0.33:
add byte_start, byte_starts
add a man page for byte_equal_notimingattack
buffer_seek is no longer limited to the current buffer contents
add automated way to run unit test: make check
add parse.h
add bytestream abstraction for parsing data from a buffer or a file
add compiler.h to abstract gcc attributes
add fmt_strm_malloc
add cross references to open_* and mmap_* man pages
add fmt_strm_alloca and fmt_strm_malloc man pages
add buffer_init_allocbuf, buffer_init_read, buffer_init_write, buffer_init_read_allocbuf, buffer_init_write_allocbuf
fix buffer overread for len=0 in scan_longn (Martin Castillo)
0.32:
remove OpenBSD #warning (obsd maintainer says no longer needed)
move headers to <libowfat/> upon install
fix fmt_ip6 (Erwin Hoffmann)
add MSG_ZEROCOPY support (only used for buffers >8k)
use writev in buffer_put for a slight perf improvement
add experimental iom API for multithreaded I/O multiplexing (in io.h)
0.31:
special case buffer_get_token with token length 1 through memccpy (almost 4x speedup)
test for pread and use it instead of lseek+read in cdb and io_mmapwritefile
add mmap_readat (like mmap_read but open by fd, not by name)
add fmt_iso8601 and scan_iso8601 (time_t -> "2014-05-27T19:22:16Z")
add fmt_netstring and scan_netstring (http://cr.yp.to/proto/netstrings.txt)
add (fmt|scan)_varint and (fmt|scan)_pb_* (binary marshaling ala protocol buffers)
0.30:
add compiletimeassert.h
add haveuint128.h
byte.h now defines UNALIGNED_ACCESS_OK on x86
add scan_ulongn, scan_8longn, scan_xlongn, scan_longn, scan_netstring
change buffer to have a destructor function pointer
SECURITY: fmt_strn would write one byte too many (returned right length though, so usually not a problem as that byte would be overwritten with \0 by the caller anyway)
fmt_pad and fmt_fill fail more gracefully when srclen > maxlen
You can now say $ make WERROR=-Werror (compiling t.c may fail but that's strictly speaking not part of the library)
scan_html now decodes HTML entities based on the actual w3c list (from entities.json, say gmake update to fetch the current version)
added fmt_escapechar* to fmt.h (implement various escaping mechanisms also found in textcode but for a single char not a whole string, and they always escape, not just when they think it's needed)
scan_ushort was supposed to abort early and return 5 when attempting to parse "65536", because the result does not fit. It did not. Now it does.
scan_*long, scan_*int, scan_*short now properly abort if the number would not fit
SECURITY: check for integer overflow in stralloc_ready
switch io_fds from array to newly implemented (hopefully thread-safe) iarray
switch epoll from level triggering to edge triggering
introduce io_eagain_read and io_eagain_write (discontinue using io_eagain plz)
fix buffer_get
add fmt_html_tagarg, fmt_xml, scan_html_tagarg
add socket_fastopen, socket_fastopen_connect4, socket_fastopen_connect6 and socket_quickack
on Linux, in iob_send, if MSG_MORE is defined, and the request type
lends itself to it, used sendto/sendmsg with MSG_MORE instead of
TCP_CORK (saves two syscalls)
add io_fd_flags so the caller can tell io_fd whether the socket is blocking
(saves one fcntl syscall)
more constness for stralloc and buffer
mmap_read/mmap_shared on zero length files no longer fail but return a
zero length buffer
if SOCK_NONBLOCK is defined, use it instead of socket+fcntl
... but if errno==EINVAL still fall back to socket+fcntl (Robert Henney)
SECURITY: fix botched integer overflow handling logic in stralloc_ready (Giorgio)
add critbit
0.29:
save 8 bytes in taia.h for 64-bit systems
add buffer_tosa (buffer writing to auto-growing stralloc)
add iarray
support SCTP in addition to TCP
fix io_receivefd so the incoming buffer is only 1 byte; io_passfd
sends only one byte, so we might receive (and discard) other data if
we try to read more (Stefan Bühler, from the lightttpd project)
add io_fd_canwrite (like io_fd but assume the fd is writable)
save a few syscalls here and there
add awesome hack in isset.h (comex, Linus Torvalds)
add byte_equal_notimingattack
0.28:
add uint64 pack and unpack routines
fix subtle typo in sub_of (David Sirovsky)
work around gcc bugs
0.27:
add fmt_strm
add iob_addbuf_munmap
add socket_deferaccept
catch one more case in umult64 (Tomi Jylhä-Ollila)
0.26:
fix really pathological case where io_timeouted would never
start over from the beginning because always new accept()ed
connections came in and got newer, higher descriptors since the last
io_timeouted loop. (Dirk Engling)
add some int overflow check macros to rangecheck.h
fmt_ip6 compresses at best spot, not at first spot (Nikola Vladov)
use inttypes.h to declare ints in uint*.h
escape more in fmt_ldapescape
try to catch malicious input in textcode fmt_* functions
fmt_xlonglong was utterly broken (Johannes Vetter)
0.25:
array_allocate no longer truncates the array
array_get now not only checks whether the element fits in the
allocates space, it also needs to be in the initialized space.
add -D_REENTRANT to CFLAGS so libowfat can be used in multi-threaded
programs
further Windoze support (test/io5.c works, gatling still doesn't)
This is just to get gatling to work, I may remove it again after
that.
implement Nikola's idea to remove limit number of strings in errmsg
add taia_half
add cdb
add rangecheck.h
add io_block
make socket_(tc|ud)p[46] actually return non-blocking sockets as
documented (Richard Lyons)
fix for NetBSD 3.0 (Their /sys/types.h actually does not define u_char
unless you #define _NETBSD_SOURCE, and then their CMSG_* macros use
it. This is horrible even by OpenBSD standards)
remove support for ip6.int (it's no longer delegated)
add asm versions of imult64 and umult64 for x86_64
(22 cycles -> 12 cycles on my Athlon 64)
use size_t and ssize_t instead of unsigned long et al
add iob_bytesleft
don't leak memory in test/httpd
0.24:
fix scan_to_sa (Tim Lorenz)
turns out we can not do file descriptor passing on OpenBSD
if _XOPEN_SOURCE is defined, which is needed for Solaris.
OpenBSD sucks. I checked in a _really_ kludge now. Please do not
use OpenBSD if you have a choice. Or Solaris, for that matter.
turns out the imult routines (which I never used) were incorrect.
Noted by Matthew Dempsky
open_* from open.h now open in large file mode
0.23:
also recognize EPFNOSUPPORT as EAFNOSUPPORT (groan)
fix a few man pages
optimize fmt_base64 (Dan Gundlach)
gcc 4 cleanups (mostly unsigned char* vs char*)
fix scan_xlong, scan_xlonglong and scan_8long
remove a few gcc 4 warnings
work around freebsd 5.4 brokenness (if you don't have IPv6 in the
kernel, socket(PF_INET6,SOCK_STREAM,0) returns EPROTONOSUPPORT
instead of EPFNOSUPPORT, which basically says "yeah, I know IPv6,
but TCP? never heard of it")
remove even more warnings
64-bit cleanliness issue with auto-NULL-appending macros
IRIX compatibility (yuck!)
0.22:
uh, the scope_id detection #defined the wrong constant. libowfat
always thought there was no scope_id. Oops.
#include <unistd.h> in io/io_sendfile.c (broken OpenBSD, thx Rob)
add scan_urlencoded2 (like scan_urlencoded but will not convert '+' to
' '; needed for web servers, so they can serve libstdc++.tar.gz)
fix iob_write to handle failure properly
document that the iob_write callback should limit itself
fix mmap_shared
add iob_free, add man pages for iob_free and iob_reset
fix descriptor leak in iob_addfile_close if the range was 0 (oops)

