[PATCH 01/11] Don't use EV_CLEAR for kqueue events. 378+ messages / 3 participants [nested] [flat]
* [PATCH 01/11] Don't use EV_CLEAR for kqueue events. @ 2020-02-24 13:53 Thomas Munro <thomas.munro@gmail.com> 0 siblings, 0 replies; 378+ messages in thread From: Thomas Munro @ 2020-02-24 13:53 UTC (permalink / raw) For the semantics to match the epoll implementation, we need a socket to continue to appear readable/writable if you wait multiple times without doing I/O in between (in Linux terminology, level-triggered rather than edge-triggered). Similar to commit 3b790d256f8 for Windows.

* [PATCH] Allow progress tracking of sub-commands. @ 2026-05-04 09:32 Antonin Houska <ah@cybertec.at> 0 siblings, 0 replies; 378+ messages in thread From: Antonin Houska @ 2026-05-04 09:32 UTC (permalink / raw) Some commands that support progress reporting run sub-commands, which also report their progress. The typical case is that REPACK builds indexes. Instead of disabling the progress tracking of the sub-commands, we can allow both the "parent" command and the sub-command to report their progress at the same time. --- contrib/file_fdw/file_fdw.c | 44 +++++++++++ src/backend/commands/indexcmds.c | 10 ++- src/backend/commands/repack.c | 14 +++- src/backend/utils/activity/backend_progress.c | 76 ++++++++++++++++--- src/backend/utils/activity/backend_status.c | 1 + src/backend/utils/adt/pgstatfuncs.c | 9 ++- src/include/utils/backend_status.h | 7 ++ 7 files changed, 142 insertions(+), 19 deletions(-) diff --git a/contrib/file_fdw/file_fdw.c b/contrib/file_fdw/file_fdw.c index 33a37d832ce..a60fb226320 100644 --- a/contrib/file_fdw/file_fdw.c +++ b/contrib/file_fdw/file_fdw.c @@ -36,6 +36,7 @@ #include "optimizer/pathnode.h" #include "optimizer/planmain.h" #include "optimizer/restrictinfo.h" +#include "utils/backend_status.h" #include "utils/acl.h" #include "utils/memutils.h" #include "utils/rel.h" @@ -119,6 +120,16 @@ typedef struct FileFdwExecutionState CopyFromState cstate; /* COPY execution state */ } FileFdwExecutionState; +/* + * Since progress tracking of multiple COPY commands is not supported, the + * first file_fdw node of the plan needs to set pgstat_track_activities to + * false during startup, and the last active node needs to restore the + * original value during shutdown. + */ +static bool save_pgstat_track_activities = false; +static int fdw_nodes = 0; +static int active_fdw_nodes = 0; + /* * SQL functions */ @@ -616,6 +627,12 @@ fileGetForeignPlan(PlannerInfo *root, { Index scan_relid = baserel->relid; + /* + * This seems to be the appropriate place to count file_fdw nodes in the + * plan. + */ + fdw_nodes++; + /* * We have no native ability to evaluate restriction clauses, so we just * put all the scan_clauses into the plan node's qual list for the @@ -695,6 +712,18 @@ fileBeginForeignScan(ForeignScanState *node, int eflags) /* Add any options from the plan (currently only convert_selectively) */ options = list_concat(options, plan->fdw_private); + /* + * Save the value of pgstat_track_activities if this is the first file_fdw + * node of a plan containing multiple file_fdw nodes, and disable the + * progress tracking.
