coopstorage 1.7

Package for embedded storage systems

coopstorage

A Python library for embedded storage tracking — models physical storage locations, containers, and the channel-processor rules that govern how items flow in and out of each slot.

---

Overview

coopstorage provides:

• Locations — physical storage slots with configurable capacity, dimensions, and channel-processor type
• Containers — items stored at locations, each with a UoM, optional contents, and resource qualifiers
• Channel processors — pluggable rules that control which slots are addable/removable (FIFO, LIFO, OMNI, NoFlow, push variants, etc.)
• Transfer requests — declarative add/move/remove operations resolved against qualifier criteria
• Location qualifiers — filter locations by capacity, dimensions, UoM, resource type, occupied state, channel accessibility, and more
• Live visualizer — browser-based isometric/top-down view with real-time SSE updates, slot overlays, UOM icons, and a legend

Channel Processor Types

Type	Add	Remove	Flow
AllAvailableChannelProcessor	any empty slot	any occupied slot	none
AllAvailableFlowChannelProcessor	any empty slot	any occupied slot	forward
AllAvailableFlowBackwardChannelProcessor	any empty slot	any occupied slot	backward
FIFOFlowChannelProcessor	back of queue	front (oldest)	forward
FIFOFlowBackwardChannelProcessor	front (push)	front (oldest)	backward
FIFONoFlowChannelProcessor	deepest open slot	deepest occupied (oldest)	none
FIFONoFlowPushChannelProcessor	slot 0 (push)	deepest occupied (oldest)	none
LIFOFlowChannelProcessor	back of queue	front (newest)	forward
LIFOFlowBackwardChannelProcessor	front (push)	front (newest)	backward
LIFONoFlowChannelProcessor	deepest open slot	shallowest occupied (newest)	none

Quick Start

from coopstorage.storage.loc_load.storage import Storage
from coopstorage.storage.loc_load.location import Location
import coopstorage.storage.loc_load.dcs as dcs
import coopstorage.storage.loc_load.channel_processors as cps
from coopstorage.storage.loc_load.qualifiers import LocationQualifier
from coopstorage.storage.loc_load.transferRequest import TransferRequestCriteria

# Build storage with two locations
loc_a = Location(
    id='A',
    location_meta=dcs.LocationMeta(
        dims=(10, 10, 5),
        channel_processor=cps.FIFOFlowChannelProcessor(),
        capacity=5,
    ),
    coords=(0, 0, 0),
)
loc_b = Location(
    id='B',
    location_meta=dcs.LocationMeta(
        dims=(10, 10, 5),
        channel_processor=cps.LIFOFlowBackwardChannelProcessor(),
        capacity=5,
    ),
    coords=(15, 0, 0),
)

storage = Storage(locs=[loc_a, loc_b])

# Add a container to the first available location
storage.handle_transfer_requests([
    TransferRequestCriteria(
        new_container=dcs.Container(id='C001'),
        dest_loc_query_args=LocationQualifier(at_least_capacity=1, has_addable_position=True),
    )
])

Location Qualifiers

LocationQualifier filters candidate locations during transfer resolution:

from coopstorage.storage.loc_load.qualifiers import LocationQualifier, ContainerQualifier
from cooptools.qualifiers import PatternMatchQualifier, WhiteBlackListQualifier

# Destination: must have capacity, an accessible drop slot, and accept the container's UoM
LocationQualifier(
    at_least_capacity=1,
    has_addable_position=True,
)

# Source: must contain a container matching a pattern
LocationQualifier(
    has_all_containers=[ContainerQualifier(pattern=PatternMatchQualifier(regex='^C00'))]
)

Key parameters:

Parameter	Description
at_least_capacity	Minimum number of free slots
has_addable_position	Channel processor has an accessible drop position
is_occupied	True/False filter on whether any container is present
has_any_containers	At least one container satisfies any of the given qualifiers
has_all_containers	For each qualifier, at least one container satisfies it
has_content	Total qty of a resource/UoM across all containers meets a minimum
uom_qualifier / ignore_uom_qualifier	Container UoM must be allowed by location's whitelist
resource_type_qualifier / ignore_resource_type_qualifier	Container resource types must be allowed
min_slot_dims	All slot dimensions must be >= this
reserved	Filter on reservation state

Visualizer

Start a live browser visualizer alongside a benchmark or simulation:

# Showcase: one of each channel processor type, lock-step add/remove
python run_viz_benchmark.py --mode showcase

# Continuous randomized simulation
python run_viz_benchmark.py --mode sim --config small

# Fixed benchmark workload
python run_viz_benchmark.py --mode benchmark --config medium

# Options
python run_viz_benchmark.py --delay 0.05 --log-level DEBUG --port 1219

The visualizer is served at http://localhost:1219/static/index.html.

Slot overlays:

Color	Meaning
Green fill	Occupied
Grey fill	Available
Blue outline	Droppable (addable position)
Purple outline	Retrievable (removable position)

Each container label shows a unique icon per UoM type with a live legend.
