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 Anderson	eccae0cd0c	tsweb: add ReturnHandlerFunc. Signed-off-by: David Anderson <danderson@tailscale.com>	5 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	af3a9dfad6	tsweb: add a StdHandler that doesn't log 200 responses. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
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
Brad Fitzpatrick	6de37f4cc0	tsweb: move some comments, add a TODO	5 years ago
David Anderson	df4636567f	tsweb: adjust names and docs of the "handler with errors" functions. 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
Brad Fitzpatrick	a9cd8f31de	tsweb: don't double import expvar; appease staticcheck	5 years ago

David Anderson	d580157921	tsweb: quote label values to comply with Prometheus format.	5 years ago
David Anderson	f192c05413	metrics: add a LabelMap type for variables with 1 label dimension. This lets us publish sets of vars that are breakdowns along one dimension in a format that Prometheus and Grafana natively know how to do useful things with. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
Brad Fitzpatrick	e371520cc5	tsweb, derp: add expvar http.Handler for Prometheus's format And add some opinions. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
