具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
需要说明的是，本公开所涉及的用户信息(包括但不限于用户设备信息、用户个人信息等)和数据(包括但不限于用于分析的数据、存储的数据、展示的数据等)，均为经用户授权或者经过各方充分授权的信息和数据，并且相关数据的收集、使用和处理需要遵守相关国家和地区的相关法律法规和标准，并提供有相应的操作入口，供用户选择授权或者拒绝。
下面对本公开实施例的应用场景进行解释：
本公开实施例提供的输入法程序运行方法，可以应用于调用输入法程序进行信息输入的场景。具体地，本公开实施例提供的方法，可以应用于终端设备，图1为本公开实施例提供的一种输入法程序的执行过程示意图，如图1所示，终端设备的磁盘空间(硬盘)内存储有输入法程序的词库文件，终端设备在启动输入法程序后，会将磁盘中的词库文件中的词库数据拷贝至内存中的内核空间，之后，建立用户空间与磁盘空间的映射关系，当执行输入法程序的输入功能而需要使用词库数据时，通过页表从内核空间中获得与词库文件相对应的词库数据，即以文件映射的方式加载词库数据。之后响应于用户指令，利用词库数据完成输入功能的执行，例如实现拼写、组成、纠错 等输入法程序的输入功能。
相关技术中，针对上述以文件映射方式加载词库数据的技术方案，在词库数据被拷贝至内核空间后，利用内核空间能够实现数据高速缓存的特性，可以实现词库数据的快速调取，但另一方面，由于内核空间被所有进程所共享，当输入法程序处于后台闲置状态时，操作系统会对内核空间的资源进行回收，导致存储在内核空间(物理内存)中的词库数据被清楚。当输入法程序再次被调起而执行输入功能时，输入法程序(对应的线程)通过已建立映射的虚拟地址访问物理页上的词库数据，此时，由于虚拟地址访问对应物理页上缺少词库数据，导致中央处理器(CPU)的内存管理单元发出中断指令，即出现缺页中断。在出现缺页中断时，操作系统需要从磁盘上重新读取词库文件而获得词库数据，并重新拷贝至内核空间后，再基于内核空间中的词库数据，执行后续的输入功能，该过程导致词库数据的调用耗时增加，进而影响输入法程序的运行流畅度和稳定性。本公开实施例提供一种输入法程序运行方法以解决上述问题。
词库数据通常需要预先加载至内存中，以供输入法程序进行调用，然而，相关技术中加载至内存中的词库数据，会在内存资源紧张的情况下被操作系统清空，导致词库调用的耗时增加的问题，进而影响输入法程序的运行流畅度和稳定性。
参考图2，图2为本公开实施例提供的输入法程序运行方法的流程示意图一。本实施例的方法可以应用在终端设备中，该输入法程序运行方法包括：
步骤S101：在执行输入法程序的输入功能前，获取执行输入功能所需的词库数据对应的虚拟地址。
示例性地，参考图1所示的输入法程序的执行过程示意图，在输入法程序运行后、执行输入功能前，获取词库数据对应的虚拟地址，其中，虚拟地址是表征词库数据的数据位置的信息，输入法程序通过虚拟地址来获取到词库数据，并利用词库数据执行后续的输入功能，例如，例如词库数据进行组词、词语纠错等。其中，虚拟地址位于虚拟地址空间内，虚拟地址空间也称为进程地址空间，是操作系统内核中的一个数据结构，是由进程(例如输入法程序进程)的虚地址构成的地址空间，虚拟地址空间和进程地址空间为本领域技术人员知晓的技术概念，词库数据对应的虚拟地址，由输入法程序的 具体运行情况决定的，词库数据对应的虚拟地址可以通过调用具体的虚拟地址查询函数得到，为本领域技术人员知晓的相关技术，以上内容为此不再一一举例赘述。
进一步地，输入法程序的输入功能，是指输入法程序通过接收用户输入的输入信息(例如键盘信息、语音信息等)，生成文字、数字、标识等内容信息的功能，即输入法程序的主体功能，输入功能是一种前台运行功能，即在执行输入法功能时，输入法程序需要运行于系统前台，即处于调起状态；与之相对的，输入法程序还可以包括更新功能、推送功能等可以运行于系统后台、无需调起即可执行的非主体功能，其中，与更新功能、推送功能等非主体功能不同的时，输入功能的实现需要词库数据的支持，输入法程序需要基于词库数据，将用户输入的输入信息转换成对应的文字、数字，并按需要进行显示，以实现基本的文字输入功能。因此，在一种可能的实现方式中，获取执行输入功能所需的词库数据对应的虚拟地址的时机，可以是输入法程序被调起至前台运行时。示例性地，如图3所示，步骤S101的具体实现方式包括：
