Fix unchecked buffer allocation in dbChannel.c
Replace calls to epicsStrDup() with checked malloc() for
things that happen often after iocInit.
Michael Davidsaver pointed out this issue.
Merged J. Lewis Muir's fix for comments introduced by macro.
Added fixes to allow comments to be indented too, which used
to work if the '#' was followed by white-space or any argument
separator character.
The handling of comment lines is only performed before macro
expansion, thus lines with macros that expand to comment lines will
not be correctly handled as comment lines.
By chance this kind of worked sometimes because a "#" command that
does nothing is internally added to the command registry to make it
show up in the help output. Relying on this is broken. Furthermore,
if the line starts with '#' followed by a non-separator character
(e.g. "##", "#whatever", etc.) it will not work (i.e. it will produce
a command-not-found error).
This fix checks to see if the first character of the line after macro
expansion is '#'. If it is, it considers the line to be a comment.
Refactored logClientSend in libCom/logClient/logClient.c; took the code between the mutex operations and
moved it to a private method - sendLogMessageinChunks. Call this method once for the prefix (if it exists) and once
for the actual message.
Added ioCsh registration code into src/libCom/iocsh/libComRegister.c registering a command called
"iocLogPrefix" that sets this prefix.
Unit tested with and without prefixes.
Performance tested with and without prefixes - without prefix is approx the same. With prefix is about
twice the time (reflecting the two calls to sendLogMessageinChunks I think)
Build lexer and parser from libCom/Makefile.
Since libCom now includes asLib.c and asLib_lex.c we must build
antelope and flex without linking them to Com. This works because
they only need epicsTempFile anyway. However make doesn't like a
subdirectory with the same name as a target object, so the antelope
source directory is now called yacc. The two main.c files were also
renamed to avoid other build problems.
Merge asHost into Com and remove mentions in CONFIG_BASE
Lots of noise since SRCS must be renamed to Com_SRCS
Each SRC_DIR gets its own Makefile fragment, and where it needs
private build rules a RULES files.
If this pattern gets used elsewhere we could automate the include
lines (search $(SRC_DIRS) for Makefiles and RULES files?).
replaced the osdSysTime provider with a new osiClockTime provider,
stringin device support puts record into alarm if no working provider,
added osdTimeRegister() to RTEMS/osdTime.h.
* Added new monitoring API with insert and remove callbacks; the old API is
still supported though.
* Added report routine, callable from iocsh.
* taskwdInsert() can take a NULL tid, meaning the calling thread.
