Jonathan Druart 4ae3665ad8 Bug 10611: Use mysql_auto_reconnect instead of ping DBD::Mysql provides a mysql_auto_reconnect flag. Using it avoids the time required to do a $dbh->ping(). Benchmarks: use Modern::Perl; use C4::Context; for ( 1 .. 1000 ) { $dbh = C4::Context->dbh; } * without this patch on a local DB: perl t.pl 0,49s user 0,02s system 98% cpu 0,525 total * without this patch on a remote DB: perl t.pl 0,52s user 0,05s system 1% cpu 37,358 total * with this patch on a local DB: perl t.pl 0,46s user 0,04s system 99% cpu 0,509 total * with this patch on a remote DB: perl t.pl 0,49s user 0,02s system 56% cpu 0,892 total Testing the auto reconnect: use Modern::Perl; use C4::Context; my $ping = $dbh->ping; say $ping; $dbh->disconnect; $ping = $dbh->ping; say $ping; Signed-off-by: Bernardo Gonzalez Kriegel <bgkriegel@gmail.com> Comment: Real improvement. No koha-qa errors prove t/db_dependent/Circulation_issuingrules.t produces no error prove t/db_dependent/Context.t produces no error Test 1) dumped Koha DB, load it on a non-local server 2) run sample script whit and without patch, local and remote use Modern::Perl; use C4::Context; for ( 1 .. 100000 ) { my $dbh = C4::Context->dbh; } Main difference I note is with remote server a) without patch real 0m16.357s user 0m2.592s sys 0m2.132s b) with patch real 0m0.259s user 0m0.240s sys 0m0.012s I think this could be good for DBs placed on remote servers Bug 10611: add a "new" parameter to C4::Context->dbh When dbh->disconnect is called and the mysql_auto_reconnect flag is set, the dbh is not recreated: the old one is used. Adding a new flag, we can now force the C4::Context->dbh method to return a new dbh. Signed-off-by: Bernardo Gonzalez Kriegel <bgkriegel@gmail.com> Bug 10611: Followup: remove useless calls to dbh->disconnect These 3 calls to disconnect are done at the end of the script, they are useless.
