Threading issues? [ck-request@vds.kolivas.org: ck Digest, Vol 3, Issue 16]
by Andreas Mohr Aug. 20, 2004

Aug. 20, 2004

Hi all, this is a nice little posting from the Con Kolivas Linux interactivity patches list. Note that it is about Cedega, not Wine, but it might easily affect Wine, too. Are we doing some big no-nos in the threading area here? (or maybe it's just done the way it is because we cannot do it a different, better way?)

Thanks for details. You do not have different nice levels; that is PRI that is different, which is the "dynamic" priority that constantly changes by the scheduler. It is as I suspected, though - if you renice everything +19 and the problem goes away it is bad programming on the wine developers' part that use what's called sched_yield instead of proper locking between their threads. Don't concern yourself over the details, but at least you have a simple workaround... sigh Cheers, Con

Re: Different X Displays and Wine
by Eric Frias Aug. 20, 2004

Aug. 20, 2004

Alexandre Julliard (julliard_at_winehq.org) wrote:> We don't support having the same user run from different displays at> the same time. I don't think that's a common setup at all. It probably is not a common setup, but Boaz isn't the only person to have been bitten by this. It has happened both to us and to people who use our software. In our development environment, we usually use one or two common user accounts to do all development and testing in. I know this isn't ideal, but I don't have any power to change this. Anyway, with this setup, it is very easy to have two people developing or testing from the same account but displaying on separate machines. Right now we have been doing what was suggested earlier -- we have a script to launch our application and this script creates a .wine-$DISPLAY directory and points WINEPREFIX to that directory. This works well enough for now. It's inconvenient that the config file and registry aren't shared, so doing things like changing printer settings is a bit of a chore, but this hasn't bothered us too much yet. We're also making the assumption that not many users will be running this on multiple displays, so things will just work for most users and the few that do try to run on multiple displays will at least be able to do it. I'm curious how much work would be involved in fixing this correctly. I've never looked at the wineserver code, so I don't know if this would just be a matter of adding another variable to a data structure that gets passed around to all of the windowing code, or if this would require major changes to the way wineserver works. If it's reasonably easy, I might be able to make the fix or lend some assistance; if it is a large amount of work, we'll probably be happy with the workaround we have. Eric

As most of the read/write structures are thread-dependent, I don't really see how two threads could thrash their data, except for some buffer overflow, hence my first question. A+

Hi Eric, I have tried the updates but to no avail. I have a test program that appears to work well. However when that code is used in my project I still lose some characters at the end of the message. The main difference is that my project uses sockets, in another thread, to transfer the read/write data to/from another application. Could the results from the socket calls be messing with the ReadFile() results? I will make an example program that includes sockets to see if I can verify this. regards, scott. > -----Original Message----- > From: Eric Pouech [SMTP:pouech-eric(a)wanadoo.fr] > Sent: Thursday, 19 August 2004 3:14 > To: Scott Snell > Subject: Re: Adventures in serial port. > > Scott Snell a écrit : > > Fantastic!

Re: Let StartServiceCtrlDispatcher handle services started other than with StartService (with patch)
by Alexander Yaworsky Aug. 20, 2004

Aug. 20, 2004

I think that this is incorrect. If you let StartServiceCtrlDispatcher to continue with no error, you make calling program think that it is running under control of service control manager. When service program handles somehow any kind of its launching, the behaviour may be quite different. Also, under windows StartServiceControlDispatcher always fails if service program is started not with StartService (maybe we should add 15 seconds delay to exactly emulate versions earlier than XP? ;-))).

poll vs. epoll
by Shachar Shemesh Aug. 19, 2004

Aug. 19, 2004

Hi all, I have a program (a server) that has a very large number of synchronization constructs. Even when everything is idle there, wineserver is taking 60% of the CPU, raising load average to 2.4. When load is applied, response time occasionally jumps from tenths of a second to two minutes. I noticed that in server/fd.c, the wineserver is using "poll" to select between file descriptors. The application is going through this code over 2000 times a second, with over 380 file descriptors each time. I am wondering whether this can be the cause of the slowdown. One of the possible solutions to this would be to use epoll instead. This, of course, would have to be backed by a configure check, as not all systems for which wine is intended support epoll. Another, arguably better, solution would be to use libevent for this purpose. Libevent has the distinct advantage that it automatically chooses the best tool for the job (epoll, poll, /dev/poll, or if all else fails, select). However, if there is another, independent use of poll, porting the semantics to libevent may prove non-trivial. So what does the forum think? One last question. What are the "users"? What constructs cause a new file descriptor to be allocated in the wineserver? Shachar -- Shachar Shemesh Lingnu Open Source Consulting ltd. http://www.lingnu.com/
