Implement out-of-process dump generation for Windows platform.
Details:
- Created a lib, crash_generation.lib, that implements the out-of-process dump generation protocol.
- The lib code is under client/windows/crash_generation folder and is organized in the following way:
- CrashGenerationServer class (crash_generation_server.h/.cc) implements the server side of
the protocol.
- CrashGenerationClient class (crash_generation_client.h/.cc) implements the client side of
the protocol.
- MinidumpGenerator class (minidump_generator.h/.cc) serves as an abstractino for generating
dump files using Windows APIs, coming up with new file names by creating GUIDs, etc.
- ProtocolMessage class (ipc_protocol.h) represents the message format between the client and server
for pipe IPC.
- Server allows one client at a time on the pipe in the current implementation.
- ReadMe.txt explains the state machine the server uses to serve clients.
- ExceptionHandler is modified and a new constructor is added that allows specifying the pipe name. If the
pipe name is NULL, the behavior is backward compatible - in-process dump generation is done as before. If
the pipe name is specified, out-of-process dump generation registration is attempted. If that fails, the
behavior is again backward compatible.
- If out-of-process registration succeeds, all write dump requests, direct or indirect, are directed to
crash server process that served the registration request. NOTE that the explicit dump requests made by
calling the static method of ExceptionHandler are not directed to theserver.
- client/windows/tests/crash_generation_app implements a simple Win32 GUI application to help test the
out-of-process dump generation client and server. Typical use of the app is to start one instance, click
Server --> Start and then start the other instance. The other instance will register with the first
instance automatically at start-up. Then the second instance can be used to request various typoes of
dump requests by using options under the Client menu.
