minsungandClaude Opus 5 1f80442f6c feat(ui): options panel with an IndexedDB-backed lineweight display scale
Set the default lineweight scale to 11 px/mm: the value the user matched
against AutoCAD on the actual screen. The 20 px/mm derived from their
screenshot was too heavy in practice - the capture and the monitor do
not share a DPI - so the constant is now only a starting point.

Move the lineweight controls off the toolbar into an Options panel:
display toggle, scale slider plus number box, a readout of what the
drawing's own weights come out to, grid toggle, zoom speed, and a reset.
Settings persist in IndexedDB (hmw-viewer/options) rather than
localStorage, so values keep their type and the store has room to grow
per-drawing later; every call degrades quietly if storage is blocked.

Scale changes still apply to the live materials - each fat batch now
remembers its weight in mm - so dragging the slider retunes a 37MB
drawing instantly.

Verified headless: 0.35mm renders 3-4px at scale 11 and 8-9px at 25,
matching the readout, and the value survives a reload via IndexedDB.

minsungandClaude Opus 5 a924b1ec34 feat(viewer2d): make the lineweight display scale adjustable from the toolbar
The px-per-mm mapping was a hard-coded guess twice over, and the right
value depends on the monitor - AutoCAD has the same knob as the Adjust
Display Scale slider. Expose it: a slider plus a number box next to the
lineweight toggle, with a readout of what the drawing's own weights come
out to (0.35mm -> 7px, 0.50mm -> 10px at the 20 px/mm default). The
value persists in localStorage.

Retuning applies to the live materials instead of rebuilding the scene.
The hairline cut-off is a millimetre value, so changing the scale moves
every weight by the same factor without changing which bucket a segment
belongs to - each fat batch now remembers its weight in mm, and only
material.linewidth is rewritten. That keeps a drag on the slider instant
even on the 37 MB road drawing.

Measured headless on its 0.35mm gutter line: 2-3px at scale 8, 7px at
20, 14px at 40 - matching the readout in each case.

minsungandClaude Opus 5 cf1298749b fix(viewer2d): show lineweight at AutoCAD's display scale (20 px/mm)
Hand test against an AutoCAD capture: the 0.50mm road edge is ~10px
there but only ~4px here. Lineweight is zoom-independent screen pixels,
so the two captures compare directly - the 8 px/mm mapping was 2.5x too
small. AutoCAD's default display scale is one pixel per 0.05mm, so use
20 px/mm (0.35mm = 7px, 0.50mm = 10px, 2.11mm = 42px) and raise the
clamp to 48px.

Add setLineweightScale()/getLineweightScale() so a host can retune it -
AutoCAD exposes the same thing as the Adjust Display Scale slider.

Re-measured headless: the 0.35mm road-gutter line now renders ~7px, so
both weight classes land on the same scale.

minsungandClaude Opus 5 ce3859c487 docs: ship the acadrust MPL-2.0 notice, license text and local patch
The deployed site serves a .wasm with acadrust compiled into it, and our
vendored copy carries one modified MPL file
(src/io/dwg/dwg_stream_readers/object_reader/entities.rs, the read_mesh
array-count bounds fix). That is Executable Form distribution of modified
Covered Software, so MPL-2.0 3.2 requires the Source Code Form to be
available and recipients to be told how to get it. Nothing shipped said
so: no license text, no notice, no obtainable source - the upstream
mirror repos are private.

Add THIRD-PARTY-NOTICES.md plus public/licenses/ (MPL-2.0 text, the
read_mesh patch against the pristine 0.4.1 crate, and a served copy of
the notice), and link them from the page so recipients can actually find
them. Original crate download plus the patch reproduces the exact source
compiled into the wasm.

MPL does not require upstreaming, and the lineweight work did not touch
any MPL file - dwg-wasm/src/lib.rs is our MIT wrapper. docs/license-mpl2-
acadrust.md records the analysis and the checklist for future changes.

