lib-http: Create http-common.h, which contains global definitions shared by client and server. Currently contains only the default HTTP port definitions that used to be private to the client.

lib-http: client: Make sure all ioloop objects are created on the ioloop that the client/context is switched to.

lib-http: client: Implicitly switch ioloop for global shared client context. If the new ioloop is NULL, close the shared client context. In that case all shared hosts, peers and idle connetions are closed and destroyed. The context just remains as a container for settings and shared context. This is only allowed when there are no clients left.

lib-http: client: Use merged DNS settings from all clients connected to a shared context for DNS lookups.

lib-http: client: Base forcing shared context debug logging on the settings of the context itself and each associated client.

lib-http: client: Register client objects in the associated client shared context.

lib-http: client: Call switching ioloop for shared peer from shared client context. Before, it was called from the client peer.

lib-http: client: Merge socket buffer size settings with settings from shared context. While using the default global context, per-client socket buffer size settings were ignored.

lib-http: client: Merge max_idle_time_msecs setting with setting from shared context. While using the default global context, per-client max_idle_time_msecs setting was ignored.

Updated copyright notices to include the year 2018.

lib-http: Add http_client_init_private() This allows creating a HTTP client without a shared context, in case it's needed for some reason.

lib-http: Change http_client_init() to use the global shared client context This is most likely what is usually wanted.

lib-http: Add http_client_get_global_context()

lib-http: client: Check whether client is running in a wait loop with the correct condition. This used to check client->ioloop != NULL, but now it should check client->waiting. Previous commit (e8a1b62fe4a81b211dcccd1a58b44f254074eab6) omitted a few instances where this should have been changed.

lib-http: client: Made http_client record the current ioloop it is switched to. This prevents http_client_wait() from switching the client to an ioloop it was never explicitly switched to.

lib-http: client: Replace http_*_debug() with e_debug()

lib-http: client: Remove redundant debug logging checks

lib-http: client: Add support for event API

lib-http: client: Cleaned up initialization of client settings. There were checks for the client context not being NULL, which makes no sense anymore, since a private context is always created when none is provided. Problem reported by Coverity.

lib-http: client: Amended the top comment explaining the structure of the HTTP client.

lib-http: client: Added identifier to client log messages.

lib-http: client: shared context: Allow sharing peer state between clients.

lib-http: client: shared context: Allow sharing host lookups between clients.

lib-http: client: Moved connection list from client to shared context.

lib-http: client: Created basic shared context between clients. In this basic form it only shares default settings.

lib-http: client: Fixed whitespace in the top comment explaining the structure of the HTTP client.

global: Replace ssl_iostream_context_init_client() with ssl_iostream_client_context_cache_get()

global: Rename ssl_iostream_context_deinit() to ssl_iostream_context_unref()

global: start relying on timeout_remove(NULL) being a no-op Cleanup performed with the following semantic patch: @@ expression E; @@ - if (E != NULL) { - timeout_remove(&E); - } + timeout_remove(&E);

lib-http: client: Restructured the handling of delayed errors. The req->delayed_error* fields are cleared before the callback is called and before the request is dereferenced. This way, freeing the request never removes it from the delayed request list when the list is being processed. It also makes it possible to resubmit the request from the callback (mainly for future use).

Updated copyright notices to include the year 2017.

lib-http: client: Implemented host name lookup TTL. Host name lookups will now be performed again when the results have expired. Without access to TTL information from DNS lookups, all lookups will use the same default TTL for now.

lib-http: client: Implemented no_auto_retry setting that disables all automatic request retries. This currently only applies to requests sent over a connection that is subsequently lost before a response is received. Before, such requests were always implicitly resumbitted for a new connection, without the application knowing about it. By enabling the no_auto_retry client setting, the application is always notified of connection loss through the request's response callback. As a consequence, requests need to be retried explicitly using the http_client_request_try_retry().

lib-http: client: Prevent useless and unexpected request callbacks during http_client_deinit(). Requests are now destroyed before queues, hosts, peers and connections. As a side-effect, requests are now removed from the client request list at http_client_request_destroy(), so that requests with lingering references will no longer make http_client_wait() hang.

lib-http: client: Added settings to configure the connection's socket kernel buffer sizes. This is mainly useful for use in the lib-http test suite.

lib-http: client: Made peer object reference-counted to prevent invalid memory access in request handling routine. Resetting the peer->handling_requests flag risked triggering a segfault, since the peer object could be deleted from within the request handler loop.

