When Lua is disabled, the alternate functions must have the same
prototype as the original ones, otherwise we get such warnings :
src/stream.c:278:27: warning: too many arguments in call to 'hlua_ctx_destroy'
hlua_ctx_destroy(&s->hlua);
~~~~~~~~~~~~~~~~ ^
No backport is needed.
If we are writing in the request buffer, we are not waked up
when the data are forwarded because it is useles. The request
analyzers are waked up only when data is incoming. So, if the
request buffer is full, we set the WAKE_ON_WRITE flag.
Before this patch, each yield in a Lua action set a flags to be
waked up when some activity were detected on the response channel.
This behavior causes loop in the analyzer process.
This patch set the wake up on response buffer activity only if we
really want to be waked up on this activity.
This flag indicate that the current yield is returned by the Lua
execution task control. If this flag is set, the current task may
quit but will be set in the run queue to be re-executed immediatly.
This patch modify the "hlua_yieldk()" function, it adds an argument
that contain a field containing yield options.
In the future, the lua execution must return scheduling informations.
We want more than one flag, so I convert an integer used with an
enum into an interer used as bitfield.
This system permits to execute some lua function after than HAProxy
complete his initialisation. These functions are executed between
the end of the configuration parsing and check and the begin of the
scheduler.
This is the first step of the lua integration. We add the useful
files in the HAProxy project. These files contains the main
includes, the Makefile options and empty initialisation function.
Is is the LUA skeleton.