## acadrust 0.4.1 — Mozilla Public License 2.0 — **MODIFIED**

| Upstream | https://github.com/hakanaktt/acadrust · https://crates.io/crates/acadrust/0.4.1 |
| Upstream commit | `f249c2f816acf36ee51cd5533716bdd443c2517e` (from the crate's `.cargo_vcs_info.json`) |
| Author | Hakan AK |
| Shipped as | compiled into `assets/acadrust_dwg_bg-*.wasm` (Executable Form) |
**This copy is modified.** One file differs from the published crate:
```
src/io/dwg/dwg_stream_readers/object_reader/entities.rs (read_mesh array-count bounds)
```
The modification bounds `read_mesh`'s array counts by the bits remaining in the
object stream instead of the blanket 100 000-item guard, which truncated and
thereby corrupted large SubD meshes.
### How to obtain the Source Code Form (MPL-2.0 §3.2)
1. Get the unmodified crate source — `cargo vendor`, or
`https://crates.io/api/v1/crates/acadrust/0.4.1/download`, or the upstream
commit above.
2. Apply [`public/licenses/acadrust-0.4.1-read_mesh.patch`](./public/licenses/acadrust-0.4.1-read_mesh.patch)
(`/licenses/acadrust-0.4.1-read_mesh.patch` on the deployed site):
```bash
tar xf acadrust-0.4.1.crate && cd acadrust-0.4.1
patch -p1 < acadrust-0.4.1-read_mesh.patch
```
The result is the exact Source Code Form of the acadrust code compiled into the
shipped `.wasm`. Both the original and the modified file remain under MPL-2.0.

Each Contributor hereby grants You a world-wide, royalty-free,
non-exclusive license:
(a) under intellectual property rights (other than patent or trademark)
Licensable by such Contributor to use, reproduce, make available,
modify, display, perform, distribute, and otherwise exploit its
Contributions, either on an unmodified basis, with Modifications, or
as part of a Larger Work; and
(b) under Patent Claims of such Contributor to make, use, sell, offer
for sale, have made, import, and otherwise transfer either its
Contributions or its Contributor Version.
2.2. Effective Date

