31 * Revision 1.11 2006/07/18 14:48:45 david__schmidt
32 * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
33 * with what was really the latest development (the v_3_0_branch branch)
35 * Revision 1.9 2002/03/26 22:29:54 swa
36 * we have a new homepage!
38 * Revision 1.8 2002/03/25 19:32:15 joergs
39 * Name in version string changed from junkbuster to Privoxy.
41 * Revision 1.7 2002/03/24 13:25:43 swa
42 * name change related issues
44 * Revision 1.6 2002/03/09 20:03:52 jongfoster
45 * - Making various functions return int rather than size_t.
46 * (Undoing a recent change). Since size_t is unsigned on
47 * Windows, functions like read_socket that return -1 on
48 * error cannot return a size_t.
50 * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
51 * crashes, and also frequently caused JB to jump to 100%
52 * CPU and stay there. (Because it thought it had just
53 * read ((unsigned)-1) == 4Gb of data...)
55 * - The signature of write_socket has changed, it now simply
56 * returns success=0/failure=nonzero.
58 * - Trying to get rid of a few warnings --with-debug on
59 * Windows, I've introduced a new type "jb_socket". This is
60 * used for the socket file descriptors. On Windows, this
61 * is SOCKET (a typedef for unsigned). Everywhere else, it's
62 * an int. The error value can't be -1 any more, so it's
63 * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
64 * Windows it maps to the #define INVALID_SOCKET.)
66 * - The signature of bind_port has changed.
68 * Revision 1.5 2002/03/03 09:18:03 joergs
69 * Made jumbjuster work on AmigaOS again.
71 * Revision 1.4 2001/10/07 15:35:13 oes
72 * Replaced 6 boolean members of csp with one bitmap (csp->flags)
74 * Revision 1.3 2001/09/12 22:54:51 joergs
75 * Stacksize of main thread increased.
77 * Revision 1.2 2001/05/23 00:13:58 joergs
78 * AmigaOS support fixed.
80 * Revision 1.1.1.1 2001/05/15 13:58:46 oes
81 * Initial import of version 2.9.3 source tree
