From d17e706063a2a0bb137492efeb7725f8e5d3ab64 Mon Sep 17 00:00:00 2001 From: Dimitri Fontaine Date: Thu, 9 Jul 2026 18:47:37 +0200 Subject: [PATCH 01/14] tests: add pgaftest .pgaf spec suite and CI workflow Introduces the full pgaftest test suite under tests/tap/ and the GitHub Actions workflow that runs it. Depends on the pgaftest binary (#1137). ## tests/tap/specs/ 32 .pgaf specs covering the complete test matrix previously expressed as Python/nosetests files. Each spec encodes topology (cluster{}), setup/teardown, and an ordered step sequence. Single-node / basic: basic_operation, basic_operation_listen_flag, create_run (via ensure), create_standby_with_pgdata, config_get_set, skip_pg_hba, auth, enable_ssl, ssl_cert, ssl_self_signed, ensure, maintenance_and_drop Monitor: monitor_disabled, replace_monitor, extension_update, installcheck Multi-standby: multi_standbys, multi_alternate, multi_async, multi_maintenance, multi_ifdown Citus: basic_citus_operation, nonha_citus_operation, citus_multi_standbys, citus_cluster_name, citus_force_failover, citus_skip_pg_hba Platform / upgrade: debian_clusters, tablespaces, upgrade ## tests/tap/schedule Lists all specs in the run order used by the CI matrix. ## tests/tap/README.md Documents the .pgaf DSL, how to run specs locally with pgaftest, and how to add new specs. ## .github/workflows/run-pgaftest.yml Builds the pgaftest Docker image once (FROM Dockerfile pgaftest target), then fans out one job per entry in tests/tap/schedule in parallel. Each job mounts the spec file, runs pgaftest run, and reports TAP. --- .github/workflows/run-pgaftest.yml | 358 ++++++++++++++++ Dockerfile | 39 ++ tests/tap/README.md | 217 ++++++++++ tests/tap/schedule | 36 ++ tests/tap/schedules/citus-1.sch | 4 + tests/tap/schedules/citus-2.sch | 4 + tests/tap/schedules/multi-alternate.sch | 2 + tests/tap/schedules/multi-async.sch | 2 + tests/tap/schedules/multi-misc.sch | 5 + tests/tap/schedules/node.sch | 11 + tests/tap/schedules/quick.sch | 5 + tests/tap/schedules/ssl.sch | 4 + tests/tap/specs/auth.pgaf | 76 ++++ tests/tap/specs/basic_citus_operation.pgaf | 132 ++++++ tests/tap/specs/basic_operation.pgaf | 402 ++++++++++++++++++ .../specs/basic_operation_listen_flag.pgaf | 117 +++++ tests/tap/specs/citus_cluster_name.pgaf | 120 ++++++ tests/tap/specs/citus_force_failover.pgaf | 86 ++++ tests/tap/specs/citus_multi_standbys.pgaf | 176 ++++++++ tests/tap/specs/citus_skip_pg_hba.pgaf | 124 ++++++ tests/tap/specs/config_get_set.pgaf | 48 +++ .../tap/specs/create_standby_with_pgdata.pgaf | 80 ++++ tests/tap/specs/debian_clusters.pgaf | 51 +++ tests/tap/specs/enable_ssl.pgaf | 84 ++++ tests/tap/specs/ensure.pgaf | 69 +++ tests/tap/specs/extension_update.pgaf | 37 ++ tests/tap/specs/installcheck.pgaf | 46 ++ tests/tap/specs/maintenance_and_drop.pgaf | 75 ++++ tests/tap/specs/monitor_disabled.pgaf | 98 +++++ tests/tap/specs/multi_alternate.pgaf | 267 ++++++++++++ tests/tap/specs/multi_async.pgaf | 251 +++++++++++ tests/tap/specs/multi_ifdown.pgaf | 178 ++++++++ tests/tap/specs/multi_maintenance.pgaf | 278 ++++++++++++ tests/tap/specs/multi_standbys.pgaf | 303 +++++++++++++ tests/tap/specs/nonha_citus_operation.pgaf | 104 +++++ tests/tap/specs/replace_monitor.pgaf | 95 +++++ tests/tap/specs/skip_pg_hba.pgaf | 58 +++ tests/tap/specs/ssl_cert.pgaf | 85 ++++ tests/tap/specs/ssl_self_signed.pgaf | 76 ++++ tests/tap/specs/tablespaces.pgaf | 148 +++++++ tests/tap/specs/upgrade.pgaf | 189 ++++++++ 41 files changed, 4540 insertions(+) create mode 100644 .github/workflows/run-pgaftest.yml create mode 100644 tests/tap/README.md create mode 100644 tests/tap/schedule create mode 100644 tests/tap/schedules/citus-1.sch create mode 100644 tests/tap/schedules/citus-2.sch create mode 100644 tests/tap/schedules/multi-alternate.sch create mode 100644 tests/tap/schedules/multi-async.sch create mode 100644 tests/tap/schedules/multi-misc.sch create mode 100644 tests/tap/schedules/node.sch create mode 100644 tests/tap/schedules/quick.sch create mode 100644 tests/tap/schedules/ssl.sch create mode 100644 tests/tap/specs/auth.pgaf create mode 100644 tests/tap/specs/basic_citus_operation.pgaf create mode 100644 tests/tap/specs/basic_operation.pgaf create mode 100644 tests/tap/specs/basic_operation_listen_flag.pgaf create mode 100644 