t3hn3rd 1ae867d929 fix: adapt subsystems to new VFS volume API and fix desktop program registry
continuous-integration/drone/pr Build is passing
continuous-integration/drone/push Build is passing
- 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.

t3hn3rd 40a1c05728 Fix: missing imports in wasmio.pas 2026-03-07 21:26:26 +00:00
t3hn3rd 2bfbb44cfb feature: WASM execution pipeline, file dispatch, RAM drive, and VFS handle table
- Add file-type dispatch registry (filedispatch.pas) matching files by
  magic header bytes and routing to registered handlers
- Add WASM integration layer: wasmshim, wasmio, wasmrunner, wasmcleanup
  providing full WASI Preview1 bridging (fd_write/read, proc_exit,
  clock, random, args passthrough, environ stubs)
- Add RAM drive (ramdrive.pas) providing in-memory VFS at /disk/ram
  with a built-in hello world WASM binary
- (Placeholder) Implement VFS handle table for proper
  open/read/write/close/filesize routing through registered drives
  and devices
- Integrate file dispatch into vterminal for unknown commands, supporting
  both foreground and background execution of dispatched files
- Expand progmanager init with PS, KILL, TERMINATE, DEV, DISK, MEMRAW,
  BSOD, IFCONFIG, ARP, and TCP commands; wire up ramdrive, filedispatch,
  and wasmrunner initialization
- Replace serial.sendString with syslog.logln in desktop launcher

t3hn3rd 8ab2d0d04f fix: drone pipeline not working
- 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.

t3hn3rd b51881ced7 feat: integrate Wasuro WASM runtime into Asuro build chain
- 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

t3hn3rd 0d6f1e006c feature: preemptive process management - implementation progress
Implement a preemptive multitasking system for the Asuro kernel.

Context Switching & Scheduling:
- Custom IRQ0 ISR (contextswitcher.pas) with PUSHAD/POPAD ESP-swap
- Round-robin scheduler with priority-based quantum
- Process table using DList of PProcessContext pointers
- Idle process (PID 0) replaces kernel HLT loop

Process Lifecycle:
- create/kill/terminate/sendMessage API (processmanager.pas)
- Process states: Created, Running, Ready, Suspended, Awaiting,
  Finished, Error
- Parent-child tracking (ParentID, smChildExited notification on reap)
- proc_yield, proc_sleep_ms, proc_await, proc_suspend, proc_exit

Resource Binding & Cleanup:
- Per-process resource list
  (bindResource/unbindResource/unbindAllResources)
- TCP sockets auto-bound to owning process (OwnerPID on TTCPSocket)
- socket_cleanup + auto-unbind in DestroySocket

VTerminal Refactor:
- Multi-instance design (heap-allocated TVTermState per terminal)
- Foreground process with incremental stdout/stderr drain via LVGL timer
- Ctrl+C kills foreground process (killForeground)
- Per-terminal CWD, dir stack, FS builtins (CD/LS/PUSHD/POPD)
- Background job support (& suffix, JOBS/FG commands)
- Command history (Up/Down arrow)

Command Consolidation:
- 14 commands extracted from 9 units into centralized progmanager.pas
- Command procedures exported in host unit interfaces
- E1000/TRACER/stdio builtins kept in-place (conditional/circular)

New Units:
- src/include/proctypes.pas — process type definitions
- src/processmanager.pas — core process manager
- src/prog/ping.pas — standalone ICMP ping process
- src/prog/testcmd.pas — test command (proc_sleep_ms demo)
- src/testprocs.pas — process subsystem smoke tests

Misc:
- ICMP callbacks gain userData parameter for concurrency-safe ping
- CLI/STI guards on kalloc/kfree (lmemorymanager.pas)
- LV_KEY_CTRLC constant + Ctrl+C interception in LVGL keyboard hook
- Window owner PID tracking (windows.pas)
- ISR_32 gate override support (isrmanager.pas)
