Error about IMMUTABLE_BLOCKS

[ikolubr]

Hi guys, Getting this error while mining Litecoin/DOGE. It shows up, screws the hashing for some time then it goes away.

Unhandled Error

Thank you for supporting p2pool, Igor Almeida

This is on rawtx?

[ikolubr]

This is on rawtx?

Correct: On branch rawtx

Thank you,

[jtoomim]

Can you tell me what's on line 36 of your p2pool/networks/litecoin.py file?

Can you tell me the output of git status?

[ikolubr]

Line 36 of p2pool/networks/litecoin.py: BLOCK_MAX_WEIGHT = 4000000

Output of git status:

On branch rawtx

Oops, sorry. Line 38 of p2pool/networks/litecoin.py.

[jtoomim]

Also, git branch -v please.

[ikolubr]

A-ha! That is weird... line 36 was the last line of the file... so I went into the repo and checked the file, which has IMMUTABLE_BLOCKS = True in it. Mine, for whatever reason didn't!!! I added manually to see if the error doesn't show up.

Output of git branch -v before I manually added the line above:

master ece15b0 Merge pull request #65 from mansilladev/ismine-attr-fix
* rawtx  29fc6fc Stratum fixes:  - zero-pad extranonce1 and 2 to fix odd-length string issue;  - support extranonce1 (1 byte) to support Avalon 1246;  - use "null" instead of a random ID for pushed stratum messages (notify, set_difficulty)

Thank you

[ikolubr]

Fixed.
