Instead of reporting an error and declining to load the file (XML)
or failing to enter a value (SQL) when a bad date is found in the
database, use a 0 time stamp (1970-01-01 00:00:00 UTC). Adds a warning
in SQL backends; there was one already in XML.
We don't use floats in GnuCash, we use doubles (and those as little as
possible), but dbd-sqlite3 is broken in that it stores only floats.
Simply casting floats to doubles introduces bogus additional digits
that can cause round-trip tests to fail. Instead convert floats to
doubles by multiplying by 10E6, rounding, then dividing by 10E6.
properly - corrupted business data
Turned out to be a pointer/value mismatch between <CT_NUMERIC>load()
and most of the setter functions, so the address was getting set
as the value.
Four date elements were affected: GncEntry::date, GncEntry::date_entered,
GncInvoice::opened, and GncInvoice::posted. The problem arose during the
cleansing of Timespec from the reports; the setter functions for those
elements were converted to time64 but no provision was made to the SQL
backend to pass them time64 instead of Timespec*.
This commit adds a new column type, CT_TIME64, and changes the column
types for those elements to CT_TIME64.
Only string values should be quoted in queries; in particular NULL
isn't a string value and must not be quoted.
Note that this is a less than perfect solution because it doesn't use
the Database's quoting function and so doesn't escape quotes, linefeeds,
or carriage returns inside the string. That's because the SQL generating
logic is independent of the connection class and can't easily get to it.
Instead of using the more generic string constructor. The struct tm
constructor is several times faster and this change speeds up
transaction loading by 2x.
It is split into
- /libgnucash (for the non-gui bits)
- /gnucash (for the gui)
- /common (misc source files used by both)
- /bindings (currently only holds python bindings)
This is the first step in restructuring the code. It will need much
more fine tuning later on.
