Check /sbin, /usr/sbin, /bin and /usr/bin to ensure that neither the
directory nor the parent (eg. /usr) is a symlink, and use this
directory for the virtual directory used to store guestfsd in the
appliance.
This file shouldn't be included in the tarball as it contains
hard-coded paths from the maintainer's machine which cannot be
relevant to the target machine.
Callers are supposed to use the availability API to check for
functions that may not be available in particular builds of
libguestfs. If they don't do this, currently they tend to get obscure
error messages, eg:
libguestfs: error: zerofree: /dev/vda1: zerofree: No such file or directory
This commit changes the error message to explain what callers ought to
be doing instead:
libguestfs: error: zerofree: feature 'zerofree' is not available in this
build of libguestfs. Read 'AVAILABILITY' in the guestfs(3) man page for
how to check for the availability of features.
This patch makes the stubs check for availability. The stub code
changes to:
static void
zerofree_stub (XDR *xdr_in)
{
[...]
/* The caller should have checked before calling this. */
if (! optgroup_zerofree_available ()) {
reply_with_error ("feature '%s' is not available in this\n"
"build of libguestfs. Read 'AVAILABILITY' in the guestfs(3) man page for\n"
"how to check for the availability of features.",
"zerofree");
goto done;
}
[...]
Set LD_LIBRARY_PATH so we link against the just-built library, not
the installed library.
Use OCAMLCFLAGS instead of OCAMLOPTFLAGS where appropriate.
Remove unnecessary -cclib option for bytecode linking (gcc is not used
in this case).
This fixes commit eb68a31413.
The error messages would be prefixed by the path to the
alternate binary, eg:
../fish/guestfish: invalid escape sequence in string (starting at offset 0)
Fix this by normalizing the messages further.
RConstOptString cannot return an error in the C api. This makes it a special
case for the GObject api, as all other return types have a corresponding GError
**err argument to return an error. This change removes this special case, and
includes the possibility of an error return in the API. An error is indicated by
setting *err to a non-NULL value.
This change is in preparation for adding a close api. An attempt to call any
api, even RConstOptString, on a closed handle must return an error.
Change 'ifconfig' and 'netstat' commands to use 'ip' instead.
'iproute' was already included in the appliance, so this reduces the
size of the appliance accordingly.
This commit tidies up the code by splitting out the path
element-searching code into a separate function.
Valgrind found that 'closedir' frees the 'struct dirent *', which
wasn't immediately obvious. So now we do the 'closedir' after all
operations which touch 'd->d_name'.
