Welcome to the Sage Development Organization Page

To get an account, read the trac guidelines, then do either of the following:

  1. Click here to request an account. You need to request to join the Google group sage-trac-account in order for a manager to setup your account.
  2. Email Minh Van Nguyen directly with your full name, your preferred username, and your preferred contact email address.

Make sure you understand the review process, and the procedures for opening and closing tickets. See the Developer's Guide for more information.

BLOCKERS: List of blockers for the next release

Edit this wiki page if you are working on a documentation/doctest ticket.

Sage is free and open software that supports research and teaching in algebra, geometry, number theory, cryptography, etc. Both the Sage development model and the technology in Sage itself are distinguished by an extremely strong emphasis on openness, community, cooperation, and collaboration: we are building the car, not reinventing the wheel.

This web page lists both bugs in Sage and ideas for features to add to Sage. Please help Sage development by posting extensive information about all bugs you know of or find in Sage here, no matter how trivial.

Special Wiki pages for certain topics

This is a list of special places where types of tickets are grouped together for convenience

Formatting hint for bug reports

Please use the {{{ and }}} tags to add code snippets and Sage session transcripts. For example:

{{{
sage: 1 + 2
3
}}}

displays as

sage: 1 + 2
3

You can enable syntax highlighting in these code snippets by using a hashbang (#!) followed by the name of the syntax; for example,

{{{
#!python
def spam ():
    eggs = 3
    return 1
pine_for_fjords()
}}}

displays as

def spam ():
    eggs = 3
    return 1
pine_for_fjords()

This also makes inline diff viewers if you choose the syntax name diff:

{{{
#!diff
# HG changeset patch
# Date 1300721936 0
foo

diff --git a/bar b/bar
--- a/bar
+++ b/bar
@@ -1,2 +1,3 @@
 baz
 quux
+xyzzy
}}}

displays as

  • bar

    # HG changeset patch
    # Date 1300721936 0
    foo
    
    diff --git a/bar b/bar
    a b  
    11baz 
    22quux 
     3xyzzy 

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`. This can also be done for non-code names like MoinMoin (the name of the software behind the sage wiki) by prepending an exclamation mark: !MoinMoin.

Browse Open Issues and Review Some Patches!

Use various reports located at http://trac.sagemath.org/sage_trac/report to browse open tickets. Of particular note, reviewing tickets should be a high priority, because these tickets are typically almost ready to close with little effort. This is accessible from any page in Trac, by the "View Tickets" button.

If you are logged in, one particularly useful report is this one, which gives all open tickets you've somehow participated in.

Here are the public bug reports from the notebook interface.
