    Post bug reports or feature requests what you feel need some publicity. I'll post mine: Default "styled elements" appears to the inherited form needlessly (into dfm) https://embt.atlassian.net/servicedesk/customer/portal/1/RSS-779 Add Compiler/AST assisted "With remover" refactoring tool https://embt.atlassian.net/servicedesk/customer/portal/1/RSS-1666 SimpleRoundTo returns wrong value https://embt.atlassian.net/servicedesk/customer/portal/1/RSS-1651 -Tee-

    Sometimes one have questions that answer is not that easy 🙂 Or need quite bit of work. Lately I've had two. Where this unit is linking from? Which units in this project has initialization and/or finalization sections? I bet there are tons of these good questions we sometimes would need answers for 🙂 There might be something for these. Plain search for files does not help usually, because all depends what is linked into the specific project. -Tee-

    Hello, Tried to find the documentation of [ref] attribute, famously used in FreeAndNil -implementation lately, but could not find it from Embacdero help. (FreeAndNil is defined as: procedure FreeAndNil(const [ref] Obj: TObject);) So could someone point me to the documentation of the attribute ands/or explain what it actually does? -Tee-

    JSON benchmarks

    Tommi Prami replied to pyscripter's topic in RTL and Delphi Object Pascal

    Way cool! Is there test/comparison is Objects and/or Record serialization supported and speed etc?? Did not check code, because bit busy... I've used Grijjy in one of my hobby projects for serializing objects and/or records. Can't remember which they all are, poossibly both)

    Help with JWToken

    Tommi Prami posted a topic in Network, Cloud and Web

    { "aud": "1", "jti": "c455147e32d593e35fe", "iat": 1746708640.21844, "nbf": 1746708640.218443, "exp": 1746715840.20109, "sub": "8314", "scopes": [ ], "user": { "name": "Prami Tommi", ... I've got JWToken that to me seems that is not standard. exp etc should not be float, but "UnixDate" is integer (Can't remeber what it is called on top of my head.) Is this some weird standard or just plain wrong? Did some googling but did not find any JWToken standard that would accept this. -Tee-

    Unix Epoch is seconds, maybe fractions of seconds. But never the less, to me it seems to be agaisnt the standard. That it should be integer.

    Do you have any good sources of this? (To send people that might be interested)

    People tend to forget things. Right? As I recall ChatGPT gave virtually identical code also, but does not change the fact that I messed up... (EDIT: What I tried to say with that ChatGPT thing wea that I think (if recall) made ChatGPT implementation first. Checked out the API calls made, Google search and found the Grahics32 implementation and went with that. I think I had no intention to make the reposiotory public of that extracted version. As I was just testing the effect of the performance cores only thing out of curiocity, but at some point thought that mayeb some one also would like to use that. At that point most likely did not even think of the origin of the code any more. etc. I should have, for sure. Would not like to hijack more this thread on this, hope all is good now as the license is changed and added reference to the oigin, make issue on the project if something else is needed to fix)

    Is there Lock free or Thread safe containers in Sping4D... Asking for a friend 😉 -Tee-

    At least in my case, I ran 7-Zip processes in parallel, windows did piss poor job of allocating those prcesses to perdormance cores. Anyones mileage migh vary for sure.
  12. Tommi Prami
    It is mostly from there. I think. I thought I made it clear in code or GitHUB, let me check. I think I found few starting points, when searching the solution for the problem. If you’re referring to what I said earlier, that I did write it. I honestly did no longer remembered where it originally came from. I’ll make sure to give credit to the project. In other words, I had no intention of taking credit for something that isn’t mine. -Tee-

    Helllo, Depending on your CPU, you might need to set Affinity mask for the threads. If you have new Intel CPU with P and E cores you get wildly different results depending on which core threads are running at. Made siple unit top get Affinities: https://github.com/TommiPrami/Delphi.ProcessAffinity.Utils If you use it and find bugs, please make pull reguest. -Tee-

    Rapid.Generics revamp

    Tommi Prami replied to Alex7691's topic in Delphi Third-Party

    Could you please make the benchmark results like in the original version has. And possibly add the original into the mix, so can see how much the bugfixes ads overhear, correctness sometimes sadly has some penalty 😉 But anyhow, would be good addition.

    OtlParallel Memory Leak

    He was most likely talking to me, not to you, but he started it ans for sure not been insulting everyone, so... Not sorry...

    OtlParallel Memory Leak

    Tommi Prami replied to Celebr0's topic in OmniThreadLibrary

    Heh.. You seem to have no crasp of Multi threaded development, and fail to listen ones that REALLY know what tey are talking about,. (No need to listen me, but above there are messagews from people, that really know their shit, but...) -Tee-

    OtlParallel Memory Leak

    Tommi Prami replied to Celebr0's topic in OmniThreadLibrary

    If you write and/or access same string from multiple threads, is not thread safe. If you did not get errors or memory leaks is pure luck, or you did not check memory leaks with tool, that actually will report you the actual horror of updating strigg from multiple thread without proper protection (not a condom) -Tee-

    function declarations without ; at the end

    Tommi Prami replied to Günther Schoch's topic in RTL and Delphi Object Pascal

    Maybe you could make bug report to emba, maybe they fixit or not. -Tee-

    Works. Thank you very much! -Tee-

    What does [ref] attribute actually dows

    Tommi Prami replied to Tommi Prami's topic in RTL and Delphi Object Pascal

    Tried that with record as parameter, did not see any speedup, const and const [ref] had same performance. Winning clearly if it was passed as by value eith const ore var. I was jsut thinkin that could there be places and code (in my code ba se for example) thjat could benefit from [ref]? -Tee-

    What does [ref] attribute actually dows

    Tommi Prami replied to Tommi Prami's topic in RTL and Delphi Object Pascal

    I have been in impression that const actually would do something like that already. So parameter would be passed as reference. Will juust not allow changin it.... Is there some clear benefit of using [ref],m unless in need of doing something like in the FreeAndNil iomplementation.
  23. Tommi Prami
    I see the same behavior, with single 4K monitor.

    Yellow, Has anyone done parallel tests, of some kind. Some tests I have to run takles quite a long time, and might be nice to run those in parallel., In this case tests are just procedure with all code, that does something for different inputs (from predefined array etc). So in theory it would be simple, with TTask from PPL. I was just thinking what I have to take into consideration if test fails etc. I would need to use PPL, for these, sadly OTL is not possibility. As far as I know, there is nothing built in in the DUnitX. -Tee-

    Running tests in Parallel (or sub test in side one test)

    Tommi Prami replied to Tommi Prami's topic in DUnitX

    Yellow, again... Did Quick tests with PPL, seems that tested code it self did not work wery well when runniing in parallel. Do'h Heve to to think of this later... Code should be about thread safe, but did not cope, or at least I did not saw anything that was obviously not thhread safee and protected few spots with Critical section. -Tee-
