cant access to files more than 128 utf-8 symbol long names

Tue Dec 10 07:16:00 GMT 2013

Hello!

When using cygwin, i can't list, copy, remove files and directories with 
128 utf-8 symbol long names.

useless examples that illustrates the problem:

it is OK with latin symbols:

$ a="$(perl -e 'print "x"x255')"; touch "$a" && { ls "$a"; rm "$a"; }
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

$ a="$(perl -e 'print "x"x256')"; touch "$a" && { ls "$a"; rm "$a"; }
touch: cannot touch 
`xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx': 
File name too long

but if i try with cyrillic, max long is just 127 symbols:

$ a="$(perl -e 'print "\xd0\xaf"x127')"; touch "$a" && { ls "$a"; rm "$a"; }
Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯

$ a="$(perl -e 'print "\xd0\xaf"x128')"; touch "$a" && { ls "$a"; rm "$a"; }
touch: cannot touch 
`Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯Ð¯': 
File name too long

but users can create whith cmd.exe or powershell.exe or explorer.exe 
files with 250+ long names with cyrillic symbols:

$ a="$(perl -e 'print "\xd0\xaf"x251')"; cmd /C "echo > $a" && ls -l
ls: cannot access

same problem with other tools - find, perl, rsync from cygwin repo.

Please, make the MAX_PATH not for 260 bytes, but 260 utf-8 symbols.

Thanks.
