Hello,
Browsing web using eww and downloading compressed tar-files
(f.e. filename.tar.gz) save invalid files (can't be uncompressed).
I've tested on emacs 24.5 official packages both in Fedora 23 (x86_64)
and ArchLinux (x86_64 and arm), running with "emacs -Q -nw".
Tried also on git master, but download fails with this message:
error in process filter: Args out of range: #<buffer *http
pypi.python.org:443*>, 0, 13
To reproduce, browse to any web which offers any tar compressed file
and hit 'd' to download when cursor is over file URL. Then try to
uncompress it:
/home/inigo/Downloads ⚡ tar xvf filename.tar.gz
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Exiting with failure status due to previous errors
I see `eww-download` calls `url-retrieve` to download the file
asynchronously, which stores the downloaded file in an emacs buffer and
then saves it.
I think the problem comes from the buffer saving action and not from eww
code, but I don't have enough skills to debug this.
Btw, using `url-copy-file` (which does not employ an intermediate emacs
buffer) works ok, so I use this code:
(defun isr/eww-download ()
"Alternative not asynchronous download."
(interactive)
(let ((url (get-text-property (point) 'shr-url)))
(unless url
(message "No URL under point"))
(url-copy-file url (concat eww-download-directory "/"
(file-name-nondirectory url)))
(message "Saved %s" url)))
Thanks,
Iñigo Serna
PS: This is my first emacs bug report, excuse me if I've done something wrongly.
