commit 2bad6aef10339f000f7cb578108db5ee80bd640c
Author: Mark Goodwin <mgoodwin@redhat.com>
Date: Wed Jun 9 17:04:33 2021 +1000
pmproxy: add mutex for client req lists, fix https/tls support, QA
Add a new mutext to struct proxy and use it to protect parallel
multithreaded updates to the proxy->first client list.
Also use the same mutext to protect updates to the pending_writes
client list and avoid the doubly linked list corruption that was
causing parallel https/tls requests to get stuck spinning in
flush_secure_module(), as reported in BZ#1947989.
qa/1457 is extensively updated to test parallel http, https/tls
(and combinations of http and https/tls) RESTAPI calls. Previously
it only tested a single https/tls call.
With these changes, parallel https/tls RESTAPI requests from the
grafana-pcp datasource to pmproxy now work correctly whereas previously
pmproxy would hang/spin.
Resolves: RHBZ#1947989 - pmproxy hangs and consume 100% cpu if the
redis datasource is configured with TLS.

libpcp_web: add mutex to struct webgroup protecting the context dict
Add a mutex to the local webgroups structure in libpcp_web and
use it to protect multithreaded parallel updates (dictAdd,
dictDelete) to the groups->contexts dict and the dict traversal
in the timer driven garbage collector.
Tested by qa/297 and related tests and also an updated version
of qa/1457 (which now stress tests parallel http and https/tls
pmproxy RESTAPI calls .. in a later commit).
Related: RHBZ#1947989

src/libpcp: be more careful when calling __pmLogChangeVol()
Mark observed a SEGV which looks like __pmLogFetch() died because
ctxp->c_archctl->ac_mfp was (unexpectedly) NULL.
See: https://github.com/performancecopilot/pcp/issues/1338
Initial guess is that a physical file was removed by concurrent
activity (like pmlogger_check or pmlogger_daily), causing
__pmLogChangeVol() to fail ... and this was not being checked for
on the __pmLogFetch() path and in a couple of other places.

commit 49bdfdfff83ac165de2bdc9a40e61a56512585d8
Author: Ken McDonell <kenj@kenj.id.au>
Date: Sun Jul 4 10:07:09 2021 +1000
libpcp: redefine __pmLogSetTime()
The problem is that if physical files for the data volumes of an
archive are removed (asynchronously by someone else) while we're
trying to switch volumes then we don't handle this safely.
The previous commit 10763319 was as stop-gap to address Mark's SEGV
issue at https://github.com/performancecopilot/pcp/issues/1338 and
simply handled direct calls to __pmLogChangeVol() and ensured the
return status was checked.
I was aware, then Coverity made a lot more people aware, that this
"fix" was incomplete, specifically the calls to __pmLogChangeVol()
from within __pmLogSetTime() were not checked.
To fix the latter we have to change the type of __pmLogSetTime() from
void to int so we can return status to indicate that __pmLogChangeVol()
has failed. And then make sure all the callers of __pmLogSetTime()
check the status returned from that function.

libpcp_web: plug mem leak in redisMapInsert during daily log-rolling
When pmlogger_daily processes daily archives, the resulting
merged archive(s) are discovered and processed by pmproxy
(if the discovery module is enabled). Since the metadata and
logvol data in each merged archive is likely to have already
been previously processed (but discovery doesn't know this),
we see a lot of dict updates for existing keys and values that
are already mapped.
Static analysis by Coverity (CID323605 Resource Leak) shows
when redisMapInsert calls dictAdd for an existing key, the
new value field is assigned but the old value is not free'd,
and so it leaks.

libpcp_web/discovery: improve lock handling and scalability
Rework the global log-rolling lock detection with finer grain
(per-pmlogger directory) detection, and break early in
process_meta() and process_logvol() if a lock file is found
in the same directory as a monitored archive. This is much
more scalable since archive directories that are not locked
can continue to be processed and ingested whilst log-rolling
progresses elsewhere. Also uses much less CPU time since we
don't need a traversal of all monitored archives looking for
locks on every fs change event.
Also improve process_logvol/meta handling for archives that
are deleted whilst being processed by the discovery module.
In conjunction with Kenj's changes in libpcp - stop processing
metadata and logvols if pmFetchArchive returns -ENOENT .. the
archive has been deleted so there is no point further ingesting
it's data.
