Brad Fitzpatrick	d050700a3b	wgengine/magicsock: make peerMap also keyed by NodeID In prep for incremental netmap update plumbing (#1909), make peerMap also keyed by NodeID, as all the netmap node mutations passed around later will be keyed by NodeID. In the process, also: * add envknob.InDevMode, as a signal that we can panic more aggressively in unexpected cases. * pull two moderately large blocks of code in Conn.SetNetworkMap out into their own methods * convert a few more sets from maps to set.Set Updates #1909 Change-Id: I7acdd64452ba58e9d554140ee7a8760f9043f961 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Paul Scott	683ba62f3e	cmd/testwrapper: fix exit deflake (#9342 ) Sometimes `go test` would exit and close its stdout before we started reading it, and we would return that "file closed" error then forget to os.Exit(1). Fixed to prefer the go test subprocess error and exit regardless of the type of error. Fixes #9334 Signed-off-by: Paul Scott <paul@tailscale.com>	1 year ago
Brad Fitzpatrick	0396366aae	cmd/testwrapper/flakytest: don't spam stderr in Mark when not under wrapper If the user's running "go test" by hand, no need to spam stderr with the sentinel marker. It already calls t.Logf (which only gets output on actual failure, or verbose mode) which is enough to tell users it's known flaky. Stderr OTOH always prints out and is distracting to manual "go test" users.

Brad Fitzpatrick	dc7aa98b76	all: use set.Set consistently instead of map[T]struct{} I didn't clean up the more idiomatic map[T]bool with true values, at least yet. I just converted the relatively awkward struct{}-valued maps. Updates #cleanup Change-Id: I758abebd2bb1f64bc7a9d0f25c32298f4679c14f Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago

David Anderson	0909e90890	util/lru: replace container/list with a custom ring implementation pre-generics container/list is quite unpleasant to use, and the pointer manipulation operations for an LRU are simple enough to implement directly now that we have generic types. With this change, the LRU uses a ring (aka circularly linked list) rather than a simple doubly-linked list as its internals, because the ring makes list manipulation edge cases more regular: the only remaining edge case is the transition between 0 and 1 elements, rather than also having to deal specially with manipulating the first and last members of the list. While the primary purpose was improved readability of the code, as it turns out removing the indirection through an interface box also speeds up the LRU: │ before.txt │ after.txt │ │ sec/op │ sec/op vs base │ LRU-32 67.05n ± 2% 59.73n ± 2% -10.90% (p=0.000 n=20) │ before.txt │ after.txt │ │ B/op │ B/op vs base │ LRU-32 21.00 ± 0% 10.00 ± 0% -52.38% (p=0.000 n=20) │ before.txt │ after.txt │ │ allocs/op │ allocs/op vs base │ LRU-32 0.000 ± 0% 0.000 ± 0% ~ (p=1.000 n=20) ¹ Updates #cleanup Signed-off-by: David Anderson <danderson@tailscale.com>	1 year ago

Paul Scott	9a56184bef	cmd/tailscale: Check App Store tailscaled dialable before selecting. (#9234 ) PR #9217 attempted to fix the same issue, but suffered from not letting the user connect to non-oss tailscaled if something was listening on the socket, as the --socket flag doesn't let you select the mac apps. Rather than leave the user unable to choose, we keep the mac/socket preference order the same and check a bit harder whether the macsys version really is running. Now, we prefer the App Store Tailscale (even if it's Stopped) and you can use --socket to sswitch. But if you quit the App Store Tailscale, we'll try the socket without needing the flag.

Aaron Klotz	7d60c19d7d	clientupdate/distsign: add ability to validate a binary that is already located on disk Our build system caches files locally and only updates them when something changes. Since I need to integrate some distsign stuff into the build system to validate our Windows 7 MSIs, I want to be able to check the cached copy of a package before downloading a fresh copy from pkgs. If the signature changes, then obviously the local copy is outdated and we return an error, at which point we call Download to refresh the package.
