Paul Hammant updated SVN-4738:
------------------------------
Description:
It would be cool if svn.exe (the client) could follow HTTP return code '302'
during svn-co and svn-up operations. Possibly also, language bindings and a
spec update in documentation.
I'm thinking that this is just for GET* of resources, and that someone who's
managed to +front+ their Mod_Dav_Svn with something that can do redirects for
selected resources. Say to resources in S3.
(request)
GET /repos/asf/!svn/rvr/1234/path/to/movie.mp4 HTTP/1.1
Host: [svn.example.com|http://svn.example.com/]
User-Agent: SVN/1.9.7 (x86_64-apple-darwin17.3.0) serf/1.3.9
Accept-Encoding: gzip
(response)
302 Found
Location [https://foobar.s3.amazonaws.com/1234]/path/to/movie.mp4
(subsequent request)
GET 1234/path/to/movie.mp4 HTTP/1.1
Host: [foobar.s3.amazonaws.com|http://foobar.s3.amazonaws.com/]
User-Agent: SVN/1.9.7 (x86_64-apple-darwin17.3.0) serf/1.3.9
Accept-Encoding: gzip
(Amazon itself does more 302's here, probably)
You could make a general case that any (or more than just GET) of the HTTP
methods could be redirectable but discussing GET is a narrow case for the sake
of a debate.
Also, you could make a case for 307 responses too -
[https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/307]
Rationale: Overall system throughput is what I'm aiming at - large payloads
for thousands of users concurrently (and spread worldwide) are a focus area for
me. Latency increasing (for each redirected GET start to stream) isn't a worry
for me.
Note: The Subversion client already handles redirects when initiating HTTP(S),
but this is for following GET operations after the initial connect.
Note2: Redirects to other sub-domains *would* assume that the same Basic Auth
(if supplied via --username and --password), whereas redirects to other domains
*would not* use the same Basic Auth (if supplied via --username and --password)
and prompt again or pull from those available in ~/.subversion/
> Subversion clients following HTTP 302 response codes.
