Major test suite improvements and API enhancements

Test Coverage Improvements:
- Increased API test coverage from 43.2% to 46.3%
- Added comprehensive tests for database operations, metrics, and middleware
- Enhanced existing test suites with additional edge cases and error scenarios
- Removed redundant cmd/*_test.go files (already covered by system tests)

API Enhancements:
- Added metadata update capability to PUT /api/publish endpoint
- Now supports updating Origin, Label, Suite, Codename, NotAutomatic, and ButAutomaticUpgrades fields
- Metadata changes are applied during the publish operation

Infrastructure Updates:
- Fixed etcd batch write panic with proper retry logic
- Enhanced S3 upload with better concurrent operation handling
- Improved task management with better error handling and race condition prevention
- Updated etcd install script to support both x86_64 and arm64 architectures

Code Quality:
- Fixed go vet issues and code formatting problems
- Enhanced error messages and logging throughout the codebase
- Improved resource cleanup in test suites
- Better handling of nil values and edge cases

Build System:
- Updated Makefile with improved dependency management
- Enhanced .golangci.yml configuration for better linting
- Added VERSION file management
- Updated .gitignore for better coverage tracking

Documentation:
- Integrated macOS testing guide into CONTRIBUTING.md
- Added platform-specific setup instructions
- Improved test running documentation with multiple options

