needs.

Read the Design document... our server is apache.  That means we can
use mod_deflate over the wire (zlib), and can use all the
authentication features that apache already has.
