198badafd8 pidof: size optimizations (-50 bytes) 2007-06-23 14:56:43 +00:00

459e4d6cf7 replace /proc scanning code by more versatile one.
Use it where appropriate.
Stop scanning /etc/passwd *for every process*!!! (uid->username)
top: reduce memory usage - we won't save unneeded fields
from /proc info anymore. Downside: ~+250 bytes of code

35fb512728 PID should be stored in pid_t, not int or long.
find_pid_by_name() was returning 0 or -1 in last array element,
but -1 was never checked. We can use just 0 intead.

56b217117a - add llist_free_one() and llist_free() to libbb; Add a bit of documentation.
- change llist_add_to_end as proposed by vodz in http://busybox.net/lists/busybox/2005-September/016411.html
- remove unneeded includes, add short boilerplate and copyright to llist.c
- move COMM_LEN from find_pid_by_name to libbb.h and use it in procps_status_t
- add reverse_pidlist() to find_pid_by_name. Will be needed for pidof.

I've reported this bug in April and it still
    exists in 1.00-pre2. So I made patches for
    both 0.60.x and 1.00-pre2.  The patch is very
    simple, just use strncmp instead of strcmp.
    Please apply if it is OK.

   Here's the procedure to test this problem:
   Create a executable with very long name, say
   'test_1234567890123456' and execute it. Try
   using 'killall' or 'pidof' to find/kill this
   program.  Without this patch, you can't find
   the program.

b24d65659f If find_pid_by_name() had an error, it was returning -1, but storing
that into a pid_t, which is unsigned on a number archs.  Furthermore,
find_pid_by_name() would _never_ return an error if the intended proces
was "init", but instead would return 1, meaning we would fail to work
on 2.4.x kernels running an initrd...
