How Can I Remove File Paths from Go Binaries\' TEXT Directives Without Using the `strip` Tool?

Removing File Paths from TEXT Directives in Compiled Go Binaries

The need arises to eliminate file path information from TEXT directives within compiled Go binaries. This question seeks a solution that doesn't involve the use of the 'strip' tool.

Solution: Employing -trimpath Flags

The recommended approach involves utilizing the '-trimpath' flags when invoking 'go build'. By passing '-trimpath' to '-gcflags' and '-asmflags', extraneous path information can be stripped from the resulting elf binary.

Here's a modified example of the 'go build' command incorporating the '-trimpath' flags:

CGO_ENABLED=0 go build -v -a -ldflags="-w -s" \
    -gcflags=-trimpath=/Users/myuser/dev/go/src \
    -asmflags=-trimpath=/Users/myuser/dev/go/src \
    -o ./fooapi spikes/mongoapi.go

Verification:

To confirm the effectiveness of this solution, run 'go tool objdump' on the modified binary:

$ go tool objdump ./fooapi
.
.
TEXT main.init(SB) api/spikes/mongoapi.go
mongoapi.go:60  0x12768c0   65488b0c25a0080000  GS MOVQ GS:0x8a0, CX
mongoapi.go:60  0x12768c9   483b6110        CMPQ 0x10(CX), SP
mongoapi.go:60  0x12768cd   7663            JBE 0x1276932
.
.

Additional Notes:

It's essential to note that while the 'strip' tool has been reported to resolve this issue, some within the Go community still express concerns regarding its reliability. Instances of unknown and unpredictable bugs have been encountered, as documented in various forums and discussions.
