Hexadecimal escape in host #2316
Description
hi all
while I used syncthing 12 beta1 I noticed this error logs :
"Failed to parse connection url: tcp://fe80::ccb4::10d2%{04F829EA-**************_-9A6B8511AB9D}:22000 parse tcp://fe80::ccb4:_:10d2%{04F829EA-**************-9A6B8511AB9D}:22000: hexadecimal escape in host"
with the occasional disconnection of the device.
is this a problem of my configuration?
thanks for your time.

I think it's an error caused by Windows device naming conventions (guid) in combination with Go's address parsing... I wonder what's correct here, will look into it.

I think we're missing []s somewhere too.

how can i help you?

Enable STTRACE=log env var, and provide a proper log log with timestamps and lines around it when it happens again.
xMase commented on Sep 26, 2015
i set STTRACE with "set STTRACE=all" and after i restarted syncthing but nothing change is the log file. I use SyncTrayzor.
AudriusButkevicius commented on Sep 26, 2015
You have to launch synctrayzor from the same shell you set the env var, as set is local to the shell.

So I cannot reproduce the same issue.
I seem to get a different error: percent-encoded characters in host, but that's golang/go#7991
Can you replace a few characters in the address with some other characters, rather than blanking them out with stars?

Pretty sure that^ is the problem. We get a local announcement over ipv6, just jam the port on after it with sprintf, and produce something nonsesical. Using net.JoinHostPort which is made to handle this correctly should solve it.

This issue still affects me:

Indeed! We must escape the percent sign before the scope identifier, as per RFC 6874. Or rather, use url.URL to construct the URL string in the first place.
