Earlier lint cleanups overlooked a couple of modules because on macOS at
the moment oclint ignores them. I noticed this when I ran `make lint-all`
on Ubuntu.
This only eliminates errors reported by `make lint`. It shouldn't cause any
functional changes.
This change does remove several functions that are unused. It also removes the
`desc_arr` variable which is both unused and out of date with reality.
I noticed that the `test_convert()` function was randomly failing when
run on OS X Snow Leopard. I tracked it down to the `mbrtowc()` function on
that OS being broken. Explicitly testing for UTF-8 prefixes that identify
a sequence longer than four bytes (which the Unicode standard made illegal
long ago) keeps us from having encoding errors on those OS's.
This also makes the errors reported by the `test_convert()` function actually
useful and readable.
Lastly, it makes it possible to build fish on OS X Snow Leopard.
Drops configure check for wcsdup, wcslen, wcscasecmp, wcsncasecmp,
wcwidth, wcswidth, wcstok, fputwc, fgetwc, and wcstol. Drop the fallback
implementations of these on non-Snow Leopard platforms.
Work on #2999.
fwprintf would segfault on DragonFly BSD 1.4.0, released in January
2006. This was fixed by DragonFly BSD 1.4.4, released in April 2006. It
seems unlikely that anyone is still running a ten-year-old, unsupported
version, and hoping that fish will continue to build.
I've checked this in virtual machines.
Work on #2999.
Reduces lint errors from 36 to 33 (-8%). Line count from 1910 to 1476 (-23%).
Another step in resolving issue #2902.
This also fixes a stupid mistake from an earlier commit where I didn't realize
that osx/config.h was meant to be included as a semi-static file in the
repository.
Remove the "make iwyu" build target. Move the functionality into the
recently introduced lint.fish script. Fix a lot, but not all, of the
include-what-you-use errors. Specifically, it fixes all of the IWYU errors
on my OS X server but only removes some of them on my Ubuntu 14.04 server.
Fixes#2957
The relevant standards allow the mbtowc/mbrtowc functions to reject
non-ASCII characters (i.e., chars with the high bit set) when the locale
is C or POSIX. The BSD libraries (e.g., on OS X) don't do this but
the GNU libraries (e.g., on Linux) do. Like most programs we need the
C/POSIX locales to allow arbitrary bytes. So explicitly check if we're
in a single-byte locale (which would also include ISO-8859 variants)
and simply pass-thru the chars without encoding or decoding.
Fixes#2802.
There is no longer a good reason to detect whether or not getopt_long()
is available. All UNIX implementations we're likely to run on have it. And
if we ever find one that doesn't the right thing to do is not fallback to
getopt() but to include the getopt_long() source in our package like we
do with the pcre2 library. Since it's licensed under LGPL we can legally
do so if it becomes necessary.
This partially addresses issue #2790.
This change moves source files into a src/ directory,
and puts object files into an obj/ directory. The Makefile
and xcode project are updated accordingly.
Fixes#1866
