- Remove FAT_WRITE_PREALLOC_BYTES (redundant at typical cluster sizes)
- Simplify fatPreallocClusterCount to always return MAX_CLUSTERS
- FAT32CloseFile: truncate pre-allocated tail clusters back to ByteSize
on close, freeing FAT chain entries beyond the file's real size
- Add TFATWriteRef + WriteRefs[32] in TFATVolumeCtx and Registered flag
on TFATOpenFile to track concurrent write handles per dir entry
- fatRegisterWriteHandle / fatUnregisterWriteHandle: CLI-guarded slot scan
keyed by (DirLoc.SectorLBA, DirLoc.EntryIdx)
- Register on first FAT chain extension in FAT32EnsureCapacityForWrite
- Truncation in FAT32CloseFile skipped unless this is the last writer
(prevents RunMap corruption in concurrent-open scenarios)
- Add forward decl for fatFreeClusterChain to fix ordering issue
- app.iotest: update default path to /disk/vol2/IOTEST.BIN
- Add TStorageLifecycleWatch with watch_lifecycle/unwatch_lifecycle API (up to 32 watchers)
- Add notify_lifecycle to broadcast mount/unmount/format events to registered callbacks
- Replace raw puint32 config in format_volume with typed PFSFormatParams
- Add volume_is_busy, volume_is_formatting, volume_set_mounted helpers
- Add lifecycleFlags field to TStorage_Volume for tracking busy/formatting state
- Expand app.diskutil with improved commands and volume state reporting
- Minor improvements to core.util, arch.x86.util, proc.mgr, VFS, and flatfs
- Remove obsolete driver.storage.fs.fat32.old.pas
- Add SYM_TRASH toolbar button wired to fb_delete_cb (was missing entirely)
- Filter '.' and '..' entries in fb_collect_cb so they never appear
- Rewrite deleteFile/deleteDir/renameFile to use raw sector scanning
instead of getDirEntries linked-list indices (fixes gap mismatch)
- Handle root directory correctly (use bootRecord^.rootCluster instead
of assuming entry 0 is '.')
Removed driver.hid.mouse dependency that caused page fault on close.
Context menu now triggers via LV_EVENT_LONG_PRESSED on content rows.
Cleaned up onClose teardown ordering and removed debug syslog markers.
- Add extension-based dispatch to driver.storage.filedispatch with typed
union (variant record THandlerKind = hkMagic/hkExtension)
- Extract file-type icon constants and mapping to core.gfx.fileicons
- Add core.search utility (getFileExtension, fmtFileSize, sortStringArray)
- Generate PUA bitmap icon fonts (32/64/128px) from Font Awesome via
gen_file_icons.py + compile_icons.sh toolchain
- Integrate file dispatch into file browser (double-click triggers dispatch)
- Register notepad as handler for text file extensions
- Fix init order in app.mgr (filedispatch.init before app inits)
- Refactor notepad from singleton to multi-instance (up to 8 windows)
using instance array, findStateByWid, and LVGL user_data on msgboxes
- File picker (app.filepicker.pas): add otSYMLINK to directory case in
fp_collect_cb so symlinks like /sys appear as navigable directories
- VFS: add RemoveVirtualTree() to recursively free vdir/symlink trees
- VFS UnitTest: clean up /utest_vfs tree after all tests
- STORTEST: clean up /st_test tree after tests, fix listing leak in
cmd_stortest (GetDirectoryListingFrom result was never freed)
- Boot mount: auto-mount boot drive at /boot via mountVolume() instead
of symlink; remove /boot and /cfg from init() vdirs
- mount.asr: remove boot line (now only 'mnt {device}/sys /sys')
- Add mount.asr parser in auto_mount_volumes: reads MOUNT.ASR from boot
volume root, parses 'mnt {device}<src> <target>' lines, expands {device}
to the boot volume's /disk/volN path, creates symlinks for each entry
- Remove old asr.mnt persistent mount logic from auto_mount_volumes
- Remove persistent mount write ([p] flag) from MOUNT shell command
- Remove hardcoded /boot mount for boot volumes (now driven by mount.asr)
- Add iso/mount.asr with default /boot and /sys symlinks
- Update doc/vfs.md with mount.asr documentation
- 5-phase VFS architecture overhaul (path resolution, dir cache, watch/notify,
symlinks, async API)
- Add character/block device node layer with /dev/null and /dev/zero built-ins
- RegisterDevice() API for custom device nodes with read/write/size callbacks
- Merge TOpenMode + TWriteMode into single TOpenMode enum
(omRead, omWrite, omCreate, omReadWrite, omStream)
- Add stream write support: WriteFile/WriteFileAsync now accept omStream handles
with auto-advancing offset for both device and volume FDs
- Add PPWriteOffsetHook type and writeOffsetCallback field to TFilesystem
- Add PPReadOffsetHook-based streaming reads for FAT32 and ISO9660
- Update all callers (notepad, edit, inio, wasm runner, filepicker, filedispatch,
vterminal, stdio) to new 2-param OpenFile API
- 77 unit tests (0 failures) covering path ops, dir cache, symlinks, watch,
device nodes, and stream read/write
- Add doc/vfs.md — comprehensive public VFS API documentation
Removes per-lookup heap allocation (MD5Buffer/kfree) in favour of a
single zero-allocation FNV-1a32 pass. Drops core.enc.md5 dependency
from core.ds.hashmap.
- core.enc.fnv1a: FNV-1a 32/64-bit non-cryptographic hash with UnitTest
- core.enc.djb2: DJB2 XOR/Add 32/64-bit hash variants with UnitTest
- core.ds.bloom: probabilistic bloom filter (Bloom_New/Add/Test/Clear/Free)
using double hashing (FNV-1a32 + DJB2_32) with UnitTest
- core.ds.types: add TBloomFilter / PBloomFilter record
- asuro.pas: wire all three UnitTests into boot test suite
- diskutil: add proc_pid global, diskutil_entry idle proc, create process
on launch with setWindowOwner, kill on close, zero proc_pid in init
- notepad: add pid field to TNotepadState, notepad_entry idle proc, create
process on launch with setWindowOwner, kill pid in doCloseWindow
- both apps now appear in PS and are manageable via KILL/TERMINATE
- Decode multiboot boot_device byte in storagemanager to identify boot device
- Add isBootDevice to TStorage_Device; propagate isBootDrive to volumes
- Create /boot VFS directory at init; mount boot volume there in auto_mount_volumes
- Fix getDirEntries skipping \-marked (deleted) FAT32 entries to prevent
triple fault when navigating into a deleted directory via file picker
