This allows us to update this dependency on our schedule which is important because the module relies on manually updating the known list of Go versions to function correctly. Forking allows us to keep this up to date ourselves and possibly create a new system to prevent having to perform this manual step in the future.

Package gore is a library for analyzing Go binaries.
|
|
|
|
Only little endian architectures are supported.
|
|
|
|
Go compiler
|
|
|
|
The library has functionality for guessing the compiler version
|
|
used. It searches the binary for the identifiable string left
|
|
by the compiler. It is not perfect, so functionality for assuming
|
|
a specific version is also provided. The version strings used are
|
|
identical to the identifiers. For example version "1.10.1" is
|
|
represented as "go1.10.1" and version "1.10" is represented as
|
|
"go1.10"
|
|
|
|
Function recovery
|
|
|
|
Function information is recovered from the pclntab. Information
|
|
that is recovered includes: function start and end location in
|
|
the text section, source file. The library also tries to estimate
|
|
the first and last line number in the source file for the function.
|
|
The methods recovered includes the receiver. All functions and
|
|
methods belong to a package. The library tries to classify the
|
|
type of package. If it is a standard library package, 3rd-party
|
|
package, or part of the main application. If it unable to classify
|
|
the package, it is classified as unknown.
|
|
|
|
Type recovery
|
|
|
|
The types in the binary are parsed from the "typelink" list. Not
|
|
all versions of Go are supported equally. Versions 1.7 and later
|
|
are fully supported. Versions 1.5 and 1.6 are partially supported.
|
|
Version prior to 1.5 are not supported at all at the moment.
|
|
|
|
Example code
|
|
|
|
Extract the main package, child packages, and sibling packages:
|
|
|
|
f, err := gore.Open(fileStr)
|
|
pkgs, err := f.GetPackages()
|
|
|
|
Extract all the types in the binary:
|
|
|
|
f, err := gore.Open(fileStr)
|
|
typs, err := f.GetTypes()
|
|
|
