nginx-tests: proxy_unfinished.t test 'no proxy temp' does not work

[Markus Linnala]

nginx-tests proxy_unfinished.t last test 'no proxy temp' does not work as nginx does not write to proxy_temp.

This is obvious from error_log as there is no mention of error writing to proxy_temp.

I'm using stock nginx 1.5.13 with sub module.

If I modify test (attached), I can get error like

2014/04/14 18:03:37 [crit] 13385#0: *1 open() "/tmp/nginx-test-hZk1LOj63E/proxy_temp/0000000001" failed (13: Permission denied) while reading upstream, client: 127.0.0.1, server: localhost, request: "GET /proxy/big.html HTTP/1.1", upstream: "http://127.0.0.1:8081/proxy/big.html", host: "localhost"

And test also fails to do what is intended as it does not output anything.

The test in question depends on various socket buffer sizes and may not be triggered on your particular system if you are using big socket buffers. It works fine here though:

$ TEST_NGINX_CATLOG=1 prove -v proxy_unfinished.t | grep 'Permission denied'
2014/04/14 19:37:28 [crit] 83606#0: *33 open() "/tmp/nginx-test-9dVMEWSyjb/proxy_temp/0000000007" failed (13: Permission denied) while reading upstream, client: 127.0.0.1, server: localhost, request: "GET /proxy/big.html HTTP/1.1", upstream: "http://127.0.0.1:8080/local/big.html", host: "localhost"
