=head2 Internals
|
|
|
|
Git hosting has moved to http://github.com/libguestfs
|
|
|
|
The various test directories have been rearranged logically, and now
|
|
all appear under 'tests/'.
|
|
|
|
There is a 'make extra-tests' rule which runs ordinary tests and
|
|
additional tests, using valgrind to check for memory problems.
|
|
|
|
Multiple memory leaks and other problems found by valgrind and fixed.
|
|
|
|
Support for optional arguments in the generator has been rewritten
|
|
to provide more features and safety (Matthew Booth).
|
|
|
|
With gcc -fvisibility=hidden is used for internal symbols, avoiding
|
|
call indirection via the PLT.
|
|
|
|
RHashtable functions can be tested in the generator.
|
|
|
|
ADD_ARG macro in daemon allows arg lists to be constructed without
|
|
risk of stack smashing.
|
|
|
|
Fix generation of OCaml functions that have more than 10 arguments.
|
|
|
|
psmisc has been added to the appliance, allowing use of 'fuser',
|
|
'killall' and 'pstree' for debugging.
|
|
|
|
bindtests now cover RBufferOut and optional arguments (Matthew Booth).