+
+### Local Development Setup
+
+This section describes local setup to start contributing to aptly.
+
+#### Dependencies
+
+Building aptly requires go version 1.24.
+
+On Debian bookworm with backports enabled, go can be installed with:
+
+    apt install -t bookworm-backports golang-go
+
+#### Building
+
+To build aptly, run:
+
+    make build
+
+Run aptly:
+
+    build/aptly
+
+To install aptly into `$GOPATH/bin`, run:
+
+    make install
+
+#### Platform-Specific Setup
+
+##### macOS
+
+This guide explains how to run aptly tests on macOS, including Apple Silicon (M1/M2) machines.
+
+###### Prerequisites
+
+1. **Install Go** (1.24 or later):
+   ```bash
+   brew install go
+   ```
+
+2. **Install Docker** (for etcd and other services):
+   ```bash
+   brew install --cask docker
+   ```
+
+3. **Install test dependencies**:
+   ```bash
+   # Add Go binaries to PATH
+   export PATH=$PATH:~/go/bin
+   
+   # Install swag for API documentation
+   go install github.com/swaggo/swag/cmd/swag@latest
+   
+   # Install other tools
+   brew install etcd  # Optional: for local etcd instead of Docker
+   ```
+
+###### Running Tests on macOS
+
+**Option 1: Using Docker Compose (Recommended)**
+
+```bash
+# Start test services
+docker-compose -f docker-compose.ci.yml up -d etcd
+
+# Run tests
+PATH=$PATH:~/go/bin make test
+```
+
+**Option 2: Using Local etcd**
+
+```bash
+# Install and start etcd locally
+brew services start etcd
+
+# Run tests with local etcd
+ETCD_ENDPOINTS=localhost:2379 go test ./...
+```
+
+**Option 3: Run Specific Test Suites**
+
+```bash
+# Fix VERSION file if needed
+echo "1.5.0" > VERSION
+
+# Run unit tests only
+PATH=$PATH:~/go/bin make test-unit GOTEST="go test -short -timeout=5m"
+
+# Run specific packages
+go test ./deb ./s3 ./utils ./context -short -v
+
+# Run with race detection
+go test -race ./deb ./s3 ./utils -short
+```
+
+###### macOS-Specific Considerations
+
+1. **CPU Architecture**: The install scripts now support both Intel (x86_64) and Apple Silicon (arm64).
+
+2. **File System**: macOS is case-insensitive by default, which may affect some tests.
+
+3. **Network**: Some tests may require adjusting firewall settings.
+
+4. **Timeouts**: Some tests may need longer timeouts on macOS:
+   ```bash
+   go test -timeout=10m ./...
+   ```
+
+###### Troubleshooting on macOS
+
+**etcd Installation Fails**
+
+If the automatic etcd installation fails, use Docker or Homebrew:
+```bash
+# Using Docker
+docker run -d -p 2379:2379 --name etcd quay.io/coreos/etcd:latest
+
+# Using Homebrew
+brew install etcd
+etcd --listen-client-urls http://0.0.0.0:2379 --advertise-client-urls http://localhost:2379
+```
+
+**Test Timeouts**
+
+Increase timeouts for slower tests:
+```bash
+go test -timeout=30m ./...
+```
+
+**Race Detector Issues**
+
+The race detector may be slower on macOS. Disable for faster runs:
+```bash
+go test ./... -short
+```
+
+###### CI Integration for macOS
+
+For GitHub Actions on macOS:
+
+```yaml
+jobs:
+  test-macos:
+    runs-on: macos-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-go@v5
+        with:
+          go-version: '1.24'
+      
+      - name: Install dependencies
+        run: |
+          brew install etcd
+          go install github.com/swaggo/swag/cmd/swag@latest
+      
+      - name: Run tests
+        run: |
+          export PATH=$PATH:~/go/bin
+          make test
+```
+
+###### Test Coverage on macOS
+
+Generate coverage reports:
+```bash
+go test -coverprofile=coverage.out ./...
+go tool cover -html=coverage.out -o coverage.html
+open coverage.html
+```
+
+#### Unit-tests
+
+aptly has two kinds of tests: unit-tests and functional (system) tests. Functional tests are preferred way to test any
+feature, but some features are much easier to test with unit-tests (e.g. algorithms, failure scenarios, ...)
+
+aptly is using standard Go unit-test infrastructure plus [gocheck](http://labix.org/gocheck). Run the unit-tests with:
+
+    make test
+
+#### Functional Tests
+
+Functional tests are implemented in Python, and they use custom test runner which is similar to Python unit-test
+runner. Most of the tests start with clean aptly state, run some aptly commands to prepare environment, and finally
+run some aptly commands capturing output, exit code, checking any additional files being created and so on. API tests
+are a bit different, as they re-use same aptly process serving API requests.
+
+The easiest way to run functional tests is to use `make`:
+
+    make system-test
+
+This would check all the dependencies and run all the tests. Some tests (S3, Swift) require access credentials to
+be set up in the environment. For example, it needs AWS credentials to run S3 tests (they would be used to publish to S3).
+If credentials are missing, tests would be skipped.
+
+You can also run subset of tests manually:
+
+    system/run.py t04_mirror
+
+This would run all the mirroring tests under `system/t04_mirror` folder.
+
+Or you can run tests by test name mask:
+
+    system/run.py UpdateMirror*
+
+Or, you can run specific test by name:
+
+    system/run.py UpdateMirror7Test
+
+Test runner can update expected output instead of failing on mismatch (this is especially useful while
+working on new tests):
+
+    system/run.py --capture <test>
+
+Output for some tests might contain environment-specific things, e.g. your home directory. In that case
+you can use `${HOME}` and similar variable expansion in expected output files.
+
+Some tests depend on fixtures, for example pre-populated GPG trusted keys. There are also test fixtures
+captured after mirror update which contain pre-build aptly database and pool contents. They're useful if you
+don't want to waste time in the test on populating aptly database while you need some packages to work with.
+There are some packages available under `system/files/` directory which are used to build contents of local repos.
+
+*WARNING*: tests are running under current `$HOME` directory with aptly default settings, so they clear completely
+`~/.aptly.conf` and `~/.aptly` subdirectory between the runs. So it's not wise to have non-dev aptly being used with
+this default location. You can run aptly under different user or by using non-default config location with non-default
+aptly root directory.
+
+### Continuous Integration (CI)
+
+aptly uses GitHub Actions for continuous integration. The CI pipeline includes:
+
+- **Quick checks**: Code formatting, go vet, mod tidy, and flake8 linting
+- **Security scanning**: govulncheck and Trivy vulnerability scanning  
+- **Linting**: golangci-lint with extensive checks
+- **Unit tests**: With race detection on Go 1.23 and 1.24
+- **Integration tests**: Full system tests with cloud storage backends
+- **Benchmarks**: Performance testing
+- **Extended tests**: Combined unit tests and benchmarks with coverage merging
+- **Cross-platform builds**: Binaries for Linux, macOS, Windows, FreeBSD (multiple architectures)
+- **Debian packages**: Built for Debian (buster, bullseye, bookworm, trixie) and Ubuntu (focal, jammy, noble)
+- **Docker images**: Multi-architecture container images (linux/amd64, linux/arm64)
+
+All pull requests must pass CI checks before merging. Build artifacts are available for download from GitHub Actions runs with the following retention:
+- CI builds: 7 days
+- Tagged releases: 90 days
+
+#### Testing CI Locally with act
+
+You can test GitHub Actions workflows locally using [act](https://github.com/nektos/act):
+
+```bash
+# Install act
+brew install act              # macOS
+# or
+curl https://raw.githubusercontent.com/nektos/act/master/install.sh | sudo bash  # Linux
+
+# Run default push event
+act
+
+# Run pull request event
+act pull_request
+
+# Run specific job
+act -j test-unit
+
+# Run with specific matrix values
+act -j test-unit --matrix go:1.24
+
+# List all available jobs
+act -l
+```
+
+For Apple Silicon Macs, use: `act --container-architecture linux/amd64`
+
+Common use cases:
+- Test a job before pushing: `act -j quick-checks`
+- Test PR workflows: Create a PR event file and run `act pull_request -e pr-event.json`
+- Debug failures: `act -j failing-job -v` for verbose output
+- Use secrets: Create `.secrets` file with `KEY=value` format and run `act --secret-file .secrets`
+
+### man Page
+
+aptly is using combination of [Go templates](http://godoc.org/text/template) and automatically generated text to build `aptly.1` man page. If either source
+template [man/aptly.1.ronn.tmpl](man/aptly.1.ronn.tmpl) is changed or any command help is changed, run `make man` to regenerate
+final rendered man page [man/aptly.1](man/aptly.1). In the end of the build, new man page is displayed for visual
+verification.
+
+Man page is built with small helper [\_man/gen.go](man/gen.go) which pulls in template, command-line help from [cmd/](cmd/) folder
+and runs that through [forked copy](https://github.com/smira/ronn) of [ronn](https://github.com/rtomayko/ronn).
+
+### Bash and Zsh Completion
+
+Bash and Zsh completion for aptly reside in the same repo under in [completion.d/aptly](completion.d/aptly) and
+[completion.d/\_aptly](completion.d/_aptly), respectively. It's all hand-crafted.
+When new option or command is introduced, bash completion should be updated to reflect that change.
+
+When aptly package is being built, it automatically pulls bash completion and man page into the package.

