Encountered the same issue during a fresh setup: https://discuss.erpnext.com/t/v13-fresh-install-develop-socket-io-using-wrong-port/74562
The problem originates from the `socketio_client.js` file. During development, the `socket.io` client by default sends request to port 8000 but ideally it should've been 9000 (that's where it's actually running) since the latter is defined in `frappe.boot.socketio_port`. This is happening because the `jenv` variable `dev_server` is always being returned as 0.
In [this](0f7d8e7903/frappe/__init__.py (L237)) line, we are seting `frappe.local.dev_server` but in safe exec we are using `frappe._dev_server` as the source to populate the variable `dev_server` which eventually gets pushed to the `app.html` via `jinja`. (`frappe._dev_server` evaluates to `None`)
In `socketio_client`, we are using [this](0f7d8e7903/frappe/public/js/frappe/socketio_client.js (L112)) variable as a flag to decide whether or not `frappe.boot.socketio_port` should be the port that the `socket.io` client connects to.
- Added type hints to majority of most used functions in `utils/data.py`
- added overloads for functions whose output depends on input type. This helps A LOT if your LSP supports type narrowing (like pyright)
Example:
Same function with 3 diff singatures narrowed by input value.

* fix: misc fixes
local.x gets resetted on every request so switched to a simple dict
simplified is_val_used in set_next_val function for sequences
* chore: use multisql for sequence methods
* fix: fields not updating on form
* minor(base_input): removed unnecessary branching in update_input
* chore: remove prints and rename autoincremented_status_map
* chore: added proper type hint + comment + formatting
* fix: added searching in cast_name rather than handling it manually
* fix: share condition query + test_build_match_conditions
* fix: add cast_name to more places
* test: test for sequence
* fix: sequence functions
* fix: inherit frappetestcase
* minor: attach sequence methods to db context local
* chore: update sequence function names in Database
use frappe.db for sequences in naming.py
* fix: convert filename to str (for autoincremented doctypes)
* chore: better regex for modifying values for postgres
* minor: allow changing name column type (if no data is present in the doctype)
* refactor: validate_autoname
converted it to a simple function
enabled changing autoincrement autoname from customize form
* fix: use sql_ddl for change_column_type in postgres
* fix: use not null constraint in postgres when changing name type
* fix(test): updated test_autoincremented_doctype_transition with transitioning when no data is present
* fix(test): updated test_cast_name
probably messed up during rebase
* fix(test): used rollback upon error in transaction for postgres
* chore: use frappe.db.x methods for sequences
* minor: use temporary sequences in test
* minor: use generate_hash for sequence naming in sequence tests
* chore: replace sequence imports with frappe.db.x
* chore: move out casting name fields to a separate method
* refactor: cast_name
more explicit cases for casts and added docstring
* fix: added space in test_cast_name
* chore: fix linter
* chore: better naming for can_change_name_column_type
* chore: add comment for autoincremented_site_status_map
* chore: update/add docstrings
# Changes
- Introduces `subqry` class to use in where clause when there is a non-column condition. eg.
> .where(subqry(no_of_roles) == 0)
- Convert SQL queries to frappe.qb
# Testing
Functions with query refactors
- frappe.boot.get_user_pages_or_reports() -> Same output of `get_bootinfo()` as develop
- frappe.boot.get_unseen_notes() -> Forms the same query as develop
```sql
SELECT `name`,`title`,`content`,`notify_on_every_login`
FROM `tabNote` WHERE `notify_on_every_login`=1
AND `expire_notification_on`>'2022-03-30 01:10:53.393874'
AND (SELECT `nsb`.`user` FROM `tabNote Seen By` `nsb` WHERE `nsb`.`parent`=`tabNote`.`name`) NOT IN ('Administrator')
```
- frappe.installer._delete_doctypes() -> installed and uninsalled a dummy app to drop tables
### Not tested
- frappe.make_property_setter()
- frappe.realtime.get_pending_tasks_for_doc() [whitelist method]
- frappe.sessions.Session.start()
- frappe.twofactor.cache_2fa_data()
