2019-10-08 Jens Hauke <hauke@par-tec.com> - 5.4.1-1
* Workaround: TCP reconnect, if a call to connect() do not progress.
New environment variables:
PSP_RECONNECT_TIMEOUT timeout in ms before reconnecting after an
error
PSP_CONNECT_STALLED max number of reconnect timeouts before
reconnecting even without an error on the
connection.
2019-09-19 Jens Hauke <hauke@par-tec.com> - 5.4.0-1

runtime.
2019-07-09 Jens Hauke <hauke@par-tec.com> - 5.3.1-1

* Workaround: PSM2: Segfaults in psm2_ep_disconnect() and
psm2_mq_ipeek(): Wait at least PSP_PSM_CLOSE_DELAY milliseconds
after the last call to psm2_mq_send() before calling
psm2_ep_disconnect().

1,"us" "ssss.uuuuuu" seconds and microseconds since pscom_init
"date" "YYYY-MM-DD_hh:mm:ss.uuuuuu" in localtime
"wall" "ssss.uuuuuu" seconds and microseconds since the Epoch
"delta" "ssss.uuuuuu" seconds and microseconds since last log
2019-03-19 Simon Pickartz <pickartz@par-tec.com>

PSP_DEBUG=1 fatal conditions + errors (default)
PSP_DEBUG=2 + warnings
PSP_DEBUG=3 + information
PSP_DEBUG=4 + debug
PSP_DEBUG=5 + verbose debug
PSP_DEBUG=6 + tracing calls
In addition, some logging aspects might be raised:
PSP_DEBUG_VERSION=1 Show the pscom version (info)
PSP_DEBUG_CONTYPE=1 Show connection types (was PSP_DEBUG>=1, now
PSP_DEBUG>=3 (info) or PSP_DEBUG_CONTYPE=1)
PSP_DEBUG_SUSPEND=1 or 2 Show suspend info/debug
PSP_DEBUG_PRECON=1 Trace pre-connection handshake (trace)
PSP_DEBUG_STATS=1 Show statistics at exit
PSP_DEBUG_REQ=1 Track pscom requests (this adds latency
for additional req bookkeeping!)

a peer (Before it was an abort with "Assertion failed")
* Enhancement: UCP: pscom4ucp: non-blocking receives from libucp.
