The purpose of my question was to make sure that wherever we are doing changes to the product code to work-around limitations in Wine, we are doing so only when running on Wine. And, before you (or anyone else) send further flame mail, note that we are submitting fixes to Wine as and when we run into them and have a solution. We are not trying to limit the product in anyway on Linux - if any, we are trying to make sure that the end-user experience for our product when running on Linux is as painless and seamless as possible. So, stop being so paranoid! == Raghavan -----Original Message----- From: Joshua Walker [mailto:halkun2002(a)yahoo.com] Sent: Thursday, June 10, 2004 5:13 PM To: wine-devel(a)winehq.com Subject: Re: How to determine if an application is running in Wine environment?

Looking for developers: processing of Windows EMF files for CUPS, NX, Samba and Freedesktop.org printing
by Fabian Franz June 11, 2004

June 11, 2004

Hi, my name is Fabian Franz. I am usually hacking for Knoppix. Recently Kurt showed me NX/NoMachine.com. You can read some more about NX/NoMachine here: http://www.linux-kongress.org/2003/abstracts/index.html#3_7_2 http://www.nomachine.com/ 'X from NoMachine makes remote GUI connections faster than ever before, especially over lo-bandwidth/hi-latency links. The remote session can be initiated from all major workstation OS-es (Linux, Windows, Mac OS X, Solaris) and even PDAs (Zaurus, iPAQ). They can connect truely cross platform to Unix-Linux/X11, Windows/RDP and "anything"/VNC. A modem link a mere of 40 KBit/sec gives a very comfortable working speed for a KDE desktop running Konqueror (file manager), OpenOffice (word prozessor), Mozilla (web browser) and KMail (email client). This type of NX link is faster to work with than a DSL link with 384 kBit/sec using vanilla X11 over "ssh -X -C".' I was fascinated so much by this sofware, that I did some research. I noticed that it doesnt yet support printing ... You are not be interested in the use case I describe next? But you stll find the research useful? Then just skip to "===" The Use Case ----------------- With NoMachine I have the possiblity to use my machine at home (Windows, Linux) from anywhere and from every OS platform (Linux, Windows, Solaris, Zaurus, iPAQ, Knoppix) with maximum speed. Even with just 16 kbit/s upstream, it has nice performance. I login and can work on my machine, with my files and everything is good. :-) Now I want to print something. I have attached my local printer to my notebook and want to print from my remote Linux session. If my notebook is running linux, everything is fine. The CUPS on the remote side is sending the untouched data ("raw printer driver") to the CUPS on my side. The local CUPS parses the format, prints with the local driver and my printer prints. So I did not have to configure _anything_ on the remote CUPS daemon. It just works out of the box. Now change the scenario. Assume that now I had to boot my notebook into Windows. The locally attached printer may be proprietary.... So even if I could configure CUPS on the remote side, it still would have no driver to print to Windows. Windows would pass whatever it gets to the printer and the printer would in the best case say "I don't understand this" or print garbage. But there is one file format every Windows printer driver accepts as input (and converts it into the format of his target printer): it is called EMF (Enhanced MetaFile). If we could make sure that we send correct EMF to Windows, we had a guarantee that it would finally be printed. In fact, one of the central jobs of any Windows printer driver is to convert EMF into printer specific data. The task to "reverse engineer" EMF and create a Linux program that outputs EMF for printing seems to be too complicated at first. In priciple Windows records all commands that draw something and writes it to a (temporary) file. This was done to allow an application to just pass the data to Windows and then return back to normal operation. If "direct printing" is enabled, the application would have to wait for the printer to finally accept the last page. This spooling can be used to get hold of EMF files for analyzing. It should be noted that EMF is encapsulated then into a *.SPL spool file, which can contain several EMF-files and a printjob title. For more information and a really nice diagram see: http://www.printlogger.com/support/articles/msdn/3/index.html You can also get much information directly from Microsoft or other websites. Just use google ;-) Wouldn't it be nice, if I just printed on my remote session and then Windows would use its native driver? I would print on my remote session with CUPS and CUPS would create EMF (device independent extended metafile) and that EMF would be spooled to a SPL file and that SPL file would be transferred to my local Windows box printer and from there it would use the native driver to print my document. === The Task ----------- Spooling EMF to Windows ()instead of raw) to allow usage of the native printer driver ... First it sounds really easy to do. But then you find many problems at second sight: The Problems ----------------- - There is no program to convert ps to EMF on Linux. - The MS spool format is proprietary and not easy to understand. (This format is called SPL) But both of these are wrong: EMF Creation ----------------- For converting ps to EMF you can use either: - libEMF.sf.net and pstoedit or - OpenOffice.org :-) While libEMF does only implment a subset of the EMF-fileformat and is optimized for graphics, OpenOffice.org's EMF-Output is of perfect quality. Kudos to the guys from Star Division, who I believe did this initial job. (If I am wrong, please correct me) So, the first problem is almost solved. Almost, because OpenOffice cannot import PS (postscript) or any other vector based fileformat, we have on linux. But I am sure there are possibilitites, to solve these issues: Either implement OpenOffice PS-import (We'll need it anyway sooner or later) or to extract the EMF-Filter from OpenOffice.org and build it into some