Second life viewer portable7/2/2023 LLLFS - the "Local File System" procedures, used to directly read and write to the local OS storage.The LLVFile is a general procedure for accessing both of them. LLVFile - the purpose of this code is still unclear (to Scalar Tardis / Dale Mahalko) but this appears to be how the two different VFS are accessed.It's only about 8 megabytes, but why does it have to be fully loaded in a virtual RAM-disk all the time using limited system memory? May be worthwhile to replace this with direct on-disk storage, perhaps in a ZIP file. This contains the graphical elements and sounds of the Second Life user interface. gStaticVFS - a read-only VFS in "static_data.db2" and "static_index.db2".This needs to be removed and replaced with direct filesystem calls to folder-based storage. It is the primary limitation for allowing unlimited local asset caching in the viewer as currently designed. gVFS - the "general VFS" which is used for temporary storage for assets, in a private RAM-disk held in memory at all times."VFS" is not used in the code alone, and so is usually referring to comments in the source, or debugging/logging notes. h file is found it is listed here below the. This listing duplicates the layout and format of the Viewer Source Files page, providing a direct 1-to-1 correspondence with each section and source file. The following list of source references is based on viewer source released 1.19.1.4 in the SVN repository, and will need future updating as the viewer source continues to evolve: And as the Wikipedia article for the APR states, if an OS doesn't directly support some needed feature, the APR will directly implement that feature itself, making it very useful to replace as many legacy calls with APR calls. Local file storage based purely on the APR may be faster and more stable than previous methods created in-house by Linden Lab, and would make the client much easier to port to more widely varying OS platforms since the APR is already widely deployed across many platforms. There is no official stated policy anywhere, but it would appear there is an effort to replace the LFS calls with APR calls, and perhaps eventually, also replacing VFS calls with APR calls. As I explored the code further I noted the related file access procedures of the LFS and then discovered the use of the Apache Portable Runtime used to replace the LFS. 36 Unlisted in Viewer Source Files pageįrom Scalar Tardis / Dale Mahalko: This started out as a list of references in the client source to the keyword VFS, which then became more useful in table format when I noticed the gVFS and gStaticVFS.31 User Interface - Menus, Overlays, Login.30 User Interface - Import, Export, Upload.28 User Interface - Objects and Edit Tools.25 User Interface - Data:Money and Land. 22 User Interface - Chat, Instant Messaging, Notices, Reports.17 Data and Communication - Region and World.
