This conversion was performed by the following command:
perl -i -e 'while(<ARGV>){if (m|^/\*{30}\**$|) {
s|\*{4}$|//**| if ++$com>1; $_ .= "\@file $ARGV\n" if $com==2}
print; if(eof){$.=0;undef $com}}' */*[ch] include/univ.i
This patch was created by running the following commands:
for i in */*[ch]; do doxygenify.pl $i; done
perl -i -pe 's#\*{3} \*/$#****/#' */*[ch]
where doxygenify.pl is
https://svn.innodb.com/svn/misc/trunk/tools/doxygenify.pl r510
Verified the consistency as follows:
(0) not too many /* in: */ or /* out: */ comments left in the code:
grep -l '/\*\s*\(in\|out\)[,:/]' */*[ch]
(1) no difference when ignoring blank lines, after stripping all
C90-style /* comments */, including multi-line ones, before and after
applying this patch:
perl -i -e 'undef $/;while(<ARGV>){s#/\*(.*?)\*/##gs;print}' */*[ch]
diff -I'^\s*$' --exclude .svn -ru TREE1 TREE2
(2) after stripping @return comments and !<, generated a diff and omitted
the hunks where /* out: */ function return comments were removed:
perl -i -e'undef $/;while(<ARGV>){s#!<##g;s#\n\@return\t.*?\*/# \*/#gs;print}'\
*/*[ch]
svn diff|
perl -e 'undef $/;$_=<>;s#\n-\s*/\* out[:,]([^\n]*?)(\n-[^\n]*?)*\*/##gs;print'
Some unintended changes were left. These will be removed in a
subsequent patch.
and undo_no_t. Each type is still defined as dulint.
This is an initial step towards replacing dulint with a 64-bit data type.
Because modern compilers have no trouble supporting 64-bit arithmetics
even on 32-bit targets, the dulint struct is a relic that should go.
The last remaining major use of dulint is dictionary IDs
(table, index, and row ids).

[Step 16/28]
fix the bugs introduced in r1591.
row_rec_to_index_entry_low(): Clear "n_ext". Do not allow it to be NULL.
Add const qualifier to dict_index_t*.
row_rec_to_index_entry(): Add the parameters "offsets" and "n_ext".
btr_cur_optimistic_update(): Add an assertion that there are no externally
stored columns. Remove the unreachable call to btr_cur_unmark_extern_fields()
and the preceding unnecessary call to rec_get_offsets().
btr_push_update_extern_fields(): Remove the parameters index, offsets.
Only report the additional externally stored columns of the update vector.
row_build(), trx_undo_rec_get_partial_row(): Flag externally stored columns
also with dfield_set_ext().
rec_copy_prefix_to_dtuple(): Assert that there are no externally stored
columns in the prefix.
row_build_row_ref(): Note and assert that the index is a secondary index,
and assert that there are no externally stored columns.
row_build_row_ref_fast(): Assert that there are no externally stored columns.
rec_offs_get_n_alloc(): Expose the function.
row_build_row_ref_in_tuple(): Assert that there are no externally stored
columns in a record of a secondary index.
row_build_row_ref_from_row(): Assert that there are no externally stored
columns.
row_upd_check_references_constraints(): Add the parameter offsets, to
avoid a redundant call to rec_get_offsets().
row_upd_del_mark_clust_rec(): Add the parameter offsets. Remove
duplicated code.
row_ins_index_entry_set_vals(): Copy the external storage flag.
sel_pop_prefetched_row(): Assert that there are no externally stored
columns.
row_scan_and_check_index(): Copy offsets to a temporary heap across
the invocation of row_rec_to_index_entry().
accessors returning pointers with macros that preserve const qualifiers.
In UNIV_DEBUG builds, retain the accessors and cast away constness there.
dfield_get_type(), dfield_get_data(), dtuple_get_nth_field(),
dict_table_get_nth_col(), dict_table_get_sys_col(): Implement as macro
unless #ifdef UNIV_DEBUG.
rec_get_nth_field(): Replace with rec_get_nth_field_offs() that does not
do pointer arithmetics. Implement rec_get_nth_field() as a macro.
and modify some functions to return const pointers. Add const qualifiers
to local variable declarations or casts to remove the const qualifier
in those places where write access is needed.
of clustered indexes. Previously, parts of the code assumed that these
columns would exist on all leaf pages. Simplify the update-in-place of
these columns.
Add inline function dict_index_is_clust() to replace all tests
index->type & DICT_CLUSTERED.
Remove the redo log entry types MLOG_ZIP_WRITE_TRX_ID and
MLOG_ZIP_WRITE_ROLL_PTR, because the modifications to these columns
are covered by logical logging.
Fuse page_zip_write_trx_id() and page_zip_write_roll_ptr() into
page_zip_write_trx_id_and_roll_ptr().
page_zip_dir_add_slot(), page_zip_available(): Add flag "is_clustered",
so that no space will be reserved for TRX_ID and ROLL_PTR on leaf pages
of secondary indexes.
page_zip_apply_log(): Flag an error when val==0 is encoded with two bytes.
page_zip_write_rec(): Add debug assertions that there is enough space
available for the entry before copying the data bytes of the record.
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.
