Aug 29, 2008 · A race condition occurs when two or more threads can access shared data and they try to change it at the same time. Because the thread scheduling algorithm can swap between threads at any time, you don't know the order in which the threads will attempt to access the shared data. Therefore, the result of the change in data is dependent on the ...
Jun 30, 2012 · According to Wikipedia, the term "race condition" has been in use since the days of the first electronic logic gates. In the context of Java, a race condition can pertain to any resource, such as a file, network connection, a thread from a thread pool, etc. The term "data race" is best reserved for its specific meaning defined by the JLS:
Sep 23, 2017 · Promise.race is a JS built in function that accepts an iterable of Promises (e.g. Array) as an argument. This function then asynchronously returns a Promise as soon as one in of the Promises passed in the iterable is either resolved or rejected. Example 1: var promise1 = new Promise((resolve, reject) => {.
Oct 15, 2013 · Race conditions occur when two threads interact in a negatve (buggy) way depending on the exact order that their different instructions are executed. If one thread sets a global variable, for example, then a second thread reads and modifies that global variable, and the first thread reads the variable, the first thread may experience a bug because the variable has changed unexpectedly.
27.9k2184109. 1. One difficulty in explaining the general concept is that race conditions manifest themselves in a wide variety of situations. If your goal is give your non-technical audience the sense that this is a generic problem type, you should try to offer more than one example. answered Nov 22, 2008 at 0:07.
The chief differences are: race 's promise is rejected when the first promise you give it is rejected; any 's promise isn't, because another promise may be fulfilled instead. any 's promise's rejection reason will be an AggregateError, but race 's rejection reason will be the rejection reason from the first promise that was rejected.
13. I've heard about many application developers having a bit of trouble in regards to race conditions in database processing. A typical example goes something like this: User 1 selects a field, say, numStock, which is 3. User 2 also selects numStock, which is still 3. User 1 decrements numStock (in the app), and sets it to 2 in the database.
Aug 2, 2022 · Yes, race conditions can and do occur in JS as well. Just because it is single-threaded it doesn't mean race conditions can't happen (although they are rarer). JavaScript indeed is single-threaded but it is also asynchronous: a logical sequence of instructions is often divided into smaller chunks executed at different times.
Nov 18, 2014 · int *tmpsum = input + i; #pragma omp critical. sum += *tmpsum; } This eliminates the race condition as only one thread accesses and writes to sum at a time. However, the critical directive is very very bad for performance, and will likely kill a large portion (if not all) of the gains you get from using OpenMP in the first place.
this.sText = null; // Suspected race condition is here. return sRetVal; } } sText is populated asynchronously by other functions in the class. I belive a race condition is happening between string sRetVal = this.sText; and the following line this.sText = null;. Can someone suggest a way to avoid or prevent this race condition?
