[Pkg-mc-devel] [Bug 661959] [NEW] Incorrect expansion of '~' on Esc-Tab

[Ben Okopnik]

Public bug reported:

Binary package hint: mc

$ mc -V
GNU Midnight Commander 4.6.2
Virtual File System: tarfs, extfs, cpiofs, ftpfs, fish
With builtin Editor
Using system-installed S-Lang library with terminfo database
With subshell support as default
With support for background operations
With mouse support on xterm and Linux console
With internationalization support
With multiple codepages support
Data types: char 8 int 32 long 32 void * 32 off_t 64 ecs_char 8

Background: 'mc' expands partially-typed command names and
file/directory names on the command line when the 'Esc-Tab' combination
is pressed (e.g., "ls /usr/local/b<Esc><Tab>" either expands to a
matching file or directory in /usr/local if there's only a single
possible match, or shows a pick list of all matching files/directories.)

Problem: If the path to be expanded begins with "~", the expansion -
both as a single entry or in the pick list - begins with '\~/', which is
not the correct file/directory name for the specified string.

Unfortunately, I'm not much good at hacking C any more, but it seems as
though the problem would be in src/utilunix.c , in the tilde_expand ()
subroutine.
