algod: Write to stdout when config.LogSizeLimit is 0 or -o is passed to algod. #3903

winder · 2022-04-21T12:12:15Z

Summary

Add an implicit option to write log to stdout by setting LogSizeLimit to 0.

Test Plan

Tested manually.

brianolson · 2022-04-21T12:49:59Z

I'm not sure what the prior behavior would have been with LogSizeLimit:0.
Would it be better anyway to have an explicit boolean --log-to-stdout ?
(But this change is clean if we decide to go this way)

What do you think about having both? The --log-to-stdout could overrides the LogSizeLimit variable.

The previous behavior here is basically a bug, all calls to log write an error to stdout:

Failed to write to log, CyclicFileWriter: input too long to write. Len = 273
Failed to write to log, CyclicFileWriter: input too long to write. Len = 415
Failed to write to log, CyclicFileWriter: input too long to write. Len = 273

I like the explicit option better. And yeah, it'd override because 'cyclic' doesn't make sense for stdout.

@brianolson added a flag. Also converted algod to use cobra, but I can revert that part.

Curious what the new algod -h looks like with cobra. Old for comparison:

$ algod -h
Usage of algod:
  -G    Print genesis ID
  -b    Display the git branch behind the build
  -c    Display and release channel behind the build
  -d string
        Root Algorand daemon data path
  -g string
        Genesis configuration file
  -l string
        Override config.EndpointAddress (REST listening address) with ip:port
  -p string
        Override phonebook with peer ip:port (or semicolon separated list: ip:port;ip:port;ip:port...)
  -s string
        Telemetry Session GUID to use
  -seed string
        input to math/rand.Seed()
  -t string
        Override telemetry setting if supported (Use "true", "false", "0" or "1"
  -v    Display and write current build version and exit
  -x    Initialize the ledger and exit

brianolson · 2022-04-21T14:32:00Z

cmd/algod/main.go

+	command.Flags().StringVarP(&args.listenIP, "listenIP", "l", "", "Override config.EndpointAddress (REST listening address) with ip:port")
+	command.Flags().StringVarP(&args.sessionGUID, "sessionGUID", "s", "", "Telemetry Session GUID to use")
+	command.Flags().StringVarP(&args.telemetryOverride, "telemetryOverride", "t", "", `Override telemetry setting if supported (Use "true", "false", "0" or "1"`)
+	command.Flags().StringVarP(&args.seed, "seed", "", "", "input to math/rand.Seed()")


I think this needs to respond to "-seed" to be compatible with flag. But every other flag option only had the natural single letter -x and fits with -x/--xtralongname

That might be a deal breaker here, that is the one part of the interface that had to change.

brianolson · 2022-04-21T14:35:34Z

daemon/algod/server.go

-	logWriter := logging.MakeCyclicFileWriter(liveLog, archive, cfg.LogSizeLimit, maxLogAge)
+
+	var logWriter io.Writer
+	if cfg.LogSizeLimit > 0 {


if args.logToStdout || cfg.LogSizeLimit <= 0 { ?

The main function overrides cfg.LogSizeLimit, so this is still the right condition.

This reverts commit 303231f.

I reverted the cobra changes, since you were curious this was the help output:

algod allows a node to participate in the agreement protocol, submit and confirm transactions, and view the state of the Algorand Ledger.

Usage:
  algod [flags]

Flags:
  -b, --branchCheck                Display the git branch behind the build
  -c, --channelCheck               Display and release channel behind the build
  -d, --dataDir string             Root Algorand daemon data path
  -g, --genesisFile string         Genesis configuration file
  -h, --help                       help for algod
  -x, --initAndExit                Initialize the ledger and exit
  -l, --listenIP string            Override config.EndpointAddress (REST listening address) with ip:port
  -o, --logToStdout                Write to stdout instead of node.log by overriding config.LogSizeLimit to 0
  -p, --peerOverride string        Override phonebook with peer ip:port (or semicolon separated list: ip:port;ip:port;ip:port...)
  -G, --printGenesis               Print genesis ID
      --seed string                input to math/rand.Seed()
  -s, --sessionGUID string         Telemetry Session GUID to use
  -t, --telemetryOverride string   Override telemetry setting if supported (Use "true", "false", "0" or "1"
  -v, --version                    Display and write current build version and exit

Oh, but now I'm imagining the convention -o foo to log to file foo and -o - for stdout.

doc would note "defaults to {data dir}/node.log"

I'd rather not add that feature unless there's a real reason that it would be useful. I kinda want to remove most of these flags, not sure they're actually used anymore.

I guess picking a different letter would address that concern but all the good letters are taken already.

Write to stdout when LogSizeLimit is 0.
