The report is correct. The c-client library makes no attempt to use the 64bit system calls; and thus flat files are limited to 2GB.

The recommended solution for mailboxes with aggregate size greater than 2GB is to use mix format instead of a flat file format. Even if c-client were updated to use the 64bit system calls, flat files (especially in traditional UNIX format) do not perform well at multi-GB sizes.

If there is some compelling reason offered, I will consider 64bit support. However, as of right now, I am highly skeptical that the benefit would be worth the effort, especially since there is a superior solution for large mailboxes available now ("superior" since it will always work better than a large flat file).

I'm forwarding this Debian user's bug report to the alpine-info list.

Is this a known issue in Alpine? I imagine it is a c-client issue; is it a known issue there?

The "LFS" tag in the Debian bug means that this issue relates to large file support.

If possible, please reply to all so that the Debian bug can pick up on any conversation here.

Subject: Bug#478545: [alpine] alpine does not support large (>2 GiB) mbox's

Package: alpine
Severity: normal
Tags: lfs

--- Please enter the report below this line. ---

If you attempt to open a mailbox that is over 2 GiB in size, alpine will refuse to open it, stating 'Folder "INBOX" opened with 0 messages' Pine 4.64 had the same behaviour previously.
