Subject: bug#9800: Incomplete truncated file buffers from the /proc filesystem
Date: Thu, 20 Oct 2011 01:59:42 +0300 [thread overview]
Message-ID: <877h40vb8h.fsf@mail.jurta.org> (raw)
Large files from the /proc filesystem are visited incompletely,
their file buffers are truncated at the position 65536.
One possible test case to reproduce this is to load enough libraries
with e.g. (imagemagick-register-types) and visit Emacs's maps file
in /proc/$PID/maps.
Andreas said in http://lists.gnu.org/archive/html/emacs-devel/2011-10/msg00782.html
that it's due to this code in `insert-file-contents':
/* The file size returned from stat may be zero, but data
may be readable nonetheless, for example when this is a
file in the /proc filesystem. */
if (end_offset == 0)
end_offset = READ_BUF_SIZE;
How this could be fixed? Should it keep reading while more data can be
read from the file?
