Brad Fitzpatrick	49a3fcae78	log/filelogger: make filelogger remove redundant date before adding a date ... At some point since filelogger was added on Windows, the log hierarchy above it changed such that a log.Printf writes to filelogger and includes the log package's own date. But then filelogger adds another. Rather than debug everything above and risk removing the prefix when run by tailscaled, instead just remove the log package's prefix very late right before we go to add the filelogger's own.

Denton Gentry	280c84e46a	ipn/ipnserver, paths, logpolicy: move Window config files out of %LocalAppData% ... C:\WINDOWS\system32\config\systemprofile\AppData\Local\ is frequently cleared for almost any reason: Windows updates, System Restore, even various System Cleaner utilities. The server-state.conf file in AppData\Local could be deleted at any time, which would break login until the node is removed from the Admin Panel allowing it to create a new key. Carefully copy any AppData state to ProgramData at startup. If copying the state fails, continue to use AppData so at least there will be connectivity. If there is no state, use ProgramData. We also migrate the log.conf file. Very old versions of Tailscale named the EXE tailscale-ipn, so the log conf was tailscale-ipn.log.conf and more recent versions preserved this filename and cmdName in logs. In this migration we always update the filename to c:\ProgramData\Tailscale\tailscaled.log.conf Updates https://github.com/tailscale/tailscale/issues/2856 Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
Brad Fitzpatrick	420838f90e	log/filelogger: move our Windows disk file writing+rotation package here ... It's still Windows-only for now but it's easy to de-Windows-ify when needed. Moving it out of corp repo and into tailscale/tailscale so we can use it in ipnserver.BabysitProc. Updates #726	4 years ago
Emmanuel T Odeke	688f923db1	log/logheap: properly document LogHeap as performing HTTP upload (#741) ... LogHeap no longer logs to os.Stderr and instead uploads the heap profile by means of an HTTP POST request to the target URL endpoint. While here, also ensured that an error from pprof.WriteHeapProfile isn't ignored and will prevent the HTTP request from being made if non-nil.
