Porting from old version (1.21) to pymupdf to 1.24.14

[PCarle]

each time i use reload_page i have :
Traceback (most recent call last):
....
File "C:\Anaconda3\envs\Python39PySide2PyMupdfNew\lib\site-packages\pymupdf_init_.py", line 5418, in reload_page
assert m_internal_new != m_internal_old,
AssertionError: refs_old=4 m_internal_old=0x16bb1e95ca0 m_internal_new=0x16bb1e95ca0

i certainly do somthing wrong ! in with case reload_page assertion is fired?

thank's in advance for help

Please upload the document you're using and your Python code. Otherwise it's not possible to know what's going wrong.

just simple code as exemple on my problem :
i need reload_page for preserve text annotation resizing (see the 2 text annotations one followed by a reload and second followed bay polygon annotation creation and updated)

when i change somes properties on annotations in page , after that reload_page (last one) crash !

thank's in advance for explainatiçon on rugth use !

if i change get_pannots defintion to :

def get_pannots(p):
    res= []
    for a in page.annots():
        tmp=a.info
        if 'subject' in tmp:
            if "toto"==tmp['subject']:
                if (a.type[0]==mupdf.PDF_ANNOT_POLYGON ):
                    #print("findPolyAnnotationsInPage",tmp['id'])
                    res.insert(-1,a)
        
    return res

No errors ! !

I'm glad you've got thnig working. But could you still upload test_text_annot.pdf to this issue so i can have a look at what was going wrong?

[PCarle]

The PDF file is generated by the script.

i things the assert is not correct in fact if refs number > 1 it must be the same page to reload (asser old == new ) i'm wrong ?
