doc.saveIncr() error and doc.close error about pymupdf HOT 2 CLOSED

Incremental saves are not always possible: a number of situations will prevent this. Instead of trying / excepting you can check doc.can_save_incrementally() and only do an incremental save if True is returned.
The following script works flawlessly:

import pymupdf as fitz
doc=fitz.open("1.-.Copy.pdf")
doc.can_save_incrementally()
1
doc.is_repaired
False
for page in doc:
    _=page.get_text()
    print(f"Processed {page.number=}")

    
MuPDF error: format error: object (44 0 R) was not found in its object stream
MuPDF error: format error: object (35 0 R) was not found in its object stream
Processed page.number=0
Processed page.number=1
Processed page.number=2
Processed page.number=3
Processed page.number=4
Processed page.number=5
Processed page.number=6
Processed page.number=7
doc.is_repaired
True
doc.can_save_incrementally()
0
doc.ez_save("temp.pdf")
doc.close()
import os
os.remove(doc.name)

After a failing incremental save, obviously an additional reference count is added to the file handle which is not removed on closing the document. This happens on Windows only - no problem on Linux at least.

We will look into this. In the meantime, please use doc = None or del doc after closing. This will triger an additional reference count reduction and the removal will succeed.

many thanks! As you did again the beginning, doc.can_save_incrementally() is 1 before get_text(), just not realize the get_text() will cause "repair" and doc.can_save_incrementally() = false. Will check again before every saveIncr in the future.
