# exposed-0001: mapMissingColumnStatements — O(N×M) list scan in schema migration
|
||||
|
||||
**Severity:** HIGH
|
||||
**File:** exposed-core/src/main/kotlin/org/jetbrains/exposed/v1/core/SchemaUtilityApi.kt
|
||||
**Lines:** 80–89
|
||||
**Status:** PATCHED
|
||||
|
||||
## Description
|
||||
|
||||
`Table.mapMissingColumnStatementsTo()` is called during every `SchemaUtils.createMissingTablesAndColumns()` invocation —
|
||||
the standard Exposed migration path. It contains two nested O(N) list scans:
|
||||
|
||||
1. **Line 80–83**: For each of the N table columns, `existingColumns.find { column.nameUnquoted().equals(it.name, true) }`
|
||||
performs a full linear scan over M existing-column metadata records. Total: O(N×M).
|
||||
|
||||
2. **Lines 88–90**: `indices.filter { index -> index.columns.any { missingTableColumns.contains(it) } }` —
|
||||
`missingTableColumns` is a `List<Column<*>>`, so `.contains()` is O(M). With I indices each having up to C columns
|
||||
this is O(I×C×M).
|
||||
|
||||
For a table with 50 columns and 50 existing metadata rows this is 2 500 equality checks; with 20 indices the
|
||||
secondary loop adds another 1 000 checks. Both grow as O(N²) as schema size increases.
|
||||
|
||||
## Root Cause
|
||||
|
||||
`existingColumns` is passed in as `List<ColumnMetadata>` and `missingTableColumns` is derived as a `List<Column<*>>`.
|
||||
Neither is converted to a hash-based structure before the loops begin, so every membership test is O(N).
|
||||
|
||||
## Fix
|
||||
|
||||
Pre-build a `HashMap<String, ColumnMetadata>` keyed by lowercase column name before the loop, enabling O(1) lookup.
|
||||
Convert `missingTableColumns` to a `HashSet<Column<*>>` before the index-filter loop.
|
||||
|
||||
```kotlin
|
||||
// Before (O(N×M)):
|
||||
val existingTableColumns = columns.mapNotNull { column ->
|
||||
val existingColumn = existingColumns.find { column.nameUnquoted().equals(it.name, true) }
|
||||
if (existingColumn != null) column to existingColumn else null
|
||||
}.toMap()
|
||||
val missingTableColumns = columns.filter { it !in existingTableColumns }
|
||||
...
|
||||
indices.filter { index ->
|
||||
index.columns.any { missingTableColumns.contains(it) }
|
||||
}
|
||||
|
||||
// After (O(N)):
|
||||
val existingByName = existingColumns.associateBy { it.name.lowercase() }
|
||||
val existingTableColumns = columns.mapNotNull { column ->
|
||||
val existingColumn = existingByName[column.nameUnquoted().lowercase()]
|
||||
if (existingColumn != null) column to existingColumn else null
|
||||
}.toMap()
|
||||
val missingTableColumns = columns.filter { it !in existingTableColumns }
|
||||
val missingTableColumnsSet = missingTableColumns.toHashSet()
|
||||
...
|
||||
indices.filter { index ->
|
||||
index.columns.any { missingTableColumnsSet.contains(it) }
|
||||
}
|
||||
```
|
||||
|
||||

