This is currently done in gap_reset_workspace(), but I think it's less surprising to find the GAP initialization in the GAP initialization file. Here we add it to sage.gaprc so that it can later be removed from gap_reset_workspace().
This is currently done in gap_reset_workspace(), but I think it's less surprising to find the GAP initialization in the GAP initialization file. Here we add it to sage.g (for the pexpect interface) so that it can later be removed from gap_reset_workspace(). It has already been added to sage.gaprc (for the library interface) in an earlier commit.
Resetting the GAP workspace already initializes a new Gap instance and loads our default collection of packages. There's no need to load anything else in gap_reset_workspace(). The disabling of the color prompt is now handled in both sage.gaprc and sage.g (both GAP interfaces) so we remove that as well. Fixes: sagemathGH-31761

@antonio-rojas does this help your memory usage? |

sagemathgh-37049: Dont load all GAP packages when resetting a workspace The `gap_reset_workspace()` function currently loops through all installed GAP packages (both by sage and on the system) and loads them before saving the new workspace. This is no longer necessary or desired: the two GAP initialization files already load a specific set of packages used in sage, and loading more can cause problems including wasted memory and unexpected changes of behavior. Moreover, the need for _users_ to load additional packages interactively has been documented. Fixes: - sagemath#31761 URL: sagemath#37049 Reported by: Michael Orlitzky Reviewer(s):

sagemathgh-37076: src/sage/tests/gap_packages.py: remove These tests for the installed GAP packages are problematic in a world where Sage can use GAP from the system. Particularly, loading _all_ installed GAP packages is not a safe operation when there might be an enormous number of them. Moreover, with the system GAP, it's not really Sage's reponsibility to ensure that the installed packages load. It _would_ be nice to know that any extra packages from the gap_packages SPKG are installed correctly; however, that type of test would be more appropriate in that SPKG's spkg-check phase.
