| # BUG/MINOR: log: pin the front connection when front ip/ports are logged |
| # |
| # Mathias Weiersmueller reported an interesting issue with logs which Lukas |
| # diagnosed as dating back from commit 9b061e332 (1.5-dev9). When front |
| # connection information (ip, port) are logged in TCP mode and the log is |
| # emitted at the end of the connection (eg: because %B or any log tag |
| # requiring LW_BYTES is set), the log is emitted after the connection is |
| # closed, so the address and ports cannot be retrieved anymore. |
| # |
| # It could be argued that we'd make a special case of these to immediately |
| # retrieve the source and destination addresses from the connection, but it |
| # seems cleaner to simply pin the front connection, marking it "tracked" by |
| # adding the LW_XPRT flag to mention that we'll need some of these elements |
| # at the last moment. Only LW_FRTIP and LW_CLIP are affected. Note that after |
| # this change, LW_FRTIP could simply be removed as it's not used anywhere. |
| # |
| # Note that the problem doesn't happen when using %[src] or %[dst] since |
| # all sample expressions set LW_XPRT. |
