- Implement an alternative solution for handling sorted columns without usage of SMDBGrid's sortcolumns. Move relevant structures and functions from data_sorting.pas to childwin.pas and use them in both units.
- Upgrade some code parts to use WideStrings instead of Strings so they don't break with the new grid.
- Use Grid.OnDrawDataCell as an alternative to Grid.OnGetCellParams as the latter one is a feature of SMDBGrid
- Cosmetic: enhance screen real estate in viewdata()
* Bugfix: When methods are called recursively, they should push/pop altered event handlers on a LIFO stack instead of blindly setting and unsetting them.
* Cosmetic: Reclaim screen real estate in ReadDatabasesAndTables().
- File logging can be activated in preferences dialog, by default of course NOT active.
- One file per session is written to [Documents and settings]\[username]\Application data\HeidiSQL\Sessionlogs\
- Filename pattern: "[session name] [zeropadded session nr].log"
- Fetch more descriptive CSIDL_* constants for system folders from ShlObj unit rather than hardcoded hex values
- Give the user a prettier confirmation message with listed tables to drop.
- Add documentation
- Drop large WITH .. DO statement
- Correctly call refresh-procedures
- Consistency:
- Move all global preferences vars from mainform to childwin.
- Get rid of unused legacy vars NativeFieldTypes + LanguageOffset
- Readability:
- Add documentation
- Prefix preferences vars with "pref"
- Get rid of WITH .. DO statements
Additionally/Sideeffects:
- Fix vstFreeNode to delete the item from the array, not only free the item itself
- Change/Rename GetSelectedNodesFromVT to GetVTCaptions and give it the ability to return all captions, not only the selected. This function is very useful now and saves writing much redundant code.
A table with 500 columns needed 3 seconds to display in the TSortListView, now that takes less than a half second.
Additionally/Side effects:
- TVTreeData structure moved to helpers.pas to be able to use it in new function GetSelectedNodesFromVT.
- ListTablesEditing dropped. We don't need to disable any shortcut there because there is none set.
- Avoid potential AVs when accessing not created items in TVTreeData.Captions
- popupmenu in query memo
- query helpers
- SynCompletionProposal
Drops function.txt and parser for that file.
Pros:
- No dependency on this file anymore
- Much easier and safer coding
- File-parsing no longer needed
Notes:
The old function.txt was meant to be editable and extensible for users but I never saw or heard anyone who does that, most likely because it wasn't documented. Another problem was that the file resided in the programs-directory, where only administrators have write-access, so in these cases it couldn't be edited anyway.
The PHP file in /extras can be used for creating an up-to-date list for mysql.pas .
As not all functions of the new list are available in all mysql-versions, it would be the best if we would fetch the list by the use of HELP commands. Contra: Would result in poor performancing popupmenu and many servers don't have the help-tables filled.
As a benefit, function.txt is read into 3 stringlists at startup now: Names, Declarations and Descriptions. Used in SynCompletionProposal and to fill the above mentioned helpers-list.
Also fixes a minor issue in SynMemoQueryDragOver using an unset "Accept" var.
* Remove feature: columns listed in tree view (helps fix repeated queries; need to cache these and move to different GUI location)
* Remove feature: SELECT COUNT(*) on all tables with MySQL < 3.23 (performance killer)
* Add feature: Cache table lists for tree view (improves performance and fixes repeated queries)
* Add feature: Master refresh button clears entire table list cache.
* Add feature: Refresh button in table list view popup clear table list cache for database being viewed.
* Add feature: Restore active database after user queries.
