What's New In Libevent SVN:
|
|
|
|
0. About this document
|
|
|
|
This document describes the key differences between Libevent 1.4 and
|
|
Libevent ???, from a user's point of view. It was most recently
|
|
updated based on features in subversion trunk as of 27 Dec 2007.
|
|
|
|
NOTE 1: As of this writing, we haven't decided whether the trunk
|
|
version of svn will turn into a 1.5 or 2.0.
|
|
|
|
NOTE 2: If any features or fixes get backported from trunk to 1.4,
|
|
they should get moved from here into whatsnew-14.txt, since they
|
|
will no longer be differences between 1.4 and this version.
|
|
|
|
1. Packaging Issues.
|
|
|
|
2. New and Improved APIs
|
|
|
|
2.1. Overrideable allocation functions
|
|
|
|
If you want to override the allocation functions used by libevent
|
|
(for example, to use a specialized allocator, or debug memory
|
|
issues, or so on), you can replace them by calling
|
|
event_set_mem_functions. It takes replacements for malloc(),
|
|
free(), and realloc().
|
|
|
|
2.2. More flexible readline support
|
|
|
|
The old evbuffer_readline() function (which accepted any sequence of
|
|
CR and LF characters as a newline, and which couldn't handle lines
|
|
containing NUL characters), is now deprecated. The preferred
|
|
function is evbuffer_readln(), which supports a variety of
|
|
line-ending styles, and which can return the number of characters in
|
|
the line returned.
|
|
|
|
2.3. Socket is now an abstract type
|
|
|
|
All APIs that formerly accepted int as a socket type now accept
|
|
"evutil_socket_t". On Unix, this is just an alias for "int" as
|
|
before. On Windows, however, it's an alias for SOCKET, which can
|
|
be wider than int on 64-bit platforms.
|
|
|
|
3. Big bugfixes
|
|
|
|
4. Big performance improvements

|

5. Removed code and features
