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.

47ab97a347 Fixed up a spelling mistake and changed various bits of code to take 
advantage of the fact that the peer's socket information is now stored
inside the connection structure.
 2002-05-23 18:24:46 +00:00

1f9085cef2 Added the "DNSserverLocation" and "DNSserverSocket" directives for use 
with the "dnsserver" resolver.

09b1b9b925 Added the peer's socket information to the connection structure. The 
information is passed along during the initialization of the structure.

9d0c65ad86 Fixed up the header includes for the new layout. 
Changed one line of code to make it explicit how the pointers are to be
updated.

451fad1ed2 Changed the header includes around to reflect the new source layout. 2002-05-23 18:20:27 +00:00

e633b97957 Added code to create the "dnsserver" program, and also reorganized to 
include the various new source files.

1690c05075 Initial addition to CVS. Moved the three "text" related functions into a 
separate file.

fd3e6e84fb Initial addition to CVS. Moved the network related functions into a 
separate module.

c667952861 Initial addition to CVS. Moved all the debugging heap related functions. 2002-05-23 04:41:10 +00:00

0b0e03fa39 Initial addition to CVS. The dnsserver process is a child executable that 
handle DNS resolving.
 2002-05-23 04:40:42 +00:00

d22d6d181b Initial addition to CVS. These functions create an API for accessing the 
dnsserver child process.
 2002-05-23 04:40:06 +00:00

2ee61db6af Initial addition into CVS. Moves various functions relating the daemon 
processes.  Added a portable signal handler setting function.
 2002-05-23 04:39:32 +00:00

65cf5ea290 Initial addition to CVS. This header moves all the system includes from 
the tinyproxy.h file to here.

700f129750 Set the pointer to NULL after it's been freed() 2002-05-17 16:39:35 +00:00
Robert James Kaes
e4e78e0f1b request->host might have been freed by the time we get to 
free_request_struct(), so make sure it's pointing to memory.
 2002-05-17 16:34:42 +00:00

bb9f206529 Moved the definition of the struct buffer_s into the buffer.c file and out 
of the buffer.h file.  This also required the removal of the BUFFER_SIZE
macro, and replace it with the buffer_size() function.

d46cba8a0b Added a "tail" pointer to the vector to make insertions more efficient. 2002-05-13 23:32:16 +00:00
Robert James Kaes
16e96c79e8 Thanks to Justin Guyett for making the hashmap_insert() function use a 
constant time insert.  Explanation: new enteries are added to the _front_
of the chain, rather than search to the end.

73e3b495e0 Fixed up a potential SEGFAULT if memory for an entry could not be 
allocated.  Also, thanks to Justin Guyett for finding a problem the
hashmap_remove() function.  There was a problem where an entry's "prev"
pointer could be pointing to freed memory.

Finally, renamed all "maps" to bucket to make the source more
understandable.

cf2ecb83b8 Removed the request logging in the tunnel because it breaks the tunnel 
concept since it blocks waiting for information from the client before any
data from the remote is relayed.
 2002-05-08 03:29:23 +00:00

0a1f83bbe5 tinyproxy should be installed into the /sbin directory rather than the 
/bin directory since it's a network daemon.

3284f365b2 Check the return value of the write_message() function. 2002-04-28 20:03:53 +00:00
Robert James Kaes
ed90a4676f Added more error checking in process_client_headers() and 
process_server_headers() functions.

Also, better reporting of errors back to the client.

f79807ac11 Added extra logging information, and made sure that locks were being 
released properly.

e4fe04cbaf Clear the total array of threads before any of the threads are created. 2002-04-28 03:09:52 +00:00
Robert James Kaes
577f3cebbf Fixed up the error detection code when relating the pthread functions. 
They return 0 if OK, and a positive error code.

Cleaned up the status setting code in thread_main().

Thanks to Hans-Georg Bork for fixing the problem in thread_pool_create()
where the status wasn't set early enough to allow all the threads to be
created.

Added additional logging information to let the admin know what is
happening with the thread creation.

1a8c914dd2 Changed the len type to ssize_t because we need to detect errors in the 
recv() call.  Thanks to Tom Cross for discovering this bug.

1d78e63233 Added an assert in hashmap_first() 2002-04-26 16:51:29 +00:00

e9f5b2e75f Check the return value of hashmap_first() 2002-04-26 16:50:55 +00:00
Robert James Kaes
0e7182533c Need to check the return value of hashmap_first() since it could be 
negative.

6992c74bba Check to see if request->path is actually allocated before trying to free 
it.

b4ef24844f First change all the hashmap related calls to use the new API. 
The remove_connection_headers() function now handles both the Connection
header _and_ the Proxy-Connection header.
 2002-04-25 18:58:08 +00:00

d1031e2c8f The hashmap API changed, so this function needs to be changed as well. 2002-04-25 18:56:43 +00:00
Robert James Kaes
ce51a74045 Removed the hashmap_keys() function and added the "iterator" concept. 
This required a bunch of changes to the source (like the inclusion of the
end_iterator member variable.)  All this was required by sites like Yahoo
which send out multiple "Set-Cookie" headers.  tinyproxy needs to handle
this situation correctly.

b5df4f1cf0 hashmap_search() only takes two arguments, so removed the unneeded NULL. 2002-04-25 18:52:09 +00:00
Robert James Kaes
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.)
 2002-04-24 16:48:34 +00:00
Robert James Kaes
335d787018 Fixed a couple of problems where tinyproxy was trying to free a memory 
block which had not been allocated.

Also, the "proxy-connection" to the list of headers we don't pass.
 2002-04-24 16:47:19 +00:00

89ada2df28 Moved bind_address inside the config structure. 2002-04-24 16:45:45 +00:00
Robert James Kaes
c5b9ec889e Renamed the LOCKing macros and added assert debugging code. Also, moved 
the mutex initialization into a function call so that I can use an
error checking mutex once I figure out how to get it to work on my
computer.

08077cc9e1 The "Bind" directive sets a binding address which the outgoing connections 
will use.
 2002-04-22 19:35:24 +00:00
Robert James Kaes
1953348c90 Added the "Proxy-Connection" header to the list of client headers which 
are not passed along.
 2002-04-22 19:34:50 +00:00

2ec7a4dd72 The log_message() function now stores the messages if the configuration 
file has not been read yet.  The reason for this is that we don't know
where to log the messgaes until _after_ the config file has been
processed.
 2002-04-22 19:34:20 +00:00
Robert James Kaes
60f61c8f0c Added the "Bind" directive. 2002-04-22 19:33:01 +00:00

aa68eb8540 Whoops. The previous include only had the code conditionally removed. 
Remove for real this time.
 2002-04-18 21:54:50 +00:00

1db154464e Removed the call to inet_aton() since the gethostbyname() function handles 
the dotted-decimal case itself.
 2002-04-18 21:53:33 +00:00
Robert James Kaes
60f0a86c75 The stats now wait until after the client has finished sending all its 
headers before sending the HTTP response back.  This should be more
standards compliant.

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

d14b612e13 Fixed a memory leak in the hashmap_delete function. The array of maps was 
not being deleted.
 2002-04-18 18:40:38 +00:00

9a8d732a13 Changed all calls to strdup to safestrdup. This should provide better 
memory usage tracking.
