List.h was missing for LIST_ADDQ(). A few unneeded includes of action.h
were removed from certain files.
This one still relies on applet.h and stick-table.h.
Half of the users of this include only need the type definitions and
not the manipulation macros nor the inline functions. Moves the various
types into mini-clist-t.h makes the files cleaner. The other one had all
its includes grouped at the top. A few files continued to reference it
without using it and were cleaned.
In addition it was about time that we'd rename that file, it's not
"mini" anymore and contains a bit more than just circular lists.
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.
This patch introduces the 'http-after-response' rules. These rules are evaluated
at the end of the response analysis, just before the data forwarding, on ALL
HTTP responses, the server ones but also all responses generated by
HAProxy. Thanks to this ruleset, it is now possible for instance to add some
headers to the responses generated by the stats applet. Following actions are
supported :
* allow
* add-header
* del-header
* replace-header
* replace-value
* set-header
* set-status
* set-var
* strict-mode
* unset-var
Functions to deinitialize the HTTP rules are buggy. These functions does not
check the action name to release the right part in the arg union. Only few info
are released. For auth rules, the realm is released and there is no problem
here. But the regex <arg.hdr_add.re> is always unconditionally released. So it
is easy to make these functions crash. For instance, with the following rule
HAProxy crashes during the deinit :
http-request set-map(/path/to/map) %[src] %[req.hdr(X-Value)]
For now, These functions are simply removed and we rely on the deinit function
used for TCP rules (renamed as deinit_act_rules()). This patch fixes the
bug. But arguments used by actions are not released at all, this part will be
addressed later.
This patch must be backported to all stable versions.
These ones are mostly called from cfgparse.c for the parsing and do
not depend on the HTTP representation. The functions's prototypes
were moved to proto/http_rules.h, making this file work exactly like
tcp_rules. Ideally we should stop calling these functions directly
from cfgparse and register keywords, but there are a few cases where
that wouldn't work (stats http-request) so it's probably not worth
trying to go this far.
