| Juest | tupone: hey, would you think that master is not affected by those mathematical issues and whatever other sort of bugs that are in 2.4? | 13:58 |
|---|---|---|
| Juest | stuff that you've been fixing i mean | 13:58 |
| blast007 | Juest: I'll merge changes from 2.4 when I have a chance | 14:03 |
| blast007 | not super important right now though | 14:04 |
| Juest | blast007: oh okay, thanks for letting me know. yeah im not trying to stress it | 14:04 |
| Juest | doing some qa on those changes before releasing is more important than worrying about master, right? | 14:04 |
| tupone | Juest: most affect master | 15:40 |
| Juest | oh, thanks! | 15:40 |
| tupone | I guess all of them | 15:41 |
| Juest | do you have any fix that is too big of a change/breaking change? | 15:41 |
| Juest | as in, i wonder if you probably can find something that applies only to master or that you cant apply in 2.4 due to downsides | 15:42 |

| Juest | oh? | 15:44 |
| Juest | asan? | 15:44 |
| tupone | asan (Address Sanitizer) and ubsan (Undefined Behaiviour Sanitizer) | 15:52 |
| Juest | oh i see, thank you | 15:54 |
| Juest | are those like tools that inspect the sources? | 15:54 |
| Juest | sorry for dumbly asking | 15:55 |
| tupone | They are compiler switches that add code instrumentation, while not disturbing to much playing (playing like at half speed) | 15:56 |
| tupone | with valgrind you go 1 tenth or less | 15:57 |
| Juest | oh | 16:13 |

| tupone | I got several div by 0 when projecting. e.g. when roaming and drawing tanks labels. Maybe we are drawing our own label :( | 19:44 |

| Juest | what | 20:58 |
| tupone | another div by zero :) | 21:09 |
| tupone | Still some problem with project. Maybe the matrixes are not yet initialized ? | 21:09 |
| Juest | hmm, have you considered making unit tests? considering all those changes it sounds like it can be useful | 21:14 |
| Juest | i recall we had this conversation but still | 21:15 |
| blast007 | I feel like it would be an absolute pain to add unit tests to BZFlag, because we don't generally have nice self-contained units | 21:20 |
| blast007 | I had the start of some of them in 2.4.4, but removed them later. https://github.com/BZFlag-Dev/bzflag/tree/v2.4.4/tests | 21:22 |
| Juest | why? | 21:52 |
| Juest | hmm, 2.99 lived in master for a while until it was no longer feasible? | 21:57 |
| Juest | oh blast007 -echo and -echoAnsi do not really seem to do anything in windows, at least not in a user facing way | 21:58 |
| Juest | the stdout/stderr stuff on windows is usually found in the debugger output | 21:59 |
| blast007 | Juest: it writes out to a file on Windows | 22:57 |
| blast007 | I think at c:\Users\UsernameHere\AppData\Local\BZFlag\stdout.txt | 22:58 |
| blast007 | https://github.com/BZFlag-Dev/bzflag/blob/2.4/src/bzflag/bzflag.cxx#L860-L873 | 22:58 |
| Juest | oh thanks blast007, i didnt notice nor bother to look | 23:00 |
| blast007 | it's probably not documented, and it's a rarely used feature | 23:00 |
| Juest | yeah that's indeed the case | 23:00 |
| Juest | i've used it at times without knowledge lol | 23:00 |
| blast007 | It may make sense to just add a proper logging feature akin to logging found in IRC clients | 23:01 |
| Juest | yeah honestly just do that | 23:02 |
| Juest | complete with log rotation | 23:02 |
| Juest | will be out for 2.5? | 23:02 |
| Juest | there are probably efficient logging libraries that are optimized for size and speed | 23:02 |
| blast007 | I had found this one a while ago: https://github.com/gabime/spdlog | 23:03 |
| Juest | interesting | 23:04 |
| blast007 | (could work for bzfs as well) | 23:05 |
| Juest | https://www.reddit.com/r/cpp/comments/10v7yx0/quill_v270_released_asynchronous_low_latency_c/ | 23:05 |
| Juest | certainly | 23:05 |
| *** yuitimothy is now away: I've done some soul-searching and I still can't find it. | 23:06 | |
| Juest | moving from stdout/stderr to proper logging sounds like the right move | 23:06 |
| Juest | bzflag is still primitive in many technologies, really? | 23:06 |
| blast007 | quill sounds interesting too, so I'll add that to my bookmarks for BZFlag stuff | 23:09 |
| Juest | :P | 23:10 |
| Juest | i'd only use quill when the application is sensitive to latency | 23:10 |
| blast007 | I mean, do *would* be writing to a file in the main game loop, so it might be useful there | 23:11 |
| blast007 | s/do/we/ | 23:11 |
| Juest | interesting | 23:12 |
| Juest | i wonder if the lib is small enough to check in and not be a burden | 23:12 |
| blast007 | The game client is mostly single-threaded. Exceptions to that would be DNS resolution (via c-ares), audio, and screenshots (with some extra stuff related to that in the control panel for adding the message about the screenshot location). | 23:15 |
| Juest | ah hmm | 23:15 |
| Juest | well, logging gotta be async and multithreaded, right? | 23:16 |
| Juest | whats the control panel stuff exactly? | 23:16 |
| blast007 | control panel being the chat panel | 23:16 |
| Juest | ahh i see | 23:16 |
| blast007 | (it's a weird name, but that's how it's referred in the code and the UI, usually) | 23:17 |
| Juest | so the game console/chat/control panel can have stderr/stdout when various levels of debug and echo is passed? | 23:17 |
| Juest | there's a commit that disables that because its redundant or something? | 23:18 |
| blast007 | which commit are you referring to? | 23:19 |

| Juest | rocket league does this and source engine has -textmode | 23:26 |
| Juest | oh hmmm | 23:28 |
| Juest | 2.99 existed as a branch? | 23:28 |
| Juest | those times when it existed are a blur | 23:29 |
| Juest | but i do remember compiling it and pestering the chat about it | 23:30 |

| blast007 | 2.99 exists as a tag | 23:54 |
| blast007 | I think the stdout shows up if you run BZFlag from a command prompt | 23:55 |
| blast007 | been a while since I tried though.. maybe I was running a bash shell instead | 23:55 |
