[Bug 33642] New: Microsoft SQL Server Management Studio Express 2005: restarting SQL server fails randomly
http://bugs.winehq.org/show_bug.cgi?id=33642 Bug #: 33642 Summary: Microsoft SQL Server Management Studio Express 2005: restarting SQL server fails randomly Product: Wine Version: 1.5.30 Platform: x86 URL: http://www.microsoft.com/download/en/details.aspx?id=8 961 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wmi&wbemprox AssignedTo: wine-bugs(a)winehq.org ReportedBy: djelinski1(a)gmail.com Classification: Unclassified Now that Bug #33607 is out of the way, it is possible to restart SQL Server service. The application first stops the service, then checks if it is stopped, and if it is, tries to start it. Starting the service quite often throws an exception, and stack trace reported by the application points to wbemprox.
From the initial investigation it seems to me that calling StartService temporarily invalidates all existing instances of the service object. Here one thread tries to get SystemName property from the object while another thread tries to restart the service, and getting property throws an exception.

It assumes that the installers are downloaded to correct locations, so it needs some tweaking before use. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

http://bugs.winehq.org/show_bug.cgi?id=33642 --- Comment #3 from Daniel Jelinski <djelinski1(a)gmail.com> 2013-06-05 02:54:25 CDT --- Hello Hans, Thanks for looking into this. Unfortunately, the recent commits in wbemprox didn't help. Comment 1 above referred to version with "wbemprox: Add a function to resize a table" and "wbemprox: Rewrite IWbemServices::ExecMethod with low-level functions so we can reuse the object instance" already applied. Also, sometimes restarting does not throw exception, but instead shows garbage in place of system name and service name. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Basically one thread attempts read data from table just after another thread (calling StopService) clears the table. Since the table is shared between all objects of the same type, this fails. Global variables causing trouble again... -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
