How does the "--check-updates" parameter of monerod work?

Question

The monero daemon has this option:

  --check-updates arg (=notify)         Check for new versions of monero:
                                        [disabled|notify|download|update]

I tried running my node with --check-updates update, but no update/notification takes place.

$ ./monero-v0.10.2.1/monerod --check-updates update

status shows up to date.

Height: 1275771/1275771 (100.0%) on mainnet, not mining, net hash 57.12 MH/s, v4, up to date, 8(out)+21(in) connections, uptime 0d 23h 59m 3s

Is it implemented/working?

If yes, how does it work?

The --check-updates option has four subcommands:

update     subcommands: check (check if an update is available), download (download it if there is), update (not implemented)

check: check for updates, but do nothing beyond printing a notification
download: download any update
update: run the newly updated version

The last one is not implemented yet, only the first three are at the moment.

When you run status, the "up to date" comment does not refer to whether a new version is available: it relies on the timing of last known fork to determine whether there should be an update by the current time. It could be replaced with the new --check-updates method, now that it exists. Feel free to open a bug on https://github.com/monero-project/monero/issues mentioning that fact, and pros and cons may be discussed there.

so would you run --check updates download --check-updates update in order to downloads and run the update? Or would you run --check-update update to download and run? – Ginger Ale Mar 28 '17 at 22:09
@GingerA --check-update update will download new version first before update. – A.D. Mar 28 '17 at 23:31

You can run update check inside the daemon, and it should return you a status. If your daemon has a "no two valid DNS checkpoints" error, then the update command will not function properly, and you'll receive a msgwriter error.

I can partially answer my question because monerod meanwhile returned this:

[P2P5]  INFO    global  src/cryptonote_core/cryptonote_core.cpp:1121    Version 0.10.3.1 of monero for linux-x64 is available: https://downloads.getmonero.org/cli/monero-linux-x64-v0.10.3.1.tar.bz2, SHA256 hash 8db80f8cc4f80d4106db807432828df730a59eac78972ea81652aa6b9bac04ad
[P2P5]  INFO    global  src/cryptonote_core/cryptonote_core.cpp:1155    New version downloaded to "./monero-v0.10.2.1/monero-linux-x64-v0.10.3.1.tar.bz2"
[P2P5]  ERROR   updates src/cryptonote_core/cryptonote_core.cpp:1165    Download/update not implemented yet

The file exists so notification and download options are implemented.

status still shows "up to date".

On my second local node I'm receiving:

[P2P9]  WARN    net.dns src/common/dns_utils.cpp:529    WARNING: no two valid MoneroPulse DNS checkpoint records were received

And it's 1h 45m without any notify/download messages.

How does the "--check-updates" parameter of monerod work?
