A better name was found for the option implemented inec74438("MINOR: hlua: add option to preserve bool type from smp to lua") Indeed, "tune.lua.preserve-smp-bool {on | off}" wasn't explicit enough nor did it encourage the adoption of the new "fixed" behavior (vs historical behavior which is now considered as a bug). Thus it becomes "tune.lua.bool-sample-conversion { normal | pre-3.1-bug }" which actively encourage users to switch the new behavior after having patched in-use Lua script if needed. From a technical point of view, the logic remains the same, as the option currently defaults to "pre-3.1-bug" to prevent script breakage, and a warning is emitted if the option isn't set explicily and Lua is used. Documentation and regtests were updated. Must be backported in 3.1 withec74438andf2838f5("REGTESTS: fix lua-based regtests using tune.lua.smp-preserve-bool")

# BUG/MEDIUM: lua: possible CLOSE-WAIT state with '\n' headers
|
|
#
|
|
# The Lua parser doesn't takes in account end-of-headers containing
|
|
# only '\n'. It expects always '\r\n'. If a '\n' is processes the Lua
|
|
# parser considers it miss 1 byte, and wait indefinitely for new data.
|
|
#
|
|
# When the client reaches their timeout, it closes the connection.
|
|
# This close is not detected and the connection keep in CLOSE-WAIT
|
|
# state.
|
|
#
|
|
# I guess that this patch fix only a visible part of the problem.
|
|
# If the Lua HTTP parser wait for data, the timeout server or the
|
|
# connectio closed by the client may stop the applet.