+Installation
+=============
 
-Download
---------
+Aptly can be installed on several operating systems.
 
-To install aptly on Debian/Ubuntu, add new repository to /etc/apt/sources.list::
+Debian / Ubuntu
+----------------
 
-    deb http://repo.aptly.info/ squeeze main
+Aptly is provided in the following debian packages:
 
-And import key that is used to sign the release::
+* **aptly**: Includes the main Aptly binary, man pages, and shell completions
+* **aptly-api**: A systemd service for the REST API, using the global /etc/aptly.conf
+* **aptly-dbg**: Debug symbols for troubleshooting
 
-    $ gpg --keyserver keys.gnupg.net --recv-keys 2A194991
-    $ gpg -a --export 2A194991 | sudo apt-key add -
+The packages can be installed on official `Debian <https://packages.debian.org/search?keywords=aptly>`_ and `Ubuntu <https://packages.ubuntu.com/search?keywords=aptly>`_ distributions.
 
-After that you can install aptly as any other software package::
+Upstream Debian Packages
+~~~~~~~~~~~~~~~~~~~~~~~~~
 
-    $ apt-get update
-    $ apt-get install aptly
+If a newer version (not available in Debian/Ubuntu) of aptly is required, upstream debian packages (built from git tags) can be installed as follows:
 
-Don't worry about squeeze part in repo name: aptly package should work on Debian squeeze+,
-Ubuntu 10.0+. Package contains aptly binary, man page and bash completion.
+Install the following APT key (as root)::
 
-Binary executables (depends almost only on libc) are available for download from `Bintray <http://dl.bintray.com/smira/aptly/>`_.
+    wget -O /etc/apt/keyrings/aptly.asc https://www.aptly.info/pubkey.txt
 
-If you have Go environment set up, you can build aptly from source by running (go 1.2+ required)::
+Define Release APT sources in ``/etc/apt/sources.list.d/aptly.list``::
 
-    go get -u github.com/mattn/gom
-    mkdir -p $GOPATH/src/github.com/smira/aptly
-    git clone https://github.com/smira/aptly $GOPATH/src/github.com/smira/aptly
-    cd $GOPATH/src/github.com/smira/aptly
-    gom -production install
-    gom build -o $GOPATH/bin/aptly
+    deb [signed-by=/etc/apt/keyrings/aptly.asc] http://repo.aptly.info/release DIST main
 
-Aptly is using `gom <https://github.com/mattn/gom>`_ to fix external dependencies, so regular ``go get github.com/smira/aptly``
-should work as well, but might fail or produce different result (if external libraries got updated).
+Where DIST is one of: ``buster``, ``bullseye``, ``bookworm``, ``focal``, ``jammy``, ``noble``
 
