 So ha, so my name is Matushe, and I'd like to make you aware of performance unit tests. Today I've pushed Commit to Master, which should help you to create some. So, why? We already have in their works running some tests, but it just loads and saves documents, which is probably the most important thing you want to test, but in some cases you may want to test also and other functions like, I don't know, mail match stuff or anything. So, how to make sure your feature stays fast? So, you have some feature, you want to make sure it's fast, so you improve it, and you create the unit tests, and then never any comment breaking it, or maybe even better, you first create the unit tests, and then you can improve it and watch how much is better, like this Commit saved 10%, so you can watch that. Some basics. In make file you want to call set performance test macro, and in source file you include callgrind header, and use some macros to tell it when the code is running you want to test, and then you will get the number of instructions. There is also example commit in Garrett for auto correction stuff, it's still in Garrett because it's not doing what I would like it to do, but you can have a look how to create unit tests, or what do you need. We already had enable volgrind variable, which is true if you have volgrind headers installed in your system, so you just make sure it's true, and you can, well, not made, there is a perf check target. So it's still not clear what to do with the unit tests, right now they, well, you set the number of instructions there, and if it runs longer it just fails, but this probably not what we want, it may be annoying, like sometimes it's just necessary that something takes longer, like recently loading empty writer documents is slower because there is sidebar by default, so there may be some reasons why it's slower, so we probably don't want to just fail, but I know maybe create some tables and watch the numbers. Okay, so basically that's all. It's simple to create such unit test, so we are ready to create one, and yeah, thanks. Seconds for questions, if anybody has. If it fails, it's some kind of a mount sword in the last time it referenced. Yes, yes. How much sword is it currently? Currently just one person, but yeah. I am not sure what to issue too with the results now, but yeah.
