Pkg.RPM — API for parsing RPM archives

Overview

The Pkg.RPM module contains the API for parsing RPM archives.

Parsing an RPM Archive

The following code example demonstrates how to parse an RPM archive:

from Pro.Core import *
from Pkg.RPM import *

def parseRPMArchive(fname):
    c = createContainerFromFile(fname)
    if c.isNull():
        return
    obj = RPMObject()
    if not obj.Load(c) or not obj.ParseArchive():
        return
    n = obj.GetEntryCount()
    for i in range(n):
        entry = obj.GetEntry(i)
        if entry == None:
            break
        # skip directories
        if not obj.IsFile(entry):
            continue
        print("file name:", entry.name)
        # retrieves the file data as NTContainer
        fc = obj.GetEntryData(entry)

Module API

Classes:

RPMObject()

This class represents an RPM archive.

class RPMObject

Bases: Pro.Core.CFFObject

This class represents an RPM archive.

Methods:

DumpHeaders(out)	Dumps the headers to a text stream.
GetEntry(i)	Retrieves an entry by its index.
GetEntryCount()	Returns the number of entries present in the archive.
GetEntryData(i[, wo])	Retrieves the data of an entry.
GetHeaders()	Returns the headers as a dictionary.
IsDirectory(i)	Checks whether an entry is a directory.
IsFile(i)	Checks whether an entry is a file.
ParseArchive()	Parses the archive.

DumpHeaders(out: Pro.Core.NTTextStream) → None

Dumps the headers to a text stream.

Parameters

out (NTTextStream) – The output text stream.

See also GetHeaders().

GetEntry(i: int) → Any

Retrieves an entry by its index.

Parameters

i (int) – The entry index.

Returns

Returns the requested entry if successful; otherwise returns None.

Return type

Any

GetEntryCount() → int

Returns

Returns the number of entries present in the archive.

Return type

int

GetEntryData(i: int, wo: Optional[Pro.Core.NTIWait] = None) → Pro.Core.NTContainer

Retrieves the data of an entry.

Parameters

• i (int) – The entry index.

• wo (NTIWait) – Optional wait object for the operation.

Returns

Returns the data if successful; otherwise returns an invalid container.
