* Hide new menuitems when SynMemoFilter is focused.
* Call SynMemoQuery.OnChange in popupQuery.Popup to ensure various menuitems are dis-/enabled
* Disable "Clear" item when memo is empty
* Bring items in a better, usable order
* Nuke dependency of hardcoded itemcount in code for SQL functions: "popupQuery.Items[i+13].Add(mi);"
* Add useful actions:
+ Insert file at cursor
+ Save selection to file
+ Save as snippet
+ Save selection as snippet
* Assign procedures for menuLoad + menuSave at designtime, not at runtime (which made sense in a MDI mechanism)
* Minor optimization of detecting selected text in SynMemo
1. When user opens a file which is bigger than LOAD_SIZE (currently 5M), ask what to do
2. User can normally open the file, cancel, or use the new mechanism:
3. Load a chunk of LOAD_SIZE of SQL into memory
4. Split chunk with parseSQL into single queries
5. Run queries and go on with 3.
parseSQL is the bottleneck here, very CPU consuming, as it has to take care of different comment-styles and delimiters. So, the above strategy effected a good compromise regarding overall performance on different tests with worst case SQL files:
- "Wide" table exports with many big sized fields => long lines
- "Narrow" table exports with only one mini-sized field, extended INSERTs => short lines
Especially in the latter case it avoids to cause a hellfire of parseSQL-calls
Still seems to have some memory leaks somewhere.
Bugfix: FetchActiveDb...() is a helper function, do not try to handle exceptions as it leads to AVs.
Bugfix: ShowTableProperties() is a helper function, do not try to handle exceptions as it leads to AVs.
Bugfix: AV in ShowProcessList when disconnected.
Bugfix: AV in ShowVariablesAndProcesses when disconnected. (Something tells me it could be better to let the default for HandleErrors be 'false', a lot of these seems to pop up during testing...)
Bugfix: Connected time counter did not stop when connection got dropped.
Bugfix: Uptime counter did not stop when connection got dropped.
viewdata(): Use standard method of fetching data to get rid of redundant code.
...BeforeSendingSql(): Remove now redundant code.
Side-effect: Needed to change some editor-related shortcuts so they don't trigger their corresponding menu-commands from popupTableGrid when the user presses them at the time the column name gets edited:
- Call field editor : Now "Alt+Enter", was "Enter"
- Drop field : Now "Ctrl+Del", was "Del"
This has one positive side effect: ViewData no longer re-saves an ORDERCLAUSE to registry after it has been read. At the same time the ORDERCLAUSE is read everytime when grid is filled, not only the first time. Those changes were needed to be able to apply an ORDERCLAUSE which was generated and saved by the new dialog.
Left for later: Moving order-columns up and down. Tested that with a TUpDown which seems to ignore clicks sometimes and then doesn't fire OnClick.
* Add feature: Read and write all options from / to registry, using some existing CSV-options
* Fix bug: Correct escaping for db, table, columns, values for terminator, etc.
* Style change: Drop superflous checkboxes from checkbox/edit pairs to save clicks. Checking for empty edits has the same effect.
* Style change: Don't convert backslashes in filename to slashes. No need to take care of escaping, esc() does that better.
- 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.
