* Rename SceKernelIovec to OrbisKernelIovec
Fixes the naming scheme to match the rest of the project.
* Type fixups
Noticed this while working on the actual thing this PR is about.
* More type fixups
* Update file_system.cpp
* Abstract directory handling
* Clang
* Directory fstat
* Fix dirent loading logic
* PfsDirectory size
Seemed to be hardcoded when I ran tests, so I've hardcoded it here.
Also fixed up the reclen-aligning logic based on hardware observations.
* GetDents cleanup
Bring back the bytes < 512 error return from before, as that's still something that can be checked for out here.
I've also swapped the file type stuff to run from a switch case, so that the check for invalid file type can be used as the default case
* Support reading directories
* getdents
For PfsDirectory, getdents behaves like read does on normal directories. Since dirents are stored internally with a different struct, this means getdents has to convert the dirents before returning data.
For NormalDirectory, getdents is identical to read, so it can just call read and set the basep output.
* Directory readv
* Directory preadv
Since the file mutex is locked before these calls, messing with dirents_index like this shouldn't cause any weird side effects.
* return ORBIS_OK instead of 0
to better align with our coding standards.
* Directory lseek
* Un-modify CMakePresets.json
I keep this modified locally for Linux, but accidentally pushed it.
* Clang
* Fix mac compile
* Potential windows compile fix?
* Filename fix
* Fix normal directory d_reclen
* Comment cleanup
* Remove unnecessary dirent conversion logic
On real hardware, the records are still returned with the same reclen, despite the change in structure.
* PfsDirectory dirents_index fixes
Some weird stuff happens once you reach eof on directories.
Thankfully, PfsDirectories are rather tame in this regard.
* Change comment
* Rewrite normal directory reads
The logic for these seems to behave like a normal file, so instead of tracking a dirents_index, keep an internal buffer representing the file contents, and copy that to output buffers as needed.
* Update pfs_directory.cpp
* Clang
* Fix normal dirents
When rewriting the code, I forgot to account for the increased reclen value for the last dirent in the buffer.
* PfsDirectory::lseek fixes
Based on some additional tests, it seems like lseek unconditionally returns dirents_index, not the actual file position.
Also fixed some bugs with the logic for calculating the proper offset when games do wonky things, and fixed a potential area where games could crash.
* Downgrade stat and fstat log to debug
These functions can get pretty spammy.
* PfsDirectory: Properly track if end of file is reached
Using the metric `dirents_index < directory_content_size` fails when `directory_content_size` is larger than the actual directory size we report.
Since, from what I can tell, PfsDirectories shouldn't ever report more than 0x10000 bytes for size, this change is necessary.
* Revert "PfsDirectory: Properly track if end of file is reached"
I need to do some hardware tests to see if all this excess logic is actually necessary.
* Fix PfsDirectory directory_size
Turns out, if your game has over 1000 files in a folder, it will actually cause the size to increase.
* Update copyright date
* Move devices and directories into file_sys
I've also updated the copyright dates on all these files.
* C++ style type casts
* Remove unnecessary memset
* Use a vector for the data buffer
Simplifies logic for freeing the buffer, based on review suggestions.
* Fix potential oob array access
* Change type casts in Create function
* Clang
* std::memcpy instead of memcpy
* NormalDirectory::lseek cleanup
* Create constants for directory alignment values.
* Use const wherever possible
* Includes cleanup
* sceKernelOpen: Clean up flag handling
* sceKernelOpen: fix params
Based on decompilation, the second parameter of _open should be flags.
Additionally swaps the return and parameter types to align with our current standards.
* sceKernelOpen: Fix errors
Based on POSIX spec, if part of the path is missing, ENOENT is the correct return.
Additionally, decompilation suggests that open sets errno too.
* Fix exports
Fixes function exports to align with what they should be, based on what I've seen from decompilation and our module generator.
* Proper errno behavior on open
Since sceKernelOpen calls posix_open, errno should be set during this process.
Simplest way to handle that is to move the actual open code to posix_open and adjust error cases accordingly.
* Reorganize open calls, add error log
* Improve close
Removes the EPERM return, as it makes no sense, and swaps sceKernelClose with posix_close to properly emulate errno behavior.
* Fix log on close
* posix_open fixups
* Readd hack in posix_close
It's either this, or removing LLE DiscMap.
Or shadow implements posix sockets.
* Missing exports
Commented out while I gradually work through them all
* Remaining placeholder exports
* Swap some stuff around
I see nothing that suggests "open" only takes two parameters, so this should be completely safe.
