lib/libc using a reach-over makefile.
A typical use-case is to build a standard ILP32 version and a COMPAT32
version in a single iteration by building the COMPAT32 version using a
reach-over makefile.

it is all in the one place again. Rename libc/iconv/iconv.c to
bsd_iconv.c. Compile the wrappers into libc.a so that WITHOUT_DYNAMICROOT
works again.
Discussed with: kib (and partly stolen from his patch)
when there is an invalid character in the output codeset while it is
valid in the input. However, POSIX requires iconv() to perform an
implementation-defined conversion on the character. So, Citrus iconv converts
such a character to a special character which means it is invalid in the
output codeset.
This is not a problem in most cases but some software like libxml2 depends
on GNU's behavior to determine if a character is output as-is or another form
such as a character entity (&#NNN;).
FreeBSD systems usually implemented this as a third party module and
our implementation hasn't played as nicely with the old way as it could
have.
To that end:
* Rename the iconv* symbols in libc.so.7 to have a __bsd_ prefix.
* Provide .symver compatability with existing 10.x+ binaries that
referenced the iconv symbols. All existing binaries should work.
* Like on Linux/glibc systems, add a libc_nonshared.a to the ldscript
at /usr/lib/libc.so.
* Move the "iconv*" wrapper symbols to libc_nonshared.a
This should solve the runtime ambiguity about which symbols resolve
to where. If you compile against the iconv in libc, your runtime
dependencies will be unambiguous.
Old 9.x libraries and binaries will always resolve against their
libiconv.so.3 like they did on 9.x. They won't resolve against libc.
Old 10.x binaries will be satisified by the .symver helpers.
This should allow ports to selectively compile against the libiconv
port if needed and it should behave without ambiguity now.
Discussed with: kib
good. This caused libc to spoof the ports libiconv namespace and
provide a colliding libiconv.so.3 to fool rtld. This should have
been removed some time ago.
_citrus_mapper_close again and result in a deadlock otherwise.
This is similar to NetBSD PR/24023 (fixed in their r1.5 of this file).

extensions and also tried to be link time compatible with ports libiconv.
This splits that functionality and enables the parts that shouldn't
interfere with the port by default.
WITH_ICONV (now on by default) - adds iconv.h, iconv_open(3) etc.
WITH_LIBICONV_COMPAT (off by default) adds the libiconv_open etc API, linker
symbols and even a stub libiconv.so.3 that are good enough to be able
to 'pkg delete -f libiconv' on a running system and reasonably expect it
to work.
I have tortured many machines over the last few days to try and reduce
the possibilities of foot-shooting as much as I can. I've successfully
recompiled to enable and disable the libiconv_compat modes, ports that use
libiconv alongside system iconv etc. If you don't enable the
WITH_LIBICONV_COMPAT switch, they don't share symbol space.
This is an extension of behavior on other system. iconv(3) is a standard
libc interface and libiconv port expects to be able to run alongside it on
systems that have it.
Bumped osreldate.
bypass mode when src == dst. Unfortunately, there are tools in ports
that pass byte streams through iconv to determine if the encodings
are valid. eg: gettext-0.18.3+.
Disable the optimization and behave like the other implementations.
a macro with parameters. Remove a __DECONST hack and add consts instead
for gnu libiconv API compatability. This makes it work with things like
devel/boost-libs that expects to use "iconv" as though it were a pointer.
Expose iconv functions as weak symbols as well as their internal
remapped #define names. This is necessary for autoconf compatability -
on Linux it appears that #include <iconv.h> isn't a link time
prerequisite for their version that's built into glibc.
Initialize the pthread rwlock. Note that upstream has three
separate locks. The file-local static lock appears intentional.
I'm using this as a ports-compatible compile-time substitute for
converters/libiconv on one of my personal machines.
- Remove an unneeded variable.
- Fix whitespace bugs.
- Fix typoes in comment.
- Improve string handling a bit. Don't handroll strstr() and don't
terminate a strdup()'ed string. Instead, simply strndup() the part we
need.
If we were already provided a struct _citrus_iconv (e.g. through
iconv_open_into()), we should not call free() in case io_init_context()
fails. Instead, call it on the pointer of the allocated object, which
will be NULL in case of iconv_open_into().
A fork/exec could happen between open and fcntl, leaking a file descriptor.
Using O_CLOEXEC fixes this and as a side effect simplifies the code.
NetBSD already had this (I checked this after making the change myself).

setting. It can be built by setting the WITH_ICONV knob. While this
knob is unset, the library part, the binaries, the header file and
the metadata files will not be built or installed so it makes no impact
on the system if left turned off.
This work is based on the iconv implementation in NetBSD but a great
number of improvements and feature additions have been included:
- Some utilities have been added. There is a conversion table generator,
which can compare conversion tables to reference data generated by
GNU libiconv. This helps ensuring conversion compatibility.
- UTF-16 surrogate support and some endianness issues have been fixed.
- The rather chaotic Makefiles to build metadata have been refactored
and cleaned up, now it is easy to read and it is also easier to add
support for new encodings.
- A bunch of new encodings and encoding aliases have been added.
- Support for 1->2, 1->3 and 1->4 mappings, which is needed for
transliterating with flying accents as GNU does, like "u.
- Lots of warnings have been fixed, the major part of the code is
now WARNS=6 clean.
- New section 1 and section 5 manual pages have been added.
- Some GNU-specific calls have been implemented:
iconvlist(), iconvctl(), iconv_canonicalize(), iconv_open_into()
- Support for GNU's //IGNORE suffix has been added.
- The "-" argument for stdin is now recognized in iconv(1) as per POSIX.
- The Big5 conversion module has been fixed.
- The iconv.h header files is supposed to be compatible with the
GNU version, i.e. sources should build with base iconv.h and
GNU libiconv. It also includes a macro magic to deal with the
char ** and const char ** incompatibility.
- GNU compatibility: "" or "char" means the current local
encoding in use
- Various cleanups and style(9) fixes.
