Only in end-user messages and documentation. This change was done
mostly mechanically using the Perl script attached below.
I also changed don't -> don’t etc and made some other simple fixes.

Run the following command over the source:
perl -pi.bak -e 's/(20[01][0-9])-2016/$1-2017/g' `git ls-files`
(Thanks Rich for the perl snippet, as used in past years.)
Like with the previous commit, this replaces instances of:
if (something_bad) {
fprintf (stderr, "%s: error message\n", guestfs_int_program_name);
exit (EXIT_FAILURE);
}
with:
if (something_bad)
error (EXIT_FAILURE, 0, "error message");
(except in a few cases were errno was incorrectly being ignored, in
which case I have fixed that).
It's slightly more complex than the previous commit because we must be
careful to:
- Remove the program name (since error(3) prints it).
- Remove any trailing \n character from the message.
Candidates for replacement were found using:
pcregrep --buffer-size 10M -M '\bfprintf\b.*\n.*\bexit\b' `git ls-files`
Wherever we had code which did:
if (something_bad) {
perror (...);
exit (EXIT_FAILURE);
}
replace this with use of the error(3) function:
if (something_bad)
error (EXIT_FAILURE, errno, ...);
The error(3) function is supplied by glibc, or by gnulib on platforms
which don't have it, and is much more flexible than perror(3). Since
we already use error(3), there seems to be no downside to mandating it
everywhere.
Note there is one nasty catch with error(3): error (EXIT_SUCCESS, ...)
does *not* exit! This is also the reason why error(3) cannot be
marked as __attribute__((noreturn)).
Because the examples can't use gnulib, I did not change them.
To search for multiline patterns of the above form, pcregrep -M turns
out to be very useful:
pcregrep --buffer-size 10M -M '\bperror\b.*\n.*\bexit\b' `git ls-files`
Not to be confused with the libxml2 macro 'BAD_CAST' which converts
from 'signed char *' to 'unsigned char *'.
The 'bad_cast' function was defined and used all over the place as a
replacement for a '(char *)' cast. I think it is better to make these
casts explicit, instead of hiding them in an obscure function.
gettextize provides a local file called "gettext.h". Remove this and
use <libintl.h> from glibc headers instead.
Most of this change is mechanical: #include <libintl.h> in every C
file which uses any gettext function. But also we remove the
gettext.h file, and adjust the "_" macros.
Note that this effectively removes the ./configure --disable-nls
option, although we don't know if that ever worked.
In guestfish, factor out the processing of the options -a, -c,
-d, -i, -m, -n, -r, -v, -V, -x into a separate set of files:
options.c, options.h, inspect.c, virt.c.
Change guestmount so that it uses these same files (from the
../fish directory) to process the same options.
This unifies the handling of these options between the two programs.
It also adds the useful inspection feature to guestmount, so you
can now do:
guestmount -d Guest -i --ro mnt/
Previously the list of -a, -d, -m, -N parameters were leaked. This
change frees them explicitly.
This is not such an important fix since guestfish is a one-shot
program, but it aids in finding other leaks in future.
(Found by valgrind).
Previously you might have typed:
$ guestfish
><fs> alloc test1.img 100M
><fs> run
><fs> part-disk /dev/sda mbr
><fs> mkfs ext4 /dev/sda1
now you can do the same with:
$ guestfish -N fs:ext4
Some tests have also been updated to use this new
functionality.
