Manifest Ingest

Author: Tim Santor [e-mail]

Overview

Download a project JSON manifest and its media files via S3, SFTP or HTTP. This tool was developed for internal use on all X Studios interactive installations which need to have the ability to run “offline” when there is no active network connection.

Installation

pip install manifest-ingest

Or if you want to install a development version:

pip install git+https://bitbucket.org/xstudios/manifest-ingest.git@tag

Usage

Create a Config file

Create a config file at ~/manifest-ingest.cfg:

[default]
; API endpoint which returns JSON
api_url = http://192.168.1.69:8000/api/v1/music/playlist/
; Auth token needed to access the API (optional)
api_token = API_TOKEN
; Regex of key names to search for
keys = (audio_url|artwork_url)
; Override the default manifest filename (optional)
manifest_filename = manifest.json
; Local directory to place downloaded files
local_dir = ~/target/dir/downloads
; Where to place the log file for the application
log = ~/target/dir/manifest-ingest.log
; Max retries to make failed network request before giving up
max_retries = 5
; Base URL for relative paths
base_url = http://192.168.1.69:8000
; Concurrent downloads (number of cores * 2 is usually best)
concurrent_downloads = 4

[s3]
profile_name = default
bucket_name = BUCKET_NAME
; Compare MD5 hash of local file with remote file
compare_md5 = true

[sftp]
server = 192.168.1.100
username = USERNAME
password = PASSWORD
; Remote directory on server to prepend to file URLs in manifest
remote_dir = /var/sic_admin

[post_download]
; Command to run when complete
command = osascript -e 'tell application "Safari" to activate'

NOTE: The config file can be located anywhere that is readable by
the user. The ``s3``, ``sftp`` and ``post_download`` sections are
optional.

Usage

manifest-ingest --config=~/manifest-ingest.cfg

Run at Startup (Mac)

Create a plist file as /Library/LaunchAgents/com.user.manifestingest.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.user.manifestingest</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/local/bin/manifest-ingest</string>
        <string>--config</string>
        <string>~/config/manifest-ingest.cfg</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
</dict>
</plist>

Then run:

launchctl load /Library/LaunchAgents/com.user.manifestingest.plist

Version History

• 0.0.1 - Initial release
• 0.0.2 - Added saving and backup of manifest locally
• 0.0.3 - Graceful error handling for when a remote file doesn’t exist and we attempt to download it
• 0.0.4 - Added config option to launch command line app when download finished
• 0.0.5 - Added alternate media URL strip method
• 0.0.6 - Major refactor to make more configurable
• 0.0.7 - Added single package entry point (all script entry points us same config) and Removed manifest-quickstart
• 0.0.8 - Fixed bug where we expected a api_token in the config (not always needed)
• 0.0.9 - Fixed bug with config setup importing from wrong package
• 0.1.0 - Fixed bug with run_command call typo
• 0.1.1 - Fixed url path removal from JSON and correct os paths
• 0.1.2 - Fixed remote path bug on Windows
• 0.1.3 - Added elapsed time to log
• 0.2.0 - Key names are now a regex which is more flexible & powerful
• 0.2.1 - Fixed bug where local filename would be striped of the word “media”
• 0.2.2 - Additional logging
• 0.2.3 - Removed some logging clutter
• 0.2.4 - If manifest is empty (eg - {}), then we abort and do not launch post_download commands
• 0.2.5 - Use Keychain (OSX) or Credential Manager (Windows) to get SFTP password
• 0.2.6 - When executing manifest-sftp over SSH, Keychain/Credential Manager do not provide the password so we added the ability to manually provide a password via the -p or --password argument on the command line (use with caution)
• 0.2.7 - Due to complications with running via command line, we removed the Keychain/Credential Manager support. You may now pass passwords via Base64 to at least thwart over the shoulder attacks. Also changed the way we execute the post download command to be non-blocking.
• 0.2.8 - Improved connection and SSH exception handling and added connection retries up to a max number of times.
• 0.2.9 - Lock in version of pysftp to 0.2.8 due to 0.2.9 HostKeys issue.
• 0.3.0 - Revert to original manifest on SFTP login failure as we won’t be able to download the files in the manifest.
• 0.3.1 - Bug fix with creating remote path correctly on Windows.
• 0.3.2 - After a failed SSH attempt, revert manifest to original and run post_download.
• 0.3.3 - Added manifest_filename config so we can save to custom named manifest file.
• 0.3.4 - Lock in version of pysftp to 0.2.8 due to 0.2.9 HostKeys issue…again.
• 0.3.5 - Added manifest-s3 to handle manifests of S3 files.
• 0.3.6 - Update the way we save the manifest with s3 manifests.
• 0.4.0 - Complete refactor. Single entrypoint of manifest-ingest. Via config can handle S3, SFTP and HTTP manifest URL downloads.
• 0.4.1 - Added ability to compare local and remote MD5 hashes to determine if a file is newer on S3.
• 0.4.2
  • Changed Changed the way we look for keys with URLs (absolute or relative) to regex.
  • Changed Changed the way we strip URL prefixes to make paths relative (to to the download directory) to regex.
  • Added Added ability to specify AWS credenttial profile to use for S3 in config.
• 0.4.3 - Added multiprocessing to speed up downloads
