| 02:47 | Enhance the extension loading mechanism so that the same source code can be used for run-time loadable extensions and statically linked extensions, and to mask architectural differences in shared libraries. (check-in: a85b6ece user: drh tags: trunk) | |
| 01:23 | Make the SQLITE_EXTENSION_INIT1 and SQLITE_EXTENSION_INIT2 macros into no-ops if the extension is statically linked. (Closed-Leaf check-in: 86eb3eed user: drh tags: loadext) | |

| 22:56 | Experiments in making loadable extensions easier to program. The shared library filename tries various operating-system specific extensions if the bare library name does not work. And the entry point is derived from the filename is the legacy entry point name "sqlite3_extension_init" is not found. (check-in: 6cfa1d73 user: drh tags: loadext) | |

| 20:08 | Expand scope of the SQLITE_MAX_MMAP_SIZE define for the Win32 VFS. (check-in: f4b8faab user: mistachkin tags: trunk) | |
| 17:03 | Refactoring the mmap interface. The controlling pragma is now "mmap_size" instead of "mmap_limit". Also change SQLITE_CONFIG_MMAP_LIMIT and SQLITE_FCNTL_MMAP_LIMIT to SQLITE_CONFIG_MMAP_SIZE and SQLITE_FCNTL_MMAP_SIZE, respecctively. The default mmap_size is now always 0, meaning that memory mapped I/O is off by default. There is a new compile-time option SQLITE_MAX_MMAP_SIZE that determines a hard upper bound on the mmap_size. Setting SQLITE_MAX_MMAP_SIZE to zero disables the memory-mapped I/O logic and causes it to be omitted from the build. An extra argument is added to SQLITE_CONFIG_MMAP_SIZE that can optionally lower the SQLITE_MAX_MMAP_SIZE at start-time. The SQLITE_MAX_MMAP_SIZE is zero for platforms where we know that it does not work, meaning that it cannot be turned on by mistake on those platforms. (check-in: ea1404a1 user: drh tags: trunk) | |
