TODO:

"Although SQLite parses named transactions, the names are ignored.
|
|
SQLite does not support nested transactions. If you split the SQL statements in a transaction
|
|
over several sqlite_exec() calls, you must be prepared to handle failure in each of these calls.
|
|
If a failure occurs SQLite will return a non-zero value. After that, SQLite will revert to the
|
|
default behavior of giving each SQL statement its own transaction until a new transaction is started."

TODO: table merge automaton:
|
|
Imagine you have a simple database with two tables, and a third to join them as a
|
|
many-to-many relationship. Someone sends me an SQLite database as a file which has the
|
|
same structure, but the data is different. I want to merge these two databases
|
|
together keeping all of the relationships intact, without duplicating data.
|
|
|
|
For example, if the tables were "customers" and "products" and the one in between
|
|
"orders", there is the possibility that some customers and/or products might be the
|
|
same, but with different primary keys. The problem is that since the databases were
|
|
independently created, a simple union will break the relationships since the primary
|
|
keys will overlap.
|
|
|
|
I can think of brute force ways to do this, but I was wondering if anyone might have a
|
|
good algorithm or technique to accomplish this efficiently.

- ODBC driver (hello mattr!)
|
|
- Access -> Kexi migration tool (done)
|
|
- scripting
|
|
|
|
=== Kexi Parts TODO ===
|
|
- kexipart.h: add KexiPart::AboutData : public TDEAboutData
|
|
and
|
|
#define KEXIPART_EXPORT_COMPONENT_FACTORY( libname, partClass, aboutData ) \
|
|
K_EXPORT_COMPONENT_FACTORY( libname, KGenericFactory<partClass>(aboutData) )
|
|
- add gui for viewing full part information
|
|
|
|
=== General TODO ===
|
|
- avoid using veryvery long names for objects
|
|
- IDEA: Learning module. A special optional pane which shows what commands are sent to server
|
|
for learning purposes.
|
|
- IDEA: Server-side wrapper for db connections (very simple) that allows anonymous [1]
|
|
(or any predefined group of users [2])
|
|
-- wrapper handles connections by validating *virtual* usernames and passwords for [1] case,
|
|
or providing unique virtual user names and passwords for [2] case
|
|
-- on the server side, wrapper connects to database server (it can be available locally or remotely)
|
|
using it's private user name and password. Thus, we only need one *physical* user name and password
|
|
for multiple users. Virtual names/passwords are mapped to physical one.
|
|
This is a solution for hosted database servers where it's hard to create as many users
|
|
as actually needed.
|
|
-- Priviledges are mapped as well, and translated. By default, user A could be able to create his/her
|
|
own database and drop it. He/she couldn't be able to do the same with user's B databases,
|
|
until user B allow this. The same for creating tables, and writing data.
|
|
-- wrapper secures server from too large data sets being sent to server
|
|
(parameters need to be configurable)
|
|
-- it's all dedicated for Kexi; so it's NOT a generic wrapper for any database client.
|
|
- add "ADVANCED" find dialog: like in Mozilla Advanced Address Book Search window
|
|
|
|
=== USABILITY TODO ===
|
|
-add "Simple/Advanced Usage" global option
|
|
--for simple usage:
|
|
--use captions everywhere possible, instead of names (tables, fiels, etc.); names should be autogenerated
|
|
|
|
=== i18n ===
|
|
- plugins/forms/kexiformpart.cpp "Best Fit" instead of "To Fit" (pl=Najlepsze dopasowanie)
|
|
- KexiQueryDesignerGuiEditor::initTableColumns(): i18n("Visible") --> i18n("Column visible", "Visible")
|
|
- add comment for translators: i18n("'empty' is an adjective here", "Empty database")
|
|
-"Could rename table \"%1\" using the same name."
|
|
--> "Could NOT rename table \"%1\" using the same name."
