461ef575bc Always escape the table names when creating the SQL statement
Since some databases are case sensitive if part of the query is quoted,
then we should ensure that all instances of the table name are escaped
unless the test is delibrately testing the non-escaped case.

As a result, this commit also removes some expected failures pertaining
to PostgreSQL and also adds an entry to the list of tables being dropped
when a test is finished.

[ChangeLog][Sql][PostgreSQL] QSqlDatabase is now stricter about table
names when used with record() and primaryIndex(). If the tablename was
not quoted when it was created, then the table name passed to record()
and primaryIndex() needs to be in lower case so that PostgreSQL is
able to find it.

28702cb239 Initialize the QSqlQuery to be invalid when creating a sql model
When QSqlQueryModel or QSqlTableModel is created it will create a
QSqlQuery which defaults to using the default QSqlDatabase connection.

If this connection belongs to another thread then it will throw a
warning as this is not safe to use. Since the QSqlQuery is always
recreated when a query is set, the instance which is a member of
the class can effectively be invalid until a new one is set.

8635ad1b59 psql: Add expected failures where the table name is case sensitive
Currently there is a bug in Qt regarding the PostgreSQL driver as it
does not correctly escape the table names when constructing queries
internally. Therefore, these tests are marked as expected failures until
the bug itself is fixed in Qt.

submit() does. The reason in Qt 4 for excluding OnFieldChange
was that there was no opportunity to revert. The model was
refreshed, causing all changes to be lost. In Qt 5 a failed

to revert.

c3ae1c76f3 QSqlTableModel: support refreshing inserted rows with auto columns
Previously, selectRow() did not work after INSERTing a new row into a
table with an automatically populated column. It did not work because
the model did not know the primary values for the new row. Newly
inserted rows were therefore not refreshed in OnFieldChange and
OnRowChange edit strategies.

This change provides support for the typical simple case where a single
column is populated by the database and can be retrieved with
QSqlQuery::lastInsertId().

Commit 10ff9de91b introduced the
optimization of ignoring non-changes, but it overshot the mark.
It neglected to consider that QVariant's equality operator does not
compare the null flag. It also failed to consider that setData() has
a useful side effect of setting the generated flag in a column of a
pending INSERT. This is important when the application actually wants
a NULL to be inserted into the column.

10ff9de91b QSqlTableModel: don't cache unchanged value in setData()
This is good for performance in terms of avoiding unnecessary
database activity and keeping the cache smaller.

Detail:
This change was not included in the big refactoring of QSqlTM. The
idea was that the model shouldn't second guess the intention of the
application and maybe the application wants to cause a submit.
It was a marginal consideration.

Now I think it's clear that our interest in not unnecessarily
expanding the cache outweighs that. In addition, applications can now
call selectRow() if they worry that the database values for the row
have changed and want to set a value back again.

Test added.

5fe272f68a QSqlTableModel: fix segfault when overriding selectRow()
The STL-style iteration over the cache in submitAll() assumed the
iterator would remain valid until reaching cache.end(). This failed
to consider that virtual selectRow() might be overridden so that
it removes rows from the cache. For example, it might call select()
which would empty the cache.

The new approach checks at each iteration whether the row is
still in the cache. Using foreach here is justified by its fitness
for purpose and readability.

New test included.

7389c09637 QSqlTableModel::selectRow(): fix failure on uncached rows
This method was originally intended for refreshing rows after
submitting changes. It should also work for refreshing rows
that are unchanged (i.e., not cached), but did not because
constructing the primary values depended on the cache. As a
consequence, the WHERE clause for the query was not created.

Fixed by deriving primary values for uncached rows from the
query record. Note that the cache is still authoritative for rows
it holds. This is important because the prmary values there may
differ from the original query record due to changes to columns
of the primary key.

Includes new test.

83c9ebbd66 QSqlQueryModel::setQuery() don't use deprecated reset()
Previously the method attempted to reset only as a last resort.

Now reset() is deprecated and resetting must happen between emitting
modelAboutToBeReset() and modelReset(). Since this suffices in all
cases to notify views that they must reinterrogate the model, it is no
longer necessary to signal explicitly row removals and insertions
within the scope of the reset.

Additionally, fetchMore() is now called within the scope of the reset
so insert signals do not have to be emitted here either.

This improved handling of resetting in QSqlQueryModel also allows the
cache in QSqlTableModel to be cleared directly at select().

This change may actually allow views to operate more efficiently since
they no longer have to react to separate row removal and insert
signals. Views can avoid pointless deallocation and reallocation
by considering row count only after the reset is finished. The cost is
that the columns and horizontal headers must be considered in the view
at each setQuery() call. In any case, it is not clear that trying to
be smart about this in the model justifies additional complexity.

Tests had to be adjusted where they expected explicit row removal
and insert signals.