become effective for each Contribution on the date the Contributor first
distributes such Contribution.
2.3. Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights granted under
this License. No additional rights or licenses will be implied from the
distribution or licensing of Covered Software under this License.
Notwithstanding Section 2.1(b) above, no patent license is granted by a
Contributor:
(a) for any code that a Contributor has removed from Covered Software;
or
(b) for infringements caused by: (i) Your and any other third party's
modifications of Covered Software, or (ii) the combination of its
Contributions with other software (except as part of its Contributor
Version); or
(c) under Patent Claims infringed by Covered Software in the absence of
its Contributions.
This License does not grant any rights in the trademarks, service marks,
or logos of any Contributor (except as may be necessary to comply with
the notice requirements in Section 3.4).
2.4. Subsequent Licenses
No Contributor makes additional grants as a result of Your choice to
distribute the Covered Software under a subsequent version of this
License (see Section 10.2) or under the terms of a Secondary License (if
permitted under the terms of Section 3.3).
2.5. Representation
Each Contributor represents that the Contributor believes its
Contributions are its original creation(s) or it has sufficient rights
to grant the rights to its Contributions conveyed by this License.
2.6. Fair Use
This License is not intended to limit any rights You have under
applicable copyright doctrines of fair use, fair dealing, or other
equivalents.
2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
in Section 2.1.
3. Responsibilities
-------------------
3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
(a) such Covered Software must also be made available in Source Code
Form, as described in Section 3.1, and You must inform recipients of
the Executable Form how they can obtain a copy of such Source Code
Form by reasonable means in a timely manner, at a charge no more
than the cost of distribution to the recipient; and
(b) You may distribute such Executable Form under the terms of this
License, or sublicense it under different terms, provided that the
license for the Executable Form does not attempt to limit or alter
the recipients' rights in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).
3.4. Notices
You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.
4. Inability to Comply Due to Statute or Regulation
---------------------------------------------------
If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description must
be placed in a text file included with all distributions of the Covered
Software under the name "LEGAL", and included in all Covered Software
distributed in Source Code Form. Except to the extent prohibited by
statute or regulation, such description must be sufficiently detailed
for a recipient of ordinary skill to be able to understand it.
5. Termination
--------------
5.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a particular
Contributor are reinstated (a) provisionally, unless and until such
Contributor explicitly and finally terminates Your grants, and (b) on an
ongoing basis, if such Contributor fails to notify You of the
non-compliance by some reasonable means prior to 60 days after You have
come back into compliance. Moreover, Your grants from a particular
Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the
first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after
Your receipt of the notice.
5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.
5.3. In the event of termination under Sections 5.1 or 5.2 above, all
end user license agreements (excluding distributors and resellers) which
have been validly granted by You or Your distributors under this License
prior to termination shall survive termination.
************************************************************************
* *
* 6. Disclaimer of Warranty *
* ------------------------- *
* *
* Covered Software is provided under this License on an "as is" *
* basis, without warranty of any kind, either expressed, implied, or *
* statutory, including, without limitation, warranties that the *
* Covered Software is free of defects, merchantable, fit for a *
* particular purpose or non-infringing. The entire risk as to the *
* quality and performance of the Covered Software is with You. *
* Should any Covered Software prove defective in any respect, You *
* (not any Contributor) assume the cost of any necessary servicing, *
* repair, or correction. This disclaimer of warranty constitutes an *
* essential part of this License. No use of any Covered Software is *
* authorized under this License except under this disclaimer. *
* *
************************************************************************
************************************************************************
* *
* 7. Limitation of Liability *
* -------------------------- *
* *
* Under no circumstances and under no legal theory, whether tort *
* (including negligence), contract, or otherwise, shall any *
* Contributor, or anyone who distributes Covered Software as *
* permitted above, be liable to You for any direct, indirect, *
* special, incidental, or consequential damages of any character *
* including, without limitation, damages for lost profits, loss of *
* goodwill, work stoppage, computer failure or malfunction, or any *
* and all other commercial damages or losses, even if such party *
* shall have been informed of the possibility of such damages. This *
* limitation of liability shall not apply to liability for death or *
* personal injury resulting from such party's negligence to the *
* extent applicable law prohibits such limitation. Some *
* jurisdictions do not allow the exclusion or limitation of *
* incidental or consequential damages, so this exclusion and *
* limitation may not apply to You. *
* *
************************************************************************
8. Litigation
-------------
Any litigation relating to this License may be brought only in the
courts of a jurisdiction where the defendant maintains its principal
place of business and such litigation shall be governed by laws of that
jurisdiction, without reference to its conflict-of-law provisions.
Nothing in this Section shall prevent a party's ability to bring
cross-claims or counter-claims.
9. Miscellaneous
----------------
This License represents the complete agreement concerning the subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent
necessary to make it enforceable. Any law or regulation which provides
that the language of a contract shall be construed against the drafter
shall not be used to construe this License against a Contributor.
10. Versions of the License
---------------------------
10.1. New Versions
Mozilla Foundation is the license steward. Except as provided in Section
10.3, no one other than the license steward has the right to modify or
publish new versions of this License. Each version will be given a
distinguishing version number.
10.2. Effect of New Versions
You may distribute the Covered Software under the terms of the version
of the License under which You originally received the Covered Software,
or under the terms of any subsequent version published by the license
steward.
10.3. Modified Versions
If you create software not governed by this License, and you want to
create a new license for such software, you may create and use a
modified version of this License if you rename the license and remove
any references to the name of the license steward (except to note that
such modified license differs from this License).
10.4. Distributing Source Code Form that is Incompatible With Secondary
Licenses
If You choose to distribute Source Code Form that is Incompatible With
Secondary Licenses under the terms of this version of the License, the
notice described in Exhibit B of this License must be attached.

