Ukuhlolwa kwe-proxy ye-Python: kungani i-Future.cancel() ishiya ama-thread egijima
Qonda ukuthi kungani ukukhansela ama-future alindile kungayeki ukuhlolwa kwenethiwekhi okusebenzayo, futhi unciphise umjaho we-proxy ngaphandle kokuthi ubonisa impilo yendawo.
I-worker eyodwa ithola i-proxy esebenzisekayo. Ubuyisela ikheli layo, ushayela i-cancel kwamanye ama-future, futhi ulindela ukuthi umsebenzi wenethiwekhi uyeke. Kungenzeka ungayeki.
I-Future ingakhanselwa ngaphambi kokuba i-callable yayo iqale. Uma i-thread isivele yenza isicelo, ukukhansela i-Future yayo akukuvimbi lokho kusebenza kwe-socket. I-worker idinga umsebenzi wayo wenethiwekhi onomkhawulo kanye nendlela yokuhlanza.
Isikhathi sokuphila kwe-executor naso sibalulekile. Ukuphuma esimweni se-ThreadPoolExecutor kulinda ukuthi umsebenzi wayo uqede. Ukuthola umphumela owodwa osheshayo bese ulinda ama-worker amaningi anensa kungenza ukubambezeleka okuphelele komfoni kubukeke ngokuphelele ngendlela ehlukile kune-latency ebikiwe yomnqobi.
Nciphisa umjaho ngaphambi kokuba uqale
- Nciphisa inani lokuhlolwa ngesikhathi esisodwa esikhundleni sokuhambisa uhlu lomphakathi olungenamkhawulo. Uhlu lwe-proxy lwamahhala lunikeza abazoba yingxenye yokufaka komhloli, kuyilapho iphrothokholi ye-endpoint ngayinye igcinelwa i-worker.
- Nikeza isicelo ngasinye inqubomgomo efanele yokuxhumana nokufunda.
- Nikeza umfoni isabelomali sesinqumo sisonke.
- Chaza ukuthi ubani okhipha noma ovala imiphumela evela kuma-worker aphila isikhathi eside kunesinqumo.
Ukulinda isikhathi esincane kwi-Future akufani nokwenza isicelo sayo esiyisisekelo sibe sifushane. Ngokufanayo, ukushiya umphumela akukhululi zonke izinsiza zenethiwekhi ngokushesha.
Umphumela wokuqala ophumelelayo nawo uwukuhlolwa kokuqala okuphumelelayo kuphela. Kungase kuncike ekuhleleni, kokuxhumana okugciniwe, kanye nendawo ethile yokuhlola. Akubonisi ukuthi i-endpoint iyona eshesha kunazo zonke emhlabeni noma ukuthi umsebenzi wangempela uzophumelela.
Ngokuvamile ichibi elincane eligciniwe elinemibono yakamuva lilula kunokugijima nalo lonke uhlu ngaphambi kokulanda ngakunye. Sebenzisa umphumela wokusebenza kwangempela ukubuyekeza irekhodi, kanye nenqubomgomo yokubuyisela elawulwayo yokwehluleka. Ukuhlolwa kwangaphambili kufanele kuzuze izindleko zako esikhundleni sokuphinda kabili umsebenzi ngamunye ngomkhuba.
