Dream Hunter 7c6d0d7c8a feat(mail): support gzip compressed email storage via ENABLE_MAIL_GZIP (#933)
* feat(mail): support gzip compressed email storage in D1 raw_blob column

Add ENABLE_MAIL_GZIP env var to optionally gzip-compress incoming emails
into a new raw_blob BLOB column, saving D1 storage space. Reading is
backward-compatible: prioritizes raw_blob (decompress) with fallback to
plaintext raw field. Includes DB migration v0.0.7, docs, and changelogs.

* fix: gzip fallback on missing column + decouple resolve from handleListQuery

- email/index.ts: gzip INSERT failure now falls back to plaintext INSERT
  instead of silently losing the email (P1: data loss prevention)
- common.ts: add handleMailListQuery for raw_mails-specific list queries
  with resolveRawEmailList, keeping handleListQuery generic
- Replace handleListQuery → handleMailListQuery in mails_api, admin_mail_api,
  user_mail_api (only raw_mails callers)
- Add e2e test infrastructure: worker-gzip service, wrangler.toml.e2e.gzip,
  api-gzip playwright project, mail-gzip.spec.ts with 4 test cases

* fix: address CodeRabbit review feedback for gzip feature

- Use destructuring in resolveRawEmailRow to truly remove raw_blob key
- Narrow fallback scope: only fallback to plaintext on compression failure
  or missing raw_blob column, re-throw other DB errors
- Clean unused imports in e2e gzip test

* fix: add try-catch in resolveRawEmail to prevent single corrupt blob from failing entire list

A corrupted raw_blob would cause decompressBlob to throw, which with
Promise.all in resolveRawEmailList would reject the entire batch query.
Now catches decompression errors and falls back to row.raw field.

* fix(mail): align sendAdminInternalMail with gzip storage path

sendAdminInternalMail now respects ENABLE_MAIL_GZIP: compresses to
raw_blob when enabled, with fallback to plaintext on failure.
Added e2e test verifying admin internal mail is readable under gzip.

* fix(e2e): match admin internal mail by body content instead of encoded subject

mimetext base64-encodes the Subject header, so the raw MIME string
does not contain the literal subject text. Match on body content
(balance: 99) which is plaintext.

* fix(e2e): add WORKER_GZIP_URL guard and length assertions in gzip tests

Address CodeRabbit feedback:
- Skip gzip tests when WORKER_GZIP_URL is not set to prevent false positives
- Assert results array length before accessing [0] for clearer error messages

* fix(mail): narrow gzip fallback scope and fix webhook query compatibility

- sendAdminInternalMail: separate compress vs DB error handling, only
  fallback to plaintext on compression failure or missing raw_blob
  column, rethrow other DB errors (aligns with email/index.ts)
- Webhook test endpoints: use SELECT * instead of explicit raw_blob
  column reference, so pre-migration databases don't 500
- Docs/changelog: clarify that db_migration must run before enabling
  ENABLE_MAIL_GZIP

* fix(telegram): use generic Record type for raw_mails query result

Align with other query sites — avoid hardcoding raw_blob in the
TypeScript type annotation so the query works with or without the
column after migration.

* refactor(models): add RawMailRow type and unify raw_mails query typing

Add RawMailRow type to models with raw_blob as optional field, replacing
ad-hoc Record<string, unknown> and inline type annotations across
webhook test endpoints, telegram API, and gzip utilities.

E2E Tests

End-to-end tests for Cloudflare Temp Email using Playwright and Mailpit, fully containerized with Docker Compose.

Prerequisites

  • Docker and Docker Compose

Quick Start

cd e2e

# Build, start all services, run tests, and exit
npm test

# Clean up containers and volumes
npm run test:down

npm test runs docker compose up --build, which:

  1. Starts Mailpit (SMTP on :1025, HTTP API on :8025)
  2. Builds and starts the Worker (wrangler dev on :8787)
  3. Builds and starts the Frontend (vite dev on :5173)
  4. Builds and runs the E2E runner (Playwright), which waits for services, initializes the DB, and runs all tests

The exit code reflects the test result.

Test Structure

Project Directory What it tests
api tests/api/ Worker API endpoints — health check, address CRUD, send mail via SMTP
browser tests/browser/ Frontend UI — login, inbox view, reply with HTML, XSS sanitization

Services

Service Container Port Purpose
Mailpit SMTP mailpit 1025 Captures outgoing emails
Mailpit HTTP mailpit 8025 API to verify captured emails
Worker worker 8787 Backend API with E2E config
Frontend frontend 5173 Vue frontend dev server

Test Results

Test results and HTML reports are exported via volumes:

  • e2e/test-results/ — test artifacts
  • e2e/playwright-report/ — HTML report

Configuration

The E2E worker uses fixtures/wrangler.toml.e2e with:

  • E2E_TEST_MODE = true — enables test seed endpoint
  • DISABLE_ADMIN_PASSWORD_CHECK = true — allows unauthenticated admin calls
  • DEFAULT_SEND_BALANCE = 10 — allows sending without admin approval
  • SMTP pointed at Mailpit container (mailpit:1025)
