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).

branches/5.1: Fix a bug in multi-table semi-consistent reads.
Remember the acquired record locks per table handle (row_prebuilt_t)
rather than per transaction (trx_t), so that unlock_row should successfully
unlock all non-matching rows in multi-table operations.
This deficiency was found while investigating Bug #39320.

an index or table. We have to skip this check when loading table definitions
from the data dictionary, because we could otherwise refuse to load old
tables (even uncompressed ones). This addresses Issue #119.
The first "row too large" check was implemented in MySQL 5.0.3
to address MySQL Bug #5682. In the InnoDB Plugin 1.0.2, a more
accurate check was implemented in innodb_strict_mode. We now
make the check unconditional.
dict_create_index_step(): Pass strict=TRUE to dict_index_add_to_cache().
trx_is_strict(), thd_is_strict(): Remove.
innodb-zip.test: Test in innodb_strict_mode=OFF.
innodb_bug36169.test: Ensure that none of the tables can be created.

1. We add a vector of locks to trx_t. This array contains the autoinc
locks granted to a transaction. There is one per table.
2. We enforce releasing of these locks in the reverse order from the
one in which they are acquired. The assumption is that since the
AUTOINC locks are statement level locks. Nested statements introduced
by triggers are stacked it should hold.
There was some cleanup done to the vector code too by adding const and
some new functions. Rename dict_table_t::auto_inc_lock to autoinc_lock.

the maximum record size will never exceed the B-tree page size limit.
For uncompressed tables, there should always be enough space for two
records in an empty B-tree page. For compressed tables, there should
be enough space for storing two node pointer records or one data
record in an empty page in uncompressed format.
dict_build_table_def_step(): Remove the inaccurate check for table row
size.
dict_index_too_big_for_tree(): New function: check if the index
records would be too big for a B-tree page.
dict_index_add_to_cache(): Add the parameter "strict". Invoke
dict_index_too_big_for_tree() if it is set.
trx_is_strict(), thd_is_strict(): New functions, for determining if
innodb_strict_mode is enabled for the current transaction.
dict_create_index_step(): Pass the new parameter strict of
dict_index_add_to_cache() as trx_is_strict(trx). All other callers
pass it as FALSE.
innodb.test: Enable innodb_strict_mode before attempting to create a
table with a too big record size.
innodb-zip.test: Remove the test of inserting random data. Add tests
for checking that the maximum record lengths are enforced at table
creation time.
in *.h files, so that the function signatures in the *.h and *.c files fully
match each other.
ut_dulint_sort(): Add a UNIV_INTERN qualifier also to the function definition.
creating indexes. Lock the user table inside the user transaction.
enum trx_dict_op: Remove TRX_OP_INDEX_MAY_WAIT.
ha_innobase::add_index(): Lock the user tables within prebuilt->trx.
Commit the data dictionary transaction before creating indexes.
ha_innobase::final_drop_index(): Lock the user table within prebuilt->trx.
for dropping the index trees, and set the dictionary operation flag, similar
to what ha_innobase::add_index() does. This should ensure correct crash
recovery.
recovered transactions from new ones. Until r1594, they were distinguished
by trx->sess == NULL.
trx_t: Add the bitfield is_recovered.
trx_lists_init_at_db_start(): Set trx->is_recovered.
trx_create(): Initialize trx->is_recovered = 0.
trx_print(): Display information about trx->is_recovered.
trx_rollback_or_clean_all_without_sess(): Skip new transactions.
Protect all accesses of trx_sys->trx_list with kernel_mutex.
trx_roll_crash_recv_trx, trx_roll_max_undo_no, trx_roll_progress_printed_pct:
Made these variables static.
enum trx_dict_op: dictionary operation modes
trx_get_dict_operation(), trx_set_dict_operation(): Accessors for
trx->dict_operation.
lock_table_enqueue_waiting(), lock_rec_enqueue_waiting(): Do not complain
about lock waits if the dictionary mode is TRX_DICT_OP_INDEX_MAY_WAIT.
row_merge_lock_table(): Remove the work-around for avoiding the warning
in lock_table_enqueue_waiting().
trx_undo_mark_as_dict_operation(): Do not write trx->table_id to the
undo log unless the dict_operation is TRX_DICT_OP_TABLE.
ha_innobase::add_index(): Set the dict_operation mode initially to
TRX_DICT_OP_INDEX_MAY_WAIT, then lock the table exclusively, and set the
mode to TRX_DICT_OP_INDEX, and optionally to TRX_DICT_OP_TABLE when
creating a temporary table.
trx_t: Remove dict_undo_list and dict_redo_list.
innobase_create_temporary_tablename(): Replace TEMP_TABLE_PREFIX with
a table name suffix "#1" or "#2". In this way, the user can restore
precious data, should anything go wrong. It is possible to reach an
inconsistent state, because the creation, deletion and renaming of
single-table tablespaces are not transactional.
ut_print_namel(), fil_make_ibd_name(), innobase_rename_table(): Remove
the special treatment of TEMP_TABLE_PREFIX.
Introduce TEMP_INDEX_PREFIX == 0xff for temporary indexes. This byte
cannot occur in index names since MySQL 4.1. However, it might have
been possible to use this byte in MySQL 4.0.
recv_recovery_from_checkpoint_finish(): Call the new function
row_merge_drop_temp_indexes(), to drop all indexes whose name starts
with the byte 0xff.
row_merge_rename_indexes(): Renamed from row_merge_rename_index().
Remove the parameter "index".
row_drop_table_for_mysql(): Unconditionally call trx_commit_for_mysql().
row_drop_table_for_mysql_no_commit(): Correct the function commit,
based on the corrected comment of row_drop_table_for_mysql(). Rely on
table->to_be_dropped instead of TEMP_TABLE_PREFIX.
ha_innobase::add_index(): Simplify the control flow.
trx_t: Change the type of error_info from void* to const dict_index_t*.
trx_get_error_info(): Add const qualifier to trx_t*. Make this an
inline function.

trx_rollback_active(): Split from trx_rollback_or_clean_all_without_sess().
row_undo_dictionary(): Do not return a value. Assert that all operations
succeed.
row_merge_drop_index(): Remove bogus comment about void return value.
trx_dummy_sess: Move the declaration from trx0roll.h to trx0trx.h,
because the variable is defined in trx0trx.c.
now that all of InnoDB code is built from a single Makefile and it should
not be possible to build the modules with mutually incompatible options.
#define INSIDE_HA_INNOBASE_CC: Remove.
srv_sizeof_trx_t_in_ha_innodb_cc: Remove.
dict_table_get_low_noninlined(): Remove. This function was unused.
Remove all _noninline functions. Remove the _noninline suffix from
all function calls in ha_innodb.cc.
