Hi Akshay/Khushboo,
I have few suggestions/questions for the attached patch:
1. Code like SchemaDiffRegistry('server', ServerNode) should be replaced
with SSchemaDiffRegistry(ServerModule.NODE_TYPE, ServerNode)
2. The variables return_ajax_response, only_sql, json_resp as far as I
understood are similar. Can we have same var name everywhere ?
3. Remove commented code -
web/pgadmin/browser/server_groups/servers/databases/schemas/tables/__init__.py
-> get_sql_from_table_diff
4. In
web/pgadmin/browser/server_groups/servers/databases/schemas/tables/__init__.py
-> fetch_tables - keys_to_remove is passed. How is it different from
keys_to_ignore used at other places ?
5. web/pgadmin/tools/schema_diff/__init__.py
-> check_version_compatibility has hardcoded version numbers. Can we
use get_version_mapping_directories from
web/pgadmin/utils/versioned_template_loader.py ?
6. Rename .reallyHidden to .really-hidden
7. CSS class #schema-diff-grid -> background: white; - hardcoded color
can be changed to use $color-bg instead. Also use rem or px for -
font-size: 9pt.
8. .slick-group-toggle.collapsed, .slick-group-toggle.expanded - svgs
are not required. Font awesome has the icons. refer - .obj_properties
.collapsed .caret::before.
9. In web/pgadmin/tools/schema_diff/static/js/schema_diff.backform.js ->
formatNode - Appends can be avoided and formed in a single statement.
+ } else {
+ return $('<span></span>').append(
+ $('<span></span>', {
+ class: 'wcTabIcon ' + optimage,
+ })
+ ).append($('<span></span>').text(opt.text));
+ }
+};
10. In web/pgadmin/tools/schema_diff/static/js/schema_diff.backform.js
-> fetchData - We should not use async = false.
+ $.ajax({
+ async: false,
+ url: url,
+ })
11. In web/pgadmin/tools/schema_diff/static/js/schema_diff_ui.js -
Use 'sources/window' - pgWindow.
+ let preferences = (window.opener !== null) ?
window.opener.pgAdmin.Browser.get_preferences_for_module('schema_diff') :
window.top.pgAdmin.Browser.get_preferences_for_module('schema_diff');
12. In web/pgadmin/tools/schema_diff/static/js/schema_diff_ui.js - Use
map instead of for loop. It will also remove the sel_rows_data.push. will
be helpfull in large data.
+ for (var row = 0; row < sel_rows.length; row++) {
+ let data = self.grid.getData().getItem(sel_rows[row]);
+
+ if (data.type) {
+ let tmp_data = {
+ 'node_type': data.type,
+ 'source_oid': parseInt(data.oid, 10),
+ 'target_oid': parseInt(data.oid, 10),
+ 'comp_status': data.status,
+ };
+
+ if(data.status && (data.status.toLowerCase() == 'different'
|| data.status.toLowerCase() == 'identical')) {
+ tmp_data['target_oid'] = data.target_oid;
+ }
+ sel_rows_data.push(tmp_data);
+ }
+ }
+
+ url_params['sel_rows'] = sel_rows_data;
13. In web/pgadmin/tools/schema_diff/static/js/schema_diff_ui.js -Are we
doing anything to handle failure.
+ connect_database(server_id, db_id, callback) {
+ var url = url_for('schema_diff.connect_database', {'sid':
server_id, 'did': db_id});
+ $.post(url)
+ .done(function(res) {
+ if (res.success && res.data) {
+ callback(res.data);
+ }
+ })
+ .fail(function() {
+ // Fail
+ });
+
+ }
14. As you've added a completely different function for connect_server,
I would suggest to rename dlgServerPass to a different name to avoid
conflict with existing dlgServerPass in server.js
+ if (!Alertify.dlgServerPass) {
+ Alertify.dialog('dlgServerPass', function factory() {
15. Generate script does not work if pgAdmin opened in iframe. Iframes
are used by tools like Katacoda.

16. Comparing objects loader is not attached to DDL Comparison panel.

17. Filter icon and Generate script icon size are different. Also change
icons CSS to use font-icon. You can refer icons from sqleditor.

*The fetch_objects_to_compare function used in each node uses loop to fetch
data. Although it is working for now, but I would suggest using bulk fetch
nodes instead of looping through all the nodes one by one.*
