Using Lock and Rlock in the same go routine

Asked 2021-Aug-25 at 03:34

I am working in an experiment using RWMutex in Go, and I realized that is possible to have this behavior with the follow code:

goroutine 1 - RLock
goroutine 1 - RUnlock
goroutine 2 - RLock
goroutine 2 - RUnlock
goroutine 2 - Lock
goroutine 2 - Unlock
goroutine 1 - Lock
goroutine 1 - Unlock

This is because your code has a race condition in it. You read-lock the map to read it, make a decision, and then write-lock it. There is no guarantee that when you get the write lock, the condition you made the decision on still holds.

The correct way would be to retest the condition after locking:

QUESTION

mov vs xchg in spin lock implementatoin

Asked 2020-Oct-07 at 20:47

I'm reading through this online book on x86 and I'm curious about an implementation detail in their example code for implementing a spin lock. In the example, they use a xchg to set a memory location to 0 rather than a mov and I'm trying to understand why that choice was made.

In the spin lock example there is a function, spinUnlock which puts a 0 in the memory location [sLock]. [sLock] is set to 0 if the lock is free and 1 when it is aquired. The spinUnlock function sets [sLock] to 0 freeing the lock. The code follows:

Only the author can say why the choice was made.

A single mov dword [sLock],0 would work fine; and an xchg eax, [sLock] (which has an implied lock) is likely to be more expensive (for both performance and code size).

All of the example's code is awful (e.g. no pause in the spinLock routine where it should be used despite having pause in places where it shouldn't be used at all); and their choice of example isn't good either.

Note: using spinlocks in user-space is "almost never" sane because the OS may do a task switch after you acquire a lock but before you release it, causing all other tasks to waste a massive amount of CPU time spinning with no hope of acquiring the lock.

"Loose" inter process communication

Asked 2020-Jun-28 at 10:35

I have two programs (namely dwm and slock). I want to trigger a function in dwm depending on events happening in slock and vice versa. The requirement is that both should be independent and run without the other program and also work together.

What is the easiest and/or the best (most efficient) IPC solution/method?

I've done it like Milag sugested in the comments:

a signal could trigger activity in the other proc; if you need a block of data as well, maybe use shared memory or R/W with a named pipe

Create an @Entity Notice which is your data type to be stored in your Room DB.
Create a View Model which is attached to your Activity/Fragment where you need to show this list.
Use your ViewModel to store the list from API into your Room DB.
Create a LiveData which observes on the DB and sends the updated list to the other view.

Code for Saving Data in DB. This needs to be run on Background Thread.