License, v. 2.0. If a copy of the MPL was not distributed with this
file, You can obtain one at https://mozilla.org/MPL/2.0/.
If it is not possible or desirable to put the notice in a particular
file, then You may include the notice in a location (such as a LICENSE

# acadrust MPL-2.0 — 의무 사항과 조치 내역
| 항목 | 내용 |
|------|------|
| 작성 목적 | 파서(acadrust, MPL-2.0)를 담은 wasm 을 공개 배포하면서 지켜야 할 의무를 확정하고 조치 내역 기록 |
| 대상 배포물 | `https://dwg-dxf-viewer-sample.pages.dev/` (Cloudflare Pages, 공개) |
| 검토일 | 2026-08-04 |
| 상태 | **조치 완료** — 고지 파일·MPL 원문·패치 동봉, 사이트에서 링크 |
---
## 0. 결론 (세 줄)
1. **이번 lineweight 작업은 MPL 파일을 건드리지 않았다.** 수정한 `dwg-wasm/src/lib.rs`
우리 MIT 코드다. → MPL 의무가 *새로* 생기지 않았다.
2. 그러나 **이전부터** acadrust 를 한 파일 패치해서 wasm 에 컴파일해 공개 배포 중이었고,
그 상태가 **MPL-2.0 §3.2 위반**이었다. 라이선스 원문도 고지도 소스 입수 경로도 없었다.
3. **upstream(hakanaktt/acadrust)에 PR 을 올릴 의무는 없다.** MPL 은 기여 강제가 아니다.
**배포물에 고지 + 소스 입수 경로만 넣으면 된다.** ← 이번에 그렇게 조치했다.
---
## 1. 무엇이 MPL 이고 무엇이 우리 것인가
| 코드 | 위치 | 라이선스 | 이번 세션에서 수정? |
|------|------|----------|---------------------|
| **acadrust 0.4.1** (DWG 파서 본체) | `hmwebviewer/rust/acadrust/` | **MPL-2.0** | **아니오** |
| dwg-wasm (wasm-bindgen 래퍼 + JSON 직렬화) | `hmwebviewer/rust/dwg-wasm/src/lib.rs` | MIT (우리 코드) | 예 (lineWeight 필드 추가) |
| Viewer2D 외 프론트엔드 | `src/` | MIT | 예 |
MPL-2.0 은 **파일 단위(file-level) 카피레프트**다. GPL 처럼 프로젝트 전체로 번지지 않는다.
MPL 파일을 고쳤으면 **그 파일만** MPL 로 유지하고 소스를 공개하면 되고,
MPL 파일을 호출·링크하는 우리 코드(§3.3 의 "Larger Work")는 우리가 원하는 라이선스로 배포할 수 있다.
**`lib.rs` 에 필드 세 개 추가한 것은 MPL 전염 사유가 아니다.**
## 2. 그럼에도 의무가 있는 이유 — 이미 한 파일을 고쳤다
vendored acadrust 를 crates.io 원본과 diff 하면 **정확히 한 파일**이 다르다.
```bash
diff -rq ~/.cargo/registry/src/index.crates.io-*/acadrust-0.4.1/src \
hmwebviewer/rust/acadrust/src
# → src/io/dwg/dwg_stream_readers/object_reader/entities.rs 만 differ
```
`read_mesh` 의 배열 길이를 남은 비트 수로 제한하는 패치다(대형 SubD 메쉬 손상 수정,
[`subdmesh-rendering.md`](./subdmesh-rendering.md)). **이 파일은 Modified Covered
Software** 이고, 그 소스는 MPL 하에 제공되어야 한다.
그리고 `.wasm` 은 acadrust 를 컴파일해 담은 **Executable Form** 이다. 공개 사이트에서
브라우저로 내려보내는 순간 MPL 상 "Distribution" 에 해당한다.
### 적용되는 조항
| 조항 | 요구 |
