Summary of changes
- MD_CTX_SIZE is increased
- EVP_CIPHER_CTX_buf_noconst(ctx) does not work anymore, points
to nobody knows where. The assumption made previously was that
(since the function does not seem to be documented)
was that it points to the last partial source block.
Add own partial block buffer for NOPAD encryption instead
- SECLEVEL in CipherString in openssl.cnf
had been downgraded to 0, from 1, to make TLSv1.0 and TLSv1.1 possible
(according to https://github.com/openssl/openssl/blob/openssl-3.0.0/NEWS.md
even though the manual for SSL_CTX_get_security_level claims that it
should not be necessary)
- Workaround Ssl_cipher_list issue, it now returns TLSv1.3 ciphers,
in addition to what was set in --ssl-cipher
- ctx_buf buffer now must be aligned to 16 bytes with openssl(
previously with WolfSSL only), ot crashes will happen
- updated aes-t , to be better debuggable
using function, rather than a huge multiline macro
added test that does "nopad" encryption piece-wise, to test
replacement of EVP_CIPHER_CTX_buf_noconst
part of MDEV-28133
bt full - to include args and locals.
set print sevenbit on
- it is more useful to be able to see the exact bytes
(in case something is dumped as a string and not hexadecimal digits)
set print static-members off
- there are many interesting (non-const) static members
set frame-arguments all
- even non-printables are useful to see.
Let's make our bb logs give a little bit more detail on those
hard to reproduce bugs.
Tests on rhel7's gdb-7.6.1-120.el7
mtr detects a forced combination if the command line for a test already
includes all options from this combination. options are stored in a perl
hash as (key,value) pairs.
this breaks if the command line has two options with the same name,
like --plugin-load-add=foo --plugin-load-add=bar, and the combination
forces plugin foo.
In particular, this resulted in warnings when running
federated.federatedx_versioning test
There is a server startup option --gdb a.k.a. --debug-gdb that requests
signals to be set for more convenient debugging. Most notably, SIGINT
(ctrl-c) will not be ignored, and you will be able to interrupt the
execution of the server while GDB is attached to it.
When we are debugging, the signal handlers that would normally display
a terse stack trace are useless.
When we are debugging with rr, the signal handlers may interfere with
a SIGKILL that could be sent to the process by the environment, and ruin
the rr replay trace, due to a Linux kernel bug
https://lkml.org/lkml/2021/10/31/311
To be able to diagnose bugs in kill+restart tests, we may really need
both a trace before the SIGKILL and a trace of the failure after a
subsequent server startup. So, we had better avoid hitting the problem
by simply not installing those signal handlers.
Create minidump when server fails to shutdown. If process is being
debugged, cause a debug break.
Moves some code which is part of safe_kill into mysys, as both safe_kill,
and mysqltest produce minidumps on different timeouts.
Small cleanup in wait_until_dead() - replace inefficient loop with a single
wait.
if all options from a combination from the combinations file are already
present in the server's list of options, then don't try to run tests
in other combinations from this file.
old behavior was: if at least one option from a combination is
already present in the list...
part II
need to tell SafeProcess not to collect the exited mysqld
in sleep_until_file_created(), so that it would be found in the
later wait_any_timeout() in run_testcase()
Removed a strange condition in SafeProcess::wait_one()
that treated return value of -1 from waitpid() as "process exists"
instead of as "no such child process" (see `perldoc -f waitpid`)
expect file is always removed before starting a server.
So if it exists here, it means the server started successfully,
mysqltest continued executing the test, created a new expect file,
and shut down the server. All while we were waiting for the server
to start.
In other words, if the expect file exists, the server did actually start.
Even if it isn't running now.
This fixes occasional failures of innodb.log_corruption (in 10.6)
Add fixed for tests mysqld--help,aix.rdiff and sysvars_server_notembedded,aix.rdiff
AIX couldn't compile in embedded mode so leaving sysvars_server_embedded
for later (if required).
Test times when using --valgrind are now 4 hours and server start/shutdown
time 180 seconds.
The whole test suite time is caped at 1 day instead of 7 days
Reviewer: Monty
As a part of this MDEV following changes were made:
1) Mariadb named executables used instead of mysql named executables in scripts
2) renamed mysql-test-run and mysql-stress-test to mariadb-test-run and
mariadb-stress-test and created a symlink.
