The test innodb_fts.fulltext_table_evict was only creating 1000 tables
with fulltext indexes, only to check that no tables with fulltext
indexes are being evicted.
The reason why tables containing fulltext indexes cannot be evicted is
that fts_optimize_init() invokes dict_table_prevent_eviction().
Remove the test, because it easily fails with a result difference.
Analysis by Thirunarayanan Balathandayuthapani:
By default, innodb_encrypt_tables=0.
1) Test case creates 100 tables in innodb_encrypt_1.
2) creates another 100 unencrypted tables (encryption=off) in innodb_encrypt_2
3) creates another 100 encrypted tables (encryption=on) in innodb_encrypt_3
4) enabling innodb_encrypt_tables=1 and checking that only
100 encrypted tables exist. (already we have 100 in dictionary)
5) opening all tables again (no idea why)
6) After that, set innodb_encrypt_tables=0 and wait for 100 tables
to be decrypted (already we have 100 unencrypted tables)
7) dropping all databases
Sporadic failure happens because after step 4, it could encrypt the
normal table too, because innodb_encryption_threads=4.
This test was added in MDEV-9931, which was about InnoDB startup being
slow due to all .ibd files being opened. There have been a number of
later fixes to this problem. Currently the latest one is
commit cad56fbaba, in which some tests
(in particular the test innodb.alter_kill) could fail if all InnoDB
.ibd files are read during startup. That could make this test redundant.
Let us remove the test, because it is big, slow, unreliable, and
does not seem to reliably catch the problem that all files are being
read on InnoDB startup.
The list was created based on 10.2.15 list, with the addition
of failures and modifications which happened during the last week
before the tentative 10.3.7 release commit
