lib: istream: Allow switching to a specific ioloop.

Updated copyright notices to include the year 2018.

global: Add flags parameter to i_stream_create() and set it to 0 This just changes the API - the following changes add the new flag.

lib: iostream-pump - Specify what failed in completion callback parameter This makes it easier for the caller to find out whether the failure was due to istream or ostream.

global: Rename i_stream_is_eof() to i_stream_read_eof() This describes its behavior a bit better.

lib-http: server: Implemented http_server_request_fail_text(), which allows creating failure responses with verbose payload.

lib-http: server: Allow determining at any time whether the connection will be closed after handling a request. Previously, this was only possible during response submission, which potentially requires making a `close' parameter available for any API function that submits a (failure) response. This would become very ugly and inflexible.

lib-http: server: Make sure broken connection input always causes the connection to be closed after response.

lib-http: server: Implemented API for handling the incoming request payload in the background. It allows forwarding the incoming payload to an output stream (e.g. iostream-temp) or to a buffer. The maximum size of the payload is configurable. The client will get a 413 error if the maximum is exceeded.

lib-http: server: Changed http_server_request_is_complete() from an inline to a normal function.

lib-http: Improve http_server_request_set_destroy_callback API It now allows using non-void* context

lib-http: server: Do not generate a payload for a failure response for a HEAD request.

Updated copyright notices to include the year 2017.

global: Require comparisons to be strict boolean expressions * No implicit integer -> boolean or pointer -> boolean conversions * !expr can be used only if expr is boolean type These were checked with a patched clang. It found various actual bugs, which were fixed by the previous commits.

lib-http, lib-mail, lib-storage: parent unrefs Remove some unneccesary parent unrefs from i_stream_*_destroys. Don't know too many or too few were removed.

lib-http: server: Prevent aborting finished or already aborted requests again.

lib-http: server: Fixed handling of partially read request payload. This would sometimes cause the server to hang.

lib-http: http_server_request_unref() now always sets *req=NULL This makes its behavior consistent with other APIs in Dovecot.

lib-http: server: Error handling fix - avoid potential crash when request is already gone

lib-http: server: Implemented blocking request input stream.

lib-http: server: Created blocking http_server_response_send_payload() API that closely mimics the client equivalent. It allows sending response payload in several chunks in a blocking fashion.

lib-http: server: Added some request debug logging.

global: freshen copyright git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-5]/$1-2016/g;s/ (201[0-5]) Dovecot/ $1-2016 Dovecot/'

lib-http: Added asserts to all refcount increments. These could catch situations where an already freed object's refcount is attempted to be increased.

global: freshen copyright Robomatically: git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-4]/$1-2015/g;s/ (201[0-4]) Dovecot/ $1-2015 Dovecot/' Happy 2015 everyone! Signed-off-by: Phil Carmody <phil@dovecot.fi>

Mark more memory pools as growing

lib-http: server: Fixed connection reference counting. Connection often still got destroyed too early. Particularly submitting responses would potentially destroy the connection, which is often unexpected. Sending responses is now postponed until handled by the stream output handler, which is explicitly triggered when necessary.

lib-http: server: Added support for authentication.

lib-http: server: Made sure destroy callback is called only once.

lib-http: server_request/connection - improve encapsulation It just feels a bit dirty having the request mess around with the connection's internals, have the connection manage its linked lists itself. No functional changes. Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib-http server: Delay calling the request's destroy callback until handle_request() callback is finished. This simplifies the code in the handle_request() so it doesn't need to keep track of whether the response is already submitted or not.

lib-http server: Added http_server_request_is_finished() This is intended mainly to be used in asserts and such checks.

lib-http: Call the destroy callback also when request is aborted.

lib-http server: Call request destroy callback immediately after response is finished sending. Regardless of any other references to the request.

lib-http: server: Fixed server waiting for payload of already failed request.

lib-http server: Made http_server_request_[un]ref() public. Also http_server_request_unref() now returns if this was the last reference or not.

lib-http server: Added http_server_request_get_response() Also make sure that only a single response can be created for a request.

lib-http server: Removed "bool close" parameters in favor of _close() functions. Most callers don't want to close the connection so it's an extra parameter usually. Also it's difficult to remember what the TRUE/FALSE means so it's easy to cause bugs by copy&pasting the code. http_server_request_fail() will also now forcibly close the connection if conn->input_broken is set.

lib-http: Added initial support for server-side HTTP API.
