Problems with MIST connecting to Parity in testnet

[johnwhitton]

Hi,

This is basically the same as https://github.com/ethcore/parity/issues/1161 which was closed and assumed fixed. Although I'm not sure what testing was done there. Please let me know if I can help in further testing You can find me on gitter

Today I did a fresh clone and build of parity and downloaded mist 0.7.4 again.
When trying to send transactions in testnet I get see attached
MistParityConnectionIssues.txt

ipcProviderBackend - IPCSOCKET 8 TIMEOUT ERROR
ipcProviderBackend - IPCSOCKET 8 ERROR { [Error: write EPIPE]

Note I am running parity using
a) parity --testnet --ipcpath ~/Library/Ethereum/geth.ipc
which places geth.ipc under /Users/johnwhitton/Library/Ethereum/
this is because if I run parity using
b) parity --testnet --geth
it places the geth.ipc file under
/Users/johnwhitton/Library/Ethereum/testnet
MIST always looks under /Users/johnwhitton/Library/Ethereum/ and so if run using a) it tries to open a second node.

This is a known issue documented here in geth ethereum/go-ethereum#2629

Here is the log from the new version with ipc chunking
Transactions are not being confirmed

what transaction fees are being paid? don't forget with the ether price being high, parity will default to a fairly low gasPrice, probably lower than the Geth miners are configured to accept. in any case, this is a separate bug - closing.

maybe related: #1265

[johnwhitton]

Bumping the GAS price, to fastest got the transaction picked up and processed. Thanks.

Ok to summarize it looks like there were three issues

1. Problem when reading contact code was the initial issue which is fixed under https://github.com/ethcore/parity/pull/1285/
2. Problem sending transactions which you can workaround by increasing the gas fee to faster and relates to https://github.com/ethcore/parity/issues/1265
3. There is an issue where I get an invalid json-rpc message when trying to send from the parity-ui. (I've created https://github.com/ethcore/parity/issues/1288 for this)

Thanks @NikVolf and @gavofyork for your work on this
