Subject: [PATCH 04/82] inboxidle: new class to detect inbox changes
Date: Wed, 10 Jun 2020 07:04:01 +0000	[thread overview]
Message-ID: <20200610070519.18252-5-e@yhbt.net> (raw)
In-Reply-To: <20200610070519.18252-1-e@yhbt.net>

This will be used to implement IMAP IDLE, first.

Eventually, it may be used to trigger other things:

* incremental internal updates for manifest.js.gz
* restart `git cat-file' processes on pack index unlink
* IMAP IDLE-like long-polling HTTP endpoint

And maybe more things we haven't thought of, yet.

It uses Linux::Inotify2 or IO::KQueue depending on what packages
are installed and what the kernel supports.  It falls back to
nanosecond-aware Time::HiRes::stat() (available with Perl 5.10.0+)
on systems lacking Linux::Inotify2 and IO::KQueue.

In the future, a pure Perl alternative to Linux::Inotify2 may be
supplied for users of architectures we already support signalfd
and epoll on.

v2 changes:
- avoid O_TRUNC on lock file
- change ctime on Linux systems w/o inotify
- fix naming of comments and fields
