c8baac90 2011-03-07 21:55:47 Followup for Tomash Brechko's http patch This patch makes bufferevent_disable_hard() non-public, and adds a comment about what it's for and why it's used.
5dc56628 2011-02-24 12:30:40 Workaround libevent bug https://sourceforge.net/tracker/index.php?func=detail&aid=3078187&group_id=50884&atid=461324 The problem is that bufferevent_disable() doesn't disable EV_WRITE when 'connecting' flag is set. However from evhttp_connection_reset() we want to disable EV_WRITE for sure (we are closing the socket next). So we add bufferevent_disable_hard(), which acts like bufferevent_disable(), but resets 'connecting' flag before the call to the actual handler. TODO: bufferevent_disable_hard() shouldn't be public, remove it from event2/bufferevent.h.

63a715e1 2011-02-21 23:25:13 Correctly detect and stop non-chunked http requests when the body is too long Based on analysis and code from Bas Verhoeven and from Constantine Verutin.
95060b54 2011-02-13 00:41:22 Make URI parser able to tolerate nonconformant URIs. If the EVHTTP_URI_NONCONFORMANT flag is passed in (which it is when parsing URIs we get over the wire), then we relax our checks a lot. Specifically, we do nothing to check for correct characters in the path, query, and fragment parts of such a URI. We could do much more here: we could relax our hostname requirements, deal with spaces differently/better, trap some errors but not others, etc. But this should solve the worst user-agent compatibility issues for now; the other issues can wait for a later release.

a12839b0 2010-11-29 14:25:33 Merge remote branch 'chrisd/http_fixes2'
aab8c38b 2010-11-05 11:17:07 Add evhttp server alias interface, correct flagging of proxy requests. evhttp needs to be mindful of all hostnames and addresses that clients use to contact the main server and vhosts to know the difference between proxy requests and non-proxy requests.
ec5c5aec 2010-11-23 20:31:28 Handle evhttp PUT/POST requests with an empty body When we call evhttp_get_bodylen() [when transfer-encoding isn't set], having req->ntoread == -1 means that we have no content-length. But a request with no content-length has no body! We were treating the absent content-length as meaning "read till closed", which only holds for replies, not requests. This patch also allows PATCH requests to have a body.

f5b391e2 2010-11-04 11:53:34 Tweak interface for allowed methods
75a73414 2010-11-04 11:25:35 Define enumerators for all HTTP methods, including PATCH from RFC5789 This patch defines enumerators for all HTTP methods that exist (including PATCH introduced in RFC 5789). It also makes them bit-masky (that's not a word, is it?), breaking binary- but not source-code compatibility. evhttp now stores a bitmask specifying for which methods requests to dispatch and which ones to reject with "405 Method Not Allowed". By default that's the ones we currently have (GET, POST, HEAD, PUT, DELETE), thereby keeping functional compatibility (besides the minor change that one of the other methods will now cause 405 instead of 400. But I believe that could even be considered a bug-fix). evhttp is extended by evhttp_set_allowed_methods() with which the user can change that bitmask. no regressions here and my test-app still works. Haven't yet actually tested any of the new methods. What's obviously missing here is the special logic for the methods: OPTIONS: We should be fine here - I believe our current dispatch logic should work fine. Some convenience functions would be fine though. TRACE: I'm pretty certain we should never dispatch this to the callbacks and simply implement the necessary functionality built-in. CONNECT: Pretty straight-forward to implement (and considering the framework in which we implement it very efficient too). Should probably go built-in. PATCH: Except for checking the RFC against our pre-dispatch logic (there just might be some "MUST not have Some-Header" lurking somewhere) there is nothing to be done here, this is completely up to the user. Nothing to do.

