RE: [Gnu-arch-users] tla1.2 on cygwin

[lode . leroy]

Path Compression is independent of cygwin, and of NTFS.

tla compiles without modification on cygwin, so no need to port it.

(Johannes Berg is porting tla/hackerlab to win32, which is a major
undertaking. I wrote a /hack/ to make tla work on a win32 system.
I worked on a similar /hack/ to use unicode pathnames with cygwin, but did
not finish it)

The only problem for using it on FAT is that tla depends on "inode"
values, and FAT does not have them, NTFS does have a similar thing.

Not realy, I don't even have a FAT partition.

To clarify for all: NTFS does support path lengths to 32000 chars, but
there's a catch.

On Windows, for each function, there is an ANSI version, and a Unicode
version. For example:
CreateFileA(char* path) and CreateFileW(w_char* path)
If one uses the CreateFileW() function, and the path starts with "\\?\"
then the path can be 32000 chars. If the path starts with something else
it is limited to 250 chars.

So most programs (being unaware of this) do not support long path names,
("most programs" include cmd.exe, explorer.exe, notepad.exe, gnuemacs.exe,
...)
