Recent Bootvid Commit

by Ros Arm

Hello! While the state of the original code is horrendous, and removing it was a step in the good direction, this simplified implementation omits many of the optimizations and specific VGA tricks that the original "author" of the code had intended to duplicate. If you'd like, I would be open to talking to eVb (we both have some experience with VGA programming) to create an efficient 4BitBlt routine similar to the original one that has been removed, but one that actually has basis in actual fact and isn't of the nature this original implementation was. I can see the original code was converting packed data into per-plane (planar) data and had special edge handling, but it looks like the original author did not realize this, and most of the modulo-and-shifts appear as bitwise ANDs (compiler optimizations), which is just plain confusing. Since the rest of bootvid is probably the same "quality", we could take a good look at it, both from a coding and legal standpoint, if you'd like. -r Author: gschneider Date: Sun May 30 01:54:47 2010 New Revision: 47431 URL: http://svn.reactos.org/svn/reactos?rev=47431&view=rev Log: [BOOTVID] Dramatically simplify 4bpp blitting routine See issue #5103 for more details.

Translations of usrmgr cpl

by Eric Kohl

Hi! It is really funny to see that translators don't seem to understand the simple meaning of: /* * Attention Translators: * DO NOT TRANSLATE THESE RESOURCES YET! */ It means: DO NOT TRANSLATE THESE RESOURCES YET!!!!!!! Got it??? Yes, but why? Because usrmgr is not finished yet from a programmers point of view. Most of the underlying infrastructure ist entirely missing. Right now, usrmgr is completely useless and its look and feel might change without prior notice. So please don't waste your precious time by adding more translations! Please translate other missing texts instead, but leave usrmgr alone. At least as long as the little note at the top is still in place. Thank you very much for your attention! Regards, Eric

Kernel Question

by ahmet alper parker

Hi all, I am new to this mail group and have a question that probably needs your kind of technical knowledge to answer. I want to use reactos, however, up to its completion, can I use some libraries on windows to replace them? In example, wine libraries can be superseded by original windows libraries if you own them. I want to make the inverse of this simply for security reasons to use a kernel fully opensource and which have a documented api. So can I use ntkrnlos.exe and hal.dll or similar in original windows installations to replace propriety kernel and libraries for security reasons? If yes, which of them should I use, and are they complete to replace them? Also a second question may arise as "the priority of reactos development can be focused on firstly these parts of the project or not?"... Best Regards... Ahmet Alper Parker

Concerning regedit r47251: inform the user that search is complete

by Gregor Schneider

Hi Michael, there is no need to hardcode the messagebox output language to english. In the resource files a string exists for what you're doing: IDS_FINISHEDFIND (probably already loaded into a string in the code somewhere). Thanks, Gregor

Re: [ros-dev] [ros-diffs] [mjmartin] 47226: [win32k] - Change the first parameter type from HWND to PWINDOW_OBJECT for IntKillTimer as it makes more sense. Activate IntSetTimer, already done by James. - Add flag TMRF_DELETEPENDING. Destroy timers when this flag is

by Ged Murphy

Congrats, good stuff Michael :) -----Original Message----- From: ros-diffs-bounces(a)reactos.org [mailto:ros-diffs-bounces@reactos.org] On Behalf Of mjmartin(a)svn.reactos.org Sent: 15 May 2010 20:41 To: ros-diffs(a)reactos.org Subject: [ros-diffs] [mjmartin] 47226: [win32k] - Change the first parameter type from HWND to PWINDOW_OBJECT for IntKillTimer as it makes more sense. Activate IntSetTimer, already done by James. - Add flag TMRF_DELETEPENDING. Destroy timers when this flag is set Author: mjmartin Date: Sat May 15 21:40:33 2010 New Revision: 47226 URL: http://svn.reactos.org/svn/reactos?rev=47226&view=rev Log: [win32k] - Change the first parameter type from HWND to PWINDOW_OBJECT for IntKillTimer as it makes more sense. Activate IntSetTimer, already done by James. - Add flag TMRF_DELETEPENDING. Destroy timers when this flag is set in ProcessTimers to allow any timers that have expired to have the WM_SYSTIMER/WM_TIMER messages posted to message queue before being destroyed. - Fix error in FindTimer, it was always returning a Timer and it needed to return NULL if the specified timer did not exist. - Fix error in PostTimerMessages, need to handle cases where the Window object is NULL which occurs when requesting messages for any window belonging to the thread. - In co_IntPeekMessage, simply call PostTimerMessages to have WM_SYSTIMER/WM_TIMER messages posted for expired timers. Remove call to old timer message handling. - TODO: Code using the old timer implementation needs removed. - Fixes bugs #2393, #3634, #2835. Commit dedicated to JT and Mr. Roboto.

