Logs to a txt or csv file missed some line for the last Test case

Hi Team,

I have a boofuzz script as below, log 3 type files: txt, csv and db.
def main():
fuzz_loggers = []
txt_log = open("/srv/boofuzz/http-fuzz-results.txt", "w")
fuzz_loggers.append(FuzzLoggerText(file_handle=txt_log))
csv_log = open("/srv/boofuzz/http-fuzz-results.csv", "w")
fuzz_loggers.append(FuzzLoggerCsv(file_handle=csv_log))

session = Session(
    target=Target(connection=TCPSocketConnection("192.168.1.1", 80)),
    fuzz_loggers=fuzz_loggers,
    keep_web_open=False,
    restart_threshold=5,
    db_filename="/srv/boofuzz/http-fuzz-results.db"
)

define_proto_static(session=session)
session.fuzz()

After scan finished, when I check the db file by "boo open...", and open the txt or csv files, I found that there are some lines missed in txt and csv files compared with the GUI for the last case.

Here is the result from GUI for the last case:

Here is the txt log file for the last case:

Expected behavior

The "Check OK: No crash detected." and other lines are contained in txt&csv files for the last case.

Actual behavior

The "Check OK: No crash detected." and other lines are missed in txt&csv files for the last case.

Steps to reproduce the problem

1. Just run the boofuzz script as above
2. Use "boo open..." to check the result
3. Open the txt log file, compared with GUI result, missed some lines

boofuzz script

def main():
    fuzz_loggers = []
    txt_log = open("/srv/boofuzz/http-fuzz-results.txt", "w")
    fuzz_loggers.append(FuzzLoggerText(file_handle=txt_log))
    csv_log = open("/srv/boofuzz/http-fuzz-results.csv", "w")
    fuzz_loggers.append(FuzzLoggerCsv(file_handle=csv_log))

    session = Session(
        target=Target(connection=TCPSocketConnection("192.168.1.1", 80)),
        fuzz_loggers=fuzz_loggers,
        keep_web_open=False,
        restart_threshold=5,
        db_filename="/srv/boofuzz/http-fuzz-results.db"
    )

    define_proto_static(session=session)
    session.fuzz()

    session.connect(s_get("Request"))

Thanks for the bug report @vincentwh2018 ! I bet there's an inconsistency somewhere in one of the log classes.

Long time since I had the time to contribute to boofuzz. I have reproduce the issue using the example. Next I will try to determine the root cause.

[ptdropper]

Root cause found and corrected. I will create a pull request.
