Since the daemon links to pcre and use regular expressions, and since the COMPILE_REGEXP macro doesn't depend on any aspects of the library-side code (eg. the guestfs_h handle etc), we can allow the daemon to use the COMPILE_REGEXP macro. Move the macro to "guestfs-internal-all.h" to permit this. --- src/guestfs-internal-all.h | 26 ++++++++++++++++++++++++++ src/guestfs-internal.h

Currently we are unable to properly run guestfsd (the daemon) under valgrind. Attempts to run valgrind inside the appliance have not been successful (see patch 1/7). However we desperately need better valgrind coverage of the daemon, particularly because it is doing a lot of complex parsing of program output. This has been a problem for a long time. A better way to attack this problem is to

This is a simpler patch that removes GUESTFSD_EXT_CMD completely.

Replace GUESTFSD_EXT_CMD with a command line option ‘./guestfsd --print-external-commands’
