AltostratusI found that this upvar statement doesn't work (it crashes later when entering the foreach loop):
upvar 1 $mylog log
From what I understand, you're passing "log" already as a parameter to the hsllog proc and then do a reference from $mylog (which should be a copy of log?) back to yourself? I can't wrap my head around that. Any way I changed the name of the "log" variable inside hsllog proc to "alog", i.e. "upvar 1 $mylog alog" and used alog in the foreach loop instead. That works as expected…
Also you can check http2 version by using this instead:
if {[HTTP2::version] != 0} {
set log(http_version) [HTTP2::version]
} else {
set log(http_version) [HTTP::version]
}
