Fabian 0e16983dd3 Handle case when wasm table is full (fixes #35) 
Also fix jit_empty_cache when callbacks are pending (fixes #53)

This is also a preparation for setting WASM_TABLE_SIZE to a low value to
work around memory limitations in browsers.

Ernest Wong d6bfa143ed Filestorage: Don't rely on errors to select type of storage 2020-08-30 19:37:15 -05:00
Ernest Wong 83b283ebbe Filestorage: Replace the two server classes with a wrapper class 
Simplifies both the filestorage.js code as well as the starter.js code
that uses these FileStorage classes.

Now, the ServerFileStorageWrapper decorates the other FileStorage
classes by loading from the server when the file is not available.

Moreover, the previous starter.js was incorrectly passing the `baseurl`
parameter (it was passing it when baseurl was not defined nor needed).

Ernest Wong c2dcb440dd Filestorage: Refactor fallback and load-from-server 
Fallback logic is moved to the caller's responsibility.

Empty FileStorages and FileStorages that load from the server are
separated into different classes. This is to avoid faults where the
caller of the constructor forgets to pass in a `baseurl` parameter and
leads to some confusing bug.

Ernest Wong a0c984dc8d Filesystem: Introduce IndexedDBFileStorage 
Uses MemoryFileStorage as a fallback when:
- v86 is used in a browserless environment, e.g. NodeJS
- browser doesn't support indexedDB
- opening indexedDB fails
- existing database is a newer version
- existing database is an old version and is under use - blocking
current v86 instance to connect to it.

Ernest Wong 595d6dca55 Filesystem: Refactor inodedata accesses to async methods 
The "// jshint ignore:line" comments are pretty messy, so squint your eyes.
They're systematically placed, so we can regex it out when jshint's
new version finally arrives.

Using async/await instead of callbacks due to callback hell, and it also
helps minimising the diff)
