- Subject: Problem when HOME=/ [ncurses, less, .... ]
A number of programs are very slow or don't work when HOME=/
The problems can be traced to things like (e.g. when starting bash in a command
window)
482 144483 [main] bash 4448 normalize_posix_path: src //.terminfo/c/cygwin
or with less, which doesn't seem to work at all
48 10289507 [main] less 3464 normalize_posix_path: //.less =
normalize_posix_path (//.less)
The source lies in constructions such as printf ("%s/.less", HOME)
which create pathnames starting with // and thus interpreted as network
drives.
This also cause some kind of exception within Cygwin
415 6905204 [WNetGetResourceInformation] bash 4448 cygthread::stub: thread
'WNetGetResourceInformation', id 0x1520, stack_ptr 0x18DCEEF0
--- Process 4448, exception 000006BA at 7C81EB33
I can only suggest two possible fixes:
- ask all maintainers to check how HOME is used in their programs
- modify Cygwin to set HOME to '///' when it is '/'
This is ugly but will fix the problem for all programs, perhaps creating other
issues
