logging - where does go write panic logs? -

-

i installed golang on redhat server through epel. i'm trying analyze panic logs can't find logs stored. hint ? there no trace in /var/log

      func main() {              http.handlefunc("/", panicrecover(test))             log.fatal(http.listenandserve(":80", nil))         }        func test(){         out, err := exec.command("echo ", "something").output()             if err != nil {                 log.panic(err)              }     }   func panicrecover(f func(w http.responsewriter, r *http.request)) func(w http.responsewriter, r *http.request) {     return func(w http.responsewriter, r *http.request) {         defer func() {             if r := recover(); r != nil {                 log.printf("panic recovered:%s\n", r)             }         }()         f(w, r)     }

to stderr.

for example,

package main  import "log"  func main() {     log.panic("log.panic stderr") }   $ go run panic.go 2>stderr.txt

stderr.txt file:

2014/06/09 00:30:54 log.panic stderr panic: log.panic stderr  goroutine 16 [running]: runtime.panic(0x497180, 0xc2080001a0)     /home/peter/go/src/pkg/runtime/panic.c:279 +0xf5 log.panic(0x7f88770fff20, 0x1, 0x1)     /home/peter/go/src/pkg/log/log.go:307 +0xb6 main.main()     /home/peter/gopath/src/so/panic.go:6 +0xa7  goroutine 17 [runnable]: runtime.mheap_scavenger()     /home/peter/go/src/pkg/runtime/mheap.c:507 runtime.goexit()     /home/peter/go/src/pkg/runtime/proc.c:1445  goroutine 18 [runnable]: bgsweep()     /home/peter/go/src/pkg/runtime/mgc0.c:1976 runtime.goexit()     /home/peter/go/src/pkg/runtime/proc.c:1445  goroutine 19 [runnable]: runfinq()     /home/peter/go/src/pkg/runtime/mgc0.c:2606 runtime.goexit()     /home/peter/go/src/pkg/runtime/proc.c:1445 exit status 2

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
