  1. 0.33:
  2. 0.32:
  3. remove OpenBSD #warning (obsd maintainer says no longer needed)
  4. move headers to <libowfat/> upon install
  5. fix fmt_ip6 (Erwin Hoffmann)
  6. add MSG_ZEROCOPY support (only used for buffers >8k)
  7. use writev in buffer_put for a slight perf improvement
  8. add experimental iom API for multithreaded I/O multiplexing (in io.h)
  9. 0.31:
  10. special case buffer_get_token with token length 1 through memccpy (almost 4x speedup)
  11. test for pread and use it instead of lseek+read in cdb and io_mmapwritefile
  12. add mmap_readat (like mmap_read but open by fd, not by name)
  13. add fmt_iso8601 and scan_iso8601 (time_t -> "2014-05-27T19:22:16Z")
  14. add fmt_netstring and scan_netstring (http://cr.yp.to/proto/netstrings.txt)
  15. add (fmt|scan)_varint and (fmt|scan)_pb_* (binary marshaling ala protocol buffers)
  16. 0.30:
  17. add compiletimeassert.h
  18. add haveuint128.h
  19. byte.h now defines UNALIGNED_ACCESS_OK on x86
  20. add scan_ulongn, scan_8longn, scan_xlongn, scan_longn, scan_netstring
  21. change buffer to have a destructor function pointer
  22. 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)
  23. fmt_pad and fmt_fill fail more gracefully when srclen > maxlen
  24. You can now say $ make WERROR=-Werror (compiling t.c may fail but that's strictly speaking not part of the library)
  25. scan_html now decodes HTML entities based on the actual w3c list (from entities.json, say gmake update to fetch the current version)
  26. 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)
  27. 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.
  28. scan_*long, scan_*int, scan_*short now properly abort if the number would not fit
  29. SECURITY: check for integer overflow in stralloc_ready
  30. switch io_fds from array to newly implemented (hopefully thread-safe) iarray
  31. switch epoll from level triggering to edge triggering
  32. introduce io_eagain_read and io_eagain_write (discontinue using io_eagain plz)
  33. fix buffer_get
  34. add fmt_html_tagarg, fmt_xml, scan_html_tagarg
  35. add socket_fastopen, socket_fastopen_connect4, socket_fastopen_connect6 and socket_quickack
  36. on Linux, in iob_send, if MSG_MORE is defined, and the request type
  37. lends itself to it, used sendto/sendmsg with MSG_MORE instead of
  38. TCP_CORK (saves two syscalls)
  39. add io_fd_flags so the caller can tell io_fd whether the socket is blocking
  40. (saves one fcntl syscall)
  41. more constness for stralloc and buffer
  42. mmap_read/mmap_shared on zero length files no longer fail but return a
  43. zero length buffer
  44. if SOCK_NONBLOCK is defined, use it instead of socket+fcntl
  45. ... but if errno==EINVAL still fall back to socket+fcntl (Robert Henney)
  46. SECURITY: fix botched integer overflow handling logic in stralloc_ready (Giorgio)
  47. add critbit
  48. 0.29:
  49. save 8 bytes in taia.h for 64-bit systems
  50. add buffer_tosa (buffer writing to auto-growing stralloc)
  51. add iarray
  52. support SCTP in addition to TCP
  53. fix io_receivefd so the incoming buffer is only 1 byte; io_passfd
  54. sends only one byte, so we might receive (and discard) other data if
  55. we try to read more (Stefan Bühler, from the lightttpd project)
  56. add io_fd_canwrite (like io_fd but assume the fd is writable)
  57. save a few syscalls here and there
  58. add awesome hack in isset.h (comex, Linus Torvalds)
  59. add byte_equal_notimingattack
  60. 0.28:
  61. add uint64 pack and unpack routines
  62. fix subtle typo in sub_of (David Sirovsky)
  63. work around gcc bugs
  64. 0.27:
  65. add fmt_strm
  66. add iob_addbuf_munmap
  67. add socket_deferaccept
  68. catch one more case in umult64 (Tomi Jylhä-Ollila)
  69. 0.26:
  70. fix really pathological case where io_timeouted would never
  71. start over from the beginning because always new accept()ed
  72. connections came in and got newer, higher descriptors since the last
  73. io_timeouted loop. (Dirk Engling)
  74. add some int overflow check macros to rangecheck.h
  75. fmt_ip6 compresses at best spot, not at first spot (Nikola Vladov)
  76. use inttypes.h to declare ints in uint*.h
  77. escape more in fmt_ldapescape
  78. try to catch malicious input in textcode fmt_* functions
  79. fmt_xlonglong was utterly broken (Johannes Vetter)
  80. 0.25:
  81. array_allocate no longer truncates the array
  82. array_get now not only checks whether the element fits in the
  83. allocates space, it also needs to be in the initialized space.
