As several of our users have noticed, IDA 7.4 Windows installer refuses to use Python 3.8.0 if you installed it. You can usually observe output similar to following: ———- Checking installs from “Python Software Foundation” Checking “Python 3.8 (64-bit)” (3.8) Found: “C:\Program Files\Python38\” (version: 3.8.0 (’38’)) Ignoring unusable Python 3.8.0 No Python installations were found ———- So why exactly is 3.8.0 “unusable”? Well, […]
IDA 7.4 will still ship with IDAPython for Python 2.7 by default, but users will now have the opportunity to pick IDAPython for Python 3.x at installation-time!
IDA 7.4 will ship with the IDAPython “IDA 6.x” compatibility layer off by default. Please see this article for more information!
We posted an addendum to the release notes for IDA 7.2: The Mac Rundown. It dives much deeper into the Mac-specific features introduced in 7.2, and should be great reference material for users interested in reversing the latest Apple binaries. It’s packed full of hints, tricks, and workarounds. We hope you will find it quite useful! […]
Intended audience IDAPython developers who enjoy the occasional headache, leaky abstraction enthousiasts, or simply the curious. TL;DR IDAPython wraps C++ types, and the lifecycle of C++ objects (and in particular members of larger objects) is not necessarily the same as that of the Python wrapper object that is wrapping it. The problem One of our users reported IDA crashes when […]
Intended audience IDAPython plugins, loaders or processor modules developers. The problem Until now, IDAPython would load all loaders, processor modules & plugins in the ‘__main__’ module. This causes namespace pollution, which can sometimes leads to very obscure errors. The solution Starting with version 7.1, IDA will import plugins, loaders & processor modules in their own, separate Python modules. The names of those […]
With IDA 7.0 switching fully to native x64 architecture, we also switched to the x64 Python which brought some new issues but also exposed some we’ve seen before. This post tries to summarize the most common issues we’ve seen our users encounter as well as suggestions about how to fix them or at […]
Background Contrary to previous versions that shipped with Qt 4.8.4, IDA 6.9 ships with Qt 5.4.1 and as we announced some time ago, this will force some changes for plugin writers who were using IDAPython + PySide in order to build custom interfaces. What’s more, in addition to the Qt4 -> Qt5 switch, we have also […]
Intended audience Plugin writers, either using the C SDK or IDAPython, who would like to add actions/commands to IDA UI in order to augment its capabilities. Rationale: before 6.7 APIs galore Depending on what type of context you were in, various APIs were available to you: Want to add a main menu item? add_menu_item(const char *menupath, const char *name, const char […]
Target audience You may want to read this if you have been writing an IDA C++ plugin, that itself uses the CPython runtime. Prior art In 2010, Elias Bachaalany wrote a blog post about extending IDAPython: http://www.hexblog.com/?p=126 Note that this is not about writing your own plugins in Python. Rather, that blog post instruct on how you may […]
