Package: procps Version: 1:3.3.3-3 Severity: normal What I do:
I type "pwdx $$". What I expect to happen: I expect pwdx to print the current working directory of my shell. What actually happens: pwdx prints a message such as the following: pwdx: invalid process id: 18110 The number is variable; it depends on the value of $$, of course; but the remainder of the message is always the same. Further details: I make use of two PCs. The above problem occurs on one of them (named albatross, the PC from which I am making this bug report), but not on the other. Solution: I looked at the source code of pwdx, specifically, at the file pwdx.c in the Debian source package. It is clear that there is a bug in the function check_pid_argument. That function calls strtol, in order to check that a certain string is a valid integer. It then checks the value of errno. I have determined that, on albatross, errno has the value 2 before the call to strtol. Therefore, the check of errno that follows the call to strtol concludes, mistakenly, that the string is not a positive integer. The fix for this is given in the man page for strtol. To quote: the calling program should set errno to 0 before the call, and then determine if an error occurred by checking whether errno has a nonzero value after the call. -- System Information: Debian Release: 7.4 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.2.0-4-amd64 (SMP w/2 CPU cores) Locale: LANG=en_IE.UTF-8, LC_CTYPE=en_IE.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_IE.UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages procps depends on: ii initscripts 2.88dsf-41+deb7u1 ii libc6 2.13-38+deb7u1 ii libncurses5 5.9-10 ii libncursesw5 5.9-10 ii libprocps0 1:3.3.3-3 ii libtinfo5 5.9-10 ii lsb-base 4.1+Debian8+deb7u1 Versions of packages procps recommends: ii psmisc 22.19-1+deb7u1 procps suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
