I am having issue with passing file-like object of a tgz file in Python. here is how my code looks like:
backup = tarfile.open(backup_file, mode='r:gz')
for f in backup.getmembers():
if f.name.endswith('.xml'):
ff = f.name
backupff = backup.extractfile(ff)
if backupff:
backupobj = backupff.read()
backup.close()
The problem arises from
backupobj = backupff.read()
and it gives this error:
AttributeError: 'bytes' object has no attribute 'read'
I don't have such a problem when dealing with zip files.
@AKX, you are right that this not the code I'm running. The real code are very big and I am not sure anyone has time to look into it.
Anyway, when I run the main function, I receive this error:
file_read = file.read
AttributeError: 'bytes' object has no attribute 'read'
Here is file.read part:
def sendfile(self, file, offset=0, count=None):
"""Borrowed from https://github.com/python/cpython/blob/3.6/Lib/socket.py
and adapted to our needs
"""
self._check_sendfile_params(file, offset, count)
if self.request.gettimeout() == 0:
raise ValueError("non-blocking sockets are not supported")
if offset:
file.seek(offset)
blocksize = min(count, 8192) if count else 8192
total_sent = 0
# localize variable access to minimize overhead
file_read = file.read
sock_send = self.request.send
I'm quite positive that's not the code you're running, or not the environment you're running in. I can't reproduce this with Python 3.8:
$ echo aaa > 1.xml
$ echo bbb > 2.xml
$ tar czvf a.tar.gz *.xml
a 1.xml
a 2.xml
$ cat x.py
import tarfile
backup_file = 'a.tar.gz'
with tarfile.open(backup_file, mode='r:gz') as backup:
for member in backup.getmembers():
if member.name.endswith('.xml'):
fh = backup.extractfile(member)
if fh:
content = fh.read()
print((member.name, content))
$ python3 x.py
('1.xml', b'aaa\n')
('2.xml', b'bbb\n')
I found the solution:
There is no need to use following commands:
if backupff:
backupobj = backupff.read()
This line is sufficient to assign the file to external user
backupff = backup.extractfile(ff)
