Use the pre-expanded Perl configuration variables.
Conda builds of Perl need these (and a fix to the Perl
config files, see https://github.com/conda/conda/issues/8425
for details).
When using an EPICS 7 softIoc.dbd file with a PV from an older version
of Base which didn't have all the fields, our attempts to read those
fields will time out, but the internal logic was buggy. Don't try to
print the values of timed out fields at all. The user will still see a
warning about connection timeouts at the top.
* recnames:

yet more record name validation
Further record name validation
popFirstTemp() may return NULL

This is needed when convertRelease.pl gets run before the
EPICS::Path and EPICS::Release modules are installed, and
after 'make uninstall' has deleted the lib/perl directory.
Instead of displaying the failures from each submodule at the end
of testing that submodule, RULES_TOP suppresses the output when
it detects a parent module, and RULES_MODULES adds the children's
failure lists into the parent's list so they all get shown at the
end of the tests/results.

If fastReceiver() took more than 0.01 seconds to exit,
sleepySender() might have pushed a second message onto
the queue after setting recvExit, so there would be an
extra message in the queue for the next test, which I
was seeing on Appveyor. That's my current theory...
The internal mySend() and myReceive() routines do expect a timeout
of -1 to mean wait forever, see the epicsMessageQueueSend() and
epicsMessageQueueReceive() API routines.
Move the code that wakes up the next sending task to after we've
added our threadNode to the receiveQueue. He still has to wait for
us to release the Mutex though, so this might make no difference.
This commit also changes when we decrement the number of waiting
senders so it always happens immediately after a threadNode gets
taken off the sendQueue by the code that removed it.
When sending a message, if the queue is full so we have to wait, we
create a threadNode with an eventNode in it and stick it on the
sendQueue, then wait for a receiver to signal that event, waking us.
If we awoke due to a timeout but a receiver was actually waking us
up anyway (i.e. eventSent was set), we shouldn't give up.
Introduced freeEventNode() which ensures eventNodes don't have a
signalled event in them before returning the node to the freeList.
Callers pass the status from epicsEventWaitWithTimeout() to indicate
whether it was signalled or not. If it timed out we must trigger it
and Wait to clear the event state.
It appears that previously a negative timeout actually implemented a
'wait forever', but the VxWorks and RTEMS implementations both check
for (timeout <= 0) and return immediately if nothing can be done
without waiting.

Don't apply the %.tap: %.t and %.xml: %.tap rules to tap and junit
result files from other test frameworks.
(They would overwrite the other frameworks' own rules.)
Use only %.t files in new TESTSCRIPTS.t var for Perl tests.
TAPFILES and JUNITFILES can be appended to by other rules.
The runtests and test-results rules have no direct recipes.
Added run-tap-tests and tap-results rules, simlified recipe.
Make %.tap:%.t and %.xml:%.tap into static pattern rules.
It was created before modern continuous integration systems
came along; Diamond were supposed to run the tests for us,
but they didn't last for very long.
For all standard build ACTIONS, a rule before-<action> is
run just before running that action in the subdirectories
given by the DIRS variable. Only works in Makefiles that

Lists the directories with failed tests at the end of the build.
It is no longer necessary to use 'make -k' to see the results
of all tests after one or more failures as only the top-level
test-results recipe will generate a build error.
- make runtests a double-colon rule, so that other test frameworks
can add their own recipes independently
- only define runtests:: $TESTSCRIPTS rule when there are TESTSCRIPTS
(to avoid having it run every time when no TESTSCRIPTS are defined)
- $(strip $TAPFILES) inside ifneq to fix trouble when TAPFILES=' '
I split his two "Fields Common to ..." sections back into separate docs,
added links between them all, and made the appropriate build changes.
Also added these and the aai/aao records to the documentation index.
Passing zero as to GetProcAddress is undocumented,
but seems to be equivalent to passing GetModuleHandle(NULL)
which searches only the address space of the executable file.
Emulate the effect of dlsym(0, ...) by searching all
loaded modules. Probably not so efficient...
* Use EXPAND_COMMON for architecture-independent templates,
generated in the O.Common directory instead of O.$(T_A).
* Add EXPAND_ME to name Makefile variables to be added without
having to provide a value (permits spaces in value too).
* Comments in RULES_EXPAND describe how to use these rules.
The second increment of refcnt must occur before pthread_create
or a subtle possibility of a double free() occurs if the thread
runs immediately and self-joins before the second inc.
Also use atomic ops for joinable flag to ensure that
concurrent joins will error properly.
Also improve behavior in case signals are delivered to the sleeping
thread. This fixes a potential security weakness reported by codacy
(interaction of usleep with SIGALRM and other timer functions such
as sleep(), alarm(), setitimer(), and nanosleep() is unspecified).
This fix apply to event record device with constant INP.
Now when the event record is proccessed the associated records with the
same SCAN setup get triggered correctly, it is not more necessary to set
VAL on event record.

