Subject: Added a --backoff option for syncFileBackend.php
X-Git-Tag: 1.31.0-rc.0~19764^2
X-Git-Url: https://git.cyclocoop.org/%7B%24www_url%7Dadmin/compta/banques/?a=commitdiff_plain;h=75e51f6ac4a0905a53e1ab68a0547e7fc15caa54;p=lhc%2Fweb%2Fwiklou.git

Added a --backoff option for syncFileBackend.php

* This is useful for avoiding in-progress operations if locking
  is not enabled (the journal is updated before file changes).