  84. add -D_REENTRANT to CFLAGS so libowfat can be used in multi-threaded
  85. programs
  86. further Windoze support (test/io5.c works, gatling still doesn't)
  87. This is just to get gatling to work, I may remove it again after
  88. that.
  89. implement Nikola's idea to remove limit number of strings in errmsg
  90. add taia_half
  91. add cdb
  92. add rangecheck.h
  93. add io_block
  94. make socket_(tc|ud)p[46] actually return non-blocking sockets as
  95. documented (Richard Lyons)
  96. fix for NetBSD 3.0 (Their /sys/types.h actually does not define u_char
  97. unless you #define _NETBSD_SOURCE, and then their CMSG_* macros use
  98. it. This is horrible even by OpenBSD standards)
  99. remove support for ip6.int (it's no longer delegated)
  100. add asm versions of imult64 and umult64 for x86_64
  101. (22 cycles -> 12 cycles on my Athlon 64)
  102. use size_t and ssize_t instead of unsigned long et al
  103. add iob_bytesleft
  104. don't leak memory in test/httpd
  105. 0.24:
  106. fix scan_to_sa (Tim Lorenz)
  107. turns out we can not do file descriptor passing on OpenBSD
  108. if _XOPEN_SOURCE is defined, which is needed for Solaris.
  109. OpenBSD sucks. I checked in a _really_ kludge now. Please do not
  110. use OpenBSD if you have a choice. Or Solaris, for that matter.
  111. turns out the imult routines (which I never used) were incorrect.
  112. Noted by Matthew Dempsky
  113. open_* from open.h now open in large file mode
  114. 0.23:
  115. also recognize EPFNOSUPPORT as EAFNOSUPPORT (groan)
  116. fix a few man pages
  117. optimize fmt_base64 (Dan Gundlach)
  118. gcc 4 cleanups (mostly unsigned char* vs char*)
  119. fix scan_xlong, scan_xlonglong and scan_8long
  120. remove a few gcc 4 warnings
  121. work around freebsd 5.4 brokenness (if you don't have IPv6 in the
  122. kernel, socket(PF_INET6,SOCK_STREAM,0) returns EPROTONOSUPPORT
  123. instead of EPFNOSUPPORT, which basically says "yeah, I know IPv6,
  124. but TCP? never heard of it")
  125. remove even more warnings
  126. 64-bit cleanliness issue with auto-NULL-appending macros
  127. IRIX compatibility (yuck!)
  128. 0.22:
  129. uh, the scope_id detection #defined the wrong constant. libowfat
  130. always thought there was no scope_id. Oops.
  131. #include <unistd.h> in io/io_sendfile.c (broken OpenBSD, thx Rob)
  132. add scan_urlencoded2 (like scan_urlencoded but will not convert '+' to
  133. ' '; needed for web servers, so they can serve libstdc++.tar.gz)
  134. fix iob_write to handle failure properly
  135. document that the iob_write callback should limit itself
  136. fix mmap_shared
  137. add iob_free, add man pages for iob_free and iob_reset
  138. fix descriptor leak in iob_addfile_close if the range was 0 (oops)
  139. 0.21:
  140. errno cleanup and man page updates (Rolf Eike Beer)
  141. implement iob_prefetch with madvise MADV_WILLNEED if it's defined
  142. extend API To read line/token to stralloc to allow clearing the
  143. stralloc first.
  144. add stralloc_zero to clear a stralloc
  145. add buffer_putsflush
  146. add stralloc_catm and stralloc_copym
  147. add buffer_putm and buffer_putmflush
  148. cleanups in stralloc and buffer:
  149. int -> long for sizes
  150. char -> unsigned char for strings
  151. buffer_getline is now a function, not a macro
  152. add iob_write (send io batch through callback, e.g. for SSL)
  153. add errmsg_info and errmsg_infosys to write to stdout instead
  154. epoll fix (how could this ever work?)
