I'm writting AJAX part now. Have a look at this commit:
https://github.com/WhaleWatching/phpmyadmin/commit/a382070ee42b72474842d20e8...
See my comment on it: For get response data I add a param, run between requestHandler
and
responseHandler.
As I understand, this mid-handler is your responsehandler that subsequently makes a call to the generic responsehandler of ajax.js.
So it
is not a real custom handler (that requests + handles response
independent
of the generic one)
Also, as I understand from your code, the proposed console would
store a
log of run queries and on running a query from console, the results
will be
displayed in the same way as happens when running a query from SQL
tab.
Right ?
Sometimes people'll run queries on console while they're browsing other pages, not SQL tab.
As per this understanding, you need a real custom handler because executing SQL and handling its response in PMA involves many custom
checks
and calls not only at response stage but also at request stage. For
ex:-
checkSqlQuery()
Sorry I don't get this :), just run it if some errors we can wait response to tell users
- bookmark handling
Bookmark handling will use another functions and send another AJAX request, old way is not good enough.
reloading navigation for certain queries
reloading navigation, global handlers take this job is better
- refreshing main panel for certain queries
Do you main #page_content ?
- triggering grid edit for results
etc. see in sql.js near $("#sqlqueryform.ajax").live('submit',
function
(event) {
I have noticed this handler.
Or did you plan to duplicate above checks and calls into your
midhandler?
No, midhandler just get result and append to console corresponding message(e.g. shows under query string "SELECT
- FROM `mysql`.`user`")
Ok, so you plan to display query results in the console itself. I misunderstood some details from your proposal and thought that query results will be displayed in the main panel and query logs in the console. My previous reply was according to that understanding. Also, please tell me about the following details..
- I am still unclear about warnings etc. that we display for certain
queries like DROP, will we warn the user when executing such queries from console? Or would it be totally like mysql console?
- Also in case user puts a USE query in console, do we change the selected
database and update the navigation and main panel? Same will be required for ALTER queries etc.. Here I am pointing to the overall relation and synchronization between console and rest of the application.
These features can be added later, before execute there's PMA_console.execute(), after execute there's midHandler.
- And would you store the sql query logs only or the sql results history
as well? I think as the results may change at any time, storing queries only should be fine.
Yeah, data may change any time, but we still can store results, users know when a query should be re executed.
Alright, I'll change my design, store queries only, with bookmarks and history.
