The help messages are now more descriptive and have usage information in
them. This should help users use the commands without relying on the
online documentation.
When log messages are written with both address and port information, IPv6
addresses can cause confusion if the normal address:port formatting is
used. The RFC 3986 suggests that all IPv6 addresses are expressed as a
bracket enclosed address optionally followed by the port that is separate
from the address by a colon.
In practice, the "all interfaces" address and port number 3306 can be
written in IPv4 numbers-and-dots notation as 0.0.0.0:3306 and in IPv6
notation as [::]:3306. Using the latter format in log messages keeps the
output consistent with all types of addresses.
The details of the standard can be found at the following addresses:
https://www.ietf.org/rfc/rfc3986.txthttps://www.rfc-editor.org/std/std66.txt
Both the listeners and servers now support IPv6 addresses.
The namedserverfilter does not yet use the new structures and needs to be
fixed in a following commit.
The authenticators should have a similar way to print diagnostic
information as filter and routers do. This allows the authenticators to
print the users in their own format.
In the future, all the diagnostic entry points should be changed so that
they return a structure that contains the information in a standard
form. This information can then be formatted in different ways by other
modules.
The order of the servers in the service definition could break the
master_accept_reads functionality.
When the first server defined in the service is a slave, it will always be
picked as the first candidate for reads. The master would only be
considered as a candidate for reads if no previous candidate was
available. For this reason, the master_accept_reads only worked when the
first server in the list was the master.
The Avro C API fails to write bytes of size zero. A workaround is to write
a single zero byte for each NULL field of type bytes.
Also added an option to configure the Avro block size in case very large
records are written.
The rotations of binlogs weren't detected as the file names weren't
compared.
Moved the indexing of the binlogs to the end of the binlog
processing. This way the files can be flushed multiple times before they
are indexed.
The old DATETIME format wasn't processed properly which caused a
corruption of following events.
A BLOB type value could be non-NULL but still have no data. In this case,
the value should be stored as a null Avro value.
Altered the function to assert that the DCB is a backend DCB in addition
to the existing assertions for non-NULL backend reference on function
return.
Move the fetching of the backend reference after the type of the DCB is
inspected in handleError. This removes the need to handle the case where
the returned bref is NULL and the DCB is a client DCB.
They are not particularly useful, they surely are not used
and impose a small cost for every event extracted from the
poll sets.
This commit only removes the maxadmin commands, subsequent
commits will remove the actual code.
The DECIMAL value type is now properly handled in Avrorouter. It is
processed into an Avro double value when before it was ignored and
replaced with a zero integer.
Backported to the 2.0 branch.
There's no point in indexing the file if it hasn't been synced to
disk. Any attempts to index the file will fail if the file still has an
open data block.
Removed unused spinlocks from DCBs, sessions and the MySQL protocol
structs. They were used in a context where only one thread has access to
the structure.
Removed unused member variables from DCBs.
The debug assertion assumes that the table definition is always in the
binlogs. If a binlog row event without a table definition is read, debug
versions would crash even though the situation is acceptable and expected.
The backtick was copied to the field name and converted to an underscore
when the name was transformed into a valid Avro identifier. This caused
one extra character to appear in the field name in the Avro schema files.
