Rsyslog 8.19.0 (v8-stable) 发布

Rsyslog 8.19.0 (v8-stable) 发布了，Rsyslog 是一个 syslogd 的多线程增强版。

改进记录：

– omelasticsearch: add option to permit unsigned certs (experimentally)
This adds plumbing as suggested by Joerg Heinemann and Radu Gheorghe,
but is otherwise untested. Chances are good it works. If you use it,
please let us know your experience and most importantly any bug
reports you may have.

– imrelp: better error codes on unvailablity of TLS options
Most importantly, we will tell the user in clear words if specific TLS
options are not available due to too-old GnuTLS.

– default stack size for inputs has been explicitely set to 4MiB
for most platforms, this means a reduction from the default of 10MiB, hower
it may mean an increas for micro-libc’s (some may have as low as 80KiB by
default).
– testbench: We are now using libfaketime instead of faketime command line
tool. Make sure you have installed the library and not just the binary!
– refactor stringbuf
* use only a single string buffer
