Symbolic link to directory creation fails because of too long paths even if path <= 260 characters #216
Description
Hello!
I have noticed a strange issue with using ln -s inside of MSYS2 which I'm inclined to consider a bug. Even after I enabled long paths inside of the Windows registry ln -s will complain about paths being too long to symlink to and will exit with an error code of 1 when creating symlinks to directories. The strange thing is that this also happens when the paths are far less than 260 characters long. If the paths are short enough, the symlink will be created regardless of the error. If the path is longer than 260 characters, the symlink will not be created.
Steps to reproduce
Run the following commands inside of MSYS2 after enabling long paths in the Windows registry and rebooting:
mkdir -p /c/foo
cd /c/foo
ln -s .. bar
mkdir -p /c/betts/underscores/aiding/elegance/arginine/turkmen/ballet/bumsen/bendigo/steam/chronically/kannur/source/stalled/mangled/toolkit/strength/fateful/kurosawa/effectiveness/yardage/newport/repairers/prawn/angela/resembles/projekt/avalanche/storedge/alibi/gauteng/chaim/estudio/zante/thickened/retention/wieder/pretzel/maastricht/speciality/universalist/heine/nagios/spans/meetup/binders/strict/tooltip/beastiality/terrace
cd /c/betts/underscores/aiding/elegance/arginine/turkmen/ballet/bumsen/bendigo/steam/chronically/kannur/source/stalled/mangled/toolkit/strength/fateful/kurosawa/effectiveness/yardage/newport/repairers/prawn/angela/resembles/projekt/avalanche/storedge/alibi/gauteng/chaim/estudio/zante/thickened/retention/wieder/pretzel/maastricht/speciality/universalist/heine/nagios/spans/meetup/binders/strict/tooltip/beastiality/terrace
ln -s .. foo
MSYS2 Version
uname -a for my MSYS2 installation:
MSYS_NT-10.0-19045 ___________ 3.5.3.x86_64 2024-05-06 06:45 UTC x86_64 Msys
Implications
This bug can cause many kinds of frustrating problems because many shell scripts and tools like tar often need to create symlinks to other directories
I thank you in advance for investigating this bug!
