| UNIV_INLINE void mlog_catenate_ulint | ( | mtr_t * | mtr, |
| ulint | val, | ||
| ulint | type | ||
| ) |
Catenates 1 - 4 bytes to the mtr log. The value is not compressed.
- Parameters
-
mtr in: mtr val in: value to write type in: MLOG_1BYTE, MLOG_2BYTES, MLOG_4BYTES
| UNIV_INLINE void mlog_catenate_ulint_compressed | ( | mtr_t * | mtr, |
| ulint | val | ||
| ) |
Catenates a compressed ulint to mlog.
- Parameters
-
mtr in: mtr val in: value to write
| UNIV_INLINE void mlog_catenate_ull_compressed | ( | mtr_t * | mtr, |
| ib_uint64_t | val | ||
| ) |
Catenates a compressed 64-bit integer to mlog.
- Parameters
-
mtr in: mtr val in: value to write
| UNIV_INLINE void mlog_close | ( | mtr_t * | mtr, |
| byte * | ptr | ||
| ) |
Closes a buffer opened to mlog.
- Parameters
-
mtr in: mtr ptr in: buffer space from ptr up was not used
| UNIV_INLINE byte* mlog_open | ( | mtr_t * | mtr, |
| ulint | size | ||
| ) |
Opens a buffer to mlog. It must be closed with mlog_close.
- Returns
- buffer, NULL if log mode MTR_LOG_NONE
- Parameters
-
mtr in: mtr size in: buffer size in bytes; MUST be smaller than DYN_ARRAY_DATA_SIZE!
| UNIV_INLINE byte* mlog_write_initial_log_record_fast | ( | const byte * | ptr, |
| byte | type, | ||
| byte * | log_ptr, | ||
| mtr_t * | mtr | ||
| ) |
Writes the initial part of a log record (3..11 bytes). If the implementation of this function is changed, all size parameters to mlog_open() should be adjusted accordingly!
- Returns
- new value of log_ptr
- Parameters
-
ptr in: pointer to (inside) a buffer frame holding the file page where modification is made type in: log item type: MLOG_1BYTE, ... log_ptr in: pointer to mtr log which has been opened mtr in: mtr
| UNIV_INLINE byte* mlog_write_initial_log_record_for_file_op | ( | ulint | type, |
| ulint | space_id, | ||
| ulint | page_no, | ||
| byte * | log_ptr, | ||
| mtr_t * | mtr | ||
| ) |
Writes a log record about an .ibd file create/delete/rename.
- Returns
- new value of log_ptr
- Parameters
-
type in: MLOG_FILE_CREATE, MLOG_FILE_DELETE, or MLOG_FILE_RENAME space_id in: space id, if applicable page_no in: page number (not relevant currently) log_ptr in: pointer to mtr log which has been opened mtr in: mtr