# exposed-0002: isAKeyword — O(K) linear keyword scan per identifier (uncached path)
|
||||
|
||||
**Severity:** MEDIUM
|
||||
**File:** exposed-core/src/main/kotlin/org/jetbrains/exposed/v1/core/statements/api/IdentifierManagerApi.kt
|
||||
**Line:** 72
|
||||
**Status:** PATCHED
|
||||
|
||||
## Description
|
||||
|
||||
`isAKeyword()` is called on every identifier that passes through `needQuotes()`, `shouldQuoteIdentifier()`,
|
||||
and `inProperCase()`. These are called during SQL generation for every column reference, table name, and alias
|
||||
in every query.
|
||||
|
||||
The `keywords` lazy property is constructed as:
|
||||
|
||||
```kotlin
|
||||
val keywords by lazy {
|
||||
ANSI_SQL_2003_KEYWORDS + VENDORS_KEYWORDS[currentDialect.name].orEmpty() + dbKeywords()
|
||||
}
|
||||
```
|
||||
|
||||
`ANSI_SQL_2003_KEYWORDS` is a `Set<String>` (~500 entries). `Set + List` in Kotlin produces a `Set`, so
|
||||
`keywords` ends up as a `Set`. However line 72 uses `.any { this.equals(it, true) }` — a case-insensitive
|
||||
equality predicate — which forces full iteration. A `HashSet` `.contains()` would be O(1), but case-folding
|
||||
breaks the default hash lookup.
|
||||
|
||||
The `checkedKeywordsCache` mitigates repeated hits for the same identifier string, but on every cache miss
|
||||
(new identifier encountered for the first time) the full ~500-element list is linearly scanned.
|
||||
|
||||
In a schema with 500 distinct column/table names, startup generates 500 cache misses × 500 keyword checks = 250 000
|
||||
string comparisons for keyword detection alone.
|
||||
|
||||
## Root Cause
|
||||
|
||||
No case-insensitive set structure is pre-built. The `.any {}` predicate bypasses `HashSet`'s O(1) hash path.
|
||||
|
||||
## Fix
|
||||
|
||||
Pre-build a `HashSet<String>` of lowercased keywords at lazy-init time so every lookup is O(1):
|
||||
|
||||
```kotlin
|
||||
// Before (O(K) per cache miss):
|
||||
val keywords by lazy {
|
||||
ANSI_SQL_2003_KEYWORDS + VENDORS_KEYWORDS[currentDialect.name].orEmpty() + dbKeywords()
|
||||
}
|
||||
|
||||
private fun String.isAKeyword(): Boolean = checkedKeywordsCache.getOrPut(lowercase()) {
|
||||
keywords.any { this.equals(it, true) }
|
||||
}
|
||||
|
||||
// After (O(1) per cache miss):
|
||||
val keywords by lazy {
|
||||
ANSI_SQL_2003_KEYWORDS + VENDORS_KEYWORDS[currentDialect.name].orEmpty() + dbKeywords()
|
||||
}
|
||||
|
||||
private val keywordsLower: Set<String> by lazy {
|
||||
keywords.mapTo(HashSet()) { it.lowercase() }
|
||||
}
|
||||
|
||||
private fun String.isAKeyword(): Boolean = checkedKeywordsCache.getOrPut(lowercase()) {
|
||||
lowercase() in keywordsLower
|
||||
}
|
||||
```
|
||||
|
||||

|
||||

||||

# exposed-0003: Table.clone — O(N²) repeated List allocation in property filter
|
||||
|
||||
**Severity:** MEDIUM
|
||||
**File:** exposed-core/src/main/kotlin/org/jetbrains/exposed/v1/core/Table.kt
|
||||
**Line:** 1686
|
||||
**Status:** PATCHED
|
||||
|
||||
## Description
|
||||
|
||||
The private `T.clone()` utility in `Table` is used internally when cloning column objects (e.g., during
|
||||
alias creation and column type mutation). It contains:
|
||||
|
||||
```kotlin
|
||||
val allValues = memberProperties
|
||||
.filter { it in mutableProperties || it.name in consParams.map(KParameter::name) }
|
||||
.associate { it.name to (replaceArgs[it] ?: it.get(this@clone)) }
|
||||
```
|
||||
|
||||
The predicate `it.name in consParams.map(KParameter::name)` is evaluated for every element of
|
||||
`memberProperties`. Each evaluation calls `.map(KParameter::name)`, allocating a fresh `List<String?>`.
|
||||
For a class with P properties and C constructor parameters, this is P × C string comparisons plus P list
|
||||
allocations.
|
||||
|
||||
`Column` classes can have 10–20 properties; this is called once per column per alias/clone operation. In a
|
||||
query with 50 aliased columns this function runs 50 times, each time performing up to 400 string comparisons
|
||||
with 20 temporary `List` allocations per call — 20 000 comparisons and 1 000 heap allocations total.
|
||||
|
||||
## Root Cause
|
||||
|
||||
`consParams.map(KParameter::name)` is a lambda-captured expression inside the `.filter {}` predicate.
|
||||
Kotlin does not hoist it; it runs inside the hot loop.
|
||||
|
||||
## Fix
|
||||
|
||||
Pre-compute the parameter name set once, outside the filter:
|
||||
|
||||
```kotlin
|
||||
// Before (O(P×C) with P list allocations):
|
||||
val allValues = memberProperties
|
||||
.filter { it in mutableProperties || it.name in consParams.map(KParameter::name) }
|
||||
.associate { it.name to (replaceArgs[it] ?: it.get(this@clone)) }
|
||||
|
||||
// After (O(P) with O(1) lookup):
|
||||
val consParamNames = consParams.mapTo(HashSet()) { it.name }
|
||||
val allValues = memberProperties
|
||||
.filter { it in mutableProperties || it.name in consParamNames }
|
||||
.associate { it.name to (replaceArgs[it] ?: it.get(this@clone)) }
|
||||
```
|
||||
|
||||

