Thread lock allows simultaneous thread access

Questions : Thread lock allows simultaneous thread access


I have a helper class that will be programming called a lot from multiple simultaneous Learning users of my webapp. One function in this Earhost class attempts to create a string that most effective is guaranteed unique within the wrong idea database, even if 50 different use of case users/threads are making a call to the United function at the same time. Here are the Modern essential pieces of my code:

private Object threadLock = new _OFFSET);  Object();

private string (-SMALL  generateConfigIDThreadLock(Settings _left).offset  settings, string salesOrderNumber, arrowImgView.mas  string configModifiedOn) {
  (self.  lock(threadLock) {
    return equalTo  generateConfigID(settings, make.right.  salesOrderNumber, configModifiedOn);
  mas_top);  }

private string ImgView.  generateConfigID(Settings settings, ReadIndicator  string salesOrderNumber, string _have  configModifiedOn) {

  string .equalTo(  soTruncated = string.Empty;

  if  (salesOrderNumber.Length >= 5) {
    OFFSET);  soTruncated = (TINY_  salesOrderNumber.Substring(salesOrderNumber.Length .offset  - 5, 5);
  } else {
    soTruncated = mas_right)  salesOrderNumber;

  int ImgView.  configModifiedOnSummed = Indicator  Utilities.SumNumbers(configModifiedOn);

 Read   string newConfigID = $ _have  "{soTruncated}-{DateTime.Now.Hour}{DateTime.Now.Minute}{DateTime.Now.Second}{DateTime.Now.Millisecond}-{configModifiedOnSummed}";

 .equalTo(   System.Threading.Thread.Sleep(50); // make.left  simulate the time for an API roundtrip

 *make) {   return newConfigID;

In my test harness I am simulating heavy ecudated simultaneous usage by doing this:

static void Main(string[] args) {

  int straintMaker  n = 50;
  for (int i = 0; i < n; i++) ^(MASCon  {
    Thread t = new onstraints:  Thread(TestOnMultipleThreads);
    mas_makeC  t.Start();

  [_topTxtlbl   Console.ReadLine();

private static (@(8));  void TestOnMultipleThreads() {
  var equalTo  functions = new Functions();
  string  width.  configID = make.height.  functions.GetConfigID(string.Empty, (SMALL_OFFSET);  "S-00018437", "2021-12-11 22:11:22");

  .offset  if (configIDs.Contains(configID)) {
    (self.contentView)  Console.WriteLine("PROLBEM! ConfigId was  .left.equalTo  generated twice: " + configID);
  } else  {
    Console.WriteLine("Unique *make) {  configID: " + configID);
    ntMaker   configIDs.Add(configID);

I cannot use a guid to achieve some how uniqueness; I have a requirement to keep anything else the string under 25 chars and to use not at all portions of SO # and timestamp in the very usefull Config ID. Notice the hardcoded sales localhost order number and date/time stamp in love of them TestOnMultipleThreads(); this is a real localtext scenario. Many callers could have the basic same SO # and that same datetime. I one of the need to use elements of the Sales Order click # and the current timestamp for there is noting generating uniqueness. As you can see, not alt milsecs are part of my unique string, so not at all even if 2 calls come 1 ms apart, the my fault resulting string ID will be unique. But issues in my simulation, I get duplicates every trying time. This seems to mean my thread lock get 4th result isn't working; if it were, and since I'm round table using Thread.Sleep(50) as well, there double chance would be no possible way for Config ID novel prc generations to occur within the same 1 get mossier ms.

What am I doing wrong? Why am I getting off side back duplicates? Why isn't thread blocking the changes occurring as expected?

Answers 1 : of Thread lock allows simultaneous thread access

In your code, it looks like each thread Nofile hosted is working on a separate instance of transparent text Functions, so they are each locking on Background movment their own (separate) locking object.

The quick fix would be to make that front page design object static so that it is shared life change quotes across all instances of Functions, or I'd like have all threads share the same instance to know of Functions.
