symstore 0.2.6

publish PDB and PE files to symbols store

A python module and command line utility for publishing windows debugging symbols to symbols store. The symbols published in this format can be consumed by the common development tools for windows, such as Visual Studio and WinDbg. See Using SymStore for more information on windows symbols store.

Currently it is possible to publish PDB and PE (exe and dll) files to a local file system.

Installing

Install with pip utility by running:

$ pip install symstore

This will install the command line utility symstore as well as python module symstore.

It is also possible to install symstore package from source code. For example, clone symstore’s git repository with:

$ git clone <repo-url> symstore

and install it with pip:

$ pip install symstore/

Using

command line

Use the symstore command to publish the symbols. Run symstore --help for details.

Python module

To publish symbols programmatically use the symstore module. See symstore/command_line.py for an example on how to use the API.

Compression

The symstore package supports compressing the data files when publishing them. This can lead to significant reduction of data that needs to be transferred while accessing symbols.

The compression mode is activated with --compress or -z flag to symstore command line utility.

Symstore uses the native gcab library via introspection to compress data. The required packages must be available on the system for the compression mode to work.

On ubuntu 18.04, install following packages:

• gir1.2-gcab-1.0

• python-gi

On ubuntu 16.04, install following packages:

• gir1.2-libgcab-1.0

• python-gi

In case symstore is not able to locate python-gi and gir packages while compression mode is requested, following error message will be displayed:

gcab module not available, compression not supported
