pptop 0.1.1

Open, extensible Python injector/profiler/analyzer

ppTOP

ppTOP is open, extensible Python injector/profiler/analyzer.

The main idea is to inject a custom code inside Python process (already running or going to be launched) and analyze its behavior with no any code modifications.

Say no to "prints" and garbage in debug logs - now you have ppTOP. A modern MRI scanner for Python.

Installation

  pip3 install pptop

• Python: 3.5+ is required, as ppTOP uses asyncore
• Install gdb
• Only Linux systems are currently supported

Features

ppTOP can be injected into any running Python process

or you can load Python program manually and profile its launch

Data from connected process is collected in real-time and displayed in table-based console UI, which can be easily extended with custom plugins.

All data tables can be scrolled, filtered, new data collection ca be paused. In case of problems, any plugin can be re-injected at any time.

Standard plugins

• env view process OS environment variables
• log inject into all Python loggers and collect log messages
• open_files view process open files
• script_runner launch a custom scripts inside process
• threads view process threads
• vars variable/function watcher
• yappi yappi profiler/plugin

Most of plugins contain 2 parts of code: one collects data inside profiling process, other display it in ppTOP UI. For the profiling process all plug-ins are invisible, safe and unloadable (at least they try their best :)

Console mode

With "`" button, remote Python console can be opened. It has no full functionality like a standard Python console, but it supports all frequently used features, like importing modules, defining functions and variables, executing functions and loops.

Plugin docs

Plugins for ppTOP are very easily to write, it takes only about 100-150 lines of code, as Core API provides all basic functionality: loading data, processing data, sorting data etc.

Plugin development guide is coming very soon.

TODO

• More plugins
• Advanced filtering
• Data snapshots
• Step-by-step debugger
• JSON API, web interface
• Charts

Enjoy! :)

p.s. Code in master can be completely broken, install with pip only.