# rails-0001: Preloader::Batch — O(N×F) future_tables Array#include? per loader per batch round
|
||||
|
||||
**Severity:** HIGH
|
||||
**File:** activerecord/lib/active_record/associations/preloader/batch.rb
|
||||
**Line:** 24
|
||||
**Status:** PATCHED
|
||||
|
||||
## Description
|
||||
|
||||
`Preloader::Batch#call` builds `future_tables` as an Array (via `.map(&:table_name).uniq`)
|
||||
and then calls `future_tables.include?(l.table_name)` inside `loaders.reject { ... }`.
|
||||
This is O(L×F) per batch round where L = loader count and F = future_table count.
|
||||
With D-depth association trees the outer `until branches.empty?` loop runs D times,
|
||||
making the total O(D×L×F).
|
||||
|
||||
## Root Cause
|
||||
|
||||
`Array#uniq` returns an Array, not a Set. The subsequent `.include?` call is O(F) per
|
||||
element. In eager-loading a deeply nested association tree with many tables, both L and F
|
||||
grow with the model graph, producing quadratic work per query.
|
||||
|
||||
## Fix
|
||||
|
||||
Change `.uniq` to `.to_set` so that `future_tables.include?` is O(1).
|
||||
|
||||
```ruby
|
||||
# BEFORE
|
||||
end.map(&:table_name).uniq
|
||||
|
||||
# AFTER
|
||||
end.map(&:table_name).to_set

**Severity:** HIGH

|

**Line:** ~450 (CallbackChain#skip)
|
||||
**Status:** PATCHED
|
||||
|
||||
## Description
|
||||
|
||||
`skip_callback` iterates `filters.each` across all descendants, and for each filter calls
|
||||
`chain.index(callback)` — an O(C) linear scan through the chain Array. With F filters and
|
||||
C callbacks per descendant class and D descendants, total complexity is O(D×F×C).
|
||||
In apps with deep inheritance hierarchies and many callbacks this becomes O(n³).
|
||||
|
||||
## Root Cause
|
||||
|
||||
`Array#index` is a linear scan. The chain is rebuilt on every `skip_callback` call rather
|
||||
than maintaining a pre-built position map.
|
||||
|
||||
## Fix
|
||||
|
||||
Pre-build a `position_map = chain.each_with_index.to_h` once before the filters loop so
|
||||
each lookup is O(1).

# rails-0003: Enumerable#excluding — O(N×E) elements Array#include? in reject loop
|

|

**Severity:** MEDIUM
|

**File:** activesupport/lib/active_support/core_ext/enumerable.rb
|

**Line:** ~35 (excluding method)
|
||||
**Status:** PATCHED
|
||||
|
||||
## Description
|
||||
|
||||
`Enumerable#excluding` is implemented as:
|
||||
```ruby
|
||||
reject { |element| elements.include?(element) }
|
||||
```
|
||||
where `elements` is an Array. The outer `reject` iterates N receiver elements; for each,
|
||||
`Array#include?` scans the full E-element exclusion list — O(N×E) total.
|
||||
|
||||
This method is used in AR query builders, relation scoping, and test helpers, so the
|
||||
O(N×E) cost is paid frequently with real model collections.
|
||||
|
||||
## Root Cause
|
||||
|
||||
`elements` is passed as a splat Array and used directly with `Array#include?` rather than
|
||||
being materialized as a Set before the iteration begins.
|
||||
|
||||
## Fix
|
||||
|
||||
```ruby
|
||||
# BEFORE
|
||||
reject { |element| elements.include?(element) }
|
||||
|
||||

## Description
|
||||
|
||||
`Enumerable#in_order_of` sorts a collection by the position of each element in a `series`
|
||||
Array using `sort_by { |e| series.index(e) }`. `Array#index` is O(S) per call, and
|
||||
`sort_by` invokes the block O(N log N) times — total O(N log N × S).
|
||||
|
||||
Used in ActiveRecord attribute ordering and result set sorting, so called on every
|
||||
query result set that uses custom ordering.
|
||||
|
||||
## Root Cause
|
||||
|
||||
`series.index(value)` is an O(S) linear scan called inside a `sort_by` comparator block
|
||||
that executes O(N log N) times. No position index is pre-built.

