--- Begin Message ---Package: fakechroot Version: 2.5-1.1 Severity: important Inside fakechroot, make displays make[1]: Entering directory `/home/eichin/....' ie. it display the *outside* path. Yet a Makefile target running pwd gives the correct value. (I was hunting this down in search of another problem...) Turns out that this is a fakeroot bug. getcwd is documented in getcwd(3) as: The getcwd() function copies an absolute pathname of the current work- ing directory to the array pointed to by buf, which is of length size. Note that further on, the man page only suggests the return value as having meaning in two cases: it's NULL if the call can't fit the path in the buffer, and a linux-specific hack of having getcwd malloc() the value if buf is NULL. gnu make, being quite portable code, simply calls: if (getcwd (current_directory, GET_PATH_MAX) == 0) and expects current_directory to have the desired value. fakechroot-2.5/src/libfakechroot.c #define narrow_chroot_path, in the typical ("not in /") case, does this: (path) = ((path) + strlen(fakechroot_path)); \ ie. returns a pointer that skips over the prefix. "That's Not Right" :-) The obvious fix is to do something like memmove(path, path+strlen(fakechroot_path), 1+strlen(path)-strlen(fakechroot_path)) instead, though I have not tested this. I've also noted that bash uses the "return value ignored" form in the only two places it actually calls the function, so builtins probably have buggy behaviour here too: ./parse.y:4146: if (getcwd (t_string, sizeof(t_string)) == 0) ./jobs.c:355: dir = getcwd (d, sizeof(d)); if (dir) dir = d; (I went digging for this in search of an explanation for a /bin/sh: line 1: cd: .: No such file or directory message from deep in a fakeroot/fakechroot/pdebuild/pbuilder/dpkg-buildpackage stack, and will see if this helps shortly... but since it's clearly wrong even if it doesn't, I figured I'd get the bug report out the door promptly.) -- System Information: Debian Release: 4.0 APT prefers testing APT policy: (500, 'testing'), (500, 'stable') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.14.1manekineko Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) Versions of packages fakechroot depends on: ii libc6 2.3.6.ds1-8 GNU C Library: Shared libraries fakechroot recommends no packages. -- no debconf information
