global: drop unnecessary parens in &(foo) This makes the code more consistent since most of the repo uses the no-parens style. These inconsistencies were found using `git grep '(&([^*]'` and any use of the parens in macros was ignored for safety reasons.

global: Use t_buffer_create sed -i -e 's/buffer_create_dynamic(pool_datastack_create(), */t_buffer_create(/g'

global: Use i_stream_read_memarea() wherever possible

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-dcrypt: Use cpu32_to_be instead of htonl prefer our own conversion functions over htonl which is intended for networking related numbers.

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);

global: use new byte ordering API

lib-dcrypt: istream-decrypt - set stream_errno=EPIPE on unexpected EOF

Updated copyright notices to include the year 2017.

lib-dcrypt: Add error handling for dcrypt_key_id_private

global: Added missing copyright notices.

lib-dcrypt: Avoid infinite loop if istream header is too large. We'll return an error now instead. We can't just return -2 here, because nothing was actually being returned to the caller. Attempting to do that would just trigger an assert: Panic: file istream.c: line 182 (i_stream_read): assertion failed: (_stream->skip != _stream->pos)

dcrypt: Allow stream prefetch We might get stream that has already been buffered, so we must try read it in case buffer is full.

lib-dcrypt: Fixed accessing out-of-bounds data in istream. Also some small cleanups to make it clearer what's actually happening.

lib-dcrypt: Fixed partial reads in header and limit header's max size. Also fixes test-stream to actually test nonblocking reads correctly.

lib-dcrypt: make decrypt_istream format and flags visible

lib-dcrypt: add dcrypt-iostream.h Move everything from dcrypt-iostream-private.h and enum io_stream_encrypt_flags to the new dcrypt-iostream.h file.

lib-dcrypt: Support nonblocking istreams.

istream-decrypt: Fix error handling in stream header

lib-dcrypt: Handle short reads in header correctly

dcrypt-iostream: Ref/unref keys

lib-dcrypt: Improved error message when istream isn't encrypted.

lib-dcrypt: istream-decrypt now differentiates between temporary errors and corruption.

lib-dcrypt: Set stream_errno on istream-decrypt read failures. Fixes assert-crashes that would happen otherwise.

dcrypt: Fix bugs in 0 and 1 byte payload files

istream-decrypt: Correctly check the header length for v1

lib-dcrypt: Use hex encoded public key ID in callback

lib-dcrypt: Use dcrypt_key_id_private when applicable

lib-dcrypt: Finish previous t_malloc() change.

lib-dcrypt: Initial implementation
