A new command is added for commenting or uncommenting SQL code (depending
of the state of the first line of the block).
It is bound to "Ctrl+/" as used by many IDEs ("Ctrl+-" is more standard as
Zoom out). Unusual Scintilla binding for "Ctrl+/" is removed for avoiding
interference.
If there is no selection, the current line is un/commented.
See issue #1614
Each time the searched term or the dialog is closed, the find process in
the QScintilla widget is cancelled. This avoids the problem mentioned in
issue #1612 and similar others, like finding, then changing the searched
term and pressing Replace. In all these cases Replace only finds the next
term to be replaced without performing any actual replacement.
This commit fixes the SQL export which did not quote the field names in
the INSERT statements.
This also simplifies the code for escaping SQL identifiers.
In the Edit Table dialog we used to call our alterTable function (which
works around SQLite's missing full ALTER TABLE support by - besided
other things - copying all the data of the table) for pretty much every
change immediately. This was taking a lot of time for larger tables.
Our alterTable function allowed any number of changes if they affect
only one field of the table at once. So we could have reduced the number
of calls a lot by just using that capability. Instead however, this
commit improves the alterTable function to make possible transforming a
table completely in just one call. It does so by taking the new table
schema and using that without further modification. It also takes a new
parameter to keep track of what column in the old table becomes what
column in the new table, so the data can be preserved.
This commit obviously also changes the Edit Table dialog to make proper
use of the new features. This means that whatever changes you make to a
table, you will only have to wait once until for the alterTable call,
and that's when clicking the OK button.
See issue #1444.
waitForDbRelease receives a parameter for waiting, cancelling the other
operation or asking the user; defaulting to ask.
The wait option is used for the conditional formatting, so it doesn't
interfere with the loading. This avoid opening a dialog when scrolling
the table over a still not fetched area with conditional formats.
And it is done independently of the threading model supported by SQLite.
This adds support for the REGEXP operator using the syntax /regexp/ in the
filter line boxes.
A new helper option for a not-containing filter is added using this new
syntax. This could be simplified using a NOT LIKE filter, but we don't
currently support that.
The "Use in Filter Expression > Containing" option escapes a possible
slash in the beginning, so it is not interpreted as a regexp filter.
See issue #1522
This slightly changes the behaviour regarding the read-only mode in
project files. It makes sure that we always respect the user's choice to
open a file in read-only mode, even if the project file says it wasn't
opened in read-only mode before.
When opening a database in read-only mode and creating a project file,
save the read-only flag in the project file.
When loading a project file with a read only flag set, open the database
in read-only mode.
See issue #1598.
This adds a label to the status bar which becomes visible whenever the
database is busy. It also specifies the currently running action. Also
add a button which allows you to cancel this action at the next
opportunity.
Note that this doesn't work for the Execute SQL tab yet which requires
some more rewriting of the code there.
When a conditional format is used and the table does not load all the rows
at once, a deadlock ocurred when scrolling to a not yet loaded area.
This avoids the deadlock by unlocking before the conditional format query
is performed.
Additionally the cancel-query dialog is avoided when the threading mode of
SQLite is Serialize, since in that case the queries can be sent to SQLite
concurrently.
See discussion in PR #1503
If we execute a select statement and there is some trailing whitespace or
comments in the buffer, we are passing that to SQLite and fooling
ourselves thinking that it may be a query modifying the database. Since
we aren't very smart about knowing which queries modify the database, this
change at least avoids this particular case by breaking when there is only
trailing whitespace and comments.
The issue has probably origin in #1455, since previously we didn't pass
the comments to SQLite.
This commit changes the project file format (and some internal data
structures) to support multiple sort columns in the Browse Data tab.
Note that this does not add actual support for multiple sort columns,
it's just a preparation for that.
After setting a filter, the user can select from the context menu in the
filter line a new option "Use for Conditional Format", that assigns
automatically a colour to the background of cells fulfilling that
condition.
The formatting is preserved after the user has removed the filter. Several
conditional formats can be successively added to a column using different
filters.
The conditional formats of a column can be cleared when the filter is empty
selecting "Clear All Conditional Formats" from the filter line context
menu.
The conditional formats are saved and loaded in project files as other
browse table settings.
A new class Palette has been added for reusing the automatic colour
assignment of the Plot Dock. It takes into account the theme kind of the
application (dark, light) for the colour selection.
A new class CondFormat for using the conditional formatting settings from
several classes. The conversion of a filter string from our format to an
SQL condition has been moved here for reuse in filters and conditional
formatting.
Whether the conditional format applies is resolved by SQLite, so filters
and conditional formats give the same exact results.
Code for getting a pragma value has been reused for getting the condition
result, and consequently renamed to selectSingleCell.
Possible future improvement:
- New dialog for editing the conditional formatting (at least colour and
application order of conditions, but maybe too: adding new conditions and
editing the condition itself).
* Fixed code style
* Added last location saving and loading per action type
This saves and loads different paths per action type when presenting the
native file dialog popup.
Add a new dropdown box to the Import CSV dialog to set an ON CONFLICT
strategy when importing into an existing table. You can now choose
between the old and still default behaviour of aborting the import in
case of a conflict, ignoring the conflicting row from the CSV file, and
replacing the existing row in the table.
See issue #1585.
Make sure to show the correct error message when there is an error
during CSV import.
Make sure to release the DB handle used for the import before rolling
back to the last savepoint in case of an error in the CSV import. This
avoids a deadlock situation.
See issue #1590.
SQLite 3.25.0 introduced an extended ALTER TABLE command which now
allows renaming an existing field. Before this we were emulating this
functionality in our code. There are however three reasons to switch to
the new feature from SQLite, even though it doesn't safe us any code:
1) It is faster because it does less steps
2) It is less error prone for the same reason
3) It is better at also renaming the field in triggers and views
This is somewhat improving the situation in issue #1444 but not
addressing the main problem described there.
There are cases where the default configuration makes impossible to
use the application, due to some misbehaviour, like in issue #1560. This
new command line option allows users to set any setting to any value.
The setting is not saved unless user enters Preferences and saves the
current values. This allows overriding the preferences for the session
duration from the command line and also overriding the defaults for the
first session to work around problems with those defaults.
See issue #1588

Since Qt 5.10, the Windows Vista style has been moved to its own plugin. This plugin must be included in order to show the new style. It will be included for the 64-bit build only for now, since we are using a different Qt version (5.7) for the 32-bit build.
See #1580.