|
|
|
|
I am using update_kexi_po to recreate kexi.po file. THis will run cd koffice/ && make -f admin/Makefile.common package-messages
|
|
|
|
|
|
=== Import/Export Framework TODO ===
|
|
-KEXIDB: add lower level functions like: "getting table names list", "getting table schema",
|
|
"getting index schema"
|
|
|
|
=== Combo box editor TODO ====
|
|
-new layout: a lineedit + dropdown button + popup tableview, when needed
|
|
-use (and add few) methods for tableview to enable adjusting it for use it as dropdown tv
|
|
--add scrolling for mouse dragging
|
|
-dropdown tv has to contain:
|
|
--QSizeGrip at the bottom corner
|
|
-in kexidb: implement combobox settings for the foreign field:
|
|
--ordered set of fields that are visible in popup tableview (ie. just query that is bound with the column)
|
|
-use multi-key relations from kexidb
|
|
- copy should handle "displayed" value, not the real one
|
|
(maybe let's use a custom clipboard mimetype? (containing a bound value) -- otherwise
|
|
it will be not posible to paste the copied value)
|
|
- fix support for query as the row source
|
|
- (forms combo) repaint (remove focus rectangle) when other widget is focused using a mouse click
|
|
|
|
=== Table View TODO ====
|
|
- do not accept when enterind "-" for unsigned numeric types
|
|
- add a functions for moving/cutting/copying/pasting rows
|
|
- extended support for enums (combo boxes)
|
|
- add top-left button that allow select all rows
|
|
- enable clicked vheader button to select given row
|
|
- enable column dragging
|
|
- add action "restore original column order"
|
|
- add possibility of renaming column by 1) dbl-clicking header 2) "rename column" action
|
|
- more actions (as in Format and Insert menus of MSA2k3)
|
|
- add own impl. (based on Qt) for date/time editor because:
|
|
-- no focusSection(), etc. is available in current impl.
|
|
-- frames cannot be easily removed
|
|
-store last sorting column (and type) and load it on KexiTableView::setData()
|
|
(not it's only cleared)
|
|
- replace KexiDB::RowData usage in KexiTableItem with something faster
|
|
- TODO RELATED TO CELL EDITORS:
|
|
- signal on situation when user e.g. pressed alpha key when only numeric chars is allowed
|
|
- signal when null/empty value forcell isn't permitted
|
|
- signal when repeated value isn't permitted
|
|
- add support for cut, copy & paste of cell's contents (get shortcuts from TDEStdAccel)
|
|
HINT: removing Qt::WStaticContents from KexiTableView ctor fixed repaint problem
|
|
the problem was with repainting when hscrollbar disapperars....
|
|
- KexiTableView loads all data from the table: very slow and consumes a lot of memory:
|
|
(e.g. for each record with 3 fields: 1 integer, 1 text and 1 float consumed ~350B)
|
|
- ctors and dtors are WAY TOO SLOW!
|
|
- add an option: for bigger tables load only part of the table data
|
|
- optimize MySQL record size
|
|
- add focus rectangles for cells:
|
|
http://mfc.dundas.com/mfc/grid/index.aspx?section=Grid&body=focusrectangles.htm
|
|
- add more cell types & options:
|
|
http://mfc.dundas.com/mfc/grid/index.aspx?section=Grid&body=celltypes.htm
|
|
--including: red corner with a note; sliders; radio buttons
|
|
- highlight sorted column's cells slightly darker, like in current TDEListView's impl.
|
|
- clicking on a header section (to sort), it ensures current cell is visible, but
|
|
only y-position should be changed, not x
|
|
- add support for crossed out rows - that can be used for results of DELETE queries
|
|
(see http://www.gnome-db.org/images/screenshots/mergeant_table_data.png)
|
|
- add combo boxes for fields filtering in column headers,
|
|
as in http://www.sqlmanager.net/i/scr/mysql/manager/Main%20100.gif
|
|
- display autonumber indicator in autonumbered column(s)
|
|
- reimplement header widget to better show sorting indicators
|
|
- display tooltip over cells that are to small to display entire contents
|
|
- Add icons for conditional formatting: http://blogs.msdn.com/excel/archive/2006/05/09/594200.aspx
|
|
(displaying icons is already possible using custom properties, BTW)
|
|
- display [null] values in boolean fields, e.g. as [?]
|
|
- allow to select entire rows, columns and grids as in a spreadsheet;
|
|
offer copy/cut/paste/copy-to-file/clear for such selections
|
|
- tooltips:
|
|
-- implement tooltip manager (this will allow to create custom tooltips)
|
|
-- use if ( QApplication::isEffectEnabled( UI_AnimateTooltip ) == FALSE ||....
