Nicolas Tsiftes 39ea9405bb Added a function for setting the I/O semantics on a Coffee file descriptor. Changed the configuration parameters slightly and updated the platform definitions to reflect this change. 2011-02-09 15:03:57 +01:00
nvt-se fc34a4572b Removed the deprecated COFFEE_DIR_CACHE_ENTRIES parameter. 2009-09-22 16:31:36 +00:00
nvt-se b0431cc688 removed obsolete offset type definitions. 2009-07-13 20:02:16 +00:00
nvt-se 1e0ca9ceac Made the use of micro logs configurable to make file modifications
more efficient on storage types that support inline updates.

The sky platform uses logs, and the native platform uses no logs.

nvt-se 9b548619ed removed redundant definitions. 2009-02-25 23:57:13 +00:00
nvt-se d0a546b049 A long refactoring session yielded the following.
Technical changes:

* Factored out file specific information from the file descriptor
  structure into a new file structure.

  - Useful file metadata can be stored after the file is closed.
  - File descriptors become much smaller.
  - Significantly reduces the need to scan for the file end.

* Use correct types in all function signatures.
* Removed the directory cache.

Results:

* Enormous speed increase when opening cached files (10x-20x.)
* Multiple fd:s pointing to the same file have the correct semantics.
* About 100 bytes smaller ROM size.
* Slightly smaller static RAM size.

nvt-se 10639bc982 use abstract types for offsets and pages so that we can easily port it to
very large or small memories.