|

## Description
|

|

|
||||
costs O(I×C).
|
||||
|
||||
This runs once per table during `db:schema:dump`, so with T tables the total is
|
||||
O(T × I × C). In large schemas with many tables and constraints this is measurably slow.
|
||||
|
||||
## Root Cause
|

## Description
|
||||
|
||||
When loading PostgreSQL index metadata, `include_columns` is built as an Array by
|

splitting and mapping the include clause. Then `columns.reject! { |c| include_columns.include?(c) }`
|
||||
scans the full include_columns Array for each column — O(C×I) where C = column count
|
||||
and I = include_column count.
|
||||
|
||||
This runs during every schema reflection call (e.g., `connection.indexes(table_name)`),
|
||||
which is invoked on every model class load and on every `db:schema:dump`.
|
||||
|
||||
## Root Cause
|

|

`include.split(",").map { ... }` returns an Array. The subsequent `Array#include?` in the

## Description
|
||||
|
||||
`ActiveSupport.run_load_hooks` checks `@run_once[name].include?(block)` before running
|
||||
each block. `@run_once[name]` is an Array, so each check is O(R) where R = number of
|
||||
already-run-once hooks. With H hooks fired during boot and R growing per hook, total
|
||||
cost is O(H×R) — quadratic in the number of once-only hooks.
|
||||
|
||||
This runs during Rails application boot for every initializer and engine that uses
|
||||
`run_load_hooks`.
|
||||
|
||||
## Root Cause
|
||||
|
||||
`@run_once[name]` is initialized as `[]` and accumulated with `<<`. The `include?` check
|
||||
against this growing Array is O(R) per call.
|
||||
|
||||
## Fix

|
||||
|
||||
## Description
|
||||
|
||||
When defining an enum, `_enum_methods_module` iterates over all enum values with
|
||||
`pairs.each` and calls `value_method_names.include?(value_method_alias)` to check for
|
||||
alias conflicts. `value_method_names` is an Array that grows as each value is processed —
|
||||
O(E) scan per value, O(E²) total for E enum values.
|
||||
|
||||
This runs at class load time for every model that declares an enum, so with many models
|
||||
and large enums it contributes to slow boot times.
|
||||
|
||||
## Root Cause
|
||||
|
||||
`value_method_names` is an Array accumulating method names. The `include?` check is O(E)

||||
per iteration.

## Description
|
||||
|

`FilterAttributeHandler#apply_filter` is called once per sensitive attribute per model

```ruby

app.config.filter_parameters << filter unless app.config.filter_parameters.include?(filter)
|

```
|
||||

`app.config.filter_parameters` is an Array (initialized as `[]` in railties). Each
|
||||
`.include?(filter)` call is O(F) where F is the current size of `filter_parameters`.
|

With A total sensitive attributes across all models and F growing as attributes are added,

the application.

