| 19 | + |
| 20 | +== Update Instructions == |
| 21 | + |
| 22 | +At the end of either method, copy `SAGE_DATA/cremona/cremona.db` to the src directory of the spkg. |
| 23 | + |
| 24 | +=== Method 1 === |
| 25 | + |
| 26 | +If the cremona database has already been installed, remove |
| 27 | +`SAGE_DATA/cremona/cremona.db`. Run |
| 28 | + |
| 29 | +{{{ |
| 30 | +sage: sage.databases.cremona.build('cremona','path/to/ecdata.tgz') |
| 31 | +}}} |
| 32 | + |
| 33 | +=== Method 2 === |
| 34 | + |
| 35 | +Install the current version of the spkg, and copy the new files into a new |
| 36 | +folder. Then run |
| 37 | + |
| 38 | +{{{ |
| 39 | +sage: C = sage.databases.cremona.LargeCremonaDatabase('cremona',False) |
| 40 | +sage: C._init_from_ftpdata('path/to/said/folder',0) |
| 41 | +}}} |
| 42 | + |
| 43 | +This method is much faster, but won't include any potential fixes old entries. |
