When running "haproxy -v", we still get "HA-Proxy" which is the last
place where this confusing oddity happens. Being so used to it I didn't
even notice it until it was reported to me just after 2.2 but it never
got fixed, despite the PRODUCT_NAME macro that is used to report the
name in the stats page and in "show info" being already set to "HAProxy"
15 years ago in 1.2.14 with commit e03312613. It's about time to
uniformize everything.
This one comes with a very deep dependency hell, only to know that
process_stream() is a function. Dropping it reduces the preprocessed
output from 1.5MB to 640kB.
These ones are used by virtually every config parser. Not only they
provide no benefit in being inlined, but they imply a very deep
dependency starting at proxy.h, which results for example in task.c
including openssl.
Let's move these two functions to cfgparse.c.
This function has no business being inlined in stick_table.h since it's
only used at boot time by the config parser. In addition it causes an
undesired dependency on tools.h because it uses parse_time_err(). Let's
move it to stick_table.c.
No idea why this was put inlined into connection.h, it's used only once
for haproxy -vv, and requires tools.h, causing an undesired dependency
from connection.h. Let's move it to connection.c instead where it ought
to have been.
Only mworker uses proc_self, and it was declared in global.h, forcing
users of global.h to include mworker and its dependencies.
Moving it to mworker reduces the preprocessed size of version.c from
170 to 125kB by shrinking the number of local includes from 30 to 16
and the number of system includes from 147 to 132.
The presence of this field causes a long dependency chain because almost
everyone includes global-t.h, and vars include sample_data which include
some system includes as well as HTTP parts.
There is absolutely no reason for having the process-wide variables in
the global struct, let's just move them into vars.c and vars.h. This
reduces from ~190k to ~170k the preprocessed output of version.c.
This one is stated as experimental in the doc but could still be used
by accidental copy-paste. Let's mark it with KWF_EXPERIMENTAL so that
users have to opt-in to use it.
Now "show info float" will also report SSL rates, connection rates and
key reuse ratios as floats. This can be convenient at very low rates.
Note that the SSL reuse ratio which used to commonly oscillate between
0 and 1 under load is now more often above zero with small values. It
indicates that for better stability we shouldn't be comparing a key rate
with a connection rate but instead we should measure the reuse rate at
its source.
We'll have to support reporting sub-second uptimes, so let's use the
appropriate function which will automatically adjust the tv_usec field.
In addition to this, it will also report a more accurate uptime thanks
to considering the sub-second part in the result.
This will allow some fields to be produced with a higher accuracy when
the requester indicates being able to parse floats. Rates and times are
among the elements which can make sense.
Currently the stats filling function knows nothing about the caller's
needs, so let's pass the STAT_* flags so that it can adapt to the
requester's constraints.
