Zonr Chang c6b1ec12 2016-08-24T17:16:32 Fix evhttp_uriencode() regression. http_uriencode_test() (in test/regress_http.c) has been failed after 72afe4c as "hello\0world" is encoded to "hello" instead of "hello%00world". This is because of a misplaced overflow check which causes the non-negative "size" specified in parameter being ignored in within-bound URI. Fixes: #392
Mark Ellzey e94250c8 2016-08-14T14:03:56 removed unused vars
Mark Ellzey 72afe4c9 2016-08-14T14:00:02 pointer overflow checks for evhttp_uriencode Check to make sure pointer math is all OK.

Azat Khuzhin f0e13411 2016-03-22T23:36:19 http: avoid leaking of fd in evhttp_connection_free() Since we do close fd there if we don't have BEV_OPT_CLOSE_ON_FREE, and evcon->fd can be incorrect (non -1), so just get it from the underlying bufferevent to fix this.

Azat Khuzhin d4054928 2016-03-11T20:17:51 http: make fallback for EVHTTP_CON_READ_ON_WRITE_ERROR more cleaner
Azat Khuzhin 2ff164ab 2016-03-11T19:58:05 http: fix EVHTTP_CON_READ_ON_WRITE_ERROR when it doesn't supported by OS For example win32 doesn't accept such things (maybe via overloaded IO, I'm not sure), also I looked into curl and seems that the behaviour is the same (IOW like with EVHTTP_CON_READ_ON_WRITE_ERROR on linux/win32). Fixes: https://ci.appveyor.com/project/nmathewson/libevent/build/2.1.5.216#L499 (win32) Fixes: 680742e1665b85487f10c0ef3df021e3b8e98634 ("http: read server response even after server closed the connection") v2: v0 was just removing that flag, i.e. make it deprecated and set_flags() will return -1

Azat Khuzhin 0b46b39e 2016-03-11T13:08:28 http: fix "Expect: 100-continue" client side Instead of sending data always at the beginning of the request wait until the server will respond with "HTTP/1.1 100 Continue". Before this patch server do send "HTTP/1.1 100 Continue" but client always send post data even without waiting server response. P.S. this patch also touches some not 100% related tab-align issues.

Azat Khuzhin 9fde5189 2016-02-15T00:12:54 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.

Ed Schouten c1404b56 2015-08-26T10:06:09 Include <sys/ioctl.h>, <sys/resource.h> and <sys/wait.h> optionally. Though CloudABI implements a very large part of POSIX, it does not provide these header files, for the reason that there is no raw device access, no resource limiting and no access to the global process table through wait(). It looks like these header files are not actually needed in theory. There don't seem to be any constructs in these source files that use these features, but I suspect they might still be required on some systems.

Azat Khuzhin 7ed02ac1 2015-09-08T16:40:55 http: fix detecting EOF without write Before this patch http server don't knows when client disconnected until it will try to write to it, IOW to detect is client still alive you need to write something to client socket, however it is not convenient since it requires to store all clients somewhere and poll them periodically, and I don't see any regressions if we will leave EV_READ always (like libevhtp do), since we already reset read callback in evhttp_write_buffer() (see http/write_during_read). Also since we don't disable EV_READ anymore we don't need some enable EV_READ, so we will reduce number of epoll_ctl() calls.

Azat Khuzhin 54c887d8 2014-11-12T20:23:46 http: use IP address that we got before (if any) during retrying Before this patch every time we are retrying our request we resolve domain, but we could optimize this (since UDP is slow) by using cached conn_address value, so do this.
Azat Khuzhin 8bb38425 2014-11-15T21:46:11 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.

Just in case, I've tried next tests: - mixing timeouts/retries - shutdown http server and return it back - slow dns server for first request - sleep before accept - hacking libevent sources to change the behaviour of http layer (so it will go into that function which I'm insterested in).

Azat Khuzhin 0c7f0405 2013-10-01T19:12:13 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

Nate Rosenblum 5eb17885 2013-09-03T14:46:47 Avoid racy bufferevent activation The evhttp_send_reply method invokes evhttp_write_buffer with a callback that may release the underlying request object and bufferevent upon completion. This cleanup callback is invoked by the underlying bufferevent's write callback. Improperly enabling write events before referencing the bufferevent could lead to use after free and memory corruption.

According to J.2 in the standard, in its big list of undefined behavior: "The behavior is undefined in the following circumstances: ... — Addition or subtraction of a pointer into, or just beyond, an array object and an integer type produces a result that does not point into, or just beyond, the same array object (6.5.6)." So we've got to fix rtrim to not do that. Also, make it unit tested, and give it an evutil_*_ name.

Nick Mathewson c0e425ab 2012-05-09T11:06:06 Restore our priority-inversion-prevention code with deferreds Back when deferred_cb stuff had its own queue, the queue was always executed, but we never ran more than 16 callbacks per iteration. That made for two problems: 1: Because deferred_cb stuff would always run, and had no priority, it could cause priority inversion. 2: It doesn't respect the max_dispatch_interval code. Then, when I refactored deferred_cb to be a special case of event_callback, that solved the above issues, but made for two more issues: 3: Because deferred_cb stuff would always get the default priority, it could could low-priority bufferevents to get too much priority. 4: With code like bufferevent_pair, it's easy to get into a situation where two deferreds keep adding one another, preventing the event loop from ever actually scanning for more events. This commit fixes the above by giving deferreds a better notion of priorities, and by limiting the number of deferreds that can be added to the _current_ loop iteration's active queues. (Extra deferreds are put into the active_later state.) That isn't an all-purpose priority inversion solution, of course: for that, you may need to mess around with max_dispatch_interval.

Nick Mathewson 68120d9b 2012-02-29T15:07:31 Convert event-config.h macros to avoid reserved identifiers C reserves all identifiers beginning with an underscore for system use. But we had been mangling our autoconf identifiers with the prefix "_EVENT_" to avoid conflict with other programs. Instead, we will now use the prefix "EVENT__". With any luck, the double-underscore will still hint "here be dragons" to anybody tempted to think that event-config.h is a stable api. This is an automatically generated patch. The script that produced it was made by running this script over config.h.in: ===== #!/usr/bin/perl -w # Run this on config.h.in use strict; my %macros = (); while (<>) { if (/^# *undef +([A-Za-z0-9_]+)/) { $macros{$1} = 1; } } print "#!/usr/bin/perl -w -i -p\n\n"; for my $k (sort keys %macros) { print "s/(?<![A-Za-z0-9_])_EVENT_$k(?![A-Za-z0-9_])/EVENT__$k/g;\n"; } == And the script that it generated was then run over all .c and .h files: #!/usr/bin/perl -w -i -p s/(?<![A-Za-z0-9_])_EVENT_DISABLE_DEBUG_MODE(?![A-Za-z0-9_])/EVENT__DISABLE_DEBUG_MODE/g;
