为什么我在 Heroku 上使用 hypnotoad 会崩溃？
Why is my use of hypnotoad crashing on Heroku?
我正在尝试让 Mojolicious::Lite app running on Heroku with Perloku. There's something that doesn't happen when hypnotoad 进入其运行循环导致其崩溃的 hypnotoad。我想我遗漏了一些简单的东西，但 Heroku 文档没有帮助，我也无法从中提取好的错误消息。
我从一个非常简单的应用程序开始，所以显示一些环境变量：
#!/usr/bin/env perl
# today
use Mojolicious::Lite;
get '/' => sub {
my $c = shift;
my $content = "Perl: $^X Pid: $\n\n";
foreach my $key ( keys %ENV ) {
next unless $key =~ /Mojo|toad/i;
$content .= "$key $ENV{$key}\n";
}
$c->stash( content => $content );
$c->render('index');
};
app->start;

当我在本地运行时，没有问题。我从环境变量中看到我的程序是在hypnotoad下运行的：
Welcome to the Mojolicious real-time web framework!

现在，我用 Mojolicious::Command::deploy::heroku 部署它：
% toady deploy heroku --create
这是在 https://frozen-brushlands-4002.herokuapp.com 运行，使用默认的 Perloku 文件：
#!/bin/sh
./toady daemon --listen http://*:$PORT --mode production
尽管我看到一些参考资料说这是我应该得到的，但这并没有运行 hypnotoad。不过，该应用程序有效：

我想我可以更改 Perloku 文件来启动 hypnotoad:
#!/bin/sh
/app/vendor/perl/bin/perl /app/vendor/perl-deps/bin/hypnotoad toady
hypnotoad 启动并几乎立即关闭，没有其他日志消息：

我可以更改调用以使用 -t 来测试应用程序以查看是否：
#!/bin/sh
/app/vendor/perl/bin/perl /app/vendor/perl-deps/bin/hypnotoad -t toady
有效，我收到 "Everything looks good!" 消息，所以 hypnotoad 正在运行：

$log->debug( "Right before start" );
my $app = app->start;
$log->debug( "Right after start" );
$app; # must return application object
我尝试了其他方法，例如让它加载一个我知道不存在的模块，我在日志中得到了预期的 "Could not find" 错误。
从 heroku (heroku run bash) 中的 shell 运行并没有启发性。 mojo version 的输出与我本地机器上的输出相同：

You might want to update your Mojolicious to 5.72.
我想我遗漏了一些非常简单的东西，但与此同时，这些都不是为了便于调试而设计的。
奥列格靠得更近了一点，但还是有问题。我以前试过前台选项，也遇到了同样的问题，但没有提到。
如果我在前台启动 hypnotoad，它会尝试绑定到一个地址。绑定不了80（或443）端口就死机了，127.0.0.1: 几乎可以监听，但是貌似没有完全监听:

这真的只是一个大胆的猜测，但也许 heroku 基础设施不希望运行程序终止？如果是这样，您可以尝试使用 --foreground 或 -f.
启动 hypnotoad
此外，您可以尝试从应用程序内部进行一些日志记录，看看它是否曾经运行过它。
经过一些测试，我找到了在 heroku
上 运行 hypnotoad 的方法
1. Perloku 内容应如下所示
#!/bin/sh
perl /app/vendor/perl-deps/bin/hypnotoad -f mojocrashtest
描述
首先我们需要显式调用perl。因为
heroku run bash
head /app/vendor/perl-deps/bin/hypnotoad
显示
#!/tmp/perl/perls/perl-5.18.1/bin/perl
eval 'exec /tmp/perl/perls/perl-5.18.1/bin/perl -S [=12=] ${1+"$@"}'
if 0; # not running under some shell
其中 /tmp/perl/perls/perl-5.18.1/bin/perl 不存在。所以，/app/vendor/perl-deps/bin/hypnotoad不会启动，但是perl /app/vendor/perl-deps/bin/hypnotoad会好的。
然后正如@moritz 猜测的那样，我们需要 hypnotoad 的密钥 -f。否则 heroku 会认为您的应用程序意外完成。
2。你应该在端口 $ENV{PORT}
上启动 hypnotoad
对于 Mojolicious::Lite 你只需要在你的应用程序的顶部写这样的东西：
plugin Config => {default => {hypnotoad => {listen => ["http://*:$ENV{PORT}"]}}};
对于完整的应用程序，您可以在 startup 处理程序中完成。
3。 heroku 打开
这是 Mojolicious::Lite application 的完整代码
#!/usr/bin/env perl
# today
use Mojolicious::Lite;
plugin Config => {default => {hypnotoad => {listen => ["http://*:$ENV{PORT}"]}}};
get '/' => sub {
my $c = shift;
my $content = "Perl: $^X Pid: $$\n\n";
foreach my $key ( keys %ENV ) {
next unless $key =~ /Mojo|toad/i;
$content .= "$key $ENV{$key}\n";
}
$c->stash( content => $content );
$c->render('index');
};
app->start;

