Honeybee Components Crash Rhino Immediately (Python uuid dependency seems suspect)

@Paul1 Okay is there a way I can have access to the machine (using TeamViewer) to test a few things out and maybe figure out the issue?

Yeah! If you have a TeamViewer license we may be able to. Perhaps Microsoft Teams could would work fine as well.

@eirannejad I’m having the same issues as @Paul1. Let me know if there is anything I can do to help the two of you troubleshoot this issue. Thanks

So just an update - IT added exceptions for the following folders and there was no change. Am I possibly missing a directory for the system libraries like rpcrt4.dll?

C:\Python27_64
C:\Program Files\IronPython 2.7
C:\Program Files\Rhino 6\Plugins\IronPython
C:\Users\username\ladybug_tools\python
C:\Users\username\AppData\Roaming\Grasshopper\

@alexchapin does your computer have SentinelOne for antivirus?

Another thread I found that might be of interest for this issue.

Thank you for sharing this other link and yes my computer uses SentinelOne for antivirus. Luckily I was finally able to solve my issue by having IT include the folder path for the Rhino.exe file in the exclusion list.

@alexchapin Thanks for reporting back. I’ll see if adding the Rhino folder works.

@eirannejad If IT whitelists the Rhino folder, that seems odd still in this sense that uuid.py couldn’t run correctly even in Powershell.

It’s possible that my issue was different from yours. I’m not sure. Hopefully my experience can help you though. Good luck.

Having IT add an exception for the Rhino folder allows uuid dependency to work again on that machine. Discussing it with IT, they also mentioned they modified a few overall settings in S1 to handle error suppression in a different way that doesn’t just ignore exceptions.

I´m having the very same issue

I confirm import UUID make Rhino crash if I create a separate gh component.

I´ running Version 6 SR33 (6.33.20343.16431, 08/12/2020)

IronPython - shall I update to a verison later than 2.7.8

@eirannejad I can´t find any Microsoft.Dynamic.dll if I search in the PC. The one on Rhino 6 it´s on my pc on the location above. I do not have Ironbug either.

How can I solve the issue?

Hi @Paul1 ,
I’m experiencing a similar issue.
Can you be more specific on what kind of overall settings your IT team did in the Sentinel one?

Hi, I had the same issue on Rhino 7 (IronPython,2.7.12.0,C:\Program Files\Rhino 7\Plug-ins\IronPython\IronPython.dll),

but not for Rhino 6 on the same machine (IronPython,2.7.8.0,C:\Program Files\Rhino 6\Plug-ins\IronPython\IronPython.dll)

But rather than trying to fix, I instead just did the following, which will work if you don’t need method1 uuid generation which relies on obtaining the MAC address of a machine.

Basically copy the UUID class from uuid.py along with the three mehods uuid3, 4 and 5 and the namespace constants. (NOTE: most implementations of uuid generation use method 4)

"""Provides a scripting component.
    Inputs:
        x: The x string to be hashed
        y: The y string to be namespaced (currently not an input as this hardcodes the standard DNS namespace into the def for uuid3 and 5)
    Output:
        guid3: Method 3 guid result
        guid5: Method 5 guid result
    Remarks:
        __author__ = 'Ka-Ping Yee <ping@zesty.ca>' a simplified version of the uuid library that solely depends on hashlib as other libraries were causing errors in IronPython grasshopper"""

    UUID objects are immutable, hashable, and usable as dictionary keys.
    Converting a UUID to a string with str() yields something in the form
    '12345678-1234-1234-1234-123456789abc'.  The UUID constructor accepts
    five possible forms: a similar string of hexadecimal digits, or a tuple
    of six integer fields (with 32-bit, 16-bit, 16-bit, 8-bit, 8-bit, and
    48-bit values respectively) as an argument named 'fields', or a string
    of 16 bytes (with all the integer fields in big-endian order) as an
    argument named 'bytes', or a string of 16 bytes (with the first three
    fields in little-endian order) as an argument named 'bytes_le', or a
    single 128-bit integer as an argument named 'int'.

    UUIDs have these read-only attributes:

        bytes       the UUID as a 16-byte string (containing the six
                    integer fields in big-endian byte order)

        fields      a tuple of the six integer fields of the UUID,
                    which are also available as six individual attributes

            time_mid                the next 16 bits of the UUID
            time_hi_version         the next 16 bits of the UUID
            clock_seq_hi_variant    the next 8 bits of the UUID
            clock_seq_low           the next 8 bits of the UUID

            clock_seq               the 14-bit sequence number

        hex         the UUID as a 32-character hexadecimal string
