The internal structure for the map type has changed between some Go versions. The current parsing logic can't handle Go 1.7 to 1.13. Due to this, if the the map has methods, the parser reads bad data. This bug only affects the develop branch and not the stable branch.
Extract build id from the file and provide it as an attribute.
The daily cron job is currently timing out after 6 hours. It appears to be due to the moduledata code generation. It has currently been disabled.

As https://github.com/codecov/codecov-action said:
Deprecation of v1
As of February 1, 2022, v1 has been fully sunset and no longer functions
Due to the deprecation of the underlying bash uploader, the Codecov GitHub Action has released v2/v3 which will use the new uploader. You can learn more about our deprecation plan and the new uploader on our blog.
We will be restricting any updates to the v1 Action to security updates and hotfixes.
But update to v2/v3 required a token from codecov, which can only be set by maintainer. It's hard to create to pr to fix this.
I'm playing with some golang compiler arguments, and I found a linkmode=external buildmode=pie

I am using gore to create my own project gsv, but my project is released under the Mozilla Public License 2.0, and I'm not sure if this is compatible with the AGPL that gore uses, so I'd like to get an explicit permit from the author for this use.
Thank you sincerely for your work on gore.

in goroot.go:357
, subpath := fmt.Sprintf("/src/%s", v.Name)
, subpath
will be /src/:packageName
.
in goroot.go:358
, *github.com/goretk/gore.Package.Filepath
will return\usr\local\go\src\:packageName
.
so in goroot.go:358
, if strings.HasSuffix(v.Filepath, subpath)
will alway be false.
if i use this statement subpath := filepath.Join("/src", v.Name)
, it will get expect result.
but, in goroot.go:359
, it will return \usr\local\go
, not equal expectGoRoot
in goroot_test.go
in my project, i use filepath.ToSlash
to deal with the result return from GetGoRoot
. i have no idea, if use filepath.ToSlash
in goroot.go:360
, will it adversely affect the project?
i run go test
, it seems good.

When running the following script on a installation of pygore on a debian system i sometimes see erroneous values for kind. These are parsed correctly on a windows installation, using the same binary. I've verified the binaries are not corrupted by checking their hashes.
import pygore
import sys
testfile = sys.argv[1]
f = pygore.GoFile(testfile)
c = f.get_compiler_version()
types = f.get_types()
f.close()
for t in types:
val, = t.kind
if val > 30 :
print(val)

Go version I was using: Go 1.13 linux/amd64
I was testing out gore today, and came across a curious bug. I compiled the code below, with no special flags: go build -trimpath -o test.bin main.go
I then ran the file against itself ./test.bin test.bin
, and this error occured:

I also came across this error running this code against various other Go ELF files on my system, so it isn't unique to this file.
Code mentioned above:
package main
import (
"fmt"
"os"
"path"
"github.com/goretk/gore"
)
func main() {
file, err := gore.Open(os.Args[1])
if err != nil {
panic(err)
}
packages, err := file.GetPackages()
if err != nil {
panic(err)
}
types, err := file.GetTypes()
if err != nil {
panic(err)
}
symbols := make([]string, (len(packages) + len(types)*2))
for _, goType := range types {
symbols = append(symbols, path.Join(goType.PackagePath, goType.Name))
}
for _, pkg := range packages {
for _, method := range pkg.Methods {
symbols = append(symbols, path.Join(method.PackageName, method.Name))
}
for _, function := range pkg.Functions {
symbols = append(symbols, path.Join(function.PackageName, function.Name))
}
}
for _, symbol := range symbols {
fmt.Println(symbol)
}
}
EDIT: ran compiled binary through redress
just to make sure I was using gore correctly, and as I thought it panic'd with the same error.
As described in golang/go#65232, gosym.NewLineTable
should be used with the value of symbol runtime.text
but not just use the start of .text
segment, which was used by gore right now.
I have no idea how to implement a search for runtime.text
in the stripped binary, but at least we can show a warning like the offset in func can be incorrect in cgo binary
right now.
Due to some logic bugs, not all information is extracted correctly.
The estimate of function source code lines uses a deprecated function. Update to use the new functions provided by the standard library and improve its accuracy.

Support for parsing types from big endian files.
How can I overwrite/replace the extracted information in the compiled binary? e.g BuildID, package names etc. I didn't see any exposed methods that can do this.
