9fde5189 2016-02-15 00:12:54 http: lingering close (like nginx have) for entity-too-large By lingering close I mean something what nginx have for this name, by this term I mean that we need to read all the body even if it's size greater then `max_body_size`, otherwise browsers on win32 (including chrome) failed read the http status - entity-too-large (while on linux chrome for instance are good), and also this includes badly written http clients. Refs: #321 v2: do this only under EVHTTP_SERVER_LINGERING_CLOSE
680742e1 2016-02-10 14:43:18 http: read server response even after server closed the connection Otherwise if we will try to write more data than server can accept (see `evhttp_set_max_body_size()` for libevent server) we will get `EPIPE` and will not try to read server's response which must contain 400 error for now (which is not strictly correct though, it must 413). ``` $ strace regress --no-fork http/data_length_constraints ... connect(10, {sa_family=AF_INET, sin_port=htons(43988), sin_addr=inet_addr("127.0.0.1")}, 16) = -1 EINPROGRESS (Operation now in progress) ... writev(10, [{"POST / HTTP/1.1\r\nHost: somehost\r"..., 60}, {"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"..., 16324}], 2) = 16384 epoll_wait(5, [{EPOLLOUT, {u32=10, u64=10}}, {EPOLLIN, {u32=11, u64=11}}], 32, 50000) = 2 writev(10, [{"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"..., 16384}], 1) = 16384 ioctl(11, FIONREAD, [32768]) = 0 readv(11, [{"POST / HTTP/1.1\r\nHost: somehost\r"..., 4096}], 1) = 4096 epoll_ctl(5, EPOLL_CTL_DEL, 11, 0x7fff09d41e50) = 0 epoll_ctl(5, EPOLL_CTL_ADD, 11, {EPOLLOUT, {u32=11, u64=11}}) = 0 epoll_wait(5, [{EPOLLOUT, {u32=10, u64=10}}, {EPOLLOUT, {u32=11, u64=11}}], 32, 50000) = 2 writev(10, [{"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"..., 16384}], 1) = 16384 writev(11, [{"HTTP/1.1 400 Bad Request\r\nConten"..., 129}, {"<HTML><HEAD>\n<TITLE>400 Bad Requ"..., 94}], 2) = 223 epoll_ctl(5, EPOLL_CTL_DEL, 11, 0x7fff09d42080) = 0 shutdown(11, SHUT_WR) = 0 close(11) = 0 epoll_wait(5, [{EPOLLOUT|EPOLLERR|EPOLLHUP, {u32=10, u64=10}}], 32, 50000) = 1 writev(10, [{"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"..., 16384}], 1) = -1 EPIPE (Broken pipe) --- SIGPIPE {si_signo=SIGPIPE, si_code=SI_USER, si_pid=13954, si_uid=1000} --- epoll_ctl(5, EPOLL_CTL_DEL, 10, 0x7fff09d42010) = 0 shutdown(10, SHUT_WR) = -1 ENOTCONN (Transport endpoint is not connected) close(10) = 0 write(1, "\n FAIL ../test/regress_http.c:3"..., 37 ``` Careful reader can ask why it send error even when it didn't read `evcon->max_body_size`, and the answer will be checks for `evcon->max_body_size against `Content-Length` header, which contains ~8MB (-2 bytes). And also if we will not drain the output buffer than we will send buffer that we didn't send in previous request and instead of sending method via `evhttp_make_header()`.

Also extra check for EVHTTP_CON_PUBLIC_FLAGS_END, in case somebody forgot about this (implementer I mean). Refs: #182

a264da86 2015-12-20 00:57:50 Revert "The Windows socket type is defined as SOCKET."
c9e6c3d7 2015-12-16 11:17:36 The Windows socket type is defined as SOCKET. Under the hood it's an unsigned rather than a signed type and whilst C compilers are largely happy with this C++ compilers tend to be fussy about class function signatures which makes C++ usage of libevent problematic.

a50f5f0a 2015-01-01 06:27:31 http: reuse connected address only with EVHTTP_CON_REUSE_CONNECTED_ADDR
8bb38425 2014-11-15 21:46:11 bufferevent: move conn_address out from http into bufferevent In http the only case when when we could store it is when we already connected, *but* if we are doing request using domain name, then we need to do request to nameserver to get IP address, and this is handled by bufferevent. So when we have IP address (from nameserver) and don't have connection to this IP address, we could already cache it to avoid extra DNS requests (since UDP is slow), and we can't do this from http layer, only from bufferevent.
dc33c783 2014-12-02 15:05:59 be: make @sa const for bufferevent_socket_connect()
043ae748 2015-05-11 12:06:01 Fix garbage value in socketpair util function, stdint? * Fixed an issue with evutil_ersatz_socketpair_, listen_addr could all be compared against with agarbage values. So just memset it before using it anywhere. * Nick might punch me in the face, but if we have stdint.h; (as in EVENT__HAVE_STDINT_H is defined), might as well use those instead of the manual [U]INT[X}_MAX/MIN muck in there now.

