Suppose a.zip is z zip file containing 'abc/def/1.txt'
zf = zipfile.ZipFile('a.zip')
memf = zf.open('abc/def/1.txt', 'r')
zf2 = zipfile.ZipFile(memf)
will raise an error. However, when a.zip is a tar file containing 'abc/def/1.txt', the following codes
tf = tarfile.open('a.zip')
memf = tf.open('abc/def/1.txt', 'r')
zf2 = zipfile.ZipFile(memf)
works well. Is it a known issue?
Thanks!

The current behavior looks correct to me. abc/def/1.txt is not a ZIP file, so the error is expected.
tarfile.open('a.zip') raises an error too, because a.zip is not a tar file.

Sorry, I made a mistake. I retested on the following content
a.zip ==> abc/def/1.zip
zf = zipfile.ZipFile('a.zip')
memf = zf.open('abc/def/1.zip', 'r')
zf2 = zipfile.ZipFile(memf)
will raise an error. However, when a.zip is a tar file containing 'abc/def/1.zip', the following codes
a.tar ===> abc/def/1.zip
tf = tarfile.open('a.tar')
memf = tf.extractfile('abc/def/1.zip')
zf2 = zipfile.ZipFile(memf)
works well.
Since only one file can be uploaded, I will try to upload the tar file on the next post.

Supporting nested zip files is a new feature added in 3.7 (see issue22908). New features can be added only in new Python versions. 3.6 currently takes only security bug fixes. |
