In a subsequent change, the includes of server/core/*.c will be
cleaned up, and if there is a common set of include files, needed
by most, then a server/core/maxscale/core.h that includes those
will be introduced.
MAX_BUFFER_SIZE, which is used for limiting the amount of the data
read from a socket renamed to MXS_MAX_NW_READ_BUFFER_SIZE and moved
from gw.h to limits.h.
Consider removing altogether. Difficult to justify since non-blocking
reads are used and the amount of available data is known.
When the readwritesplit can't locate the master server when it's checking
the list of available servers, it logs an error if the original master
reference isn't in a valid state. This error should only be logged if the
server is in use but in an unexpected state.
The general purpose stuff in skygw_utils.h was moved to utils.h
and the corresponding implementation from skygw_utils.cc to utils.c.
Includes updated accordingly.
Skygw_utils.h is now only used by log_manager and by mlist, which
is only used by log_manager. Consequently, skygw_utils.h was moved
to server/maxscale.
Utils.h needs a separate overhaul.
- STRERROR_BUFLEN moved to cdefs.h and renamed to MXS_STRERROR_BUFLEN.
Better would be to provide a 'const char* mxs_strerror(int errno)'
that would have a thread specific buffer for the error message.
- MIN and MAX also moved to defs.h as MXS_MIN and MXS_MAX.
- Now only mlist.h of the headers depend upon skygw_utils.h.
When a hole is detected while receiving events an ignorable event is
written in maxscale binlog. Such event is not sent ti slave servers.
Maxbinlogcheck can now check encrypted binlog files without decrypting
them
- All now include maxscale/cdefs.h as the very first file.
- MXS_[BEGIN|END]_DECLS added to all C-headers.
Strictly speaking not necessary for private headers, but
does not hurt either.
- Include guards moved to the very top of the file.
- #pragma once added.
- Headers now to be included as <maxscale/xyz.h>
- First step, no cleanup of headers has been made. Only moving
from one place to another + necessary modifications.
Authenticators now have a similar mechanism to the `router_options`
parameter which enables configurable authentication.
The authenticators also have a new initialize entry point which is similar
to the createInstance entry point of the filters and routers. The value of
`authenticator_options` is passed as a parameter to this function. The
return vaulue of the `initialize` entry point is passed to the `create`
entry point.
Events saved and read have 15 bytes of header XORed with IV.
Partial events are still not handled.
Next implementation will encrypt the whole event instead of 15 bytes XOR
Encryption Context and Encryption Setup structures have been added to
ROUTER_INSTANCE
Replication doesn’t start if binlog file has START_ENCRYPTION_EVENT but
router_option ‘encrypt_binlog’ is Off
The backend reference states should be cleared when a reconnection attempt
is made. Should the creation of a new DCB succeed, the backend should no
longer be closed.
Addition of START_ENCRYPTION_EVENT when encrypt_binlog=1 in Binlog
Server option.
Event is not sent to any slave.
MaxBinlogCheck understands the new event added in MariaDB 10.1.7: the
number of events = 164 as reported by FormatDescriptionEvent
An IGNORABLE event is added into binlog when a gap between two events
is detected.
New routines create and write special events.
Special events are not sent to slaves.
