Modern browser can not discharge and safety after long-time use well in order to solve browser resourceProperty problem, great majority have all used multi-process model. But user's computer hardware resource is limited,In order to allow browser can have the body that surfs the web preferably to test under the configuration of different user computer hardware,So need the quantity of the process that limiting browser opens, prevent thrashing in similar operations systemPhenomenon occur. This has just produced the multiplexing model of browser process.
The Chrome(full name of for example Google: GoogleChrome is developed by Google aWeb browsing instrument) browser, Window on the World browser etc. be all to have used multi-process model. Exist simultaneouslyMixed model for user in the time that browser is browsed the Web page, distributes (playing up) process of specifically working orThread.
In realizing, the Chrome of Google browser uses multi-process model. This model produces clear at browserWhen the device support of looking at expansion decompress(ion), installation, use the independently progress of work; Need wash with watercolours at browser browsing pageWhile dying, according to the page need security permission used independently play up process carry out content of pages parsing andPlay up; In the time expanding and expand required plug-in component operation, for the expansion and the plug-in unit that need different rights useIndependently expansion or plug-in unit process; Browser is also for the internal pages of browser prompts information has been distributed differenceProcess.
Because primary of Google's Chrome browser supports that Webkit(WebKit is apple MacOSXThe title of system engine framework version, is mainly used in Safari, Dashboard, Mail and some otherMacOSX program kernel), so browse and do not support Webkit to need in other words IE (Trident) user(IE:InternetExplorer, internet survey meter; Trident, is called again MSHTML, is InternetThe title of the typesetting engine of Explorer) when the page rendering of interior nuclear properties, user just can not use GoogleChrome browser is browsed. Now the multiplexing model of the process of Google is also no longer applicable. Exist on the other handSecure Model Design (being mainly sandbox design) in the Chrome of Google self is pacified with the system that IE kernel needsMay there is conflict in full powers limits, may cause directly using the multiplexing model of process of Chrome can not be fineGround, or even can not normally represent the Web page.

According to this method, the maximum process number of preset browsing device side is 3; Initiate webpage in browser sideThe browse request of www.gmail.com is determined in chrome browser in described multiple browser kernelsCore is the first browser kernel that adaptation is played up this requested webpage www.gmail.com; Judge current existingProcess number 3 has reached described maximum process number 3; The process 310 in described existing process that finds is usedThe process that chrome browser kernel is played up; The authority of the process 310 finding described in examining with beatOpen the required authority of described webpage consistent; Page thread in the consistent described process 310 of rights of usingThe concrete steps of opening described webpage are as follows:
Open described webpage with the page thread in process 310. Can select following proposal:
Scheme 1: if the kernel that described the first browser kernel is Chrome browser, in the described right to useLimit in the each thread in the thread pool of consistent process the browse request of webpage is ranked, one by one etc.Treat that the thread that transfers idle condition to by busy state in described thread pool opens described webpage.
For example in process 310, there are 3 page threads 311 ~ 313, clear by described www.gmail.comLook at request and the queuing of browse request at it after, if now thread 311 enters idle condition, with thisIdle thread 311 responds the browsing page request in described queue.
Scheme 2: the each thread in the thread pool of the consistent process of described rights of using is all in busy shapeWhen state, notify browser host process to search other existing browser process, determine in another browserCore type and authority with open the required browser kernel type of described new web page and authority consistent have intoJourney, opens described webpage.
For example in process 310, there are 3 page threads 311 ~ 313, and just all locate busy state, notify clearThe device host process 300 of looking at is searched other existing browser process, determines another browser kernel type and power(for example, limit the existing process consistent with opening the required browser kernel type of described new web page and authorityProcess 320), open described www.gmail.com webpage.
Another kind of situation is, if described the first browser kernel is Trident (IE) kernel, described in findingThere is the process that in process, process 310 is used Trident (IE) kernel to play up; Can select to adopt such scheme2 open webpage, but can not adopt such scheme 1 to open webpage, and can select to adopt following proposal 3 to openWebpage:
Scheme 3: if described the first browser kernel is IE kernel, and each thread in described process is all locatedIn busy state, newly-built thread in described process, opens described webpage, and beats in described new threadAfter opening described webpage, in the time being closed, destroy again described this newly-built thread.
Each thread 311 ~ 313 of for example process 310 is in busy state, newly-built line in process 310Journey 314, opens described www.gmail.com webpage, and after described www.gmail.com is closed,Destroy described newly-built thread 314.
Another kind of situation is, no matter described the first browser kernel why type, described in examine and findWhether required with the opening described webpage consistent step of authority of authority of process, further comprise: examineTo the each thread in the browser process being searched all in busy state; The master of notice browser entersWhether required with opening described webpage the authority of other processes that journey finds described in going to examine authority be consistentAnd in described process, have the thread in idle condition, so as the authority of browser process with open described inIn consistent other browser process of the required authority of webpage, open described webpage.
For example, verification process 310, process 320 are all the first browser kernel, 310 authority with openThe requested permissions of webpage www.gmail.com is consistent, and each thread of further examining process 310 is all locatedIn busy state; Notice browser host process 300 is gone the authority of verification process 320 and opens webpageWhether www.gmail.com requested permissions available free thread whether in consistent and process 320, if so,Use process 320 is opened described www.gmail.com webpage.

If must use Trident kernel, carrying outAfter step 502, execution step 523 ~ step 530; If must use Webkit kernel, in execution stepAfter 502, execution step 503 ~ step 510;
Step 502: judge the maximum process number of suitable browser according to user's hardware system;
Step 503: according to abovementioned steps, if judgement must be used Webkit kernel, start to perform step 503 ~Step 510. Judge whether current existing browser process number has reached the maximum process number of described browser; AsThe described existing process number of fruit has reached described maximum process number, execution step 504; If not, execution step510；
Step 504: enumerate the process of playing up that uses Webkit kernel; What is called is enumerated, searches one by one,When the process of playing up that finds to use Webkit kernel, carry out subsequent step 505;
Step 505: the process of playing up that judges whether to have enumerated all use Webkit kernels; If enumeratedThe process of playing up of complete all use Webkit kernels, performs step 510; If not, perform step 506;
Step 506: the authority of examining this process; Examine the use Webkit kernel that finds play up intoThe authority of journey;
Step 507: whether the authority of examining this process required permission match with opening described new web page; IfDo not mate, go to step 504 processes of playing up of enumerating another and use Webkit kernel; If coupling,Execution step 508;
Step 508: whether the Thread Count of examining this process has reached maximum allowed line number of passes; If; ?Go to step 504 processes of playing up of enumerating another and use Webkit kernel; If not, execution step 509;