26450fe6a6 QSqlTableModel::removeRows() enforce edit strategy
For OnFieldChange and OnRowChange, we don't want more than one row in
the cache with uncommitted changes. This could happen if deletion in
the database fails while other changes are pending.

Chosen solution is to return false if other rows have pending changes.
Also, we only allow 1 row removed at a time.

Updated test, changes and documentation.

108748404b QSqlTableModel::setData(): no longer autosubmit for OnRowChange
The model can never do a good job of knowing when user moves to a
new row in the view. Faking it by detecting when another row
is changed was not a good solution because it cannot detect
when the last edited row is left.

Either the view should automatically submit when the user leaves
a row or the application should provide a way to submit.

This change made it possible to reuse the logic of flags() in
setData().

f6ca63f896 QSqlTableModel::setData()/setRecord(): fix incorrect row
For OnFieldChange and OnRowChange, before submitting new changes,
setData() and setRecord() attempt to submit pending changes and
revert them upon failure. However, they fail to consider that
reverting pending insertions removes rows from the model. As a
result, the new change can be applied to a row higher than intended.

One possible solution would be to adjust the targetted index for the
removed rows, so that the intended row is affected by the new change.
But this still causes the strange editing experience as rows jump
up just as they are being edited.

It does not seem right in the first place for the model to initiate
reverting changes. It should be up to the application to decide what
to do when data cannot be committed. In particular, setData() and
setRecord() should not have the side effect of reverting already
pending changes.

The chosen solution is simply to refuse new changes that don't make
sense for the edit strategy. For OnFieldChange, flag() will
indicate read-only when editing is blocked by a pending change.

Since setData() and setRecord() submit data immediately for
OnFieldChange, it no longer makes sense to resubmit changes
automatically before a new change.

For OnRowChange, setData() keeps the behavior of automatically
submitting a pending row before starting on a new row. This is
historical behavior and is probably motivated by the fact that
QTableView does not automatically call submit() when editing leaves a
row. The obvious shortcoming of this is that the last row to be edited
will not be submitted automatically. It also prevents us from flagging
rows other than the pending row as read-only.

For OnRowChange, setRecord(), being row-oriented by nature, should
submit the change immediately rather than waiting for the next call
to setRecord(). This makes setRecord() consistent with insertRecord().

888fed8065 QSqlTableModel: use selectRow() for field and row edit strategies
Calling select refreshes the query data but disrupts view
navigation.

For OnFieldChange and OnRecordChange it makes sense to only
select the row in question. This does not disturb view navigation.

Assume disruption of view navigation is not a problem
for OnManualSubmit because the user or application decides
when submitAll is called.

b979956ec4 QSqlTableModel: handle changes between submit and select
Once an insert has been submitted, the cached record behaves like an
update. For row bookkeeping, we still have to remember that it was
originally inserted and is not in the query rows.

Between submitting a delete and selecting, we remove the values
from the deleted record. This causes a blank row to be displayed.
Read-only flag is set for cells in deleted row.

Reverting between submit and select means going back to the last
submitted values.

When removing rows, it's better to process from highest row numbers
to lowest. This avoids complications with higher rows shifting down
when lower rows are removed.

555aa4439b QSqlTableModel::commitAll(): replace row removal hack
The purpose of the hack was to fool QSqlQueryModel into signaling the
removal of extra rows via rowsRemoved(). The extra rows are the
inserted rows generated by QSqlTableModel.

While it is important to signal the removal of all the rows before
requerying after committing changes, there is a cleaner way. The
table model should remove its rows before the query model removes its
rows.

Iterating backwards avoids having to decrement row numbers above ones
being removed.

Expected test results have been adjusted for these changes.

7b726900ec QSqlTableModel::setRecord(): emit dataChanged() consistently
Previously, if any fields in the supplied record could not be matched
with a column in the target table, dataChanged() was supressed for all
columns for OnManualSubmit. This is not good because it prevents other
views from noticing the fields that *do* change.

It's simplest and probably more efficient just to emit
dataChanged() once for the whole row. Fewer signals need to be
processed and in typical cases much or all of the row is likely to
be changed anyway.

5953304bc5 QSqlTableModel::setRecord(): do not try to detect value changes
In an apparent attempt to be economical with emitting dataChanged()
and submitting SQL to the databse, setRecord() compares each field
value of the record with the old value, taking action only when
a difference is detected.  Several complaints against this code are:

-The comparision does not work on float type.

-It is really up to the application and database to decide this. The
model should make few assumptions. The application has the option to
omit fields from the record that should be ignored.

-The current behavior seems to assume that the "old" values are the
current state of the database, but the database may have changed since
the model was last refreshed.

-The code compares the value from record(), which probably
corresponds to the EditRole, with the DisplayRole value from data().
