v3.60 Source Recovery — Missing Dependency Fix

Date: February 16, 2026
Status: ✅ Complete
Build: TB11-01x32 (supersedes PB11-00x32)
Source: Recovered from src/x86/v3_60/ legacy source archive

Summary

ConstructiVision v11 (src/PB11-00x32/) shipped with 12 missing AutoLISP modules and their associated DCL dialogs, causing 3 crash paths and 12 silent load failures at startup. All missing source files were recovered from the v3.60 codebase (src/x86/v3_60/) and merged into the new test build src/TB11-01x32/.

This increases the build from 134 files (84 .lsp, 33 .dcl) to 195 files (126 .lsp, 44 .dcl) — a net gain of 61 files, resolving all known missing-dependency issues documented in constructivision-v11-architecture.md §21.

Problem Statement

The v11 architecture audit (see legacy documentation) identified:

  • 12 .lsp modules listed in csvlst (the startup load list) but absent from the PB11-00x32 build

  • 3 critical crash paths where missing modules caused undefined-function errors

  • 9 silent load failures at startup where (load ...) calls failed for modules with no visible UI trigger

User Impact

mp_dlg → Standard Opening toggle

wd_dlg.lsp

wc_dlg.lsp

sdwg_dlg → Wall Line button

wall_dlg.lsp

Silent Failures (Before Fix)

These 9 modules were loaded at startup via csvlst but had no .lsp file on disk:

weld.lsp, weldconn.lsp, wc_edit.lsp, wcenable.lsp, wclist.lsp, wcpage.lsp, wdenable.lsp, wdpage.lsp, warning.lsp

Resolution

Source Recovery from v3.60

The complete v3.60 source archive (src/x86/v3_60/) contains all 12 missing modules plus 30 additional files that were either removed or never carried forward to the v11 build. All files were imported into the new test build src/TB11-01x32/.

Deployment

The TB11-01x32 build is deployed to test VMs via Git sparse checkout with a nightly auto-pull:

  • Repository: git@github.com:ConstructiVision/ConstructiVision.git

  • Sparse path: src/TB11-01x32

  • Local path: C:\Repos\Constructivision\src\TB11-01x32

  • Junction: C:\Program Files\ConstructiVision → sparse checkout path

  • Nightly task: “ConstructiVision Git Pull” at 22:00 on VMs 108, 109, 201, 202

  • Manual pull: git-pull.bat on each VM desktop

See 06-testing-validation.md § Nightly Build Deployment for full details.

Assumptions and Risks

Assumptions

  1. API compatibility — v3.60 modules are compatible with the v11 runtime. Both versions target AutoCAD 2000 AutoLISP/DCL, so function signatures and global variable contracts should be identical.

  2. No breaking refactors — The 12 missing modules were removed from PB11-00x32 intentionally (likely because weld connections and standard openings were incomplete features), not because they were replaced by something else. The csvlst load list was never updated to remove them.

  3. Additional v3.60 modules are safe — The 30 extra .lsp files beyond the 12 missing dependencies are assumed to be either older versions of existing modules or supplementary features. They should not conflict since AutoLISP functions are globally scoped and later definitions override earlier ones.

  4. Stub functions remain stubs — footing.lsp and column.lsp (both 4-line alert stubs) exist in both PB11 and TB11. These features were never implemented in any version.

  5. Compiled functions unchanged — csvreg and csvtech (compiled into CSV.VLX with no source) are assumed identical between PB11 and TB11 since the same VLX binary is used.

Risks

Risk

Likelihood

Mitigation

v3.60 modules reference globals that v11 renamed

Low

Test all 3 formerly-crashing paths on VM 108

Additional v3.60 modules override v11 improvements

Medium

Compare function names across both sets; v11 loads later and wins

Weld connections / standard openings are incomplete even with source restored

Medium

These were disabled in v11 UI for a reason — test thoroughly before enabling

warning.lsp behavior differs from what v11 callers expect

Low

Test overwrite/save scenarios on all VMs

Validation

Test Paths to Verify

The 3 crash paths from the v11 architecture test matrix must be retested:

Test ID

Expected (Before)

Expected (After)

T-A2-1-WD

mp_dlg → Standard Opening → wd_dlg

⚠️ CRASH

Startup Validation

Load the application and confirm no errors in the AutoCAD command line. All 93 modules in csvlst should load without error messages.
