Makemake ʻoe e ʻike pehea e kamaʻilio ai nā polokalamu kamepiula me kekahi? Inā ʻae, i kēia manawa e ʻike ʻoe i kēia ʻatikala ma ka hoʻohana ʻana i nā paipu e kamaʻilio maikaʻi loa! ʻO ke kumu e aʻo ai e pili ana i ke kamaʻilio ʻana o nā papahana ʻo ia ka mea e hoʻomaopopo iā mākou i ka hana ʻana o kā mākou kamepiula a me ka hāʻawi ʻana i ka ʻike.
Kūkākūkā Inter-Process (IPC)
Ma ke kamepiula, ua noʻonoʻo paha ʻoe i ka mea a kekahi mau papahana e kaʻana like me nā papahana ʻē aʻe? Aia ka pane me kahi mea liʻiliʻi i kapa ʻia ʻo inter-process communication, a i ʻole IPC no ka pōkole. Kū ʻo IPC no ke kamaʻilio ma waena o ke kaʻina hana, a he mea like ia me ke ʻano o nā papahana a i ʻole nā kaʻina hana e kamaʻilio pū kekahi me kekahi. Pono nā polokalamu i kahi ala e kaʻana like i nā manaʻo a me nā ʻikepili, e like me ka poʻe e kamaʻilio pū kekahi. ʻO kekahi o nā ala e hoʻokō ai lākou i kēia me nā paipu.
He aha nā paipu?
No laila, he aha ka paipu? Ma kahi laʻana o ka honua maoli, he paipu lōʻihi ka paipu e hiki ai i nā mea e like me ka wai a me ke kinoea ke kahe. A ma ke ʻano o nā kamepiula, hana like ka paipu, akā ma kahi o ka wai, hiki iā ia ke hele i ka ʻikepili. Ua like nā paipu me nā ala, e like me ka mea hoʻohui ma waena o kekahi papahana a me kekahi papahana, no laila hiki ke kamaʻilio maʻalahi nā papahana. E noʻonoʻo a 12mm paipu hdpe e like me ka pahee wai ma kahi paka wai. Hāʻawi ia i ka wai (a i ʻole ka ʻikepili) e paheʻe mālie mai kahi wahi a i kekahi!
No ke aha ka maikaʻi o nā paipu?
ʻO kahi mea maikaʻi e pili ana i nā paipu, ʻo ia ka hana maikaʻi loa. No ka mea 16 paipu hdpe e ʻae i nā polokalamu e heluhelu a kākau i kahi ākea, ʻaʻole nui ka manawa e hoʻouna i ka ʻikepili. ʻO ia ka mea e maikaʻi ai nā paipu no ka kaʻana like ʻana i ka ʻike inā ʻo ka wikiwiki ka mea nui. E noʻonoʻo ʻoe e kali lōʻihi no ka pane ʻana mai o kahi hoaaloha i kāu kikokikona—ʻaʻole ia he mea leʻaleʻa loa! ʻO nā paipu e hoʻokō koke i ke kamaʻilio ʻana.
Pehea e hana ai nā paipu?
No laila pehea ka hana ʻana o nā paipu a i ʻole ka paipu? Hoʻohana nā paipu i kahi pūʻulu alahele e hiki ai i nā papahana ʻelua ke hoʻololi i ka ʻike. Hoʻohana ʻia nā kauoha maʻalahi e hana i kahi paipu. ʻO ka paipu kekahi ʻano faila kūikawā i hoʻohana ʻia e paʻa i ka ʻikepili ma waena o nā papahana ʻelua ke hana ʻia kahi paipu. Kākau kekahi i ka ʻikepili i ka faila, a heluhelu kekahi mai ia mea. ʻO kēia ka mea e hiki ai i nā papahana ʻelua ke kamaʻilio maʻalahi a me ka holomua. Ua like ia me ka pahu leta, me ka waiho ʻana o kekahi kanaka i kahi leka a hele mai kekahi e kiʻi i kēlā me kēia manawa āna e makemake ai.
Ka Pono o na Paipu
a 16mm paipu hdpe pono no nā mea e like me ka hoʻolālā pūnaewele, ʻo ia ka manawa e kamaʻilio ai nā papahana i kekahi i kekahi ma ka pūnaewele. Hāʻawi lākou i nā polokalamu pūnaewele like ʻole e kaʻana wikiwiki i ka ʻike. ʻO lākou nā mea hana papahana kaulana e like me Node. js, hiki i nā paipu ke kamaʻilio me kekahi i kekahi i ka manawa maoli. He ʻano liʻiliʻi ia e hiki ai i kāu mau punahele punahele ma kāu kelepona ke kamaʻilio me kekahi i kekahi e mālama iā ʻoe i ka loop!
