Brad Fitzpatrick	1cb855fb36	util/expvarx: deflake TestSafeFuncHappyPath with synctest ... I probably could've deflaked this without synctest, but might as well use it now that Go 1.25 has it.

Brad Fitzpatrick	7c1d6e35a5	all: use Go 1.22 range-over-int ... Updates #11058 Change-Id: I35e7ef9b90e83cac04ca93fd964ad00ed5b48430 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2024-04-16 15:32:38 -07:00
James Tucker	0f3b2e7b86	util/expvarx: add a time and concurrency limiting expvar.Func wrapper ... expvarx.SafeFunc wraps an expvar.Func with a time limit. On reaching the time limit, calls to Value return nil, and no new concurrent calls to the underlying expvar.Func will be started until the call completes.
