Re: [ros-dev] [ros-diffs] [tfaber] 63953: [FASTFAT] - Do not use direct I/O since it limits read/write operations to 64 MB CORE-8410 #resolve

by cameron.gutman＠reactos.org

This seems strange. I understand that NT 5.x has a limitation of 64 MB MDLs on x86, but direct I/O was designed for exactly this case of large I/O operations. Has anyone verified that 2k3 doesn’t do MDL chaining for direct I/O when the transfer is larger than a single MDL can hold? Also aren’t there changes to the IRP dispatch routines required to cope with not having an Irp->MdlAddress pointer anymore?

Re: [ros-dev] [ros-diffs] [tfaber] 63928: [FASTFAT] - Properly handle errors in CcInitializeCacheMap, CcCopyRead and CcCopyWrite CORE-8410

Hey Thomas I think that you want to use _SEH2_YIELD in a few places here, that is, unless we want to completely ditch pseh2 in favor of pseh3 ;-) Regards Jérôme Le 24/08/2014 05:28, tfaber(a)svn.reactos.org a écrit : > Author: tfaber > Date: Sun Aug 24 03:28:01 2014 > New Revision: 63928 > > URL: http://svn.reactos.org/svn/reactos?rev=63928&view=rev > Log: > [FASTFAT] > - Properly handle errors in CcInitializeCacheMap, CcCopyRead and CcCopyWrite > CORE-8410 > > Modified: > trunk/reactos/drivers/filesystems/fastfat/CMakeLists.txt > trunk/reactos/drivers/filesystems/fastfat/fcb.c > trunk/reactos/drivers/filesystems/fastfat/fsctl.c > trunk/reactos/drivers/filesystems/fastfat/rw.c > trunk/reactos/drivers/filesystems/fastfat/vfat.h > > Modified: trunk/reactos/drivers/filesystems/fastfat/CMakeLists.txt > URL: http://svn.reactos.org/svn/reactos/trunk/reactos/drivers/filesystems/fastfa… > ============================================================================== > --- trunk/reactos/drivers/filesystems/fastfat/CMakeLists.txt [iso-8859-1] (original) > +++ trunk/reactos/drivers/filesystems/fastfat/CMakeLists.txt [iso-8859-1] Sun Aug 24 03:28:01 2014 > @@ -26,6 +26,7 @@ > add_library(fastfat SHARED ${SOURCE} vfatfs.rc) > > set_module_type(fastfat kernelmodedriver) > +target_link_libraries(fastfat ${PSEH_LIB}) > add_importlibs(fastfat ntoskrnl hal) > > add_pch(fastfat vfat.h SOURCE) > > Modified: trunk/reactos/drivers/filesystems/fastfat/fcb.c > URL: http://svn.reactos.org/svn/reactos/trunk/reactos/drivers/filesystems/fastfa… > ============================================================================== > --- trunk/reactos/drivers/filesystems/fastfat/fcb.c [iso-8859-1] (original) > +++ trunk/reactos/drivers/filesystems/fastfat/fcb.c [iso-8859-1] Sun Aug 24 03:28:01 2014 > @@ -340,12 +340,14 @@ > { > PFILE_OBJECT fileObject;

On the server outage

by Colin Finck

Dear all, As you've certainly noticed, one of our main servers providing the www.reactos.org website along with JIRA and FishEye was down yesterday. Problems began yesterday around 13:00 UTC and lasted till some minutes ago. This has happened due to a severe hardware failure on the hypervisor machine serving the affected VMs. Our hosting provider needed two attempts to find and replace the failed hardware. Finally, the crash has caused one database table to get corrupted. This one was repaired just now. No data has been lost though. All services should be up again now. If you still notice anything not working, please report to me. We're sorry for the caused inconveniences! Best regards, -- Colin Finck System & Network Administrator ReactOS Deutschland e.V.

Introducing ReactOS development accounts

by Colin Finck

TL;DR ===== Your SVN account == "ReactOS development account", because it will be used for more services than just SVN. You can now change the password on your own at https://lam.reactos.org Hi all, I've been trying to centralize our user accounts for some time now and finally have something to show. Your known SVN credentials have been imported into an LDAP-based user directory now. This gives us the ability to easily plug various services for developers into the directory: SVN, BuildBot, the participant list for meetings, especially the upcoming services like Mumble, development VMs and file sharing. You can view your account details and change your password on your own now. Just visit https://lam.reactos.org to do so. The E-Mail address shown there will be used e.g. for sending meeting invitations. As we all want the migration to go flawlessy, I've set up a temporary SVN repository at svn://svn.reactos.org/sasltest This should work just like our "reactos" repository: If you have write access there, you have write access in "sasltest" as well. It already works well for me and my SVN client, but I want confirmations from others too. Please do so by committing some junk into sasltest :) We have some members, who don't have SVN write access but participate in the monthly meetings. They will shortly receive an E-Mail with their account details. That doesn't give you SVN write access though, it's just for participating in the meetings for now :P I'll keep you informed when we finally plug our main repositories into the LDAP database. Note that this doesn't change anything with the ReactOS Website accounts and IServ mail accounts. Former ones will always be in a separate database as everybody can sign up there. Cheers, Colin
