gpg: Encrypting lots of files with --multiple gets failed: Too many open files
Closed, ResolvedPublic
Actions

Description

Here is the error:

$ gpg --no-permission-warning --homedir A_HOMEDIR --recipient A_RECIPIENT --multifile --encrypt <A_FILE_CONTAINING_THOUSANDS_OF_FILENAMES
gpg: encryption of 'A_FILENAME' failed: Too many open files

Translation: ask gpg to encrypt thousands of files by using --multiple
and feeding them from stdin, and gpg runs out of file handles.
Evidently someone didn't close() the input file.

This occurred on Debian stretch, version 2.1.18. Same thing happens with 2.2.5. It didn't happen on Debian Jessie, 2.0.26.

I assume -z0 could be used as a workaround but without compression then.
Fix goes into 2.2.7 to be release tomorrow (tm)
