df85f7287c branches/zip: Minor fixes
trx-undo_prev_version_build(): Pass offsets==NULL to
rec_set_field_extern_bits().

rec_set_field_extern_bits(), rec_set_field_extern_bits_new():
Accept offsets==NULL.

row_upd_rec_in_place(): Remove the bogus comment that the function
would only be invoked on a clustered index.  Remove the related
debug assertion.

2e08171ada branches/zip: Bug fixes for BLOB handling. At least one bug remains:
page_zip_dir_delete() will need to handle BLOBs.

rec_set_field_extern_bits(), rec_set_field_extern_bits_new():
Add parameter offsets.

rec_offs_set_nth_extern(): New function to set an extern bit in offsets.
This will be called when an extern bit is set in a record.

page_cur_rec_insert(), page_cur_insert_rec_low(): Document that the
parameter "offsets" is in/out.

page_zip_dir_delete(): Note that the array of BLOB pointers will need
to be shifted.

page0zip.ic: Document the entry type for clearing a record.

page_zip_available(): Add parameter "index".  Remove parameters
"is_leaf" and "is_clustered".

page_zip_get_trailer_len(): New function for computing the trailer length
of the compressed page.

page_zip_apply_log(): Implement the modification log entry type for
clearing the data bytes of a record.

page_zip_decompress(): Initialize n_blobs when actually copying the
BLOB pointers to place.

page_zip_validate(): Add diagnostic messages for failures.  Check
also m_start, m_end, and n_blobs.

page_zip_write_blob_ptr(): Add page_zip_validate() assertion.

748da76442 branches/zip: Bug fixes
rec_get_offsets_reverse(): Calculate extra_size correctly.

page_zip_apply_log(): Fix an off-by-one error in comparison.
Replace heap_status with hs where possible.
Increment the heap_no in heap_status correctly.

page_zip_decompress(): Eliminate the local variable "err".
Check for Z_STREAM_END only at the start of a record, so that
incomplete records will always be detected.

page_zip_write_rec(): Calculate the address of "storage" in the
same way as elsewhere.  Add TODO comments regarding the handling
of the uncompressed fields (BLOB pointers, trx_id, and roll_ptr).

c04ddfef05 branches/zip: Try to synchronize the updates of uncompressed and
compressed pages.

btr_root_raise_and_insert(): Distinguish root_page_zip and new_page_zip.

btr_cur_set_ownership_of_extern_field(): Do not log the write on the
uncompressed page if it will be logged for page_zip.

lock_rec_insert_check_and_lock(), lock_sec_rec_modify_check_and_lock():
Update the max_trx_id field also on the compressed page.

mlog_write_ulint(): Add UNIV_UNLIKELY hints.  Remove trailing white space.

mlog_log_string(): Remove trailing white space.

rec_set_field_extern_bits(): Remove parameter mtr, as the write will either
occur in the heap, or it will be logged at a higher level.

recv_parse_or_apply_log_rec_body(),
page_zip_write_header(): Add log record type MLOG_ZIP_WRITE_HEADER.

page_header_set_field(): Pass mtr=NULL to page_zip_write_header().

page_header_reset_last_insert(): Pass mtr to page_zip_write_header().

btr_page_set_index_id(), btr_page_set_level(),
btr_page_set_next(), btr_page_set_prev(): Pass mtr to page_zip_write_header().

row_upd_rec_sys_fields(): Pass mtr=NULL to page_zip_write_trx_id() and
page_zip_write_roll_ptr(), since the write will be logged at a higher level.

page_zip_write_header(): Add parameter mtr.
page_zip_write_header_log(): New function.

Remove rec_set_nth_field_extern_bit().
Make rec_set_nth_field_extern_bit_old() static.
Rename rec_set_nth_field_extern_bit_new()
to rec_set_field_extern_bits_new() and make it static.

row_ins_index_entry_low(): Remove bogus TODO comment.

062c64e87e branches/zip: Prepare for in-place updates of B-tree node pointers,
BLOB pointers, trx_id, and roll_ptr.

btr_empty(), btr_create(), page_create(): Add parameter "index", as some
index information will be encoded on the compressed page.

Define REC_NODE_PTR_SIZE as 4.

Allow btr_page_reorganize() and btr_page_reorganize_low() to fail.

Define the error code DB_ZIP_OVERFLOW.

Make row_ins_index_entry_low() static.

page0zip: Encode the index, log reorganized records, and store uncompressed
fields separately from the compressed data stream.
