Helper Examples

getFileMappings

Example:

from jetstream.helper import Helper

files = ['/repo/project/readme.txt', '/repo/project/build/make', '/repo/project/src/main.cpp']

helper = Helper(None)
helper.getFileMappings(files)
# {'/repo/project/build/make': '/repo/project/build/make',
#  '/repo/project/readme.txt': '/repo/project/readme.txt',
#  '/repo/project/src/main.cpp': '/repo/project/src/main.cpp'}

helper.getFileMappings(files, relative_to='/repo/project')
# {'/repo/project/build/make': 'build/make',
#  '/repo/project/readme.txt': 'readme.txt',
#  '/repo/project/src/main.cpp': 'src/main.cpp'}

getFilteredManifestFiles

Example:

from jetstream import Jetstream
from jetstream.helper import Helper

def _text_files(fileMappings):
    return fileMappings['srcPath'].endswith('.txt')

jetstream = Jetstream()
api = jetstream.api()
api.connect()

helper = Helper(api)
# Submit the predicate to getFilteredManifestFiles().
manifests = helper.getFilteredManifestFiles(_text_files)
# {'errorMessage': None,
# 'fileMappings': [{'destPath': 'setup/README.txt',
#                   'fileSize': 183,
#                   'isEmptyDir': False,
#                   'srcPath': '/depot/project/setup/README.txt'},
#                  {'destPath': 'docs/requirements.txt',
#                   'fileSize': 2238,
#                   'isEmptyDir': False,
#                   'srcPath': '/depot/project/docs/requirements.txt'}],
# 'manifestId': '3dcbe0ef1bb143ad0100000000000003',
# 'processing': False,
# 'status': 'complete',
# 'totalFiles': 195,
# 'totalSize': 6428287}]

Example:

def find_file_by_name(name):
    # Use a case-insensitive regular expression.
    _r = re.compile(name, re.I)
    # Define a predicate that compares 'srcPath'
    _fltr = lambda fileMappings: _r.search(fileMappings['srcPath'])
    with Jetstream().api() as api:
        helper = Helper(api)
        # Submit the predicate to getFilteredManifestFiles().
        manifests = helper.getFilteredManifestFiles(_fltr)
    return manifests

find_file_by_name('index.html')
# [{'errorMessage': None,
# 'fileMappings': [{'destPath': '/docs/_build/html/index.html',
#                   'fileSize': 14373,
#                   'isEmptyDir': False,
#                   'srcPath': '/project/serendipity/docs/_build/html/index.html'}],
# 'manifestId': '3dcbe0ef1bb143ad0100000000000011',
# 'processing': False,
# 'status': 'complete',
# 'totalFiles': 647,
# 'totalSize': 245631984}]

getTransferFlags

Example:

from jetstream.helper import Helper

helper = Helper(None)
helper.getTransferFlags(readEnabled=True, writeEnabled=True)
# 3
helper.getTransferFlags(readEnabled=True, writeEnabled=False)
# 1

sendFiles

Example:

import getpass
from jetstream import Jetstream
from jetstream.helper import Helper

jetstream = Jetstream()
api = jetstream.api()
api.connect()
destination = api.send.createDestination("localhost", sendRateMax=12345)

helper = Helper(api)

sourcePath = '/path/to/local/file.txt'
destinationPath = 'uploads'
transferObject = helper.sendFiles(destination, sourcePath, destinationPath, userName=getpass.getuser(), password=getpass.getpass())

progress = transferObject.getProgress()
status = transferObject.getStatus()
transfer = transferObject.getRawStats()
