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

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

Updated copyright notices to include the year 2018.

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: Replace http_*_debug() with e_debug()

lib-http: client: Remove redundant debug logging checks

lib-http: client: Add support for event API

lib-http: Cleanup - Add name parameter to http_client_host_create()

global: timeout_remove(NULL) is a no-op

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

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

lib-http: client: host: Moved http_client_host_submit_request() function. This is a preparation for a subsequent change.

lib-http: client: host: Moved http_client_host_check_idle() function. This is a preparation for a subsequent change.

lib-http: client: Avoid direct access to host object members from queue.

lib-http: client: Simplified initiation of connection setup upon request submission.

lib-http: client: Created separate http_client_queue_get() function. Before, this was combined in http_client_queue_create() which caused a large code block to be indentet. Separating creation and obtaining the current instance makes the code cleaner.

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: Compiling fix to host->ips reallocation.

lib-http: Try to reuse memory for host->ips allocation. If the host already had an IP, most of the time ips_count doesn't change anymore.

lib-http: client: Only drop queued requests when a DNS lookup fails; not also the ones that are already in progress.

lib-http: client: Fixed race condition between DNS refresh lookup and a soft connection timeout. The refreshing DNS lookup cleared all the IPs, but the soft connection timeout (and maybe other code) still relied on them. Adding tests everywhere for host->ips_count == 0 is annoying, so I changed the DNS lookup code such that the stale IPs remain present while the DNS lookup is being performed. The pending lookup prevents new connections through http_client_host_refresh(), so this will not create potentially useless connections.

global: Replaced all instances of memset(p, 0, sizeof(*p)) with the new i_zero() macro. Used the following script: C_FILES=`git ls-files *.c` H_FILES=`git ls-files *.h` for F in "$C_FILES $H_FILES"; do echo "$F" perl -p -i -e 's/safe_memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero_safe(&$1)/g' $F perl -p -i -e 's/safe_memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero_safe($1)/g' $F perl -p -i -e 's/memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero(&$1)/g' $F perl -p -i -e 's/memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero($1)/g' $F done

lib-http: client: Destroy host and associated queue objects after no more requests remain and an idle timeout expires.

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: Improved handling of hosts with explicit IP address.

lib-http: Changed http_client_request_error to set request to NULL It's going to internally unreference it, so the caller should be aware of it also. I also changed request state check to be an assert, since I don't think there's any safe way this could work otherwise.

lib-http: Started using struct uri_host in struct http_url.

uri-util: Removed have_port and have_host_ip flags. Presence of port can be tested with port != 0. Presence of IP can be tested with ip->family != 0.

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

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/'

http-client: Added support for using an HTTP proxy running on a unix socket.

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>

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: 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-client: Improved handing of delayed request errors. Originally each request would have its own zero timeout, but now only one timeout is put in the host object.

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.

lib-http: Recent DNS change caused lib-http to access uninitialized memory.

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: Added support for creating CONNECT tunnels through HTTP.

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

lib-http: Fixed client connection and peer log labels to show proper IPv6 peers. The labels did not put IPv6 addresses in square brackets.

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

lib-http: Fixed tracking number of pending connections to host-port.

lib-http: Don't assert-crash in case of somewhat unexpected failing connections.

lib-http: Always try to connect to host's all IPs when connections fail. Previously this was done only when the new connections started from the first IP.

lib-http: When successfully connected to a peer, don't drop the peer's pending connections. They could have been intentionally created for other urgent requests.

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

lib-http: Fixed assert-crash when host had multiple IPs and first one had failed.

lib-http: http_client_deinit() calls any pending delayed failure callbacks.

lib-http: Prepare for TLS SNI support.

lib-http: Pass connect failures all the way to request callback's error string.

lib-http: Simplify error handling by delaying connect() failures.

lib-http: If http_client_request_submit() fails, don't immediately call the callback. This simplifies the caller's error handling since there is now only one error code path instead of two.

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: Pass DNS lookup error message to caller instead of logging it.

lib-http: Avoid hanging on urgent requests. Patch by Timo & Stephan. There are still some problems though, all urgent requests don't seem to get a new connection.

lib-http: If connection was refused to a host, retry again on next request. Instead of never retrying again for the host.

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: Fixed hang with failed DNS lookups