|
|
as in qtooltip.cpp:564
|
|
-- implement custom tooltip for large texts and BLOB, add "zoom" option at the bottom of the tooltip
|
|
(zooming should not show a modal dialog but rather a widget inside the TV)
|
|
-- add the same zoom option to the context menu
|
|
-- also show tooltips when the content is only partially visible
|
|
- fix horizontal scrollbar's width updating: large tables like 'tabkodypocztowe1' hide the 'last' and 'new' buttons
|
|
- display default values for BLOB types
|
|
|
|
- add "None" option for editors supporting 3rdState, e.g. int, string (needed for "default"
|
|
property of the Table Designer)
|
|
- fix repainting cells when moving down/up arrow at the window boundaries
|
|
(weird, win32 is not affected)
|
|
|
|
- (e.g. in table designer): in an empty row 1. drop down a type combo. 2. do not select enything an click outside
|
|
of it. 3.
|
|
- do not autoscroll vertically the contents if the current column is wider than the view
|
|
(my example: 'microsoft_terminology' table's 1st column) because the text us unreadable
|
|
valid even when we use arow keys only
|
|
|
|
- KexiComboBoxTableEdit::createInternalEditor():
|
|
set d->internalEditor visible and use it to enable data entering by hand
|
|
(for now only types based that use KexiInputTableEdit (Text, Integer..) allows data entry using keyboard
|
|
|
|
- display error message on top of table view if data fetching failed
|
|
|
|
==== ALTER TABLE TODO: =============
|
|
-add a function for editing indices (including multi-field indices)
|
|
2 methods: 1) in additional dock 2) in property editor
|
|
-add all missing properties (even when most are not working)
|
|
-add "index" information icon @ the left hand of line with key(s) that is/are indexed
|
|
-in propeditor: auto-sync pkey, unique, required & indexed properties on changing;
|
|
add message boxes if needed
|
|
-for 'column width' property: add 'default' value at the beginning
|
|
-propose index key (ask for name) on saving tables without index (allow to bypass this message)
|
|
- re-add "tablepart_toggle_pkey" action after shared toggle actions fix:
|
|
--when propeditor is focused, there's a problem with syncing on/off state of toolbar button
|
|
of "tablepart_toggle_pkey" action
|
|
--> altertable view doesn't receive the signal about toggling (because it's not focused)
|
|
|
|
==== Forms TODO ====
|
|
-add "datasheet view" to db-aware forms
|
|
-add [NewFormDefaults] option group and:
|
|
--add "autoTabStop" (bool)
|
|
^^^ implement above so Form::autoAssignTabStops() will be called before form saving
|
|
and before switching to data mode (this is already performed in FormIO::saveFormToDom().
|
|
- add setting expressions for data-aware widget's dataSource
|
|
- add setting anonymous (not stored) queries as form's dataSource
|
|
- display "Autonumber" string for data-aware widgets
|
|
- implement shared action categories to filter out them in 'assigning actions to push buttons'
|
|
- implement "restore default properties" action for widgets
|
|
- allow form's surface resizing when there's global layout defined
|
|
- fix repainting form's surface boundaries repainting when its size is changed by entering
|
|
value in the propeditor
|
|
- fix spring behaviour: it cannot be shrinked if its inside a layout
|
|
- KTextEdit doesn't allow to set custom cursor (also in Qt Designer)
|
|
- support for multiple widgets selection in the property editor (requires changes to kexiproperty)
|
|
- handle older and newer formats in FormIO::loadFormFromDom()
|
|
- TDEAcceleratorManager::setNoAccel(QWidget*) - use it in data mode,
|
|
define "auto accels" form's property and if it's false
|
|
- find a way to create more meaningfull default names for widgets than button1, button2.
|
|
Maybe convert widget text (if available) using string2Identifier()?
|
|
Maybe ask user to enter meaningfull name (+"do not ask this question again" checkbox)?
|
|
See also http://charlespetzold.com/etc/DoesVisualStudioRotTheMind.html
|
|
- For newer widget types, add information for compatible widgets that
|
|
can be used instead of them. For best flexibility save this information in a form XML.
|
|
Example use: We have Kexi version N and N+1. In N+1 there's KexiFrame widget introduced that
|
|
extends QFrame with more features. Kexi N has no KexiFrame implemented but only QFrame.
|
|
When KexiFrame witget type has been encountered in the form's XML string,
|
|
Kexi N it is able to insert QFrame instead of KexiFrame (unsupported properties will be just ignored).
|
|
The result of substitution may be not accurate, so thing twice before adding such information
|
|
for a given widget type.