|------|------|
| §3.1 | Source Code Form 을 배포하면 MPL 하에 배포하고 라이선스 사본을 동봉 |
| **§3.2** | **Executable Form 배포 시**: (a) 해당 Covered Software 의 Source Code Form 을 MPL 하에 제공하고, (b) **수령자에게 그 입수 방법을 알릴 것** (배포 비용 이상 청구 금지) |
| §3.3 | Larger Work(우리 앱)는 다른 라이선스로 배포 가능 — 위 (a)(b)를 지키는 한 |
| §3.4 | 라이선스·저작권 고지를 제거하지 말 것 |
**MPL 에는 upstream 기여 의무 조항이 없다.** §3.2 는 "수령자에게 제공"이지
"원저자에게 반영"이 아니다.
## 3. 위반 상태였던 지점 (조치 전)
- 배포 사이트에 MPL-2.0 **원문 없음**
- acadrust 를 쓴다는 **고지 없음** (README 표에만 한 줄, 배포물에는 미포함)
- 패치된 `entities.rs` 소스를 **얻을 방법 없음**
- `hmwebviewer` GitHub 저장소는 비공개(API 404)
- 샘플 저장소는 사내 gitea
- 즉 공개 배포 대상자가 소스에 접근할 경로가 전무
## 4. 조치 사항 (완료)
### 4-1. 배포물에 동봉
| 파일 | 배포 URL | 내용 |
|------|----------|------|
| `public/licenses/acadrust-MPL-2.0.txt` | `/licenses/acadrust-MPL-2.0.txt` | MPL-2.0 원문 (§3.1·§3.4) |
| `public/licenses/acadrust-0.4.1-read_mesh.patch` | `/licenses/acadrust-0.4.1-read_mesh.patch` | 우리 수정분 diff (§3.2(a)) |
| `public/licenses/THIRD-PARTY-NOTICES.md` | `/licenses/THIRD-PARTY-NOTICES.md` | 컴포넌트·버전·업스트림·수정 여부·복원 절차 (§3.2(b)) |
저장소 루트에도 같은 내용의 [`../THIRD-PARTY-NOTICES.md`](../THIRD-PARTY-NOTICES.md) 를 둔다.
### 4-2. 사이트에서 링크
`index.html` 우측 "Module recipe" 패널 하단에 고지 링크 추가.
§3.2(b) 의 "reasonable manner" 요건은 **수령자가 실제로 찾을 수 있는 위치**를 요구한다.
### 4-3. 소스 복원 절차 명시
원본 크레이트 + 패치 조합이면 컴파일된 소스를 바이트 단위로 재현할 수 있다.
```bash
curl -O https://crates.io/api/v1/crates/acadrust/0.4.1/download
tar xf download && cd acadrust-0.4.1
patch -p1 < acadrust-0.4.1-read_mesh.patch
```
업스트림 커밋 `f249c2f816acf36ee51cd5533716bdd443c2517e` 도 고지에 적어 뒀다
(크레이트의 `.cargo_vcs_info.json` 값).
## 5. 질문에 대한 답
> **"해당 레포(upstream)에 올려야 하나, 배포시 문서만 추가하면 되나?"**
**문서(고지) + 소스 입수 경로만 배포물에 넣으면 된다. upstream PR 은 의무가 아니다.**
| 선택지 | MPL 상 필요? | 판단 |
|--------|--------------|------|
| 배포물에 MPL 원문 + 고지 + 패치 동봉 | **필수** | ✅ 이번에 조치 |
| upstream `hakanaktt/acadrust` 에 PR | 아니오 | 선택 — read_mesh 수정은 일반 버그픽스라 올리면 유지보수 부담이 준다 (권장, 의무 아님) |
| `hmwebviewer` 저장소 공개 전환 | 아니오 | 불필요 — 패치 동봉으로 §3.2 충족 |
| 패치된 acadrust 전체 소스를 이 저장소에 vendoring | 아니오 | 더 엄격한 대안. 189 파일이 샘플 저장소에 들어와 무거워짐. 원본+패치 방식은 배포판(distro) 관행과 동일하고 §3.2 를 충족 |

