rubocop displays 1265 offenses from all over the project, so not sure what to do about it

FrancisMurilloDigix · 2019-09-04T02:41:46Z

@bshevchenko Don't worry about the warnings. We are using rubocop as the formatter, not a linter.

FrancisMurilloDigix · 2019-09-04T13:08:22Z

Can you run rubocop -a and only commit the files for this PR? In my editor, I usually have the files I touched autoformat with rubocop.

bshevchenko · 2019-09-04T13:28:43Z

@FrancisMurilloDigix done! Draft code for cron job is within the watching_transaction module (resend). Need your feedback on it. Job itself should be configured depending on the server environment, which I am not aware of.

Btw, as far as I am concerned, @roynalnaruto is supposed to be the reviewer for this PR, no?

FrancisMurilloDigix · 2019-09-04T13:42:21Z

@bshevchenko I am the main developer for the Rails application so I am also the reviewer. For the cron job, checkout scheduler.rb.

bshevchenko · 2019-09-04T13:46:11Z

@FrancisMurilloDigix all right, thank you! So shall I just put my code there under the "schedule.every '5m' do"?
Also what do you think on web3 initialization in the watching_transaction.rb? And on test coverage for resend method. I didn't test it yet, neither manually or automatically.

FrancisMurilloDigix · 2019-09-04T13:55:31Z

@bshevchenko 5m is fine.

Was going to comment whether we can remove the web3 dependency and simply put it in ethereum_api.rb.

So, as of now, I see 6 unresolved conversations that are related to:

Tests for WatchingTransaction model (watch, resend, resend_transactions)
Having transactionHash outside of the transactionObject argument

On 1 I'll soon provide new commits, but for 2 I need more feedback

FrancisMurilloDigix

For 2, you are right about the receipt and txhash so we have to take the extra txhash field for watchTransaction.

bshevchenko · 2019-09-10T19:39:53Z

@FrancisMurilloDigix check out my latest commit please

bshevchenko · 2019-09-10T19:43:09Z

@FrancisMurilloDigix or even 3 latest commits. They include what was lacking. I hope that's all

FrancisMurilloDigix

Almost there.

@FrancisMurilloDigix everything seems to be resolved to me

FrancisMurilloDigix

Pretty pleased with this.

Just some enhancements on the test and one forgotten test on the WatchedTransaction

@FrancisMurilloDigix check latests commits please

FrancisMurilloDigix

Nicely done. When you're done addressing this last touch up.

Do rubocop -a and commit the files again.
Do squash the commits

Can you use size instead of 1 here?

It's supposed to be 1, because if API is unavailable then no more attempts will be made during current job

Actually it is called for each transaction so it is n times instead of 1. You should try setting it to n and then n+1 to see the effect.

No, it breaks whole cycle. Tests are passing

You missed few new lines in watching_transaction.rb:
if ok_tx == :error
Rails.logger.info 'Failed to get transaction by hash. Killing job..'
break
end

@FrancisMurilloDigix I'm not getting what you trying to say

It'll anyway break on the next iteration

if API would be still unavailable

Even if the next iteration fails and the reason is that the API is down or a network issue, then returning or breaking early is fine. Since error handling is not truly addressed, at least the consistency of behavior is the same when either request is down.

Yeah, so adding a break or return on a failed send_raw_transaction is good enough for now.

Nicely done. When you're done addressing this last touch up.

Do rubocop -a and commit the files again.

Do squash the commits

All right, but I'm curious why you don't just use "Squash and merge" feature?

bshevchenko · 2019-09-12T07:55:40Z

@FrancisMurilloDigix done

FrancisMurilloDigix · 2019-09-12T21:21:51Z

Thanks for your hard work. Will merge after some advice from @tymat

Will add the remaining break and rubocop -a everything so the formatter just works hopefully.