|
|
- add "buttonStyle" property for pushbutton widget with following values:
|
|
-- Button - the deafult
|
|
-- Hiperlink - clickable hiperlink will be displayed instead of button itself
|
|
-- Image - an clickable image will be displayed instead of button itself
|
|
For this value, aditional properties will make sense:
|
|
--- image, mouseOverImage, mouseDownImage
|
|
-- Thus, we'll have more consistent solution than MSA, which allows to
|
|
mess the form by setting hiperlinks directly also in Image box and Label widgets
|
|
- add "icon" property for pushbutton
|
|
- For "OnCLick" property:
|
|
-- allow to set hiperlink (and anchor) as value (i.e. so called "target location")
|
|
(see MSA's hiperlinkaddress, hiperlinksubaddress properties)
|
|
- frame widget:
|
|
-- add such fancy frame: http://www.themaninblue.com/writing/perspective/2004/08/05/
|
|
- tab widget: add color property for setting particular tab
|
|
- add a Scratchpad as in QtDesigner4, allows to drag&drop widgets between forms...
|
|
- Use RESET clause for TQ_PROPERTY, eg. RESET unsetPalette for paletteBackgroundColor.
|
|
Then, use bool QMetaProperty::reset ( QObject * o ) const to reset property value in the propeditor.
|
|
- Autoforms: allow to define groups of fields so the fileds can be displayed with nice groupo boxes.
|
|
(e.g. http://www.glom.org/screenshots/glom_data_details.png)
|
|
This definition shgould be made during table design, so we can reuse groupping information also in
|
|
autoreports and auto web forms. Especially usable for tables with lots of fields.
|
|
We could even define the groupping levels so top-level groups can be splitted using Tab Wigget.
|
|
- fix support for blob visible values for the combo box widget
|
|
|
|
==== Property Editor TODO: =========
|
|
- text does not fit well inside combobox editor
|
|
- double editor should be klineedit with doublevalidator, not spinbox
|
|
- add a hint for propertybuffer to allow properties to be displayed side-by-side
|
|
e.g. width, height properties ca be displayed this way. See also property editor
|
|
at http://freshmeat.net/screenshots/41728/

-KexiProperty: make it really shared (using QShared?)
|
|
-for each row (property) allow to define double-click-action dependent on property type,
|
|
* e.g. bool editor: toggle true/false,
|
|
* enum editor: select next value (circularly),
|
|
* fire selection dialog for filename editor, color editor, pixmap editor, etc.
|
|
* expand children for cells of type like "Rect"
|
|
* other types- by default: just move cursor to editor
|
|
- add support for "set" types (e.g. AlignTop|AlignBottom) and port form's objpropertybuffer to this
|
|
- add "description" label on the bottom of the property editor;
|
|
it should reuse Property::description() text
|
|
- support Variant type (needs update in Editor) so Property::setValue() won't show a "INCOMPATIBLE TYPES!" warning
|
|
(needed e.g. by KexiTableDesignerView for "defaultValue" property)
|
|
|
|
==== Query Designer TODO: ======
|
|
- add tables dropping from the browser
|
|
- add a dialog for inserting multiple tables at a time
|
|
- fix connections drawing
|
|
- make "1" and "inf" signs a bit larger (scalable)
|
|
- 'totals' are unused yet
|
|
- update query after change in Connection cache
|
|
- for queries like 'select * from a, b, c' allow to enter * in 'table' column
|
|
--this should also work when we're recreating field rows on switching from SQL view to design view
|
|
- query part: react on KexiProject::aboutItemDelete() and KexiProject::aboutItemRename() signals
|
|
- query parameters:
|
|
-- use a special dialog with validators compatible with the field type for getting query parameters
|
|
(currently KInputDialog is used)
|
|
-- use dialog like KInputDialog::getItemList() for supporting multiple values as query parameters
|
|
- support add "PARAMETERS [prompt1] datatype1, [prompt2] datatype2;" syntax to the parser,
|
|
and add query "Query parameters" dialog/pane, allowing to order parameters that user should
|
|
provide (Ks. eksp., p. 73)
|
|
- ADDINs: a tree dialog showing query dependencies, and query templates like these http://www.4tops.com/query_tree.htm
|
|
|
|
==== SQL Editor TODO: =====
|
|
- intergrate editor's (KPart) actions with KexiMainWindow's Actions
|
|
- win32: katepart on win32: void KateSyntaxDocument::setupModeList (bool force)
|
|
Works slowly for the 1st time because there is no cache.
