Hi all

I built a Python wrapper for the Intercall library to access an Universe database.

Now I'm porting my utilities so they can use the native uopy module. The work is pretty straightforward but I don't find the equivalent call to ic_fileinfo

ic_fileinfo (key, file_id, data, buffer, buffer_size, code)

Is there a way to do this using pure uopy calls or do I have to build a custom UniRPCPacket to simulate the Intercall function?

Hector,

Adding FILEINFO() functionality native to U2 Python is currently being considered as an addition. It is worth opening a support ticket through your normal channels to add yourself to the requestors for this so you get updated as and when the request status changes. Alternatively, please monitor the >>Product Availability Matrix (PAM)<< for future release notices and any announcements.

Currently I suspect you would need to work indirectly in this by calling a BASIC subroutine with a file name or path as an input argument. Once the BASIC code has retrieved the data (and closed the file) it can pass back the results in the return arguments.

Hopefully this helps.

Hector, fileinfo() is available in u2py in UniData 8.2.2 and above.

Hector,

Just cross-checking - not yet in 12.x. but in 11.3.2

UNV-27537 Before this release, only the BASIC FILEINFO function provided a lot of information about an open file, but u2py did not provide a way to achieve this. Now, the u2py.File.fileinfo function can provide a lot of information about an open file.

As previously mentioned, uopy does not have a fileinfo method at this time. There is a request in Engineering to add something similar to what was done in u2py.

The following is a quick overview on how the u2py.File.fileinfo function works:

u2py.File.fileinfo

The u2py File object now has a fileinfo function that is used to get more information on the u2py.File object opened in your Python program.

# For this example we need to change the working directory to the XDEMO account
import os
os.chdir("..")
print(os.getcwd())
import u2py
help(u2py.File.fileinfo)

Help on method_descriptor:

fileinfo(...)
    F.fileinfo(key) -> int or enum value defined in u2py.py -- return information about the specified file’s configuration, 
    
    such as the specified file’s parameters, its modulus and load, its operating system file name, and its VOC name.The information returned depends on the file type and the value of the key.

First you will need to instantiate a u2py.File object

voc = u2py.File("VOC")
a = voc.fileinfo(2)
print(str(a))

C:U2ud822XDEMOVOC

Note that in the above I passed a 2 to the function which returned the file path.  Note that there are several
enumerated parameters that you can use to get information on the file:

You can use either the name or the number

print(voc.fileinfo(2))
print(voc.fileinfo(u2py.FINFO.PATHNAME))
