sneak	ebdecf9aba	Default max_concurrent_processing to half the CPUs pixa sees (closes #242) ... The default was one image per CPU Go uses, and a container with no CPU limit sees every CPU of the host. It is now half of runtime.GOMAXPROCS(0), rounded down and at least 1, from imageprocessor.DefaultMaxConcurrentProcessing, which both the config and imageprocessor.New use. The two existing tests of the default expect the new one, as the owner allowed on the issue. "Running under upaas" gives the worst-case memory, with a per-image peak of about 1.6 GiB measured on pixad for an 8192x8192 source in each output format, and tells the operator to set PIXA_MAX_CONCURRENT_PROCESSING and PIXA_UPSTREAM_CONNECTIONS to fit the container's memory.

sneak	de7ecfdb5e	Test that max_concurrent_processing defaults to half the CPUs ... An omitted max_concurrent_processing, and New given none, must be half the CPUs Go uses, rounded down, and at least 1. The tests set GOMAXPROCS to 1, 2, 3 and 8 and fail until the default changes (#242). Model: opus-5-5	2026-10-15 20:41:02 +00:00
clawbot	00da62db2c	Exit with the shutdown's code and wait for image processing (closes #86) ... fx alone handles SIGINT and SIGTERM; the server's own handler, which only cancelled a context that fx's stop did not wait for, is gone. fx's Run exits with the shutdown's code: the one a shutdown request carries, 0 for a signal, 1 when the app fails to start or stop. A listen error asks fx to shut down with exit code 1. A Sentry DSN that cannot be used fails the server's start hook, so fx stops what had already started. The server's stop hook stops the HTTP server, then waits for the images still being processed, both within ShutdownTimeout; images still being processed after that are logged and fail the stop, so the exit code is 1.

clawbot	baf457d21e	Bound concurrent image processing and upstream fetches (closes #64) ... Nothing bounded total in-flight work, so a burst of cache misses across hosts could exhaust memory. Two settings now do: max_concurrent_processing (default the CPUs Go uses) and upstream_connections (default 64, beside the per-host limit). A request that finds either full waits up to 10 seconds, then gets 503; a slot is released on every path. No request holds source bytes while it waits: a cached source is read only after the processing slot is taken, and a fetched one only while it holds its upstream connection. libvips runs one worker thread per image with its operation cache off. Both waits count toward downstream_timeout, as the README says. Model: opus-5-5	2026-09-29 10:32:16 +02:00
