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)
|
|
|
|
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)
|
|
|
|
0.21:
|
|
errno cleanup and man page updates (Rolf Eike Beer)

|
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 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!)

|
|
buffer_putlong

byte_copy was sped up (but made larger in the process)
|
|
|
|
0.6:
|

|
|
implementationen).
