Hi,
I've just downloaded the latest setup-x86.exe to update my Cygwin
installation on a Windows XP box. While setup downloads the required
packages, it stops with a message saying:
Can't open
\\servername\path\to\Downloads\[url_of_mirror]\path\to\texlive-collection-documentation-base-20130529-1.tar.bz2.tmp for writing: No such file or directory
Problem is, if I try to create a file with the same name manually in
Windows Explorer, I apparently hit the maximum allowed path length just
after the 't' in 'tmp'. In other words, the package filename is exactly
two characters too long on my system and using my closest mirror. Setup
exits without updating the system.
Is there a way to fix this? I know that I can try and find a mirror with
a shorter URL, but I expect others to bump into the same problem sooner
or later.
regards,
Markus

You could create a symlink in \\servername\path pointing to
\\servername\path\to\Downloads\[url_of_mirror] to workaround this
I guess.
The only other way to fix this is to fix setup. A long time ago I
tweaked setup to get rid of the MAX_PATH path length restriction, but
apparently this only worked for the files to install, not for the
archive files. I'm just looking through the setup code for downloading
files, and it still calls the OS ANSI file API exclusively, rather then
the UNICODE API, which is the culprit for this problem.
Sigh. This is a lot of work still to do.

Just to close this issue gracefully: I received a patched setup from
Corinna off-list which no longer caused this problem. The problem may
thus be fixed in the next setup version.

Markus

I started down the path of removing the #(&# encoded mirror path names
in the download directory a while ago. I will try to get that rolled
out again. That won't solve the problem but it should help a bit.
In the meantime, I'd suggest at least renaming the [url_of_mirror] to
something like "A". I think that should still work with setup.