步骤S1011：对处于后台运行的输入法程序进行实时检测；
步骤S1012：当检测到输入法程序被调起至前台运行时，获取执行输入功能所需的词库数据对应的虚拟地址。
示例性地，在输入法程序启动后，在不进行文字输入的情况下，输入法程序在系统后台运行，一种更具体地实现方式中，在操作系统运行后，输入法程序启动并常驻在系统后台运行，当需要进行文字输入时，例如用户点选可网页、软件中的编辑文本栏(edit_text)，操作系统将输入法程序从后台调起至前台运行，并显示输入法程序的输入界面。图4为本公开实施例提供的一种获取词库数据的虚拟地址的过程示意图，参考图4所示，终端设备(例如为智能手机)运行浏览器程序时，当接收到用户针对地址栏的点选操作后，调起输入法程序，并显示输入法程序的输入界面，与此同时，终端设备(输入法程序)在检测到输入界面被调起并显示后，获取词库数据的虚拟地址，之后，之后基于词库数据的虚拟地址，将词库数据加载至内核空间。再之后，用户可进一步通过操作该输入法程序的输入界面，输入键盘信息，例如单击“GHI”键，输入法程序利用词库数据执行输入功能(组词功能)，在输入法 界面内显示包含有“h”字母的词语，例如图中所示的“hi”、“happy”、“http”等。其中，该词库数据的虚拟地址在输入法程序启动后是已知的预设信息，可以直接读取该预设的词库数据的虚拟地址，具体过程不再赘述。
步骤S102：将词库数据加载至虚拟地址对应的内核空间。
示例性地，在得到词库数据对应的虚拟地址后，在一种可能的情况下，若内核空间中已存储有上述词库数据，则终端设备基于该虚拟地址，可以直接获得上述词库数据，之后利用词库数据完成组词、纠错等输入功能。此种可能的情况通常是在输入法程序处于前台运行的情况下，操作系统不会对处于调起状态的应用程序所使用的内存数据进行清理和回收，因此可以直接基于虚拟地址获得对应的词库数据。而在另一种可能的情况下，若内核空间中未存储有上述词库数据，则终端设备基于该虚拟地址，无法在内核空间中直接获得上述词库数据，进而会导致缺页中断(也称为硬缺页中断、硬中断、硬错误)。此种情况下，终端设备从磁盘中获取上述词库数据，并加载至虚拟地址对应的内核空间中，此时由于输入法程序还未开始执行输入功能，即未调用词库数据，相当于实现了对词库数据的预载入，从而避免在后续步骤中，当需要使用调用词库数据来执行输入功能时产生的缺页中断问题。
进一步地，示例性地，虚拟地址包括存储词库数据的至少一个词库文件所对应的虚拟内存页地址，虚拟内存页地址与词库文件的磁盘地址一一映射，如图5所示，示例性地，步骤S102的具体实现方式包括：
步骤S1021：针对至少一个词库文件对应的虚拟内存页地址进行遍历，确定词库文件中所存储的缺失数据，其中，缺失数据为未被拷贝至内核空间的词库数据。
步骤S1022：将词库文件中所存储的缺失数据加载至内核空间。
示例性地，执行输入功能所需要的词库数据，以词库文件的形式存储在磁盘中，之后基于用户空间与磁盘空间的映射关系，使输入法程序获得执行输入功能所需的词库数据，即以文件映射的方式加载词库数据。其中，词库文件的磁盘地址与虚拟内存页地址对应，虚拟内存页地址是指虚拟内存所对应的虚拟内存页的地址，虚拟内存是一种将硬盘空间作为内存来使用的相关技术，此处不再赘述，而虚拟内存页地址是用于描述上述虚拟内存页的连续地址位置的信息，由于虚拟内存页是被虚拟出来的，因此其对应的虚拟内存 页地址也是虚拟的，与实际的物理内存页的地址并不统一。
进一步地，正常情况下(内存数据未被操作系统清理)，通过虚拟内存页地址可以从内核空间中的相应位置获得词库文件中存储的词库数据，因此，终端设备通过遍历虚拟内存页地址，即依次访问各虚拟内存页地址，根据操作系统返回的访问结果，可以确定对应的内核空间中，是否包含有响应的词库数据，例如，若操作系统返回的访问结果为大于0小于或等于127之间的整型，则确定该虚拟内存页地址对应的词库文件中存储的数据为正常的词库数据；若操作系统返回的访问结果为0，或者Null，则确定该虚拟内存页地址对应的词库文件中存储的数据为缺失数据。其中，缺失数据为未被拷贝至内核空间的词库数据。
进一步地，若词库文件中所存储的数据为缺失数据，则基于预设的页表获取该词库文件(虚拟内存页地址)对应的磁盘地址，并从磁盘地址读取词库数据，拷贝至内核空间，实现将词库文件中所存储的缺失数据加载至内核空间。最终，使执行输入功能所需的词库数据均加载至虚拟地址对应的内核空间，避免后续出现的缺页中断问题。
