graphlog: refactor revset() to return revisions
When --follow and --rev are passed, --follow actual behaviour depends on the
input revision sequence defined by --rev. If --rev is not passed, the default
revision sequence depends on the presence of --follow. It means the revision
sequence generation is part of log logic and must be wrapped. The issue
described above is fixed in following patches.
import sys
globalvars = {}
localvars = {}
lines = sys.stdin.readlines()
while lines:
l = lines.pop(0)
if l.startswith('SALT'):
print l[:-1]
elif l.startswith('>>> '):
snippet = l[4:]
while lines and lines[0].startswith('... '):
l = lines.pop(0)
snippet += "\n" + l[4:]
c = compile(snippet, '<heredoc>', 'single')
try:
exec c in globalvars, localvars
except Exception, inst:
print repr(inst)
