31 * Revision 2.0 2002/06/04 14:34:21 jongfoster
32 * Moving source files to src/
34 * Revision 1.9 2002/03/26 22:29:54 swa
35 * we have a new homepage!
37 * Revision 1.8 2002/03/25 19:32:15 joergs
38 * Name in version string changed from junkbuster to Privoxy.
40 * Revision 1.7 2002/03/24 13:25:43 swa
41 * name change related issues
43 * Revision 1.6 2002/03/09 20:03:52 jongfoster
44 * - Making various functions return int rather than size_t.
45 * (Undoing a recent change). Since size_t is unsigned on
46 * Windows, functions like read_socket that return -1 on
47 * error cannot return a size_t.
49 * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
50 * crashes, and also frequently caused JB to jump to 100%
51 * CPU and stay there. (Because it thought it had just
52 * read ((unsigned)-1) == 4Gb of data...)
54 * - The signature of write_socket has changed, it now simply
55 * returns success=0/failure=nonzero.
57 * - Trying to get rid of a few warnings --with-debug on
58 * Windows, I've introduced a new type "jb_socket". This is
59 * used for the socket file descriptors. On Windows, this
60 * is SOCKET (a typedef for unsigned). Everywhere else, it's
61 * an int. The error value can't be -1 any more, so it's
62 * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
63 * Windows it maps to the #define INVALID_SOCKET.)
65 * - The signature of bind_port has changed.
67 * Revision 1.5 2002/03/03 09:18:03 joergs
68 * Made jumbjuster work on AmigaOS again.
70 * Revision 1.4 2001/10/07 15:35:13 oes
71 * Replaced 6 boolean members of csp with one bitmap (csp->flags)
73 * Revision 1.3 2001/09/12 22:54:51 joergs
74 * Stacksize of main thread increased.
76 * Revision 1.2 2001/05/23 00:13:58 joergs
77 * AmigaOS support fixed.
79 * Revision 1.1.1.1 2001/05/15 13:58:46 oes
80 * Initial import of version 2.9.3 source tree
