5aefb8a6 2009-06-25 15:22:36 Fix type on freebsd sendfile. Patch from navin seshadri. Fixes bug 2811991 svn:r1330
0b22ca19 2009-05-22 19:11:48 Use ev_ssize_t in place of ssize_t *everywhere*. svn:r1309
8997f234 2009-05-21 20:59:00 Use the native "struct iovec" as our "struct evbuffer_iovec" when available, so we do not need to copy more pointers than necessary. svn:r1299
23243b8a 2009-05-19 21:39:35 Replace reserve/commit with new iovec-based interface. Add a new evbuffer_peek. svn:r1296
dc4c7b95 2009-05-15 22:44:18 Change the interface of evbuffer_add_reference: give the cleanup function more info. svn:r1294
bba69e03 2009-05-15 20:23:59 New semantics for evbuffer_cb_set_flags(). Previously, set_flags() would replace all previous user-visible flags. Now it just sets the flags, and there is a clear_flags() function to clear other flags. svn:r1293
e865eb93 2009-05-01 00:54:14 More msvc build tweaks. svn:r1262
24607a39 2009-04-29 20:48:43 Note a place we might do better about lock releasing. svn:r1252
11cab334 2009-04-28 19:08:07 Fix compile: #elif FOO is not the same as #elif defined(FOO). svn:r1245
5c4c13d8 2009-04-24 03:24:22 make sendfile work on freebsd svn:r1239
ec6bfd03 2009-04-23 21:41:53 Fix for evbuffer_read() when all data fits in penultimate chain. Previously we were reading into the next-to-last chain, but incrementing the fullness of the last. Bug found by Victor Goya. svn:r1237
a8f6d961 2009-04-17 06:56:09 Actually stop using EVBUFFER_LENGTH/DATA, and move them to buffer_compat.h svn:r1183
93d4f884 2009-04-14 20:11:10 Make buffer iocp stuff compile happily svn:r1174
0e32ba54 2009-04-13 03:06:59 Do not remove an empty chain that we have pinned for reading when we drain the whole buffer. svn:r1166
9f1a94ec 2009-04-13 03:06:47 add pin/unpin functions, and a deref-and-free pair. svn:r1165
dcda7915 2009-04-13 03:06:27 Add a reference count to evbuffers. svn:r1164
b01891fe 2009-04-13 03:06:05 Make evbuffer_commit_space trigger callbacks. svn:r1163
829b52b6 2009-04-13 03:05:46 Refactor the code that sets up iovecs for reading into its own function. iocp needs this. svn:r1162
b29b875d 2009-04-10 20:43:08 Facility to make evbuffers get their callbacks deferred. svn:r1154
747331d1 2009-04-08 03:04:39 Add freeze support to evbuffers. From the documentation: Prevent calls that modify an evbuffer from succeeding. A buffer may frozen at the front, at the back, or at both the front and the back. If the front of a buffer is frozen, operations that drain data from the front of the buffer, or that prepend data to the buffer, will fail until it is unfrozen. If the back a buffer is frozen, operations that append data from the buffer will fail until it is unfrozen. We'll use this to ensure correctness on an evbuffer when we're waiting for an overlapped IO call to finish. svn:r1143
d9086fc0 2009-04-08 03:03:59 Add a new facility to "pin" the memory in an evbuffer chain. For overlapped IO (and possibly other stuff) we need to be able to label an evbuffer_chain as "pinned", meaning that every byte in it must remain at the same address as it is now until it unpinned. This differs from being "immutable": it is okay to add data to the end of a pinned chain, so long as existing data is not moved. svn:r1142
60e0d59b 2009-04-05 02:44:17 Add locking to evbuffers. svn:r1134
f1b1bad4 2009-04-03 14:27:03 Make the new evbuffer callbacks use a new struct-based interface. The old interface would fail pretty hard when we had to batch up multiple adds and drains in a single call. svn:r1131
f90500a5 2009-04-03 01:21:36 Add a new improved search function. The old evbuffer_find didn't allow iterative searching, and forced us to repack the buffer completely every time we searched in it. The new evbuffer_search addresses both of these. As a side-effect, the evbuffer_find implementation is now a little more efficient. svn:r1130
01456265 2009-02-10 19:39:22 Explode less badly in the case where we're told to prepend/append/remove a buffer to itself. Note some API/implementation deficiencies. svn:r1110
edfdb698 2009-02-10 19:38:34 Add an assertion to evbuffer_chain_align so we can't reuse it in the future. svn:r1105
cc049bfc 2009-02-03 05:22:57 Enable (and debug) WSARecv for evbuffer iovec-like reads. The two things we were missing: the flags parameter is not optional, and an error can actually indicate a close. svn:r1100
e84c7656 2009-02-01 05:26:47 Allocate callback entries with contents 0d out. svn:r1093
8d3a10f8 2009-02-01 01:43:58 Support temporarily suspending an evbuffer callback. This is different from disabling the callback, since we want to process changes, but not just yet. svn:r1091
