Moving to Github
There is currently a discussion and vote on sage-devel about moving from Trac to Github. All contributors to Sage and maintainers of Sage user packages are welcome to participate.
Welcome to the SageMath Development Organization Page
SageMath is free and open software that supports research and teaching in algebra, geometry, number theory, cryptography, etc. Both the SageMath development model and the technology in SageMath itself are distinguished by an extremely strong emphasis on openness, community, cooperation, and collaboration: we are building the car, not reinventing the wheel. View our Code of Conduct.
The Sage Trac server (this web page) manages tickets, the equivalents of Issues and Pull Requests (PRs). In addition to bug reports, also ideas for features to add to SageMath are appropriate as tickets.
Getting started
To create tickets, add comments on tickets, and edit wiki pages on this site, you need either a GitHub account or a legacy sage-trac account.
Users with GitHub accounts should use the GitHub Login link. (If you do not have an account on GitHub yet, choose a user name and create a GitHub account.)
Users with legacy sage-trac accounts (account names not starting with "gh-") should use the Login link. Do not to use GitHub login, as it will be treated as a separate user from their original account (unless you actively prefer to switch).
The Help/Guide link in the top right corner provides help with the Trac server.
Reporting a bug
Please help SageMath development by reporting bugs that you encounter, no matter how trivial.
If you need to open a ticket, please use the {{{ and }}} tags to add code snippets and SageMath session transcripts. For example:
| Markup | Displays as |
|---|---|
{{{
sage: 1 + 2
3
}}}
| sage: 1 + 2 3 |
You can also use backticks (`) to demarcate inline code snippets, etc. This is useful around names like DiGraph to avoid an automatic wikilink (DiGraph?), like so: `DiGraph`.
SageMath makes use of many upstream projects, which have their own bug tracking pages. A selection: Cython, fflas-ffpack, GAP, GCC (instructions), Givaro, JMol, LinBox, Maxima, Numpy, PARI/GP (instructions), Python, Singular.
Following the pulse of development
Follow the Trac development timeline or active tickets by time, or view other ticket reports.
Help by reviewing Tickets needing review (see checklist).
Catch up on Open tickets you've participated in or make a Custom query.
Contribute to the Release notes for the current development series by collaborative editing.
Explore the Open meta-tickets on larger tasks or topical pages on Algebra, Coding Theory, Combinatorics, Manifolds, Optimization, Polyhedral Geometry, Symbolics.
Discuss in sage-devel or one of our other development groups.
Contributing by working on tickets
Our FAQ on contributing to SageMath will take you to sections Working on tickets and Working with git in the Developer's Guide. Make sure you understand the review process, and the procedures for opening and closing tickets.
When opening a ticket to make a feature request or to plan a project, you may find our Feature request guidelines helpful.
After pushing a branch to a ticket, the ticket will show badges linking to results of automated tests that run on the patchbot and other tests that run on GitHub Actions.
Surveying the mathematical software landscape
The SageMath project is a major integrating force in the math software landscape. Follow the ticket numbers to see how you can help; for example, by surveying software, building or extending interfaces, or contributing to distribution packaging.
This table is being moved to the Sage developer's guide in #34526; do not edit.
Maintaining the social and technical infrastructure
Participate in or help organize Workshops and other activities, or contribute to the Sage community by answering questions.
You can also help maintain the Technical project infrastructure.
Additional formatting hints
You can enable syntax highlighting in these code snippets by using a hashbang (#!) followed by the name of the syntax. This also makes inline diff viewers if you choose the syntax name diff.
| Markup | Displays as | ||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
{{{
#!python
def spam ():
eggs = 3
return 1
pine_for_fjords()
}}}
| def spam (): eggs = 3 return 1 pine_for_fjords() |
||||||||||||
{{{
#!diff
foo
diff --git a/bar b/bar
--- a/bar
+++ b/bar
@@ -1,2 +1,3 @@
baz

+xyzzy
}}}
|
|
To avoid an automatic wikilink for non-code names like GitHub, prepend it with an exclamation mark: !GitHub. See WikiFormatting for more information.
Account Names Mapped to Real Names (to be moved to Sage developer map)
Below is a list of over 600 account holders in Sage's Trac. If your information appears here, please add your information to the SageMath developer world map by editing the file contributors.xml and then remove it here. At the beginning of Oct 2022, we will bulk-merge the remaining info into contributors.xml. By removing your already-merged data here, you'll save us the time to check which of the information (in contributors.xml or here) is more current.
