Docs / Instructions

• https://github.com/cgoldberg/multi-mechanize/blob/master/docs/README.rst

Install / Setup

Multi-Mechanize can be installed from PyPI using pip:

pip install multi-mechanize

... or download the source distribution from PyPI, unarchive, and run:

python setup.py install

... then use multimech-newproject and multimech-run to create and run your performance test projects.

Detailed Install / Setup

These instructions are for Debian/Ubuntu Linux. For other platforms, the setup is generally the same, with the exeption of installing system dependencies.

system-wide install

• install dependencies on Debian/Ubuntu:

  $ sudo apt-get install python-pip python-matplotlib
  

• install multi-mechanize from PyPI using Pip:

  $ sudo pip install -U multi-mechanize
  

• create a new project:

  $ multimech-newproject my_project
  

• run a project:

  $ multimech-run my_project
  

virtualenv + pip install (with matplotlib system package)

• install dependencies on Debian/Ubuntu:

  $ sudo apt-get install python-virtualenv python-matplotlib
  

• install multi-mechanize from PyPI in a virtualenv:

  $ virtualenv --system-site-packages ENV
  $ cd ENV
  $ source bin/activate
  (ENV)$ pip install multi-mechanize
  

virtualenv + pip install (with --no-site-packages)

• install dependencies on Debian/Ubuntu:

  $ sudo apt-get install build-essential libfreetype6-dev libpng-dev
  $ sudo apt-get install python-dev python-virtualenv
  

• install multi-mechanize and matplotlib from PyPI in a virtualenv:

  $ virtualenv ENV
  $ cd ENV
  $ source bin/activate
  (ENV)$ pip install multi-mechanize
  (ENV)$ pip install matplotlib
  

pip install latest dev branch from git repo

pip install -e git+http://github.com/cgoldberg/multi-mechanize.git#egg=multimechanize

multi-mechanize's Issues

Wrong number of threads

Consider following config:

[group0]
threads=100
script=group0.py

[group1]
threads=1
script=group1.py

MM will say that there are 3 threads, but actually threre are 101 threads. I think the problem is here: https://github.com/cgoldberg/multi-mechanize/blob/master/multimechanize/utilities/run.py#L107 . Will you accept patch that fixes this?

Traceback output while running

I got a traceback just in the middle of running the tests:

multimech-run v1.2.0 does not work under Windows

Multi-mechanize does currently not work under Windows when multimech-run MY_PROJECT is used.
The same project runs fine under UNIX/MACOSX.

The problem appears in the Agent.run() method where the script Transaction should be created.
The real problem seems to be related w/ the multiprocessing package under Windows and/or the way how exec()/eval() is used.
The imported scripts (modules), that are imported in the multimech.core.init() part of the parent process,
are no longer present in the globals of the forked UserGroup process that tries to create and start the Agent threads.

Also note that the exec()/eval() logic mentioned above worked fine in the past w/ multi-mechanize 1.010, Python 2.5 and manually installed multiprocessing package on the Windows platform. But it does no longer work w/ the built-in multiprocessing package when Python 2.6 is used.

NOTE:
The exec()/eval() semantic that is currently used should be replaced w/ import-logic (IMHO) in a script_loader module.
But this also does not solve the problem from above (I tried it).

VERSION-INFO:

• Windows XP SP3
• Python 2.6.6
• multi-mechanize 1.2.0

Wrong couting

[user_group-reader6]
threads = 250
script = cms_reader.py

[user_group-reader5]
threads = 250
script = cms_reader.py

[user_group-reader4]
threads = 250
script = cms_reader.py

[user_group-reader3]
threads = 250
script = cms_reader.py

[user_group-reader2]
threads = 250
script = cms_reader.py

[user_group-reader1]
threads = 250
script = cms_reader.py

[user_group-writer]
threads = 10
script = cms_writer.py

When i start the test i get the following output.

user_groups: 7
threads: 70

[ 1% ] 223s/36000s transactions: 29 timers: 29 errors: 0

but 70 threads is not correct.

Create transaction object with params defined in general config

For example, scripts are sending request to http://www.xyz.zxy?xxx=any_phrase on develop environment and any outher address on product environment. My url include any words from huge file so i cant add it to git repo. The file is preset on product environment but not the same place like develop environment. To change the addresses an intervention in the test scripts is required so, set all path in to config file will useful but now it is impossible.

Solution is rebuild "configure" method from utilities/run.py. This method need to read more params like args=[] or somethig like that. Methods "run" from core.UserGroup and core.Agent must take one more argument and core.Agent need to create transaction object with this one param.

Issue with directory creation on Windows

In issue #4 @bgoldfedder mentioned a problem with creating directories:

The issue on makedir failing is if there are multiple user-groups in the config
That said, still having problems running on windows. It just makes lots of results_ directories....

I think this may have to do with the way output directories are defined using some strings with hardcoded / forward slashes.

Website URL not working

The recommended URL for the documentation (http://multimechanize.com) doesn't actually lead anywhere. It just redirects back to the author's Github page. Is there an alternate location where there is starter documentation?

'NoneType' object has no attribute 'Empty'

I get these errors (not all the time):

Exception in thread Thread-1 (most likely raised during interpreter shutdown):
Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 551, in __bootstrap_inner
File "/opt/virtenvs/django_slice/src/multimechanize/multimechanize/resultswriter.py", line 51, in run
<type 'exceptions.AttributeError'>: 'NoneType' object has no attribute 'Empty'

The config is the default config that is created with a new project.
[global]
run_time = 30
rampup = 0
results_ts_interval = 10
progress_bar = on
console_logging = off
xml_report = off

[user_group-1]
threads = 3
script = v_user.py

[user_group-2]
threads = 3
script = v_user.py

Create settings file

What do you think about creating a settings.py that handles the reading and parsing of the config file? I think it would be nice to separate that logic into another location and allow it to be used anywhere by any of the other files. An example of this would be:

from multimechanize.settings import configure
config = configure(config_file)

That could then return a config object with the following:

config.run_time
config.rampup
config.restuls_ts_interval
config.console_logging
config.progress_bar
config.results_database
config.post_run_script
config.xml_report
config.user_group_configs

A separate file would also give us a place to put any configuration-related utility methods.

Project Dead?

Is this project no longer being maintained? Is there an alternative?

multimech-run causes infinite loop

When I use multimech-run my_project I see unending stream of console output printing the number of user groups and threads. I am running on Python 2.7 32bit on Win 7 64bit.

I added the following code to the start of run.py to perform some inspection about the caller.
frm = inspect.stack()[1]
mod = inspect.getmodule(frm[0])
print frm

list index out of range when writing results

There are a few situations that lead to the results.py hitting a list index out of range. It can be easily produced by just setting the run_time in the examples/config.cfg time to 1 second and this will trigger the issue. I tried figuring out exactly why it was happening but was unable to diagnose the issue quickly so I came up with an easy to reproduce scenario to hopefully have this figured out as it actually affects a different scenario that I've developed for work.
