QUESTION

How is this code snippet an example of incorrect synchronization?

Asked 2021-Jun-15 at 12:46

I am trying to understand the example with incorrect sync code from The Go Memory Model.

Double-checked locking is an attempt to avoid the overhead of synchronization. For example, the twoprint program might be incorrectly written as:

According to the Go memory model:

https://golang.org/ref/mem

There are no guarantees that one goroutine will see the operations performed by another goroutine unless there is an explicit synchronization between the two using channels, mutex. etc.

In your example: the fact that a goroutines sees done=true does not imply it will see a set. This is only guaranteed if there is explicit synchronization between the goroutines.

The sync.Once probably offers such synchronization, so that's why you have not observed this behavior. There is still a memory race, and on a different platform with a different implementation of sync.Once, things may change.

Go WASM export functions

ANSWER

If you plan to write a lot of WASM in Go, you might want to consider compiling with TinyGo, which is a Go compiler for embedded and WASM.

TinyGo supports a //export or alias //go:export comment directive that does what you're looking for.

I'm copy-pasting the very first example from TinyGo WASM docs:

Why is it not 12 (4 + 8)? Does Rust have special treatment for tuples?

No. A regular struct can (and does) have the same "problem".

The answer is padding: on a 64-bit system, an f64 should be aligned to 8 bytes (that is, its starting address should be a multiple of 8). A structure normally has the alignment of its most constraining (largest-aligned) member, so the tuple has an alignment of 8.

This means your tuple must start at an address that's a multiple of 8, so the i32 starts at a multiple of 8, ends on a multiple of 4 (as it's 4 bytes), and the compiler adds 4 bytes of padding so the f64 is properly aligned:

TL;DR. You should check that the pointer returned by bpf_map_lookup_elem is not NULL.

With the following logs, the BPF verifier is telling you that, when it reaches the dereference of my_pid, the pointer may still have a NULL value. It thus contains a map value or a NULL value, i.e., map_value_or_null.

Why are these 2 instructions considered data dependent?

We needed the adress of t0

Registers don't have addresses: they have names; they have positions/index in the register file, and, they hold values.

Only memory has addresses.

Since, lw, does need the correct value of mem[$t0] + 4

That lw accesses mem[$t0+4], and it needs $t0's value so it can do the + .

The lw and sw instructions compute an effective address:

how does spring boot auto configure the driver of a special datasource?

Asked 2021-Jun-14 at 09:03

Without spring boot ,we must specify the detail of a data source,right?

ANSWER

Answered 2021-Jun-14 at 08:59

From DataSource Configuration in the docs:

Spring Boot can deduce the JDBC driver class for most databases from the URL. If you need to specify a specific class, you can use the spring.datasource.driver-class-name property.

So start without configuring anything and just putting the JDBC driver on the classpath. If it would not work, you can manually configure it.

Inno Setup Music Glitches when exiting

Asked 2021-Jun-14 at 07:52

I've used Martin Prikryl's code for my Inno Setup project. This is the link to his code:

How to make Stop and Pause/Resume/Play music buttons in Inno Setup

I used it with some tweaks on it but the problem is that the music glitches when I finish it.

For example, if the music is working while installing something and when I finally finish the setup, I still hear the glitched Audio for about 3 seconds! It's very annoying!

I think the problem is that we need to unload Music dll's before the installer finishes, as we do with the skin.

I hope you understood my situation and thanks in advance!

You've used -Xms to force the JVM to get ~30GB at JVM startup.

It has tried, and failed. It only obtained 8GB. It needs another 22-ish GB but cannot get it. That is what the error message is telling you. This is consistent with a dump that says the heap is only 8GB.

You're asking for more than the OS will provide. You'll need to figure out what's going on in the OS in general.

Your application code is probably not involved. The JVM is still initializing its heap in accordance with your command-line options.
