Upload to GCMMap only in https now #2

Open snarkbe opened 5 years ago

snarkbe commented 5 years ago

The upload to gmcmap.com does not work anymore. journalctl shows

Apr 21 09:34:35 pihole gclog[30652]: CPM: 28 (= 1662/60), Timestamp: Sun Apr 21 07:33:35 2019
Apr 21 09:34:36 pihole gclog[30652]: [WARNING] Upload to gmcmap.com failed.

When I try to simulate an upload from command-line, I get:

So it looks like they're now redirecting all requests to https, which is not supported by the code in gclog.c .

Other people are discussing vaguely similar issues at the GQ forum

Either the forced upgrade to https was not planned, or they have not measured the consequences.

stelas commented 5 years ago

HTTPS support has been on the todo list for a year now. :(

The easiest way would be to use libcurl instead of the simple TCP client tcpcli.h. But that would break the compatibility with 4MB flash OpenWrt routers.

snarkbe commented 5 years ago

I understand. But if they keep the redirect to https, it won't work anymore for all supported plaftorms, not only for OpenWrt.

stelas commented 5 years ago

I'll see how complex it is to write a wrapper for mbed TLS and integrate it. But that will take a while...

snarkbe commented 5 years ago

While it'll be nice to have https included later, it's not urgent. GQ has reckoned there was an issue at their side:

Sorry guys we are trying to fix the issues. Looks like https problem.
