Hi, yogev_ezra demands I have some simple test cases, so: I have attached a sample ext2 vdi image , for virtualbox. You can use this along with VirtualBox or QEMU, as an harddisk. For starters, you can copy any file to and fro any FAT* and ext2 partition, and it should work. File creation, and delet...

Hi, I see 3 bugs related to my code were found. I'll be delighted to fix those, but... yogev_ezra, on October 21st, PM'ed me: 1) You commit your code to SVN when you see fit. It can contain bugs. 2) I provide an acknowledgement certificate on the payment within 24 hours from your commit. 3) You publ...

Hi, By the way, a question: under which Linux user will KolibriOS access the disk (read/write/delete)? Is it "root" or what? (I just don't have a Linux machine right now to test it, so I thought it would be easier to ask you...) While doing the read/write/delete, yes. As for creation, it c...

Hi, Cheers to all! I was working on ext2{3,4} write support , for the KolibriOS Summer of Code . I'm pleased to announce that I've pushed all the code upstream. What I've achieved is refactoring all the ext2 code, splitting it up, adding "needs-own-module" code to kernel/trunk/fs/ext2.inc,...

Hi, I'm struggling with a particularly irritating bug, which means that write gets corrupted. I'll tarball the code and upload to ftp soon, and try to fix this soon so I can put up my final report. Regards, Shikhin EDIT: since this is some last minute rushing, I thought I'd provide some updates. I t...

Hi, I've been struggling with a heisenbug in the Write syscall, so can't commit some stable code yet. People found a bug (not sure whether it's part of your driver or not, but it is related to ext2/3/4 so I'll list it here): Linux SWAP partition is listed now, while it wasn't listed before. Our sugg...

Hi, D'oh. I think confusion on my part stemmed from the fact that you all referred to the colon as the semicolon . Anyway, I'll be sure to fix that. Another comment - we usually use file extension " .inc " for included files, and file extension " .asm " only for the main file. It...

Hi, Well, I've just had a look and everything looks neat and well organized, so kudos for that! Thanks! Some small remarks: In ext2.asm, I found this: add eax, 3054539008 ; (369 * 365 + 89) * 24 * 3600 First, why did you calculate this number? The following code perfectly works in FASM too: add eax,...

Hi,

I've committed all code till the last ftp update I made; intermediate code isn't stable.

Hi, Following my report from yesterday: I've put up 25.patch and 25.img. 25.img is the kolibri.img with the latest kernel build; note that CreateFolder now works too, so have fun with testing it. Rewrite should be easy to do now, but I think it requires Write too, so I'll do those together. I'd love...

Hi, Good to announce that linking is up and finished, in my 24.patch file. Now, I've got a query -- does ext2_Rewrite and ext2_CreateFolder need to "copy data from input buffer" too? sysfuncs.txt isn't too clear on this -- could somebody please address this ASAP? Regards, Shikhin P.S. @yog...

Hi, I just posted the latest report, with somewhat detail, 3 days ago. However, it's the end of the month, so I thought I'd just pop in here and say that not much has been added since the last report, but the next (probably three days later, at 1 week's time from the last report) report should conta...

Hi, Thank you very much for the report - that's the way it should have been from the beginning, and this is the way it should be done from now on till the end of your project (October 17th as I mentioned to you on IRC). Of course. I'm also pushing for English-only comments; English is a fairly stand...

Hi, I've uploaded my most recent diff; linking is coming near to a finish. I was about to rush it to an end today, but yogev_ezra informed me that my month long absence meant an additional month of work. That should be good, considering the fact that I just realized the importance of communication -...

Hi,

I'm on schedule, but the current code has a couple of bugs (which I'll hunt down soon). The next update with code will most probably be on the 17th.

Regards,
Shikhin
