# title: Performance problem when using SRP plugin
|
|
# decription:
|
|
# :::::::::::::::::::: N O T A B E N E :::::::::::::::::
|
|
# It is crusial for this test that firebird.conf have following _SEQUENCE_ of auth-plugins: Srp, ..., Legacy_Auth
|
|
# -- i.e. Srp must be specified BEFORE Legacy.
|
|
# Slow time of attach establishing can NOT be seen otherwise; rather almost no difference will be in that case.
|
|
# :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
|
|
#
|
|
# Test creates two users: one usingLegacy plugin and second using Srp.
|
|
# Then we make ~20...30 pairs of attach/detach by each of these users and get total time difference for these actions.
|
|
# Ratio between these total differences must be limited with threshold. Its value was determined after dozen of runs
|
|
# and it seems to be reasonable assign to it value 1.25 (see MIN_RATIO_THRESHOLD in the code).
|
|
#
|
|
# Test output will contain ALERT if total time of <attaches_using_Srp> vs <attaches_using_Legacy>
|
|
# will be greater than MIN_RATIO_THRESHOLD.
|
|
#
|
|
# Reproduced on on several builds 4.x before 17.01.2020 (tested: 4.0.0.1712 CS, 4.0.0.1731 CS - got ratio = ~1.95).
|
|
# Reproduced also on 3.0.5.33221 Classic - got ratio ~1.50 ... 1.70; could NOT reproduce on 3.0.5 SuperClassic / SuperServer.
|
|
# Checked on:
