VOTE RESULTS: Switch to Wine Debug System

by Alex Ionescu

The results have been delayed for a day due to some last minute questions by Emanuelle. The final results are now in: YES, switch to a "Wine-Inspired/Compatible" Debug System, but using NT Debugging facilities as channels: 7 UNDECIDED/HAS RESERVATIONS: 2 There were no "NO" answers, but both Eric and Hartmut expressed certain disagreements. I've replied to them but have yet to receive a reply to my arguments. In any case, by a majority, the new system has been elected. We now need developers to implement it :) Best regards, Alex Ionescu

Compatibility Problems

by James Tabor

Hi, Our compatibility with w2k and XP sux! Here is a old psx.exe command and compare it with the new windows 2k compatible one we have. http://adsl-64-217-116-74.dsl.hstntx.swbell.net/ftp/pub/ReactOS/psx.exe Just in case! Looking at Nebbetts book Win NT/2k Native API Ref, our SYSTEM_PROCESS_INFORMATION for w2k is not close at all! Where is LLLONG or LONGLONG PrivatePageCount? What is funny, psx.exe uses NT4 structures! So how can we use w2k structs with w2k and see if they really work? Thanks, James

Re: [ros-svn] [hpoussin] 15474: Add ReactOS version at the start of the debug log

The version info is already displayed on screen anyways..I don't get the point of this commit. Best regards, Alex Ionescu

VOTE: Switch to Wine Debug System

by Alex Ionescu

VOTING TOPIC: Switch to Wine Debug System, a run-time configurable Debug System in which various debug modes can be used (TRACE, WARN, FIXME, ERROR, etc). It would use DbgPrintEx along with Debug Filters (just like on XP) which can be configured at run-time in the registry to set how many of the messages to show. I believe the current WINE system has the library doing all this checking, but it's possible they do actually use the NT method. DbgPrintEx and filter states are currently unimplemented in our ntdll/ntoskrnl, so they must be implemented. Additionally, these Debug Messages would only be inserted into the code for a DBG build, just like it is currently done now. Finally, using this system will allow us to better share code with WINE. PROS: - Configurable debugging - More versatility then just "Print Always" and "Print if I remove NDEBUG" - Better code sharing with WINE - Will lead to the implementation of some DbgPrint functions which NT Drivers are bound to use. CONS: - Requires developer time to switch to this system. - Requires implementing some Kernel Functions. VOTING TIME: 2 weeks. Results announced Monday 23rd at 5PM EST. VOTING CHOICES: - Yes! Get rid of DPRINT/DPRINT1 and implement a run-time configurable Debug System with multiple verbose levels, based on WINE syntax and Windows NT implementation. - No! Stick with the current static, compile-time DPRINT/DPRINT1 system. VOTING OPEN TO: Due to the nature of this source-level change, voting is opened only to developers. Best regards, Alex Ionescu

Re: [ros-svn] [jimtabor] 15466: This is a CompareStringW hack to get (7z313.exe /Q) to install. If anyone else has a better way, go for it!

I'm guessing with the compare string hack, it can be wrong, but? Anyone else with something better, I'm open! Thanks, James
