mod_mruby's Issues

It's very nice!!

Implement extended library which was written by IIJ to mod_mruby.

Implement a mehtod of connecting external db.

I want to implement a method of connecting external db like redis.

refs: http://6pongi.wordpress.com/2012/08/12/hiredis/

sample

r = Apache::Redis.new(ip, port)
r.set(key, value)
r.get(key)

Receive empty body on another module when read request body by mruby script.

Hi,
I am using Request.body to read POST request on my logging script (like below),
request body is being read properly at script, but another module (mod_proxy in my case)
receive empty body.

r = Apache::Request.new

if r.method_number == Apache::M_POST and r.uri == '/login'
  File.open('path/of/login/log/file', 'a') do |f|
    # mask password
    bodyMasked = r.body.gsub(/password=[^&]*/, 'password=xxx')
    # write body
    f.write("#{bodyMasked}\n")
  end
end

In my opinion, this problem is caused by ap_get_client_block() method (used by ap_mrb_get_request_body() for read request body).
(ref., http://www.gossamer-threads.com/lists/apache/dev/381941)

Is this behavior correct? or bug?

LOG_EMERG duplicate definition

LOG_EMERG is defined twice in ap_mrb_core.c.

https://github.com/matsumoto-r/mod_mruby/blob/master/src/ap_mrb_core.c#L253
https://github.com/matsumoto-r/mod_mruby/blob/master/src/ap_mrb_core.c#L257

I just found it with code inspection, not sure if it might be a real problem.

Support current mruby which removed mrb->irep

Current mruby removed mrb->irep.

Compile error on CentOS 6

I don't know if this is really an issue, but CentOS 6's GCC 4.4.7 cannot compile mod_mruby. Following patch worked:

Add input filter directive

Directive

<Directory /path/to/dir>
  SetInputFilter mruby
  mrubyInputFilter /path/to/input_filter.rb
</Directory>

input_filter.rb example

f = Apache::Filter.new

data = f.flatten
f.cleanup

f.insert_tail data
f.insert_tail "\n__mod_mruby_tail__"
f.insert_head "__mod_mruby_head__\n"
f.insert_eos

Implement bucket and bridgage.

implement bucket and bridgage.

Implement Web interface of Apache tunings and resource management.

Implement Web interface of Apache tunings and resource management. mod_mruby can control between Web interface and Apache without reload.

Coding by Ruby on Rails or mruby?

Support multi path per directive

I want to support multi path per directive like the following example:

<Location />
  mrubyHandlerMiddleMulti /path/to/A.rb /path/to/B.rb /path/to/C.rb
</Location>

First, mod_mruby run A.rb. Then run B.rb, Finally run C.rb at mrubyHandlerMiddle phase.

Support current mruby which renamed mrb_intern2

We should support current mruby which renamed mrb_intern2.

We should support test

Now, mod_mruby dosen't support test. We should support test and CI like Travis CI.

begin/ensure variable scope incorrect?

if I execute the following code with mruby:

strX = 'some no foo'
begin
	y='start'
	puts y
	foo
rescue => excp
	strX = 'some foo error'
ensure
	puts strX
	puts 'end'
end
return

I get the output:

start
some foo error
end

Without the error line ( comment out 'foo') it's:
start
some no foo
end

In mod_mruby the scope of a variable is not carried into the ensure:

strX = 'some no foo'
begin
	y='start'
	Apache.echo y
	foo
rescue => excp
	strX = 'some foo error'
ensure
	Apache.echo strX
	Apache.echo 'end'
end
return

Output from this is:

start

end

The variable seen by the ensure is set to nil (tested by getting an error if you attempt " strX += 'more text' " or some other manipulation of the nil value string). This could be intentional, but I wanted to be sure that this was working as designed or a problem.

Build fail. './mruby/build/host/mrblib/mrblib.o: could not read symbols: Bad value'

I would like to create a recipe of the opscode chef for mod_mruby.
Current working branch is https://github.com/higanworks-cookbooks/mruby/tree/mod_mruby.

But, build fails on vm.

Steps will reproduce the problem.

Add input filter directive

Directive

<Directory /path/to/dir>
  SetInputFilter mruby
  mrubyInputFilter /path/to/input_filter.rb
</Directory>

input_filter.rb example

f = Apache::Filter.new

data = f.flatten
f.cleanup

f.insert_tail data
f.insert_tail "\n__mod_mruby_tail__"
f.insert_head "__mod_mruby_head__\n"
f.insert_eos

Allow rb files to #include other rb files

Since we are already interpreting these rb files on the fly for every request, it would be very handy to have a simple way to include one file into another. An example of how this could look is:

#include foo
#include bar

foo = Foo.new
Apache.rputs foo.something(Bar)
Apache.return(Apache::OK)

This would presumably include foo.rb and bar.rb into this file before passing it to the mrb interpreter.

I have a very naive C program that will concatenate files into a tempfile based on #include statements at the very top: https://gist.github.com/myobie/4b0ee69c123f250c827f

I was not able to get the same code working in mod_mruby.c (segmentation fault 11 is my new friend), but I think the sample code helps explain my idea. For simplicity, I decided that the #include lines must appear on the first lines of a file.

Either way, this is the best I can do with C code right now. If I find a way to get my code actually working on a branch in mod_mruby, I will update this issue.

Change server config to dir config

Now mrubyHandlerMiddle or mrubyHandlerCodeMiddle and so on are server directive. The server directive can not work in directive. So we should change the server directive to dir directive.
