The code is working again, but not as clean as it could be.
Many blocks should still move to dedicated functions. req->h
must be removed everywhere and updated everytime needed.
A few functions or macros should take care of the headers
during header insertion/deletion/change.
The new parser uses an FSM to strictly follow RFC2616.
Headers are indexed and parsed only once they're all available.
That way, complex regexes make more sense.
HTTP processing is now performed in several phases by calling
multiple functions, making the code cleaner and easier to read.
Note that req[i]pass does not work anymore because it would
require that we mark a header to be ignored. What is really
needed is to have the ability to add an exception to a matching
(match xx except yy).
Several bugs have been fixed in appsession during the conversion
to the new FSM (method length and recovery on malloc errors).
The code does build and work with the debug examples, but is
not usable yet to connect to anything as it does not forward
the requests yet.
This patch was added in 1.2.9 but was then incidentely reverted by
manipulation error when merging next patch (enforce max number of
conns). It's now merged again.
The references to the proxy from the session have been turned into
Frontend (fe), Filters (fi) and Backend (be). This should ease the
migration to the L7 switching features. Next step will be to kill
the struct proxy and have 3 independant structs instead, each
referenced from entities called listener, frontend, filters and
backend.
As suggested by Markus Elfring, a few "const char *" have replaced
some "char *" declarations where a function is not expected to
modify a value. It does not change the code but it helps detecting
coding errors.
Since the connection queueing was introduced, the "redispatch"
option could not cover the cases where a connection has been
refused by the server after having been marked "in progress".
The fix consists in doing a redispatch in the delayed connection
handling code.
Problem reported by Konrad Rzentarzewski.
It is now possible to tarpit connections based on regex matches.
The tarpit timeout is equal to the contimeout. A 500 server error
response is faked, and the logs show the status flags as "PT" which
indicate the connection has been tarpitted.
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.