其中，示例性地，本实施例所提供的方法，可以应用于linux系统，或者基于linux系统的操作系统中，具体地，在针对每一词库文件对应的虚拟内存页地址进行遍历时，利用linux内核的文件预读取机制，对文件页对应的虚拟内存页地址进行遍历，以将至少两个连续的文件页中的数据加载至内核空间，其中，词库文件由至少两个文件页构成，每一文件页用于存储一部分词库数据，通过上述方式，利用linux内核的文件预读取机制可以高效的预读文件的优点，提高词库数据加载至内核空间的速度。
步骤S103：响应于用户指令，调用内核空间中的目标词库数据，以执行输入法程序中用户指令所对应的输入功能。
示例性地，进一步地，在将执行输入功能所需的词库数据均加载至虚拟地址对应的内核空间后，响应于用于触发输入功能的用户指令，从内核空间中调用用于执行用户指令所触发的输入功能的目标词库数据，来实现用户指令所对应的输入功能。其中，词库数据可以是包含有具体的函数、方法和数据的功能模型，其具有对应的调用接口(API)，通过调用接口来实现对词库数据的调用，从而实现词库数据的词库功能，进而根据一个或多个词库数据 的词库功能的集合，实现对应的输入功能。图6为本公开实施例提供的一种执行输入功能的过程示意图，如图6所示，示例性地，用户指令comm_1中包括键盘信息字母“z”和字母“m”(图中示为comm_1[z,m])，用户指令comm_1用于指示输入法程序基于上述键盘信息来生成对应的词组。终端设备(输入法程序)根据上述用户指令comm_1，调用内核空间中的词库数据pack_1和词库数据pack_3作为目标词库数据，来对用户指令comm_1进行处理，其中，词库数据pack_1用于将键盘信息作为首字母进行组词，生成汉字词语；词库数据pack_3用于根据键盘信息对汉字词语进行纠错，得到常用汉字词语。最终将常用汉字词语显示在终端设备的显示界面上，输入功能执行完毕。
在本实施例中，通过在执行输入法程序的输入功能前，获取执行输入功能所需的词库数据对应的虚拟地址；将词库数据加载至虚拟地址对应的内核空间；响应于用户指令，调用内核空间中的目标词库数据，以执行输入法程序中用户指令所对应的输入功能。通过在执行输入法程序的输入功能前，获取虚拟地址，并基于虚拟地址预加载词库数据，从而在响应用户指令执行输入功能时，可以直接从内核空间以文件映射的方式获得对应的目标词库数据，避免了由于内存清空而引发的硬缺页中断的问题，降低输入法程序调用词库数据的整体耗时，减少卡顿，提高输入法程序的输入功能的稳定性和运行流畅度。
参考图7，图7为本公开实施例提供的输入法程序运行方法的流程示意图二。本实施例在图2所示实施例的基础上，对步骤S102进一步细化，该输入法程序运行方法包括：
步骤S201：在执行输入法程序的输入功能前，获取执行输入功能所需的词库数据对应的虚拟地址，虚拟地址包括存储词库数据的至少一个词库文件所对应的虚拟内存页地址，虚拟内存页地址与词库文件的磁盘地址一一映射。
步骤S202：基于当前的词库文件的虚拟内存页地址，访问内核空间的页高速缓存区，得到访问结果。
示例性地，页高速缓存区是内存中用于存储部分磁盘数据的区域，通过页高速缓存区，可以实现允许操作系统把通常存放在磁盘上的一些数据保留在内存的内核区域中，以便于在需要访问磁盘时，可以从页高速缓存区获取 相应的数据，而无需从磁盘读取数据，从而提高数据读写速度。使用文件映射的方式加载输入法程序所使用的词库文件的场景下，各词库文件均对应一个虚拟内存页地址，虚拟内存页地址在图2所示实施例中已进行详细介绍，此处不再赘述。针对每一词库文件进行循环遍历，依次获取每一词库文件的虚拟内存页地址，具体地，这一次具体的循环过程中，基于当前的词库文件的虚拟内存页地址，可以得到该虚拟内存页地址所对应的页高速缓存区的地址，也即页高速缓存区内存储虚拟内存页地址对应的词库数据的地址，进而对每一虚拟内存页地址所对应的页高速缓存区的地址进行访问，得到的访问结果即该地址处的数据。
其中，在一种可能的实现方式中，词库文件对应至少两个位于页高速缓存区的物理页，物理页用于存储词库数据；虚拟内存页地址包括至少两个子内存页地址，子内存页地址表征物理页的首地址。如图8所示，步骤S202的具体实现方式包括：
