Simplify DBIHacks signatures

The cross-polination of $attrs and various subparts is becoming a nightmare
to maintain. Straighten up most ::DBIHacks to pass stuff around as a single
$attrs bag (no functional changes, this is a temp-stage cleanup)

The idea is to prepare for an rsattrs object (later on all we will need to
do is replace the hash-grabs with methods, but this requires much more
thought and design, small steps)

Affected signatures in :DBIHacks:
_prune_unused_joins()
_resolve_aliastypes_from_select_args()
_adjust_select_args_for_complex_prefetch()
_extract_fixed_condition_columns()

Not touching to facilitate easier DQ merge (TODO in a sense):
_order_by_is_stable()
_main_source_order_by_portion_is_stable()

11 years agoMany improvements of bigint handling across various DBD::SQLite versions
Peter Rabbitson [Tue, 8 Oct 2013 22:51:25 +0000]
Many improvements of bigint handling across various DBD::SQLite versions

This started as a patch by ilmari to bind all integers as SQL_BIGINT
as opposed to SQL_INTEGER. While this change itself worked fine, further
testing revealed we never actually bound 'bigint' column types in the
first place. When this was rectified all hell broke loose.

The current situation per DBD::SQLite version

1.29 ~ 1.33:  everything works fine, for large values DBD::SQLite loses
              precision on perl binaries with ivsize == 4 (just like integer
              math within perl itself)

1.35:         Nothing works *regardless* of ivsize. Binding a >32 bit value
              as either SQL_INTEGER or as SQL_BIGINT is impossible (an
              exception is thrown from within DBD::SQLite). DBIC simply strips
              the bindtype altogether and issues an "UPGRADE!" warning.

1.37 ~ 1.40:  Everything works, except for the annoying fact that DBD::SQLite
              issues a spurious 'datatype mismatch' warning when one tries
              to bind a >32 bit value with ivsize == 4. RT#76395
              Warning is silenced for the time being within the guts of DBIC.

On the SQL_INTEGER => SQL_BIGINT change: according to
http://www.sqlite.org/datatype3.html#storageclasses all numeric types are
dynamically allocated up to 8 bytes per individual value. Thus it should be
safe and non-wasteful to bind everything as SQL_BIGINT and have SQLite deal
with storage/comparisons however it deems correct.

11 years agoFix and guard against erroneous use of list context in internal DBIC code
Peter Rabbitson [Sat, 5 Oct 2013 08:14:38 +0000]
Fix and guard against erroneous use of list context in internal DBIC code

This situation is dangerous in case the end-user employs something like
DBIx::Class::Helper::ResultSet::IgnoreWantarray

Besides the trivial fix in ::Row::copy, this commit introduces the
DBIC_ASSERT_NO_INTERNAL_WANTARRAY=1 mechanism (which will be
automatically picked up and engaged by our CI due to eed5492f). As a
bonus the check is usable on DBIC dependencies as well.
