Gw.h contained a fair amount of obsolete function declarations,
duplicate declarations of functions declared in utils.h and
declarations of functions that conceptually are similar to those
in utils.h.
The obsolete and duplicate ones were removed and all but one of
the remaining moved to utils.h. Correspondingly the implementation
was moved from gw_utils.c to utils.c.
The one remaining function - gw_daemonize() - is not really worthy
of a file of its own, so that is to be moved to gateway.c after which
gw_utils.c can be removed.
Gw.h still contains defines that are duplicated in
maxscale/protocol/mysql.h. The ones in gw.h are to be removed. It
appears that the entire gw.h will disappear.
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.
Made the packet sequence number handling automatic so that it always uses
the correct one.
All functions now have documentation in them. Cleaned up code and added
comments to GSSAPI code.
- 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.
- 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.
The purpose of this file is to provide a header that *must* be included
first (that is, also before any system headers) by all other headers. On
the one hand this file provides a place where compilation environment
dependent things can be defined, and, on the other hand, a place where
things can be redefined globally, should that be necessary for whatever
reason. It further provides a place where constants applicable across
the line can be defined.
- 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.
- as command types in protocol modules (standard routing or session change routing)
- to write back the data from backend (discard multiple backends ouput)
gwbuf struct
dcb struct
This int field will hold the last command executed or sent to backend.
It will be 0 for most cases, setting it with a different value could help route differently the data from backend to client or some custom error messages.
different offsets for different gwbufs
Updated monitor to better handle maste/slave replication environments
Split MASTER and SERVER bits in the erver bitmask so that we canhave more states, MASTER, SLAVE and NOT IN REPLICATION
Updates to the read write splitter for routing commands to all nodes, diagnostic output and fixes to the algorithm to pick up a master and slave connection
