Submodules

oslo_reports.views.text.generic module

Provides generic text views

This modules provides several generic views for serializing models into human-readable text.

class oslo_reports.views.text.generic.BasicKeyValueView

Bases: object

A Basic Key-Value Text View

This view performs a naive serialization of a model into text using a basic key-value method, where each key-value pair is rendered as “key = str(value)”

class oslo_reports.views.text.generic.KeyValueView(indent_str=' ', key_sep=' = ', dict_sep=' = ', list_sep=' = ', anon_dict='[dict]', before_dict=None, before_list=None)

Bases: object

A Key-Value Text View

This view performs an advanced serialization of a model into text by following the following set of rules:

keytext

key = text

rootkeyMapping

rootkey =
  serialize(key, value)

keySequence

key =
  serialize(item)

Parameters

• indent_str (str) – the string used to represent one “indent”

• key_sep (str) – the separator to use between keys and values

• dict_sep (str) – the separator to use after a dictionary root key

• list_sep (str) – the separator to use after a list root key

• anon_dict (str) – the “key” to use when there is a dict in a list (does not automatically use the dict separator)

• before_dict (str or None) – content to place on the line(s) before the a dict root key (use None to avoid inserting an extra line)

• before_list (str or None) – content to place on the line(s) before the a list root key (use None to avoid inserting an extra line)

class oslo_reports.views.text.generic.MultiView

Bases: object

A Text View Containing Multiple Views

This view simply serializes each value in the data model, and then joins them with newlines (ignoring the key values altogether). This is useful for serializing lists of models (as array-like dicts).

class oslo_reports.views.text.generic.TableView(column_names, column_values, table_prop_name)

Bases: object

A Basic Table Text View

This view performs serialization of data into a basic table with predefined column names and mappings. Column width is auto-calculated evenly, column values are automatically truncated accordingly. Values are centered in the columns.

Parameters

• column_names ([str]) – the headers for each of the columns

• column_values ([str]) – the item name to match each column to in each row

• table_prop_name (str) – the name of the property within the model containing the row models

oslo_reports.views.text.header module

Text Views With Headers

This package defines several text views with headers

class oslo_reports.views.text.header.HeaderView(header)

Bases: object

A Text View With a Header

This view simply serializes the model and places the given header on top.

Parameters

header – the header (can be anything on which str() can be called)

class oslo_reports.views.text.header.TitledView(title)

Bases: oslo_reports.views.text.header.HeaderView

A Text View With a Title

This view simply serializes the model, and places a preformatted header containing the given title text on top. The title text can be up to 64 characters long.

Parameters

title (str) – the title of the view

FORMAT_STR = '========================================================================\n===={0: ^64}====\n========================================================================'

oslo_reports.views.text.process module

Provides process view

This module provides a view for visualizing processes in human-readable form

class oslo_reports.views.text.process.ProcessView(path=None, text=None)

Bases: oslo_reports.views.jinja_view.JinjaView

A Process View

This view displays process models defined by oslo_reports.models.process.ProcessModel

VIEW_TEXT = "Process {{ pid }} (under {{ parent_pid }}) [ run by: {{ username }} ({{ uids.real|default('unknown uid') }}), state: {{ state }} ]\n{% for child in children %} {{ child }}{% endfor %}"

oslo_reports.views.text.threading module

Provides thread and stack-trace views

This module provides a collection of views for visualizing threads, green threads, and stack traces in human-readable form.

class oslo_reports.views.text.threading.GreenThreadView

Bases: object

A Green Thread View

This view displays a green thread provided by the data model oslo_reports.models.threading.GreenThreadModel

FORMAT_STR = '------{thread_str: ^60}------\n{stack_trace}'

class oslo_reports.views.text.threading.StackTraceView(path=None, text=None)

Bases: oslo_reports.views.jinja_view.JinjaView

A Stack Trace View

This view displays stack trace models defined by oslo_reports.models.threading.StackTraceModel

VIEW_TEXT = '{% if root_exception is not none %}Exception: {{ root_exception }}\n------------------------------------\n\n{% endif %}{% for line in lines %}\n{{ line.filename }}:{{ line.line }} in {{ line.name }}\n {% if line.code is not none %}`{{ line.code }}`{% else %}(source not found){% endif %}\n{% else %}\nNo Traceback!\n{% endfor %}'

class oslo_reports.views.text.threading.ThreadView

Bases: object

A Thread Collection View

This view displays a python thread provided by the data model oslo_reports.models.threading.ThreadModel # noqa

FORMAT_STR = '------{thread_str: ^60}------\n{stack_trace}'
