* Purpose : Contains wrappers for system-specific sockets code,
|
|||
|
|
* so that the rest of Junkbuster can be more
|
|||
|
|
* OS-independent. Contains #ifdefs to make this work
|
|||
|
|
* on many platforms.

* Revision 1.14 2008/12/20 14:53:55 fabiankeil
|
|||
|
|
* Add config option socket-timeout to control the time
|
|||
|
|
* Privoxy waits for data to arrive on a socket. Useful
|
|||
|
|
* in case of stale ssh tunnels or when fuzz-testing.

|
* Revision 1.13 2008/03/21 11:13:59 fabiankeil
|
|||
|
|
* Only gather host information if it's actually needed.
|
|||
|
|
* Also move the code out of accept_connection() so it's less likely
|
|||
|
|
* to delay other incoming connections if the host is misconfigured.

|
|
* Revision 1.5 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 1.4 2002/03/07 03:51:36 oes

|||

|
* - Improved handling of failed DNS lookups
