Maisem Ali	309c0a13a5	tsweb: add FQDN to Port80Handler to allow HTTPS redirects When the request comes in say over http://mon, the current implementation would rewrite it https://mon which causes the cert validation to fail. This PR keeps the existing behavior intact but also allows passing in a FQDN to the handler to reroute to the correct hostname.

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

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

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.

Brad Fitzpatrick	2863e49db9	tsweb: don't flush, treat no-op Handler as 200, like Go Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
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
David Anderson	12a6626a94	tsweb: use a ResponseWriter wrapper to log more accurately. Also adds tests, because the logging handler is acquiring a fair number of branches. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago

David Anderson	98eceae55e	tsweb: add a Handler type. Handler is like http.Handler, but returns errors. ErrHandler converts back to an http.Handler, with added error handling and logging. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
Brad Fitzpatrick	5c1e443d34	wgengine/monitor: don't call LinkChange when interfaces look unchanged Basically, don't trust the OS-level link monitor to only tell you interesting things. Sanity check it. Also, move the interfaces package into the net directory now that we have it.	5 years ago