tests/tap/specs/citus_cluster_name.pgaf create mode 100644 tests/tap/specs/citus_force_failover.pgaf create mode 100644 tests/tap/specs/citus_multi_standbys.pgaf create mode 100644 tests/tap/specs/citus_skip_pg_hba.pgaf create mode 100644 tests/tap/specs/config_get_set.pgaf create mode 100644 tests/tap/specs/create_standby_with_pgdata.pgaf create mode 100644 tests/tap/specs/debian_clusters.pgaf create mode 100644 tests/tap/specs/enable_ssl.pgaf create mode 100644 tests/tap/specs/ensure.pgaf create mode 100644 tests/tap/specs/extension_update.pgaf create mode 100644 tests/tap/specs/installcheck.pgaf create mode 100644 tests/tap/specs/maintenance_and_drop.pgaf create mode 100644 tests/tap/specs/monitor_disabled.pgaf create mode 100644 tests/tap/specs/multi_alternate.pgaf create mode 100644 tests/tap/specs/multi_async.pgaf create mode 100644 tests/tap/specs/multi_ifdown.pgaf create mode 100644 tests/tap/specs/multi_maintenance.pgaf create mode 100644 tests/tap/specs/multi_standbys.pgaf create mode 100644 tests/tap/specs/nonha_citus_operation.pgaf create mode 100644 tests/tap/specs/replace_monitor.pgaf create mode 100644 tests/tap/specs/skip_pg_hba.pgaf create mode 100644 tests/tap/specs/ssl_cert.pgaf create mode 100644 tests/tap/specs/ssl_self_signed.pgaf create mode 100644 tests/tap/specs/tablespaces.pgaf create mode 100644 tests/tap/specs/upgrade.pgaf diff --git a/.github/workflows/run-pgaftest.yml b/.github/workflows/run-pgaftest.yml new file mode 100644 index 000000000..b6a9085c8 --- /dev/null +++ b/.github/workflows/run-pgaftest.yml @@ -0,0 +1,358 @@ +name: pgaftest + +on: + push: + branches: + - main + pull_request: + branches: + - main + workflow_dispatch: + +# One run per branch;

Fix: delegate to keeper_cli_keeper_setup_getopts (after stripping --timeout and --read-write) so that PGDATA is picked up from the environment. Also port the richer implementation from pgaftest-infra: config-file appearance wait, shared deadline, and --read-write phase. 2. tests/upgrade/Makefile: add pgaf-next / pgaf-current targets The CI workflow runs make -C tests/upgrade pgaf-next / pgaf-current but the old Makefile had no such targets (only build / up / down etc). Replace with the new Makefile that auto-detects PREV_TAG from git tags and defaults.h, and add the companion files it needs: Dockerfile.current, pg_autoctl_shim.sh, install-extension.sh. --- src/bin/pg_autoctl/cli_do_misc.c | 245 ++++++++++++++++++++++------- tests/upgrade/Dockerfile.current | 81 ++++++++++ tests/upgrade/Makefile | 158 ++++++++++++------- tests/upgrade/install-extension.sh | 14 ++ tests/upgrade/pg_autoctl_shim.sh | 95 +++++++++++ 5 files changed, 479 insertions(+), 114 deletions(-) create mode 100644 tests/upgrade/Dockerfile.current create mode 100755 tests/upgrade/install-extension.sh create mode 100755 tests/upgrade/pg_autoctl_shim.sh diff --git a/src/bin/pg_autoctl/cli_do_misc.c b/src/bin/pg_autoctl/cli_do_misc.c index 377e7f75f..e39dfaeca 100644 --- a/src/bin/pg_autoctl/cli_do_misc.c +++ b/src/bin/pg_autoctl/cli_do_misc.c @@ -12,6 +12,7 @@ #include #include #include +#include #include #include "postgres_fe.h" @@ -322,109 +323,155 @@ keeper_cli_pgsetup_is_ready(int argc, char **argv) } -/* timeout parsed by keeper_cli_pgsetup_wait_getopts, consumed by wait_until_ready */ -static int pgsetup_wait_timeout = 30; +/* Options specific to "pg_autoctl inspect pgsetup wait" */ +static bool pgsetupWaitReadWrite = false; +static int pgsetupWaitTimeout = 30; /* - * keeper_cli_pgsetup_wait_getopts parses --pgdata and --timeout for the - * "pgsetup wait" subcommand. + * keeper_cli_pgsetup_wait_getopts parses options specific to + * "pg_autoctl inspect pgsetup wait": --read-write, --timeout, plus the + * standard Postgres connection options inherited from the keeper setup. */ int keeper_cli_pgsetup_wait_getopts(int argc, char **argv) { - int c, option_index = 0; - - static struct option long_options[] = { - { "pgdata", required_argument, NULL, 'D' }, - { "timeout", required_argument, NULL, 't' }, - { "version", no_argument, NULL, 'V' }, - { "verbose", no_argument, NULL, 'v' }, - { "quiet", no_argument, NULL, 'q' }, - { "help", no_argument, NULL, 'h' }, + /* + * cli_common_keeper_getopts (called by keeper_cli_keeper_setup_getopts) + * exits with BAD_ARGS when it encounters unknown options.

