Codespeed
Codespeed is a web application to monitor and analyze the performance of your code.
Known to be used by CPython, PyPy, Twisted and others.
For an overview of some application concepts see the wiki page
Installation
You will need Python 2.7 or 3.5+.
To install dependencies and the codespeed Django app:
pip install codespeed
If you want version control integration, there are additional requirements:
- Subversion needs pysvn:
python-svn
- Mercurial needs the package
mercurial
to clone the repo locally - git needs the
git
package to clone the repo - For Github the isodate package is required, but not git:
pip install isodate
Note: For git or mercurial repos, the first time the changes view is accessed, Codespeed will try to clone the repo, which depending on the size of the project can take a long time. Please be patient.
- Download the last stable release from
github.com/tobami/codespeed/tags, unpack it and install it with
python setup.py install
. - To get started, you can use the
sample_project
directory as a starting point for your Django project, which can be normally configured by editingsample_project/settings.py
. - For simplicity, you can use the default sqlite configuration, which will save
the data to a database named
data.db
-
Create the DB by typing from the root directory:
python manage.py migrate
-
Create an admin user:
python manage.py createsuperuser
-
For testing purposes, you can now start the development server:
python manage.py runserver 8000
The codespeed installation can now be accessed by navigating to http://localhost:8000/
.
Note: for production, you should configure a real server like Apache or nginx (refer to the Django docs). You should also
modify sample_project/settings.py
and set DEBUG = False
.
sample_project/README.md
also describes some production settings.
Codespeed configuration
Using the provided test data
If you want to test drive Codespeed, you can use the testdata.json fixtures to have a working data set to browse.
- From the root directory, type:
./manage.py loaddata codespeed/fixtures/testdata.json
Starting from scratch
Before you can start saving (and displaying) data, you need to first create an environment and define a default project.
- Go to
http://localhost:8000/admin/codespeed/environment/
and create an environment. - Go to
http://localhost:8000/admin/codespeed/project/
and create a project.
Check the field "Track changes" and, in case you want version control integration, configure the relevant fields.
Note: Only executables associated to projects with a checked "track changes" field will be shown in the Changes and Timeline views.
Note: Git and Mercurial need to locally clone the repository. That means that your sample_project/repos
directory will need to be owned by the server. In the case of a typical Apache installation, you'll need to type sudo chown www-data:www-data sample_project/repos
Saving data
Data is saved POSTing to http://localhost:8000/result/add/
.
You can use the script tools/save_single_result.py
as a guide.
When saving large quantities of data, it is recommended to use the JSON API instead:
http://localhost:8000/result/add/json/
An example script is located at tools/save_multiple_results.py
Note: If the given executable, benchmark, project, or revision do not yet exist, they will be automatically created, together with the actual result entry. The only model which won't be created automatically is the environment. It must always exist or the data won't be saved (that is the reason it is described as a necessary step in the previous "Codespeed configuration" section).
Further customization
Custom Settings
You may override any of the default settings by setting them in
sample_project/settings.py
. It is strongly recommended that you only override the
settings you need by importing the default settings and replacing only the
values needed for your customizations:
from codespeed.settings import *
DEF_ENVIRONMENT = "Dual Core 64 bits"
Site-wide Changes
All pages inherit from the base.html
template. To change every page on the site
simply edit (sample_project/templates/codespeed/base_site.html
) and override
the appropriate block:
-
Custom title: you may replace the default "My Speed Center" for the title block with your prefered value:
{% block title %} My Project's Speed Center {% endblock %}
-
Replacing logo.png: Place your logo in
sample_project/static/images/logo.png
- Logo with custom filename: Place your logo in
sample_project/static/images/
and add a block like this tobase_site.html
:{% block logo %} <img src="{{ MEDIA_URL }}images/my-logo.jpg" width="120" height="48" alt="My Project"> {% endblock logo %}
n.b. the layout will stay exactly the same for any image with a height of 48px (any width will do)
- Custom JavaScript or CSS: add your files to the
sample_project/static/js
directory and extend theextra_head
template block:{% block extra_head %} {{ block.super }} <script type="text/javascript" src="{{ MEDIA_URL }}static/js/my_cool_tweaks.js"> {% endblock extra_head %}
Specific Pages
Since sample_project/templates/codespeed
is the first entry in settings.TEMPLATE_DIRS
you
may override any template on the site simply by creating a new one with the
same name.
- About page: create
sample_project/templates/about.html
:{% extends "codespeed/base_site.html" %} {% block title %}{{ block.super }}: About this project{% endblock %} {% block body %} <div id="sidebar"></div> <div id="about" class="about_content clearfix"> Your content here </div> {% endblock %}
Baselines and Comparison view executables
- The results associated to an executable and a revision which has a non blank tag field will be listed as a baseline option in the Timeline view.
- Additionally, the Comparison view will show the results of the latest revision of projects being tracked as an executable as well.
Defaults
The file sample_project/settings.py
can contain customizations of
several parameters (the file includes comments with full examples).
General settings
WEBSITE_NAME
: The RSS results feed will use this parameter as the site nameDEF_BASELINE
: Defines which baseline option will be chosen as default in the Timeline and Changes views.DEF_ENVIRONMENT
: Defines which environment should be selected as default in the Changes and Timeline views.CHANGE_THRESHOLD
TREND_THRESHOLD
Home Page
The main customization for the homepage is to display either the reports (daily changes) or the historical graphs (improvement over time).
SHOW_REPORTS
: If set toTrue
displays a table and RSS feed with the latest resultsSHOW_HISTORICAL
: Displays two graphs comparing tagged and latest versions of the default executable and project to the configured baseline.
To activate the historical graphs you will need to set the following settings (using values that work with the test data):
DEF_BASELINE = {'executable': 'baseExe', 'revision': '444'}
DEF_EXECUTABLE = "myexe O3 64bits"
Changes View
DEF_EXECUTABLE
: in the Changes view, a random executable is chosen as default. It that doesn't suite you, you can specify here which one should be selected. You need to specify its id (since the name alone is not unique).
Timeline View
DEF_BENCHMARK
: Defines the default timeline view. Possible values:None
: will show a grid of plot thumbnails, or a text message when the number of plots exceeds 30grid
: will always show as default the grid of plotsshow_none
: will show a text message (better default when there are lots of benchmarks)mybench
: will select benchmark named "mybench"
Comparison View
CHART_TYPE
: Chooses the default chart type (normal bars, stacked bars or relative bars)NORMALIZATION
: Defines whether normalization should be enabled as default in the Comparison view.CHART_ORIENTATION
: horizontal or verticalCOMP_EXECUTABLES
: per default all executables will be checked. When there are a large number of tags or executables, it is better to only select a few so that the plots are not too cluttered. Given as a list of tuples containing the name of an executable + commitid of a revision. An 'L' denotes the last revision. Example:
COMP_EXECUTABLES = [
('myexe', '21df2423ra'),
('myexe', 'L'),
]
- `COMPARISON_COMMIT_TAGS: Defines a list of tags to display on the comparison page. This comes
handy when there are a lot of tags. It defaults to
None
which means display all the available tags.
VCS Provider Specific Settings
Github
GITHUB_OAUTH_TOKEN
- Github oAuth token to use for authenticating against the Github API. If not provided, it will default to unauthenticated API requests which have low rate limits so an exception may be thrown when retrieving info from the Github API due to the rate limit being reached.