**아니오.** 이번에 고친 `dwg-wasm/src/lib.rs` 는 MIT 인 우리 파일이고, MPL 파일은
건드리지 않았다(위 §2 diff 로 확인). 의무는 **이전 read_mesh 패치 + wasm 공개 배포**에서
이미 발생해 있었고, 이번에 뒤늦게 정리한 것이다.
## 6. 앞으로 지킬 것 (체크리스트)
- [ ] `rust/acadrust/` 아래 파일을 고치면 → 패치 파일을 다시 뽑아 `public/licenses/` 갱신
- [ ] acadrust 버전을 올리면 → 고지의 버전·커밋·패치를 함께 갱신
- [ ] 새 서드파티를 번들하면 → `THIRD-PARTY-NOTICES.md` 에 행 추가
- [ ] MPL 파일에서 라이선스 헤더 주석을 지우지 말 것 (§3.4)
- [ ] 배포 전 `/licenses/` 3개 파일이 실제로 서빙되는지 확인
## 7. 참고

주의: 화면의 **빨간 선이 두 종류**다. 굵은 쪽이 `도로 가장자리`(0.50mm), 도로 한가운데를
지나는 얇은 쪽이 `Station` 중심선(Default → 헤어라인). 정답지에서 굵게 나오는 것은 전자다.
### 5-5. 정답지 대조 (배율 확정 근거)
lineweight 는 줌과 무관한 화면 픽셀이므로, 두 캡처의 **절대 픽셀 두께**를 그대로 비교한다.

| 25 px/mm (참고) | 12.5 px | 89 px |
캡처 이미지에서 역산한 20 은 실제 화면에서 과했다 — 캡처 DPI 와 사용자 모니터가 달라서다.
최종값은 사용자가 뷰어와 AutoCAD 를 나란히 놓고 맞춘 **11**. 이래서 상수로 못 박지 않고

1. **표시 배율 고정**`LW_PX_PER_MM = 8` 이 상수다. AutoCAD 는 "선가중치 설정 → 표시 배율"
슬라이더로 조절 가능하므로, 필요하면 `setLineweightScale()` 로 노출할 것.
1. **배율 기본값은 환경 의존** — 11 은 특정 모니터에서 맞춘 값이다. 다른 화면에서는
옵션 패널로 다시 맞춰야 한다. `devicePixelRatio` 로 자동 보정하는 것은 검토만 하고
넣지 않았다(캡처·원격 데스크톱 등에서 오히려 어긋난다).
2. **ByBlock 근사** — 블록 자식의 `-2` 는 INSERT 굵기를 상속하지만, 중첩 블록에서
중간 INSERT 가 `-2` 인 경우까지는 추적하지 않는다(점선 처리와 동일한 기존 정책).

