I'm not sure about this... Since the unit test requires the wocky http proxy, then it probably should instantiate it directly instead of relying on priorities. But I can see that the unit test code specifically has a test that asserts whether the factory instantiated proxy is the wocky one, which may be there for a reason.

Maybe also this code was written in an era where GIO had no default http proxy and now maybe it has, so the wocky one is useless. I wonder if gabble works fine with a proxy without this patch and which proxy class is actually instantiated.

That's a really good point. I'm not even sure how the proxy is supposed to work, making it pretty hard to test to see if its working.

Looks like I was right about that.

The wocky proxy code obviously made its way into glib, so we no longer need it around in wocky.

George Kiagiadakis found that wocky-http-proxy was modified and became part of gio as https://git.gnome.org/browse/glib/plain/gio/ghttpproxy.c

Diffing wocky-http-proxy and ghttpproxy shows a few meaningful differences.

Without the above patch I get errors like this:

ERROR:wocky-http-proxy-test.c:229:server_thread: assertion failed (base64_cred == received_cred): ("QWxhZGRpbjpvcGVuIHNlc2FtZQ==" == "Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==")

wocky-http-proxy.c (-) used a hard coded "Basic", while the ghttpproxy.c (+) includes "Basic " as part of the credential

     }
 
The other solution might be to be drop the wocky-http-proxy, and update the wocky-proxy tests to be compatible with giohttpproxy

[PATCH 1/2] Remove wocky-http-proxy, upstreamed in GIO now

Created attachment 124877 [details] [review]
[PATCH 2/2] Bump required glib version to 2.44, as we now depend on  GIO http proxy

Code looks good to me. I was briefly confused by removing g_type_init until I read the comment that it was deprecated.

Before applying it wocky-http-proxy-test has errors, after applying and compiling wocky-http-proxy-test passes.


Although after fixing these tests I get authentication errors in other tests, but that appears to be something else, so I opened a different bug for it.
