global: Change string position/length from unsigned int to size_t Mainly to avoid truncating >4GB strings, which might potentially cause some security holes. Normally there are other limits, which prevent such excessive strings from being created in the first place. I'm sure this didn't find everything. Maybe everything could be found with compiler warnings. -Wconversion kind of does it, but it gives way too many unnecessary warnings. These were mainly found with: grep " = strlen" egrep "unsigned int.*(size|len)"

global: Replaced all i_stream_read_data() with _more() and _bytes()

lib: istream - more migration to i_stream_read_bytes() This time a coccinelle semantic patch, again hand checked: git grep 'i_stream_read_data' | sed s/:.*// | \ while read f; do spatch --sp-file istream.cocci --in-place "$f" ; done -- 8< --- istream.cocci --- @@ expression e1, e2, e3, e4; @@ - i_stream_read_data(e1, e2, e3, e4 - 1) + i_stream_read_bytes(e1, e2, e3, e4) -- 8< --- end Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib: istream - migrate to i_stream_read_bytes() Scripted to pick off the low hanging fruit, one liners with an explicit '-1' in the final parameter, but hand-checked. git grep 'i_stream_read_data.*, [^,]*- \?1)' | sed s/:.*// | \ xargs sed -i -e 's/i_stream_read_data(\(.*\), \(.*\), \(.*\), \(.*[^ ]\) \?- \?1)/i_stream_read_bytes(\1, \2, \3, \4)/' Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib-compress: lz4 istream wasn't detected reliably in some situations. We requested too few bytes from istream, so there wasn't any guarantee that the istream actually had all the bytes. This caused a problem for example with mdbox when the previous mail was already fetched and the stream happened to end in the middle of the lz4 header.

Updated copyright notices to include year 2014.

lib-compression: Added initial support for LZ4 There's no standard file format for LZ4, so we created our own. The code has had only minimal testing currently, so there may be bugs.

lib-compression: Added support for liblzma (xz) Annoyingly this is mainly copy&pasted [io]stream-bzlib, but I'm not sure if it's worth the effort to try to create common functions for them.

Fixed compiling without zlib.

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

Moved zlib/bzlib code to lib-compression library.