This is the same structural pattern as rails-0010 (encryption variant) and runs at every
|
||||
app boot for all models using `has_secure_password`, `attr_encrypted`, or manual
|
||||
`filter_attributes` declarations.
|
||||
|
||||
## Root Cause
|
||||
|
||||
`filter_parameters` is a plain Array. The deduplication guard `include?` is O(F) per
|
||||
insertion rather than using a Set or Hash for O(1) membership.
|
||||
|
||||
## Fix
|
||||
|
||||
Pre-build a `Set` mirror of `filter_parameters` for O(1) membership checks, or change
|
||||
the underlying storage to a `Set`:
|
||||
|
||||
```ruby
|
||||
# BEFORE (filter_attribute_handler.rb:69)
|
||||
app.config.filter_parameters << filter unless app.config.filter_parameters.include?(filter)
|
||||
|
||||
# AFTER
|
||||
existing = app.config.filter_parameters.to_set
|
||||
list.each do |attribute|
|
||||
next if klass.abstract_class? || klass == Base
|
||||
klass_name = klass.name ? klass.model_name.element : nil
|
||||
filter = [klass_name, attribute.to_s].compact.join(".")
|

|

app.config.filter_parameters << filter
|

existing << filter

# rails-0010: Encryption::AutoFilteredParameters — O(A×F+A×X) Array#include? + Array#find per encrypted attribute
|

|

**Severity:** MEDIUM
|
||||
**File:** activerecord/lib/active_record/encryption/auto_filtered_parameters.rb
|

**Lines:** 56, 62
|
||||
**Status:** PATCHED
|
||||
|
||||
## Description
|
||||
|
||||
`AutoFilteredParameters#apply_filter` is called for every encrypted attribute on every
|
||||
model class. It contains two O(n) scans per call:
|
||||
|
||||
**Line 56:** Array `include?` on `filter_parameters`:
|
||||
```ruby
|
||||
app.config.filter_parameters << filter unless app.config.filter_parameters.include?(filter)
|
||||
```
|
||||
|
||||
**Line 62:** Array `find` on `excluded_from_filter_parameters`:
|
||||
```ruby
|
||||
ActiveRecord::Encryption.config.excluded_from_filter_parameters.find { |excluded_filter|
|
||||
excluded_filter.to_s == filter_parameter
|
||||
}
|
||||
```
|
||||
|
||||
Both lists are Arrays. With A encrypted attributes across all models, F existing
|
||||
`filter_parameters` entries, and X `excluded_from_filter_parameters` entries:
|
||||
- Total cost: O(A×F + A×X)
|
||||
|
||||
This runs at every app boot for all models using `encrypts`.
|
||||
|
||||
## Root Cause
|
||||
|
||||
Both `filter_parameters` (Array) and `excluded_from_filter_parameters` (Array) are scanned
|
||||
linearly on every encrypted attribute registration. Neither is pre-materialized as a Set.
|
||||
|
||||
## Fix
|
||||
|
||||
```ruby
|
||||
# BEFORE (line 62)
|
||||
def excluded_from_filter_parameters?(filter_parameter)
|
||||
ActiveRecord::Encryption.config.excluded_from_filter_parameters.find { |excluded_filter|
|
||||
excluded_filter.to_s == filter_parameter
|
||||
}
|
||||
end
|
||||
|
||||
# AFTER
|
||||
def excluded_from_filter_parameters?(filter_parameter)
|
||||
@excluded_set ||= ActiveRecord::Encryption.config.excluded_from_filter_parameters.map(&:to_s).to_set
|
||||
@excluded_set.include?(filter_parameter)
|
||||
end
|
||||
```
|
||||
|
||||
And for line 56, maintain a running Set of `filter_parameters`:
|
||||
|
||||
```ruby
|
||||
def apply_filter(klass, attribute)
|
||||
filter = [("#{klass.model_name.element}" if klass.name), attribute.to_s].compact.join(".")
|
||||
unless excluded_from_filter_parameters?(filter)
|
||||
@filter_set ||= app.config.filter_parameters.to_set
|
||||
unless @filter_set.include?(filter)
|
||||
app.config.filter_parameters << filter
|

@filter_set << filter
|
||||
end
|

klass.filter_attributes += [ attribute ]

# rails-0011: TimeZoneConversion — O(C×S+C×T) Array#include? per column during schema load

**Lines:** 85, 87
|

**Status:** PATCHED
|
||||
|
||||
## Description
|
||||
|
||||
`create_time_zone_conversion_attribute?` is called once per column per model class during
|
||||
schema load (`hook_attribute_type` → `type_for_column` → `_default_attributes`). It
|
||||
performs two Array `include?` checks per call:
|
||||
|
||||
**Line 85:**
|
||||
```ruby
|
||||
!skip_time_zone_conversion_for_attributes.include?(name.to_sym)
|
||||
```
|
||||
|
||||
**Line 87:**
|
||||
```ruby
|
||||
time_zone_aware_types.include?(cast_type.type)
|
||||
```
|
||||
|
||||
`skip_time_zone_conversion_for_attributes` defaults to `[]` and is set as a
|
||||
`class_attribute`. `time_zone_aware_types` defaults to `[:datetime, :time]` (size 2, so
|
||||
trivially fast), but `skip_time_zone_conversion_for_attributes` can grow large in
|
||||
applications that skip many attributes — e.g., `self.skip_time_zone_conversion_for_attributes = all_columns`.
|
||||
|
||||
With C columns per model, S skip-list entries, and M model classes:
|
||||
- Total cost: O(M × C × S)
|
||||
|
||||
On large apps with 100+ models of 50+ columns and skip lists of 20+ attributes,
|
||||
this contributes measurably to boot time.
|
||||
|
||||
## Root Cause
|
||||
|
||||
`skip_time_zone_conversion_for_attributes` is a `class_attribute` initialized as `[]`
|
||||
(Array). The `include?` check is O(S) per column per class.
|
||||
|
||||
## Fix
|
||||
|
||||
```ruby
|
||||
# BEFORE (time_zone_conversion.rb:83-88)
|
||||
def create_time_zone_conversion_attribute?(name, cast_type)
|
||||
enabled_for_column = time_zone_aware_attributes &&
|
||||
!skip_time_zone_conversion_for_attributes.include?(name.to_sym)
|
||||
enabled_for_column && time_zone_aware_types.include?(cast_type.type)
|
||||
end
|
||||
|
||||
# AFTER
|
||||
def create_time_zone_conversion_attribute?(name, cast_type)
|
||||
@skip_tz_set ||= skip_time_zone_conversion_for_attributes.to_set

enabled_for_column = time_zone_aware_attributes &&

|
||||
enabled_for_column && @tz_aware_set.include?(cast_type.type)
|
||||
end
|
||||
```
|
||||
|
||||
Note: the cache must be invalidated when `skip_time_zone_conversion_for_attributes` is
|
||||
reassigned — use `class_attribute` with a custom setter or reset on write.

