Hi,
I've downloaded the new 3.1.6 and I was going to replace our 3.1.5
version when I encountered a big performance drop with htsearch. The
database was 3.1.5, and I had the two htsearch version
together. Difference was systematic (3.1.6 more than 10 time
slower). This reminded me of the "backlink_factor" effect. So I looked
something in the code were the document database would be called for each
match. I think I find where.
In display.cc there is this test:
// New check added on whether or not we need to check date ranges - MG
if (date_factor != 0.0 || backlink_factor != 0.0 || typ != SortByScore
|| timet_startdate > 0 || enddate.tm_year < endoftime->tm_year)
If there is no date specified, the code inside should not be executed, but
it is! I changed the test to this:
// New check added on whether or not we need to check date ranges - MG
if (date_factor != 0.0 || backlink_factor != 0.0 || typ != SortByScore
|| timet_startdate > 0 || timet_enddate < eternity)
according to the "no date given" case and it works. Speed is as it was
with 3.1.5.
So I do not fully understand this "date" stuff and in our case I don't
thing we will use it.
But if indeed the test is wrong, it should be corrected (maybe not with
what I did).
I had also to change the Makefile.config.in to make it compile on our old
SGI plateform (SGI Irix 6.3 with the SGI Compiler):
265# diff -c Makefile.config.in.ORIG Makefile.config.in

Without that, make stop with an error in htlib because it cannot resolve
"alloca". The @DEFS@ just have the HAVE_CONFIG define.
Thanks!