Working with Dirk Zimoch @dirk.zimoch, fixed various issues
with bit operations on VS2019 32bit. These seem to relate to
handling bit 31 of a 32 bit number.
As EPICS << is an arithmetic bit shift, following Java we
have added <<< and >>> operators for logical shifts
Though it is on a different architecture, this looks like
a similar issue to LP: #1838792
prefer SO_REUSEPORT on targets which define it.
Linux defines both, and seems to treat
SO_REUSEPORT and SO_REUSEADDR as equivalent.
BSD derivatives need SO_REUSEPORT.
taskWait() actually returns OK on timeout, so drop the timeout warning
(the other implementations don't have one).
The taskWait() may return ERROR with S_objLib_OBJ_ID_ERROR if the target
thread has higher priority; this indicates a successful join, because
we already did a rendezvous using joinSem.
Delete joinSem *after* calling taskSpareFieldSet(), in case it matters.
This lets us collect and echo their stderr streams, and if they
hang up without responding we can kill them directly instead of
just giving up and bailing out.
Left debug output turned on for now.
GNU libstdc++ prior to GCC 6.1.0, the overlay math.h always
includes math.h from glibc, which defines isinf() and friends.
GCC 6.1.0 includes a change (6c8ced3f4f867b72a623fe2f23efa204c5786a28)
so that the overlay math.h never includes the glibc math.h
when compiling c++.
The overlay math.h sometimes includes "using std::isinf"
Determined by inspecting libc math.h when building gcc.

Exception specifications are deprecated: http://isocpp.github.io/
CppCoreGuidelines/CppCoreGuidelines.html#e30-dont-use-exception-
specifications . They will be removed from the C++ standard with
C++20. Modern compilers are warning about them since years. Thus
it's unlikely that anyone is still using the epicsThrows() macro.
Even if that's the case the fix is trivial: Simply remove the macro.

sending 0 bytes helps to detect broken connections on some systems (but is undefined behavior on Linux, fails on vxWorks and is a documented no-op on Windows)
cannot print sockets with %d in Windows, they are not small ints but maybe pointers.
ask logClient socket how many bytes are still in the send queue and don't discard them in case the connection turns out broken.
use dynamic debug flag for logClient
increase error message buffer size for long (Windows) error messges
improve logClientShow to show unsent bytes on level 2 (and fix level 1)
removed unneeded include
no need to delay startup only because log server is currently not available
send pending log messages directly after connecting
avoid needless memmove calls
elimitate duplicate code in logClient
do not discard unsent messages when log server has closed connection, instead try to send them after reconnect

This function, and struct iocshFuncDef, expose
internal details. Specifically iocshCmdDef::func .
Which prevents changing/extending the iocsh function
signature.
Deprecate in favor of iocshCmd() and iocshRun().
The BSP routine sysTimeBaseFreq() is optional. If not present or
non-functional we measure the frequency of the CPU's time-base
counter (against the OS system clock) once at initialization-time.
Always release field logs when we drop them.
Adjust how first and after modes work to make them easier to test.
Change stream checking code, fix leaks and double frees.
Add mustStash(), mustSwap(), streamReset(), drop mustPassOld().
Modify test code to check free-list count and release all of
the field-logs returned by the filter; it must release any of
the field-logs that it decides to drop.
Moves where the field-logs get freed into the mustPass/mustDrop routines,
where it only happens if the filter didn't free them itself.
Filters that save field-logs can't use this code as-is.

After configuring the build you should be able to build EPICS base by
issuing the following commands in the distribution's root directory
(base):
gnumake clean uninstall
gnumake
The command "gnumake clean uninstall" will remove all files and
directories generated by a previous build. The command "gnumake" will
build and install everything for the configured host and targets.
It is recommended that you do a "gnumake clean uninstall" at the root
directory of an EPICS directory structure before each complete rebuild
to ensure that all components will be rebuilt.
Example application and extension
A perl tool, makeBaseApp.pl is included in the distribution file. This
script will create a sample application that can be built and then
executed to try out this release of base.
Instructions for building and executing the example IOC application can
be found in the section "Example Application" of Chapter 2, "Getting
Started", in the "IOC Application Developer's Guide" for this release.
The "Example IOC Application" section briefly explains how to create and
build an example application in a user created <top> directory. It also
explains how to run the example application on a vxWorks ioc or as a
process on the host system. By running the example application as a
host-based IOC, you will be able to quickly implement a complete EPICS
system and be able to run channel access clients on the host system.
A perl script, makeBaseExt.pl, is included in the distribution file.
This script will create a sample extension that can be built and
executed. The makeBaseApp.pl and makeBaseExt.pl scripts are installed
into the install location bin/<hostarch> directory during the base
build.
Multiple host platforms
You can build using a single EPICS directory structure on multiple host
systems and for multiple cross target systems. The intermediate and
binary files generated by the build will be created in separate
subdirectories and installed into the appropriate separate host/target
install directories. EPICS executables and perl scripts are installed
into the $(INSTALL_LOCATION)/bin/<arch> directories. Libraries are
installed into $(INSTALL_LOCATION)/lib/<arch>. The default definition
for $(INSTALL_LOCATION) is $(TOP) which is the root directory in the
distribution directory structure, base. Created object files are stored
in O.<arch> source subdirectories, This allows objects for multiple
cross target architectures to be maintained at the same time. To build
EPICS base for a specific host/target combination you must have the
proper host/target C/C++ cross compiler and target header files and the
base/configure/os directory must have the appropriate configure files.
