Summary: Process.create needs to explicitly make individual handles inheritable

Initial Comment:
I've encountered some versions of Ruby on Windows (in my particular case Ruby 1.9.1 compiled with MinGW) where IO.pipe does not create inheritable handles.  This causes problems when Process.create is used to create a pipe to a child process.  The attached patch to win32-process works around this issue by always explicitly calling SetHandleInformation to make the passed handles inheritable.

Message:
No, you're thinking of the :inherit option, which I do have
set to true; Process.create also sets it for you if you are
passing IO handles to child processes.

If the present software is helpful enough to add options it
knows you need?which is why we have high-level functions
like Process.create?it ought to make sure the objects are in
the right state for you (i.e. inheritable), too.

Thanks!

Hi,

Can't you just explicitly set the :process_inherit option to true and get the same effect?

Subject: [Win32utils-devel] Question on CreateProcess and handle inheritance
Message-ID: <6037b70c0909020355l28faaea4kaeed2eaa98f48c36@mail.gmail.com>

Hi,

I just wanted to make sure that I'm not confused by Michael Buselli's
comment and patch. As far as I can tell, if you set the bInheritHandle
in the SECURITY_ATTRIBUTES structure that's passed to CreateProcess to
true, it's the same as calling SetHandleInformation(handle,
HANDLE_FLAG_INHERIT, HANDLE_FLAG_INHERIT) after the fact.

CreateProcess:

lpProcessAttributes [in, optional]

    A pointer to a SECURITY_ATTRIBUTES structure that determines
whether the returned handle to the new process object can be inherited
by child processes. If lpProcessAttributes is NULL, the handle cannot
be inherited.

SetHandleInformation:

HANDLE_FLAG_INHERIT

   If this flag is set, a child process created with the
bInheritHandles parameter of CreateProcess set to TRUE will inherit
the object handle.

Or is this a case of "can" (i.e. it's possible for the child to
inherit the handle) vs "will" (i.e. the child process will definitely
inherit the handle)?

Regards,

Dan

You must notice that "the returned handle" has nothing to do with the
handle of stdin, stdout, or stderr. The SECURITY_ATTRIBUTES structure
provides security settings for objects created by various functions,
such as CreateFile, CreatePipe, CreateProcess, RegCreateKeyEx, or
RegSaveKeyEx. The returned handle can be a file handle, process handle
or registry handle.

I guess the child process will definitely inherit the handle when
bInheritHandles flag is set and the handle was not set by
SetHandleInformation(handle,HANDLE_FLAG_INHERIT, 0).

I think  Michael Buselli's patch is acceptable.

Hello Guys,

Me again in reply to Daniel's post:

http://djberg96.livejournal.com/169067.html

Since LiveJournal really sucks, I cannot simply register for
comment... no, it creates a whole LiveJournal account that I don't
plan on use.

Also, no OpenID.

Anyway, to comment: Did you tried rake-compiler?

http://github.com/luislavena/rake-compiler

Basically it allow Gem specification playing so you can do this:

rake compile

to build the extensions

rake native gem

to package both 'ruby' source gem and 'native' to your platform.

It also opens the possibility to cross compilation (I guess not useful
for win32utils project) but it is for MinGW powered Ruby.

Anyhow, wanted to chime in :-)

I know, could be shameless self promotion, but perhaps is helpful, dunno.

Cheers,

LJ says it supports OpenID:

Thanks, I really do need to take a look at rake-compiler. :)

Yes, but is not turned on or there is no way to select it... so cannot
comment :-P
(it just show empty parenthesis, no way to select it)

Hm, I wonder if I have to explicitly enable it. Let me poke around a bit.

Alright, I've changed the settings so that anyone can post (not just 
registered users), though comments from non-registered users will still 
have to be screened. I guess LJ still treats OpenID users as 
"anonymous". I didn't see a way to explicitly allow OpenID users, though.

Dan

Thank you Daniel,

LJ indeed treat OpenID as anonymous... Now I see the option for
OpenID, which will be screened

The CVS version of win32-clipboard supports the HTML formatted text.

Yes, you can checkout what's in CVS. I haven't released it yet because 
I've been mulling over the interface.
