fitz.open() - Python keeps file open

[gosforth]

Hi,
I open pdf file:
doc = fitz.open(pfile)
At the end I close it
doc.close()
And I check if is closed:
isclosed = doc.is_closed
But another process says this file is kept by Python.
In previous version that worked fine.

How can I open this file only for reading?

EDIT
I've just came back to version 1.18.19 and that work well. Bug?

[JorjMcKie]

that is a problem in the current version
fixed in next v1.19.5

Thanks a lot for your help.
Concerning my philosophical question above? Use 'with' or clean up after myself? :-)
Is there option to open file only for reading?

[JorjMcKie]

one of the reasons for the issue in v1.19.4 was the effort to unify all the different Document destruction places.
Then I forgot that the C reference counter specifically for documents maybe > 1. So I had to build in (again) a loop that drops the document while any references exist.
So in short: starting v1.19.5 that makes no difference any more. You also can use doc = None or del doc with the same effect.

You could have asked earlier - others have no such inhibitions 😉 If you have Linux or Mac OSX, you will find current pre-version wheels here. If Windows drop me a note.

I have this problem on Windows.

I have another question about fitz.open() with html.
I use flask to develop a web app.
<input style="height:50px;width:600px;font-size:20px;" type="file" id="file" size="30" name="file" accept="application/pdf" multiple

files = request.files.getlist("file")
fitz.open can't open file in files. , fitz can't read the path html get. But pdfplumber can open this path.
Why fitz limit this ?

[JorjMcKie]

Your code is minimal and I am not sure where the files really exist you want to open.
But maybe this is an explanation:
To open a document with PyMuPDF, then this must either be a file existing on local drives, or it must be a memory area in formta of the respective document.
PyMuPDF does not access the internet as part of fitz.open(). You must first download any internet-resident file e.g., to a memory area (not necessarily to disk).
That maybe explains it.

https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file

with this element, fitz can't open selected files directly.

with this element, fitz can't open selected files directly.

That is because it is embedded in a HTML prompt.
