# Perl + cpanm + the XS build chain + libldap (a runtime dep of libpq 17;
# EV::Pg's XS module dynamically links it for the LDAP authentication path,
# so it must be present even though our tests never authenticate via LDAP).
# ssl-dev is needed by several of the CPAN deps (Net::SSLeay, IO::Socket::SSL,
# etc.).

# Distribution deps. We do NOT use `cpanm --installdeps /src` here on
# purpose: cpanfile pins EV::Pg < 0.03 (the verified line on libpq 15) but
# we deliberately install EV::Pg@0.07 to match the libpq we shipped in
# this image. --installdeps would see the mismatch and try to downgrade.
# Instead we install each dep explicitly at the version we want, and rely
# on cpanm's transitive resolution to pull EV, Future, Moo, SQL::Abstract,
# Test::More, Test::Exception via the dependencies below. See README for
# the cpanfile TODO.
#
# Order matters: install DBIO::PostgreSQL FIRST so its own test deps
# (which include DBD::Pg) never enter cpanm's resolution path for /src.

# explicitly is verbose but makes the image self-contained and survives
# cpanfile changes -- new dependencies added to dbio-postgresql-ev
# are caught by the test run itself (missing-module errors are obvious),
# rather than silently breaking the image build.

# Default: run the whole live test suite. The caller picks the PG instance
# via DBIO_TEST_PG_DSN; tests under t/*-live.t skip themselves when it is
# unset, so the same image is usable for offline lint and online coverage.
#
# EXTRA_LIB_DIR lets the caller mount a directory of in-development Perl
# modules at run time and have it prepended to @INC. The typical case is a
# newer DBIO::PostgreSQL checked out alongside this repo (the version on
# CPAN lags behind and lacks the async_backend hook this distribution's
# live tests rely on). The entrypoint script wires the path into
# PERL5LIB; prove then sees the local checkout first.