PS-Application. Ok, now to the second problem. SPL File Format -------------------- - SPL format is proprietairy. Well, yes. Microsoft gives no information whatsforever about this format, as it is due to change in a new version. Well, but when SMB / CIFS was implemented I believe it did also change from Release to Release, didn't it? Fortunatley there are already some "hackers", who have done substantial work on the SPL-fileformat, so that its now "known". Well, but let me start from beginning. The day before yesterday morning I started my research again, after I got an email from Wolfgang Glunz, author of pstoedit, saying that EMF was not like the Windows spool-format spl. So I did some google-groups reseach and I found posts from Feng Yuan. He explained that spl was just a small aditional header before and after the EMF pages. Programming resources ----------------------------- He also pointed to his website http://www.fengyuan.com. Guess what, Feng Yuan even did write a book about Windows GDI programming and also had a very nice EMF-test-application included. If you want to experiment with EMF, get that EMF.zip: It is really worth it. It can even read spl files directly. And it prints out the different GDI-commands to print the image, so you can also check the "quality" of your EMF-creation tool. (I'll try to get the book at our local computer science library (If I can trust the internet it should be there ;-) ) to look up the chapter about printing) You can "force" your local printer to spool to EMF first and to keep the spooled files. (You have to use "EMF NT 1.8" instead of RAW in one of the advanced pages and also tick another checkbox to keep the spooled files) Once I got that spooled spl file, I did look at it with "edit" in binary mode and did remove the spl header. And the (one page) spl-file was converted to EMF! What is really nice is, that as I already mentioned, the "hackers" from http://undocprint.printassociates.com/spooler/spoolfiles/spl/ did write up, what they do know about the spl format and that should be enough to parse or create spl files from / to EMF. "Print Mirror" ---------------- And there is also another very interesting link to some "hacker", who published an article on the msdn how to extract EMF files from the spl files. But not enough, he even started an open source project under the GPL (!) for a print mirror utility, that allows one to save the EMF data from the spool files. http://www.angelfire.com/extreme4/vprint/ While it could be a very practical tool to create EMF -> SPL and vice versa converters, I also could imagine that having sample GPLed printer code could be useful for other developments too. (You'll need the DDK (MS VisualStudio DDK (Driver Development Kit)) to compile it, though) Sources ---------- I have attached some sources I wrote today from the undoc-printing specification (You'll need libwine-dev to compile them). Thanks go to Christoph Lindemann for publishing that information. spl_info.c could be easily extended to allow extraction of EMF-files, I just was too lazy to do it. spl_create.c can create valid spl-files from one or more EMF-files. I tried using an EMF made by OpenOffice.org under linux and spooling that one to Windows through normal kprinter / cupsdoprint / smbspool operation. Guess what? Windows did use the native driver installed on the machine. As I did use some printer that prints to "FILE", I could see that the output indeed was "HPs Adobe Postscript". So my initial idea indeed does work. "Experiments" and next steps ------------------------------------- For first experiment see "sources" above ;-) Even one step further would be to integrate and experiment with that technology in Samba smbspool some more. (Jerry Carter from the Samba Team mentioned it could be interesting to change to RPC instead of SMB for that). One could also try to enhance libEMF to allow the whole EMF-"standard". (Well, WINE GDI libs and OpenOffice.org source could help) You can find an overview of EMF at MSDN: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/metafi… - An Overview of the Extended METAFILE Structures. Or / And to add ps-import to OpenOffice.org. While pstoedit is nice, the font creation with the current sdl is charcater for character, which is not exactly the best for printing ;-) - especially if you have such an powerful library as GDI. Do something cool with "Print Mirror". I for exmaple could imagine that testing is much easier that way, as you can directly see the results. Conclusion -------------- I believe, when one would combine the results of this "technology analysis", it would be possible to: - Allow spooling of EMF for Samba to accept (Dunno if there are szenarios, where this would have advantages) - Allow a CUPSd to send EMF data to Windows and let Windows use the local printer driver. (for the use case mentioned in the beginning) - With the "PrintMirror" it might be possible to force creation of EMF, as its not always done, yet. Even if Microsoft decided to change the format of SPL, one could support, I believe 3.x/95/98/ME/NT/2000/XP/2003, which should suffice for the next years ;-). Thanks also go to Kurt Pfeifle for reading and helping with this document. All discussions should CC one mailing list and I would propose samba-technical for that. cu Fabian "Bibliography": http://www.linux-kongress.org/2003/abstracts/index.html#3_7_2 - Explanation of NX / NoMachine by Kurt Pfeifle. http://www.nomachine.com/ - Terminalserver with very efficient compression to allow usage over low-bandwidth links http://www.printlogger.com/support/articles/msdn/3/index.html - Diagrams that explain the Windows Spooling Process http://libEMF.sf.net - Library, which can create EMF together with http://www.pstoedit.net http://www.fengyuan.com - Book and sample EMF application http://undocprint.printassociates.com/spooler/spoolfiles/spl/ - The SPL file format http://www.angelfire.com/extreme4/vprint/ - Open Source "Print Mirror" EMF extraction utility. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/metafi… - An Overview of the Extended METAFILE Structures.

