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

 ## Development Setup
 
-This section describes local setup to start contributing to aptly source.
+Working on aptly code can be done locally on the development machine, or for convenience by using docker. The next sections describe the setup process.
 
-### Go & Python
+### Docker Development Setup
 
-You would need `Go` (latest version is recommended) and `Python` 2.7.x (3.x is not supported yet).
+This section describes the docker setup to start contributing to aptly.
 
-If you're new to Go, follow [getting started guide](https://golang.org/doc/install) to install it and perform
-initial setup. With Go 1.8+, default `$GOPATH` is `$HOME/go`, so rest of this document assumes that.
+#### Dependencies
 
-Usually `$GOPATH/bin` is appended to your `$PATH` to make it easier to run built binaries, but you might choose
-to prepend it or to skip this test if you're security conscious.  
+Install the following on your development machine:
+- docker
+- make
+- git
 
-### Forking and Cloning
+##### Docker installation on macOS
+1. Install [Docker Desktop on Mac](https://docs.docker.com/desktop/setup/install/mac-install/) (or via [Homebrew](https://brew.sh/))
+2. Allow directory sharing
+   - Open Docker Desktop
+   - Go to `Settings → Resources → File Sharing → Virtual File Shares`
+   - Add the aptly git repository path to the shared list (eg. /home/Users/john/aptly)
 
-As Go is using repository path in import paths, it's better to clone aptly repo (not your fork) at default location:
+#### Create docker container
 
-    mkdir -p ~/go/src/github.com/smira
-    cd ~/go/src/github.com/smira
-    git clone git@github.com:smira/aptly.git
-    cd aptly
+To build the development docker image, run:
+```
+make docker-image
+```
 
-For main repo under your GitHub user and add it as another Git remote:
+#### Build aptly
 
-    git remote add <user> git@github.com:<user>/aptly.git
+To build the aptly in the development docker container, run:
+```
+make docker-build
+```
 
-That way you can continue to build project as is (you don't need to adjust import paths), but you would need
-to specify your remote name when pushing branches:
+#### Running aptly commands
 
-    git push <user> <your-branch>
+To run aptly commands in the development docker container, run:
+```
+make docker-shell
+```
 
-### Dependencies
+Example:
+```
+$ make docker-shell
+aptly@b43e8473ef81:/work/src$ aptly version
+aptly version: 1.5.0+189+g0fc90dff
+```
 
-You would need some additional tools and Python virtual environment to run tests and checks, install them with:
+#### Running unit tests
 
-    make prepare dev system/env
+In order to run aptly unit tests, enter the following:
+```
+make docker-unit-tests
+```
 
-This is usually one-time action.
+#### Running system tests
 
-### Building
+In order to run aptly system tests, enter the following:
+```
+make docker-system-tests
+```
 
-If you want to build aptly binary from your current source tree, run:
+#### Running golangci-lint
+
+In order to run aptly unit tests, run:
+```
+make docker-lint
+```
+
+#### More info
+
+Run `make help` for more information.
+
+
+### 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
 
-This would build `aptly` in `$GOPATH/bin`, so depending on your `$PATH`, you should be able to run it immediately with:
+#### Platform-Specific Setup
 
-    aptly
+##### macOS

+This guide explains how to run aptly tests on macOS, including Apple Silicon (M1/M2) machines.
 
-    ~/go/bin/aptly
+###### Prerequisites
 
-### Unit-tests
+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

+      - 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

-### Style Checks
+### Continuous Integration (CI)
 
-Style checks could be run with:
+aptly uses GitHub Actions for continuous integration. The CI pipeline includes:
 
-    make check
+- **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)
 
-aptly is using [gometalinter](https://github.com/alecthomas/gometalinter) to run style checks on Go code. Configuration
-for the linter could be found in [linter.json](linter.json) file. Running linters might take considerable amount of time
-unfortunately, but usually warning reported by linters hint at real code issues.
+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
 
-Python code (system tests) are linted with [flake8 tool](https://pypi.python.org/pypi/flake8).
+#### Testing CI Locally with act
 
-### Vendored Code
+You can test GitHub Actions workflows locally using [act](https://github.com/nektos/act):
 
-aptly is using Go vendoring for all the libraries aptly depends upon. `vendor/` directory is checked into the source
-repository to avoid any problems if source repositories go away. Go build process will automatically prefer vendored
-packages over packages in `$GOPATH`.
+```bash
+# Install act
+brew install act              # macOS
+# or
+curl https://raw.githubusercontent.com/nektos/act/master/install.sh | sudo bash  # Linux
 
-If you want to update vendored dependencies or to introduce new dependency, use [dep tool](https://github.com/golang/dep).
-Usually all you need is `dep ensure` or `dep ensure -update`.
+# 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`

+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
 
-    $ apt-key adv --keyserver keys.gnupg.net --recv-keys 9E3E53F19C7DE460
+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)::
 
-If you would like to use nightly builds (unstable), please use following repository::
+    wget -O /etc/apt/keyrings/aptly.asc https://www.aptly.info/pubkey.txt
 
-    deb http://repo.aptly.info/ nightly main
+Define Release APT sources in ``/etc/apt/sources.list.d/aptly.list``::
 
-Binary executables (depends almost only on libc) are available for download from `Bintray <http://dl.bintray.com/smira/aptly/>`_.
+    deb [signed-by=/etc/apt/keyrings/aptly.asc] http://repo.aptly.info/release DIST main
 
-If you have Go environment set up, you can build aptly from source by running (go 1.7+ required)::
+Where DIST is one of: ``buster``, ``bullseye``, ``bookworm``, ``focal``, ``jammy``, ``noble``
 
-    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
-    make install
+Install aptly packages::
 
-Binary would be installed to ```$GOPATH/bin/aptly``.
+    apt-get update
+    apt-get install aptly
+    apt-get install aptly-api  # REST API systemd service
 
-Contributing
-------------
+CI Builds
+~~~~~~~~~~
 
-Please follow detailed documentation in `CONTRIBUTING.md <CONTRIBUTING.md>`_.
+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
+
+Where DIST is one of: ``buster``, ``bullseye``, ``bookworm``, ``focal``, ``jammy``, ``noble``
+
+Note: same gpg key is used as for the Upstream Debian Packages.

+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
