Is that a bug in bash or in cygwin, though? The comments for cygwin bash-2.05b-17 mention that a patch from Corinna Vinschen was applied to avoid turning '/' into '//' when converting/checking path. And `strace bash -c 'chdir //' shows: 32 20141553 [main] bash 1564 mount_info::conv_to_posix_path: // = conv_to_posix_path (//) 112 20141665 [main] bash 1564 chdir: dir '//' 29 20141694 [main] bash 1564 normalize_posix_path: src // 30 20141724 [main] bash 1564 normalize_posix_path: / = normalize_posix_path (//) 29 20141753 [main] bash 1564 mount_info::conv_to_win32_path: conv_to_win32_path (/) 32 20141785 [main] bash 1564 set_flags: flags: binary (0x2) 65 20141850 [main] bash 1564 mount_info::conv_to_win32_path: src_path /, dst c:\cygwin, flags 0xA, rc 0 89 20141939 [main] bash 1564 symlink_info::check: not a symlink 32 20141971 [main] bash 1564 symlink_info::check: 0 = symlink.check (c:\cygwin, 0x22E6D0) (0xA) 32 20142003 [main] bash 1564 path_conv::check: this->path(c:\cygwin), has_acls(1) 76 20142079 [main] bash 1564 chdir: 0 = chdir() cygheap->cwd.posix '/' native 'c:\cygwin' And this simple trace backs that up: $ cd // $ pwd // $ /bin/pwd / So it was the cygwin normalization code that turned '//' into '/', while bash thinks the current dir is '//'. What breaks if the cygwin chdir() normalization code is changed to not turn '//' into '/'? > Our track record for getting cygwin fixes into bash has been mixed. > I believe that someone has tried to get this fixed previously, along > with an even more serious problem with bash getting confused by > quick pid reuse but I believe that both problem still exist in > bash 3.0. Does bash 3.0 still have the bug that Corinna's patch to 2.05b fixed? At any rate, there is no official cygwin bash 3.0, because there has still been no volunteer to step up and produce a cygwin compilation of bash. - -- Life is short - so eat dessert first!