PASSWORD call after CREATE EXTENSION. - Restore the post-init formation-creation loop in service_monitor_init_start() that calls monitor_create_formation() for each --formation argument. Spec fixes (version-agnostic paths, transient-state races): - debian_clusters.pgaf: use ${PGDATA}/postgresql.conf instead of hardcoded /var/lib/postgresql/17/main/postgresql.conf so PG14-16 CI jobs pass. - config_get_set.pgaf: expect /bin/pg_ctl (substring) instead of full /usr/lib/postgresql/17/bin/pg_ctl path; also sync ssl.sslmode test from reference branch. - ensure.pgaf, multi_alternate.pgaf: skip waiting for the transient 'demoted' state (sub-second, races on loaded CI runners); wait for the stable secondary+primary end state with a 300s timeout instead. - multi_ifdown.pgaf: replace the unreliable test_014_secondary_reports_lsn (compose stop + network connect + blocking perform failover) with the reference design: stop node3+node1 cleanly, reconnect node2, non-blocking failover, wait for node2 at report_lsn. Add test_015_start_node3_node1 step so node2 can pg_rewind missing WAL from the survivors. --- src/bin/pg_autoctl/cli_create_node.c | 28 +++++++++++++++++- src/bin/pg_autoctl/cli_drop_node.c | 13 ++++++++ src/bin/pg_autoctl/monitor_config.h | 7 +++++ src/bin/pg_autoctl/monitor_pg_init.c | 20 ++++++++++++- src/bin/pg_autoctl/monitor_pg_init.h | 3 +- src/bin/pg_autoctl/service_monitor_init.c | 24 ++++++++++++++- tests/tap/specs/config_get_set.pgaf | 8 ++--- tests/tap/specs/debian_clusters.pgaf | 4 +-- tests/tap/specs/ensure.pgaf | 5 ++-- tests/tap/specs/multi_alternate.pgaf | 6 ++-- tests/tap/specs/multi_ifdown.pgaf | 36 +++++++++++------------ 11 files changed, 122 insertions(+), 32 deletions(-) diff --git a/src/bin/pg_autoctl/cli_create_node.c b/src/bin/pg_autoctl/cli_create_node.c index 8ef2e8643..d3aab231a 100644 --- a/src/bin/pg_autoctl/cli_create_node.c +++ b/src/bin/pg_autoctl/cli_create_node.c @@ -793,6 +793,8 @@ cli_create_monitor_getopts(int argc, char **argv) { "listen", required_argument, NULL, 'l' }, { "auth", required_argument, NULL, 'A' }, { "skip-pg-hba", no_argument, NULL, 'S' }, + { "autoctl-node-password", required_argument, NULL, 'W' }, + { "formation", required_argument, NULL, 'f' }, { "version", no_argument, NULL, 'V' }, { "verbose", no_argument, NULL, 'v' }, { "quiet", no_argument, NULL, 'q' }, @@ -821,7 +823,7 @@ cli_create_monitor_getopts(int argc, char **argv) optind = 0; - while ((c = getopt_long(argc, argv, "C:D:p:n:l:A:SVvqhxNs", + while ((c = getopt_long(argc, argv, "C:D:p:n:l:A:SW:f:VvqhxsN", long_options, &option_index)) != -1) { switch (c) @@ -898,6 +900,30 @@ cli_create_monitor_getopts(int argc, char **argv) break; } + case 'W': + { + strlcpy(options.autoctl_node_password, optarg, + sizeof(options.autoctl_node_password)); + log_trace("--autoctl-node-password ****"); + break; + } + + case 'f': + { + /* --formation (may be repeated) */ + if (options.formationCount >= MONITOR_MAX_FORMATIONS) + { + log_error("Too many --formation options (max %d)", + MONITOR_MAX_FORMATIONS); + errors++; + break; + } + int fi = options.formationCount++; + strlcpy(options.formationNames[fi], optarg, NAMEDATALEN); + log_trace("--formation %s", optarg); + break; + } + case 'V': { /* keeper_cli_print_version prints version and exits. */ diff --git a/src/bin/pg_autoctl/cli_drop_node.c b/src/bin/pg_autoctl/cli_drop_node.c index a16e52a6f..6d4b2d717 100644 --- a/src/bin/pg_autoctl/cli_drop_node.c +++ b/src/bin/pg_autoctl/cli_drop_node.c @@ -605,6 +605,19 @@ cli_drop_local_node(KeeperConfig *config, bool dropAndDestroy) (void) cli_drop_node_from_monitor(config, &nodeId, &groupId); } + /* + * With --no-wait the caller takes responsibility for waiting until the + * supervisor has stopped (e.g. via `docker compose wait` in a container + * environment).

