404 on makeRequest sometimes

[Fayland Lam <fa...@gmail.com>]

does anyone have any clue on 404 return in makeRequest?

the background is:
1, *sometimes*, in most of the time, it works great. but sometimes it 
return 404  on /gadgets/makeRequest
with debug, it returns on ProxyHandler.php function fetchJson. this 
line: $result = $this->fetchContentDivert($url, $method, $signer);
the POST data (part of) is
authz    signed
bypassSpecCache    0
contentType    JSON
getSummaries    false
headers   
httpMethod    GET
signOwner    true
signViewer    true

it's RSA makeRequest as described here 
http://wiki.opensocial.org/index.php?title=Validating_Signed_Requests

2, we tried to wget the url by a Perl script with wget shell and all of 
them are turn 200 HTTP status, many times. so that's not the problem of 
the network.

3, the 404 number reduced a lot after I set memcached in container.php
'data_cache' => 'CacheMemcache',

4, there is 7 makeRequest on one application. and usually 0 failure. but 
sometimes, 1 failure or 2 failures. and not the same url every time.

I tried to read the code, but lost at RemoteContentRequest.php 
SigningFetcher.php, can someone do me a favor to tell me which file, 
which line do the request to the remote url?

Thanks.

Hey Fayland,

Fixing this might be as simple as increasing the fetch timeout
(curl_connection_timeout in config/container.php), random timeouts sounds
exactly like the behaviour you're seeing.

The actual default fetching code is located in
shindig/php/src/common/sample/BasicRemoteContentFetcher.php
