24.1; dired-mark-sexp misparses directory contents |

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org. Please check that
the From: line contains a valid email address. After a delay of up
to one day, you should receive an acknowledgement at that address.
Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.
Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe
starting from `emacs -Q':
I recently wanted to mark all zero-size files in a dired buffer. I
found that dired-mark-sexp seemed to be just what I needed, but when I
invoked it with the _expression_ (= size 0), I found that it marked every
file, even those of nonzero size.
Here's a test directory I set up:
/home/mcafee/test:
total used in directory 28 available 102379756
drwxrwxr-x 2 mcafee mcafee 4096 Jan 27 18:31 .
drwxr-xr-x 44 mcafee mcafee 12288 Jan 27 18:31 ..
-rw-rw-r-- 1 mcafee mcafee 8 Jan 27 18:31 bar
-rw-rw-r-- 1 mcafee mcafee 12 Jan 27 18:31 baz
-rw-rw-r-- 1 mcafee mcafee 4 Jan 27 18:31 foo
In this directory, I ran dired-mark-sexp with the following _expression_,
intended to exercise all of the available symbols:
(progn (message "name=%s;inode=%s;s=%s;mode=%s;nlink=%s;uid=%s;gid=%s;size=%s;time=%s;sym=%s" name inodes mode nlink uid gid size time sym) nil)
Here are the messages that were produced:
name=.;inode=0;s=0;mode=drwxrwxr-x;nlink=2;uid=mcafee;gid=2;size=0;time= mcafee 4096 Jan 27 18:31;sym=
name=..;inode=0;s=0;mode=drwxr-xr-x;nlink=44;uid=mcafee;gid=44;size=0;time= mcafee 12288 Jan 27 18:31;sym=
name=bar;inode=0;s=0;mode=-rw-rw-r--;nlink=1;uid=mcafee;gid=1;size=0;time= mcafee 8 Jan 27 18:31;sym=
name=baz;inode=0;s=0;mode=-rw-rw-r--;nlink=1;uid=mcafee;gid=1;size=0;time= mcafee 12 Jan 27 18:31;sym=
name=foo;inode=0;s=0;mode=-rw-rw-r--;nlink=1;uid=mcafee;gid=1;size=0;time= mcafee 4 Jan 27 18:31;sym=
Clearly, the "time" variable includes more of the directory listing than
it should, and "size" is incorrectly set to zero for all files, as I
originally noticed.
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.

No complaints, so pushed.
For the record, the OP's example can easily be tested like this: Yank
the directory listing into some new buffer, load dired-x and call
virtual-dired. Then run dired-mark-sexp as described (but correct the
typo "inodes" to "inode s"). The relevant output in *Messages* is
name=.;inode=nil;s=nil;mode=drwxrwxr-x;nlink=2;uid=mcafee;gid=mcafee;size=4096;time=Jan
