test doc: tests `acceptstalefeeestimates` option is only supported on regtest chain

ismaelsadeeq commented at 10:15 pm on July 25, 2023: member

This PR Follow up comments from #27622

It test that the new regtest-only option acceptstalefeeestimates is not supported on main, signet and test chains, removes an unnecessary comment, and update fee estimator MAXFILEAGE description comment.

Due to the multiple datadirs in the feature_config_args test, this assertion actually does fail in combine_logs.py:

https://github.com/bitcoin/bitcoin/blob/db7120fbaddff6037734d8e42d1d002d773f8567/test/functional/combine_logs.py#L86

I get the same error on master branch too, so I dunno if it’s really up to you and this PR to patch around it or not.

You don’t need to clear here, or on L125 because you are opening the conf file with “w” so the contents of the file get overwritten. Tests pass without the two clear lines, and I checked with extra open/read/print statements that the expected configuration settings were present in the file at each step.

Can be made quite a bit more DRY:

0        self.log.info(f"Test -acceptstalefeeestimates option is not supported on non-regtest chains")
1        for chain in ["main", "test", "signet"]:
2            with open(inc_conf_file_path, 'w', encoding='utf-8') as conf:

Also don’t think this belongs in test_config_file_parser, probably worth adding its own function for?

Would generally avoid unrelated style nits, you’re not touching this line (or even file, for that matter) for anything else, so best to just leave as is.

glozow commented at 8:00 am on August 1, 2023:

I think I know what you mean, but imo transactions being stuck is a little bit of a jump from feerate underestimation. Maybe “Serving stale fee estimates may lead to overpaying in fees or not meeting minimum feerate requirements in the worst case.” Or just delete this comment, as the code is self-explanatory and there is already a comment above MAX_FILE_AGE.

jonatack commented at 10:13 pm on August 10, 2023:

I’m not sure why, and maybe it’s an issue with my local environment as the CI is green, but this test passes for me in the previous push 9bd96327232ac9fbb7f9cb0a0545a4410bdd4964 but not with the latest push ef19d52e25407df1a56a76038dd4c95e03e75250; only the signet case passes while the main and test cases raise the following:

0AssertionError: [node 0] Expected message "Error: acceptstalefeeestimates is not supported on test chain." does not fully match stderr:
1"Error: Unable to start HTTP server. See debug log for details."

jonatack commented at 10:40 pm on August 10, 2023:

Correcting myself, it turns out there isn’t a difference between the two pushes. The issue comes from having bitcoind already running on mainnet, testnet, or signet; if yes, the test fails with the message I described. If others see this issue too, would it be feasible to write the test to be independent of bitcoind running on those chains when the test is run?

ismaelsadeeq commented at 7:06 pm on August 14, 2023:

Thank you @jonatack, I was able to recreate the same Error. b24ffb05e42ec13ade193c9d7bea0def4296a4a8 should fix this.

jonatack commented at 10:14 pm on August 14, 2023:

Thanks for looking into it! Running the updated test with mainnet/testnet3/signet nodes running, the mainnet test passed. However, it still fails for the testnet3 and signet cases. (IDK about other people, but I usually have mainnet and one or both of signet and testnet3 running while working on this project and running tests.)

(nit in your last push, this diff was correct before the update, 2 spaces is the norm before a # comment)

0-            conf.write('')  # clear
1+            conf.write('') # clear

You can verify this using, say, the black python linter:

0$ black --code "conf.write('') # clear"
1conf.write("")  # clear
