Plack::Runner watched for non-existing directories (watch/autorestart does not work)

[tomas-zemres]

If I run my webapp in terminal: starman $args -R /myapp/perllib /myapp/bin/app.psgi

It says:

!! Using restarter with -r or -R options is known to cause issues with process supervisor
!! such as start_server, and it is STRONGLY discouraged to use with Starman. You have been warned.
!!
Watching /myapp/perllib /myapp/bin/lib /myapp/bin/app.psgi for file updates.
watch failed: No such file or directory at /opt/perl-5.26.1/lib/site_perl/5.26.1/Plack/Loader/Restarter.pm line 79.

There is reported error "No such file or directory" (there is missing filename, due to another bug - https://github.com/miyagawa/Filesys-Notify-Simple/issues/26), but missing filename is "/myapp/bin/lib"

But directory "/myapp/bin/lib" does not exist in my project.

Plack::Runner calls watch(...) on non-existing directory: https://github.com/plack/Plack/blob/master/lib/Plack/Runner.pm#L178 $self->loader->watch( File::Basename::dirname($psgi) . "/lib", $psgi );

"Auto-restart" is not working in this case also for other watched directories after argument "-R"

I have a same problem.（ここ日本語で書いていいのかな…google翻訳英語ですみません）

Startup command plackup /var/www/root_dir/script/index.psgi -s Starlet -R /var/www/root_dir/conf/,/var/www/root_dir/lib/

Error occurred (The child process is repeatedly generated until the server is stopped) Watching /var/www/root_dir/conf/ /var/www/root_dir/lib/ /var/www/root_dir/script/lib /var/www/root_dir/script/index.psgi for file updates. watch failed: そのようなファイルやディレクトリはありません at /usr/local/share/perl5/Plack/Loader/Restarter.pm line 79.

In my environment, there is no lib directory under directory(/var/www/root_dir/script) of *.psgi.

In my environment there is no problem with $ Plack :: VERSION = 1.0044, After that my environment has been rebuilt(including OS) to 1.0047, an error has come to be issued. The contents of Runner.pm look the same. As a first aid, I created the lib directory under the script directory. The server is working without problems. （1.0044では問題なく動いていましたが、OSごと再構築したついでに1.0047にバージョンアップしてからエラーが発生するようになりました。Ruuner.pmの問題の箇所は同じに見えます。script下にlibを作ったら動いたので、それを応急処置としてます）

A pull request was present before this report. I found just now. Perhaps I think this issue will be fixed.

i made a temporary fix by reverting the breaking change (https://github.com/miyagawa/Filesys-Notify-Simple/pull/21) in Filesys::Notify::Simple in 0.14