|
|
Workaround: removed most of apps/katepart/syntax/*.xml files
|
|
- win32: fix freeze on 1st char entering
|
|
- win32: fix mmap for win9x (InterlockedCompareExchange() replacement is needed
|
|
-> see tdelibs/win/mmap.c)
|
|
- call tqApp->processEvents() on highlighting schema loading,
|
|
so 'wait' cursor can be visible on 1st loading.
|
|
- allow saving invalid queries (KexiQueryDesignerSQLView::storeNewData())
|
|
(for invelid queries, after opening SQL view should be shown automatically)
|
|
- allow to copy error message (e.g. using a copy button)
|
|
+ allow to select message text (use active label?)
|
|
|
|
==== Main window TODO ====
|
|
- propeditor dock window is hidden when a window in data view mode is active
|
|
(or no window is present). This feature is partially disabled
|
|
(using PROPEDITOR_VISIBILITY_CHANGES), though,
|
|
--REENABLE when blinking and dock width changes will be removed in KMDI
|
|
- add sorting projects information using KexiProjectData::lastOpened
|
|
- also add this info as "Database>Open Recent" menu subentry
|
|
- display errors when plugin library could not be instantiated due to a broken lib
|
|
- Project Navigator: display multiline item names is needed
|
|
- display progress bar (in the statusbar?) to indicate there're pending jobs
|
|
- enlarge the default main window size, currently it's ~50% ofthe desktop size
|
|
- not convenient as user is forced to enlarge the window by hand (settings are stored though)
|
|
- add "File->Save All" action
|
|
- add settings dialog, TDEConfigXT based simple version
|
|
+ about:config-like using tdeconfigeditor http://extragear.kde.org/apps/tdeconfigeditor/
|
|
(possible reuse of koproperty)
|
|
|
|
TODO: add SharedAction::setVisible() and use QMenuData::setItemVisible() where needed
|
|
|
|
CCPASTEUR:
|
|
-perhaps we'd reuse KDE Menu editor GUI?
|
|
|
|
=== KexiDB TODO ===
|
|
- add to field's properties list: input mask, validation rule, column width
|
|
- improve Expression class, add code for generating expression
|
|
strings in Connection::queryStatement()
|
|
- add dynamic resize for dict members like Connection::m_tables
|
|
- make KexiDB really ASYNC, multithreaded!
|
|
- implement relationships (foreign key information) between tables + storage
|
|
-- Support tree standard types of integrity rules as described at http://allenbrowne.com/ser-64.html
|
|
plus: Cascade to Null Relations
|
|
- implement GROUP BY clause + storage
|
|
- add schema to kexi__* tables on createTable()
|
|
- add support for creation temporary databases
|
|
- look at Connection::isReadOnly() to see if we can perform certain operations
|
|
requiring write access (create db, update db props, etc.)
|
|
- reuse ConnectionData::useLocalSocketFile for connections using socket file
|
|
- Connection::alterTableName():
|
|
--alter table name for server DB backends!
|
|
--what about objects (queries/forms) that use old name?
|
|
- PGSQL: use setval(sequence) to allow setting autonumber values by hand
|
|
http://www.postgresql.org/docs/7.4/interactive/functions-sequence.html
|
|
- optionally, introduce EDITABLE_AUTONUMBER_FIELDS driver flag
|
|
PiggZ_ js: and to ensure you always have id 1 and 2, well.....they would be anyway at db creation time as sequence = 0
|
|
js PiggZ_: but users ofter want to enter it anyway
|
|
js eg. sqlite increments its autonumber to 1001 if you enter 1000
|
|
js we want nothing more that that
|
|
js s/than that
|
|
PiggZ_ personally, i never want to enter a value into autonumber.....autonumber usually = pkey, so its best to let the db handle it
|
|
js If use want strict sequences to be used, he can:
|
|
js 1) hide autonumber column at all
|
|
js 2) set it not-editable
|
|
js 3) or just do not touch this column
|
|
PiggZ_ well then, its probably best to set the value of the sequence if a value is manually entered...if possible
|
|
|
|
- add an QAsciiDict of (reserved) SQL keywords and use it in Driver::escapeIdentifier()
|
|
- add FieldType and move things like typeGroupString() there
|
|
- CRASH: removing tables when a query still uses it.
|
|
HOW TO FIX: Add TableSchema::Ptr, QuerySchema::Ptr, etc.
