No execution of system calls in cygwin-perl after update

1 New Member
Hi there,

I recently had to update my old cygwin installation to a newer version.
I'm not quite sure what version I updated from or to - but the old
version came with perl 5.6, the one I updated to with version 5.8. This
is also the reason why I had to run the update.
So far so good.

In my perl scripts there are a lot of calls to application installed on
this particular windows system (such as MS compiler or MKS Source
Integrity). On the old cygwin-perl everything was just running fine.
Since I made the update none of those system calls seem to be executed.
I tried running the same command lines from within the cygwin shell -
and they work fine. From within perl they just seem to be ignored. I
don't get any error messaged (at least not from the perl debugger or
the shell). The call itself returns on $? just 256 which I didn't find
anything helpful about.

Do I have to set any permissions to the perl interpreter that existed
prior the update and have been over-written by it?

Can anybody help me?

Cheers,
Mac

How can I make it so that I can pass anything into os.system() any command that I would type into the command line (bash on cygwin)? For example, "lower" is a small script of mine that I use frequently, and I would like to be able to call if from python. os.system("lower") results in: lower: not found I want it to run "lower" just like it would if I typed "lower" at the bash prompt. How can I do that?

I've been playing around with Zope's RestrictedPython, and I think I'm on the way to making the modifications necessary to create a capabilities-based restricted execution system. The idea is to strip out any part of RestrictedPython that's not necessary for doing capabilities and do all security using just capabilities. The basic idea behind capabilities is that you don't give any piece of code you don't trust a reference to something...

If the C programs have UNIX system calls such as fork(), alarm(), etc.., we should call it UNIX programs, not traditional C programs?

I'm trying to figure out the webservices architecture for library that we currently use as a monolithic component. Every execution is expressed by a call like this one public static IList executeIt(someArguments)... To be completed teh executeIt method can take up to 15 seconds, so I need to use asynchronous calls.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
