partition_pdf fails on an open binary file handle: fixed by PR 3395

Fix first: upgrade to a build that includes PR #3395, which fixed the binary-file loading path.

partition_pdf throws when passed an already-opened binary file handle (hi_res strategy)

1. Upgrade unstructured to a build containing PR #3395.
2. Retry partitionpdf with the open binary handle and the hires strategy. Expected: it partitions instead of throwing.

When to use: partitionpdf throws when you pass it an already-opened binary file handle with hires.

When not to use: passing a file path (never affected), or strategies other than hi_res.

Compatibility: unstructured, hi_res strategy. Reported in Unstructured-IO/unstructured#3097, fixed by PR #3395.

Variants:

• "partition_pdf open file handle"
• "partitionpdf hires binary handle"
• "unstructured partition_pdf throws file handle"

Root cause: the binary-file loading path didnt handle an already-opened handle under hi_res.

Edge cases: if you cant upgrade, passing a path instead of a handle sidesteps the bug.

In gh:Unstructured-IO/unstructured#3097, the issue was: Unable to load file. When using partitionpdf in the context of a binary file opened with open('./that.pdf', 'rb'), an error is thrown with strategy='hires'. Possibly related to issue #3076.. The verified answer: If partitionpdf throws when you pass it an already-opened binary file handle with the hires strategy, upgrade to a build that includes PR #3395, which fixed the binary-file loading path..
