Size of the files is in order of megabytes at max. Storing offset lookup table
to read from file on demand is less efficient than reading from memory for such
size.
Read and store offsets first. Sort them to read values sequentially. Memoize
last offset and value to avoid reading the same value twice. Use seek only when
current possition does not match offset. Optimize seek for short distance by
calling read instead.
to avoid copy pasting code, readerutils gives functions that take visitors as params to decide how a record must be handled
Check encoder exists, and get value of stateless encoder.
fixes code formatting conventions
Fixed output of record with RefId
also fixed readTypedRecord and readRecord to have the proper return types
Check if the type has a sRecordId
Use LRU cache for ESMReaders. When cache capacity is reached close least
recently used ESMReader. Remember the file name if a reader was open. Once the
reader requested again open the file if there is stored name for it. Put
released ESMReader to the back of the free items list. Close ESMReader's from
the front of the free items list.
Cached item can be used only by one client at the same time. If the same item is
requested twice exception is thrown. This should never happen in practice. If
this happens need to fix the client logic.
It's allowed to go over the capacity limit when requesting different readers.
Ideally this should never happen but there will be system error anyway
signalizing about too many open files. Need to fix client logic in this case.
All places that were using a vector of ESMReaders now using the cache. Cache is
local for each use case and there is no need for a thread safety.
This PR fixes an assertion introduced by #3211. For some reason my build originally did not contain assertions despite passing `DEBUG` into cmake, but after deleting `CMakeCache.txt` I have now hit the assertion @glassmancody reported as well.
This PR aims to start addressing `ESM` design issues that have silenced errors we incorporated into groundcover `ESM` loading approaches.
- We move the resolution of `parentFileIndices` from `ESMStore` to `ESMReader` as suggested in a `TODO` comment.
- We improve a highly misleading comment which downplayed the significance of `parentFileIndices`.
- We document important preconditions.
- We move a user facing error message to the highest level and improve its context.
- We remove an inappropriate `setGlobalReaderList` method. We now pass this reader list into the method that requires it.
- We remove a thoroughly pointless optimisation of `Store<ESM::LandTexture>`'s construction that has unnecessarily depended on `getGlobalReaderList`.
There should be no functional changes for `master`, but this PR should remove an issue blocking PR #3208.
Merged master/plugin switches into content in openmw
and mwiniimporter.
Extension in content files is now required.
