* Revision 1.3 2004/05/17 15:47:57 bh |
| 41 |
* Update to newest shapelib and get rid of Thuban specific extensions, |
| 42 |
* i.e. use the new DBFUpdateHeader instead of our DBFCommit kludge |
| 43 |
* |
| 44 |
* * libraries/shapelib/shpopen.c: Update to version from current |
| 45 |
* shapelib CVS. |
| 46 |
* |
| 47 |
* * libraries/shapelib/shapefil.h: Update to version from current |
| 48 |
* shapelib CVS. |
| 49 |
* |
| 50 |
* * libraries/shapelib/dbfopen.c: Update to version from current |
| 51 |
* shapelib CVS. |
| 52 |
* (DBFCommit): Effectively removed since shapelib itself has |
| 53 |
* DBFUpdateHeader now which is better for what DBFCommit wanted to |
| 54 |
* achieve. |
| 55 |
* We're now using an unmodified version of dbfopen. |
| 56 |
* |
| 57 |
* * libraries/pyshapelib/dbflib_wrap.c, libraries/pyshapelib/dbflib.py: |
| 58 |
* Update from dbflib.i |
| 59 |
* |
| 60 |
* * libraries/pyshapelib/dbflib.i (DBFInfo_commit): New. Implementation of |
| 61 |
* the commit method. This new indirection is necessary because we use the |
| 62 |
* DBFUpdateHeader function now which is not available in shapelib <= |
| 63 |
* 1.2.10 |
| 64 |
* (DBFFile::commit): Use DBFInfo_commit as implementation |
| 65 |
* (pragma __class__): New. Kludge to remove the commit method when |
| 66 |
* the DBFUpdateHeader function isn't available |
| 67 |
* (_have_commit): New. Helper for the pragma kludge. |
| 68 |
* |
| 69 |
* * libraries/pyshapelib/setup.py (dbf_macros): New. Return the |
| 70 |
* preprocessor macros needed to compile the dbflib wrapper. Determine |
| 71 |
* whether DBFUpdateHeader is available and define the right value of |
| 72 |
* HAVE_UPDATE_HEADER |
| 73 |
* (extensions): Use dbf_macros for the dbflibc extension |
| 74 |
* |
| 75 |
* * setup.py (extensions): Add the HAVE_UPDATE_HEADER macro with |
| 76 |
* value '1' to the Lib.dbflibc extension. This simply reflects the |
| 77 |
* shapelib and pyshapelib updates |
| 78 |
* |
