QUESTION

Mysql per thread memory, variables that lead to thread memory usage?

Asked 2021-Jan-20 at 19:11

We recently upgraded from mysql 5.6 to mysql 8.0 on a few servers, one of the servers was fine, and has had no problems, but it has significantly less load than one of our other servers which has been running out of memory.

Our server launches, then grabs 300 connections, and keeps them open with a C3P0 pool to the mysql server.

We were running these servers on AWS on MySQL 5.6 with the same overridden parameters on 8GB of RAM, when we upgraded to MySQL 8.0.21 we started running out of RAM in about 1 day. We grew the server to 32Gb but didn't change the parameters. It's gone over 15 GB used and still going up.

We're pretty sure it's related to the per connection thread memory, but not sure why. From looking at MySQL tuner it looks like the variables that control per thread memory are:

You're calculating the per-thread memory usage wrong. Those variables (and tmp_table_size which you didn't include) are not all used at the same time. Don't add them up. And even if you were to add them up, at least two might be allocated multiple times for a single query, so you can't just sum them anyway.

Basically, the memory usage calculated by MySQLTuner is totally misleading, and you shouldn't believe it. I have written about this before: What does "MySQL's maximum memory usage is dangerously high" mean by mysqltuner?

If you want to understand actual memory usage, use the PERFORMANCE_SCHEMA, or the slightly easier to read views on it, in the SYS schema.

The documentation for PS or SYS is pretty dense, so instead I'd look for better examples in blogs like this one:

I have learned about File processing in C programming recently. And I was given homework which call me to read data on a .txt files and printf out the data

The problem I'm facing with is my output appear random alien word*(smth like this ╝ c 0.00 6?φ↨ê■` 0.00)* when i enter my selection.BUT I think I code it properly (fopen and fclose the files, read the files with fread) and I just don't get it why my programm come into an error. I spend almost 3 days on youtube and google everything but I still failed on it and it almost reach the due date.

can someone please help me? Rlly thank you. also if you're free, please show me a correct code of this program so that I could make it as a reference. If you're not free its okay then :D //Is my system flow correct , if i wanna read the files, and printf specific line from the files at certain condition. ( e.g. defining struct > open > if-else statement > do -while loop >end) ? or we have other flowchart which is more smooth

//is it possible that i read all lines of the files, but I only printf out one single specific line?if yes, how can we do this?

If you created the file using NotePad, or any text editor for that matter, you need make sure it saved the text as ASCII or UTF-8 no-BOM. Otherwise, you'll have to deal with code point conversions, as the codes for storing text vary widely. See Wikipedia Character encoding, the history is tightly entangled with how C processes strings of text.

Your text appears to be what we call a space delimited file. That means each line is a record and each field in the record is delimited by whitespace. Your struct however is an abstraction over physical memory that defines the fields and their types. You need to read the text file and convert each record into a struct.

Read up on the following:

You have options. You can read each line of the file into your struct using fscanf, or read each line into a string buffer using fgets and then use strtok to iterate over each token in the buffer and either strcpy, in the case of the string fields, and strtof for the float.

You'll find lots of examples of how others have solved similar problems in these search results: https://stackoverflow.com/search?q=%5Bc%5D+convert+string+to+struct%3F

Since this is a homework assignment, I won't just hand you code. Go study, pick a path and start writing code. As soon as you run into a problem, do a quick search here for any possible answers, and start a new question if you don't find the answer.

Multi-Value parameters are an option. You do not have to use a list with them although they are not very intuitive.

I've created a simple example with a list of country names and codes (e.g. [Country Code] = "IT" and [Country] = "Italy")

A created a multi-value parameter called CountryCode but I did not set the available values.

This Crash is device-dependent. This is not seen on other devices. only MOTO. There is no support from MOTO (on their ARCORE) as mentioned by their call center people. only generic support.

So after some time, I finally managed to find a source of the issue, so I'm posting it here since it may be useful for someone else with the same problem.

The answer is YES, it's possible to create ARReferenceImage objects programmatically, and use them on iOS 11.3.1 for image detection.

My problem was in the source images itself, and it looks like the improper scale of the CGImage was causing the crash. Downloaded from the API images are 180x240. By checking the sizes of the CGImage which used for the creation of the ARReferenceImage I realized that they're not scaled properly, so the CGImage size was the same as the source UIImage.

I decided to try to re-draw the images using the following:

How to check what git rebase had changed?

Asked 2020-Jun-10 at 12:44

Is there a way to check what git rebase had changed after doing the rebase and exiting rebase mode?

I used rebase to change the author name of previous commits.

While trying to do so, I rebased in wrong branch (i.e., master) which viewed to me in the rebase file some commits that were not my target. Therefore, I just quit the editor and it said "Rebase done successfully".

At the end, I switched to my local branch (i.e., vIO) and I could change the author name but I want to check that my other rebasing trials didn't affect the history. BTW, my local branch (vIO) is not yet pushed to remote.

I tried comparing local master to remote master by:

git diff origin/master...master

This didn't bring anything. Does this mean for sure that the master branch was not affected by the rebasing?

ANSWER

Answered 2020-Jun-10 at 12:44

git keeps a log for each separate branch, which you can access through the git reflog command :

git reflog master will show you the evolution of your local master branch,
git reflog vIO the evolution of your local vIO branch.

In this reflog, actions that were applied by a rebase will appear with a message :
