RangeError: expected 50 to 50, found 0

[rajjeet]

Tried the following code:

from mgz import header, body
from os import fstat

with open('C:\\Users\\rajje\\PycharmProjects\\helloworld\\replay.aoe2record', 'rb') as data:
    eof = fstat(data.fileno()).st_size
    header.parse_stream(data)
    while data.tell() < eof:
        body.operation.parse_stream(data)

Go this error:

Hi, can you please provide the replay file? DE support is a bit rough right now since there is not a lot of sample data available.

I wanted to build an offline analytical tool, trying to parse the binary file.

[happyleavesaoc]

Thanks for the rec. I've replicated the issue. Something has recently changed in the DE rec structure. I will attempt to update the parser.

[happyleavesaoc]

I took a look at the rec. Player 2 is an AI, which changes how the initial struct is formatted (mgz/header/de.py). I attempted a few things to get it working, but there's more complexity than I have time right now.

Human-only recs are working (I fixed a few other issues as indicated in my previous response).

Also, do you have a DE replay that works with this parser? Thanks for this work btw.

Hi, can you please provide the replay file? DE support is a bit rough right now since there is not a lot of sample data available.

What kind of sample data would you prefer?

Also, do you have a DE replay that works with this parser? Thanks for this work btw.

This one can be parsed successfully. (only summary module, the parse_stream seems to have some problems right now)

MP Replay v101.101.34793.0 @2020.02.13 213505 (1).zip

[rajjeet]

@chesteripz With the MP replay I linked, I'm getting an error while trying parse the header or the body using the following code:

from mgz import header, body
from os import fstat

with open('./mp-replay.aoe2record', 'rb') as data:
    eof = fstat(data.fileno()).st_size
    header.parse_stream(data)
    while data.tell() < eof:
        body.operation.parse_stream(data)

I'm on python @3.6.2

[happyleavesaoc]

I'm tracking this issue. Thanks for reporting.

[happyleavesaoc]

@rajjeet Took a look at your rec, mp-replay.aoe2record. It's from an older version of DE. Commit 247c246a77a27e55d33990019e63b1da17c86105 can parse it. DE rec formats change somewhat frequently and this module isn't backwards compatible (theoretically it could be, but that's more work than I care to do). I expect the format to stabilize soon anyway. Also, FYI, that rec is an unranked lobby-hosted 3v3, not a ranked 1v1. Sorry you're having so much trouble getting this to work!

@chesteripz By sample data I just mean recs, ideally in bulk. The rec you posted should work with parse_stream , let me know what problem you're having.

[chesteripz]

When I try to use parse_stream, I've got the same error

never mind, I opened the older file

Closing. Feel free to re-open if you're still experiencing an issue.
