A second Ctrl+Click over an already added column changes the direction of
any column.
Before this change, the effect was only applied to the last selected column
and a second Ctrl+Click on the other columns triggered a requery without
having changed anything.
This was mentioned in PR #1810. See also issue #1761.
Qt's isRightToLeft() returns true only for all left-to-right characters
in the string. That prevents the automatic switch to LTR Text mode, when
the text contains one or more left-to-right characters.
See #1793 and #1929
This restores the Qt text widget that was replaced by a QScintilla one in
45c1e2abfd
QScintilla does not support right-to-left scripts like Arabic, so QTextEdit
is still needed for these languages. Since the QScintilla editor has other
advantages already explained, it is preserved for general text edition.
RTL texts are detected when data is loaded and the Qt editor is
automatically selected. This is done both when loading data from the cell
and when interactively typing RTL characters in the Cell Editor.
All these changes can be undone if a new QScintilla editor supports RTL
texts.
See comments in issue #1793
Always send the fetched() signal when a RowLoader thread has finished a
fetch task. Before this the signal was only sent when some data was
actually retrieved from the task. This fixes some rare problems in the
Execute SQL tab where the query for determining the row count of a
SELECT statement changes something, so the subsequent row loading task
does not return any rows after all.
The only case I know of is when loading an extension using the
'SELECT load_extension()' function. The load_extension function is
actually called twice when SQLite for some reason reports that rows
where returned from this statement. These calls are:
SELECT COUNT(*) FROM (SELECT load_extension('...'));
SELECT load_extension('...');
After the first call is executed, the extension is loaded. So the second
call does not return any rows and we indefinitely wait for the rows we
expect. Strangely enough this only happens for some extensions.
The change here should have no side effects becaue the signal is only
connected to one slot which skips most steps when no rows where fetched.
See issue #1932.
Instead of registering the error log callback function every time a
database file is opened, we now register it only once when the
application is first started. This way we can avoid calling
sqlite_shutdown which can have unintended side effects.
See issue #1932.
While testing the original database from issue #1892 which contains
hundreds of tables and fields, I noticed how long the loading of the
database structure takes. This is especially problematic since it needs
to be reloaded on various occasions, e.g. running most statements in the
Execute SQL tab, which stalls the application every time.
According to a profiler it is the QIcon constructor which requires most
of the time. By introducing this small icon cache class we can reduce
the time for loading icons to almost nothing.
While still not perfect the UI already feels much more responsive with
this patch.
Matter came up WRT #1880. In reviewing, several other instances
were found where same file filter as a string literal was repreated.
This commit centralizes these file filters to one location. Filters
are declared `static const` to prevent accidental modification.
Also applied is a fix to #1881. QMessage at end of Import CSV is removed.
Saving cannot be done in the class destructor, since it seems that the
sizes have already change in that moment. Now they are saved under request
of the Main Window at the same time when the Main Window state is saved.
See issue #1889.
Whenever the splitters between the SQL editor, the table result and the
last execution results panes are moved, the sizes are saved to memory (for
performance) so the next SQL tab to be opened restores them. When an area
is destroyed the last saved settings are saved to disk, so they are ready
for the next execution without much impact in disk utilisation.

When opening a project file the following exception is raised in
src/sqlitedb.h:208

This is related to 64a596a887
Saving and restoring of quote and separator characters did not work as
expected in the Import CSV dialog since the last commits. A missing
"else" made us try to save the string "Other" as the quote character
when a custom quote character was selected. Also the translation from
and to the saved format on disk had its problems.
See issue #1860.
This adds a new dialog, accessible from the Remote tab in the Preferences
Dialog, which allows the user to configure the proxy to use for all
network connections.
The new default is to use the system-wide proxy settings.
See issue #979.
The dbhub.io server provides us the last modified date of the database
when cloning it. Because we send the last modified date back to the
server when trying to push a database, it makes sense to initially set
the last modified date of the local file to the date provided by the
server.
See issue https://github.com/sqlitebrowser/dbhub.io/issues/101.
This adds support for more characters as field separator and for quoting
in the CSV import. Before this we only supported ASCII characters, with
this we support all characters which when UTF-8 encoded require up to
16 bits.
See issue #1860.
Problem traced to QFile::exist() producing message when passed an empty QString.
Fix is to test QString length before any QFile::exist() usage with that string.
Compile with ALL_WARNINGS using GCC 8.2.1.
Encountered approximately dozen warnings with this pattern:
[path to sqlitebrowser root]/src/[somesourcefile]:line:cursor: warning: declaration
of ‘data’ shadows a member of ‘ClassName’ [-Wshadow]
OtherDataType data = ....line of code at line given above...

It appears there is a variable named 'data' within Qt global scope. Using 'data`
as a variable name, even one limited in scope to small lamda expressions, causes
compiler some grief.
Commit resolves the warnings in affected files. No problems apparent during execution.
Requires CSV stress-testing.
Include path used for QHexEdit in EditDialog.cpp is "implementation specific"
to how DB4S uses the QHexEdit library. Change is to make usage of library
more generic.
It turned out that on some platforms we still aim to support the stdlib
had not yet implemented std::regex. For this reason we want to avoid
using it for now.
In the particular use cases here it was also not the best solution. It
was faster to write using a regular expression instead of a hand coded
loop but clearly a simple loop should be more efficient here.
See issue #1873.
Respect the suggested order of the licences as provided by the dbhub.io
server instead of sorting them alphabetically by their internal key.
Also remove the hard-coded "Unspecified" licence option because the
dbhub.io server provided its own "No licence specified" option.
This adds a built-in, default certificate which enables read-only access
to dbhub.io. This should make it easier to try out the remote features.
When trying to open the Push Database dialog, a message with more
details and all required links is displayed.
We started to use Niels Lohmann's JSON library instead of the one
included in Qt for the Export JSON dialog a while ago because Qt's
implementation showed some problems. To avoid any similar issues and
because Niels' library has a much nicer API, this commit migrates all
our code to his library.
In the Browse Data tab updating a row after having updated its primary
key or part of it before was broken for multi-column primary keys. When
updating the value of a primary key column and then updating any part of
the row afterwards, we were still using the old value until the view was
refreshed. With this commit it is possible to immediately update the
row using the updated primary key values.
See issue #1834.
This improves the performance for loading row data with my setup by
about 10%. Incidentally, the conversion from Qt to STL containers
reduced the performance by about the same number.
This adds another primitive benchmark tool which in this case helps
measuring the time required to load all remaining rows from the selected
table. When activated using the LOAD_DATA_BENCHMARK define, it opens a
message box after loading of all rows using the fetch-all-data button in
the Plot Dock is clicked.

When a PRAGMA query did not return any value (most notably the PRAGMA
foreign_key_check after editing a table using the Edit Table dialog), we
used to print an error message to the console. There were no further
side effects but the message could be irritating. This extra error
message is removed by this commit.
