Add core.fmt.json — a complete RFC 8259 JSON library with recursive-descent
parser, serializer, builders, dot/bracket path accessors, and full cleanup.
Supports all 6 JSON value types plus JSON_ERROR for parse error reporting.
Numbers stored as Double via x87 FPU. Unicode \uXXXX escapes handled
(ASCII range emitted, non-ASCII replaced with '?').
Supporting changes:
- core.strings: add int64ToString, doubleToStr (scientific notation for
very large/small values, fixed-point for normal range, trailing zero
trimming), plus unit tests for both
- asuro.pas: wire core.fmt.json.UnitTest into the boot test suite
- mkdocs.yml: add JSON nav entry under Formats
- doc/src/core/fmt/core.fmt.json.md: full API documentation
- doc/src/core/core.strings.md: document int64ToString and doubleToStr
- doc/planning/json.md: implementation plan and design spec
- doc/planning/webgpu.md: WebGPU-over-WASM design plan (software
rasterizer backend for WASM apps importing webgpu.h)
The Drone runner environment does not have `pip` or `mkdocs` on PATH
even when installed via the Docker image. Use `pip3` explicitly and
invoke mkdocs as `python3 -m mkdocs` to ensure reliable execution.
Also add --break-system-packages to the fallback install.
Generate comprehensive documentation for all 173 source units and
integrate mkdocs-material into the build toolchain. Documentation
covers kernel core, x86 architecture, drivers, applications, and
all subsystems with a tabbed navigation structure.
- Add mkdocs.yml with material theme, mermaid support, and tabbed nav
- Add doc/index.md landing page
- Generate doc/src/ markdown for every Pascal unit in src/
- Reorganize planning docs into doc/planning/
- Add compat, lvglh, and toolchain doc sections
- Update Dockerfile to install python3 and mkdocs-material (pinned <2)
- Replace pasdoc-based compile_docs.sh with mkdocs build --strict
- Add compile_docs.sh to the main build pipeline in compile.sh
- Add deploy-docs step in .drone.yml with host volume mount to nginx
- Add site/.gitkeep for build output directory
- 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
Introduce core.panic, a new architecture-agnostic kernel panic engine
with a pre-allocated LVGL BSOD screen. The screen and all widgets are
created at init time so that zero LVGL allocation occurs at panic time.
Layout features:
- Top banner with decoded teapot TGA image (128x128) and title/subtitle
- Two-column content area with dark semi-transparent cards:
- Left: Fault Details, CPU Registers, Process Info, System Info
- Right: Call Stack (full height)
- Pastel red background (#7A2828), monospace text for data sections
Key changes:
- Add core.panic.pas with pre-built BSOD screen, register/trace/system
info formatting, hex conversion helpers, and syslog fallback
- Add arch.x86.panic.pas as the x86 bridge: packs interrupt registers
into a TRegisterSnapshot and calls core.panic.panic()
- Simplify all 19 x86 fault handlers to one-liner panic calls
- Remove legacy BSOD code from arch.x86.util.pas
- Add teapot.tga (256x256) embedded via splash_tga.asm
- Add LVGL bindings: lv_refr_now, lv_image_create, lv_image_set_src,
lv_image_set_scale, lv_image_set_inner_align, and style helpers
- Wire up panic init and test command in asuro.pas
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
- ramdrive: rewrite from registerDrive callbacks to TFilesystem/TStorage_Volume
hooks (rd_Read, rd_ReadDir, rd_ReadOffset, rd_Identify) and mount via
vfs.mountVolume('/disk/ram', ...). Remove open-slot tracking; VFS now
manages file handles through the FD table.
- vfs: fix PathValid for otDRIVE nodes — split relative path into parent
directory + leaf name, list the parent via readDirCallback, and check
each entry's type so individual files are correctly identified as pvFile
instead of always returning pvDirectory or pvInvalid.
- desktop: replace static array[0..MAX_PROGRAMS-1] program registry with
a dynamic PLinkedListBase. Lazy-init on first registerProgram call.
Remove prog_count := 0 from init so programs registered before
desktop.init (e.g. notepad, diskutil) are no longer wiped.
- filedispatch, wasmrunner: add storagetypes to uses, remove stale Lock
parameter from vfs.OpenFile calls.
- progmanager: clean up duplicate uses clauses and remove invalid
kernel.bsod registration.
- compile_wasuro.sh was copying files to the /code directory which
is not where drone builds from, fixed to use $(pwd) and relative
directories based on the root.
- Add compile_wasuro.sh to sparse-clone Wasuro src/wasm from gitea
(develop branch) with caching to skip redundant pulls
- Update compile.sh to include wasuro build step in pipeline
- Update compile_sources.sh to dynamically discover -Fu paths via
find across src/ and wasuro/ directories
- Extend system.pas with FPC 3.2.2 compilerprocs required by Wasuro:
- 64-bit signed/unsigned div and mod (fpc_div_int64, fpc_mod_int64,
fpc_div_qword, fpc_mod_qword) with correct i386 parameter mapping
- 64-bit multiply (fpc_mul_int64) via three 32-bit MUL instructions
- Float-to-integer intrinsics (Trunc, Round) using x87 FPU
- Memory allocation compilerprocs (fpc_getmem, fpc_freemem)
delegating to kernel kalloc/kfree
- Exception handling stubs (reraise, raiseexception, catches, doneexception)
- setjmp/longjmp for exception address stack
- Fix sInt64 type alias (was longint/32-bit, now int64/64-bit)
- Add serial debug helpers (COM1 $3F8) for bare-metal tracing
- Wire up Wasuro in kernel.pas: init WASM VM, set I/O callback to
syslog, and run all 1103 Wasuro tests (0 failures)
- Update .gitignore to exclude wasuro/ cache directory
- Remove diskcmd, diskutil, notepad, partcmd, volcmd init calls and
uses from kernel.pas — these are programs, not kernel subsystems.
- Move their initialization into progmanager.init() alongside the
other baked-in programs (md5sum, base64_prog, dhclient, etc.).
- Remove diskcmd, diskutil, notepad from kernel's uses clause.
- Add a splash.update() call for the auto-mount volumes step.
- Suppress FPC warnings in compile_sources.sh (-v0e instead of -v0ew).
- New splash unit (src/prog/splash.pas) displays a centered logo,
progress bar and status label during kernel boot. Manually drives
LVGL rendering + video.Flush since gfxd isn't running yet.
- Embed img/asuro.tga into the kernel via NASM incbin stub
(src/stub/splash_tga.asm), assembled in compile_stub.sh.
- Build an lv_image_dsc_t at runtime from the decoded TGA pixel data
and display it at 50% scale using lv_image_set_scale(128).
- Move LVGL init earlier in kernel.pas (right after video enable) so
the splash screen is available before VFS/drivers/network init.
- Sprinkle splash.update() calls throughout kmain to show boot
progress (VFS → drivers → buses → network → tests → desktop).
- Fix targa.pas parser: rename Magic→IDLength, remove erroneous Data
pointer field, compute pixel offset correctly (buffer+18+IDLength),
advance source pointer per pixel, handle bottom-to-top origin flip.
- Unit tests moved before desktop.init; splash.teardown called at 100%
just before handing off to the desktop environment.
- desktop: Resolution/Graphics fields now read from video frontbuffer
and gpu.activeDriverName instead of static multiboot/hardcoded values
- gpu: markAvailable sets ActiveName when no driver is active yet, so
the initial VBE boot driver is reported before any setMode call
- kernel: whitespace cleanup
- 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
