523f2003fa Removed the DNS API calls and replaced them with the standard 
gethostbyname() and gethostbyaddr() functions.  This is possible
because tinyproxy now uses a standard pre-forked() method.

a34db10d65 Fixed some spelling mistakes, and removed the getpeer_ip() and 
getpeer_string() functions as they've been replaced by the
getpeer_information() function.

478030c6ff Changed the lookup_domain() function to use the new "dnsserver" API. 
Also moved safe_write(), safe_read(), readline(), and write_message()
functions into their own file.

d7c3f23610 bind_address has been moved inside the config structure. Fixed up a 
problem where "data" was being freed even if it had not been allocated
(because of an error condition.)

08077cc9e1 The "Bind" directive sets a binding address which the outgoing connections 
will use.

aa68eb8540 Whoops. The previous include only had the code conditionally removed. 
Remove for real this time.

1db154464e Removed the call to inet_aton() since the gethostbyname() function handles 
the dotted-decimal case itself.

73a53daf38 Removed the call to hstrerror() in the getpeer_string() function. It's 
not available on all machines.

3e60a5b819 Removed the LOOKUP_LOCK() and LOOKUP_UNLOCK() macros since I believe I 
need locking around both gethostbyname() and gethostbyaddr() at the same
time.

0e4436a070 Tightened the lookup_domain() function. 2002-04-16 03:21:46 +00:00

4b7de22999 Added a test to make sure the "whole_buffer" could be allocated. 2002-04-15 04:16:01 +00:00

c86d22226f Added additional error handling for the bind() and listen() system calls 
when setting up the listening socket.

be47c1791d Modified the opensock() function to respect the Listen directive. If it's 
set, bind all outgoing addresses to this local address.

b10221fa07 Added the write_message() function (from reqs.c) 2001-12-24 00:01:32 +00:00

7240af4333 Changed the calls to write() to send() so that we can use send(..., 
MSG_NOSIGNAL) and not get signals sent to the process. (easier for
debugging and the system doesn't need to worry about signals.)

fdb4952e5f Added the assert() calls to safe_write() to make sure the arguments are 
sane.
 2001-12-17 00:00:24 +00:00

b969ed4302 Changed safe_write() to fully send all the data in the buffer it was 
passed. Also safe_write() and safe_read() now use char pointer buffers
rather than the void pointer style.

a4934e2232 Added the host name lookup code (which use to be in the DNS caching 
system.)

8dc7035fbc Add support to limit the maximum size of the input line (to 128KB which 
should be _more_ than enough for any header line. :)

fd3b313e9f Style changes. Also replaces all mallocs with safemalloc, etc. 2001-11-23 01:18:43 +00:00

d08d088d4a Replaced the readline() function with a new version which has no 
restrictions on the length of a line (unless you fill memory of course.)
Reformated the source.

dde4e9adcc Changed the read() call into a recv() call with a flag of NOSIGNAL since I 
don't want signals messing up my calling conventions.

a746b9d0b2 Moved the zero-length string setting to outside the tests in getpeer_*() 
functions. Also added a more robust error reporting for DNS errors.
 2001-10-23 03:57:34 +00:00

a6a026cb9e Changed the getpeer_*() functions to return the reason why the name or IP 
address could not be looked up.

ad743c1e41 Fixed a problem where a user's variable would be uninitialized if a DNS 
lookup failed.

b9c4c480d2 Moved the safe_write() and safe_read() functions here. 2001-09-16 20:11:07 +00:00

fcff398f31 Cleaned up the locking code to make it more fine grained. Did this since 
dncache.c has locking itself now.

42b09e5441 Removed the SA define. 
Made the sock_mutex static since it's not referenced outside the file.
Changed the data types for some of the variables.
Cleaned up the readline function (changed data types and removed
variables.)

d32e0d1ccb Added ASSERT statements. 2001-05-23 18:01:23 +00:00

f6b7fe3f5c Needed locking in getpeer_string(). 
Added mutex locking around the dnscache() call.
Removed the global sockaddr and setup_fd variables.
Added the socket_blocking() and socket_nonblocking() functions.
Gutted the readling() function and replaced it with something similar to
the 1.0 version. :)
