Date: Sat, 28 Feb 2015 00:59:20 -0800

(coreutils-8.21-7.7.7)

wc -c(bytes) doesn't seem to reliably read the number
of bytes in a file.

I was wanting to find out what the largest data-source
files in '/proc' and '/sys' (didn't get around to trying
/sys, since all the files under /proc/sys return 0 bytes.

Note -- "wc -l" doesn't return '0' on the /proc/sys files.

As root:
# cd /proc
# find -H [^0-9]* -name self -prune -o -name thread-self -prune -o -type 
f ! -name kmsg ! -name kcore ! -name kpagecount ! -name kpageflags 
-print0|wc -c --files0-from=- |sort -n

Thanks for the report.
However, I'm not 100% sure what the problem is - as you didn't narrow
the case down to a certain file, nor did you show us the output and
what you expected.

A quick shot is
  http://bugs.gnu.org/18621
and the corresponding commit (after the latest v8.23 release)
  http://git.sv.gnu.org/cgit/coreutils.git/commit/?id=2662702b

Does this - i.e., a wc(1) built from git - solve your problem?

Thanks & have a nice day,
Berny

	Yes.   I did.  Anything under /proc/sys is affected.
There is more than 1 'certain file' that is affected.

	What I would _expect_ is for it to show the actual # of bytes
in the file rather than a size of 0.

	That's why I included the command to duplicate the problem.
Are you saying you tried it and it doesn't do the same thing on
your system?

	Without me debugging the source, how much more do you
want me to narrow it down?  If you change the "wc -c" => "wc "-l",
you will see non-zero numbers for files under /sys/proc.

	BTW .. it seems many files under /sys are also affected.

----
	As for files under /proc, the 'net' directory seems to work:
Are you wanting a list like this:
Ishtar:/proc> find -H sys net -name self -prune -o -name thread-self -prune -o -type f ! -name kmsg ! -name kcore ! -name kpagecount ! -name kpageflags -print0|wc -c --files0-from=- |sort -n

Sorry to be unclear, but I would expect the numbers under /proc/sys
to look something like the numbers under /proc/net.

FWIW, the 'prune' and exceptions in the find are to filter
out some degenerate cases (like byte counts in /proc/kmem)
as well as too much verbosity (skip the processes, including self and 
thread-self).  I also used the -H switch to not skip initial symlinks,
but ignore lower ones.

For the numbers under /sys, most seem to return a wrong size.a size of 0, but 
doing a 'cat FILENAME|wc -c' shows the correct number.

I didn't give much data about /sys, as getting a test case that 
would run just for /proc, w/o hanging or looping took too long
(like trying to read 'kmsg' takes forever and will basically
hang the test case).

	Certainly looks like what I'm seeing.  HOWEVER, 
why do I get numbers in "/proc/net" but not under "/sys"?

	Seems like there is something else going on here.

	It may work *around* the problem, but doesn't explain
the inconsistencies between, for example, /proc/sys and /proc/net.
If the patch forces a read, there's a good chance it will work, but
the inconsistent returns from /proc/sys, /proc/net AND /sys(seems
to often show 4K as noted in the other bug report), would seem
to indicted a kernel bug somewhere.  If they were ALL 0 or all 4K,
then I'd say the kernel doesn't return size for either of those
interfaces (and that may be as far as that goes and the workaround
is the only solution), but that the kernel interfaces are giving 
back inconsistent answers seems like different users not using
the same kernel interfaces to return the 'inode' size.

	Did this provide enough info?

	Am a bit leery of trying a new version of core utils on
short notice as I need to make sure new breakages having occurred in
other utils and w/my luck, I might accidently install the newer
version over a working version (Murphy** visits, here, often).

**-as in Murphy's Law..

Cheers!

The Linux kernel is notoriously bad about advertising 0-length file size
for non-empty contents of files within sysfs and procfs.  Any program
that trusts just stat() output will report 0; the only way to see
non-zero sizes on these special files is to open() and read() them (I'm
not even sure if lseek(SEEK_END) does the trick) - but fixing that is
something for the kernel folks to do, and not coreutils to work around,
because it is more than coreutils that is affected by the kernel's lies.

to be fair, for some pseudo files, it's not feasible or possible to report the 
real size

`wc -c < /proc/file` should work

Thanks for the report.
However, with wc from coreutils-8.23 and a 3.10 kernel, this is no
longer an issue.

with coreutils 8.23 from suse 13.2 and uname:

Linux Ishtar 3.18.5-Isht-Van #1 SMP PREEMPT Wed Feb 4 14:50:44 PST 2015 x86_64 x86_64 x86_64 GNU/Linux

it is an issue.  All the "/proc/sys" entries are still 0.

Here's the output (with a some lines elided)...

The issue will be addressed in 8.24:
http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=v8.23-47-g2662702

You can build this locally and test just with the src/wc binary
without worrying about overwriting any packaged binaries.

Correction: I was using wc from upstream git (coreutils-8.23.141), so as
Pádraig says, it will be fixed in 8.24.