84a7053e 2010-10-26 21:33:22 Merge remote branch 'github/20_http_read_after_write'
a4063c06 2010-10-26 10:38:30 Note that 2.0.9 will break the ABI, and make changes we were postponing. We had to turn a couple of 32-bit size arguments into 64-bit arguments or size_t arguments (since otherwise we would have had to do it post 2.0.x-stable, and that would be worse).
74c0e862 2010-10-25 21:53:15 Avoid missed-request bug when entire http request arrives before data is flushed The trigger for starting to read the first line of a request used to be, "When data has arrived and we're looking for the first line." But that's not good enough: if the entire next request gets read into our bufev->inbuf while we're still processing the current request, we'll never see any more data arrive, and so will never process it. So the fix is to make sure that whenever we hit evhttp_send_done, we call evhttp_read_cb. We can't call it directly, though, since evhttp_send_done is reachable from the user API, and evhttp_read_cb can invoke user functions, and we don't want to force everyone to have reentrant callbacks. So, we use a deferred_cb. Found by Ivan Andropov. This is bug 3008344.
8e342e56 2010-10-25 16:09:11 Correctly count req->body_size on http usage without Content-Length There was a dumb bug where we would look at the length of the input buffer immediately _after_ we drained it.
58a1cc6b 2010-10-25 16:00:47 Fix a bug where we would read too much data in HTTP bodies or requests. We were using evbuffer_add_buffer, which moved the entire buffer contents. But if we had a valid content_length, we only wanted to move up to the amount of data remaining in ntoread. Our bug would make us put our ntoread in the negative, which would in turn make us read all data until the connection closed. Found by Denis Bilenko. Should fix bug 2963172.
525da3e1 2010-10-25 15:49:42 Fix Content-Length when trying send more than 100GB of data (!) on an evhttp.

cd00079b 2010-10-21 12:19:28 Add evhttp_connection_get_base() to get the event_base from an http connection Based on a patch by Mark Ellzey from 27 July 2010. Closes ticket 3052406
2075fbcf 2010-10-19 13:15:48 Add evhttp_parse_query_str to be used with evhttp_uri_parse. The old evhttp_parse_query() doesn't work well with struct evhttp_uri.query, since it expects to get whole URIs, rather than just the query portion.

86dd720a 2010-08-08 16:46:39 Introduce absolute URI parsing helpers. See evhttp_uri_parse(), evhttp_uri_free() and evhttp_uri_join() for details.
49f4bf7c 2010-10-18 13:58:02 Add evhttp_request_get_command so code can tell GET from POST without peeking at the struct.
a8148ced 2010-10-08 13:05:13 New evhttp_uri(encode|decode) functions to handle + and NUL characters right The old evhttp_decode_uri() function would act as tough it was doing an (illegal, undefined) decode operation on a whole URL at once, and treat + characters following a ? as different from + characters preceding one. But that's not useful: If you are decoding a URI before splitting off query parameters, you are begging to fail as soon as somebody gives you a value with an encoded & in it. The new evhttp_uridecode() function takes an argument that says whether to decode + signs. Both uridecode and uriencode also now support encoding or decoding to strings with internal 0-valued characters.
2e63a604 2010-10-08 12:57:11 evhttp_encode_uri encodes all reserved characters, including !$'()*+,/:=@ Perviously, some characters not listed as "unreserved" by RFC 3986 (notably "!$'()*+,/:=@") were not encoded by evhttp_encode_uri. This made trouble, especially when encoding path components (where @ and / are bad news) and parameters (where + should get encoded so it doesn't later decode into a space). Spotted by Bas Verhoeven.

b1756d01 2010-10-06 11:48:52 Let evhttp_parse_query return -1 on failure We already detected certain malformed queries, but we responded by aborting the query-parsing process half-way through without telling the user. Now, if query-parsing fails, no headers are returned, and evhttp_parse_query returns -1.

