ReactOS August and September Meeting Minutes

by Zachary Gorden

Though the August minutes were already posted on the forum, they are being resent here for people who may have missed them. August Summary A proposal was made to do winesyncs before a release to force the project to do a better job keeping things in sync and perhaps do a better job making syncs feasible/less time consuming. Rejected by plurality of votes. Questions about how/whether to continue the driver signing program was raised. An advisory vote was held and the majority wished to continue it in one form or another. Feedback based on the advisory vote was incorporated into revised guidelines posted on the Driver Signing wiki page. New projects are now required to find a sponsor ReactOS "core developer" willing to audit their code if they wish to get their driver signed. Decision to integrate arwinss into trunk under a separate directory structure and make it a compile-time option. Passed by majority vote. Decision to switch main Linux build server to use cmake. Passed by majority vote. September Summary Agenda 1. CMake Adoption Status 2. Release Preparation, Determination of Release Date 3. Webportal Upgrade Status 4. ReactOS Target Version Report 1. The build environments for both Windows and Unix have gone through several release candidates and are effectively finalized. For the Windows BE an installer release client using MSI instead of NSIS also needs to be prepared. Minor problems still seem to exist on Mac OS X when using a combination of GCC and LLVM, but these were deemed non-blockers. Building ReactOS using CMake has been reported to take more time than using rbuild, though developers are still working to verify and determine the cause. Current theory is related to changed debug format and more thorough dependency checking by CMake. At present the plan is to put the build environment release candidates on the Linux build servers and determine if there are any problems. The Windows build servers have already been running the new build environments for testing purposes. 2. Due to the significant number of regressions and overall bugginess of ReactOS' current state, release scheduling has been deferred until the next meeting. A list of regressions and bugs has already been compiled and the team intends to work its way through the reported issues in the meantime. At the next meeting, the OS' state will be re-assessed to see whether a release is viable or not. 3. Most of the modules needed to bridge Drupal with things like Bugzilla have already been completed. To speed the transition, a decision was made to retain the current website design. Once the transition is complete, the web team can go back to updating the site's theme. Desired content changes will also not block transition to the new backend. No timetable was given for when the transition would happen. 4. For a while the project adopted the goal of targeting the Windows 2003 kernel and the latest version of Windows for user mode components. Several developers however raised objections to this and presented examples where this methodology does not work. A specific example involved symbolic link support, which required Microsoft rearchitecture not only NTFS but also the kernel's security systems. Its addition in ReactOS, assuming it is done correctly, would require changes to the kernel to adopt features from the Vista kernel, thus violating the kernel target. With these considerations, the project has decided to set both the user and kernel targets to Windows 2003. Dependency on Wine for many user mode libraries actually complicates this, as Wine has been adding Vista and later APIs without proper segregation and the developers will need to figure out how to deal with this in the long run.

Tools and ways for our development

by Matthias Kupfer

Hi, at present I work for mid-sized company for ticketing, parking and mobile solutions in Germany (and Great Britain). I personally work in a project for railway services (using gsm-r network). To understand the tools given below I want to figure out our target and environment in short. We develop for embedded Linux systems with ARM-CPU and Qt-Framework. Therefore C++ was and is used as programming language. Apart from he usual tools like - make-alike build tools (written in perl - a project specific one) - regular make files for some special targets - SVN for source code management we use some interesting tools to keep the source readable and to preserve a minimum of source quality automatically (bear in mind we use C++ instead of C, for our purpose we need to alter some tools for our needs): - Hudson for automatic build and checking the source (see below) - cpplint.py (by Google) for some checking the source - cppcheck for another check of the source - doxygen for checking the missing documentation (in that special case check only by tricky configuration instead of costly generating all documentation files) - format the source code (after agreement of all devs) in a uniform style with astyle before commit (for ReactOS better as commit hook) - finally we gather all check results in one table and mark the results for hudson as stable (if no errors), failed (in case of any errors), unstable (in case of some low-prio warnings) Maybe we can think about some of them, because even if some problems of development remains, it might give us some edge and may also attract some devs. I don't make any suggestions, but I want to tell you how others work. Matthias PS: We are the first project in the company going that way and other project groups would like to adapt the way, because they see the benefit for their/other/future projects. -- Matthias Kupfer phone +49 371 236 46 52 Wilhelm-Firl-Straße 21 mobile +49 160 859 43 54 09122 Chemnitz, Germany

