Umask vs umask

danielb · April 13, 2008, 2:16pm

Hi,

Windows XP Home
Ruby 1.8.6 p114

I think I need another set of eyes on this one, because it looks to me
like Ruby isn’t picking up the changes I make with a custom umask, and
vice versa.

require ‘win32/api’
include Win32

S_IWRITE = 0000200
S_IREAD = 0000400

Umask = API.new(’_umask’, ‘I’, ‘I’, ‘msvcrt’)

Mimic file.c

def umask(*args)
omask = 0

if args.length == 0
   omask = Umask.call(0)
   Umask.call(omask)
elsif args.length == 1
   omask = Umask.call(args[0])
else
   raise ArgumentError, "wrong number of arguments"
end

return omask

end

p umask(S_IREAD) # 0
p umask # 256 (ok)
p umask # 256 (double check, ok)

p File.umask # 0 - wtf?

Why isn’t Ruby’s File.umask picking up the change? I see the same thing
if I set it with File.umask and try to read the changes with my own
umask.

Regards,

Dan

Could that be because Windows is not a *NIX?

In my Windows XP Home & Pro, with ruby 1.8.6 p111,
the File.umask works fine.

I noticed that it works as expected when I use the one click installer
but not when I use a Ruby built with VC++ 8.

Are you seeing the same thing?

Yes, I tested with VC++ 9.
It fails as same as your test.
I guess “msvcrt” is valid for VC++ 6.
The situation became more complex since VC++ 8.

Refer to http://msdn2.microsoft.com/en-us/library/abx4dbyh(VS.80).aspx

You should modify the line

Umask = API.new(’_umask’, ‘I’, ‘I’, ‘msvcrt’)

to

Umask = API.new(’_umask’, ‘I’, ‘I’, ‘msvcr80’)

It requires Microsoft Visual C++ 2005 SP1 Redistributable Package (x86)

When I try to link against msvcr80 I get:

umask_test.rb:4:in initialize': LoadLibrary() function failed for 'msvcr80': A dynamic link library (DLL) initialization routine failed. (Win32::API::Error) from umask_test.rb:4:innew’
from umask_test.rb:4

The first line of a build shows the options being used:

    cl -W3 -nologo -MD  -O2b2xty-  -DRUBY_EXPORT -I. -I. -I./

missing -D_CRT_SECURE_NO
_DEPRECATE -D_CRT_NONSTDC_NO_DEPRECATE -c -Tcarray.c

Do I need to use a different build switch?

The download link you mentioned suggests that I only need that patch
if I don’t already have Visual C++ installed. But, I do have it
installed.

I’m afraid that even after reading the first article I’m still not
sure what I’m supposed to do to make this work properly.

First copy “msvcr80.dll” and “Microsoft.VC80.CRT.manifest” to the folder
where ruby.exe runs.

And make “ruby.exe.manifest” in the the folder where ruby.exe runs with
the following content:

<?xml version='1.0' encoding='UTF-8' standalone='yes'?> <assembly

xmlns=‘urn:schemas-microsoft-com:asm.v1’ manifestVersion=‘1.0’>

Although there may be an easy way, this will work for you.

I gave this a shot, copying msvcr80.dll and
Microsoft.VC80.CRT.manifest from C:\Program Files\Microsoft Visual
Studio 8\VC\redist\x86\Microsoft.VC80.CRT into my CONFIG[‘bindir’]
directory, and created the ruby.exe.manifest as you suggested.

Unfortunately, that still didn’t work for me. I also just tried
copying the Microsoft.VC80.CRT.manifest to ruby.exe.manifest, but that
didn’t work either.

I’m not really sure where to go from here.

The version # ‘8.0.50608.0’ in the ruby.exe.manifest must be same to the
verision # in your Microsoft.VC80.CRT.manifest file.

The version # ‘8.0.50608.0’ in the ruby.exe.manifest must be same to the
verision # in your Microsoft.VC80.CRT.manifest file.

I checked that, as well as the public key token. Heres my
Microsoft.VC80.CRT.manifest, just in case:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

I’m not sure what the problem is. But, a more pressing issue is how
the build scripts should be altered so that either this happens
automatically, or so that it’s not necessary (if possible).

As I tested with msvcr90.dll on VC++ 9.0 compiled ruby,
I cannot confirm your problem.

Try google for msvcr80.dll problem .
