3 * Existing services can now be managed using the GUI
\r
4 or on the command line.
\r
6 * NSSM can now set the priority class and processor
\r
7 affinity of the managed application.
\r
9 * NSSM can now apply an unconditional delay before
\r
10 restarting the application.
\r
12 * NSSM can now optionally rotate existing files when
\r
15 * Unqualified path names are now relative to the
\r
16 application startup directory when redirecting I/O.
\r
18 * NSSM can now set the service display name, description,
\r
19 startup type and log on details.
\r
21 * All services now receive a standard console window,
\r
22 allowing them to read input correctly (if running in
\r
27 * Services installed from the GUI no longer have incorrect
\r
28 AppParameters set in the registry.
\r
32 * Services installed from the commandline without using the
\r
33 GUI no longer have incorrect AppStopMethod* registry
\r
38 * Support AppEnvironmentExtra to append to the environment
\r
39 instead of replacing it.
\r
41 * The GUI is significantly less sucky.
\r
45 * Timeouts for each shutdown method can be configured in
\r
48 * The GUI is slightly less sucky.
\r
52 * NSSM can now redirect the service's I/O streams to any path
\r
53 capable of being opened by CreateFile().
\r
55 * Allow building on Visual Studio Express.
\r
57 * Silently ignore INTERROGATE control.
\r
59 * Try to send Control-C events to console applications when
\r
64 * Fixed case where NSSM could kill unrelated processes when
\r
69 * NSSM is now translated into Italian.
\r
71 * Fixed GUI not allowing paths longer than 256 characters.
\r
75 * Fixed default GUI language being French not English.
\r
79 * Fixed failure to run on Windows 2000.
\r
83 * NSSM is now translated into French.
\r
85 * Really ensure systems recovery actions can happen.
\r
87 The change supposedly introduced in v2.4 to allow service recovery
\r
88 actions to be activated when the application exits gracefully with
\r
89 a non-zero error code didn't actually work.
\r
93 * Support AppEnvironment for compatibility with srvany.
\r
97 * Fixed failure to compile messages.mc in paths containing spaces.
\r
99 * Fixed edge case with CreateProcess().
\r
101 Correctly handle the case where the application executable is under
\r
102 a path which contains space and an executable sharing the initial
\r
103 part of that path (up to a space) exists.
\r
107 * Fixed failure to run on Windows versions prior to Vista.
\r
111 * Read Application, AppDirectory and AppParameters before each restart so
\r
112 a change to any one doesn't require restarting NSSM itself.
\r
114 * Fixed messages not being sent to the event log correctly in some
\r
117 * Try to handle (strictly incorrect) quotes in AppDirectory.
\r
119 Windows directories aren't allowed to contain quotes so CreateProcess()
\r
120 will fail if the AppDirectory is quoted. Note that it succeeds even if
\r
121 Application itself is quoted as the application plus parameters are
\r
122 interpreted as a command line.
\r
124 * Fixed failed to write full arguments to AppParameters when
\r
125 installing a service.
\r
127 * Throttle restarts.
\r
129 Back off from restarting the application immediately if it starts
\r
130 successfully but exits too soon. The default value of "too soon" is
\r
131 1500 milliseconds. This can be configured by adding a DWORD value
\r
132 AppThrottle to the registry.
\r
134 Handle resume messages from the service console to restart the
\r
135 application immediately even if it is throttled.
\r
137 * Try to kill the process tree gracefully.
\r
139 Before calling TerminateProcess() on all processes assocatiated with
\r
140 the monitored application, enumerate all windows and threads and
\r
141 post appropriate messages to them. If the application bothers to
\r
142 listen for such messages it has a chance to shut itself down gracefully.
\r
146 * Handle missing registry values.
\r
148 Warn if AppParameters is missing. Warn if AppDirectory is missing or
\r
149 unset and choose a fallback directory.
\r
150 First try to find the parent directory of the application. If that
\r
151 fails, eg because the application path is just "notepad" or something,
\r
152 start in the Windows directory.
\r
154 * Kill process tree when stopping service.
\r
156 Ensure that all child processes of the monitored application are
\r
157 killed when the service stops by recursing through all running
\r
158 processes and terminating those whose parent is the application
\r
159 or one of its descendents.
\r
163 * Removed incorrect ExpandEnvironmentStrings() error.
\r
165 A log_event() call was inadvertently left in the code causing an error
\r
166 to be set to the eventlog saying that ExpandEnvironmentStrings() had
\r
167 failed when it had actually succeeded.
\r
171 * Allow use of REG_EXPAND_SZ values in the registry.
\r
173 * Don't suicide on exit status 0 by default.
\r
175 Suiciding when the application exits 0 will cause recovery actions to be
\r
176 taken. Usually this is inappropriate. Only suicide if there is an
\r
177 explicit AppExit value for 0 in the registry.
\r
179 Technically such behaviour could be abused to do something like run a
\r
180 script after successful completion of a service but in most cases a
\r
181 suicide is undesirable when no actual failure occurred.
\r
183 * Don't hang if startup parameters couldn't be determined.
\r
184 Instead, signal that the service entered the STOPPED state.
\r
185 Set START_PENDING state prior to actual startup.
\r
189 * Ensure systems recovery actions can happen.
\r
191 In Windows versions earlier than Vista the service manager would only
\r
192 consider a service failed (and hence eligible for recovery action) if
\r
193 the service exited without setting its state to SERVICE_STOPPED, even if
\r
194 it signalled an error exit code.
\r
195 In Vista and later the service manager can be configured to treat a
\r
196 graceful shutdown with error code as a failure but this is not the
\r
199 Try to configure the service manager to use the new behaviour when
\r
200 starting the service so users who set AppExit to Exit can use recovery
\r
201 actions as expected.
\r
203 Also recognise the new AppExit option Suicide for use on pre-Vista
\r
204 systems. When AppExit is Suicide don't stop the service but exit
\r
205 inelegantly, which should be seen as a failure.
\r
209 * Send properly formatted messages to the event log.
\r
211 * Fixed truncation of very long path lengths in the registry.
\r
215 * Decide how to handle application exit.
\r
217 When the service exits with exit code n look in
\r
218 HKLM\SYSTEM\CurrentControlSet\Services\<service>\Parameters\AppExit\<n>,
\r
219 falling back to the unnamed value if no such code is listed. Parse the
\r
220 (string) value of this entry as follows:
\r
222 Restart: Start the application again (NSSM default).
\r
223 Ignore: Do nothing (srvany default).
\r
224 Exit: Stop the service.
\r
228 * Added support for building a 64-bit executable.
\r
230 * Added project files for newer versions of Visual Studio.
