v2016.7-dev 2017-01-06
- Add build target spirv-tools-vimsyntax to generate spvasm.vim, a SPIR-V
assembly syntax file for Vim.
+ - Version string: Allow overriding of wall clock timestamp with contents
+ of environment variable SOURCE_DATE_EPOCH.
- Fixes:
#508: Support compilation under CYGWIN
#517: Fix validation when continue (or case) contstruct is also the head of a
return command_output(
['git', 'rev-parse', 'HEAD'], directory).rstrip().decode()
except:
- return 'unknown hash, {}'.format(datetime.date.fromtimestamp(
- int(os.environ.get('SOURCE_DATE_EPOCH', time.time()))
- ).isoformat())
+ # This is the fallback case where git gives us no information,
+ # e.g. because the source tree might not be in a git tree.
+ # In this case, usually use a timestamp. However, to ensure
+ # reproducible builds, allow the builder to override the wall
+ # clock time with enviornment variable SOURCE_DATE_EPOCH
+ # containing a (presumably) fixed timestamp.
+ timestamp = int(os.environ.get('SOURCE_DATE_EPOCH', time.time()))
+ formatted = datetime.date.fromtimestamp(timestamp).isoformat()
