Hello all,
I m facing an interesting problem related to semaphore in php.
We are using a huge business application running on LAMP. For database
operations we are maintaining centralized DB manager classes in php
which perform all the single table related activity. Before inserting
new record we are acquiring semaphore on specific key (all the tables
are having seprate sem keys), insert the record and release the
semaphore.

I can't seem to find a Semaphore class in the .Net framework. Does C#
provide any blocking container objects that will block a thread trying to
extract an element from an empty queue or does the .Net framework provide a
Semaphore object of some type? I've noticed a post to the urls
http://www.codeproject.com/csharp/BoundedBlockingQueue.asp and
http://www.codeproject.com/csharp/DijkstraCountingSemaphore.asp, which will
work if necessary,...

I tried using a Semaphore class (have included the full listing
reproduced from article Figure 1 at the end of this email) in .NET 1.1.
It works fine most of the time, however, I see the following error
occassionally:

Exception:
Too many posts were made to a semaphore in mscorlib.

Hello all,
I m facing a memory related problem with semaphores. Our business
application uses semaphores extensively and the limit imposed by the OS
on the number of semaphores that can exist on the system is only 128.
This could be increased to a higher value but that would not be a
permanant solution to my belief. We are using the sem_get, sem_acquire
php functions. After the use we are releasing the semaphore by using
sem_release.

To make it simple, I have a simple test C program which calls my
semphore library functions only. (It doesn't call any db2 function at
all). And the following is the test program:
#include "hasem.h"
#include <semaphore.h>
#include <stdio.h>

I'm having trouble creating a Semaphore with read-access rights for
everyone. Originally I was trying to use this code:
semaphore = new Semaphore(maxLocks, maxLocks, "RwLock#" + name);
but when using that code to create a Semaphore instance for an
existing system semaphore (i.e., the second time the code gets hit), I
get an UnauthorizedAccessException. So I tried specifying that
everyone has read rights:

Is there a posix semaphore wrapper for python?
Would that be a good addition?

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,...
