/* This module's job is to
- convert between POSIX and Win32 style filenames,
- support the `mount' functionality,
- support symlinks for files and directories
2000-02-18 03:38:33 +08:00
Pathnames are handled as follows:
2000-02-18 03:38:33 +08:00
- A \ or : in a path denotes a pure windows spec.
- Paths beginning with // (or \\) are not translated (i.e. looked
up in the mount table) and are assumed to be UNC path names.
2000-02-18 03:38:33 +08:00
The goal in the above set of rules is to allow both POSIX and Win32
flavors of pathnames without either interfering. The rules are
intended to be as close to a superset of both as possible.
2000-02-18 03:38:33 +08:00
Note that you can have more than one path to a file. The mount
table is always prefered when translating Win32 paths to POSIX
paths. Win32 paths in mount table entries may be UNC paths or
standard Win32 paths starting with <drive-letter>:
2000-02-18 03:38:33 +08:00
Text vs Binary issues are not considered here in path style
decisions, although the appropriate flags are retrieved and
stored in various structures.
2000-02-18 03:38:33 +08:00
Removing mounted filesystem support would simplify things greatly,
but having it gives us a mechanism of treating disk that lives on a
UNIX machine as having UNIX semantics [it allows one to edit a text
file on that disk and not have cr's magically appear and perhaps
break apps running on UNIX boxes]. It also useful to be able to
layout a hierarchy without changing the underlying directories.
2000-02-18 03:38:33 +08:00
The semantics of mounting file systems is not intended to precisely
follow normal UNIX systems.
2000-02-18 03:38:33 +08:00
Each DOS drive is defined to have a current directory. Supporting
this would complicate things so for now things are defined so that
c: means c:\.

drive letter. These are not converted to NT native, but stored as
given. A path starting with a single backslash is relative to the
current drive thus a "relative" value (Flags == 1).
Funny enough it's possible to store paths with slashes instead of
backslashes, but they are evaluated incorrectly by subsequent Windows
calls like CreateFile (ERROR_INVALID_NAME). So, what we do here is to
take paths starting with slashes at face value, evaluating them as
Cygwin specific POSIX paths.
A path starting with two slashes(!) or backslashes is converted into an
NT UNC path. Unfortunately, in contrast to POSIX rules, paths starting
with three or more (back)slashes are also converted into UNC paths,
just incorrectly sticking to one redundant leading backslashe. We go
along with this behaviour to avoid scenarios in which native tools access
other files than Cygwin.
The above rules are used exactly the same way on Cygwin specific symlinks

Create native NT path here instead of calling path_conv. * mount.cc (find_root_from_cygwin_dll): Drop in favor of global initializaion in shared_info. (mount_info::init): Fetch native NT root dir from cygwin_shared. (mount_info::from_fstab): Expect native NT path and use native NT functions to access file. Convert username part in user fstab path according to special char transformation rules. * path.cc (tfx_chars): Convert slash to backslash. (transform_chars): Implement for path given as PWCHAR. (transform_chars): PUNICODE_STRING version calls PWCHAR version. Remove useless commented code.