|
|
-- related to above: add a possibility to return all objects (and optionally all opened objects)
|
|
thad depend on a given table
|
|
-- we could also add a GUI tree to show these dependencies
|
|
- add permissions information to connection : and - for sqlite - check if file is RO
|
|
and then set RO flag
|
|
- add kexi__toremove table, and use it to remove objects on begin connection
|
|
- [Kexi 0.2?] sometimes a user has got only one database availaliable on a server
|
|
(eg. when server is commercially hosted). Somethime user isn't just able
|
|
to create database because of insuffficient privileges.
|
|
Solutions --> add a possibility of sharing multiple projects within the same database
|
|
* kexi__* tables will be shared
|
|
* prefixes can be needed for table names (add option to set or unset this)
|
|
* prefixes will be hidden (stripped out) by KexiDB from real names, eg. 'mydb_mytable' -> 'mytable'
|
|
* let's set default prefix equal to database name
|
|
* within a group of "projects sharing the same databse" it will be easier to:
|
|
** mount (attach) external projects to an opened Kexi project
|
|
** run queries using tables from many projects
|
|
* disadvantages:
|
|
** decreased modularity and data encapsulation
|
|
** possible problems with transactions and user access rights
|
|
** custom table names can look weird outside Kexi
|
|
** the feature adds another level of complexity to KexiDB
|
|
-define "login timeout" setting (in seconds) so connecting can rely on this value.
|
|
The setting could be assigned to a given connection data,
|
|
but could be also defined globally for the application.
|
|
(note: db:login-timeout is defined by opendocument spec.)
|
|
- take a look at agrep: http://www.tgries.de/agrep/ -- looks loke it manages to convert
|
|
non latin1 characters to latin1, eg. '' to 'a':
|
|
"* option -ia searches case-insensitive
|
|
ISO characters are mapped to the nearest lower ASCII equivalent."
|
|
- support for COMPOUND KEYS, ie. keys with 2+ fields; http://en.wikipedia.org/wiki/Compound_key
|
|
- OPTIMIZATION: use PREPARE and EXECUTE statements for some backends, eg. for pgsql:
|
|
(excerpt from http://www.postgresql.org/docs/8.0/interactive/sql-prepare.html)
|
|
1. Create a prepared query for an INSERT statement, and then execute it:
|
|
PREPARE fooplan (int, text, bool, numeric) AS
|
|
INSERT INTO foo VALUES($1, $2, $3, $4);
|
|
EXECUTE fooplan(1, 'Hunter Valley', 't', 200.00);
|
|
2. Create a prepared query for a SELECT statement, and then execute it:
|
|
PREPARE usrrptplan (int, date) AS
|
|
SELECT * FROM users u, logs l WHERE u.usrid=$1 AND u.usrid=l.usrid
|
|
AND l.date = $2;
|
|
EXECUTE usrrptplan(1, current_date);
|
|
3. For completnedd, provide KexiDB API for "DEALLOCATE" as well
|
|
- Implement "copy table" feature.
|
|
To copy table t1 as t2 with data use: "create table t2 as select * from t1"
|
|
To copy table t1 as t2 without data use: "create table t2 as select * from t1 limit 0"
|
|
NOTE: pkeys, triggers, default values are not copied?
|
|
|
|
- BLOBs in MySQL: max_allowed_packet is 1MiB; read http://dev.mysql.com/doc/mysql/en/blob.html
|
|
and http://dev.mysql.com/doc/mysql/en/server-parameters.html
|
|
-- http://bugs.mysql.com/bug.php?id=1605 "MySQL protocol (it does not send 'chunked streams'
|
|
for blobs...The client has to read the _entire_ blob into memory."; use:
|
|
"select substring(document, 1, 10240) from documents where docid='3'" this to get chunks:
|
|
"select substring(document, 10241, 10240) from documents where docid='3'"
|
|
....
|
|
-- Other approach: store binary data using two tables 1st for metainfo about the data,
|
|
2nd for data chunks (e.g. 64KiB each): http://php.dreamwerx.net/forums/viewtopic.php?t=6
|
|
|
|
????? is it possible to just use a database and store the kexi stuff in a .kexi file?
|
|
jstaniek ruurd: you just dont want to create kexi__* tables on your database?
|
|
ruurd yes, and use an existing database.
|
|
jstaniek ruurd: that's planned but note:
|
|
jstaniek this option doesn't offer you atomic changes to database schema, by definition, because two database conenctions are started concurrently.
|
|
jstaniek So we'll need to behave with care...
