toolchain: Some glibc change in getcwd between 2.3.6 and 2.4 has broken the feature series of CVS (1.12.*). Namely, getcwd does things with /proc/self/fd/%d/%s that return EACCESS.
yeah i highly doubt it much more likely the getcwd() implementation that cvs is bundling into itself via gnulib is broken if getcwd() were broken in glibc-2.4, a hell of a lot more things would be broken than just cvs try replacing lib/getcwd.c in cvs tarball with the latest one from gnulib
vapier, ok, I inspected gnulib's getcwd.c for changes - the only bits NOT in CVS's copy are: a fix for Solaris AT_FDCWD, a renaming of path* variables to be dir*, and some other cleanups that would run after the error we're hitting. I did however trace down what is different between glibc-2.4 and glibc-2.3. Namely glibc-2.4 has AT_FDCWD, and hits the first part of this structure, while glibc-2.3 doesn't, and avoids the open call, using lstat instead. #ifdef AT_FDCWD fd = openat (fd, "..", O_RDONLY); if (fd < 0) goto lose; fd_needs_closing = true; parent_status = fstat (fd, &st); #else dotlist[dotlen++] = '.'; dotlist[dotlen++] = '.'; dotlist[dotlen] = '\0'; parent_status = __lstat (dotlist, &st); #endif

openat is supposed to be manipulating paths via /proc/self/fd/#/.... as linux will handle the proper links back to the actual filesystem paths glibc-2.5 is in portage now ...
vapier: unless glibc-2.5 is likely to be stable soon, that isn't really a solution. could I undefine AT_FDCWD maybe as a workaround for this bug?
i meant glibc-2.5 is in portage so perhaps you should try upgrading and see if that fixes things ... if it does, we can look at backporting as for your question, no

Could someone try this patch and even if works including in a version bump of cvsd?
(In reply to comment #31) > Could someone try this patch and even if works including in a version bump of > cvsd? Seems to work fine for me, just remember that if you're running cvsd, you need to rebuild your root after you apply the patch and recompile cvs; otherwise, the binary in the cvsd won't contain the updated version and you'll probably have all sorts of problems.
(In reply to comment #31) > Could someone try this patch and even if works including in a version bump of > cvsd? > I can also affirm that this patch works. Thank you. On a side note, I applied this patch to cvs-1.12.12-r2 on an amd64 machine using the stable portage tree with glibc version 2.4 installed.
Created attachment 108317 [details, diff] Patch to fix cvs' internal getcwd Although the previous patch should work on most systems, this does not appear to be the cleanest solution for all systems: In fact, cvs intentionally provides its own variant of getcwd(), because apparently on some systems the systems' getcwd() might fail in some occasions. However, the getcwd() function of cvs also has a problem (see below), so probably the cleanest solution would be to *always* try the systems' getcwd() function and only use the internal function if the other fails - currently, the cvs-internal function is preferred if the system provides AT_FDCWD (which is the case on glibc systems). So, my first suggestion is to prefer the system's getcwd() even if AT_FDWCD is provided by the system. One problem of cvs internal getcwd() function occurs reproducible in directories which are subdirectories of a unionfs-mounted filesystem. For example, after mount -t unionfs -o dirs=/usr/portage/distfiles unionfs /root/tmp the cvs getcwd() function will fail in /root/tmp/cvs-src The reason is that the directory stream of /root/tmp gives a different inode number for the subdirectory cvs-src than an stat() of /root/tmp/cvs-src - only the latter is actually the correct inode number. However, to speed up things (i.e. to save the usage of stat()) cvs internal getcwd() function "believes" the former inode number so that it will never find the actual match. So, my second suggestion is - if the cvs-internal getcwd() function should be used - to never rely on the directory stream's inode (even if it is provided by most systems). This only slows down things slightly, but works much more reliable. The attached patch fixes both problems. Maybe these two problems should be reported upstream - they certainly fix a problem (at least that with unionfs, I do not know whether it solves the other poster's problems) and should not cause any incompatibilities except for a very mild slowdown of the internal getcwd() on some systems.
This bug still seems to exist. Is the attached patch supposed to be in portage? Thanks!
please retry with 1.12.12-r12
