New submission from Enrico Zini <[email protected]>:
Hello,
this snippet does not work, because GzipFile wants a file-like object that can
do tell() and seek():
#!/usr/bin/python
import gzip
from urllib import urlopen
zfd = urlopen("http://ftp.debian.org/debian/dists/sid/Contents-udeb.gz";)
fd = gzip.GzipFile(fileobj=zfd, mode="r")
for line in fd:
foobar(line)
It must be possible to build a decompressing file-like object wrapper that can
do without seeking, since it is obviously not a limitation of gzip
decompression libraries. It would be extremely useful to have such a thing, as
shown in the example snippet above.
Some more details (including a very annoying misrepresentation of the issue
found in Dive Into Python) can be found at
http://www.enricozini.org/2011/cazzeggio/python-gzip/ (I apologise about the
ranting tone of the post).
