Class used to guarantee copy of cache to file before exiting the

We want to store the thread id:

1127 |
(- as an information for the user when he reads the binlog)
|

1128 |
- if the query uses temporary table: for the slave SQL thread to know to
|
|
1129 |
which master connection the temp table belongs.
|
|
1130 |
Now imagine we (write()) are called by the slave SQL thread (we are
|
|
1131 |
logging a query executed by this thread; the slave runs with
|
|
1132 |
--log-slave-updates). Then this query will be logged with
|
|
1133 |
thread_id=the_thread_id_of_the_SQL_thread. Imagine that 2 temp tables of
|
|
1134 |
the same name were created simultaneously on the master (in the master
|
|
1135 |
binlog you have
|
|
1136 |
CREATE TEMPORARY TABLE t; (thread 1)
|
|
1137 |
CREATE TEMPORARY TABLE t; (thread 2)
|
|
1138 |
...)
|
|
1139 |
then in the slave's binlog there will be
|
|
1140 |
CREATE TEMPORARY TABLE t; (thread_id_of_the_slave_SQL_thread)
|
|
1141 |
CREATE TEMPORARY TABLE t; (thread_id_of_the_slave_SQL_thread)
|
|
1142 |
which is bad (same thread id!).
|
|
1143 |
||
1144 |
To avoid this, we log the thread's thread id EXCEPT for the SQL
|
|
1145 |
slave thread for which we log the original (master's) thread id.
|
|
1146 |
Now this moves the bug: what happens if the thread id on the
|
|
1147 |
master was 10 and when the slave replicates the query, a
|
|
1148 |
connection number 10 is opened by a normal client on the slave,
|
|
1149 |
and updates a temp table of the same name? We get a problem
|
|
1150 |
again. To avoid this, in the handling of temp tables (sql_base.cc)
|
|
1151 |
we use thread_id AND server_id. TODO when this is merged into
|
|
1152 |
4.1: in 4.1, slave_proxy_id has been renamed to pseudo_thread_id
|
|
1153 |
and is a session variable: that's to make mysqlbinlog work with

The problem with this constructor is that the fixed header may have a

1949 |
length different from this version, but we don't know this length as we

|
1950 |
have not read the Format_description_log_event which says it, yet. This

1951 |
length is in the post-header of the event, but we don't know where the

post-header starts.

So this type of event HAS to:

1955 |
- either have the header's length at the beginning (in the header, at a
|
|
1956 |
fixed position which will never be changed), not in the post-header. That

|
1957 |
would make the header be "shifted" compared to other events.
|

1958 |
- or have a header of size LOG_EVENT_MINIMAL_HEADER_LEN (19), in all future
|
|
1959 |
versions, so that we know for sure.

Load_log_event methods
|
|
2215 |
General note about Load_log_event: the binlogging of LOAD DATA INFILE is
|
|
2216 |
going to be changed in 5.0 (or maybe in 5.1; not decided yet).
|
|
2217 |
However, the 5.0 slave could still have to read such events (from a 4.x
|
|
2218 |
master), convert them (which just means maybe expand the header, when 5.0
|
|
2219 |
servers have a UID in events) (remember that whatever is after the header
|
|
2220 |
will be like in 4.x, as this event's format is not modified in 5.0 as we
|
|
2221 |
will use new types of events to log the new LOAD DATA INFILE features).
|
|
2222 |
To be able to read/convert, we just need to not assume that the common
|
|
2223 |
header is of length LOG_EVENT_HEADER_LEN (we must use the description
|
|
2224 |
event).
|
|
2225 |
Note that I (Guilhem) manually tested replication of a big LOAD DATA INFILE
|
|
2226 |
between 3.23 and 5.0, and between 4.0 and 5.0, and it works fine (and the
|
|
2227 |
positions displayed in SHOW SLAVE STATUS then are fine too).

We test replicate_*_db rules. Note that we have already prepared

2633 |
the file to load, even if we are going to ignore and delete it
|
|
2634 |
now. So it is possible that we did a lot of disk writes for
|
|
2635 |
nothing. In other words, a big LOAD DATA INFILE on the master will
|
|
2636 |
still consume a lot of space on the slave (space in the relay log
|
|
2637 |
+ space of temp files: twice the space of the file to load...)
|
|
2638 |
even if it will finally be ignored. TODO: fix this; this can be

|
2639 |
done by testing rules in Create_file_log_event::do_apply_event()

filtering in the I/O thread (more efficient: no disk writes at

all).

Reason: The db stored in binlog events is the same for SET and for

|
2648 |
its companion query. If the SET is ignored because of
|
|
2649 |
db_ok(), the companion query will also be ignored, and if

2650 |
the companion query is ignored in the db_ok() test of
|
|
2651 |
::do_apply_event(), then the companion SET also have so

@page How replication of field metadata works.

660.1.3
by Eric Herman
removed trailing whitespace with simple script: |
4747 |
|
4748 |
When a table map is created, the master first calls
|
|
4749 |
Table_map_log_event::save_field_metadata() which calculates how many
|
|
4750 |
values will be in the field metadata. Only those fields that require the
|
|
4751 |
extra data are added. The method also loops through all of the fields in
|
|
1
by brian
clean slate |
4752 |
the table calling the method Field::save_field_metadata() which returns the
|
4753 |
values for the field that will be saved in the metadata and replicated to
|
|
4754 |
the slave. Once all fields have been processed, the table map is written to
|
|
4755 |
the binlog adding the size of the field metadata and the field metadata to
|
|
4756 |
the end of the body of the table map.
|
|
4757 |
||
660.1.3
by Eric Herman
removed trailing whitespace with simple script: |
4758 |
When a table map is read on the slave, the field metadata is read from the
|
4759 |
table map and passed to the table_def class constructor which saves the
|
|
4760 |
field metadata from the table map into an array based on the type of the
|
|
4761 |
field. Field metadata values not present (those fields that do not use extra
|
|
4762 |
data) in the table map are initialized as zero (0). The array size is the
|
|

4763 |
same as the columns for the table on the slave.

We may want to consider changing the encoding of the information.

660.1.3
by Eric Herman
removed trailing whitespace with simple script: |
4787 |
Currently, the code attempts to minimize the number of bytes written to
|
4788 |
the tablemap. There are at least two other alternatives; 1) using
|
|
1
by brian
clean slate |
4789 |
net_store_length() to store the data allowing it to choose the number of
|
660.1.3
by Eric Herman
removed trailing whitespace with simple script: |
4790 |
bytes that are appropriate thereby making the code much easier to
|
1
by brian
clean slate |
4791 |
maintain (only 1 place to change the encoding), or 2) use a fixed number
|
4792 |
of bytes for each field. The problem with option 1 is that net_store_length()
|
|
4793 |
will use one byte if the value < 251, but 3 bytes if it is > 250. Thus,
|
|
4794 |
for fields like CHAR which can be no larger than 255 characters, the method
|
|
4795 |
will use 3 bytes when the value is > 250. Further, every value that is
|
|
4796 |
encoded using 2 parts (e.g., pack_length, field_length) will be numerically
|
|
4797 |
> 250 therefore will use 3 bytes for eah value. The problem with option 2
|
|
4798 |
is less wasteful for space but does waste 1 byte for every field that does
