lib-ssl-iostream: ostream-openssl: Fix behavior of o_stream_flush() so that 1 is only returned when buffer is empty.

lib-ssl-iostream: ostream-openssl: Create local variable for sstream->ssl_io->plain_output in o_stream_ssl_flush().

lib: ostream: Allow switching to a specific ioloop.

Updated copyright notices to include the year 2018.

iostream-openssl: Refactor stream sync code When doing input or stream sync, specify the type of operation that we are doing to make sure we do IO correctly.

global: Fix spelling mistakes in comments Original work by @andreasschulze and @jsoref

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

Updated copyright notices to include the year 2017.

global: Use buffer_get_writable_size() where possible With 09539f3db increasing buffer's init_size with +1 some fts-icu unit tests started failing. And in general it's better to use the writable size since that provides the true size that can be used.

lib-ssl-iostream: Implement get_used_size() method. Previously we were always returning that we didn't have anything buffered, which could have caused huge memory usage (or malloc failures) with its users (e.g. dsync).

iostreams: Set stream error string when it provides extra information.

iostream-ssl: Don't hang if ostream's max buffer size is set to 0.

iostreams: Added close_parent flag to close() handler and clarified close/destroy APIs. This makes it unambiguous how things work: Unless you explicitly call [io]_stream_close(), the parent streams won't be closed. This is what most (hopefully all!) of the existing code expects. I was wondering a bit if [io]_stream_destroy() should simply have been removed and replaced with [io]_stream_unref() calls, since they would have worked basically everywhere, but there might be some places where it's better to have explicitly closed the stream (and where closing the parent stream doesn't matter).

lib-ssl-iostream: Fixed "bad write retry" errors when output had to be buffered.

Oops :) Update copyrights to 2013 without breaking all .c files.

Updated copyright notices to include year 2013.

lib-ssl-iostream now dynamically loads openssl library instead of linking to it. This allowed removing the separate libdovecot-ssl library. In future if GnuTLS/NSS support is added it would also allow switching between them dynamically.

Added o_stream_get_fd().
