Created attachment 1419 [details] A patch to claws-mail to use gpgme_data_new_from_filepart() instead of gpgme_data_new_from_file(). (I didn't see a Plugins/PGPCore option, hopefully Plugins/Privacy is correct enough.) The code in src/plugins/pgpcore/sgpgme.c creates a tmpfile to populate the gpgme_data_t variable. The function currently being called is: gpgme_data_new_from_file(). The mime data already contains the e-mail file and the relevant mime coordinates, so why not just use the function gpgme_data_new_from_filepart()? Creating a tmpfile seems unneccessary and wastefull. Especially when one runs off a flashdisk that has a limited number of writes! Or perhaps on a read-only filesystem, when one needs to check e-mails but not download any new ones?
Thanks! Now applied!
Created attachment 1420 [details] Fixed version where file pointer is correctly closed I just noticed that the file pointer wasn't properly closed after my changes. The code that I removed included the closing of fp (which is the original file and not the temporary file). That file was opened at the start of the function.
