Only moderators and administrators of Roblox can lock threads on Roblox.
Yes. Whenever a thread needs to read or write to memory shared with concurrent threads, it must prevent other threads from writing to that memory at the same time. That is, the threads need to be synchronised. Typically, a thread will acquire a lock on that memory, releasing it when it has finished with the memory. Only one thread can acquire a lock at any given time, so if the lock is already acquired by another thread, the current thread must wait for it to be released. However, there are often times where two or more locks need to be acquired. So long as every thread acquires locks in the exact same order this is not a problem. But if a thread acquires the locks in a different order, we can easily end up with a deadlock. Consider the following pseudocode: function f () { acquire lock A acquire lock B // ... release lock B release lock A } function g () { acquire lock B acquire lock A // ... release lock A release lock B } If f is invoked in one thread and g in another, we can easily end up with f acquiring lock A while g acquires lock B. Function f is then left in limbo waiting for function g to release lock B while g is waiting for f to release lock A. They are deadlocked because neither can progress any further.

Recursive locks (also called recursive thread mutex) are those that allow a thread to recursively acquire the same lock that it is holding. Note that this behavior is different from a normal lock. In the normal case if a thread that is already holding a normal lock attempts to acquire the same lock again, then it will deadlock. Recursive locks behave exactly like normal locks when another thread tries to acquire a lock that is already being held. Note that the recursive lock is said to be released if and only if the number of times it has been acquired match the number of times it has been released by the owner thread. Many operating systems do not provide these recursive locks natively. Hence, it is necessary to emulate the behavior using primitive features like mutexes (locks) and condition variables.

Yes. When two threads attempt to lock the same two resources but in a different order, it's possible for both threads to lock just one of those resources and thus block the other thread from locking the other resource. Both threads are waiting for each other thread to release the other resource. To prevent this, whenever a thread locks multiple resources, always lock them in the same order.

Race ConditionsA race condition occurs when two threads access a shared variable at the same time. The first thread reads the variable, and the second thread reads the same value from the variable. Then the first thread and second thread perform their operations on the value, and they race to see which thread can write the value last to the shared variable. The value of the thread that writes its value last is preserved, because the thread is writing over the value that the previous thread wrote.DeadlocksA deadlock occurs when two threads each lock a different variable at the same time and then try to lock the variable that the other thread already locked. As a result, each thread stops executing and waits for the other thread to release the variable. Because each thread is holding the variable that the other thread wants, nothing occurs, and the threads remain deadlocked.
Thread safety is a term that is applied to a language's ability to safely modify the same memory location concurrently in multiple processes. A language that does not have thread safety cannot guarantee program correctness. Synchronization is one of the most common means of offering thread safety. To understand thread safety, you must first understand multitasking. A program running multiple tasks (called threads) at once does not actually run all of the threads at the exact same time. Instead, each task takes up a small sliver of the CPU's total processing time, and when it reaches a stopping point, or when an amount of time has elapsed, it is suspended, set aside, and the next task gets a chance to run. This happens so quickly that users have the appearance of many things running at once. However, when two threads are trying to use the same memory resource, bad things can happen if they are interrupted at the wrong time. Consider these two threads: Thread 1: Load x. Add 5 to x. Store this result in x. Thread 2: Load x. Add 10 to x. Store this result in x. Now, if thread 1 runs before or after thread 2, there is no problem. However, if thread 1 is interrupted, you might see a bug: X = 0 Thread 1: Load X (0) into reg1 (0). Thread 1: Add 5 to reg1 (5). Thread 2: Load x (0) into reg2 (0). Thread 2: Add 10 to reg2 (10). Thread 2: Store reg2 (10) into x (0 -> 10). Thread 1: Store reg1 (5) into x (10 -> 5). In case you missed it, you'll see that if 10 and 5 are added to x, the total should be 15. However, thread 2 preempted thread 1 at a critical point, and so thread 2 was unaware that x should have been 5, not 0. Since thread 1 had no idea that thread 2 was going to preempt the processing at that time, it didn't know that X changed to 10, and thus clobbered thread 2's work when it resumed. In order to fix this, you add a synchronization lock. This prevents a thread from starting after a critical point until the critical point has passed. It would look like this: Thread 1: Lock x. Load x. Add 5 to x. Store x. Unlock x. Thread 2: Lock x. Load x. Add 10 to x. Store x. Unlock x. Now, the logic might look like this: Thread 1: Lock x. Thread 1: Load x. Thread 1: Add 5 to x. Thread 2: Lock x. (Cannot lock, so wait). Thread 1: Store x. Thread 2: Lock x. Thread 2: Load x. Thread 2: Add 10 to x. Thread 2: Store x. In this example, thread 2 was forced to wait on the other thread. While overall processing speed is reduced, the system successfully added the numbers in order without losing any results; x would be 15 after those two threads were done.
Object Locking is the concept by which a thread that is running obtains a lock on an object that it wants to access. This is done to ensure that no other thread can modify the object that the current thread wants. Multiple threads modifying the same object can result in deadlocks, race conditions and inconsistent data
aittle lock tite on the thread may work. other than that the thread in head is worn ,.this can be corrected by removing head ,retapping the thread and replacing head. maybe even easier just to replace the head with a new one
You thread a needle with the thread you want to pull through, pass the needle into the material slightly within the margins of the pattern and pull the thread through. You don't really have to pull the top thread through to tie off because the stitch density is high enough to lock the thread, you can clip close. If you feel the need, unpick a few stitches (don't rip them, unravel the top and bobbin threads) until you have enough length to work with, pull the top thread through the fabric with the bobbin thread ad tie them together. When you change top thread, lay a short tail of the previous color and the new thread across the next pattern section and the thread will be locked. Same idea when you change the bobbin thread
