Warp-only sync with warp-barrier [blocknumber] flag. #8228

tomusdrw · 2018-03-26T17:16:15Z

Enables warp-only sync in case --warp-after <block-number> is provided.

This allows the user to ignore old snapshots floating around and also makes sure that you are actually warp syncing.
After that block is reached we fall back to regular sync.

Resolves #8097

Moved that after the initial checks, otherwise in case we are not using warp-only sync, we might timeout a bit too early (I actually got a lot of peers on different chains from discovery), without even giving a chance to start warping.

folsen · 2018-03-27T08:35:52Z

LGTM, but I think we'll need some guidance on how to choose the block number. If people go on etherscan and pick the highest, they'll have to wait a long time until they find a snapshot for that, if they go back 100 blocks (1000 blocks?), they're more likely to find a snapshot quickly and can sync from there. Just a one-liner recommendation would be good.

5chdn · 2018-03-27T10:26:44Z

Can we just set a default to 5 million? This would partially address Fred's comment as users do not really need to care about this feature unless they really want to fine-tune parity.

jamesray1 · 2018-03-27T10:43:13Z

The problem with setting it to 5 million is that it will then gradually get longer to sync from there, so you'd have to manually update the default every so often. If you go back 5000 blocks that should be enough to guarantee that nearly all peers (except for those that don't take snapshots) would have taken a snapshot.

LGTM!

tomusdrw · 2018-03-27T11:48:43Z

@5chdn I'm more in favour of (optionally) storing network start date and average block time in the spec file and compute default value from this, at least it's always green.

tomusdrw · 2018-03-28T10:12:48Z

Voting for a better CLI name:

👍 --warp-at-least-to/--warp-to <bn>
😄 --warp-until <bn>
🎉 --warp-beyond <bn>
😕 --warp-after <bn>
❤️ --warp-barrier <bn>

--warp-barrier ❤️

--warp-threshold 👎

andresilva · 2018-03-28T10:20:38Z

I vote for --warp-to or --warp-until (I know these don't convey the meaning that the warp might actually be to after the given block).

jamesray1 · 2018-03-28T10:35:12Z

After that block is reached we fall back to regular sync.

This suggests that warp-at-least-to is most appropriate. I dislike relying on voting only as it encourages mob rule, I prefer rough consensus. If someone has a better reason to go with another option, I'm all ears.

Tbaut · 2018-03-28T10:58:06Z

👍 --warp-at-least-to/--warp-to <bn>
would be my favorit but is too long.. so I voted for
❤️ --warp-barrier <bn>

What about
--min-wrap-block ?

5chdn · 2018-03-28T11:40:07Z

@5chdn I'm more in favour of (optionally) storing network start date and average block time in the spec file and compute default value from this, at least it's always green.

Of course, this must be a chain-dependent default, so chain-spec is an idea.

jamesray1 · 2018-03-28T13:29:39Z

To convey the meaning more shortly than --warp-at-least-to there's --warp-to-min, or --warp2min if you want to be really lazy.

I compiled master this morning without problem, did you do rustup update then cargo clean && cargo build --release ?

andresilva · 2018-04-03T11:44:12Z

@jamesray1 Update your rust compiler to 1.25, since those methods on Duration were made const.

jamesray1 · 2018-04-03T12:04:26Z

OK, updated on my desktop, running cargo clean && cargo build --release now.

jamesray1 · 2018-04-03T12:05:08Z

On my laptop:

Sorry this is kind of basic, but is there a better way to update than uninstalling Rust then installing Rustup?

5chdn · 2018-04-03T12:05:57Z

Which rust version?

jamesray1 · 2018-04-03T12:08:25Z

rustc 1.22.1

jamesray1 · 2018-04-03T12:10:31Z

On the laptop, the first try included:

So I ran sudo apt-get install build-essential.

Then running cargo clean && cargo build --release again gave:

I think you're missing some dependencies, it's documented here: https://wiki.parity.io/Setup#dependencies.

apt-get install build-essential openssl libssl-dev libudev-dev

jamesray1 · 2018-04-03T13:35:19Z

@5chdn as explained above rustup update gives command not found. Also after running curl -sf -L https://static.rust-lang.org/rustup.sh | sh the version is still the same: 1.22.1.

jamesray1 · 2018-04-03T13:37:43Z

I'll try uninstalling Rust and reinstalling.

jamesray1 · 2018-04-03T13:54:06Z

I ran sudo /usr/local/lib/rustlib/uninstall.sh, and removing rustc, rustdoc and rust-gdb in /usr/bin but still I get:

Interestingly:

The program 'rustc' is currently not installed. You can install it by typing:
sudo apt install rustc

Please keep the Parity issue tracker on topic.

jamesray1 · 2018-04-03T23:07:24Z

Fixed: removed /usr/cargo/bin.

Overnight on the desktop, running ./target/release/parity --warp-barrier 5362706 (parity was on the old version, I've fixed that now) didn't work, it synced 1165 snapshots and has gone to #4263546, from #4255872.

Tbaut · 2018-04-04T07:16:07Z

5362706 is a bit optimistic. Could you share the logs (toward the end of the snapshot sync and the beginning of the blocks sync)?

5chdn · 2018-04-04T09:54:08Z

1155 snapshots take you directly to 5_370_000, just reset your db and try again

jamesray1 · 2018-04-05T01:26:42Z

Moving this to Gitter: https://gitter.im/paritytech/parity?at=5ac57b411130fe3d36a26b0a.

how do I reset the database? I searched on the wiki and looked at parity --help. Is there a way to reset it without deleting it?

Actually for the latest command I didn't set --log-file.