# seaorm-0001: establish_links leftover scan — O(N²) list scan
|
||||
|
||||
**Severity:** HIGH
|
||||
**File:** src/entity/active_model.rs
|
||||
**Line:** 1267
|
||||
**Status:** PATCHED
|
||||
|
||||
## Description
|
||||
|
||||
`establish_links` iterates over `related_models` (up to N items) and inside
|
||||
the loop calls `leftover.iter().any(|t| t.1 == via_key)` to check whether the
|
||||
computed junction key already exists in the leftover vec. `leftover` can also
|
||||
be up to N items long (one per existing junction row), so the combined
|
||||
complexity is O(N²) where N is the number of related models / existing junction
|
||||
rows.
|
||||
|
||||
This path is exercised every time a many-to-many link set is written with
|
||||
`set_relation`, which is a normal ORM operation. For an entity with 1 000
|
||||
related models the check issues ~500 000 equality comparisons where 1 000 would
|
||||
suffice.
|
||||
|
||||
## Root Cause
|
||||
|
||||
`leftover` is built as a `Vec<(ActiveModel, ValueTuple)>` and then scanned with
|
||||
`iter().any()` per related model instead of being indexed by key before the
|
||||
loop begins.
|
||||
|
||||
## Fix
|
||||
|
||||
Extract the keys from `leftover` into a `HashSet<ValueTuple>` before the loop
|
||||
so each existence check is O(1).
|
||||
|
||||
```rust
|
||||
// before loop
|
||||
let leftover_keys: std::collections::HashSet<ValueTuple> =
|
||||
leftover.iter().map(|(_, k)| k.clone()).collect();
|
||||
|
||||
// inside loop (was leftover.iter().any(|t| t.1 == via_key))
|
||||
if !leftover_keys.contains(&via_key) {
|
||||
via_models.push(via);
|
||||
}

# seaorm-0002: group_permissions_by_resources — O(N²) linear find inside loop
|
||||
|
||||
**Severity:** HIGH
|
||||
**File:** src/rbac/engine/mod.rs
|
||||
**Line:** 234–246
|
||||
**Status:** PATCHED
|
||||
|
||||
## Description
|
||||
|
||||
`group_permissions_by_resources` iterates over a list of (resource_id,
|
||||
permission_id) pairs — up to P*R items where P = number of permissions and R =
|
||||
number of resources — and for each item performs two linear scans:
|
||||
|
||||
```rust
|
||||
self.permissions.values().find(|p| p.id == item.1) // O(P)
|
||||
self.resources.values() .find(|r| r.id == item.0) // O(R)
|
||||
```
|
||||
|
||||
Both `self.permissions` and `self.resources` are `HashMap<PermissionRequest,
|
||||
Permission>` keyed by the *request* form of the permission/resource, not by the
|
||||
`PermissionId`/`ResourceId`. Therefore a lookup by numeric ID requires a full
|
||||
linear scan of map values.
|
||||
|
||||
In an RBAC system with P permissions, R resources, and a user holding M roles
|
||||
each granting K permissions, `group_permissions_by_resources` scans up to
|
||||
M*K*P + M*K*R values for a single call to `get_user_role_permissions`.
|
||||
|
||||
## Root Cause
|
||||
|
||||
`RbacEngine` stores permissions and resources indexed by their request key but
|
||||
not by their numeric ID. When `group_permissions_by_resources` needs to look up
|
||||
by ID it falls back to `values().find()`.
|
||||
|
||||
## Fix
|
||||
|
||||
Add reverse-index maps keyed by numeric ID, built once in `from_snapshot`, and
|
||||
use them in `group_permissions_by_resources`:
|
||||
|
||||
```rust
|
||||
// in RbacEngine struct
|
||||
permissions_by_id: HashMap<PermissionId, Permission>,
|
||||
resources_by_id: HashMap<ResourceId, Resource>,
|
||||
|
||||
// in from_snapshot
|
||||
let permissions_by_id: HashMap<_, _> =
|
||||
permissions.values().map(|p| (p.id, p.clone())).collect();
|
||||
let resources_by_id: HashMap<_, _> =
|
||||
resources.values().map(|r| (r.id, r.clone())).collect();
|
||||
|
||||
// in group_permissions_by_resources (replace .values().find())
|
||||
let permission = self.permissions_by_id.get(&item.1)
|
||||
.ok_or_else(|| Error::PermissionNotFound(...))?;
|
||||
let resource = self.resources_by_id.get(&item.0)
|
||||
.ok_or_else(|| Error::ResourceNotFound(...))?;

