Re: ntdll: Use environment variable "WINESERVER" first on search for wineserver to start.

no, I Just replyed to all; fixed that

In the opposite having wineserver environment variable set in users environment will make it sure to always starts wineserver with the requested settings.
Well, you could also change $PATH globally to let "wine" point to your special wrapper executable. This would not really be different from using a global WINESERVER variable.
Really ? Adding an additional path looks more invasive in terms of security and maintenance as using a dedicated environment variable affecting only one executable.
I think there is a misunderstanding here, each wineprefix uses its own wineserver instance. Wineservers started for other prefixes will never inherit any timeout settings.
Thanks for this pointer, I wasn't aware of that.

With the mentioned patch applied to a local wine build (or with a renamed wineserver) the site now runs about two weeks and one noticable change is that the initial mentioned communication issue did not happens. This let me think that there may be a long time running issue with wineserver, which affects the dde interface.
It is nice that you have found a workaround, however we would also like to fix such issues of course. If you find any way to trigger this issue, please file a bug report.
I will do but unfortunally I'm not at this point yet. Observations from the last weeks shows that the error happened two times:
1. wineserver is running 12 days and not restarted because one application showed a message box, therefore did not quit and blocked wineserver restart, which let other wine applications dde communication fail 20170309-061102.523831920: starting '/srv/www/gauszweb-prod/tools/usr/bin/wineserver --foreground --persistent=3600 ' -> last wineserver restart 20170321-150057.967117185: starting '/srv/www/gauszweb-prod/tools/usr/bin/wineserver --foreground --persistent=3600 ' -> manual restarted because of application freeze
2. wineserver is running 3 days and applications dde communications fails because wineserver has been restarted immediatly 20170322-061003.064358739: starting '/srv/www/gauszweb-prod/tools/usr/bin/wineserver --foreground --persistent=3600 ' -> last restart .... 20170325-220751 -> print job starts 20170325-220753.202518273: starting '/srv/www/gauszweb-prod/tools/usr/bin/wineserver --foreground --persistent=3600 ' -> wineserver has been restarted by timeout 20170325-220805 applications dde communication fails and wine reports wine: chdir to /tmp/.wine-37002/server-fd0a-9602cwine: : No such file or directory chdir to /tmp/.wine-37002/server-fd0a-9602c : No such file or directoryThis is expected and not a bug. It can happen when multiple wine
instances try to start up wineserver at the same time. Only the first wineserver instance will be able to acquire the lock, all others will exit and then connect to the existing wineserver.
Sound reasonable
Best regards Ralf

- wineserver is running 12 days and not restarted because one

3. Yesterday we had a similar issue: dde communication of newly started applications fails after wineserver was running about 9 days because wineserver restart has been blocked by a still running application.
Currently it is not possible to say what happens in that incubation period and why it does affect dde comunication. We can only say that the main windows application (the engine which generates the graphics print out) has been started about 5000 times in the last ten days and the windows remote control application which uses dde to communicate with the main application runs between 10 and 356 times for each print out.
This indicates that any long time usage of a wine application for example as server backend using dde may have similar issues. Would it be possible to restart wineserver although applications are still running ?
- wineserver is running 3 days and applications dde communications
fails because wineserver has been restarted immediatly ... applications dde communication fails and wine reports wine: chdir to /tmp/.wine-37002/server-fd0a-9602c failed: no such file or directory
The related part is located in server_connect() (see https://source.winehq.org/git/wine.git/blob/HEAD:/dlls/ntdll/server.c#l1210)
1210 setup_config_dir(); 1211 serverdir = wine_get_server_dir(); 1212 1213 /* chdir to the server directory */ 1214 if (chdir( serverdir ) == -1) 1215 { 1216 if (errno != ENOENT) fatal_perror( "chdir to %s", serverdir ); 1217 start_server(); 1218 if (chdir( serverdir ) == -1) fatal_perror( "chdir to %s", serverdir ); 1219 }
Guessing from the error message "no such file or directory" I would say that the error happens in line 1218, which indicates that the server could not be started
Any ideas what could happen here ?
