Please FIX: Wrong prototype and implementation in Rtl
by Oliver Schneider 20 Mar '05

20 Mar '05

.\lib\rtl\largeint.c There's a sutraction performed in your implementation. But actually it's a logical negation (asm -> NEG; C -> ~) in this function of the low and high part: RtlLargeIntegerNegate() Oliver PS: I have no CVS access, so anyone here having it should fix this.

New SM + CSR exposes LPC bug
by ea 19 Mar '05

19 Mar '05

I created bug 585 for a blocking bug in LPC message queueing. It seams I can't fix it. :( There is something wrong in lpc/queue.c. New SM that loads subsystems reading the registry config and CSR that registers are attached to 585 (code *not* commited yet). If fixing the LPC bug is not possible easily, I'll change SM to use a scond thread to avoid cross calling from the same thread. ea

Re: [ros-dev] Crash at the end of Stage2 setup (2 systems)

Hi, --- ea <ea(a)iol.it> wrote: > maybe that is what I reported on the irc a few days ago (installing in > QEMU061/Win32). Thomas could not reproduce it. If I go through stage 2 setup quickly then it will crash. If I wait and go slowly over each page ReactOS will not crash. THanks Steven __________________________________ Do you Yahoo!?

[VOTE] Miscelanea branches
by Casper Hornstrup 19 Mar '05

19 Mar '05

I'd like to close this discussion with a vote. Should we allow branches (other than trunk) with mixed new development and bugfixes unrelated to the new development that is on the branch (miscelanea branches) ? [ ] Yes, do allow miscelanea branches [ ] No, don't allow miscelanea branches Casper

free handle table entries
by Hartmut Birr 19 Mar '05

19 Mar '05

Hi, currently the free handle entry list is a lifo list. This is not a good solution for process and thread ids because a id from a currently deleted process or thread is valid again after a very short time. I would like it to change the free list to a fifo list by using a double linked list. The u2 part of an entry has enough room for a list entry instead an index. - Hartmut

serial driver bug
by Saveliy Tretiakov 18 Mar '05

18 Mar '05

Hi. I tested a new serial driver in a vmware with 4 serial ports. It creates only one serial device and a symbolic link to it ("COM3"); When I write to "COM3" output goes to COM1 and mix with debug output there. This is a bug imho.

vfat bug (hartmut?)
by Gunnar Dalsnes 18 Mar '05

18 Mar '05

This problem prevents ros from deleting a file/directory (observed while running wine kernel32 reg. tests with param "path") around line 295 in vfat\finfo.c: (svn blame says Hartmut made the last changes around here) ------------------------------------------------ if (DispositionInfo->DeleteFile) { if (MmFlushImageSection (FileObject->SectionObjectPointer, MmFlushForDelete)) { if (FCB->OpenHandleCount > 1) { DPRINT1("%d %x\n", FCB->OpenHandleCount, CcGetFileObjectFromSectionPtrs(FileObject->SectionObjectPointer)); Status = STATUS_ACCESS_DENIED; } else { FCB->Flags |= FCB_DELETE_PENDING; FileObject->DeletePending = TRUE; } } else { ------------------------------------------------ Why deny deletion with STATUS_ACCESS_DENIED if FCB->OpenHandleCount > 1 ??????

RE: [ros-dev] A new sub-project
by Waldo Alvarez Cañizares 18 Mar '05

Hi: >It is true that a filesystem that has a usermode component >can not be used as a boot driver I beleive this is not true. There are operating systems (at least I could name one) with all the drivers running in user mode leaving only a minimal kernel. Is sort of a client-server model, and yes with protection for file/folders. Now the ROS boot loader first loads kernel-hal-fat driver-... It has to, otherwise how would you load the filesystem driver? Now switching ring 0 <-> ring 3 with that in RAM... If you also load ntdll that way. Hmmm Why not? I beleive that is enought to read/write something to disk. Regards Waldo

If he wrote on ros-general, I know the ext2 branch is here (and I tested your patches in october) To avoid this - in trunk : we should empty the drivers/fs/ext2 and|or #error it, refering to the ext2 branch. - Fill the ext2 web page in Wiki.
