This patch is the first of a serie which merge all the action structs. The
function "tcp-request content", "tcp-response-content", "http-request" and
"http-response" have the same values and the same process for some defined
actions, but the struct and the prototype of the declared function are
different.
This patch try to unify all of these entries.
With the difference between the "struct sample" data and the
"struct sample_storage" data, it was not possible to write
data = data, and we did a memcpy. This patch remove some of
these memcpy.
The union name "data" is a little bit heavy while we read the source
code because we can read "data.data.sint". The rename from "data" to "u"
makes the read easiest like "data.u.sint".
This patch remove the struct information stored both in the struct
sample_data and in the striuct sample. Now, only thestruct sample_data
contains data, and the struct sample use the struct sample_data for storing
his own data.
Some function are just a wrappers. This patch reduce the size of
this wrapper for improving the readability. One check is moved
from the wrapper to the main function, and some middle vars are
removed.
This patch removes the 32 bits unsigned integer and the 32 bit signed
integer. It replaces these types by a unique type 64 bit signed.
This makes easy the usage of integer and clarify signed and unsigned use.
With the previous version, signed and unsigned are used ones in place of
others, and sometimes the converter loose the sign. For example, divisions
are processed with "unsigned", if one entry is negative, the result is
wrong.
Note that the integer pattern matching and dotted version pattern matching
are already working with signed 64 bits integer values.
There is one user-visible change : the "uint()" and "sint()" sample fetch
functions which used to return a constant integer have been replaced with
a new more natural, unified "int()" function. These functions were only
introduced in the latest 1.6-dev2 so there's no impact on regular
deployments.
Commit 4834bc7 ("MEDIUM: vars: adds support of variables") brought a bug.
Setting a variable from an expression that doesn't resolve infinitely
blocks the processing.
The internal actions API must be changed to let the caller pass the various
flags regarding the state of the analysis (SMP_OPT_FINAL).
For now we only fix the issue by making the action_store() function always
return 1 to prevent any blocking.
No backport is needed.
We'll need to move the session variables to the session. For this, the
accounting must not depend on the stream. Instead we pass the pointers
to the different lists.
A switch case doesn't have default entry, and the compilator sends
a warning about uninitilized var.
warning: 'vars' may be used uninitialized in this function [-Wmaybe-uninitialized]
This patch adds two functions used for variable acces using the
variable full name. If the variable doesn't exists in the variable
pool name, it is created.
This patch adds support of variables during the processing of each stream. The
variables scope can be set as 'session', 'transaction', 'request' or 'response'.
The variable type is the type returned by the assignment expression. The type
can change while the processing.
The allocated memory can be controlled for each scope and each request, and for
the global process.
