From 4368e5ca07ab9c5764250f88bd22d666970f503c Mon Sep 17 00:00:00 2001 From: ReinaMaze Date: Wed, 25 Feb 2026 17:49:50 +0100 Subject: [PATCH] feat: Add comprehensive tests for unique sequential project IDs - Add 8 new tests verifying sequential ID assignment starting from 1 - Test multiple users registering projects get unique IDs - Test rapid registration scenarios with no duplicate IDs - Test project retrieval returns correct IDs - Test events contain correct project IDs - Test ID preservation during updates - Test IDs are sequential across different categories - Add implementation and flow documentation All acceptance criteria met: - IDs increment sequentially starting from 1 - No duplicate IDs allowed - Project retrieval functions return correct ID - Tests ensure sequential assignment with multiple users --- PROJECT_ID_FLOW.md | 111 +++++++++++ PROJECT_ID_IMPLEMENTATION.md | 126 +++++++++++++ src/project_registry.rs | 353 +++++++++++++++++++++++++++++++++++ 3 files changed, 590 insertions(+) create mode 100644 PROJECT_ID_FLOW.md create mode 100644 PROJECT_ID_IMPLEMENTATION.md diff --git a/PROJECT_ID_FLOW.md b/PROJECT_ID_FLOW.md new file mode 100644 index 0000000..df13f93 --- /dev/null +++ b/PROJECT_ID_FLOW.md @@ -0,0 +1,111 @@ +# Project ID Assignment Flow + +## Sequential ID Counter System + +``` +┌─────────────────────────────────────────────────────────────┐ +│ Project Registration Flow │ +└─────────────────────────────────────────────────────────────┘ + +User A registers "Project Alpha" + │ + ├─> next_project_id() → Returns 1 (default) + ├─> Create Project { id: 1, ... } + ├─> Store Project(1) → Project data + ├─> set_next_project_id(1) → Stores 2 + └─> Emit ProjectRegistered { project_id: 1, ... } + +User B registers "Project Beta" + │ + ├─> next_project_id() → Returns 2 + ├─> Create Project { id: 2, ... } + ├─> Store Project(2) → Project data + ├─> set_next_project_id(2) → Stores 3 + └─> Emit ProjectRegistered { project_id: 2, ... } + +User A registers "Project Gamma" + │ + ├─> next_project_id() → Returns 3 + ├─> Create Project { id: 3, ... } + ├─> Store Project(3) → Project data + ├─> set_next_project_id(3) → Stores 4 + └─> Emit ProjectRegistered { project_id: 3, ... } +``` + +## Storage Structure + +``` +Persistent Storage: +┌──────────────────────────────────────────────────────────┐ +│ Key: NextProjectId │ Value: 4 │ +├──────────────────────────────────────────────────────────┤ +│ Key: Project(1) │ Value: Project { id: 1 } │ +├──────────────────────────────────────────────────────────┤ +│ Key: Project(2) │ Value: Project { id: 2 } │ +├──────────────────────────────────────────────────────────┤ +│ Key: Project(3) │ Value: Project { id: 3 } │ +└──────────────────────────────────────────────────────────┘ +``` + +## Key Functions + +### `next_project_id(env: &Env) -> u64` +```rust +// Retrieves the next available ID +// Returns 1 if no projects exist yet +env.storage() + .persistent() + .get(&DataKey::NextProjectId) + .unwrap_or(1) +``` + +### `set_next_project_id(env: &Env, id: u64)` +```rust +// Increments the counter for next registration +// Stores (current_id + 1) +env.storage() + .persistent() + .set(&DataKey::NextProjectId, &(id + 1)) +``` + +## Guarantees + +1. **Uniqueness**: Each ID is used exactly once +2. **Sequential**: IDs increment by 1 (1, 2, 3, 4, ...) +3. **Persistent**: Counter survives contract restarts +4. **Atomic**: No race conditions in Soroban's execution model +5. **Immutable**: Project IDs never change after creation + +## Usage Across Contract + +### Project Registry +- `register_project()` -
