[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.

/*
[CLEANUP] rename client -> frontend The 'client.c' file now only contained frontend-specific functions, so it has naturally be renamed 'frontend.c'. Same for client.h. This has also been an opportunity to remove some cross references from files that should not have depended on it. In the end, this file should contain a protocol-agnostic accept() code, which would initialize a session, task, etc... based on an accept() from a lower layer. Right now there are still references to TCP.

[MINOR] tcp: add support for dynamic MSS setting By passing a negative value to the "mss" argument of "bind" lines, it becomes possible to subtract this value to the MSS advertised by the client, which results in segments smaller than advertised. The effect is useful with some TCP stacks which ACK less often when segments are not full, because they only ACK every other full segment as suggested by RFC1122. NOTE: currently this has no effect on Linux kernel 2.6, a kernel patch is still required to change the MSS of established connections.

REORG: include: move acl.h to haproxy/acl.h{,-t}.h The files were moved almost as-is, just dropping arg-t and auth-t from acl-t but keeping arg-t in acl.h. It was useful to revisit the call places since a handful of files used to continue to include acl.h while they did not need it at all. Struct stream was only made a forward declaration since not otherwise needed.

REORG: include: update all files to use haproxy/api.h or api-t.h if needed All files that were including one of the following include files have been updated to only include haproxy/api.h or haproxy/api-t.h once instead: - common/config.h - common/compat.h - common/compiler.h - common/defaults.h - common/initcall.h - common/tools.h The choice is simple: if the file only requires type definitions, it includes api-t.h, otherwise it includes the full api.h. In addition, in these files, explicit includes for inttypes.h and limits.h were dropped since these are now covered by api.h and api-t.h. No other change was performed, given that this patch is large and affects 201 files. At least one (tools.h) was already freestanding and didn't get the new one added.

REORG: include: move http_ana.h to haproxy/http_ana{,-t}.h It was moved without any change, however many callers didn't need it at all. This was a consequence of the split of proto_http.c into several parts that resulted in many locations to still reference it.

REORG: include: move log.h to haproxy/log{,-t}.h The current state of the logging is a real mess. The main problem is that almost all files include log.h just in order to have access to the alert/warning functions like ha_alert() etc, and don't care about logs. But log.h also deals with real logging as well as log-format and depends on stream.h and various other things. As such it forces a few heavy files like stream.h to be loaded early and to hide missing dependencies depending where it's loaded. Among the missing ones is syslog.h which was often automatically included resulting in no less than 3 users missing it. Among 76 users, only 5 could be removed, and probably 70 don't need the full set of dependencies. A good approach would consist in splitting that file in 3 parts: - one for error output ("errors" ?). - one for log_format processing - and one for actual logging.

REORG: include: move proxy.h to haproxy/proxy{,-t}.h This one is particularly difficult to split because it provides all the functions used to manipulate a proxy state and to retrieve names or IDs for error reporting, and as such, it was included in 73 files (down to 68 after cleanup). It would deserve a small cleanup though the cut points are not obvious at the moment given the number of structs involved in the struct proxy itself.

REORG: include: move sample.h to haproxy/sample{,-t}.h This one is particularly tricky to move because everyone uses it and it depends on a lot of other types. For example it cannot include arg-t.h and must absolutely only rely on forward declarations to avoid dependency loops between vars -> sample_data -> arg. In order to address this one, it would be nice to split the sample_data part out of sample.h.

REORG: include: move stream.h to haproxy/stream{,-t}.h This one was not easy because it was embarking many includes with it, which other files would automatically find. At least global.h, arg.h and tools.h were identified. 93 total locations were identified, 8 additional includes had to be added. In the rare files where it was possible to finalize the sorting of includes by adjusting only one or two extra lines, it was done. But all files would need to be rechecked and cleaned up now. It was the last set of files in types/ and proto/ and these directories must not be reused anymore.

REORG/MAJOR: session: rename the "session" entity to "stream" With HTTP/2, we'll have to support multiplexed streams. A stream is in fact the largest part of what we currently call a session, it has buffers, logs, etc. In order to catch any error, this commit removes any reference to the struct session and tries to rename most "session" occurrences in function names to "stream" and "sess" to "strm" when that's related to a session. The files stream.{c,h} were added and session.{c,h} removed. The session will be reintroduced later and a few parts of the stream will progressively be moved overthere. It will more or less contain only what we need in an embryonic session. Sample fetch functions and converters will have to change a bit so that they'll use an L5 (session) instead of what's currently called "L4" which is in fact L6 for now. Once all changes are completed, we should see approximately this : L7 - http_txn L6 - stream L5 - session L4 - connection | applet There will be at most one http_txn per stream, and a same session will possibly be referenced by multiple streams. A connection will point to a session and to a stream. The session will hold all the information we need to keep even when we don't yet have a stream. Some more cleanup is needed because some code was already far from being clean. The server queue management still refers to sessions at many places while comments talk about connections. This will have to be cleaned up once we have a server-side connection pool manager. Stream flags "SN_*" still need to be renamed, it doesn't seem like any of them will need to move to the session.

