Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago
Anton Tolchanov	f053f16460	tsweb: export version metrics to Prometheus This will allow tracking build versions and runtime versions in Prometheus. Signed-off-by: Anton Tolchanov <anton@tailscale.com>	1 year ago

Anton Tolchanov	3c27632ffe	tsweb: avoid dashes in Prometheus metric names Ideally we should strip other invalid characters too, but that would call for a regexp replacement which increases the number of allocations and makes `TestVarzHandlerSorting` fail.

Brad Fitzpatrick	614a24763b	tsweb: sort top-level expvars after removing type prefixes Fixes #5778 Change-Id: I56c367338fa5686da288cc6545209ef4d6b88549 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	718914b697	tsweb: remove allocs introduced by earlier change This removes the ~9 allocs added by #5869, while still keeping struct fields sorted (the previous commit's tests still pass). And add a test to lock it in that this shouldn't allocate. Updates #5778 Change-Id: I4c12b9e2a1334adc1ea5aba1777681cb9fc18fbf Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Hasnain Lakhani	8fe04b035c	tsweb: sort varz by name after stripping prefix (#5778 ) This makes it easier to view prometheus metrics. Added a test case which demonstrates the new behavior - the test initially failed as the output was ordered in the same order as the fields were declared in the struct (i.e. foo_a, bar_a, foo_b, bar_b). For that reason, I also had to change an existing test case to sort the fields in the new expected order. Signed-off-by: Hasnain Lakhani <m.hasnain.lakhani@gmail.com>	2 years ago
Will Norris	62bc1052a2	tsweb: allow HTTPError to unwrap errors Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Mihai Parparita	c66e15772f	tsweb: consider 304s as successful for quiet logging Static resource handlers will generate lots of 304s, which are effectively successful responses. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Denton Gentry	755396d6fe	tsweb: add Float expvar support in varz We make assertions about stringification of 0.5. IEEE floating point and all reasonable proprietary floating point can exactly represent 0.5. We don't make assertions about other floating point values, too brittle in tests.

Brad Fitzpatrick	0df3b76c25	tsweb: fix Port80Handler redirect to https with FQDN unset Fixes the current http://pkgs.tailscale.com/ redirect to https:/// as that server doesn't configure the Port80Handler.FQDN field.

Brad Fitzpatrick	2d1849a7b9	tsweb: remove JSONHandlerFunc It's unused and we've decided it's not what we want. Change-Id: I425a0104e8869630b498a0adfd0f455876d6f92b Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
David Anderson	7b4960316b	tsweb: add PrometheusVar, for vars that want to output varz themselves. This enables the infrequent use of more complex Prometheus types, such as timeseries with high/irregular label cardinality, without needing to discover and implement generic abstracted type like LabelMap for each one.

Brad Fitzpatrick	5aba620fb9	tsweb: make VarzHandler capable of walking structs with reflect To be used by control, per linked bug's plan. Updates #2635 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

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

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	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>	4 years ago
