99 Internals
101 Git hosting has moved to http://github.com/libguestfs
102 The various test directories have been rearranged logically, and now
104 all appear under 'tests/'.
105 There is a 'make extra-tests' rule which runs ordinary tests and
107 additional tests, using valgrind to check for memory problems.
108 Multiple memory leaks and other problems found by valgrind and fixed.
110 Support for optional arguments in the generator has been rewritten
112 to provide more features and safety (Matthew Booth).
113 With gcc -fvisibility=hidden is used for internal symbols, avoiding
115 call indirection via the PLT.
116 RHashtable functions can be tested in the generator.
118 ADD_ARG macro in daemon allows arg lists to be constructed without
120 risk of stack smashing.
121 Fix generation of OCaml functions that have more than 10 arguments.
123 psmisc has been added to the appliance, allowing use of 'fuser',
125 'killall' and 'pstree' for debugging.
126 bindtests now cover RBufferOut and optional arguments (Matthew Booth).
