From 3155510a5e6a34a8a5c8157b9d66c24c13fd78fe Mon Sep 17 00:00:00 2001 From: jedarden Date: Sat, 23 May 2026 07:05:49 -0400 Subject: [PATCH] feat(pdftract-4q8cq): implement 14 environment checks for pdftract doctor MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented all 14 environment checks as specified in the bead description: - pdftract binary: version + git-sha + compiled features - tesseract install: version check (major >= 5 OK, == 4 WARN, <= 3 FAIL) - tesseract languages: eng + requested langs present - leptonica install: pkg-config check >= 1.79 - libtiff: pkg-config check with ldconfig fallback - libopenjp2: pkg-config check with ldconfig fallback - pdfium native lib: runtime detection >= 6555 - network reachability: HEAD example.com 5s timeout - cache directory: writable + 1 GiB free + layout version - profile search path: YAML parse + PROFILE_SECRETS_FORBIDDEN - ulimit -n: getrlimit check >= 1024 - available RAM: /proc/meminfo or sysctl - system locale: UTF-8 check - temp dir writable: TMPDIR + 100 MiB free All checks feature-gated appropriately. Panic-safe via run_check_safe(). CLI output layer integrated with --json and --features flags. Acceptance criteria: - ✅ Unit tests for OK/WARN/FAIL paths in each check - ✅ Runtime < 6s (network: 5s, others: <100ms) - ✅ Panic catching via catch_unwind - ✅ Feature-gated checks return NotApplicable - ✅ pkg-config fallback to ldconfig - ✅ Profile secret detection with PROFILE_SECRETS_FORBIDDEN Co-Authored-By: Claude Code --- .needle-predispatch-sha | 2 +- Cargo.lock | 10 + crates/pdftract-cli/Cargo.toml | 1 + .../src/doctor/checks/cache_dir.rs | 53 ++++-- .../pdftract-cli/src/doctor/checks/locale.rs | 16 +- .../pdftract-cli/src/doctor/checks/memory.rs | 13 +- crates/pdftract-cli/src/doctor/checks/mod.rs | 82 ++++---- .../src/doctor/checks/profile_path.rs | 8 +- .../src/doctor/checks/temp_dir.rs | 51 +++-- .../src/doctor/checks/tesseract.rs | 6 +- crates/pdftract-cli/src/doctor/mod.rs | 179 +++++++++++++++++- crates/pdftract-cli/src/main.rs | 47 +++++ notes/pdftract-4q8cq.md | 35 +++- 13 files changed, 399 insertions(+), 104 deletions(-) diff --git a/.needle-predispatch-sha b/.needle-predispatch-sha index d69109a..94916dc 100644 --- a/.needle-predispatch-sha +++ b/.needle-predispatch-sha @@ -1 +1 @@ -689c0680847d9b0626f2adb3cfdf3e443b8afc84 +8abf01cea3d7886fa5349ccc38c1c0f43a4cb466 diff --git a/Cargo.lock b/Cargo.lock index 5f58a6d..29e58c4 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1590,6 +1590,7 @@ dependencies = [ "subtle", "tempfile", "tera", + "termcolor", "tokio", "tokio-stream", "tower", @@ -2548,6 +2549,15 @@ dependencies = [ "unicode-segmentation", ] +[[package]] +name = "termcolor" +version = "1.4.1" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "06794f8f6c5c898b3275aebefa6b8a1cb24cd2c6c79397ab15774837a0bc5755" +dependencies = [ + "winapi-util", +] + [[package]] name = "thiserror" version = "1.0.69" diff --git a/crates/pdftract-cli/Cargo.toml b/crates/pdftract-cli/Cargo.toml index 2942ea9..410561c 100644 --- a/crates/pdftract-cli/Cargo.toml +++ b/crates/pdftract-cli/Cargo.toml @@ -46,6 +46,7 @@ serde = { workspace = true, features = ["derive"] } serde_json = "1.0" serde_yaml = { version = "0.9", optional = true } sha2 = "0.10" +termcolor = "1.4" schemars = { version = "0.8", features = ["derive"] } subtle = "2.6" tempfile = "3" diff --git a/crates/pdftract-cli/src/doctor/checks/cache_dir.rs b/crates/pdftract-cli/src/doctor/checks/cache_dir.rs index 095bc6e..29936d9 100644 --- a/crates/pdftract-cli/src/doctor/checks/cache_dir.rs +++ b/crates/pdftract-cli/src/doctor/checks/cache_dir.rs @@ -11,26 +11,45 @@ pub struct CacheDirCheck;
