+ * Revision 1.14 2009/05/13 18:20:54 fabiankeil
+ * There's no reason for keep_alive_timeout to be signed.
+ *
+ * Revision 1.13 2009/05/10 10:12:30 fabiankeil
+ * Initial keep-alive support for the client socket.
+ * Temporarily disable the server-side-only keep-alive code.
+ *
+ * Revision 1.12 2008/12/24 17:06:19 fabiankeil
+ * Keep a thread around to timeout alive connections
+ * even if no new requests are coming in.
+ *
+ * Revision 1.11 2008/11/13 09:08:42 fabiankeil
+ * Add new config option: keep-alive-timeout.
+ *
+ * Revision 1.10 2008/10/09 18:21:41 fabiankeil
+ * Flush work-in-progress changes to keep outgoing connections
+ * alive where possible. Incomplete and mostly #ifdef'd out.
+ *
+ * Revision 1.9 2006/07/18 14:48:46 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)

+ * Revision 1.4 2002/03/09 20:03:52 jongfoster
+ * - Making various functions return int rather than size_t.
+ * (Undoing a recent change). Since size_t is unsigned on
+ * Windows, functions like read_socket that return -1 on
+ * error cannot return a size_t.
+ *
+ * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ * crashes, and also frequently caused JB to jump to 100%
+ * CPU and stay there. (Because it thought it had just
+ * read ((unsigned)-1) == 4Gb of data...)
+ *
+ * - The signature of write_socket has changed, it now simply
+ * returns success=0/failure=nonzero.
+ *
+ * - Trying to get rid of a few warnings --with-debug on
+ * Windows, I've introduced a new type "jb_socket". This is
+ * used for the socket file descriptors. On Windows, this
+ * is SOCKET (a typedef for unsigned). Everywhere else, it's
+ * an int. The error value can't be -1 any more, so it's
+ * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ * Windows it maps to the #define INVALID_SOCKET.)
+ *
+ * - The signature of bind_port has changed.
+ *
* Revision 1.3 2001/07/29 18:58:15 jongfoster
* Removing nested #includes, adding forward declarations for needed
* structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
