**Summary**
In preparation for adding more tests related to image extraction,
improve the `partition_odt()` test suite:
- Add type annotations to type-check clean on strict mode.
- Improve test names.
- Simplify tests where possible.
- Remove a couple duplicated tests
### Summary
Updates the `Dockerfile` to use the Chainguard `wolfi-base` image to
reduce CVEs. Also adds a step in the docker publish job that scans the
images and checks for CVEs before publishing. The job will fail if there
are high or critical vulnerabilities.
### Testing
Run `make docker-run-dev` and then `python3.11` once you're in. And that
point, you can try:
```python
from unstructured.partition.auto import partition
elements = partition(filename="example-docs/DA-1p.pdf", skip_infer_table_types=["pdf"])
elements
```
Stop the container once you're done.
**Summary**
In preparation for adding more tests related to image extraction,
improve the `partition_doc()` test suite:
- Remove redundant DOCX -> DOC file conversions on most tests.
- Add type annotations to type-check clean on strict mode.
- Improve test names.
- Simplify tests where possible.
- Remove one duplicated test
Speed was roughly doubled: 24 tests in 20s -> 23 tests in 8s.
**Summary**
Organize DOC tests into related groups with markers. This makes it
easier to assess coverage and find tests related to particular
behaviors.
This is in preparation for adding tests related to DOC image extraction.
No code changes, purely line-block moves.
- Move module-level fixtures to the bottom.
- Organize tests into related groups with markers.
**Summary**
A crude and OS-specific mechanism was used to detect when a path
represented a temp-file. Change that to be robust across operating
systems and localized configurations. The specific problem was for DOC
files but this PR fixes it for PPT too which was prone to the same
problem.
Part two of: https://github.com/Unstructured-IO/unstructured/pull/2842
Main changes compared to part one:
* hash computation includes element's sequence number on page, page
number, document filename and its text
* there are more test for deterministic behavior of IDs returned by
partitioning functions + their uniqueness (guaranteed at the document
level, and high probability across multiple documents)
This PR addresses the following issue:
https://github.com/Unstructured-IO/unstructured/issues/2461
Introduce `date_from_file_object` to `partition*` functions, by default
set to `False`.
If set to `True` and file is provided via `file` parameter, partition
will attempt to infer last modified date from `file`'s contents
otherwise last modified metadata will be set to `None`.

*Reviewer:* May be quicker to review commit by commit as they are quite
distinct and well-groomed to each focus on a single clean-up task.
Clean up odds-and-ends in the docx partitioner in preparation for adding
nested-tables support in a closely following PR.
1. Remove obsolete TODOs now in GitHub issues, which is probably where
they belong in future anyway.
2. Remove local DOCX "workaround" code that has been implemented
upstream and is now obsolete.
3. "Clean" the docx tests, introducing strict typing, extracting a
fixture or two, and generally tightening things up.
4. Extract docx-local versions of
`unstructured.partition.common.convert_ms_office_table_to_text()` which
will be the base for adding nested-table support. More information on
why this is required in that commit.
Each partitioner has a test like `test_partition_x_with_json()`. What
these do is serialize the elements produced by the partitioner to JSON,
then read them back in from JSON and compare the before and after
elements.
Because our element equality (`Element.__eq__()`) is shallow, this
doesn't tell us a lot, but if we take it one more step, like
`List[Element] -> JSON -> List[Element] -> JSON` and then compare the
JSON, it gives us some confidence that the serialized elements can be
"re-hydrated" without losing any information.
This actually showed up a few problems, all in the
serialization/deserialization (serde) code that all elements share.
### Summary
Closes#1534 and #1535
Detects document language using `langdetect` package.
Creates new kwargs for user to set the document language (`languages`)
or detect the language at the element level instead of the default
document level (`detect_language_per_element`)

### Summary
Duplicate PR of #1259 because of issues with checks
Closes#1227, which found that `nan` values were present in the
coordinates being generated for some elements.
This breaks logic out from `add_pytesseract_bbox_to_elements` to new
functions `_get_element_box` and
`convert_multiple_coordinates_to_new_system`. It also updates the logic
to check that the current bounding box matches the first character of
the element's text (as to avoid the `~` characters that
`pytesseract.image_to_boxes` includes, but are not present in
`pytesseract.image_to_string`.
### Testing
```
from unstructured.partition.image import partition_image
from PIL import Image, ImageDraw
filename="example-docs/layout-parser-paper-with-table.jpg"
elements = partition_image(filename=filename, strategy="ocr_only")
image = Image.open(filename)
draw = ImageDraw.Draw(image)
for i, element in enumerate(elements):
print(i, element.metadata.coordinates)
if element.metadata.coordinates:
draw.polygon(element.metadata.coordinates.points, outline="red", width=2)
output = "example-docs/box-layout-parser-paper-with-table.jpg"
image.save(output)
image.close()
```

### Summary
Partial solution to #1185.
Related to #1222.
Creates decorator from `chunk_by_title` cleaning brick.
Breaks a document into sections based on the presence of Title elements.
Also starts a new section under the following conditions:
- If metadata changes, indicating a change in section or page or a
switch to processing attachments. If `multipage_sections=True`, sections
can span pages. `multipage_sections` defaults to True.
- If the length of the section exceeds `new_after_n_chars` characters.
The default is 1500. The **chunking function does not split individual
elements**, so it's possible for a section to exceed that threshold if
an individual element if over `new_after_n_chars characters`, which
could occur with a long NarrativeText element.
Combines sections under these conditions
- Sections under `combine_under_n_chars` characters are combined. The
default is 500.
### Testing
from unstructured.partition.html import partition_html
url = "https://understandingwar.org/backgrounder/russian-offensive-campaign-assessment-august-27-2023-0"
chunks = partition_html(url=url, chunking_strategy="by_title")
for chunk in chunks:
print(chunk)
print("\n\n" + "-"*80)
input()
Update `test_json` to not use auto partition due to dependencies. Previously, to run `test_json` requires full requirements installation library to read file types, including but not limited to, docx, pptx, as well as others. Therefore the test will raise error with base installation. With the update, this fix also add to other test files to check its invariant with `elements_to_json`.
**Summary**
Closes#747
* Create CI Pipeline for running text, xml, email, and html doc tests
against the library installed without extras
* Create CI Pipeline for running each library extra against their
respective tests