URL 对于我的应用：http://floating-temple-3676.herokuapp.com/
顺便说一句，我没有使用 mojo deploy，只是 git
，但假设中缺少一些部分。
首先，创建一个新的 heroku 应用程序并记住应用程序的名称：
$ heroku create
Creating vast-spire-6174... done, stack is cedar-14
https://vast-spire-6174.herokuapp.com/ | https://git.heroku.com/vast-spire-6174.git
接下来，添加 Perloku 构建包：
$ heroku config:add BUILDPACK_URL=https://github.com/judofyr/perloku.git
在 Heroku 上创建 git 存储库和设置：
$ mkdir testapp
$ cd testapp
$ git init
$ heroku git:remote -a vast-spire-6174
要使一切正常，您需要一个 Perloku 文件在前台启动 hypnotoad。您必须明确指定 perl，因为 hypnotoad 中的 shebang 行指的是 perl 构建时的临时位置以及不再存在的位置。将 myapp.pl 更改为您为应用程序命名的任何名称。
#!/bin/sh
/app/vendor/perl/bin/perl /app/vendor/perl-deps/bin/hypnotoad -f myapp.pl
要安装所有内容，请使用标准 Makefile.PL。将 Mojolicious 指定为先决条件之一：
use strict;
use warnings;
use ExtUtils::MakeMaker;
WriteMakefile(
VERSION => '0.01',
PREREQ_PM => {'Mojolicious' => '5.72'},
test => {TESTS => 't/*.t'}
);
最后，您可以使用 mojo 创建的应用程序本身（调用是 myapp.ppl）
$ mojo generate lite_app
这是生成的源代码：
#!/usr/bin/env perl
use Mojolicious::Lite;
# Documentation browser under "/perldoc"
plugin 'PODRenderer';
get '/' => sub {
my $c = shift;
$c->render('index');
};
app->start;

<body><%= content %></body>

您必须修改基本程序，因为 hypnotoad 需要一些配置（默认服务器不需要）：
#!/usr/bin/env perl
use Mojolicious::Lite;
# Documentation browser under "/perldoc"
plugin 'PODRenderer';
plugin Config => {
default => {
hypnotoad => {
listen => ["http://*:$ENV{PORT}"]
}
}
};

获得所有文件后，提交它们，然后推送到 heroku 分支。
$ git add .
$ git commit -am "make it better"
$ git push heroku master