9c8db0f8 2010-09-23 22:45:55 Fix all warnings in the main codebase flagged by -Wsigned-compare Remember, the code int is_less_than(int a, unsigned b) { return a < b; } is buggy, since the C integer promotion rules basically turn it into int is_less_than(int a, unsigned b) { return ((unsigned)a) < b; } and we really want something closer to int is_less_than(int a, unsigned b) { return a < 0 || ((unsigned)a) < b; } . Suggested by an example from Ralph Castain
90b3ed5b 2010-08-09 13:25:50 Add some comments to http.c and make a few functions static.
ec347b92 2010-07-07 16:45:03 Move event-config.h to include/event2 This change means that all required include files are in event2, and all files not in event2/* are optional.
29b2e233 2010-05-30 03:17:48 Fix possible nullptr dereference in evhttp_send_reply_end() (The existing implementation had sanity-checking code for the case where its argument was NULL, but it erroneously dereferenced it before actually doing the sanity-check. --nickm)
39906698 2010-05-26 12:58:02 Let evhttp_send_error infer the right error reasons
06bd0563 2010-05-26 12:50:59 Fix the default HTTP error template The current template... <HTML><HEAD><TITLE>%s</TITLE> </HEAD><BODY> <H1>Method Not Implemented</H1> Invalid method in request<P> </BODY></HTML> is highly confusing. The given title is easily overlooked and the hard-coded content is just plain wrong in most cases (I really read this as "the server did not understand the requested HTTP method) This patch changes the template to include the error reason in the body as well as in the header, and to infer the proper reason from the status code whenever the reason argument is NULL. This patch also removes a redundant evhttp_add_header from evhttp_send_error; evhttp_send_page already adds a "Connection: close" header.
caca2f45 2010-05-14 14:36:49 Replace (safe) use of strcpy with memcpy to appease OpenBSD If Libevent uses strcpy, even safely, it seems OpenBSD's linker will complain every time a library links Libevent. It's easier just not to use the old thing, even when it's safe to do so.
c1cd32a1 2010-05-08 22:21:52 Define _REENTRANT as needed on Solaris, elsewhere It turns out that _REENTRANT isn't only needed to make certain functions visible; we also need it to make pthreads work properly some places (like Solaris, where forgetting _REENTRANT basically means that all threads are sharing the same errno). Fortunately, our ACX_PTHREAD() configure macro already gives us a PTHREAD_CFLAG variable, so all we have to do is use it.

899c1dcc 2010-04-14 15:42:57 Replace EVUTIL_CLOSESOCKET macro with a function The EVUTIL_CLOSESOCKET() macro required you to include unistd.h in your source for POSIX. We might as well turn it into a function: an extra function call is going to be cheap in comparison with the system call. We retain the EVUTIL_CLOSESOCKET() macro as an alias for the new evutil_closesocket() function. (commit message from email by Nick and Sebastian)

c7cf6f00 2010-03-05 12:47:46 Replace users of "int fd" with "evutil_socket_t fd" in portable code Remeber, win32 has a socket type that's actually a handle, so if there's a chance that code is run on win32, we can't use "int" as the socket type. This isn't a blind search-and-replace: sometimes an fd is really in fact for a file, and not a socket at all.

93d73691 2010-02-03 14:34:56 do not fail while sending on http connections the client closed. when sending chunked requests via multiple calls to evhttp_send_reply_chunk, the client may close the connection before the server is done sending. this used to cause a crash. we introduce a new function evhttp_request_get_connection() that allows the server to determine if the request is still associated with a connection. If it's not, evhttp_request_free() needs to be called explicitly or the user can call evhttp_send_reply_end() which just frees the request, too.

ff3f6cd4 2010-01-22 16:14:49 Check more internal event_add() calls for failure Most of these should be unable to fail, since adding a timeout generally always works. Still, it's better not to try to be "too smart for our own good here." There are some remaining event_add() calls that I didn't add checks for; I've marked those with "XXXX" comments.
5032e526 2010-01-14 15:42:07 do not use a function to assign the evdns base; instead assign it via evhttp_connection_base_new() which is a new function introduced in 2.0
ec34533a 2009-12-30 00:41:03 Make http use evconnlistener. Now that we have a generic listen-on-a-socket mechanism, there's no longer any reason to have a separate listen-on-a-socket implementation in http.c. This also lets us use IOCP and AcceptEx() when they're enabled. Possibly, we should have a new mechanism to add a socket given only a listener.
c698b77d 2009-12-30 00:11:27 Allow http connections to use evdns for hostname looksups. This was as simple as using bufferevent_connect_hostname instead of calling connect() ourself, which already knows how to use an evdns_base if it gets one. Untangling the bind code might be a little trickier.
