[Bug 904] New: - Solaris: Add threading support

http://bugs.winehq.com/show_bug.cgi?id=904 Summary: Solaris: Add threading support Product: Wine Version: CVS Platform: PC OS/Version: Solaris Status: NEW Severity: normal Priority: P2 Component: wine-ports AssignedTo: wine-bugs(a)winehq.com ReportedBy: fgouget(a)codeweavers.com Threading does not work correctly on Solaris (an issue for both x86 and Sparc platforms). The reason is that Linux (and FreeBSD) treat threads differently from Solaris. * on Linux a process can contain multiple threads and each thread gets a unique system-wide identifier which is confusingly called a pid (process id). It can be argued that Linux does not in fact have the notion of what a process is: there is no object that represents the process that contains all these threads. So you cannot kill a process, you can only kill its individual threads. This is because you can only send signals to specific threads so that when you 'kill -9 pid', you only kill one individual thread in the process. * on Solaris too a process can contain multiple threads (called lightweight processes or lwp for short). However, processes and threads are each separate system objects. When you send a signal it is sent to the process: 'kill -9 pid' will kill the process and all its threads. Also, individual lwps do not have a globally unique identifier. Instead their ids (typically 0, 1, 2, etc.) are only unique within a process. So if you want to refer to a specific lwp in the system you must use specify both the pid and the lwpid. Wine and in particular the Wine server, need the following functionality: 1. uniquely identify a thread in the system 2. sending a signal to a specific thread 3. precisely identifying a thread's parent thread (for handle inheritance when creating a new process, etc. It is a prerequisite for the debugger too) See the following files for reference: * server/process.c server/process.h Where the wineserver keeps track of Windows processes * server/thread.c server/thread.h Where the wineserver keeps track of Windows threads * scheduler/client.c Called by a new Windows thread to register itself * scheduler/process.c Called by a new Windows process to register itself * include/wine/server_protocol.h Defines the structures used for the wineserver protocol Then, to identify a thread uniquely we can: * add a unix_pid field to the 'struct process' in server/process.h * rename the 'unix_pid' field in 'struct thread' to 'unix_tid' in server/thread.h * on Linux, set unix_pid=0 and unix_tid=getpid() * on Solaris, set unix_pid=getpid() and unix_tid=_lwp_self() * make sure we do not write code that would identify a process by its unix_pid (would be a tempting thing to do on Solaris but does not work on Linux) * use both unix_pid and unix_tid whenever we need to identify a thread (i.e. find its struct thread structure) To send a signal to a specific thread, the solution is to use the procfs: Open /proc/<pid>/lwp</lwpid>/lwpctl and write two ints: PCKILL followed by the signal id. Do a man -s 4 proc or find it online at: http://www.cs.princeton.edu/cgi-bin/man2html?proc:4 Identifying a thread's parent is harder because there is no lwp_getppid() function. So I propose the following trick: * just before creating a new process (in fork_and_exec), set the WINE_PARENT_LWPID environment variable to "pid:lwpid" * during the process initialization check for the WINE_PARENT_LWPID environment variable and reset it right after use * if set, make sure that the pid matches our ppid. If so, then the information it contains is valid and the lwpid is the id of our parent lwp (which means wrapper scripts must _exec_ wine) * if the pid does not match our ppid, then this is a stale environment variable: a Wine process must have started a Unix process, which in turn launched another Wine process. But the Unix process is our parent, not the Wine process so there are no handles to inherit anyway. * if the variable is not set, then this Wine process was started from Unix so there is nothing to inherit DO NOT REPLY TO THIS EMAIL, BUT PLEASE POST YOUR BUG RELATED COMMENTS THROUGH THE WEB INTERFACE AVAILABLE AT <http://bugs.winehq.com/show_bug.cgi?id=904>.

[Bug 900] - Upgrade from 20020605 to 20020710 broke Orcad Caputre Support
by wine-bugs＠winehq.com July 21, 2002

July 21, 2002

http://bugs.winehq.com/show_bug.cgi?id=900 ------- Additional Comments From tony_lambregts(a)telusplanet.net 2002-07-21 12:23 ------- Out of curiosity how old is your computer? I do regression testing all the time on mine. P233 with 96 mb RAM and 40GB hardDrive. I did regression testing with a 3GB harddrive and 32 mb ram using the same computer. Yes it is time consuming but you can use your computer while it is doing a compile. With the timeframe you are talking about it should take at most 6 itinerations to narrow it down to the day the patch was applied.

This is the version I used. I have a relatively old computer, so regression testing would be very very time consuming. However below is the url to the form to get a copy of the cd for anyone willing to help. http://www.cadencepcb.com/products/downloads/orcaddemo/frmorcaddemocd.asp DO NOT REPLY TO THIS EMAIL, BUT PLEASE POST YOUR BUG RELATED COMMENTS THROUGH THE WEB INTERFACE AVAILABLE AT <http://bugs.winehq.com/show_bug.cgi?id=900>.

[Bug 889] - WINPOS_GetWinOffset() yields wrong offset
by wine-bugs＠winehq.com July 21, 2002

July 21, 2002

http://bugs.winehq.com/show_bug.cgi?id=889 ------- Additional Comments From tuiningas_ml(a)shaw.ca 2002-07-21 00:26 ------- I followed the trail a little bit further as I noticed that "hot spots" on an image (like buttons) would fade in and out when the window wasn't at the top left of the screen. The trail led to the file dlls/x11drv/winpos.c. It is making a call to MapWindowPoints() which in turn calls WINPOS_GetWinOffset(). If I eliminate the call to MapWindowPoints() in the function expose_window() at line 290, (and restore the original version of windows/winpos.c) everything works beautifully. The window draws itself properly and the buttons work as expected. I am not all that familiar with Wine code, though, so can anyone think of a good reason why this code ought to be there? Should I submit a patch? And if so, can anyone point me to the method required for doing so? Thanks.

http://bugs.winehq.com/show_bug.cgi?id=901 ------- Additional Comments From tony_lambregts(a)telusplanet.net 2002-07-20 23:08 ------- Well the first thing you should do is get a newer version of wine http://www.winehq.com/download/ I recommend installing from tarball. This isn't to hard to do if you follow the instructions in the README file. Also have a look at the wine users guide. http://www.winehq.com/Docs/wine-user/ DO NOT REPLY TO THIS EMAIL, BUT PLEASE POST YOUR BUG RELATED COMMENTS THROUGH THE WEB INTERFACE AVAILABLE AT <http://bugs.winehq.com/show_bug.cgi?id=901>.