errno cleanup and man page updates (Rolf Eike Beer)
implement iob_prefetch with madvise MADV_WILLNEED if it's defined
extend API To read line/token to stralloc to allow clearing the
stralloc first.
add stralloc_zero to clear a stralloc
add buffer_putsflush
add stralloc_catm and stralloc_copym
add buffer_putm and buffer_putmflush
cleanups in stralloc and buffer:
int -> long for sizes
char -> unsigned char for strings
buffer_getline is now a function, not a macro
add iob_write (send io batch through callback, e.g. for SSL)
add errmsg_info and errmsg_infosys to write to stdout instead
epoll fix (how could this ever work?)
0.20:
add errmsg API
work around broken Linux sendfile API (offset 64-bit but count 32-bit)
add io_appendfile, io_readwritefile
support ip6.arpa in addition to ip6.int in dns_name (adds one
parameter to dns_name6_domain and two constants in dns.h)
Solaris compatibility for io_passfd and io_receivefd
0.19.2:
for some reason, a botched dependency slipped in the the Makefile
0.19.1:
oops, I botched havealloca.h, which was not generated but static
Now it is generated.
0.19:
add io_socketpair
add io_passfd and io_receivefd (and test/fdpassing.c)
io_trywrite and io_waitwrite not ignore SIGPIPE
add man pages for libio, safemult
fix possible signal race in io_tryread and io_trywrite (Scott Lamb)
fix byte_rchr return value (Marcus Winkler)

