This commit converts the dependency management from Godeps to the vendor folder, also switching the tool from godep to trash. Since the upstream tool lacks a few features proposed via a few PRs, until those PRs are merged in (if), use github.com/karalabe/trash. You can update dependencies via trash --update. All dependencies have been updated to their latest version. Parts of the build system are reworked to drop old notions of Godeps and invocation of the go vet command so that it doesn't run against the vendor folder, as that will just blow up during vetting. The conversion drops OpenCL (and hence GPU mining support) from ethash and our codebase. The short reasoning is that there's noone to maintain and having opencl libs in our deps messes up builds as go install ./... tries to build them, failing with unsatisfied link errors for the C OpenCL deps. golang.org/x/net/context is not vendored in. We expect it to be fetched by the user (i.e. using go get). To keep ci.go builds reproducible the package is "vendored" in build/_vendor.

# The unix package provides access to the raw system call
|
|
# interface of the underlying operating system. Porting Go to
|
|
# a new architecture/operating system combination requires
|
|
# some manual effort, though there are tools that automate
|
|
# much of the process. The auto-generated files have names
|
|
# beginning with z.
|
|
#
|
|
# This script runs or (given -n) prints suggested commands to generate z files
|
|
# for the current system. Running those commands is not automatic.
|
|
# This script is documentation more than anything else.

# * asm_${GOOS}_${GOARCH}.s
|
|
#
|
|
# This hand-written assembly file implements system call dispatch.
|
|
# There are three entry points:
|
|
#
|
|
# func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
|
|
# func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr);
|
|
# func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
|
|
#
|
|
# The first and second are the standard ones; they differ only in
|
|
# how many arguments can be passed to the kernel.
|
|
# The third is for low-level use by the ForkExec wrapper;
|
|
# unlike the first two, it does not call into the scheduler to
|
|
# let it know that a system call is running.
|
|
#
|
|
# * syscall_${GOOS}.go
|
|
#
|
|
# This hand-written Go file implements system calls that need
|
|
# special handling and lists "//sys" comments giving prototypes
|
|
# for ones that can be auto-generated. Mksyscall reads those
|
|
# comments to generate the stubs.
|
|
#
|
|
# * syscall_${GOOS}_${GOARCH}.go
|
|
#
|
|
# Same as syscall_${GOOS}.go except that it contains code specific
|
|
# to ${GOOS} on one particular architecture.
|
|
#
|
|
# * types_${GOOS}.c
|
|
#
|
|
# This hand-written C file includes standard C headers and then
|
|
# creates typedef or enum names beginning with a dollar sign
|
|
# (use of $ in variable names is a gcc extension). The hardest
|
|
# part about preparing this file is figuring out which headers to
|
|
# include and which symbols need to be #defined to get the
|
|
# actual data structures that pass through to the kernel system calls.
|
|
# Some C libraries present alternate versions for binary compatibility
|
|
# and translate them on the way in and out of system calls, but
|
|
# there is almost always a #define that can get the real ones.
|
|
# See types_darwin.c and types_linux.c for examples.
|
|
#
|
|
# * zerror_${GOOS}_${GOARCH}.go
|
|
#
|
|
# This machine-generated file defines the system's error numbers,
|
|
# error strings, and signal numbers. The generator is "mkerrors.sh".
|
|
# Usually no arguments are needed, but mkerrors.sh will pass its
|
|
# arguments on to godefs.
|
|
#
|
|
# * zsyscall_${GOOS}_${GOARCH}.go

#
|

# Generated by mksyscall.pl; see syscall_${GOOS}.go above.
