Add a sample fetch for the name of a bind. This can be useful to
take decisions when PROXY protocol is used and we can't rely on dst,
such as the sample config below.
defaults
mode http
listen bar
bind 127.0.0.1:1111
server s1 127.0.1.1:1234 send-proxy
listen foo
bind 127.0.1.1:1234 name foo accept-proxy
http-request return status 200 hdr dst %[dst] if { dst 127.0.1.1 }
This regtest validates all hashes that we support, on all input bytes from
0x00 to 0xFF. Those supporting avalanche are tested as well. It also tests
len(), hex() and base64(). It purposely does not enable sha2() because this
one relies on OpenSSL and there's no point in validating that OpenSSL knows
how to hash, what matters is that we can test our hashing functions in all
cases. However since the tests were written, they're still present and
commented out in case that helps.
It may be backported to supported versions, possibly dropping a few algos
that were not supported (e.g. crc32c requires 1.9 minimum).
Note that this test will fail on crc32/djb2/sdbm/wt6 unless patches
"BUG/MINOR: stream: init variables when the list is empty" and
"BUG/MAJOR: hashes: fix the signedness of the hash inputs" are included.
The sample fetche can get srv_name without foreach
`core.backends["bk"].servers`.
Then we can get Server class quickly via
`core.backends[txn.f:be_name()].servers[txn.f:srv_name()]`.