  155. 0.20:
  156. add errmsg API
  157. work around broken Linux sendfile API (offset 64-bit but count 32-bit)
  158. add io_appendfile, io_readwritefile
  159. support ip6.arpa in addition to ip6.int in dns_name (adds one
  160. parameter to dns_name6_domain and two constants in dns.h)
  161. Solaris compatibility for io_passfd and io_receivefd
  162. 0.19.2:
  163. for some reason, a botched dependency slipped in the the Makefile
  164. 0.19.1:
  165. oops, I botched havealloca.h, which was not generated but static
  166. Now it is generated.
  167. 0.19:
  168. add io_socketpair
  169. add io_passfd and io_receivefd (and test/fdpassing.c)
  170. io_trywrite and io_waitwrite not ignore SIGPIPE
  171. add man pages for libio, safemult
  172. fix possible signal race in io_tryread and io_trywrite (Scott Lamb)
  173. fix byte_rchr return value (Marcus Winkler)
  174. fix bug in mmap code path of io_sendfile (David Leadbeater)
  175. 0.18:
  176. make libowfat compile on BSD again (sorry, and thanks to everyone who
  177. sent me a patch :-D)
  178. add iob_addfile_close, needed for gatling 0.5+
  179. add test/client and test/server, two simple TCP shell interfaces
  180. 0.17:
  181. add Linux SIGIO support to IO
  182. expand IO api to be able to cope with edge triggered event
  183. notification: introduce io_eagain
  184. the integer scan routines should only write *dest if they actually
  185. scanned something
  186. io_sendfile and iob_send should return -1 to -3 just like io_trywrite
  187. make io_waituntil actually take an "until", not a "how long"
  188. turns out that BSD kqueue is actually Free/OpenBSD kqueue -- NetBSD
  189. doesn't have it. That means I'll need some adaptive two-threads-
  190. running-poll approach to get C10k type scalability on NetBSD :-(
  191. turns out that BSD sendfile is actually FreeBSD sendfile -- neither
  192. OpenBSD nor NetBSD have it (as of 3.4 and 1.6.1). That means I'll
  193. need to try using mmap on OpenBSD and NetBSD to get zero-copy TCP.
  194. guard against same event being signalled twice (confused our list
  195. handling)
  196. add support for Solaris /dev/poll
  197. add lose32 support (broken, please don't use!)
  198. head -1 -> head -n 1
  199. apending 0 bytes to an empty array would fail it
  200. remove socket_sendfile now that we have io_sendfile
  201. break out alloca #include dependency into havealloca.h
  202. support HP-UX sendfile64 (thanks to Rolf Eike Beer)
  203. support Solaris sendfile64
  204. support MacOS X sendfile (and comment it out again, the headers
  205. declare it but it's not actually there) (thanks to Bernhard Schmidt)
  206. support AIX 5 (thanks to Lutz Chwala and Arthur Erhardt)
  207. fix ip6_fmt (martin paljak)

  211. change length counters from int to long for 64-bit platforms
  212. add array API from http://cr.yp.to/lib/array.html
  213. oops, had a declaration and man page for taia_addsec but not the
  214. function itself
  215. add buffer functions to write strerror(errno)
  216. add io API supporting poll, epoll and kqueue
  217. remove obsolete "extern" from header files
  218. add iob API to send several buffers and files in one batch
  219. 0.15:
  220. man page update (document stralloc return values)
  221. add stralloc_chop and stralloc_chomp
  222. add buffer_putsa, buffer_get_token_sa and buffer_getline_sa

  232. add fmt_human and fmt_humank (format numbers ala ls -H/-h)
  233. add fmt_httpdate and scan_httpdate
  234. fix typo breaking buffer_GETC in buffer (Marcus Winkler)
  235. fix typo breaking fmt_long for dest==NULL
  236. add fmt_*longlong()
  237. add range check to scan_ulong, scan_ulonglong, scan_uint and
  238. scan_ushort
  239. extended socket API; you can now pass NULL for results you don't want
  240. rename Makefile to GNUmakefile; create Makefile target
  241. add buffer_get_token_pred and buffer_get_token_sa_pred
  242. 0.14:
  243. avoid bus errors in byte_copy

  259. 0.11:
  260. fix fmt_long (didn't count the '-'), which in turn broke
  261. buffer_putlong
  262. referenced wrong include file in stralloc_ready and stralloc_readyplus

  264. 0.10:
  265. add comment to stralloc.h that explains the structure (Markus Brischke)
  266. fix socket routines (two cut-and-paste errors)
  267. 0.9:
  268. fmt_str did not check for out==NULL! Thanks, Uwe Ohse.
  269. Updated to buffer to fix read buffers. Thanks, David Lichteblau.
