8.27. pythonids.dist.blackarch

Module BlackArch Linux [doc].

8.27.1. Description

The securtity distribution based on ArchLinux.

8.27.2. Module

BlackArch Linux releases.

Here BlackArch Linux, which has the same encoding as ArchLinux.

8.27.3. Data

8.27.3.1. RTE_BLACKARCH

Registration of the dist value:

RTE_BLACKARCH        = RTE_LINUX   + custom_dist.add_enum()

8.27.3.2. rte2num

Mapping of the rte string and numeric representation to the numeric value.

8.27.3.3. num2rte

Mapping of the rte numeric representation to the string value.

8.27.3.4. num2pretty

Mapping of the rte numeric representation to the pretty string value.

8.27.3.5. custom_rte_distrel2tuple

Registered callbacks for special handling of custom layout.

custom_rte_distrel2tuple.update(
    {
        RTE_MINIX2: my_distrel2tuple,  #: the callback to be registered
    }
)

8.27.4. Functions

8.27.4.1. my_distrel2tuple

platformids.custom.blackarch.my_distrel2tuple(rte=276917248)[source]
Callback for special version layout of BlackArch Linux, the

same as ArchLinux by Rolling-Versioning, see manuals.

A callback to be used by the function:

platformids.decode_rte_distrel_to_segments(rte=RTE)

Decodes the compressed distrel from the 32bit integer bitmask rte into the corresponding tuple of integer segments.

Parameters

rte –

The comppressed runtime environment identifier bitmask.

default := RTE

Returns

Tuple of Integer values of the encoded segments, either as defined by the default layout, or any known as defined by additional extended and/or custom criteria.

Raises

pass-through –

Examples

decode_rte_distrel_to_segments()
=>  (2019, 4, 1)     # on BlackArch-2019.4.1