lib-http: Allow http_client_settings.ssl==NULL

lib-http: use ssl_iostream_settings in http_client_settings

lib-http: client: Gave request, connect and dns timeouts defaults that make more sense.

lib-http: Always set *_obj=NULL first in deinit functions (mainly for consistency) This doesn't usually matter, but in case deinit calls some callback they may be trying to access the partially destroyed object.

lib-http client: Implemented proxy authentication using Basic scheme.

lib-http: client: Implemented maximum for connection backoff time. Without a maximum, the backoff time grows exponentially to enormous values, because it isn't reset until the connection succeeds. This causes recovery from connection failures to become very slow. Current maximum is one minute.

lib-http: client: Created list of all submitted requests. Currently only needed to improve debugging of hanging requests.

lib-http: client: Moved delayed failed requests from host to client object.

lib-http: client: Added support for absolute request timeout. Requests cannot survive beyond this deadline.

lib-http: client: Implemented support for connection failure backoff.

lib-http: client: Added support for attempting a single IP several times. Also limits the number of attempts when there are many IPs.

lib-http: Updated comments to RFC7230/RFC7231.

lib-http: Fixed resource leaks in http_client_wait() occurring a dns_client is used. If all DNS lookups finished before the end of the wait cycle, the dns_client would not be switched back to the original ioloop.

Updated copyright notices to include year 2014.

http: Implemented delayed requests scheduling. Requests can now be (re)submitted with a delay. The request is not sent until the delay time expires. This facilitates handling the Retry-After header in responses. This can either be performed automatically if the indicated delay is not too long or explicitly by the code using lib-http.

http-client: Changed struct http_client_host_port into a struct http_client_queue object. Peer and request objects now reference the queue object directly rather than the host object. This way, there is no need to find the matching host:port in the host anymore. This makes the queueing structure more intuitive and more efficient. This is a first step towards support for connecting to HTTP services through unix sockets or directing requests at specific hosts (so not from the URL). This patch also fixes a potential timeout leak (to_connect) in http_client_host_port (now http_client_queue) and makes sure it is moved during switch_ioloop(). Finally it updates the structure comment at the top of http-client.c.

Use io_loop_set_current() instead of directly setting it.

lib-http: Support DNS lookups via the new dns-client API.

lib-http: http-client: Added support for tunneling SSL conntections through proxy.

lib-http: http-client: Implemented proxy support.

lib-http: Added support for disabling automatic redirects.

lib-http: Added setting for User-Agent header.

lib-http: Implemented limits on overall HTTP header size, size of individual header fields and the number of fields in the header.

lib-http: http-client: Fixed request scheduling and connection management.

lib-http: Added http_client_get_pending_request_count()

lib-http: Added soft_connect_timeout_msecs setting to connect to multiple IPs in parallel. Based on patch by Stephan Bosch.

lib-http: Added connect and request timeout settings.

lib-http: Added ssl_cert|key|key_password settings to be passed to ssl-iostream. These are used for sending client's SSL certificate.

Added ssl_client_ca_file to specify the CA certs as a file instead of as a dir. This is required for Redhat-based systems where there isn't a CA directory like in Debian/Ubuntu.

lib-http: ssl_crypto_device and ssl_allow_invalid_cert settings were ignored.

lib-http: Fixed moving delayed request error timeouts between ioloops.

lib-ssl: If debug=TRUE, set also SSL verbose=TRUE

lib-ssl-iostream: API changes to return error strings if init() functions fail. This also fixed a couple of broken error handlings.

lib-http: Each peer doesn't need a separate ssl context, enough to have one for http_client. Also removed #ifdefs for building with SSL support. lib-ssl-iostream nowadays dynamically loads the SSL library when needed, and also handles failures if Dovecot was built without SSL support.

lib-http: Added ssl_ca setting to specify the CA certificate directly.

lib-http: Fixed http_client_wait() assert.

lib-http: Track peers using a linked list also. Mainly because this makes it much easier to debug using gdb. The overhead isn't that much extra either.

lib-http: Assert-crash in http_client_wait() if it's waiting without doing anything.

lib-http: Track list of hosts using a linked list also. http_client_switch_ioloop() is done very often, and scanning a few entries in a linked list is much faster than going through a hash table.

lib-http: Avoid hanging in http_client_wait() while there's nothing to do.
