Application Verifier - Stop Codes - Printing

The following stop codes are contained in this set of tests.

Leaked printer handle detected

Probable cause

An open printer handle was detected when the application terminated. Most likely, the creating thread did not call ClosePrinter() to close the printer handle. To troubleshoot this stop, determine the thread that opened the printer handle by using the second parameter of this verifier stop to provide the stack trace. Dump the stack trace using the dps command in the debugger. Find the first non-winspool and non-vfPrint module name that called vfPrint!VfHookOpenPrinter* or vfPrint!VfHookAddPrinter* - this typically is the 4th or the 6th stack frame in the list.

Information displayed by Application Verifier

• Parameter 1 - Printer handle being leaked.
• Parameter 2 - Initialization stack trace. Use dps to dump the stack if this parameter is not NULL.
• Parameter 3 - Thread id of the thread that opened the handle.
• Parameter 4 - Not used.

Additional Information

Leaked printer change notification handle detected

Probable cause

A printer change notification handle that was not closed was detected when the application exited. Most likely the thread that opened the handle did not call FindClosePrinterChangeNotification() to close the handle before the thread exited. To troubleshoot this stop, determine the thread that opened the printer change notification handle: The second parameter of this stop provides the stack address. Use the dps command to dump the stack trace. Find the first non-winspool and non-vfPrint module name that called vfPrint!VfHookFindFirstPrinterChangeNotification. This is typically found in the 4th stack frame.

Information displayed by Application Verifier

• Parameter 1 - Printer change notification handle being leaked.
• Parameter 2 - Initialization stack trace. Use dps to dump the stack trace if it is not NULL.

Leaked PRINTER_NOTIFY_INFO detected

Probable cause

An allocated PRINTER_NOTIFY_INFO object that had not been freed was detected when the program exited. Most likely, it needs to be freed by calling FreePrinterNotifyInfo() before exiting. To troubleshoot this stop: Determine the routine that called winspool to allocate the PRINTER_NOTIFY_INFO object on its behalf by using the second parameter of this verifier stop. Dump the initialization stack trace using the dps command in the debugger. Find the first non-winspool and non-vfPrint module name that called vfPrint!VfHookFindNextPrinterChangeNotification. This routine is typically found in the 3rd stack frame.

Information displayed by Application Verifier

Race condition detected while using a printer handle

Probable cause

A printer handle is being used concurrently in multiple threads. Printer handles are not thread safe which means that simultaneous use of a printer handle in multiple threads is not permitted without application-level synchronization to safely coordinate access to the handle. The application should either open a separate printer handle in each thread or provide custom synchronization access to the printer handle by using the Win32 synchronization API. The Win32 synchronization API is described further at https://learn.microsoft.com/windows/win32/sync/synchronization-functions.

Information displayed by Application Verifier

• Parameter 1 - Printer handle being accessed.

Async Notify handle returned by RegisterForPrintAsyncNotifications was not released properly

Probable cause

Handle allocated by RegisterForPrintAsyncNotifications API function had not been released until the program exited. Most likely, it needs to be released by calling UnRegisterForPrintAsyncNotifications() before exiting. To troubleshoot this stop: Determine the routine that called winspool to allocate the handle on its behalf by using the second parameter of this verifier stop. Dump the initialization stack trace using the dps command in the debugger. Find the first non-winspool and non-vfPrint module name that called vfPrint!VfHookRegisterForPrintAsyncNotifications. This routine is typically found in the 3rd stack frame.

Information displayed by Application Verifier

IPrintAsyncNotifyChannel contract violation by the operating system.

Probable cause

The platform implementation of IPrintAsyncNotifyChannel violated part of the special contract implied or defined by IPrintAsyncNotifyChannel. IPrintAsyncNotifyChannel has special exceptions to AddRef and Release. This requires that the platform calls OnEventNotify and ChannelClosed with the same pointer value as the channel was created with.

IPrintAsyncNotifyChannel contract violation by channel consumer.

Probable cause

On bidirectional channels, calling SendNotification, CloseChannel, or making the final Release on the interface pointer relinquishes 'ownership'. After creating the channel and sending the first notification, you cannot call Release() until your callback's OnEventNotify is invoked. If either you invoke CloseChannel() or get a ChannelClosed notification, then you must not perform the final Release() call.

Invalid number of supported Print Schema major versions

Probable cause

The PrintTicket provider plug-in returned an invalid number of supported Print Schema major versions. The IPrintOemPrintTicketProvider::GetSupportedVersions method in the plug-in is expected to return at least one supported major version. Because Windows Vista supports only one major version of the Print Schema, the plug-in is expected to return a value of one.