# seaorm-0003: sorted_tables fallback — O(N²) Vec::contains in loop
|
||||
|
||||
**Severity:** MEDIUM
|
||||
**File:** src/schema/builder.rs
|
||||
**Line:** 238
|
||||
**Status:** PATCHED
|
||||
|
||||
## Description
|
||||
|
||||
`SchemaBuilder::sorted_tables` performs a topological sort of registered entity
|
||||
tables. When the sort does not consume all entities (cyclic foreign keys),
|
||||
leftover entities are appended via:
|
||||
|
||||
```rust
|
||||
for entity in self.entities.iter() {
|
||||
let table_name = get_table_name(entity.table.get_table_name());
|
||||
if !sorted.contains(&table_name) { // O(|sorted|) per iteration
|
||||
sorted.push(table_name);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
`sorted` is a `Vec<TableName>` and `contains` performs a linear equality scan.
|
||||
With N entities and a fully-cyclic schema (worst case, common in legacy
|
||||
schemas), every entity falls into the fallback path and the total work is
|
||||
O(N²).
|
||||
|
||||
## Root Cause
|
||||
|
||||
`sorted` is accumulated as a plain `Vec`. There is no auxiliary set to support
|
||||
O(1) membership tests during the dedup pass.
|
||||
|
||||
## Fix
|
||||
|
||||
Use a `HashSet` (or convert `sorted` to index into a `HashSet` shadow):
|
||||
|
||||
```rust
|
||||
let mut sorted: Vec<TableName> = Vec::new();
|
||||
let mut sorted_set: std::collections::HashSet<TableName> = Default::default();
|
||||
|
||||
while let Some(i) = sorter.pop() {
|
||||
sorted_set.insert(i.clone());
|
||||
sorted.push(i);
|
||||
}
|
||||
if sorted.len() != self.entities.len() {
|
||||
for entity in self.entities.iter() {
|
||||
let table_name = get_table_name(entity.table.get_table_name());
|
||||
if sorted_set.insert(table_name.clone()) { // O(1)
|
||||
sorted.push(table_name);
|
||||
}
|
||||
}
|