Open Source Terminal Server

by Jan Blomqvist Kinander

Hi Developers, I have been aproached by a certain Gonzalo from Colombia, he claims to be a developer who wants to make a Terminal Server Clone, I enclose the mail he sent me, please have a look at it and answer him. Yours Sincerely, Jaix Bly >>> Hey Jaix, i'm Gonzalo from Colombia (South America) tecnologia(a)slmsistemas.net I'm a coder, i develop more than 500 utils and apps for terminal server and citrix .... i have a product called Galeon that is a "clon" of terminal server with shell replacement, full duplex sound, universal printer driver, etc ... I want to develop a Open Source Terminal Server based in something like VNC and OpenVPN Opening many sessions in windows is really bad idea ... for kernel stuff and another csrss, smss problems ... terminal server blue screen, black screen, printers, etc ... so i have an idea for a workaround ... Is open a session using createwinstation api ... in that session, create multiples desktops, using createdesktop api, in each desktop will be secure shell replacement, ejecuted using x user credentials (runas) ... the printing is gonna be universal virtual printers that receive the buffer from the win32, and send the emf or pdf to the client ... Using Virtual Channels is a pain in the ass ... because they all travel using only one tcp socket ... (really bad idea) so, problems with video, audio, performance, etc ...i think we can use openvpn to connect to only one port (443 to ssl vpn) and after the vpn is connected, we can open many socket (each service) between the client and the server desktop ... so we can send printing, sound, video, etc ... I have many things already developed ... createwinstation, createdesktop, impersonate users, universal printer, openvpn implementation .. etc ... but i need help in other areas, like the video grabber in the desktop (maybe a modified vnc) i can make a printscreen of each desktop, and send the jpg ... and is working, but is a really bad idea ... This product can merge with ReactOS .. and be the ReactOS terminal server ... https://sourceforge.net/projects/oswts/ What do you think? Do you receive this mail?

Partial build (newbie question)

by Mad Alchemist

Hello! I already have almost latest trunk build of ReactOS installed. Now I want to try modifying some sources, but recompiling whole system takes about 8 hours on my very slow PC. How can I recompile only modified part of the system? I am using RosBE for Linux version 1.5.

Regression fixing

by Aleksey Bragin

Hello, as you all know we have quite a lot of regressions recently, and recently they only add up to one another causing annoyances of testers and developers. There is a strong need to change this situation as soon as possible, otherwise the project's future is undetermined. I want to propose a step-by-step approach. Our brave testing team has created a good overview of the most important regressions and bugs we have so far: http://www.reactos.org/wiki/Buglist . Now, very important(!): For the first step I would like ALL developers to drop their current ReactOS-related work, including all work in branches or wherever else and focus ONLY on fixing regressions from that list. The goal is to fix all confirmed regressions that have been introduced, starting from the most recent and going down to the most ancient. All possible ways to remove a regression could be used: starting from a proper fix and finishing with a total revert or commenting out even good code. Process coordination: feel free to commit proper fixes right away, however as for reverts, I, and/or comittee of our core devs, would like to have a final say on whether something should be reverted. I repeat, all other non-regression related commits to the official ReactOS SVN repository are forbidden, even to branches. The only exception may be developers whose access is restricted to branches only. Thank you for understanding, Aleksey Bragin.

DecompressBitmap et alumni

You would convert these three to another > format like 32bpp, process them and convert back? No, of course not, Gregor, You're absolutely right about the 8bpp S/D/P situation. It would be a terrible idea to convert such a simple format to another for a tertiary rop. I think I was thinking about an internal graphic structure for the display context .. ;-) Accumulate all rops to an 32bit DIB internally, unless the physical device is low bpp. Come to think of it, almost anything but RLE is suitable internally, depending on the output color requirements. The graphics primitives for lines, ellipses, and so on can be small enough to separate a few specialized implementations for different bit depths. I guess that's what You do ? (I didn't look yet). Branching for different bit formats in the primitives would be a bad idea though.. Wouldn't You agree ? Best Regards // Love PS. I have a slice-line routine that's faster than an oiled lightning, and it's really small enough that it'd be worth replicating the code for different bit depths. Let me know if you're interested.

DecompressBitmap / Decompress4bpp / Decompress8bpp

by Love Nystrom

Hi guys, Sorry for barging in on a discussion about code that's not on my desk, but looking at your code there is something I want to point out. Graphics code need to be *fast*, that's a primary consideration, so I'm taken aback when I look at your inner bit expansion loop. This is horrible from a standpoint of performance. > length = (*bits++) >> shift; > if (length) > { > c = *bits++; > while (length--) > { > if (x >= width) break; > temp = UncompressedBits + (((height - y) * Delta) + x); > x++; > *temp = c; > } > } You're recomputing the start of the bit-run for every pixel you emit, when you should move that calculation out of the inner loop to get high performance. Graphics code is not the arena where you can be lazy and hope that the optimizer will make your inefficient code faster. At the very least You ought to write it something like this: > length = (*bits++) >> shift; > if (length) > { > c = *bits++; > if (x + length > width) { > // RLE encoding error - Bit-run exceeds width > length = width - x; > } > temp = UncompressedBits + ((height - y) * Delta); > x += length; // precompute finishing x > while (length--) > { > *temp++ = c; > } > } As a sideline note I'd like to mention that it's standard practice in graphics libraries to use one unified bitmap format internally to make internal processing like alpha-blend or text rendering or whatever straight forward. The 32bit DIB format is quite suitable, even if it uses the most memory - Graphics never was cheap on memory. Just my penny to the pot Best Regards // Love

