Different number of updates than with BGPKit-rust

[Aperence]

Hello,

I'm currently encountering a really weird issue. When trying to use this python library to parse a MRT file, I obtain different numbers of parsed Elem when using this library, or the original rust library.

Example on http://archive.routeviews.org/route-views4/bgpdata/2026.01/UPDATES/updates.20260101.1645.bz2:

use bgpkit_parser::BgpkitParser;

fn main(){
    let parser = BgpkitParser::new("http://archive.routeviews.org/route-views4/bgpdata/2026.01/UPDATES/updates.20260101.1645.bz2").unwrap();
    
    let mut count = 0;
    for elem in parser.into_iter(){
        count += 1
    }
    
    println!("{}", count);
    // Prints 484201
}

from pybgpkit_parser import Parser
parser = Parser("http://archive.routeviews.org/route-views4/bgpdata/2026.01/UPDATES/updates.20260101.1645.bz2")

count = 0
for elem in parser:
    count += 1

print(count)
# Prints 435264

However, it seems to me that those libraries should (in theory) be equivalent. Do you have any idea about the reason of those differences ?

Update: I've played a bit with the package by building it manually, and it seems that this issue is related to the bgpkit-parser version use by bgpkit-parser-py. There was perhaps a breaking change in bgkit-parser at some point ? When manually changing the version of bgpkit-parser to 0.14.0 in the Cargo.toml file, I obtain the same result (484201 elements) than with the rust library.

Suggested change: Update the version of bgpkit-parser to the latest version (0.14.0):

# Cargo.toml
- bgpkit-parser = "0.11.1"
+ bgpkit-parser = "0.14.0"
