Don't check for preprocessor symbols from system header files in port
include files, since those header files aren't included at this point.
included, and then include <strings.h> if so. Several systems already
needed <strings.h> anyway. Some new systems that claim to conform to the
Unix 9x "standard" do not declare str[n]casemp() in string.h, and C99
compilers will not like that.
equivalent.
In linux.h there were some #undef HAVE_INT_TIMEZONE, which are useless
because HAVE_TM_ZONE overrides it anyway, and messing with configure
results isn't cool.
all platforms, not just SCO. The operation is undefined for Unix-domain
sockets anyway. It seems SCO is not the only platform that complains
instead of treating the call as a no-op.
eliminating some wildly inconsistent coding in various parts of the
system. I set MAXPGPATH = 1024 in config.h.in. If anyone is really
convinced that there ought to be a configure-time test to set the
value, go right ahead ... but I think it's a waste of time.
Making PQrequestCancel safe to call in a signal handler turned out to be
much easier than I feared. So here are the diffs.
Some notes:
* I modified the postmaster's packet "iodone" callback interface to allow
the callback routine to return a continue-or-drop-connection return
code; this was necessary to allow the connection to be closed after
receiving a Cancel, rather than proceeding to launch a new backend...
Being a neatnik, I also made the iodone proc have a typechecked
parameter list.
* I deleted all code I could find that had to do with OOB.
* I made some edits to ensure that all signals mentioned in the code
are referred to symbolically not by numbers ("SIGUSR2" not "2").
I think Bruce may have already done at least some of the same edits;
I hope that merging these patches is not too painful.
