JosJuice ca36c977d9 DiscIO: Remove m_partition and m_volume from FileSystem
The last commit made m_partition unnecessary, and m_volume
has been unnecessary ever since the PR that added DiscExtractor.

JosJuice 5e3c98af1d DiscIO: Add a Volume::ReadSwappedAndShifted function
This is a fairly common operation, so let's make a utility
function for it to cut down on code duplication.

JosJuice f7032f8deb FileSystemGCWii: Don't add 0-size files to m_offset_file_info_cache
This is done in order to reduce the risk of files not being added
due to them having the same end offset as another file.

JosJuice 93e9740683 Drop unnecessary check from FileSystemGCWii::FindFileInfo
If the current file_info is a file, the ranged for loop will
run 0 times, and we'll reach the last line of the function.

JosJuice b440dbd998 FileSystemGCWii: Use case insensitive comparison in FindFileInfo
This was a regression in f49b64c. Some games seem to name the

JosJuice e3a2cd827a Filesystem: Do more validity checking in the constructor
This makes it possible to catch errors earlier so that file systems
simply fail to load instead of behaving oddly. It also makes it possible
to check for errors that weren't checkable before, like the end of a
directory being after the end of the parent directory.

JosJuice ee27be06d7 Filesystem: Add a cache for finding file info by disc offset
FileMonitor calls this every time a read happens, and there's no code that
only calls this a small number of times, so having a cache is worthwhile.

JosJuice 87916fe099 Filesystem: Replace GetFileList()
Instead of expecting callers to know how the size of directory file infos
relates to which files are in which directories, filesystems now offer a
GetRoot() method, and file infos offer a way to get their children. As
a bonus, m_FileInfoVector no longer has to be created and kept around
in RAM. Only the file info objects that actually are used are created.

JosJuice afe2bc60f6 Filesystem: Initialize everything in constructor
Not initializing until the filesystem is used is good when
a filesystem is constructed and then never used, but nobody does that.
This simplifies the code a little and lets all methods be const.

JosJuice d6ee7ec32c Filesystem: Read the entire FST in one go
Instead of using lots of small scattered reads to read the FST,
only one big read is used, which is more efficient.

This also means that the FST only allocates memory once and stores all
strings close to each other - good for the CPU cache. The file info
objects use pointers to this FST memory of containing data themselves.
Keeping around the big m_FileInfoVector containing objects with only
pointers is a bit unnecessary, but that will be fixed soon.

JosJuice f49b64caff Filesystem: Rewrite finding file info by path for performance
Instead of calling GetPathFromFSTOffset for every file info, FindFileInfo
now only looks at names in directories that are included in the path.
For the common case of searching for "opening.bnr", this means that
only root-level files and directories have to be searched through.
2017-06-13 22:41:02 +02:00
JosJuice 7c45afecb2 Filesystem: Use file info in arguments instead of path
Some callers already have the file info, making the relatively slow
FindFileInfo calls unnecessary. Callers that didn't have the file info
will now need to call FindFileInfo on their own.

JosJuice 07d3a39aeb Filesystem: Replace file info's full path with name
Some callers (i.e. ISOProperties) don't want the full path, so giving them
it is unnecessary. Those that do want it can use GetPathFromFSTOffset.
Not storing full paths everywhere also saves a small bit of RAM and is
necessary for a later commit. The code isn't especially pretty right now
(callers need to use FST offsets...) but it'll become better later.

JosJuice 5021b4a567 Filesystem: Replace FileInfo struct with interface
GC/Wii filesystem internals shouldn't be exposed to other classes.
This change isn't especially useful by itself, but it opens up the
way for some neat stuff in the following commits.

I replaced m_OffsetShift with m_Wii in bb93336 to support

JosJuice 19b8f1c10a VolumeWiiCrypted: Replace ChangePartition with a partition parameter
By removing mutable state in VolumeWiiCrypted, this change makes
partition-related code simpler. It also gets rid of other ugly things,
like ISOProperties's "over 9000" loop that creates a list of
partitions by trying possible combinations, and DiscScrubber's
volume swapping that recreates the entire volume when it needs to
change partition.

JosJuice c7e747d775 DiscIO: Improve IVolume::Read32 error handling
Callers can now check whether reads fail, either by checking the return
value or by setting the buffer to a known bad value and seeing if it stays
untouched. I've added error checks to FileSystemGCWii and Boot_BS2Emu,
but not to Boot since it doesn't check any of its other reads either.

JosJuice 6c25c63301 Limit size of loaded file systems
If a disc image is malformed in a specific way, Dolphin
will try to allocate a lot of memory, making it crash.
To avoid that, this change adds an artificial limit for
the size of file systems that Dolphin will try to load.

JosJuice 618ccf6109 Remove DiscScrubber::GetDOLSize in favor of IFileSystem::GetBootDOLSize
IFileSystem::GetBootDOLSize acts the same. The only difference is that it
reads the DOL offset on its own, but this change makes that optional.