|
|
jstaniek ruurd: of course this is easier to do with read only databases or even databases where you don't plan to change schema (but just process db records)
|
|
- add Connection::ping() or so, using http://dev.mysql.com/doc/mysql/en/mysql-ping.html
|
|
and use it after being idle for a while (eg. call it every minute; also add an option for the delay)
|
|
- Move ObjectStatus to kexidb. Merge with Object.
|
|
- Support for opening .sql files: just import it on opening to in-memory database and dump it back into
|
|
.sql text on exisitng. Add optional compressing.
|
|
- Add support for compressed kexi files (better keep the same .kexi extension instead of .kexiz)
|
|
- Implement tree structures using idea #5 described here http://www.depesz.com/various-sqltrees.php
|
|
(does pgsql require this hack?)
|
|
- double values are still rounded: consider storing them in memory as a decimal type
|
|
(e.g. using a special TQ_LLONG+decimalplace class); needed e.g. in KexiQueryParameters::getParameters()
|
|
- handle input mask using a special KexiDB::FieldInputMask class
|
|
--needed in forms (KexiDBLineEdit::setColumnInfo()) and table views
|
|
- add setValue() to cursors: this will REQUIRE a buffered cursor, since we cannot run sql
|
|
before fetching is done... See http://kexi-project.org/cgi-bin/irclogger_log/kexi?date=2006-08-03,Thu&sel=229#l225
|
|
- use ThreadWeaver library for threaded KexiDB version
|
|
- tables can use queries as a row source for lookup fields, what can lead to infinite recursion;
|
|
FIX this by either: 1) not allowing to use such table in a query (see kexi/to_fix/Ksiazka_adresowa2_recursive_query_deadlock.kexi)
|
|
or 2) delayed loading of query column
|
|
|
|
=== KexiDB Parser TODO ===
|
|
- add a method for replacing a single given table name in the statement (useful on table renames)
|
|
- add clever query relatins parsing
|
|
(needed for switching back to GUI editor from text mode)
|
|
- add flexible support for date/time constants
|
|
- store text position information (line, column) for every token so it can be used
|
|
in SQL editor to place cursor in case of errors
|
|
- add translation method for SQL operators to driver,
|
|
so SQLite can return "CONCAT" and mysql return "||" for concatenation oeprator, and so on
|
|
- improvement in terms of data recovery:
|
|
assume you're entering a long record and db connection is dead before saving...
|
|
the record could be buffered locally before closing Kexi application... and on next startup, re-sent.
|
|
This can work in simple cases (when complex transactions are not involved).
|
|
- report "ambiguous field name 'id'" error for ambiguous queries like "SELECT a.id, b.id FROM a, b ORDER BY id"
|
|
- add types checking to **Expr::validate()
|
|
- consider switching from bison/flex to http://www.antlr.org/
|
|
- make parser reentrant (for now we've used a workaround)
|
|
|
|
=== KexiDB MySQL Driver TODO ===
|
|
- use InnoDB instead of MyISAM tables because of transactions support
|
|
http://dev.mysql.com/doc/refman/5.0/en/ansi-diff-transactions.html
|
|
Kexi's MySQL driver uses MyISAM engine, but transaction support needs InnoDB
|
|
(there should be also an option available to set on CREATE TABLE, and on an default for CREATE DATABASE)
|
|
|
|
=== KexiDB PostgreSQL Driver TODO ===
|
|
- port to libpq
|
|
- set version information in drv_useDatabase()
|
|
There's connection_base::server_version() in libpqxx trunk -
|
|
http://thaiopensource.org/development/libpqxx/file/trunk/include/pqxx/connection_base.hxx
|
|
|
|
=== KEXIDB TESTS===
|
|
- add tests for DatabaseProperties
|
|
- add tests for PreparedStatement
|
|
- add tests for migration
|
|
|
|
=== Startup TODO ===
|
|
- reuse KexiNameWidget in KexiNewProjectWizard!
|
|
- use KPasswordDialog::disableCoreDumps() for security reasons
|
|
- IDEA for connection shortcuts:
|
|
Mysql Query Browser has a simple xml file defined:
|
|
http://dev.mysql.com/doc/query-browser/en/mysql-gui-appendix-store-connections.html
|
|
- allow to choose if the file should be locked (opened in EXCLUSIVE mode) or not
|
|
(THIS SHOULD BE DEFAULT BEHAVIOUR)
|
|
- (linux) remove stupid message 'Please select the file to open'
|
|
when opening exisiting server project and clicking 'OK'
|
|
- database files accessed remotely: make it work without copying a file to temp. dir.