步骤S2021：根据当前的词库文件的至少两个子内存页地址，遍历对应的物理页。
步骤S2022：依次读取每一物理页的首字节，得到访问结果。
示例性地，页高速缓存区由物理页构成，虚拟内存页地址由至少两个子内存页地址构成，物理页的位置与子内存页地址一一对应，即通过子内存页地址映射至物理页。在遍历各词库文件的过程中，针对每一词库文件，分别基于对应的子内存页地址，访问对应的物理页，并读取每一物理页的首字节，并根据读取的首字节的内容，得到访问结果。
步骤S203：根据访问结果，确定当前的词库文件对应的缺失数据，其中，缺失数据为未被拷贝至内核空间的词库数据。
示例性地，步骤S203的具体实现方式包括：若词库文件对应的第一物理页的首字节为非预设信息，则将第一物理页所存储的数据，确定为缺失数据。
图9为本公开实施例提供的一种确定缺失数据的过程示意图，如图9所示，示例性地，针对词库文件File_1的过程，词库文件File_1对应多个物理页，例如图中所示的物理页p1、物理页p2、物理页p3等。根据子内存页地址，分别读取物理页p1的首字节、物理页p2的首字节、物理页p3的首字节，分别得到物理页p1的首字节的内容为[01000100]；物理页p2的首字节的内容 为[01100101]；物理页p3的首字节的内容为[00000000]；其中，[00000000]为非预设信息，因此，在读取物理页p3的首字节后，将物理页p3确定为第一物理页，物理页p3所存储的数据，确定为缺失数据。之后，从磁盘空间中获取该物理页p3对应的词库数据(缺失数据)，并加载至内核空间，完成输入法程序所需的词库数据的补全。
本实施例中，通过将词库文件映射为多个物理页，并基于对物理页的首字节的访问结果，确对应的物理页是否为缺失数据，实现了对词库文件中所保存的词库数据的分段加载、快速判断。有效提高了确定缺失数据的确定速度，从而降低了遍历全部词库文件所需的耗时，提高词库数据的加载效率。
步骤S204：基于当前的词库文件的磁盘地址，将对应的缺失数据加载至页高速缓存区。
示例性地，在得到缺失数据后，从磁盘中获取缺失数据对应的物理页，并加载至内核空间，完成输入法程序所需的词库数据的补全。如图10所示，步骤S204的具体实现方式包括：
步骤S2041：根据第一物理页对应的子内存页地址，获得对应的第一磁盘地址。
步骤S2042：读取第一磁盘地址处的数据，得到缺失数据，并将缺失数据加载至第一物理页。
示例性地，第一物理页即存储缺失数据的物理页，基于上述步骤，在根据物理页的首字节确定出第一物理页后，根据第一物理页对应的子内存页地址，获得对应的第一磁盘地址，内存页地址和磁盘地址之间的映射关系通过预设的页表确定。其中，词库文件包括至少两个文件页，文件页用于存储词库数据，第一磁盘地址是词库文件的文件页的首地址。即高速缓存页中的物理页和磁盘中构成词库文件的文件页是一一对应的关系。文件页是对词库文件进行分割的结果，物理页是文件页加载至内存后的数据对象，磁盘地址是文件页的地址，第一磁盘地址即第一物理页对应的第一文件页的地址。因此，获得内存页地址对应的第一磁盘地址后，读取第一磁盘地址处的数据，即第一文件页，第一文件页中保持的数据，即缺失数据。之后，将第一文件页中的确实数据，加载至页高速缓存区中的第一物理页，完成将缺失数据加载至页高速缓存区的过程。
步骤S205：若当前的词库文件为最后一个词库文件，则执行步骤S206；否则，定位至下一个词库文件，并返回步骤S202。
进一步地，在处理完当前的词库文件后，若当前词库文件为输入法程序配置的所有词库文件的非最后一个词库文件，在继续定位至下一个词库文件，并返回步骤S202循环执行上述步骤对词库文件进行处理，以使输入功能对应的缺失数据能够被加载至内存中待用；若该词库文件为输入法程序配置的所有词库文件的最后一个词库文件，则说明所有词库文件均已处理完毕，此时，可以保证所有词库文件中存储的词库数据已被全部加载至内存中待用，此种情况下可以避免出现缺页中断的问题，因此可以结束循环，执行后续输入功能调用的步骤。
步骤S206：响应于用户指令，调用内核空间中的目标词库数据，以执行输入法程序中用户指令所对应的输入功能。
在本实施例中，步骤S201和步骤S206与图2所示实施例中的步骤S101、步骤S103的一致，详细论述请参考步骤图2所示实施例中内容，这里不再赘述。