a0cae310 2009-01-29 03:22:47 make it so that evbuffer_add_file where we read the complete contents of the file can fail without side effects svn:r1069
66b2a7ff 2009-01-29 03:20:40 test evbuffer_add_reference svn:r1068
b85b710c 2009-01-27 22:34:36 Update copyright statements to reflect the facts that: a) this is 2009 b) niels and nick have been comaintainers for a while c) saying "all rights reserved" when you then go on to explicitly disclaim some rights is sheer cargo-cultism. svn:r1065
8889a770 2009-01-27 22:30:46 Replace all use of config.h with event-config.h. svn:r1064
9993137c 2009-01-27 21:10:31 Remove all trailing whitespace in all the source files. svn:r1063
88f2b7a0 2009-01-27 13:37:09 Fix some warnings on linux gcc with --enable-gcc-warnings svn:r1060
1757cf71 2009-01-27 06:21:12 use %zu for off_t svn:r1059
8b5bd774 2009-01-27 06:18:45 make it compile on linux svn:r1058
fdf69493 2009-01-27 06:05:38 sendfile/mmap and memory reference implementation for evbuffers svn:r1057
b93e5054 2009-01-27 05:33:39 second argument to evbuffer_pullup should be ssize_t svn:r1056
81dd04a7 2009-01-23 18:04:34 Add a "flags" field to evbuffer callbacks. For now, there is just one: enabled. This lets us avoid lots of mallocs/frees/tailq-manipulations just to turn a callback on and off. The revised bufferevent code wants this. svn:r1047
de7f7a84 2009-01-23 18:03:45 Remove in_callbacks check: allow full recursion in evbuffer callbacks. If you get yourself in an infinite loop, that's not our fault. Note this in the docs. Also reindent some docs now that my tabs match Niels's. svn:r1046
ec2f4cbc 2009-01-23 01:35:57 Move obsolete evbuffer function into include/event2/buffer_compat.h svn:r1043
c735f2b4 2009-01-23 01:11:13 Code to allow multiple callbacks per evbuffer. svn:r1042
f6eb1f81 2009-01-19 21:53:03 Change evbuffer_read implementation to split data across chunks, and use readv when available. This should make us use less space. svn:r1024
84031819 2009-01-14 22:17:31 Make some evbuffer functions const svn:r1010
3552ac1e 2009-01-14 19:39:17 Do not allow chain length to expand indefinitely. svn:r1007
6d3ed065 2009-01-14 14:58:48 Simplify evbuffer_write logic: combine nearly all of WSASend and writev cases. svn:r1004
bab8f2e1 2009-01-13 22:02:32 Fix compilation on win32 WSASend evbuffer_write() code. Still not enabled until I make sure that the unit tests test this. They _do_ pass. svn:r1003
169321c9 2009-01-13 20:26:37 Rename four internal headers to follow the -internal.h convention. svn:r1000
822ca048 2009-01-13 19:34:50 Untested (and compiled-out) evbuffer_write backend to use WSASend on win32 where we use writev on unix. svn:r998
99db0e7f 2009-01-12 20:42:19 Add a new evbuffer_write_atmost() functino to write no more than a given number of bytes to an fd. svn:r993
e711ce45 2008-06-21 06:10:10 reintroduce a memmove when there is enough misalignment to hold the new data; otherwise the size of the buffer may grow without bounds svn:r857
9586a1cb 2008-06-01 16:21:24 fix an evbuffer corruption when adding an empty evbuffer; from Scott Lamb svn:r845
c6da86ff 2008-05-12 16:44:24 r19709@catbus: nickm | 2008-05-12 12:42:48 -0400 Possible fix for [1960723] snprintf and vsnprintf return values are wrong on win32 svn:r813

8acb80b4 2008-05-08 22:51:39 r15551@tombo: nickm | 2008-05-08 14:49:20 -0400 Use _get_ convention for new accessor functions. (These are all new ones as of 2.0, I believe). svn:r799
f04497e4 2008-05-03 03:05:28 introduce evbuffer_reserve_space() and evbuffer_commit_space() to make processing in filters more efficient svn:r757

193c06a7 2008-03-31 02:04:34 fix a bug in which evbuffer_add_vfprintf would loop forever; avoid fragmentation in evbuffer_expand by increasing the size of the last buffer in the chain; as a result with have to keep track of the previous_to_last chain; provide a evbuffer_validate() function in the regression test to make sure that all evbuffer are internally consistent. svn:r699
00382110 2008-02-29 05:23:49 address nick's comments and make evbuffer_pullup more efficient svn:r680
0322ce0a 2008-02-28 18:36:03 r18486@catbus: nickm | 2008-02-28 13:35:53 -0500 Make offsetof into evutil_offsetof. Be a little more willing to call evbuffer_chain_align() from evbuffer_expand(). Clarify some docs, and add some XXX comments to note questionable areas. svn:r677
d71da6f7 2008-02-28 17:47:30 r18484@catbus: nickm | 2008-02-28 12:47:20 -0500 Use event_warn() function, not fprintf-to-stderr. svn:r676

