[bfs]: cd .. does not work in deleted directory.

[emitrax]

Although not dangerous, this should behave differently.

mkdir temp
cd temp
rm -rf ../temp
cd ..

expected behavior: last command should correctly cd'us to the parent directory actual behavior: cd ../: no such file or directory error returned.

That doesn't appear to be BFS-specific, more likely the VFS. In any case, I see the same behavior on FreeBSD here, though not on Linux.

[emitrax]

I could only tested it in linux, and the behavior was like the one (I) expected. How BeOS behaves?

[bga]

I just tried this under Linux on an nfs mounted disk:

bga@librarian:~/x$ cd .. bash: cd: ..: No such file or directory

Behaves exactly like Haiku.

[anevilyak]

Hm..at least on Ubuntu with ReiserFS (all I have to test with Linux-wise) it works. FreeBSD concurs with your NFS experience though. It makes sense though, if you remove the directory then in theory the special files . and .. don't exist any more either.

[emitrax]

I have gentoo with ext3. This might then be fs specific, unless linux VFS have changed lately (kernel 2.6.20 over here). I can't try this on BeOS unfortuntely.

[bonefish]

BeOS reports the same error. Interestingly on Solaris (SunOS 5.10) I get:

bolero bonefish 5 (~/tt): rmdir ~/tt
rmdir: directory "/home/tfs/bonefish/tt": Can't remove current directory or ..

Though it can easily be tricked:

bolero bonefish 7 (~/tt): (cd ..; rmdir tt)
bolero bonefish 8 (~/tt): cd ..
-bash: cd: ..: No such file or directory

Haiku's behavior seem OK. Closing.