b1b69ac7 2014-01-17 23:20:42 Implemented EV_CLOSED event for epoll backend (EPOLLRDHUP). - Added new EV_CLOSED event - detects premature connection close by clients without the necessity of reading all the pending data. Does not depend on EV_READ and/or EV_WRITE. - Added new EV_FEATURE_EARLY_CLOSED feature for epoll. Must be supported for listening to EV_CLOSED event. - Added new regression test: test-closed.c - All regression tests passed (test/regress and test/test.sh) - strace output of test-closed using EV_CLOSED: socketpair(PF_LOCAL, SOCK_STREAM, 0, [6, 7]) = 0 sendto(6, "test string\0", 12, 0, NULL, 0) = 12 shutdown(6, SHUT_WR) = 0 epoll_ctl(3, EPOLL_CTL_ADD, 7, {EPOLLRDHUP, {u32=7, u64=7}}) = 0 epoll_wait(3, {{EPOLLRDHUP, {u32=7, u64=7}}}, 32, 3000) = 1 epoll_ctl(3, EPOLL_CTL_MOD, 7, {EPOLLRDHUP, {u32=7, u64=7}}) = 0 fstat(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 4), ...}) mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYM... write(1, "closed_cb: detected connection close "..., 45) = 45

45eba6ff 2013-12-06 10:50:17 Rename flush_outdated_host_addresses to clear_host_addresses "flush" can imply writing something out to a file or connection before clearing it; "clear" always means "remove". It's also potentially misleading to say "outdated" here, since the function removes _all_ addresses regardless, not just certain outdated ones. Also, don't free the lock in this function. Also reindent the function.
f03d3535 2013-12-06 17:06:20 bug fix for issues #293 evdns_base_load_hosts doesn't remove outdated addresses As mentioned at https://sourceforge.net/p/levent/bugs/293/ created a small function "evdns_base_flush_outdated_host_addresses" which removes all the previous host addresses, if user wants to clean up the list of hosts can call and use this function. Defination of this function is part of another patch.

8d8decf1 2009-05-02 20:40:11 Add a variant of evhttp_send_reply_chunk() with a callback on evhttp_write_buffer() evhttp_write_buffer() used by evhttp_send_reply_chunk() can take callback executed when (part of) the buffer has been written. Using this callback to schedule the next chunk avoids buffering large amounts of data in memory.
0c7f0405 2013-10-01 19:12:13 http: implement new evhttp_connection_get_addr() api. Basically tcp final handshake looks like this: (C - client, S - server) ACK[C] - FIN/ACK[S] - FIN/ACK[S] - ACK [C] However there are servers, that didn't close connection like this, while it is still _considered_ as valid, and using libevent http layer we can do requests to such servers. Modified handshake: (C - client, S - server) ACK[C] - RST/ACK[S] - RST/ACK[S] And in this case we can't extract IP address from socket, because it is already closed, and getpeername() will return: "transport endpoint is not connected". So we need to store address that we are connecting to, after we know it, and that is what this patch do. I have reproduced it, however it have some extra packages. (I will try to fix it) https://github.com/azat/nfq-examples/blob/master/nfqnl_rst_fin.c

e9ebef83 2013-04-09 21:14:52 Always run pending finalizers when event_base_free() is called There was actually a bug in the original version of this: it tried to run the finalizers after (potentially) setting current_base to NULL; but those finalizers could themselves (potentially) be invoking stuff that needed to know about the current event_base. So the right time to do it is _before_ clearing current_base.

7b077194 2013-03-21 13:55:40 Add new error_cb for actual reporting of HTTP request errors. It is useful to know why you callback called with NULL (i.e. it failed), for example if you set max_body with evhttp_connection_set_max_body_size() you must know that it failed because of body was longer than this size. (Commit message tweaked by Nick)
6b7fa620 2013-03-27 20:15:46 evdns: New flag to make evdns not prevent the event loop from exiting Here is the brief description of problem: When you are use evdns to resolve domains to IP adresses (see ./sample/dns-example) you loop never returns from event_base_dispatch(), and because of this the program will never terminated. Because existing programs may be depending on the old behavior, we only apply the fix when evdns_base_new() is created with a new flag - EVDNS_BASE_DISABLE_WHEN_INACTIVE. (Commit message edited by Nick while squashing the branch.)

c17dd591 2011-07-15 11:10:54 Free dangling event_once objects on event_base_free() This patch makes us keep event_once objects in a doubly linked list so we can free any once that haven't triggered when we call event_base_free().
81b6209e 2012-11-10 11:22:15 Fix event_dlist definition when sys/queue not included This header adds TAILQ_HEAD and TAILQ_ENTRY if sys/queue is not included. There is a similar macro that adds LIST_ENTRY but not LIST_HEAD, even though LIST_HEAD is used later. This change pulls in the correct definition (swiped from sys/queue) for LIST_HEAD and cleans up the one spot where it is used. The change can be tested by adding #undef LIST_HEAD #undef LIST_ENTRY right before the #ifndef checks and removing #define EVENT_DEFINED_LISTENTRY_ #define EVENT_DEFINED_LISTHEAD_ so that the macros persist later.
