[htdig-dev] Changes to mp_alloc.c to prevent execesive recursion cause larger size

[Neal R. <ne...@ri...>]

Hey all,
	I'm seeing a bad effect of the recent changes to mp_alloc.c.  The
db.word.db is growing excessively.

	If I replace mp_alloc.c with a previous version (Revision 1.2 via
CVS), this issue goes away.  It is necessary to comment out a variable in
db.h, DB2_db.cc & WordDB.cc.

	Note that it does not cause DB corruption as htdump produces
EXACTLY equivalent text dumps of the db.word.db before and after the
change.

	If you Define DEBUG_CMPR in ml_cmpr.cc you notice during the run
that the memory pages seem to be flushed to disk a LOT more often.

	Could someone else test this and reply?

Example:
 77824 Jul 14 18:45 db.words.db   (old mp_alloc.c)
184320 Jul 14 18:24 db.words.db   (new mp_alloc.c)

And the size difference gets much worse the more pages you index.

Thanks!
