First, not a a direct comment on your patches, but before I forget, I'd
like to point out that there is one more thing which need fixing in
regard to Lua variables:
TXN.set_var(TXN, var, value)
where "var" is noted as:
The var name according with the HAProxy syntax
However, nothing in the code checks that variable name is formed
correctly (with correct prefix, such as "txn."), or that the rest of the
variable name is correct.
Lua code using set_var() with wrong name silently fails, the variable is
not set, and nothing is logged
With your proposal set_var() now can return result, and we could even
log warning for "variable name syntax error".
Now back on topic. Instead of adding more parameters to set_var(), I'd
prefer a warning instead.
If someone is using set_var() from Lua, and that variable is never used
or set in the rest of the config, we would know that. Additionally, one
can set "zero-warning" option to prevent abuse by Lua scripts or to
For your use case, maybe you could use maps from Lua? They should be
backed by ebtree and be faster right?