Restores all spec, C-source, and build-file differences that had drifted since the branch was split: Spec fixes (transient-state races, version-agnostic paths, test redesigns): - basic_operation.pgaf: wait for stable end state around demote_timeout; use 'assert stays primary while { stop postgres monitor }' pattern; longer CI-safe timeouts - auth.pgaf, enable_ssl.pgaf, ssl_cert.pgaf, upgrade.pgaf: minor alignment - citus_skip_pg_hba.pgaf: coord0a no longer deferred; use 'pg_autoctl override pgsetup hba-lan'; rewritten test sequence - monitor_disabled.pgaf: inline JSON via shell printf instead of /etc/pgaf/specs/*.json bind-mount; remove companion JSON files - multi_async.pgaf: reorder node4 disconnect around LSN election - multi_maintenance.pgaf, multi_standbys.pgaf: remove redundant intermediate waits; adjust timeouts to match reference C source (functional): - cli_common.c: --monitor-password mapped to no-op 'w'; --replication-password to 'e'; matches option letters expected by pg_autoctl node run - cli_create_node.c: remove --monitor-password / --replication-password from cli_create_postgres_getopts (handled via node.ini, not CLI) - cli_do_misc.c, cli_do_root.c/.h: restore reference implementation of 'pg_autoctl inspect/override pgsetup' sub-commands - cli_drop_node.c: restore dropNoWait bool (reference style) - cli_root.c, config.c, coordinator.c, demoapp.c, fsm.c, keeper.c, keeper_config.c/.h, keeper_pg_init.c, monitor.c, monitor_config.c, nodespec.c/.h, primary_standby.c, state.c, watch.c: variable renames, comment updates, and minor refactors aligned to reference -

Inter-command drain must not run before wait commands. runner_exec_step drained the libpq notify buffer before EVERY command using NULL mark arrays. When a wait command (CMD_WAIT_STATE, CMD_WAIT_STATES, CMD_WAIT_MULTI) followed an exec that triggered state transitions, the convergence notifications were consumed without '*' marks, then the wait's own initial drain found nothing left — the '*' prefix was silently dropped. Skip the inter-command drain when the upcoming command is a wait. Each wait command already opens with its own drain that passes the correct mark arrays, so the '*' prefix is applied where it belongs. 2. Suppress pg_autoctl's own log output from stop/start postgres. CMD_STOP_POSTGRES and CMD_START_POSTGRES called 'docker compose exec' without -T and without output redirection, so pg_autoctl's internal log lines (with their own timestamp/PID) appeared on stdout interleaved with pgaftest's output.

The previous code looped while wait_socket(200ms) returned true, so it exited on the first 200ms window of silence. The race: - drain (after subprocess): consumes wait_primary→primary (no *) - post-success loop: wait_socket(200ms) returns false (socket quiet) - return true - primary→primary arrives 50ms later → consumed by [03-03] inter-drain without marks The new helper loops until either ALL listenSatisfied[i] flags are set (every expected convergence NOTIFY has arrived and been marked) or 1 second has elapsed. This means the flush continues as long as there are still outstanding NOTIFYs to collect, and only exits early when the socket is quiet AND all conditions are already marked.

If compose stop node1 fires while node1 is in wait_primary the monitor does not trigger a failover, and the step hangs until timeout. 2. Wait for node2=wait_primary (not primary) before restarting node1. node2 reaches 'wait_primary' (point of no return) once the monitor has committed to promoting it, but it cannot reach 'primary' while node1 is stopped — it needs a synchronous standby to acknowledge WAL.
