This app renders in a worker thread instead, shares one render across concurrent scrapes that want the same output, and streams the payload back in chunks. ) annotationsN)CallableIteratorMapping) dataclass)MappingProxyType)Final)CollectorRegistry)choose_encoder gzip_accepted)Request)StreamingResponse)ASGIAppReceiveScopeSendir RESPONSE_CHUNK_SIZE_BYTESzContent-Encodinggzip _GZIP_HEADERST)frozenslotsc:eZdZUdZded<ded<ded<ded <y ) ScrapeRequestz]What a scrape asks for, normalized so that header spellings sharing an output share a render.z$Callable[[CollectorRegistry], bytes]encoderstr content_typeboolgzippedtuple[str, ...] metric_namesN)__name__ __module__ __qualname____doc____annotations__u/home/oem/CyberBrain26-unified/.venv/lib/python3.12/site-packages/litellm/integrations/prometheus_metrics_endpoint.pyrrsg 11 M!!r'rcNt|\}}t||t||S)N)rrrr )r rr )acceptaccept_encodingr rrs r(parse_scrape_requestr,(s/*62G\ !o.!  r'c|j|jr|j|jn|}|jrt j |S|SN)rr restricted_registryrrcompress)registryrequestrendereds r( render_scraper42sKoo>E>R>R$$W%9%9:X`H'.oo4== "C8Cr'c(eZdZdZddZddZddZy) CoalescedScrapeRendererzjRenders the registry in a worker thread, sharing one render per distinct output across concurrent scrapes.c2||_ti|_yr.) _registryr _inflight)selfr1s r(__init__z CoalescedScrapeRenderer.__init__<s!FVWYFZr'ct|jjDcic] \}}||us ||c}}|_ycc}}wr.)rr9items)r:finishedkeytasks r(_forgetzCoalescedScrapeRenderer._forget@s:)dnnFZFZF\*ud`dlt`t39*uv*us A A cK|jj|}|tj|d{Stjtj t |j|}ti|j||i|_|j|jtj|d{S77wr.) r9getasyncioshield create_task to_threadr4r8radd_done_callbackrA)r:r2inflightr@s r(renderzCoalescedScrapeRenderer.renderCs..,,W5   11 1))'*;*;M4>>[b*cd)*KT^^*KWd*KL t||,^^D))) 2 *s"6CC BCC CCN)r1r returnNone)r>zasyncio.Task[bytes]rKrL)r2rrKbytes)r!r"r#r$r;rArJr&r'r(r6r69st[w*r'r6cJfdtdttDS)Nc36K|]}||tzywr.)r).0startbodys r( z_chunks..Os xD!:: ; xsr)rangelenr)rRs`r(_chunksrVNs xqRUVZR[]vIw xxr'c*t|dfd }|S)Nc Kt||}t|jjdd|jjddt |j j d}j|d{}tt||j|jrtnd}||||d{y7J7w)Nr*zaccept-encodingzname[])r*r+r ) media_typeheaders) r r,r[rCtuple query_paramsgetlistrJrrVrrr)scopereceivesendr2scraperRresponserenderers r( metrics_appz*make_metrics_asgi_app..metrics_appUs 0,??&&x4#OO//0A2Fw33;;HEF  %OOF33+ DM**%+^^M  ugt,,, 4 -s%BCC AC CCC)r_rr`rrarrKrL)r6)r1rerds @r(make_metrics_asgi_apprfRs-h7H - r')r*rr+rr rrKr)r1r r2rrKrM)rRrMrKzIterator[bytes])r1r rKr)&r$ __future__rrDrcollections.abcrrr dataclassesrtypesrtypingr prometheus_clientr prometheus_client.expositionr r starlette.requestsr starlette.responsesrstarlette.typesrrrrrr%rrr,r4r6rVrfr&r'r(rqs# 77!"/F&199#,5,');V(DE uE $d#""$"D***yr'