|
|
(maybe even without copying entire file? - patching sqlite required)
|
|
- add "Open read only" checkbox to the file browser
|
|
(Driver::ReadOnlyConnection option already allows to open in read only mode)
|
|
|
|
=== CLI TODO ===
|
|
- add kexicmd as a symlink to kexi binary, for totally non-gui usage
|
|
- just drop all tables when database already exist
|
|
(so recreating database will be available even
|
|
if you have only access to one database).
|
|
- GRANT privileges for non-root (current?) user for newly created db
|
|
|
|
=== Mimetypes/icons TODO ===
|
|
- new mimetypes:
|
|
application/x-vnd.kexi.project.sqlite2
|
|
application/x-vnd.kexi.project.sqlite3
|
|
application/x-vnd.kexi.project.shortcut
|
|
other:
|
|
application/x-vnd.kexi.connections.shortcut
|
|
application/x-vnd.kexi.table.shortcut
|
|
application/x-vnd.kexi.query.shortcut
|
|
- remove x-vnd.kexi.desktop in tdelibs
|
|
- copy mimetypes and magic def. to tdelibs (keep it within Kexi for compat.)
|
|
- remake kexi mime type svg icons
|
|
- copy kexi mime icons to tdelibs, remove old one
|
|
** Ask SQLite devs for a possibility for adding a field to indicate kexi-sqlite
|
|
format without opening database
|
|
|
|
|
|
=== Docs TODO ===
|
|
|
|
-translate the current content from polish to english
|
|
-?? migrate english content to wiki format
|
|
-move polish content to .po translation file
|
|
-Add this to the preface http://encyklopedia.helion.pl/index.php/Kartotekowa_baza_danych

|
|
-- scripting, example: http://www.e-cen.pl/index.php?co=wiecej&id=22&dzial=6
|
|
- add chapters for:
|
|
-- simple printouts
|
|
-- "assign action" to a button
|
|
-- CSV import/export/copy/paste (csv import is explained on kexi@kde.org ML; 2007-03-23)
|
|

=== Interesting features ===
|
|
- Add random names/surnames generator: http://www.ruf.rice.edu/~pound/
|
|
Good for generating good-looking random data for a given table.
|
|
-- Autodetect 'name' columns or ask user to describe what he wants.
|
|
Comply with data validation rules.
|
|
-- use famous 'Lorem ipsum dolor sit amet...' test text for longtext types

---KexiBLOBBuffer::pixmap() shouldn't be used but data() should be used to create QMovie object
|
|
in each movie widget itself because even if the same QMovie was used in many movie widgets:
|
|
a) speeds can vary between movie widgets, b) different forms can be opended in different moments
|
|
so playing starts in different moments, c) one or more movies can be stopped while others not
|
|
---add following related properties: int playbackSpeed (in frames per second, 0==default),
|
|
bool autoStart (true==default), playbackControls (false==default), bool loopPlayback (true==default)
|
|
bool pauseAfterEnd (0==nothing==default)

Combo Box Editor
|

KEXIDB:
|
|
- ConnectionData: make local sockets default for unix, instead of tcp/ip
|
|
|
|
GENERAL:
|
|
- removed conflict between standalone and KOffice version by:
|
|
-- inserting "standalone" word into module names,
|
|
eg. kexidb_mysqldriver.so -> kexidb_mysqldriver_standalone.so
|
|
-- renaming kexi to kexi-standalone
|
|
- rename "data view mode" to "browse view mode" (as in Filemaker)
|
|
- add "File->Mail..." action (requires closing and copying of the sqlite file, if locked)
|
|
|
|
MARKETING:
|
|
- add "Created With Kexi" page and a link to it from k-p.org and kexi.pl
|
|
- when releasing new Kexi version publish: A first look at Kexi x.y" page, like this:
|
|
http://software.newsforge.com/article.pl?sid=05/09/28/1345228

|
- use sqlite3_column_decltype() http://sqlite.org/capi3ref.html#sqlite3_column_decltype
|
|
and sqlite3_column_name() to know column names and types.
|
|
Add reasonable case-insensitive mappings like "INTEGER|integer|INT|int" -> [integer]

|
- or: for import data from native-sqlite databases: use "pragma table_info(tablename)"
|
|
-- maybe also use "pragma table_info" for sanity checking, or more in kexidb driver??

|
- use "pragma user_version={32bit int}" (http://www.sqlite.org/pragma.html) to set, say, kexidb version.