/* Finish a stream accept() for a proxy (TCP or HTTP). It returns a negative
[BUG] accept: don't close twice upon error The stream_sock's accept() used to close the FD upon error, but this was also sometimes performed by the frontend's accept() called via the session's accept(). Those interlaced calls were also responsible for the spaghetti-looking error unrolling code in session.c and stream_sock.c. Now the frontend must not close the FD anymore, the session is responsible for that. It also takes care of just closing the FD or also removing from the FD lists, depending on its state. The socket-level accept() does not have to care about that anymore.

int frontend_accept(struct stream *s)
[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.

if (s->logs.logwait & LW_CLIP)
BUG/MINOR: log: make log-format, unique-id-format and add-header more independant It happens that all of them call parse_logformat_line() which sets proxy->to_log with a number of flags affecting the line format for all three users. For example, having a unique-id specified disables the default log-format since fe->to_log is tested when the session is established. Similarly, having "option logasap" will cause "+" to be inserted in unique-id or headers referencing some of the fields depending on LW_BYTES. This patch first removes most of the dependency on fe->to_log whenever possible. The first possible cleanup is to stop checking fe->to_log for being null, considering that it always contains at least LW_INIT when any such usage is made of the log-format! Also, some checks are wrong. s->logs.logwait cannot be nulled by "logwait &= ~LW_*" since LW_INIT is always there. This results in getting the wrong log at the end of a request or session when a unique-id or add-header is set, because logwait is still not null but the log-format is not checked. Further cleanups are required. Most LW_* flags should be removed or at least replaced with what they really mean (eg: depend on client-side connection, depend on server-side connection, etc...) and this should only affect logging, not other mechanisms. This patch fixes the default log-format and tries to limit interferences between the log formats, but does not pretend to do more for the moment, since it's the most visible breakage.

[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.

A new stream, and thus a new TXN, is created for each request. In addition, the function responsible to end the TXN is now also reponsible to release it.

[MAJOR] frontend: split accept() into frontend_accept() and session_accept() A new function session_accept() is now called from the lower layer to instanciate a new session. Once the session is instanciated, the upper layer's frontent_accept() is called. This one can be service-dependant. That way, we have a 3-phase accept() sequence : 1) protocol-specific, session-less accept(), which is pointed to by the listener. It defaults to the generic stream_sock_accept(). 2) session_accept() which relies on a frontend but not necessarily for use in a proxy (eg: stats or any future service). 3) frontend_accept() which performs the accept for the service offerred by the frontend. It defaults to frontend_accept() which is really what is used by a proxy. The TCP/HTTP proxies have been moved to this mode so that we can now rely on frontend_accept() for any type of session initialization relying on a frontend. The next step will be to convert the stats to use the same system for the stats.

[BUG] accept: don't close twice upon error The stream_sock's accept() used to close the FD upon error, but this was also sometimes performed by the frontend's accept() called via the session's accept(). Those interlaced calls were also responsible for the spaghetti-looking error unrolling code in session.c and stream_sock.c. Now the frontend must not close the FD anymore, the session is responsible for that. It also takes care of just closing the FD or also removing from the FD lists, depending on its state. The socket-level accept() does not have to care about that anymore.

BUG/MEDIUM: prevent gcc from moving empty keywords lists into BSS Benoit Dolez reported a failure to start haproxy 1.5-dev19. The process would immediately report an internal error with missing fetches from some crap instead of ACL names. The cause is that some versions of gcc seem to trim static structs containing a variable array when moving them to BSS, and only keep the fixed size, which is just a list head for all ACL and sample fetch keywords. This was confirmed at least with gcc 3.4.6. And we can't move these structs to const because they contain a list element which is needed to link all of them together during the parsing. The bug indeed appeared with 1.5-dev19 because it's the first one to have some empty ACL keyword lists. One solution is to impose -fno-zero-initialized-in-bss to everyone but this is not really nice. Another solution consists in ensuring the struct is never empty so that it does not move there. The easy solution consists in having a non-null list head since it's not yet initialized. A new "ILH" list head type was thus created for this purpose : create an Initialized List Head so that gcc cannot move the struct to BSS. This fixes the issue for this version of gcc and does not create any burden for the declarations.

MAJOR: acl: store the ACL argument types in the ACL keyword declaration The types and minimal number of ACL keyword arguments are now stored in their declaration. This will allow many more fantasies if some ACL use several arguments or types. Doing so required to rework all ACL keyword declarations to add two parameters. So this was a good opportunity for a general cleanup and to sort all entries in alphabetical order. We still have two pending issues : - parse_acl_expr() checks for errors but has no way to report them to the user ; - the types of some arguments are still not resolved and kept as strings (eg: ARGT_FE/BE/TAB) for compatibility reasons, which must be resolved in acl_find_targets()

MEDIUM: init: convert all trivial registration calls to initcalls This switches explicit calls to various trivial registration methods for keywords, muxes or protocols from constructors to INITCALL1 at stage STG_REGISTER. All these calls have in common to consume a single pointer and return void. Doing this removes 26 constructors. The following calls were addressed : - acl_register_keywords - bind_register_keywords - cfg_register_keywords - cli_register_kw - flt_register_keywords - http_req_keywords_register - http_res_keywords_register - protocol_register - register_mux_proto - sample_register_convs - sample_register_fetches - srv_register_keywords - tcp_req_conn_keywords_register - tcp_req_cont_keywords_register - tcp_req_sess_keywords_register - tcp_res_cont_keywords_register - flt_register_keywords

INITCALL1(STG_REGISTER, acl_register_keywords, &acl_kws);
[MEDIUM] added several ACL criteria and matches Many ACL criteria have been added. Some others are still commented out because some functions are still missing.

[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.
