Cardano Updates

implement transaction size estimation & revise existing tests

Try #1673:

Regenerate nix

Fixup: Label network magic NOTEs as FIXMEs

Explain rationale about the hard-coded TTL value

Fixup: make jormungandr compile again

Fixup: Use more ada in test to compensate for fee

Fix Matthias’ adjustments

Test that shelley tx estimateSize never underestimates

And tweak calculation

sort dependencies alphabetically in shelley .cabal

rewrite mkStdTx for readability & future maintenance

• split functions out so that they read better and will likely be re-used for implementing other parts of the transaction layer.
• avoid unnecessary identifiers declaration. Too many identifiers in a single small context don’t make things more readable.
• changed a few types to avoid repeating the same unwrapping operation
• named some in-place calculation (like realFee)
• used forM + pattern-matching instead of mapM and pointfree style. Pointfree is usually not readable when it’s in a context with more than one line

Introduce type ProtocolParameters.

Construct ApiNetworkParameters from NetworkParameters.

Adjust formatting to meet coding standards.

Regenerate nix

StartupSpec: Another attempt to fix the tests

StartupSpec: Fix the tests

Two things seem to make the tests flaky:

1. After the withPipe action finishes the file handles are closed. This causes hGetChar to throw an exception. It messes up the test result when the left-hand side of the withShutdownHandler race is still finishing.

2. If a hClose action is still in progress, it seems like it can end up executing the syscall after the next test case has started. The fd numbers are re-used, so it messes up the pipe for the next test case.

Fix tests and add invalid fd case

Make the clean shutdown handler simpler

This modifies the clean shutdown handler to use a FD from the command line, rather than taking stdin.

It also makes the logic even simpler, as shown in input-output-hk/cardano-node#767

The command-line arguments are changed from —shutdown-handler to —shutdown-ipc FD so that they are identical to cardano-node.

Construct ApiNetworkParameters from NetworkParameters.

Adjust formatting to meet coding standards.

Rename staticParameters to genesisParameters.

Rename genesisTxParameters to dummyTxParameters.

Rename genesisBlockParameters to dummyNetworkParameters.