Missing supported Print Schema versions

Probable cause

The PrintTicket provider plug-in indicated that it was returning at least one supported Print Schema version but failed to return any. The call to the IPrintOemPrintTicketProvider::GetSupportedVersions method in the plug-in accepts two out pointers as arguments. The ppVersions argument points to an array of integers representing the supported major versions of the Print Schema. The cVersions argument points to the number of elements in the array of integers that is being returned. This verifier stop occurs when the plug-in returns a valid number in cVersions but fails to return anything in the ppVersions array.

Invalid OEMPTOPTS value

Probable cause

The PrintTicket provider plug-in returned an invalid OEMPTOPTS value. One of the arguments to the IPrintOemPrintTicketProvider::BindPrinter method in the plug-in is a pointer to an OEMPTOPTS enumeration. The plug-in is expected to set the value of this argument to one of the values supported by Windows Vista. The values supported by Windows Vista are OEMPT_DEFAULT and OEMPT_NOSNAPSHOT. This verifier stop occurs when the plug-in returns a value that is not one of these supported values.

Missing Print Schema private namespace

Probable cause

The PrintTicket provider plug-in indicated that it was returning at least one Print Schema private namespace but did not return any. The call to the IPrintOemPrintTicketProvider::BindPrinter method in the plug-in contains two out pointer arguments through which the plug-in can return information about the Print Schema private namespaces that it supports. The ppNamespaces argument points to an array of strings representing the supported Print Schema private namespaces. The cNamespaces argument points to the number of elements in the array of strings that is being returned. This verifier stop occurs when the plug-in returns a valid number in cNamespaces but does not return anything in the ppNamespaces array.

Incorrect reference counting detected in the plug-in

Probable cause

The WDK states that plug-ins must perform accurate reference counting in their implementation of the IUnknown::AddRef and IUnknown::Release methods. The lifetime of the plug-in's interface object depends on accurate reference counting. If the reference counting is inaccurate, it can result in a resource leak or lead to the premature unloading of the plug-in which will cause the driver to fail. This verifier stop occurs when incorrect reference counting is detected in the plug-in.

The plug-in returned a NULL PDEV after returning S_OK from the EnablePDEV method

Probable cause

The private PDEV returned by the plug-in was NULL although the return value from the EnablePDEV method was S_OK indicating success. The WDK states that if the EnablePDEV method of a plug-in returns a status of S_OK, it must also allocate an instance of its private PDEV structure, initialize it, and return the address of this structure in the method's pDevOem parameter. This verifier stop occurs when the plug-in does not return a valid private PDEV structure when from its implementation of the EnablePDEV method returns a status of S_OK.

The plug-in returned a private DEVMODE that is smaller than the minimum size allowed

Probable cause

The private DEVMODE returned by the plug-in should be at least the size of OEM_DMEXTRAHEADER. The DevMode method of a plug-in must return the size required to store its private DEVMODE members when it is called with the OEMDM_SIZE mode. This value is set the first time the method is called. The DevMode method in the plug-in must set the value of the cbBufSize member in the OEMDMPARAM structure to the number of bytes needed and that value must be greater than or equal to the size of OEM_DMEXTRAHEADER. This verifier stop occurs when the size returned in the cbBufSize member in the OEMDMPARAM structure is less than the size of OEM_DMEXTRAHEADER.

Information displayed by Application Verifier

• Format: - This verifier stop was caused by the plug-in module at %lS

The plug-in returned a private DEVMODE with a different size than the size returned by the DevMode(OEMDM_SIZE) call

Probable cause

The plug-in should return a private DEVMODE with a size that is the same as that returned by the DevMode call with OEMDM_SIZE mode. The DevMode method of a plug-in must return the size required to store its private DEVMODE members when the DevMode method is called with the OEMDM_SIZE mode. This value is a constant and is set the first time the method is called. It must not change when subsequent calls are made to the plug-in's DevMode method. This verifier stop occurs when the DevMode method in the plug-in returns a value that is different from the value it returned the first time it was called.

A call to a printer driver changed the security context.

Probable cause

This stop usually occurs when a print driver calls either RevertToSelf() or RevertToPrinterSelf() but did not change the security context back to impersonating the user by calling ImpersonatePrinterClient(). This is not allowed and print spooler behavior is undefined after this happens. This can also create a security vulnerability and allow a remote authenticated elevation of privilege type of attack.

