The __STDC_VERSION__ >= 199901L test never succeeds
in C++, and there were issues with the epicsInt8
definition anyway (int8_t is signed, but char might
not be).
I also removed the epicsBoolean enum which we never use.
When testing the msi program, don't rely on EPICS_HOST_ARCH
to find the binary executable as we may be running the tests
on a cross-arch such as linux-x86-debug.
Using the m_ prefix to denote class data members is dangerous in
code that has to compile on VxWorks 5.5 (which 3.15 does) because
the net/mbuf.h header contains the following macro definitions:
#define m_next mBlkHdr.mNext
#define m_len mBlkHdr.mLen
#define m_data mBlkHdr.mData
#define m_type mBlkHdr.mType
#define m_flags mBlkHdr.mFlags
#define m_nextpkt mBlkHdr.mNextPkt
#define m_act m_nextpkt
#define m_pkthdr mBlkPktHdr
#define m_ext pClBlk
#define m_extBuf m_ext->clNode.pClBuf
#define m_extFreeRtn m_ext->pClFreeRtn
#define m_extSize m_ext->clSize
#define m_extRefCnt m_ext->clRefCnt
#define m_extArg1 m_ext->clFreeArg1
#define m_extArg2 m_ext->clFreeArg2
#define m_extArg3 m_ext->clFreeArg3
#define m_copy(m, o, l) m_copym((m), (o), (l), M_DONTWAIT)
#define m_copym(m, o, l, w) netMblkChainDup(_pNetDpool, (m), (o), (l), (w))
#define m_freem(m) netMblkClChainFree(m)
#define m_free(m) netMblkClFree(m)
#define m_mbufs mNum
#define m_drops mDrops
#define m_wait mWait
#define m_drain mDrain
#define m_mtypes mTypes
While the names in the original change all appear to be safe, I
don't want us to start using this convention because we will then
have to police commits more closely or risk build failures in the
future when someone who doesn't know about or remember the issue
can't or doesn't try building their code against VxWorks 5.5.
I don't particularly like the this-> convention to mark member
names either, but until the VxWorks 5.5 support requirement goes
away the m_ convention is worse. Another common convention of
using a leading underscore is not safe either, those names are
reserved for the C/C++ implementation.
dbPutString() now has two behaviors. If link_type==CONSTANT
and constantStr==NULL, the link has not yet been initialized.
Just set the ->text field.
If the link has been initialized, then use dbSetLink() to
make the assignment.
Eliminate special handling for DBF_DEVICE.
This structure holds the processed form of any link type.
It is populated by dbParseLink(), which can be called w/o
record locking.
dbCanSetLink() checks the the parsed link, and a DBLINK field
have compatible types for assignment.
Record locking is required, but this does not modify the field.
dbSetLink() makes the actual assignment.
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.
