Subject: lib-index: Don't update log_file_tail_offset on sync if reading dovecot.index.log... 
X-Git-Tag: 2.3.21~62
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=aae93d3ea73004ba1883bbf91c9e40f613ffc857;p=thirdparty%2Fdovecot%2Fcore.git

lib-index: Don't update log_file_tail_offset on sync if reading dovecot.index.log failed

This is more of a theoretical issue, since dovecot.index.log read failure is
very unlikely.
