Jakob Unterwurzacher b2abb0484f Drop workarounds for Go 1.11 and Go 1.12 2021-08-18 17:48:38 +02:00
Jakob Unterwurzacher 3a1f009c1a Add contrib/atomicrename
$ ./contrib/atomicrename/atomicrename -h
atomicrename creates 100 "src" files in the current directory, renames
them in random order over a single "dst" file while reading the "dst"
file concurrently in a loop.

Progress and errors are reported as they occour in addition to a summary
printed at the end. cifs and fuse filesystems are known to fail, local
filesystems and nfs seem ok.

See for background info.

Jakob Unterwurzacher fe340477b2 build.bash: show "go mod edit -replace" in version string
If you do something like this,

  go mod edit -replace

the version string of the resulting binary should reflect that.

to fix a crash reported in :

  2019/10/30 17:14:16 Unknown opcode 2016
  panic: runtime error: invalid memory address or nil pointer dereference
  [signal SIGSEGV: segmentation violation code=0x1 addr=0x20 pc=0x508d38]

This patch is only in the v2.x.x branch. Upgrade to v2, as the
old API is also supported there.


  git grep hanwen/go-fuse | grep -v hanwen/go-fuse/v2

to check for forgotten references comes back clean.

The case of a git repo without any tags used to fail

  fatal: No names found, cannot describe anything.

Now we continue, using "[no_tags_found]" as the
version string.

Sebastian Lackner 2a010263f6 build.bash: Escape LDFLAGS before passing them to 'go build'.
This ensures that ./build.bash still works when the LDFLAGS environment
variable contains multiple options, e.g., LDFLAGS="-lpthread -lm". The
correct way of passing multiple options is discussed here:

For some unknown reason, the method only works when -extldflags is the
last argument - is this a bug in Go?

Jakob Unterwurzacher bf241ce77e build.bash: use -trimpath for reproducible builds
Support both Go 1.7...1.9 and Go 1.10 by checking the
version and using the appropropriate syntax.

We trim GOPATH/src and use both -gcflags and -asmflags like Debian does in
ab2bbcfc00/lib/Debian/Debhelper/Buildsystem/ (L465) .

Jakob Unterwurzacher e4fdb42496 build.bash: implement "you need Go 1.5" lockout in pure Go
As noticed by @riking, the logic in the bash script will break
when Go 1 version numbers reach double-digits.

Instead, use a build tag "!go1.5" to cause a syntax error:

  $ /opt/go1.4.3/bin/go build
  can't load package: package
  go1.4.go:5:1: expected 'package', found 'STRING' "You need Go 1.5 or higher to compile gocryptfs!"

Jakob Unterwurzacher 1dcafb99ff main: drop "on-disk format" from -version output, add Go version
As v0.4 introduced ext4-style feature flags, the on-disk format version
is unlinkely to change. Drop it from the version output to reduce
clutter. Use "gocryptfs -version -debug" to see it.

Add the Go version string because only Go 1.6 and newer have an optimized
AES-GCM implementation. This will help users to understand the performance
of their build.
