I am creating a file in /tmp; say /tmp/x.docx. After that using pypandoc I transform it into /tmp/x.pdf
This works perfectly, but:
… and there is no os.remove( ) in my code.
Where are my files stored ?
I know there exist temporary files in Django, which may be is a better solution than writing in /tmp, but I would like to understand…

Please post the actual code involved with creating and returning the file. Also describe your deployment environment in more detail. (e.g. Is anything like docker involved here?) I’d guess (with no other information yet) that what you think is the root isn’t the root for your process.
Ok.
Docker : no
Just running Django with apache2 and wsgi.
My code:
hee,
-ff is something like “xxx.odt”
-exten is: “odt”
-to is “md” or “pdf”

ust running Django with apache2 and wsgi.
My code:
here,
-ff is something like “xxx.odt”
-exten is: “odt”
-to is “md” or “pdf”
with open(“/tmp/”+ff, ‘wb+’) as destination:
for chunk in ff.chunks():
destination.write(chunk)
dest=ff.replace(exten,to)
pypandoc.convert_file("/tmp/"+ff, to,outputfile="/tmp/"+dest)
Above, pypandoc reads from “/tmp/”+ff and writes to “/tmp/”+dest.
Then:
with open(“/tmp/”+dest,“rb”) as fh:
response = HttpResponse(fh.read(),
content_type=‘application/’+to)
response[‘Content-Disposition’] = ‘inline;filename=/tmp/’+dest
return response
That’s all. It works perfectly.

And you’re running this code in a Django view?
Also, you mentioned:
Are you not seeing any files? Or just not seeing the file you’re looking for?
(If you’re not seeing any files, then it’s possible that the account you’re using doesn’t have permissions to see the files there.)
You can also use the find command to help find where the file is located.

Yes
Also, you mentioned:
Thierry-Dumont: I cannot see (ls /tmp) the files in /tmpAre you not seeing /any/ files? Or just not seeing the file you’re
looking for?
No, I see all the files in /tmp (as any Unix user can do)

hi 
just to be sure, you didn’t reboot or shutdown your system? anything in /tmp will be deleted once your system goes down

No.
This morning (it’s 5 pm here) I changed my code, using
NamedTemporaryFile’s , which is
certainly more "Django’ish).
If you create a NamedTemporaryFile, say by:
destination = NamedTemporaryFile(delete=True, suffix=“.”+exten,
prefix=pref)
you can do:
print(destination.name)
and what you get is something like: /tmp/
This /tmp directory is certainly not the Linux /tmp one, but (I think)
some pseudo-directory stored in the ram (like /tmp in modern Linux, but
not the same).
So I wonder if, when you open a file in /tmp using
with open(something,“wb”) as f:
…
you create it in this in memory directory or not.
It’s just an idea.

Look for a directory named '/tmp/systemd-private-(some long identifier)-apache2.service-(another identifier)/tmp` and search for your files in it.
If your system isn’t running systemd, look for any directory within /tmp with apache2 as part of its name.

Great !
(I am in debian trixie, so it is systemd)
My files are in:
/tmp/systemd-private-acd7116ad20147449b1f90eaafaa2da4-apache2.service-n4SVt5/tmp/
Problem was solved !
Thanks again.
