/*
General philosophy of InnoDB redo-logs:
1) Every change to a contents of a data page must be done
through mtr, which in mtr_commit() writes log records
to the InnoDB redo log.
2) Normally these changes are performed using a mlog_write_ulint()
or similar function.
3) In some page level operations only a code number of a
c-function and its parameters are written to the log to
reduce the size of the log.
3a) You should not add parameters to these kind of functions
(e.g. trx_undo_header_create(), trx_undo_insert_header_reuse())
3b) You should not add such functionality which either change
working when compared with the old or are dependent on data
outside of the page. These kind of functions should implement
self-contained page transformation and it should be unchanged
if you don't have very essential reasons to change log
semantics or format.

1 MySQL supports a number of column types in several categories: numeric types, date and time types, and string (character) types. This chapter first gives an overview of these column types, and then provides a more detailed description of the properties of the types in each category, and a summary of the column type storage requirements. The overview is intentionally brief. The more detailed descriptions should be consulted for additional information about particular column types, such as the allowable formats in which you can specify values.
2 All arithmetic is done using signed BIGINT or DOUBLE values, so you should not use unsigned big integers larger than 9223372036854775807 (63 bits) except with bit functions! If you do that, some of the last digits in the result may be wrong because of rounding errors when converting a BIGINT value to a DOUBLE.
3 A floating-point number. p represents the precision. It can be from 0 to 24 for a single-precision floating-point number and from 25 to 53 for a double-precision floating-point number. These types are like the FLOAT and DOUBLE types described immediately following. FLOAT(p) has the same range as the corresponding FLOAT and DOUBLE types, but the display size and number of decimals are undefined.
