| 26659 | 151 "Save breakpoints when file is saved" |
| 152 # XXX 13 Dec 2002 KBK Currently the file must be saved before it can | |
| 153 # be run. The breaks are saved at that time. If we introduce | |
| 154 # a temporary file save feature the save breaks functionality | |
| 155 # needs to be re-verified, since the breaks at the time the | |
| 156 # temp file is created may differ from the breaks at the last | |
| 157 # permanent save of the file. A break introduced after a save | |
| 158 # will be effective, but not persistent. This is necessary to | |
| 159 # keep the saved breaks synched with the saved file. | |
| 160 # | |
| 161 # Breakpoints are set as tagged ranges in the text. Certain | |
| 162 # kinds of edits cause these ranges to be deleted: Inserting | |
| 163 # or deleting a line just before a breakpoint, and certain | |
| 164 # deletions prior to a breakpoint. These issues need to be | |
| 165 # investigated and understood. It's not clear if they are | |
| 166 # Tk issues or IDLE issues, or whether they can actually | |
| 167 # be fixed. Since a modified file has to be saved before it is | |
| 168 # run, and since self.breakpoints (from which the subprocess | |
| 169 # debugger is loaded) is updated during the save, the visible | |
| 170 # breaks stay synched with the subprocess even if one of these | |
| 171 # unexpected breakpoint deletions occurs. | |
| 172 breaks = self.breakpoints | |
