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.
Several times some users have expressed the non-intuitive aspect of some
of our stat/info metrics and suggested to add some help. This patch
replaces the char* arrays with an array of name_desc so that we now have
some reserved room to store a description with each stat or info field.
These descriptions are currently empty and not reported yet.
It is now possible to format stats counters as floats. But the stats applet does
not use it.
This patch is required by the Prometheus exporter to send the time averages in
seconds. If the promex change is backported, this patch must be backported
first.
The status codes definition (STAT_STATUS_*) and their string representation
stat_status_codes) have been moved in stats files. There is no reason to keep
them in proto_http files.
Now all the code used to manipulate chunks uses a struct buffer instead.
The functions are still called "chunk*", and some of them will progressively
move to the generic buffer handling code as they are cleaned up.
It already returns an empty string when the field is empty, but as a
preventive measure we should do the same when the string itself is a
NULL. While it is not supposed to happen, it will make the code more
resistant against failed allocations and unexpected results.
This fix should be backported to 1.7.
Move the "show stat" command to stats.c using the CLI keyword API
to register it on the CLI. The stats_dump_stat_to_buffer() function
is now static again.
proto/dumpstats.h has been split in 4 files:
* proto/cli.h contains protypes for the CLI
* proto/stats.h contains prototypes for the stats
* types/cli.h contains definition for the CLI
* types/stats.h contains definition for the stats
