shutdown command. START, STOP, RESTART, CONNECT 27 Integration in the operating system: the Service Wrapper In the previous chapter, we saw the different scripts and commands to start, stop, restart Apache provides the "Service Wrapper". The service wrapper allows you to directly integrate Apache Karaf: • like a native Windows Service • like a Unix daemon process The "Service Wrapper" correctly handles It also includes advanced fault detection software which monitors an application. The "Service Wrapper" is able to detect crashes, freezes, out of memory and other exception events, then automatically

Class-aware C++ API C++ wrapper classes wrap most fz_* and pdf_* C structs. • Class names are camel-case versions of the wrapped struct’s name, for example fz_document’s wrapper class is mupdf::FzDocument be treated as values and copied arbitrarily. Class-aware functions and methods take and return wrapper class instances instead of MuPDF C structs. • No fz_context* arguments. • MuPDF exceptions are the corresponding wrapper class. 141 MuPDF Documentation, Release 1.21.2 • Where a MuPDF function returns a pointer to a struct, the class-aware C++ wrapper will return a wrapper class instance by value

Design Differences from zope.server waitress API Arguments to waitress.serve Support for wsgi.file_wrapper waitress-serve Glossary Change History 1.1.0 (2017-10-10) Features Waitress now has a __main__ com/nose-devs/nose/issues/407 for more information. Give the WSGI app_iter generated when wsgi.file_wrapper is used (ReadOnlyFileBasedBuffer) a close method. Do not call close on an instance of such a class of extremely large output buffers (greater than 2GB, suspected to be buffers added via wsgi.file_wrapper) might cause an OverflowError on Python 2.