-If you don't have Go installed (or older version), you can easily install Go using `gvm <https://github.com/moovweb/gvm/>`_.
+Install aptly packages::
 
+    apt-get update
+    apt-get install aptly
+    apt-get install aptly-api  # REST API systemd service
 
+CI Builds
+~~~~~~~~~~
+
+For testing new features or bugfixes, recent builds are available as CI builds (built from master, may be unstable!) and can be installed as follows:
+
+Define CI APT sources in ``/etc/apt/sources.list.d/aptly-ci.list``::
+
+    deb [signed-by=/etc/apt/keyrings/aptly.asc] http://repo.aptly.info/ci DIST main
+

+
+Configuration
+=============
+
+etcd Database Configuration
+---------------------------
+
+When using etcd as the database backend, aptly supports several environment variables for configuration:
+
+**Timeout Configuration:**
+
+- ``APTLY_ETCD_TIMEOUT``: Operation timeout for etcd requests (default: ``60s``)
+  
+  Example: ``export APTLY_ETCD_TIMEOUT=30s``
+
+- ``APTLY_ETCD_DIAL_TIMEOUT``: Connection timeout when establishing etcd connection (default: ``60s``)
+  
+  Example: ``export APTLY_ETCD_DIAL_TIMEOUT=10s``
+
+**Connection Configuration:**
+
+- ``APTLY_ETCD_KEEPALIVE``: Keep-alive timeout for etcd connections (default: ``7200s``)
+  
+  Example: ``export APTLY_ETCD_KEEPALIVE=3600s``
+
+- ``APTLY_ETCD_MAX_MSG_SIZE``: Maximum message size in bytes for etcd requests/responses (default: ``52428800`` - 50MB)
+  
+  Example: ``export APTLY_ETCD_MAX_MSG_SIZE=104857600``  # 100MB
+
+**Example Configuration:**
+
+.. code-block:: bash
+
+    # Set shorter timeouts for faster failure detection
+    export APTLY_ETCD_TIMEOUT=30s
+    export APTLY_ETCD_DIAL_TIMEOUT=10s
+    
+    # Increase message size for large package operations
+    export APTLY_ETCD_MAX_MSG_SIZE=104857600
+    
+    # Run aptly with etcd backend
+    aptly -config=/etc/aptly-etcd.conf mirror update debian-stable
+
+**Features:**
+
+- **Automatic Retry**: Read operations (Get) automatically retry up to 3 times with exponential backoff on temporary failures
+- **Timeout Protection**: All etcd operations use context with timeout to prevent indefinite hangs
+- **Enhanced Logging**: All etcd errors are logged with operation context for better debugging
+- **Configurable Limits**: Message size limits can be adjusted for large package operations
+
+etcd Write Queue Configuration
+------------------------------
+
+To prevent etcd overload during concurrent operations (e.g., multiple mirror updates), aptly supports an optional write queue that serializes database write operations:
+
+**Configuration in aptly.conf:**
+
+.. code-block:: json
+
+    {
+      "databaseBackend": {
+        "type": "etcd",
+        "url": "localhost:2379",
+        "timeout": "120s",
+        "writeRetries": 3,
+        "writeQueue": {
+          "enabled": true,
+          "queueSize": 1000,
+          "maxWritesPerSec": 100,
+          "batchMaxSize": 50,
+          "batchMaxWaitMs": 10
+        }
+      }
+    }
+
+**Write Queue Options:**
+
+- ``enabled``: Enable/disable the write queue (default: ``false``)
+- ``queueSize``: Size of the write operation queue (default: ``1000``)
+- ``maxWritesPerSec``: Maximum write operations per second (default: ``100``)
+- ``batchMaxSize``: Maximum batch size for future batching support (default: ``50``)
+- ``batchMaxWaitMs``: Maximum wait time for batch accumulation in milliseconds (default: ``10``)
+
+**Benefits:**
+
+- **Prevents etcd Overload**: Serializes write operations to avoid overwhelming etcd
+- **Maintains Parallelism**: I/O operations like downloads remain parallel
+- **Rate Limiting**: Configurable writes per second to match etcd capacity
+- **Transparent**: No code changes required, just enable in configuration
+
+**Example Impact:**
+
+Without write queue: 5 mirror updates → 5 parallel writers → 1000s of concurrent etcd operations → timeouts
+
+With write queue: 5 mirror updates → 5 parallel processes → 1 sequential etcd writer → stable performance
