68a1ee9960 branches/zip: Add some Doxygen comments for many structs, typedefs,
#defines and global variables.  Many are still missing.

11ff89d994 branches/zip: Add @file comments, and convert decorative
/*********************************
comments to Doxygen /** style like this:
/*****************************//**

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

e49dee377b branches/zip: Convert the function comments to Doxygen format.
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.

d9317eb699 branches/zip: Non-functional change:
buf_block_dbg_add_level(block, level): Define as an empty macro when
UNIV_SYNC_DEBUG is not defined.  Remove #ifdef UNIV_SYNC_DEBUG around
all invocations.

6557ba5342 branches/zip: Silence most GCC 4.2.1 warnings about const pointers.
For some reason, GCC 4.2.1 ignores casts (for removing constness)
in calls to inline functions.

page_align(), ut_align_down(): Make the parameter const void*, but still
return a non-const pointer.  This is ugly, but these functions cannot be
replaced with a const-preserving macro in a portable way, given that
the pointer argument is not always pointing to bytes.

buf_block_get_page_zip(): Implement as a const-preserving macro.

buf_frame_get_page_zip(), buf_block_align(): Add const qualifiers.

lock_rec_get_prev(): Silence GCC 4.2.1 warnings.

mlog_write_initial_log_record(), mlog_write_initial_log_record_fast(),
mtr_memo_contains(): Add const qualifier to the pointer.

page_header_get_ptr(): Rewrite as page_header_get_offs(), and
implement as a macro that calls this function.

fff329cd3d branches/zip: Remove the fil_space_get_zip_size() call from
buf_page_get_gen().  This saves one mutex operation per block request.

buf_page_get_gen(), various macros and functions: Add parameter zip_size.

btr_node_ptr_get_child(): Add parameter index.

fil_space_get_latch(): Add optional output parameter zip_size.

fil_space_get_zip_size(): Return 0 for space id==0, because the
system tablespace is never compressed.

fsp_header_init(): Remove the parameter zip_size.

ibuf_free_excess_pages(): Remove the parameter zip_size.

trx_rseg_t, trx_undo_t: Add field zip_size.

xdes_lst_get_next(): Remove, unused.

8562e752bc branches/zip: Remove some more buf_block_align() calls.
btr_cur_t: Move page_block to page_cur_t::block.

page_cur_get_block(), page_cur_get_page_zip(): New functions.

page_cur_position(): Add parameter block.

Remove many page_zip parameters, now that there is page_cur_get_page_zip().
Replace some page, page_zip parameters with block.

Add some const qualifiers to function parameters and remove casts.

PAGE_HEAP_NO_INFIMUM, PAGE_HEAP_NO_SUPREMUM, PAGE_HEAP_NO_USER_LOW:
New constants.

Replace some cursor code in low-level diagnostic functions with
direct management of rec, because buf_block_t::buf_fix_count may be 0
when the functions are called, and debug assertions would fail.

e8a779e73e branches/zip: Remove the casts introduced in r920 and r925. Replace the
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.

c659b59a5d branches/zip: Eliminate many buf_block_align() calls.

buf_block_t*.

ibuf_update_free_bits_if_full(), btr_leaf_page_release(),
buf_page_make_young(): Replace page_t with buf_block_t.

btr_page_alloc(), buf_page_get_release_on_io(), buf_page_get_gen(),
buf_page_create(), fseg_create(), fseg_create_general(): Return buf_block_t.

buf_page_get_known_nowait(): Expect buf_block_t instead of buf_frame_t.

buf_frame_get_newest_modification(): Replace with
buf_block_get_newest_modification().

buf_page_dbg_add_level(): Replace with buf_block_dbg_add_level().

buf_block_get_zip_size(): New function.