sent me a patch :-D)
add iob_addfile_close, needed for gatling 0.5+
add test/client and test/server, two simple TCP shell interfaces
0.17:
add Linux SIGIO support to IO
expand IO api to be able to cope with edge triggered event
notification: introduce io_eagain
the integer scan routines should only write *dest if they actually
scanned something
io_sendfile and iob_send should return -1 to -3 just like io_trywrite
make io_waituntil actually take an "until", not a "how long"
turns out that BSD kqueue is actually Free/OpenBSD kqueue -- NetBSD
doesn't have it. That means I'll need some adaptive two-threads-
running-poll approach to get C10k type scalability on NetBSD :-(
turns out that BSD sendfile is actually FreeBSD sendfile -- neither
OpenBSD nor NetBSD have it (as of 3.4 and 1.6.1). That means I'll
need to try using mmap on OpenBSD and NetBSD to get zero-copy TCP.
guard against same event being signalled twice (confused our list
handling)
add support for Solaris /dev/poll
add lose32 support (broken, please don't use!)
head -1 -> head -n 1
apending 0 bytes to an empty array would fail it
remove socket_sendfile now that we have io_sendfile
break out alloca #include dependency into havealloca.h
support HP-UX sendfile64 (thanks to Rolf Eike Beer)
support Solaris sendfile64
support MacOS X sendfile (and comment it out again, the headers
declare it but it's not actually there) (thanks to Bernhard Schmidt)
support AIX 5 (thanks to Lutz Chwala and Arthur Erhardt)

add API for integer multiply with overflow detection
change length counters from int to long for 64-bit platforms
add array API from http://cr.yp.to/lib/array.html
oops, had a declaration and man page for taia_addsec but not the
function itself
add buffer functions to write strerror(errno)
add io API supporting poll, epoll and kqueue
remove obsolete "extern" from header files
add iob API to send several buffers and files in one batch

man page update (document stralloc return values)
add stralloc_chop and stralloc_chomp
add buffer_putsa, buffer_get_token_sa and buffer_getline_sa
extended uudecode test. See comment at top for details.
fix #include in ndelay*.3 (Hynek Schlawack)
add stralloc_diff and stralloc_diffs (my invention)
scan_ip6 returned 1 for "::" (Uwe Ohse)
add el-cheapo MIME decoding to test/uudecode
make install forgot to install ndelay.h
fix typos in several man pages (Hynek Schlawack)

fmt_strn did not work for out==NULL
fix inconsistencies in man pages
make scan_urlencode do the '+' -> ' ' transformation
0.12:
add textcode api for uuencode/uudecode, base64, quoted printable,
url-encoding and yenc.
0.11:
fix fmt_long (didn't count the '-'), which in turn broke
buffer_putlong
referenced wrong include file in stralloc_ready and stralloc_readyplus
man page.
0.10:
add comment to stralloc.h that explains the structure (Markus Brischke)
fix socket routines (two cut-and-paste errors)
0.9:
fmt_str did not check for out==NULL! Thanks, Uwe Ohse.
Updated to buffer to fix read buffers. Thanks, David Lichteblau.
Oops! byte_copy had a trivial and dumb typo in it that I'm unsure how
I could have missed it.
add mmap man pages.
update and add socket man pages.
don't include str.h from fmt.h
document error signalling for the mmap functions.
0.8:
BSD compatibility.
fix mmap_shared.
ranlib.
s/EPROTO/EPROTONOSUPPORT/.
0.7:
add buffer_putspace
fix b0read prototype in buffer/buffer_0*
scan_ip6 will not transparently scan IPv4 addresses and save them as
v4-mapped addresses (::ffff:127.0.0.1).
byte_copy was sped up (but made larger in the process)
0.6:
changed name to libowfat.
fixed fmt_ulong (did not output 0 correctly).
added buffer.
extended buffer API to include buffer_putulong() and friends.
oops, the read buffering was completely broken!
add mmap library (idea from Ingo Oeser)
0.5:
made subdirectories for the different libraries.
moved the sources into the corresponding subdirectory.
imported my man pages from libdjb.
removed fmt_int.c and fmt_uint.c (they are macros in fmt.h).
corrected comment in open.h for open_excl.
wrote new man pages for fmt_double, scan_double, the sign fmt_ and
scan_ routines, the whitespace and charset scan_ routines, and the
str and stralloc routines.
0.4:
implemented stralloc.
0.3:
implemented uint16, uint32 and uint64. The header files try to
define shortcut endianness conversion routines that do not convert
anything.
implemented open (I hope I got open_excl right, I couldn't find an
implementationen).
0.2:
implemented the scan, fmt and str interfaces.
added adapted fmt_double and scan_double from diet libc.
