maven.rs

//! Parser for Apache Maven pom.xml files.
//!
//! Extracts package metadata, dependencies, and license information from
//! Maven Project Object Model (POM) files.
//!
//! # Supported Formats
//! - pom.xml (Project Object Model)
//! - pom.properties
//! - MANIFEST.MF (JAR manifest)
//!
//! # Key Features
//! - Property value substitution (`${project.version}`)
//! - `is_pinned` analysis (exact version vs ranges like `[1.0,2.0)`)
//! - Dependency scope handling (compile, test, provided, runtime, system)
//! - Package URL (purl) generation
//! - Multiple license support (combined with " OR ")
//!
//! # Implementation Notes
//! - Uses quick-xml for XML parsing
//! - Version pinning: `"1.0.0"` is pinned, `"[1.0,2.0)"` is not
//! - Property substitution limited to prevent infinite loops
//! - Direct dependencies: all in pom.xml are direct

/// Resolves Maven property placeholders (`${property.name}`) with cycle and DoS protection.
///
/// Maven properties can reference other properties, creating dependency graphs. This resolver:
/// - Resolves nested placeholders: `${outer.${inner}}`
/// - Detects circular references: `${a}` → `${b}` → `${a}`
/// - Enforces depth limits to prevent stack overflow
/// - Enforces substitution limits to prevent DoS on pathological inputs
///
/// # Algorithm
///
/// Uses byte-level parsing for efficient placeholder extraction. Tracks:
/// - `resolving_set`: For cycle detection (hash set lookup)
/// - `resolving_stack`: For error reporting (preserves path)
/// - `cache`: Memoizes resolved values to avoid redundant work