## acadrust 0.4.1 — Mozilla Public License 2.0 — **MODIFIED**
| | |
|---|---|
| Component | `acadrust` (DWG/DXF parser, Rust) |
| Version | 0.4.1 |
| License | MPL-2.0 — full text: [`public/licenses/acadrust-MPL-2.0.txt`](./public/licenses/acadrust-MPL-2.0.txt) (`/licenses/acadrust-MPL-2.0.txt`) |
| Upstream | https://github.com/hakanaktt/acadrust · https://crates.io/crates/acadrust/0.4.1 |
| Upstream commit | `f249c2f816acf36ee51cd5533716bdd443c2517e` (from the crate's `.cargo_vcs_info.json`) |
| Author | Hakan AK |
| Shipped as | compiled into `assets/acadrust_dwg_bg-*.wasm` (Executable Form) |
**This copy is modified.** One file differs from the published crate:
```
src/io/dwg/dwg_stream_readers/object_reader/entities.rs (read_mesh array-count bounds)
```
The modification bounds `read_mesh`'s array counts by the bits remaining in the
object stream instead of the blanket 100 000-item guard, which truncated and
thereby corrupted large SubD meshes.
### How to obtain the Source Code Form (MPL-2.0 §3.2)
1. Get the unmodified crate source — `cargo vendor`, or
`https://crates.io/api/v1/crates/acadrust/0.4.1/download`, or the upstream
commit above.
2. Apply [`public/licenses/acadrust-0.4.1-read_mesh.patch`](./public/licenses/acadrust-0.4.1-read_mesh.patch)
(`/licenses/acadrust-0.4.1-read_mesh.patch` on the deployed site):
```bash
tar xf acadrust-0.4.1.crate && cd acadrust-0.4.1
patch -p1 < acadrust-0.4.1-read_mesh.patch
```
The result is the exact Source Code Form of the acadrust code compiled into the
shipped `.wasm`. Both the original and the modified file remain under MPL-2.0.

