Hello HAProxy Org. I'm about to work on implementing dump_all_vars() from issue #1623 as my first contribution to HAProxy. ( https://github.com/haproxy/haproxy/issues/1623) Since this is my first work and a "good first issue", I'd like to confirm the implementation approach before submitting patches.
Proposed Implementation: Function signature: dump_all_vars([scope],[prefix]) Arguments: - scope (optional): variable scope(sess, txn, req, res, proc) - prefix (optional): filter variables by name prefix Output format: varl=var1, var2=var2, ... (string values will be quoted: name="value") Implementation Plan: - Location: src/vars.c - Start with basic types: int, str, bool - Iterate through variables list and filter by scope/prefix - Format output as comma-separated key=value pairs - Leave room for future format extension (e.g., JSON) Example Usage: # Dump all txn variables http-request return string %[dump_all_vars(txn)] # Dump only variables starting with "counter" http-request return string %[dump_all_vars(txn,counter)] Any concerns or suggestions before I proceed? Thanks, Hyeonggeun Oh (github username Geun-Oh).