这真的只是一个大胆的猜测，但也许 heroku 基础设施不希望运行程序终止？如果是这样，您可以尝试使用 --foreground 或 -f.
此外，您可以尝试从应用程序内部进行一些日志记录，看看它是否曾经运行过它。
经过一些测试，我找到了在 heroku
上 运行 hypnotoad 的方法1. Perloku 内容应如下所示
#!/bin/sh
perl /app/vendor/perl-deps/bin/hypnotoad -f mojocrashtest
描述
首先我们需要显式调用perl。因为
heroku run bash
head /app/vendor/perl-deps/bin/hypnotoad
显示
#!/tmp/perl/perls/perl-5.18.1/bin/perl
eval 'exec /tmp/perl/perls/perl-5.18.1/bin/perl -S [=12=] ${1+"$@"}'
if 0; # not running under some shell
其中 /tmp/perl/perls/perl-5.18.1/bin/perl 不存在。所以，/app/vendor/perl-deps/bin/hypnotoad不会启动，但是perl /app/vendor/perl-deps/bin/hypnotoad会好的。
然后正如@moritz 猜测的那样，我们需要 hypnotoad 的密钥 -f。否则 heroku 会认为您的应用程序意外完成。
2。你应该在端口 $ENV{PORT}
上启动 hypnotoad对于 Mojolicious::Lite 你只需要在你的应用程序的顶部写这样的东西：
plugin Config => {default => {hypnotoad => {listen => ["http://*:$ENV{PORT}"]}}};
对于完整的应用程序，您可以在 startup 处理程序中完成。
3。 heroku 打开
这是 Mojolicious::Lite application 的完整代码
#!/usr/bin/env perl
# today
use Mojolicious::Lite;
plugin Config => {default => {hypnotoad => {listen => ["http://*:$ENV{PORT}"]}}};
get '/' => sub {
my $c = shift;
my $content = "Perl: $^X Pid: $$\n\n";
foreach my $key ( keys %ENV ) {
next unless $key =~ /Mojo|toad/i;
$content .= "$key $ENV{$key}\n";
}
$c->stash( content => $content );
$c->render('index');
};
app->start;

URL 对于我的应用：http://floating-temple-3676.herokuapp.com/
顺便说一句，我没有使用 mojo deploy，只是 git
首先，创建一个新的 heroku 应用程序并记住应用程序的名称：
$ heroku create
Creating vast-spire-6174... done, stack is cedar-14
https://vast-spire-6174.herokuapp.com/ | https://git.heroku.com/vast-spire-6174.git
接下来，添加 Perloku 构建包：
$ heroku config:add BUILDPACK_URL=https://github.com/judofyr/perloku.git
在 Heroku 上创建 git 存储库和设置：
$ mkdir testapp
$ cd testapp
$ git init
$ heroku git:remote -a vast-spire-6174
要使一切正常，您需要一个 Perloku 文件在前台启动 hypnotoad。您必须明确指定 perl，因为 hypnotoad 中的 shebang 行指的是 perl 构建时的临时位置以及不再存在的位置。将 myapp.pl 更改为您为应用程序命名的任何名称。
#!/bin/sh
/app/vendor/perl/bin/perl /app/vendor/perl-deps/bin/hypnotoad -f myapp.pl
要安装所有内容，请使用标准 Makefile.PL。将 Mojolicious 指定为先决条件之一：
use strict;
use warnings;
use ExtUtils::MakeMaker;
WriteMakefile(
VERSION => '0.01',
PREREQ_PM => {'Mojolicious' => '5.72'},
test => {TESTS => 't/*.t'}
);
最后，您可以使用 mojo 创建的应用程序本身（调用是 myapp.ppl）
$ mojo generate lite_app
这是生成的源代码：
#!/usr/bin/env perl
use Mojolicious::Lite;
# Documentation browser under "/perldoc"
plugin 'PODRenderer';
get '/' => sub {
my $c = shift;
$c->render('index');
};
app->start;

@@ layouts/default.html.ep
<!DOCTYPE html>
<html>
<head><title><%= title %></title></head>
<body><%= content %></body>
</html>
您必须修改基本程序，因为 hypnotoad 需要一些配置（默认服务器不需要）：
#!/usr/bin/env perl
use Mojolicious::Lite;
# Documentation browser under "/perldoc"
plugin 'PODRenderer';
plugin Config => {
default => {
hypnotoad => {
listen => ["http://*:$ENV{PORT}"]
}
}
};
get '/' => sub {
my $c = shift;
$c->render('index');
};
app->start;
__DATA__

@@ layouts/default.html.ep

<body><%= content %></body>
</html>
获得所有文件后，提交它们，然后推送到 heroku 分支。
$ git add .
$ git commit -am "make it better"
$ git push heroku master
当你推动时，一个钩子将启动一切。

为什么这在我不知道之前对我有用。我让一个 mojo 命令为我部署，所以那里可能有一些东西需要调查。但是，在没有中介的情况下提交和推送会更容易一些。