A print driver called ExitThread

Probable cause

A print driver module called ExitThread. When a print driver module calls ExitThread, the thread is exited before any destructors can be called or any other automatic cleanup can be performed. This can lead to undefined behavior. Therefore, print drivers should always return from their thread function. To troubleshoot this stop: Dump the current stack trace by using the 'k' command in the debugger to identify the routine that invoked ExitThread.

Information displayed by Application Verifier

• Parameter 1 - Not used.
• Parameter 2 - Not used.
• Parameter 3 - Not used.
• Parameter 4 - Not used.

A print driver called TerminateThread

Probable cause

A print driver module called TerminateThread. TerminateThread is used to cause a thread to exit. When this occurs, the target thread has no chance to execute any user-mode code. DLLs attached to the thread are not notified that the thread is terminating. The system frees the thread's initial stack. TerminateThread is a dangerous function that should only be used in the most extreme cases. For example, TerminateThread can result in the following problems: - If the target thread owns a critical section, the critical section will not be released. - If the target thread is allocating memory from the heap, the heap lock will not be released. - If the target thread is executing certain kernel32 calls when it is terminated, the kernel32 state for the thread's process could be inconsistent. - If the target thread is manipulating the global state of a shared DLL, the state of the DLL could be destroyed, affecting other users of the DLL. To troubleshoot this stop: Dump the current stack trace by using the 'k' command in the debugger to identify the module and routine that invoked TerminateThread.

Information displayed by Application Verifier

• Parameter 1 - Not used.
• Parameter 2 - Not used.

Print filter changed the COM apartment type for the current thread.

Probable cause

This verifier stop occurs when a print filter changes the COM apartment type in one of its methods (InitializeFilter, StartOperation, or ShutdownOperation). Use the 'ln poi(<Param1>)' command in the debugger to identify the name of the print filter DLL.

Information displayed by Application Verifier

• Format: -  This verifier stop was caused by a print filter's %lS method changing the COM apartment type from %lS(%d) to %lS(%d).
• Parameter 1 - Filter interface pointer. Use 'ln poi(<Param1>)' to find the filter.
• Parameter 2 - Expected apartment type
• Parameter 3 - Actual apartment type
• Parameter 4 - Not used.

Additional Information

• Test Layer: PrintDriver
• Stop ID: COM_APARTMENT_TYPE_CHANGED

COM is not initialized for the current thread after call to print filter method.

Probable cause

This verifier stop occurs when a print filter has unbalanced CoInitialize[Ex] and CoUninitialize calls. This could be due to CoInitialize[Ex] unexpectedly returning failure, such as when the request apartment type does not match the thread's current type. Use the 'ln poi(<Param1>)' command in the debugger to identify the name of the print filter DLL.

Information displayed by Application Verifier

• Format: -  This verifier stop was likely caused by a print filter's %lS method calling COM's CoUninitialize without a corresponding successful CoInitialize[Ex].
• Parameter 1 - Filter interface pointer. Use 'ln poi(<value>)' to find the filter.
• Parameter 2 - Not used.
• Parameter 3 - Not used.
• Parameter 4 - Not used.

Additional Information

• Test Layer: PrintDriver

Print driver has mismatch of AddRef/Release calls of PT/PC XML Document.

Probable cause

This verifier stop occurs when a print driver incorrectly manages the reference count of an XML Document (eg, PrintTicket or PrintCapabilities). The reference count was not expected to be changed by the method call and will likely lead to a leak and/or an orphaned critical section in the XML DOC.

Information displayed by Application Verifier

• Format: -  After %lS method call, %lS XML Document ref count is %d, expected %d.
• Parameter 1 - Name of offending method call. If not NULL, Use 'du' to display this.
• Parameter 2 - Type of XML Document. If not NULL, Use 'du' to display this.
• Parameter 3 - Current reference count.
• Parameter 4 - Expected reference count.

FatalExit was called

Probable cause

FatalExit was called. This is a form of abnormal termination which may cause other verifier stops to be reported (eg. leaks), but for which no corrective action is possible (ie, the stops are unreliable and noisy). To troubleshoot this stop: Dump the current stack trace by using the 'k' command in the debugger to identify the module and routine that invoked FatalExit.

Information displayed by Application Verifier

• Parameter 1 - Exit code.
• Parameter 2 - Not used.
• Parameter 3 - Not used.
• Parameter 4 - Not used.