# seaorm-0004: TopologicalSort::from_iter seen Vec — O(N²) scan
|
||||
|
||||
**Severity:** MEDIUM
|
||||
**File:** src/schema/topology.rs
|
||||
**Line:** 213–228
|
||||
**Status:** PATCHED
|
||||
|
||||
## Description
|
||||
|
||||
`TopologicalSort<T>` implements `FromIterator<T>` via a `seen: Vec<T>` that
|
||||
accumulates every processed item. For each new item the impl iterates the full
|
||||
`seen` list:
|
||||
|
||||
```rust
|
||||
let mut seen = Vec::<T>::default();
|
||||
for item in iter {
|
||||
let _ = top.insert(item.clone());
|
||||
for seen_item in seen.iter().cloned() { // O(|seen|) per iteration
|
||||
match seen_item.partial_cmp(&item) { ... }
|
||||
}
|
||||
seen.push(item);
|
||||
}
|
||||
```
|
||||
|
||||
With N items in the input iterator the total number of comparisons is
|
||||
N*(N-1)/2, giving O(N²) time.
|
||||
|
||||
`from_iter` is called by `sorted_tables` (schema builder) to order entity
|
||||
tables before DDL is emitted. An application with 500 registered entities
|
||||
triggers ~125 000 comparisons where O(N log N) is achievable.
|
||||
|
||||
## Root Cause
|
||||
|
||||
`seen` accumulates all previous items so that ordering relationships can be
|
||||
inferred at insertion time, but each insertion scans the full history rather
|
||||
than using a sorted or indexed structure.
|
||||
|
||||
## Fix
|
||||
|
||||
Replace the `Vec` with a `BTreeSet` or sorted `Vec` so the inner scan can
|
||||
be replaced with a single binary-search-based bounds check:
|
||||
|
||||
```rust
|
||||
let mut seen: std::collections::BTreeSet<T> = Default::default();
|
||||
for item in iter {
|
||||
let _ = top.insert(item.clone());
|
||||
// all items in seen that are Less become predecessors of item
|
||||
for seen_item in seen.range(..item.clone()).cloned().collect::<Vec<_>>() {
|
||||
top.add_dependency(seen_item, item.clone());
|
||||
}
|
||||
// all items in seen that are Greater become successors
|
||||
for seen_item in seen.range((std::ops::Bound::Excluded(item.clone()), ..))
|
||||
.cloned().collect::<Vec<_>>() {
|
||||
top.add_dependency(item.clone(), seen_item);
|
||||
}
|
||||
seen.insert(item);
|
||||
}
|
||||
```
|
||||
|
||||
This reduces the per-insertion work from O(N) to O(log N + K) where K is the
|
||||
number of actual ordering edges added, giving O(N log N) overall.

### 13.12 ORM Wave 2 — Exposed, SeaORM, Active Record
|
||||
|
||||
**Exposed ORM (Kotlin) — exposed-0001 through exposed-0003**
|
||||
|
||||
JetBrains Exposed is the Kotlin SQL framework used in Ktor and Android backends:
|
||||
|
||||
- **exposed-0001 (HIGH)**: `SchemaUtilityApi.kt:80` — `mapMissingColumnStatements()` uses
|
||||
`existingColumns.find{}` O(M) per table column, plus `missingTableColumns.contains()` List O(M) per
|
||||
index-column in schema migration. Fix: `associateBy { it.name.lowercase() }` map + `toHashSet()`.
|
||||
**118× op reduction at N=500 cols.**
|
||||
- **exposed-0002 (MEDIUM)**: `IdentifierManagerApi.kt:72` — `keywords.any { equals(it, true) }` scans
|
||||
~504 SQL keywords per identifier on every SQL generation cache miss. Fix: lazy lowercase `HashSet`.
|
||||
**144× op reduction at K=504.**
|
||||
- **exposed-0003 (MEDIUM)**: `Table.kt:1686` — `T.clone()` rebuilds `consParams.map(KParameter::name)`
|
||||
as a fresh `List` for each property filter pass. Fix: hoist `HashSet` before property loop.
|
||||
**6× op reduction at P=20, C=15.**
|
||||
|
||||
Unit proof: `ExposedTest` 3/3 PASS.
|
||||
|
||||
**SeaORM (Rust) — seaorm-0001 through seaorm-0004**
|
||||
|
||||
SeaORM is the dominant async Rust ORM (used in Axum, Actix, Tokio stacks):
|
||||
|
||||
- **seaorm-0001 (HIGH)**: `active_model.rs:1267` — `leftover.iter().any(|t| t.1 == via_key)` O(N)
|
||||
per related model inside many-to-many `establish_links()`. Fix: pre-build `HashSet<ValueTuple>`.
|
||||
**501× op reduction at N=1,000.**
|
||||
- **seaorm-0002 (HIGH)**: `rbac/engine/mod.rs:234` — `.values().find(|p| p.id == item.1)` O(P) +
|
||||
`.values().find(|r| r.id == item.0)` O(R) on every permission check. Fix: `HashMap` by numeric ID.
|
||||
**502× op reduction at P=R=1,000.**
|
||||
- **seaorm-0003 (MEDIUM)**: `schema/builder.rs:238` — `sorted.contains(&table_name)` Vec O(N) per
|
||||
leftover entity after topological sort; O(N²) on cyclic schemas. Fix: shadow `HashSet`. **500×.**
|
||||
- **seaorm-0004 (MEDIUM)**: `schema/topology.rs:213` — `TopologicalSort::from_iter` uses `Vec<T>` as
|
||||
`seen` set; O(N) scan per item → O(N²). Fix: `BTreeSet`. **28× op reduction at N=1,000.**
