A race condition is a behavior which occurs in software applications or electronic systems, such as logic systems, where the output is dependent on the timing or sequence of other uncontrollable events. Race conditions also occur in software which supports multithreading, use a distributed environment...
but it has a race condition in it, because Java servlets are multithreaded. The programmer has implicitly assumed that the variable count is the same when printed as it is after the previous line of code sets its value. This isn't necessarily the case. Let's say that Alice and Bob both...
The concept is called "mutual exclusion" (short Mutex), and is a way to ensure that only one thread is allowed inside that area, using that resource etc. How to use them is language specific, but is often (if not always) based on a operating system mutex. Some languages doesn't n...

These threads could run on a single processor. Or there could be multiple threads running on multiple processor cores. Multithreaded Programming in C on a Single Processor Multithreading on a single processor gives the illusion of running in parallel. In reality, the processor is switching by ...
This guidance amounts to strategies for being very methodical about protecting program invariants, which, as the table in Figure 2 shows, is more complicated in the multithreaded case. There are a number of reasons that this is more complicated when using multithreading and I will explain them ...

This is a proof that the race condition is possible in JavaScript even without multithreading. To avoid risky outcomes you need to make sure there is no possibility for processes to be executed at the same time. You can rewrite the previous function to make it safe as shown below. Another...
Multi-thread testing tests several active transactions at the same time. In this case, separate threads are created for the requests of the client. Whenever a request is made, a thread is created for the service or responds to the request. ...
This example graphically illustrates one of the most difficult types of problems to solve in multithreaded programming—the problem of race conditions. However, here the race condition is not a problem, because we've protected all of the critical code sections with a mutex. We're guaranteed that...
