Functions

binary_helper(suite_id, arch_id, ...)	This function is called in a new subprocess and multiprocessing wants a top level function.
binary_scan_helper(binary_id)	This function runs in a subprocess.
source_helper(suite_id, component_id)	This function is called in a new subprocess and multiprocessing wants a top level function.
source_scan_helper(source_id)	This function runs in a subprocess.

Classes

BinaryContentsScanner(binary_id)	BinaryContentsScanner provides a threadsafe method scan() to scan the contents of a DBBinary object.
BinaryContentsWriter(suite, architecture, ...)	BinaryContentsWriter writes the Contents-$arch.gz files.
ContentsWriter()	Loop over all suites, architectures, overridetypes, and components to write all contents files.
SourceContentsScanner(source_id)	SourceContentsScanner provides a method scan() to scan the contents of a DBSource object.
SourceContentsWriter(suite, component)	SourceContentsWriter writes the Contents-source.gz files.
UnpackedSource(dscfilename[, tmpbasedir])	UnpackedSource extracts a source package into a temporary location and gives you some convinient function for accessing it.

class daklib.contents.BinaryContentsScanner(binary_id: int)

BinaryContentsScanner provides a threadsafe method scan() to scan the contents of a DBBinary object.

scan() → None

This method does the actual scan and fills in the associated BinContents property. It commits any changes to the database. The argument dummy_arg is ignored but needed by our threadpool implementation.

classmethod scan_all(limit=None)

The class method scan_all() scans all binaries using multiple threads. The number of binaries to be scanned can be limited with the limit argument. Returns the number of processed and remaining packages as a dict.

class daklib.contents.BinaryContentsWriter(suite, architecture, overridetype, component)

BinaryContentsWriter writes the Contents-$arch.gz files.

fetch() → Iterable[str]

Yields a new line of the Contents-$arch.gz file in filename order.

formatline(filename, package_list) → str

Returns a formatted string for the filename argument.

get_list() → list[str]

Returns a list of lines for the Contents-$arch.gz file.

query()

Returns a query object that is doing most of the work.

write_file() → None

Write the output file.

writer()

Returns a writer object.

class daklib.contents.ContentsWriter

Loop over all suites, architectures, overridetypes, and components to write all contents files.

classmethod log_result(result) → None

Writes a result message to the logfile.

classmethod write_all(logger, archive_names=None, suite_names=None, component_names=None, force=False)

Writes all Contents files for suites in list suite_names which defaults to all ‘touchable’ suites if not specified explicitely. Untouchable suites will be included if the force argument is set to True.

class daklib.contents.SourceContentsScanner(source_id: int)

SourceContentsScanner provides a method scan() to scan the contents of a DBSource object.

scan() → None

This method does the actual scan and fills in the associated SrcContents property. It commits any changes to the database.

classmethod scan_all(limit=None)

The class method scan_all() scans all source using multiple processes. The number of sources to be scanned can be limited with the limit argument. Returns the number of processed and remaining packages as a dict.

class daklib.contents.SourceContentsWriter(suite, component)

SourceContentsWriter writes the Contents-source.gz files.

fetch()

Yields a new line of the Contents-source.gz file in filename order.

formatline(filename, package_list)

Returns a formatted string for the filename argument.

get_list()

Returns a list of lines for the Contents-source.gz file.

query()

Returns a query object that is doing most of the work.

write_file()

Write the output file.

writer()

Returns a writer object.

class daklib.contents.UnpackedSource(dscfilename: str, tmpbasedir: Optional[str] = None)

UnpackedSource extracts a source package into a temporary location and gives you some convinient function for accessing it.

cleanup() → None

Removes all temporary files.

get_all_filenames() → Iterable[str]

Returns an iterator over all filenames. The filenames will be relative to the root directory.

get_root_directory() → str

Returns the name of the package’s root directory which is the directory where the debian subdirectory is located.

daklib.contents.binary_helper(suite_id: int, arch_id: int, overridetype_id: int, component_id: int)

This function is called in a new subprocess and multiprocessing wants a top level function.

daklib.contents.binary_scan_helper(binary_id: int) → None

This function runs in a subprocess.

daklib.contents.source_helper(suite_id: int, component_id: int)

This function is called in a new subprocess and multiprocessing wants a top level function.

daklib.contents.source_scan_helper(source_id: int) → None

This function runs in a subprocess.
