Current FS code works like this: lock (a mutex guarding access to) a partition, read/write data, unlock the partition. When a thread crashes while reading/writing, the partition is left locked. Therefore other programs can't acquire the lock and access that partition anymore. To illustrate this logi...

I have filed a bug #138 and reverted commit #8560 until the bug is fixed.

test eax,0 This always sets zero flag because AND X, 0 is always 0. Therefore the following JNE branch is never taken. Hence mcall -1 is always executed when a key event is received by a program. The reason why Alt+letter keys are not sent to the program is that 1. Programs expect ASCII codes by de...

Technically it is possible. But requires much time, and nobody is working on it.
I can share some knowledge if somebody wants to contribute.

* Starting the "KIW" image viewer allways resets the mouse speed settings to 5, 5 (sidequestion: What on earth the simple image viewer has to to with mouse settings? :O) Good point. I suspect this was done for a more convenient testing and should definitely be fixed. Give me time until to...

The main things I missed were FLAC playback and exFAT access :) Since FLAC is the second most used format (after MP3) in my music collection and most of my storage media/partitions are in exFAT. FLAC playback should be supported by fplay . Yes, fplay is a video player but it is based on ffmpeg and ...

Simics is a powerful whole-system simulator with such a killer features as checkpoints and reverse execution. It is now free of charge for open source developers. Now it should be easier to debug the kernel and drivers. Freely available packages include an example x86 machine running a Linux target...

dunkaist, я согласен, что ACL и дескрипторы - это круто и нужно. Но этого всего нет сейчас в Kolibri. Sometimes features depend on other features, it happens. It is for the topic starter to decide which design to implement. Было бы неплохо хотя бы набросать спецификации всего этого, прототипы функц...

Нечаянно не то значение записал в регист и диск испорчен! If file descriptors are used, you have to make two mistakes: first call open , then write syscalls. In big systems this is resolved by user and file permissions and program capabilities. Драйвер загружается по запросу, зачем эти API постоянн...

Считаю, лучше сделать отдельный драйвер - слишком острые API будут. Соответственно, нужно и как-то защитить возможные последствия от дурака. How driver is safer than a syscall? То есть вы считаете что нужно реализовать системые вызовы? Или я чего-то не понял... Yes but file descriptors first. With ...

I don't know how this should be done properly but the most obvious way to implement this functionality seems to be API of open, seek/tell, read/write, close.
Yes, this requires a kind of file descriptors but we need them anyway.

The disk is partinioned through DOS though. I formatted my test partition via 'mkfs.vfat -F16' in Linux and then copied files via Linux too. Not sure if this matters though. Maybe I should create a thread, as I managed to install Kolibrios on a HDD, without any other OS, and with very very very eas...