5c70ea4c 2008-02-28 02:47:43 improved code for evbuffer; avoids memcpy svn:r674
67bf29ad 2008-02-23 06:02:04 simplify evbuffer by removing orig_buffer svn:r654
1120f04f 2007-11-25 21:53:06 r16731@catbus: nickm | 2007-11-25 16:52:53 -0500 Replace all fds on non-unix-specific APIs with evutil_socket_t, which is int on unix and intptr_t on win32. svn:r552
6773a597 2007-11-25 21:32:26 r14953@tombo: nickm | 2007-11-25 15:56:40 -0500 Replace evbuffer_readline with a more powerful evbuffer_readln that can handle more EOL styles, and that can give useful results when there are NUL characters inside the returned values. Includes regression tests. svn:r550
7eb250e9 2007-11-25 17:14:19 r14939@tombo: nickm | 2007-11-25 11:59:26 -0500 New function event_set_mem_functions to replace internal calls to malloc, free, etc with a user-supplied functions. svn:r541
4e1ec3e0 2007-11-07 21:01:26 Make all the C files in the libraries compile under MSVC 2005 Express. There are still a few warnings, and probably some subtle issues, but it's better than nothing. svn:r499
e72661d2 2007-11-07 07:33:31 r16509@catbus: nickm | 2007-11-07 02:08:32 -0500 Stop using C++ style comments. svn:r497
db43c1e1 2007-09-20 19:36:03 On win32, sockets apparently can't be used with ReadFile and WriteFile: You need send() and recv() instead. Also, you need to use ioctlsocket() with sockets, not ioctl. [Fixes evbuffer regression tests.] svn:r448
41c69fc3 2007-08-19 17:26:02 fix typo in comments svn:r399
f0ff792a 2007-06-30 18:58:34 fixes from Joerg Sonnenberger: http.c is a violation of the ctype(3) interface and an unused function. test/regress_http.c are incorrect format strings. test/regress.c uses raise(3) from signal.h. evdns.c: evdns_error_strings is unused. The GET* macros can eat the semicolon from the expression. pos is passed in as off_t, so just pass that down. When assigning negativ values to unsigned variables, an explicit cast is considered good style. svn:r367
0c280824 2007-05-23 05:20:59 support removing of http callbacks and removing of registered RPCs svn:r355
4408a5f8 2007-04-19 03:13:12 fix evbuffer_find off by one; found by Ken Cox; regression test by him and fix by me svn:r353
b5d2f9a2 2007-03-01 06:25:18 rolling back r339: evconfig.h does not work svn:r341
127c260b 2007-02-28 04:02:29 make evconfig.h available as installed header file; not really ideal but good enough for me; from Nick Mathewson svn:r339
58f42c79 2007-02-14 16:59:47 fix handling of chunked requests svn:r328
22e53c7a 2007-01-27 04:10:08 make it work on freebsd; from phil oleson svn:r314
de4e25f1 2007-01-06 02:25:50 evbuffer_find fix from Dug Song svn:r308
79d2ca8c 2006-11-10 02:16:16 fix a potential problem in multiple handling of va_list; use va_copy instead; from Alejo. svn:r251
9f7d28bb 2006-09-27 03:07:38 make it compile with mingw; from Nick svn:r235
896bf3a2 2006-02-13 02:22:48 many changes for fixing a small bug: post requests would not send the post data. I took the opportunity to reorganize a bit. svn:r201
7b78c828 2006-02-13 01:51:58 limit the amount of data bufferevents are going to consume to something reasonable; in some circumstances it could happen that libevent happily allocated 100MB in read buffers without telling the user; found by christopher maxwell - parts of these changes are from his patch. svn:r200
36bedaef 2006-01-22 05:06:14 another fix from art svn:r194
8d1317d7 2005-12-06 03:26:28 add evbuffer_add_vprintf interface from artur grabowski; add some testing svn:r188
11a40d47 2005-09-20 15:59:00 event.3 svn:r184
e1759c7b 2005-06-19 20:28:20 fix issue with signedness warnings; from Alexander von Gernler svn:r169
81bd0a06 2005-06-10 07:42:14 bufferevents would not correctly detect EOF on read; reported by Jonathan Brannan svn:r167
425fc0d5 2005-04-23 02:53:39 provide a function to read lines from buffers; comes in handy for many AscII protocols. svn:r154
5e2ba12a 2005-04-14 23:28:06 fixes from alexander von gernler svn:r148
32bed8f9 2005-04-01 04:20:39 build fixes from nick mathewson svn:r139
fbdaf3ab 2005-03-29 07:03:10 debugging callbacks from Nick Mathewson <nickm@freehaven.net> svn:r136
6db3da27 2004-07-19 06:18:10 should work a little bit better with solaris compiler svn:r111
44d88ea6 2004-07-13 08:02:45 change evbuffer_read so that it reads directly into the memory allocated to the evbuffer; this avoids one unnecessary data copy. svn:r110
de5fc619 2004-06-11 04:42:56 make it compile on systems without vasprintf svn:r107
025d1bc2 2004-05-24 00:19:52 fix some of the windows compile issues; make buffer.c faster; support signals via pipes. svn:r105