Re: [ros-dev] [ros-diffs] [dgorbachev] 53907: [NTOSKRNL] Use inline asm in KiIsNpxErrataPresent(). C code can be optimized in a wrong way.

by Alex Ionescu

Care to explain? If it can be optimized the wrong way -- use a pragma or fix the compiler. I hate these kinds of patches. I think Timo would agree.

NDK

by dmex

The NDK has allot of 64bit alignment issues mostly from omitted SIZE_T fields, There's at least 20 or so other structures with issues but here's two corrected structures below: typedef struct _SYSTEM_VERIFIER_INFORMATION { ULONG NextEntryOffset; ULONG Level; UNICODE_STRING DriverName; ULONG RaiseIrqls; ULONG AcquireSpinLocks; ULONG SynchronizeExecutions; ULONG AllocationsAttempted; ULONG AllocationsSucceeded; ULONG AllocationsSucceededSpecialPool; ULONG AllocationsWithNoTag; ULONG TrimRequests; ULONG Trims; ULONG AllocationsFailed; ULONG AllocationsFailedDeliberately; ULONG Loads; ULONG Unloads; ULONG UnTrackedPool; ULONG CurrentPagedPoolAllocations; ULONG CurrentNonPagedPoolAllocations; ULONG PeakPagedPoolAllocations; ULONG PeakNonPagedPoolAllocations; SIZE_T PagedPoolUsageInBytes; SIZE_T NonPagedPoolUsageInBytes; SIZE_T PeakPagedPoolUsageInBytes; SIZE_T PeakNonPagedPoolUsageInBytes; } SYSTEM_VERIFIER_INFORMATION, *PSYSTEM_VERIFIER_INFORMATION; // Class 22 typedef struct _SYSTEM_POOLTAG { union { UCHAR Tag[4]; ULONG TagUlong; }; ULONG PagedAllocs; ULONG PagedFrees; SIZE_T PagedUsed; ULONG NonPagedAllocs; ULONG NonPagedFrees; SIZE_T NonPagedUsed; } SYSTEM_POOLTAG, *PSYSTEM_POOLTAG;

Interesting article

by Aleksey Bragin

FYI: This is Linus' interview. http://h30565.www3.hp.com/t5/Feature- Articles/Linus-Torvalds-s-Lessons-on-Software-Development-Management/ ba-p/440 He very correctly outlines many things. One of the most important: "The other thing—and it's kind of related—that people seem to get wrong is to think that the code they write is what matters. No, even if you wrote 100% of the code, and even if you are the best programmer in the world and will never need any help with the project at all, the thing that really matters is the users of the code. The code itself is unimportant; the project is only as useful as people actually find it.” And this: "Way too many projects seem to think that the code is more important than the user, and they break things left and right, and they don't apologize for it, because they feel that they are ‘fixing’ the code and doing the right thing.” WBR, Aleksey Bragin.

ACPI enabled on Linux Testslave

by Colin Finck

Hi all, Just for your information, I have enabled ACPI for the KVM machine used by the Linux Testslave today. For reference, the full VM configuration is like this: * QEMU/KVM-based i686 ACPI machine * 256MB of RAM * 512MB HDD on IDE Primary Master * ReactOS ISO on IDE Secondary Master * AMD PCNet-compatible Network Adapter * COM1 port redirected to a virtual Linux terminal device * PS/2 mouse * Tablet pointing device on USB Usually useful if any KVM machine is controlled over VNC, but probably not relevant for ReactOS yet. As you see, there is no virtual sound card (disabled as of 2011-06-07 due to r52098 according to my notes). Is this still correct? - Colin