Zombie processes
by Shachar Shemesh June 9, 2004

June 9, 2004

Hi all, Mike M told me on IRC that this matter has come up before, but I have not been able to find it in the archives. It seems Wine has been generating lots of zombie processes when it's not 100% cleanly killed. I have also seen the system hold a socket created from a wine process in "ESTABLISHED" state, when no process is registered as the socket's owner. According to Alexandre according to Mike, this is a kernel bug. Well, it most certainly is. Theoretically, there is nothing a user space process can do to cause zombies to stay around after their parent has exit, or keep sockets open after their controlling process has quit. As wine is a user space only process, this must be a kernel bug. No way around it. However, it happened to me both on RedHat 9 with 2.4.something (NPTL back ported), with both RH9's original kernel, and their most up to date one. It also happened on Debian Sid's almost-vanilla kernel 2.6.6. It happened with LD_ASSUME_KERNEL=2.4.1 making wine choose the standard threading mode, as well as without, choosing nptl. The zombies are sometimes called wine-pthread/wine-kthread, and sometimes wine-preloader. In short, I think this is a long standing Linux kernel bug, and Linus helps those who help themselves. I will also not be surprised if it was triggered by a wine bug. So the question is this. Is there anyone on this list who knows how to submit this as a question to lkml? The only time I tried to do anything remotely like it, I was seriously ridiculed. I understand from friends that live there that this is not an exceptional thing, so I'm a bit hesitant to go back there. If no one else does, however, I will. It will require me to untaint my kernel, so someone please save me from the slow armagatron I get when I'm not running nvidia, and report this :-) Will someone take this task on himself?

Linux links in Windows

Hi I have a question about the standard drive/directory. I think there were some changes recently so I don't know the current state. I'm still on 20040408 as we needed to freeze and test the source. I have a process which changes the current dir and then starts a new program with CreateThread. But this one is back in the old dir again. Shouldn't it inherit the current dir of the starting process? Is this already in the current wine? Thanks bye Fabi
