FLIR GEV crash in _retrieve_file_path

[enp6s0]

Describe the Issue Cannot create acquirer with FLIR GEV cameras, apparently due to an option parsing error

To Reproduce Steps to reproduce the behavior:

1. Try to create an acquirer using the following code with FLIR GigE vision cameras

Sample Code I can show a piece of code that demonstrates the reported phenomenon:

• [X] Yes
• [ ] No

# Simplified version
h = Harvester()
h.add_file(cti) # cti points to actual GenTL producer under /opt/spinnaker
h.update()

acquirer = h.create({"serial_number" : "xxx"}) # seems to fail here
acquirer.start()

Traceback

Traceback (most recent call last):

    file_name, address, size = others.split(';')
ValueError: too many values to unpack (expected 3)

I've tried dumping out others, and it seems that the offending input is:

GRS_GEV_v003_189150.zip;7F1D0040;7959GRS_GEV_v003_181950.zip;7F1D0040;7959

Other inputs seems fine:

SFNC_GenTLSystem_Version_1_0_0_Schema_1_1.xml;42c1d80;74a3
SFNC_GenTLInterface_GigE_Version_1_0_0_Schema_1_1.xml;42c1d80;d58a

SFNC_GenTLInterface_Usb3_Version_1_0_0_Schema_1_1.xml;42c1d80;6867

Expected Behavior Harvesters should be able to connect to the camera and get image frames

Configuration

• OS: Ubuntu 22.04
• Python: 3.10
• Harvester: 1.4.2 (with patch from #421 applied to patch another startup crash)
• GenTL Producer: FLIR Spinnaker SDK 4.0.0.116
• Camera: Blackfly BFLY-PGE-05S2C, firmware v1.32.3.00

Reproducibility

This phenomenon can be stably reproduced:

• [X] Yes
• [ ] No.

Actions You Have Taken

• [X] I've read the Harvester FAQ page.
• [X] Dumping the others variable (see above) seems to reveal an offending input that contributed to the crash

[enp6s0]

As a workaround, I patched the parser to disregard extra parameters and trim the size variable... a hacky solution but it does work:

try:
    file_name, address, size = others.split(';')
except ValueError:
    splitted = others.split(';')
    file_name = splitted[0]
    address = splitted[1]
    size = splitted[2][:4]
