asyncio.get_running_loop() raises RuntimeError when emit() is called
from a thread without an active event loop (e.g. when the disk space
check in project_manager triggers a log.warning notification from a
threadpool worker).
This causes a 500 Internal Server Error on project creation/open when
disk usage is high, instead of the intended warning notification.
Wrap the emit loop in try/except RuntimeError so that notifications
are silently dropped when no event loop is available, rather than
crashing the request.
Fixes#2502Fixes#2505
As described in #2568 when multiple clients connect simultaneously, an excessive number of database pool connections are created. This leads to resource exhaustion and connection management issues.
We have introduced the pool_size and max_overflow parameters to better control the database connection pool.
These parameters ensure the database can handle a sufficient number of concurrent connections without over-allocating resources.
Added pool_size and max_overflow arguments to the database initialization.
This change overrides the default initialization configuration where the temporary fix was applied.

Most VNC clients use the Desktop name in their window title.
Currently this defaults to user@host which means all docker vnc
connections have identical window names of e.g.
SSVNC: gns3@gns3server
This uses the node name instead.
* Offset pci_device_id for network devices by 32 (formerly 4)
to reserve first 32 IDs for non-netdev devices
* This implies a new pci_bridge for the netdevs and
the pci_device_ids starting at 0 (using modulo)
* Fixes a bug in the creation of the qemu command
when the number of qemu pcie devices (storage_controller, disks, …)
was greater than 4 and the number of network devices
saturated the 32 pcie ids of the root bridge
causing qemu not to start.