It's also more accurate to how these are handled in libkernel, and means I won't need to reorganize anything for readv and writev.
* Update file_system.cpp
* Implement write and posix_write
* Oops
* Implement posix_readv and sceKernelReadv
Also fixes error behavior on readv, as that function shouldn't be returning any kernel error codes.
* Move sceKernelUnlink
Will deal with this one later, was just annoyed by how it's location doesn't align with the export order.
* Cleanup readv
* Implement posix_writev and sceKernelWritev
Also fixes error behavior on writev, since it shouldn't ever return kernel errors (since our device files return those)
* More cleanup on older functions
* Swap around sceKernelLseek and posix_lseek
This ensures that these have the correct error behavior, and makes their behavior align with the updated implementations for earlier functions.
* Update file_system.cpp
* Implement read
Also fixes error behavior
* Swap sceKernelMkdir and posix_mkdir
Fixes errno behavior on kernel calls, also fixed some incorrect error returns.
* Fix errno behavior on sceKernelRmdir
Also reduces function logging to bring it closer to the level of logging seen in other filesystem functions.
* Slight clean up of sceKernelStat
Fixes error behavior and changes some of the old data types.
* Refactor fstat
Fixes errno behavior, implements fstat, and shifts exports around based on file position.
Might reorganize function locations later though.
* Implement posix_ftruncate
Implements posix_ftruncate and fixes errno behavior for sceKernelFtruncate
* Add missing error conversions for more device functions
* Implement posix_rename, fix sceKernelRename errno behavior
* Add posix_preadv and posix_pread
Also fixes some incorrect error returns, fixes errno behavior, and removes an unnecessary hack.
* Fix compile
* Implement posix_getdents, getdirentries, and posix_getdirentries
Also fixes errno behavior for the kernel variants of these functions.
* Fix errno behavior of sceKernelFsync
* Implement posix_pwrite and posix_unlink
Also fixes errno behavior in related functions.
* Update file_system.cpp
* Remove SetPosixErrno
Ideally, we've handled all possible error conditions before calling these functions, so treat errors in platform-specific code as IO errors and return POSIX_EIO instead.
* Update header exports
Not sure where these get used, but might as well keep them consistent with the rest of this.
* Check if file exists before calling platform-specific code
Bloodborne checks if a file doesn't exist using open, checking if it specifically failed with error code ENOENT. To avoid working with platform-specific errnos, add a proper error return for if the file doesn't exist.
Fixes a regression in Bloodborne.
* Clang
Out of all the changes, this is apparently the only thing Clang-Format doesn't like.
I'm honestly surprised.
* Improve error checks on posix_unlink
Just because a file isn't opened doesn't mean the file doesn't exist.
Fixes the error returned if host_path.empty(), and removes the error return for when GetFile fails.
* Fix the Bloodborne fix
* Limit exports to tested functions
* More confirmed working exports
* Remaining stuff my games can test
* FS exports from firmware tests
* Bring back missing exports from main
I don't have any bootable things that call these, but since they were working well enough on main, they should be fine to readd.
* Add export for posix_pread
Spotted in Dreams a while back, might as well add it.
* Revert "Remove SetPosixErrno"
This reverts commit bdfc0c246c.
* Revert SetPosixErrno changes
shadow's using it for posix sockets, so significant modifications would introduce unnecessary merge conflicts.
* Update comment
* Add EACCES errno to SetPosixErrno
Seen in Gravity Rush.
Also reorganizes the switch case based on the posix errno value, since ordering by errno makes no sense on some OSes.
* More export fixups
Missed these during my initial pass through FS stuff because they were in kernel.cpp for some reason.
* Symbols from FS tests
Tested by messing around with firmware elfs, these atleast don't cause any crashes.
* Remove inaccurate error behavior
Seek can have offsets past the end of a file.
Also add logging for two valid whence values that are unsupported on Windows.
I'll need to verify that SEEK_HOLE and SEEK_DATA correspond to 3 and 4 respectively, I've yet to check source to verify.
* Fix error log
Oops
* Clang
Clang
* Remove close hack
Since LLE libSceDiscMap is no longer a concern, this hack shouldn't be needed.
Since sockets are still stubbed, and close can be used on sockets, I've added a warning log just in case this still occurs in some titles.
* Change SetPosixErrno unreachable to warning
I changed it to an unreachable in an earlier commit to make testing easier.
At this point, having an unreachable for this seems unnecessary, so change it to a warning instead.
* Remove Bloodborne hack
Games should be able to unlink files that aren't opened file descriptors. As far as I've tested, this doesn't break Bloodborne.
