Open, extensible Python injector/profiler/analyzer
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.
pip3 install pptop
- Python: 3.5+ is required, as ppTOP uses asyncio
- Injection into running processes requires gdb (present in almost all Linux distributions)
- Only Linux systems are currently supported
ppTOP can be injected into any running Python process
or you can load Python program manually and profile its launch
To launch a program, press Ctrl+L or specify -w sec param in command line args to launch it automatically after the specified delay.
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 can be paused. In case of problems, any plugin can be re-injected at any time.
Plugins and keyboard shortcuts are configured by default in ~/.pptop/pptop.yml file (created automatically at first launch).
- 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 :)
With "`" button, remote Python console can be opened. It has no full functionality like a standard Python console, but supports all frequently used features, like importing modules, defining functions and variables, executing functions and loops etc.
Console has own remote globals, which are preserved until ppTOP is quit and injected server is terminated.
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.
- More plugins
- Advanced filtering
- Data snapshots
- Step-by-step debugger
- JSON API, web interface
p.s. Code in master can be completely broken, install with pip only.
