[issue44841] ZipInfo crashes on filemode

[Gabor Rakosy]

Gabor Rakosy  added the comment:

Like Ronald Oussoren wrote "ZipInfo does not have a filemode attribute, that's 
why it is not in ZipInfo.__slots__."


import zipfile

file_zip = zipfile.ZipFile("test-one-dir.zip", mode='r')
for info in file_zip.infolist():
print(info)
---

In the print, it shows the option 'filemode'. And that option is not 
accessible. That's the reason why i made this issue.

[issue44841] ZipInfo crashes on filemode

Ronald Oussoren  added the comment:

I'm not sure what the issue is here. ZipInfo does not have a filemode 
attribute, that's why it is not in ZipInfo.__slots__.

That said, it might be interesting to add a property to ZipInfo that extracts 
the file mode from ZipInfo.external_attr.

[issue44841] ZipInfo crashes on filemode

[Irit Katriel]

Irit Katriel  added the comment:

Crash typically means segfault or the like, not an exception. 

Can you provide code to create the file "test-one-dir.zip" so that we can 
reproduce the issue?
