Error: failed to fill whole buffer

[MAVProxyUser]

Same dataset as before... a few files trigger this error. Any idea what may cause it?

thread 'main' panicked at src/main.rs:46:45:

@MAVProxyUser, I've obtained the dataset but, could you indicate which log files are causing the crash?

I’ve been bulk processing them with the find command. I’ll see if I can augment it to print the file name:

find /path/to/dump/FlightLogs/ -type f -name '*.txt' -exec bash -c '
filepath="$1"
basepath="/path/to/dump/FlightLogs/"
relpath="${filepath#$basepath}"
dir="./ParsedLogs/$(dirname "$relpath")"
mkdir -p "$dir"
base="$dir/$(basename "${filepath%.txt}")"
mkdir -p "$base"
pushd "$base"
/path/to/dump/dji-log-parser/target/debug/dji-log-parser "$filepath" --images "image%d.jpeg" --output "records.json"
popd
' bash {} ;

Ok, this is an old log version 2 format that produces this error. The info section size is 350 bytes instead of 400.
I'll try to fix it tomorrow.

[lvauvillier]

Fixed. Thanks!

@MAVProxyUser can you share the rb files you mentioned (record_data_v1.rb, etc.)?
