Brad Fitzpatrick	41fd4eab5c	envknob: add new package for all the strconv.ParseBool(os.Getenv(..)) A new package can also later record/report which knobs are checked and set. It also makes the code cleaner & easier to grep for env knobs. Change-Id: Id8a123ab7539f1fadbd27e0cbeac79c2e4f09751 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	51976ab3a2	tsweb: add vars for unix process start time and version To be scraped in the Go expvar JSON format, as a string is involved. For a future tool to record when processes restarted exactly, and at what version. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	3700cf9ea4	tsweb: also support LabelMaps from expvar.Map, without metrics We want to use tsweb to format Prometheus-style metrics from our temporary golang.org/x/net/http2 fork, but we don't want http2 to depend on the tailscale.com module to use the concrete type tailscale.com/metrics.LabelMap. Instead, let a expvar.Map be used instead of it's annotated sufficiently in its name. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

julianknodt	3377089583	tsweb: add float64 to logged metrics A previously added metric which was float64 was being ignored in tsweb, because it previously only accepted int64 and ints. It can be handled in the same way as ints. Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago

chungdaniel	e7ac9a4b90	tsweb: refactor JSONHandler to take status code from error if it is present (#905 ) This change is to make JSONHandler error handling intuitive, as before there would be two sources of HTTP status code when HTTPErrors were generated: one as the first return value of the handler function, and one nested inside the HTTPError. Previously, it took the first return value as the status code, and ignored the code inside the HTTPError. Now, it should expect the first return value to be 0 if there is an error, and it takes the status code of the HTTPError to set as the response code.

Josh Bleecher Snyder	3b46655dbb	tsweb: add StatusCodeCounters to HandlerOptions This lets servers using tsweb register expvars that will track the number of requests ending in 200s/300s/400s/500s. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	e98f2c57d6	tsweb: add StdHandlerOpts that accepts an options struct I'm about to add yet another StdHandler option. Time to refactor. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
David Crawshaw	815bf017fc	tsweb: when unwrapping HTTPError, record the user-facing message also in the log There's often some useful piece of information in there not already repeated in the internal error. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	4 years ago
David Crawshaw	dea3ef0597	tsweb: make JSONHandlerFunc implement ReturnHandler, not http.Handler This way something is capable of logging errors on the server. Fixes #766 Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	4 years ago

Brad Fitzpatrick	64334143a1	tsweb: rename Handler to ReturnHandler The name's been bugging me for a long time. I liked neither the overlap between tsweb.Handler and http.Handler, nor the name "ServeHTTPErr" which sounds like it's an error being returned, like it's an error handler and not sometimes a happy path.

David Anderson	2c2dff9559	tsweb: don't panic if we get a tsweb.Error with no embedded error. It's technically weird to return a tsweb.Error with no child err, but it's a sensible thing to want to do, and we shouldn't panic if it happens. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
