Requiring contiguous buffers removes the need to use mxs::Buffer which
also removes the need to check for buffer boundaries.
Converted all the functions used by get_canonical into `static inline` so
that the compiler knows it can inline them. A few of them weren't `static`
which made the calls to the functions unnecessarily expensive.
The backslash was added instead of assigned. Since the value stored at
that position is always a null byte, assignment and addition would result
in the same outcome.
The help output of all the list and show commands now explains what each
field in the output table means. The generated table will be added at the
end of the help output.
The descriptions table looks like this:
Field Description
----- -----------
Version MaxScale version
Commit MaxScale commit ID
Started At Time when MaxScale was started
Activated At Time when MaxScale left passive mode
Uptime Time MaxScale has been running
Parameters Global MaxScale parameters
The fields are now defined separately and no longer use the object keys as
the names of the values. This makes it clearer as to what the field
definition actually is. Following commits will add a description key into
each object that makes it possible to easily build help output.
Cherry-picked 12e6ada259c38d535003c068a49bc525c33830d8 into 2.3.
Since the maxctrl build process uses add_custom_command, we must
explicitly list the sources that it depends on. With this change, maxctrl
is rebuild whenever the sources change.
So as to allow the change date to be update at each maintenance
release, we need to have a separate license for each minor release.
In each minor branch there will then be a LICENCE.TXT symbolic link
that points to the actual file.
The client count was incremented before authentication was complete, and
should be decremented if it fails. Otherwise service connection limit can
be easily reached.
By printing the stacktrace in one log message, it prevents it from
interleaving with other messages. This happens on busy systems and makes
crash analysis harder.
RENAME TABLE is now fully supported and works as expected. With the fix to
table versioning, the new table name will receive the latest version
number.
The table versions are now stored in memory and are only resolved on
startup. This simplifies things and removes the need to know where the
data is stored as that information is not available to the Rpl class.
This adds preliminary support for renaming tables. There is still a
problem where the table version will always be set to 1 on a rename. This
should not be done and the version should be set to the largest value that
ever was for that table.
When lazy_connect is enabled and the first query is `SET autocommit=0`, a
master connection can be created. If it is, then the m_current_master
pointer must also be updated.
Also fixed the case where a failure to connect to one slave would cause
the connection attempts to stop too early.
TIMESTAMP2, DATETIME2 and TIME2 values with decimal parts are now
correctly converted into their string forms. Previously the decimal part
was ignored but most of the code required to extract it was in place.
The unsigned integers that would previously be interpreted as negative
values are now correctly converted into their corresponding avro
values. Due to a limitation in the Avro file format, 64-bit unsigned
integers cannot be represented in their unsigned form.
Since both the signed and unsigned versions of a 32-bit integer cannot fit
into a single Avro int, the type for these was changed to long. This is a
backwards incompatible change which means files generated with older
versions will not convert unsigned values correctly.
The unsignedness of a column is now retained in the Column type as well as
the JSON schema. This allows correct conversion of unsigned integer types
which will be done in a later commit.
The purpose is to recognize e.g. /_utf8mb4 0xD091D092D093/ as
a valid string. The rule actually accepts /id integer/, but in
case the statement is something else but an '_' immediately
followed by a character set, followed by a hex number, it will
be rejected by the server so no harm done.
During the build first binary packages are generated and copied into
'pre-repo' direcotory. Then binary repository is created and next
step is to copy repository into final directory according agreed
binary repo sirectories structure. After it temparal direcotries
are not needed.
