Peter Eisentraut d56cb42b54 Activate perlcritic InputOutput::RequireCheckedSyscalls and fix resulting warnings This checks that certain I/O-related Perl functions properly check their return value. Some parts of the PostgreSQL code had been a bit sloppy about that. The new perlcritic warnings are fixed here. I didn't design any beautiful error messages, mostly just used "or die $!", which mostly matches existing code, and also this is developer-level code, so having the system error plus source code reference should be ok. Initially, we only activate this check for a subset of what the perlcritic check would warn about. The effective list is chmod flock open read rename seek symlink system The initial set of functions is picked because most existing code already checked the return value of those, so any omissions are probably unintended, or because it seems important for test correctness. The actual perlcritic configuration is written as an exclude list. That seems better so that we are clear on what we are currently not checking. Maybe future patches want to investigate checking some of the other functions. (In principle, we might eventually want to check all of them, but since this is test and build support code, not production code, there are probably some reasonable compromises to be made.)

README

src/pl/plperl/README

PL/Perl allows you to write PostgreSQL functions and procedures in
Perl.  To include PL/Perl in the build use './configure --with-perl'.
To build from this directory use 'make all; make install'.  libperl
must have been built as a shared library, which is usually not the
case in standard installations.

Consult the PostgreSQL User's Guide for more information.