Need to speak out

by Ros Arm

Hello, This is the second time that work that someone on the ARM Team has worked on has been mostly reverted without any communication with us, and incorrect changes have been added to parts of our work. The Eng function worked on even clearly stated comments such as "Compressed surfaces don't have scanlines!", yet this new patch restores the old incorrect functionality. lDelta cannot be anything but != 0 for compressed data such as RLE or JPG/PNG! And creating the DIB should not decompress the bits. Please read http://www.tech-archive.net/Archive/Development/microsoft.public.developmen… for example. I do not understand how you can believe that "RLE" has a scan-line. I am not a graphics expert by no means, but even I understand this fact: by definition scan-lines in an RLE are dynamic, and a scan-line offset table contains information about that. You do not have to take my word for it, as a simple driver test case will also show that Windows does not decompress RLE data or set lDelta to any other value than 0 with an RLE bitmap. You can find more information on RLE at http://www.fileformat.info/mirror/egff/ch09_03.htm. If you are wondering why there have not been any commits coming lately, recent actions such as these as the cause. -r Author: khornicek Date: Sat May 8 20:09:45 2010 New Revision: 47134 URL: http://svn.reactos.org/svn/reactos?rev=47134&view=rev Log: [WIN32K] - Bring back support for RLE compressed bitmaps. - Merge the decompress functions for 4bb and 8bpp bitmaps to one generic function. - Simplify SURFMEM_bCreateDib a bit by not allowing PNG/JPEG compression at all.

Server moves and upgrades

by Colin Finck

Hello everybody, We're currently in the process of moving a main server (Buildmaster, ISO-Storage, etc.) to another location and doing upgrades on the other servers. As always, we try to keep the downtime low, but expect short outages in the next few days. You'll be notified when the move is over or if there are any major problems. Best regards, Colin

Re: [ros-dev] [ros-diffs] [ekohl] 47071: [NEWINFLIB] - Change Unicode string functions from wcs* to str*W because glibc (Linux build) provides the wcs* functions but they use a wchar_t size of 32 bits instead of the required 16 bits. - Add a str*W to wcs* wrapper (infrosrtl.c) in order to use the wcs* function for the WIN32 build. - Add required str*W functions to the host library. ATTENTION: This might break the build bot although it has been tested on Windows and Linux!!!

The utf16_* family of functions in this file was particularly designed to address the issue of different wchar_t lengths on different hosts. It's meant to be used together with the include/host/wcsfuncs.h header. If you need an example, cmlib is one library using these functions (see e.g. "cmlib.h" for the proper header inclusion, "cminit.c" for a use, etc.) Best regards, Colin

crt wine sync

by Samuel serapion

Hey guys, Recently<http://source.winehq.org/git/wine.git/?a=history;f=dlls/msvcrt;hb=1ac163316…>wine has made some improvements to its msvcrt and I've taken the time to port them to reactos. changes include: - implement per thread crt locales and many locale functions. - implement/improve support for vc6, vc7, vc8 exceptions. - implement/improve language support functions. - implement/improve many library functions. - implement many secure functions. - use spec file for msvcrt.dll - fix amd64 linking issues. - add msvcirt.dll, msvcr7.dll ,msvc71.dll, msvc80.dll, msvcr90.dll from wine (no longer need to install versions of ms runtime for visual c language apps) changes are divided into different parts but building has not been tested with individual parts. part 1, 2 and 3 include changes to centralize the definition of several key macros (see reactos/wine/exception.h, reactos/wine/config.h, crt/include/internal/wine/cppexcept.h) also on part 2 in scanf.c wcs.c and possibly other files i didn't know what libcntpr expected so i was quite severe hacking out functions and only letting in the minimum necesary to build ntoskrnl and everything else that uses it. part3 includes changes to baseaddress.rbuild that should be revised, i didn't know how to calculate a good base address for the msvcr dlls so i just used the same one and let ntdll reallocate if necesary... part5 applies to rostests. and before you say it... msvcrt_winetest file now crashes with this trace: dll/win32/kernel32/file/create.c:136 (CreateFileW@28) <-- arch didn't check if lpFileName was valid lib/sdk/crt/stdio/file.c:1485 (_wsopen) modules/rostests/winetests/msvcrt/file.c:1179 (test_fopen_fclose_fcloseall)

[ros-diffs] [mjmartin] 47059: [win32k] - Fix a problem where application that used WH_CBT hook procedures were receiving destroy window notification on windows that were never created.

by James Tabor

Michael! Good work!!!! Do you think this might be one of the reasons we are reentering co_UserDestroyWindow? The DCE is cleared and (not cached) at first then we go back a second time and hit the assert...? http://www.reactos.org/bugzilla/show_bug.cgi?id=5320
