From 1e31f3a3fc7b5414ae2066da76afbdce8ce5b901 Mon Sep 17 00:00:00 2001 From: Richard Feldman Date: Sat, 29 Nov 2025 17:28:46 -0500 Subject: [PATCH 1/6] Fix string literal pattern matching in match expressions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit String patterns were always falling through to the wildcard case because canonicalization extracted the wrong token content. The code was using e.string_tok (which points to the StringStart delimiter) instead of getting the actual string content from e.expr's string_part tokens. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- docs/BUG_FIX_PLAN.md | 310 ++++++++++++++++++++++++++++++ src/canonicalize/Can.zig | 66 +++++-- src/cli/test/fx_platform_test.zig | 86 +++++++++ 3 files changed, 450 insertions(+), 12 deletions(-) create mode 100644 docs/BUG_FIX_PLAN.md diff --git a/docs/BUG_FIX_PLAN.md b/docs/BUG_FIX_PLAN.md new file mode 100644 index 0000000000..d5f90c1282 --- /dev/null +++ b/docs/BUG_FIX_PLAN.md @@ -0,0 +1,310 @@ +# Bug Fix Plan for Roc Compiler Issues + +This document provides a detailed plan for fixing the remaining bugs found during testing. + +## Status Summary + +| Bug # | Description | Status | Difficulty | +|-------|-------------|--------|------------| +| 1 | Type annotations on helper functions panic | FIXED | - | +| 2 | Tuple pattern matching panic | FIXED | - | +| 3 | Custom type aliases panic | FIXED | - | +| 4 | `?` operator not implemented | **BUG** | Medium | +| 5-8 | Missing builtins (Num.to_str, List.range, etc.) | Feature Request | - | +| 9 | Numeric fold produces garbage values | **BUG** | Hard | +| 10 | For loop on list literals segfault | FIXED | - | +| 11 | List.first error handling crash | FIXED | - | +| 12 | String literal matching in match broken | FIXED | Medium | +| 13-14 | Args and memory leaks | Platform-specific | - | + +## Bugs Requiring Fixes + +--- + +## Bug 4: `?` Operator Not Implemented + +### Reproduction +```roc +main! = || { + first = List.first(["hello"])? + Stdout.line!(first) +} +``` + +**Error:** `NOT IMPLEMENTED: canonicalize suffix_single_question expression` + +### Root Cause Location +- **File:** `/Users/rtfeldman/code/roc5/src/canonicalize/Can.zig` +- **Lines:** 5073-5079 + +```zig +.suffix_single_question => |_| { + const feature = try self.env.insertString("canonicalize suffix_single_question expression"); + const expr_idx = try self.env.pushMalformed(Expr.Idx, Diagnostic{ .not_implemented = .{ + .feature = feature, + .region = Region.zero(), + } }); + return CanonicalizedExpr{ .idx = expr_idx, .free_vars = null }; +}, +``` + +### How Similar Operators Work + +The `!` (bang) operator is handled at lines 5097-5107: +```zig +.OpBang => { + const can_operand = (try self.canonicalizeExpr(unary.expr)) orelse return null; + const expr_idx = try self.env.addExpr(Expr{ + .e_unary_not = Expr.UnaryNot.init(can_operand.idx), + }, region); + return CanonicalizedExpr{ .idx = expr_idx, .free_vars = can_operand.free_vars }; +}, +``` + +### Fix Plan + +1. **Desugar `expr?` to a match expression:** + ```roc + match expr { + Ok(value) => value, + Err(e) => return Err(e), + } + ``` + +2. **Implementation steps:** + - Canonicalize the inner expression + - Create a match expression with two branches: + - `Ok(value)` pattern → extract and return the value + - `Err(e)` pattern → early return with the error + - Handle free variables from the inner expression + - Use existing `e_match` and `e_return` expression types + +3. **Files to modify:** + - `src/canonicalize/Can.zig` (main implementation) + - May need to add helper functions for generating the match pattern + +### Test File +- `/Users/rtfeldman/code/roc5/test/fx/bug_04_question_mark_not_implemented.roc` + +--- + +## Bug 9: Numeric Fold Produces Incorrect Values + +### Reproduction +```roc +main! = || { + sum = [1, 2, 3, 4, 5].fold(0, |acc, n| acc + n) + Stdout.line!("Sum: ${I64.to_str(sum)}") +} +``` + +**Expected:** `Sum: 15` +**Actual:** `Sum: -3446744073709551616` (garbage value) + +### Root Cause Location +- **File:** `/Users/rtfeldman/code/roc5/src/eval/interpreter.zig` +- **Lines:** 10780-10857 (`for_loop_body_done` handler) + +### How fold Works (Builtin Definition) +From `/Users/rtfeldman/code/roc5/src/build/roc/Builtin.roc:97-106`: +```roc +fold : List(item), state, (state, item -> state) -> state +fold = |list, init, step| { + var $state = init + for item in list { + $state = step($state, item) + } + $state +} +``` + +### Root Cause Analysis + +The `for_loop_body_done` continuation handler has a binding cleanup issue: + +1. **Line 10786:** `body_result.decref(&self.runtime_layout_store, roc_ops);` + - Immediately discards the loop body result without preserving mutable variable updates + +2. **Line 10789:** `self.trimBindingList(&self.bindings, fl.loop_bindings_start, roc_ops);` + - Trims bindings back to the loop scope start + - **BUG:** This removes/corrupts the mutable variable binding (`$state`) that tracks the accumulator + +The execution flow: +1.