2. License Grants and Conditions
--------------------------------
2.1. Grants
Each Contributor hereby grants You a world-wide, royalty-free,
non-exclusive license:
(a) under intellectual property rights (other than patent or trademark)
Licensable by such Contributor to use, reproduce, make available,
modify, display, perform, distribute, and otherwise exploit its
Contributions, either on an unmodified basis, with Modifications, or
as part of a Larger Work; and
(b) under Patent Claims of such Contributor to make, use, sell, offer
for sale, have made, import, and otherwise transfer either its
Contributions or its Contributor Version.
2.2. Effective Date
The licenses granted in Section 2.1 with respect to any Contribution
become effective for each Contribution on the date the Contributor first
distributes such Contribution.
2.3. Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights granted under
this License. No additional rights or licenses will be implied from the
distribution or licensing of Covered Software under this License.
Notwithstanding Section 2.1(b) above, no patent license is granted by a
Contributor:
(a) for any code that a Contributor has removed from Covered Software;
or
(b) for infringements caused by: (i) Your and any other third party's
modifications of Covered Software, or (ii) the combination of its
Contributions with other software (except as part of its Contributor
Version); or
(c) under Patent Claims infringed by Covered Software in the absence of
its Contributions.
This License does not grant any rights in the trademarks, service marks,
or logos of any Contributor (except as may be necessary to comply with
the notice requirements in Section 3.4).
2.4. Subsequent Licenses
No Contributor makes additional grants as a result of Your choice to
distribute the Covered Software under a subsequent version of this
License (see Section 10.2) or under the terms of a Secondary License (if
permitted under the terms of Section 3.3).
2.5. Representation
Each Contributor represents that the Contributor believes its
Contributions are its original creation(s) or it has sufficient rights
to grant the rights to its Contributions conveyed by this License.
2.6. Fair Use
This License is not intended to limit any rights You have under
applicable copyright doctrines of fair use, fair dealing, or other
equivalents.
2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
in Section 2.1.
3. Responsibilities
-------------------
3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
(a) such Covered Software must also be made available in Source Code
Form, as described in Section 3.1, and You must inform recipients of
the Executable Form how they can obtain a copy of such Source Code
Form by reasonable means in a timely manner, at a charge no more
than the cost of distribution to the recipient; and
(b) You may distribute such Executable Form under the terms of this
License, or sublicense it under different terms, provided that the
license for the Executable Form does not attempt to limit or alter
the recipients' rights in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).
3.4. Notices
You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.
4. Inability to Comply Due to Statute or Regulation
---------------------------------------------------
If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description must
be placed in a text file included with all distributions of the Covered
Software under the name "LEGAL", and included in all Covered Software
distributed in Source Code Form. Except to the extent prohibited by
statute or regulation, such description must be sufficiently detailed
for a recipient of ordinary skill to be able to understand it.
5. Termination
--------------
5.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a particular
Contributor are reinstated (a) provisionally, unless and until such
Contributor explicitly and finally terminates Your grants, and (b) on an
ongoing basis, if such Contributor fails to notify You of the
non-compliance by some reasonable means prior to 60 days after You have
come back into compliance. Moreover, Your grants from a particular
Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the
first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after
Your receipt of the notice.
5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.
5.3. In the event of termination under Sections 5.1 or 5.2 above, all
end user license agreements (excluding distributors and resellers) which
have been validly granted by You or Your distributors under this License
prior to termination shall survive termination.
************************************************************************
* *
* 6. Disclaimer of Warranty *
* ------------------------- *
* *
* Covered Software is provided under this License on an "as is" *
* basis, without warranty of any kind, either expressed, implied, or *
* statutory, including, without limitation, warranties that the *
* Covered Software is free of defects, merchantable, fit for a *
* particular purpose or non-infringing. The entire risk as to the *
* quality and performance of the Covered Software is with You. *
* Should any Covered Software prove defective in any respect, You *
* (not any Contributor) assume the cost of any necessary servicing, *
* repair, or correction. This disclaimer of warranty constitutes an *
* essential part of this License. No use of any Covered Software is *
* authorized under this License except under this disclaimer. *
* *
************************************************************************
************************************************************************
* *
* 7. Limitation of Liability *
* -------------------------- *
* *
* Under no circumstances and under no legal theory, whether tort *
* (including negligence), contract, or otherwise, shall any *
* Contributor, or anyone who distributes Covered Software as *
* permitted above, be liable to You for any direct, indirect, *
* special, incidental, or consequential damages of any character *
* including, without limitation, damages for lost profits, loss of *
* goodwill, work stoppage, computer failure or malfunction, or any *
* and all other commercial damages or losses, even if such party *
* shall have been informed of the possibility of such damages. This *
* limitation of liability shall not apply to liability for death or *
* personal injury resulting from such party's negligence to the *
* extent applicable law prohibits such limitation. Some *
* jurisdictions do not allow the exclusion or limitation of *
* incidental or consequential damages, so this exclusion and *
* limitation may not apply to You. *
* *
************************************************************************
8. Litigation
-------------
Any litigation relating to this License may be brought only in the
courts of a jurisdiction where the defendant maintains its principal
place of business and such litigation shall be governed by laws of that
jurisdiction, without reference to its conflict-of-law provisions.
Nothing in this Section shall prevent a party's ability to bring
cross-claims or counter-claims.
9. Miscellaneous
----------------
This License represents the complete agreement concerning the subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent
necessary to make it enforceable. Any law or regulation which provides
that the language of a contract shall be construed against the drafter
shall not be used to construe this License against a Contributor.
10. Versions of the License
---------------------------
10.1. New Versions
Mozilla Foundation is the license steward. Except as provided in Section
10.3, no one other than the license steward has the right to modify or
publish new versions of this License. Each version will be given a
distinguishing version number.
10.2. Effect of New Versions
You may distribute the Covered Software under the terms of the version
of the License under which You originally received the Covered Software,
or under the terms of any subsequent version published by the license
steward.
10.3. Modified Versions
If you create software not governed by this License, and you want to
create a new license for such software, you may create and use a
modified version of this License if you rename the license and remove
any references to the name of the license steward (except to note that
such modified license differs from this License).
10.4. Distributing Source Code Form that is Incompatible With Secondary
Licenses
If You choose to distribute Source Code Form that is Incompatible With
Secondary Licenses under the terms of this version of the License, the
notice described in Exhibit B of this License must be attached.
Exhibit A - Source Code Form License Notice
