# title:        Increase number of formats/versions of views from 255 to 32K
# decription:
#                  FB40SS, build 4.0.0.789: OK, 3.828s (SS, CS).
#                  Older version issued:
#                       Statement failed, SQLSTATE = 54000
#                       unsuccessful metadata update
#                       -TABLE VW1
#                       -too many versions
#                  NB: we have to change FW to OFF in order to increase speed of this test run thus use test_type = Python.
#
#                  05.05.2021.
#                  Reduced min_version to 3.0.8 after this feature was backported to FB 3.x, see:
#                  https://github.com/FirebirdSQL/firebird/commit/14eac8b76bb4d2fb339e5387dd86927961e77d46
#
#                  Re-implemented in order to generate SQL script with more than 2K changes of view format
#                  (see 'FORMAT_CHANGES_LIMIT': this value must be multiplied for 2 in order to get actual number of format changes)
#
#                  Checked on intermediate build 3.0.8.33465, timestamp: 05.05.2021 11:26.
#                  Duration: 4.0.0.2465 ~17s; 3.0.8.33465: ~24s
#                  21.05.2021: changed connection protocol to local, time reduced from 19 to 15 seconds.
