4e6375e8 | 2023-03-05 16:56:56 | Always have evutil_secure_rng_add_bytes available (#1427) When libevent doesn't provide random the arc4 function, but they come from libc, there is no need to call this function, so make it do nothing. Fixes: #1393 | |
 |
f9134df7 | 2023-02-04 15:00:48 | Add LEV_OPT_BIND_IPV4_AND_IPV6 flag (#1400) Libevent introduced the LEV_OPT_BIND_IPV6ONLY to pass to evconnlistener_new_bind to make it automatically set the underlying socket as accepting ipv6 requests. This works fine on posix compliant platforms as by the standard every new AF_INET6 socket is created as both supporting ipv6 and ipv4 connections. But on windows the default is the opposite, with the flag IPV6_V6ONLY being always enabled by default. This makes creating a listener to supports both protocols a bit more tricky as winsock doesn't allow changing this flag after evconnlistener_new_bind does all the initial setup because as stated in the docs, you can't change it after the sonnect connected, so one would have to manually create the socket beforehand and set the flag and then call evconnlistener_new with the socket itself. It would be nice to have libevent keep a consistent behaviour across the platforms in this scenario, maybe or by making it always set IPV6_V6ONLY to false unless LEV_OPT_BIND_IPV6ONLY is passed, in which case it's set to true, or add another flag to forcefully set it to false and keep the system dependent behaviour as default. So this patch add new option for libevent listeners to bind to both - LEV_OPT_BIND_IPV4_AND_IPV6 | |

e8313084 | 2022-09-12 22:16:56 | Add minimal WebSocket server implementation for evhttp (#1322) This adds few functions to use evhttp-based webserver to handle incoming WebSockets connections. We've tried to use both libevent and libwebsockets in our application, but found that we need to have different ports at the same time to handle standard HTTP and WebSockets traffic. This change can help to stick only with libevent library. Implementation was inspired by modified Libevent source code in ipush project [1]. [1]: https://github.com/sqfasd/ipush/tree/master/deps/libevent-2.0.21-stable Also, WebSocket-based chat server was added as a sample. | |

617ba838 | 2021-01-09 17:19:27 | evdns: add max-probe-timeout/probe-backoff-factor settings I recently found that when the network status changed when calling bufferevent_socket_connect_hostname (e.g. switching between several WIFIs), all DNS servers would fail, and the timeout of probe would be very long if there were many DNS requests. I want libevent to support manual setting of MAX_PROBE_TIMEOUT and TIMEOUT_BACKOFF_FACTOR So move hardcoded MAX_PROBE_TIMEOUT and TIMEOUT_BACKOFF_FACTOR into struct, and allow changing them. | |

afa66ea4 | 2019-09-04 00:56:20 | http: eliminate redundant bev fd manipulating and caching [WIP] At the very beginning we reset the bufferevent fd (if bev has it), which is not a good idea, since if user passes bufferevent with existing fd he has some intention. So we need to: - use BEV_OPT_CLOSE_ON_FREE for default bufferevent_socket_new() (to avoid manual shutdown/closee) - drop getsockopt(SOL_SOCKET, SO_ERROR), since bufferevent already has evutil_socket_finished_connecting_() - drop supperior bufferevent_setfd(bev, -1) in evhttp_connection_connect_() Closes: #795 Refs: #875 | |

02905413 | 2016-02-09 18:01:00 | Add callback support for error pages The existing error pages are very basic and don't allow for multi-lingual support or for conformity with other pages in a web site. The aim of the callback functionality is to allow custom error pages to be supported for calls to evhttp_send_error() by both calling applications and Libevent itself. A backward-incompatible change has been made to the title of error pages sent by evhttp_send_error(). The original version of the function used the reason argument as part of the title. That might have unforeseen side-effects if it contains HTML tags. Therefore the title has been changed to always use the standard status text. An example of the error callback can be found in this [version](https://github.com/libevent/libevent/files/123607/http-server.zip) of the 'http-server' sample. It will output error pages with very bright backgrounds, the error code using a very large font size and the reason. Closes: #323 (cherr-picked from PR) | |

8dcb94a4 | 2016-01-08 13:36:20 | Added http method extending User can define his own response method by calling evhttp_set_ext_method_cmp() on the struct http, or evhttp_connection_set_ext_method_cmp() on the connection. We expose a new stucture `evhttp_ext_method` which is passed to the callback if it's set. So any field can be modified, with some exceptions (in evhttp_method_): If the cmp function is set, it has the ability to modify method, and flags. Other fields will be ignored. Flags returned are OR'd with the current flags. Based on changes to the #282 from: Mark Ellzey <socket@gmail.com> | |

5f87be42 | 2019-02-25 11:59:15 | Define `_GNU_SOURCE` properly/consistently per autoconf Although `_GNU_SOURCE` can be defined as an arbitrary #define per the glibc docs [1], it's best to define it in a manner consistent with the way that autoconf defines it, i.e., `1`. While this shouldn't matter in most cases, it does when the headers from other projects follow the poorly defined GNU convention implemented by autoconf and are included after the libevent's util.h header. An example failure with clang, similar to the failure I encountered, is as follows: ``` $ printf "#define _GNU_SOURCE\n#define _GNU_SOURCE 1" | clang -c -x c - <stdin>:2:9: warning: '_GNU_SOURCE' macro redefined [-Wmacro-redefined] ^ <stdin>:1:9: note: previous definition is here ^ 1 warning generated. ``` This happened when compiling python [2] with a stale homebrew util.h file from libevent (which admittedly would not happen in a correct libevent install, as the header should be installed under /usr/local/include/event2/util.h). However, if both headers had been combined (which is more likely), it would have failed as shown above. Removing the ad hoc definition unbreaks compiling python's pyconfig.h.in header when included after util.h from libevent. 1. http://www.gnu.org/software/libc/manual/html_node/Feature-Test-Macros.html 2. https://github.com/python/cpython/blob/master/configure.ac#L126 Closes: #773 (cherry-picked) Signed-off-by: Enji Cooper <yaneurabeya@gmail.com> | |

5a455acd | 2018-10-17 23:21:17 | Fix hangs due to watermarks overruns in bufferevents implementations Some implementations of bufferevents (for example openssl) can overrun read high watermark. And after this if user callback will not drain enough data it will be suspended (i.e. it will not be runned again anymore). This is not the expecting behaviour as one may guess, since in this case the data will never be read. Hence once we detected that the watermark exceeded (even after calling user callback) we will schedule the callback again. This also can be fixed in bufferevent openssl implementation (by strictly limiting how much data is added to the read buffer according to read high watermark), but since this data is already available (and in memory) there is no point in doing so. | |

1af80176 | 2018-04-30 18:13:45 | [core] re-order fields in struct event for memory efficiency The sizeof `struct event` can reduced on both 32 bit and 64 bit systems by moving the 4 bytes that make up `ev_events` and `ev_res` below `ev_fd`, before `struct event_base * ev_base;` since our compiler wouldn't dare do such a thing (it instead will pad twice, whereas it only needs to be padded once) ```C struct event { /* OFFS | SZ Bytes | Total Bytes | START - END */ struct event_callback ev_evcallback; /* 0x0 | 40 | 40 | 0x0 - 0x28 */ union { /* 0x28 | ----------- | ----------- | ------------ */ TAILQ_ENTRY(event) ev_next_with_common_timeout; /* | ((16)) | | */ int min_heap_idx; /* | ((04)) | | */ } ev_timeout_pos; /* | 16 | 56 | 0x28 - 0x38 */ int ev_fd; /* 0x38 | 04 | 60 | 0x38 - 0x3c */ ``` Since the next field is 8 bytes in length, and we are up to 60 bytes, `ev_fd` ends up being padded (4 more bytes on 64b). ```C /* --- 1 byte gap HERE ---> 1 | <61> */ /* --- 1 byte gap HERE ---> 1 | <62> */ /* --- 1 byte gap HERE ---> 1 | <63> */ /* --- 1 byte gap HERE ---> 1 | <64> */ struct event_base * ev_base; /* 0x3c | 8 | 68 | 0x3c - 0x40 */ union { /* 0x40 | ------------ | ---------- | ------------ */ struct { /* | ------------ | | */ LIST_ENTRY (event) ev_io_next; /* | ((16+ | | */ struct timeval ev_timeout; /* | 16)) | | */ } ev_io; /* | ((32)) | | */ struct { /* | ------------ | | */ LIST_ENTRY (event) ev_signal_next; /* | ((16+ | | */ short ev_ncalls; /* | 02+ | | */ short * ev_pncalls; /* | 08)) | | */ } ev_signal; /* | ((26)) | | */ } ev_; /* 0x60 | 32 | 100 | 0x40 - 0x60 */ short ev_events; /* 0x60 | 2 | 102 | 0x60 - 0x62 */ short ev_res; /* 0x62 | 2 | 104 | 0x62 - 0x64 */ ``` We now hit another line, `struct timeval` is 16 bytes on 64b arch, so we have 4 more bytes of padding on `ev_res`. ```C /* --- 1 byte gap HERE --- */ /* --- 1 byte gap HERE --- */ /* --- 1 byte gap HERE --- */ /* --- 1 byte gap HERE --- */ struct timeval ev_timeout; /* 0x64 | 16 | 120 | 0x64 - 0x74 */ }; ``` After moving `ev_events` and `ev_res` below `ev_fd` we have something a bit more optimal: ```C struct event2 { /* OFFS | SZ / Bytes | RSUM Bytes | START - END */ struct event_callback ev_evcallback; /* 0x0 | 40 | 40 | 0x0 - 0x28 */ union { /* 0x28 | ------------ | ---------- | ------------ */ TAILQ_ENTRY(event) ev_next_with_common_timeout; /* | ((16)) | | */ int min_heap_idx; /* | ((04)) | | */ } ev_timeout_pos; /* | 16 | 56 | 0x28 - 0x38 */ int ev_fd; /* 0x38 | 4 | 60 | 0x38 - 0x3c */ short ev_events; /* 0x3c | 2 | 62 | 0x3c - 0x3e */ short ev_res; /* 0x3e | 2 | 64 | 0x3e - 0x40 */ struct event_base * ev_base; /* 0x40 | 8 | 74 | 0x40 - 0x48 */ union { /* 0x48 | ------------ | ---------- | ------------ */ struct { /* | ------------ | | */ LIST_ENTRY (event) ev_io_next; /* | ((16+ | | */ struct timeval ev_timeout; /* | 16)) | | */ } ev_io; /* | ((32)) | | */ struct { /* | ------------ | | */ LIST_ENTRY (event) ev_signal_next; /* | ((16+ | | */ short ev_ncalls; /* | 02+ | | */ short * ev_pncalls; /* | 08)) | | */ } ev_signal; /* | ((26)) | | */ } ev_; /* | 32 | 106 | 0x48 - 0x68 */ struct timeval ev_timeout; /* 0x68 | 16 | 120 | 0x68 - 0x78 */ }; ``` We still have a gap here, but the first was removed. Again, we can save 8 bytes on both 32 and 64 word sizes (32/64 byte cacheline).

This is important, as otherwise clients can easily exhaust the file descriptors available on a libevent HTTP server, which can cause problems in other code which does not handle EMFILE well: for example, see https://github.com/bitcoin/bitcoin/issues/11368 Closes: #578 (patch cherry picked) | |
