[BIGMOVE] exploded the monolithic haproxy.c file into multiple files. The files are now stored under : - include/haproxy for the generic includes - include/types.h for the structures needed within prototypes - include/proto.h for function prototypes and inline functions - src/*.c for the C files Most include files are now covered by LGPL. A last move still needs to be done to put inline functions under GPL and not LGPL. Version has been set to 1.3.0 in the code but some control still needs to be done before releasing.

REORG: sock_raw: rename the files raw_sock* The "raw_sock" prefix will be more convenient for naming functions as it will be prefixed with the data layer and suffixed with the data direction. So let's rename the files now to avoid any further confusion. The #include directive was also removed from a number of files which do not need it anymore.

REORG: use the name sock_raw instead of stream_sock We'll soon have an SSL socket layer, and in order to ease the difference between the two, we use the name "sock_raw" to designate the one which directly talks to the sockets without any conversion.

[MEDIUM] separate protocol-level accept() from the frontend's For a long time we had two large accept() functions, one for TCP sockets instanciating proxies, and another one for UNIX sockets instanciating the stats interface. A lot of code was duplicated and both did not work exactly the same way. Now we have a stream_sock layer accept() called for either TCP or UNIX sockets, and this function calls the frontend-specific accept() function which does the rest of the frontend-specific initialisation. Some code is still duplicated (session & task allocation, stream interface initialization), and might benefit from having an intermediate session-level accept() callback to perform such initializations. Still there are some minor differences that need to be addressed first. For instance, the monitor nets should only be checked for proxies and not for other connection templates. Last, we renamed l->private as l->frontend. The "private" pointer in the listener is only used to store a frontend, so let's rename it to eliminate this ambiguity. When we later support detached listeners (eg: FTP), we'll add another field to avoid the confusion.

CLEANUP: sock_raw: remove last references to stream_sock We also stop exporting all functions since they're not needed anymore outside of sock_raw.c.

[MAJOR] rework of the server FSM srv_state has been removed from HTTP state machines, and states have been split in either TCP states or analyzers. For instance, the TARPIT state has just become a simple analyzer. New flags have been added to the struct buffer to compensate this. The high-level stream processors sometimes need to force a disconnection without touching a file-descriptor (eg: report an error). But if they touched BF_SHUTW or BF_SHUTR, the file descriptor would not be closed. Thus, the two SHUT?_NOW flags have been added so that an application can request a forced close which the stream interface will be forced to obey. During this change, a new BF_HIJACK flag was added. It will be used for data generation, eg during a stats dump. It prevents the producer on a buffer from sending data into it. BF_SHUTR_NOW /* the producer must shut down for reads ASAP */ BF_SHUTW_NOW /* the consumer must shut down for writes ASAP */ BF_HIJACK /* the producer is temporarily replaced */ BF_SHUTW_NOW has precedence over BF_HIJACK. BF_HIJACK has precedence over BF_MAY_FORWARD (so that it does not need it). New functions buffer_shutr_now(), buffer_shutw_now(), buffer_abort() are provided to manipulate BF_SHUT* flags. A new type "stream_interface" has been added to describe both sides of a buffer. A stream interface has states and error reporting. The session now has two stream interfaces (one per side). Each buffer has stream_interface pointers to both consumer and producer sides. The server-side file descriptor has moved to its stream interface, so that even the buffer has access to it. process_srv() has been split into three parts : - tcp_get_connection() obtains a connection to the server - tcp_connection_failed() tests if a previously attempted connection has succeeded or not. - process_srv_data() only manages the data phase, and in this sense should be roughly equivalent to process_cli. Little code has been removed, and a lot of old code has been left in comments for now.
