Michael Davidsaver 504665bf09 iocInit: move dbCaShutdown earlier 
Switch dbCaShutdown from an exit hook to
be called from iocShutdown.  Place it
after callback shutdown.
 2015-07-21 19:08:07 -04:00
Michael DavidsaverandAndrew Johnson fefe6fd1fc Fix shutdown issues with scan and callback. 
The main reason for this merge proposal is the change to "public" API functions.

Use atomic counter to resolve data race on threadsRunning in callback.

Split up callbackShutdown() and scanShutdown() into two phases *Stop() and
*Cleanup(). The *Stop() functions signal worker threads, and wait for them to
exit. The *Cleanup() functions actually reclaim global resources.

These two mechanisms have couplings which are quite complex. I/O Intr scans
involve both scan lists and callbacks.

Michael Davidsaver 93149071b7 dbNotify: shutdown with exitDatabase 
Can't cleanup dbNotify while rsrv or scan tasks
are running as there may be operations in progress.

Michael Davidsaver 9c2a62ea96 dbChannel: shutdown from exitDatabase() 
Can't cleanup dbChannel while rsrv or scan tasks
remain running.

Michael Davidsaver d35780888a iocInit: only teardown from iocBuildIsolated() 
iocShutdown() should only stop threads and cleanup
if the IOC was started with iocBuildIsolated().
If iocBuild() is used then only close CA links
as was done previously.

This is needed as some device support calls epicsExit()
(while holding a record lock).  This make it impossible
to run the full iocShutdown without deadlocking
in scan/callback shutdown, or segfaulting
in doFreeRecord() or dbLockCleanupRecords()

Michael Davidsaver 40838579af iocShutdown: cleanup links 2014-07-31 16:22:01 -04:00
Michael Davidsaver 9f53417a8d add dbCaLinkInitIsolated() 
Initialize dbCa workList lock so that CA_LINK
creation in test code doesn't crash.
Once created links will never connect.

clean up workList for unittest when dbCaShutdown
is called state is already exit.

alarm severity when they are undefined.
Sets initial severity at iocInit too.

Andrew Johnson cb797ca0cd Merged the remove-epicsShareAPI branch. 
Most APIs in libCom are still marked with this,
it's not clear if removing them will be a problem or not.

Andrew Johnson 64c9d7a32a Many tweaks to build on Windows. 
There might be some more to come since I'm not committing
this from my Win32 system.

  * Created separate routines for DB_LINK processing
  * Added dbinitLink() and dbAddLink()
  * Started a Link Support Entry Table, not used yet
  * Everything should still work as before...

Combine recIoc and softDevIoc libraries into dbRecStd

Move base.dbd from ioc/misc/ to std/softIoc/

Andrew Johnson f7d02cc2a8 Convert INST_IO links to regular PV_LINK types, for VDCT support. 
Added new PN_LINK type in link.h, make dbStaticLib display it.
Made all device support extended so links can be changed at runtime.
Modified startup so add_record() always called before regular link processing.
Incomplete, stilll need to add MS/MSS/MSI support, currently disabled.
