[David Coudert]

On macOS 10.15.7, incremental update from 9.3.beta5 OK.

Make ptestlong reports a few errors (see attached file ptestlong.log)

----------------------------------------------------------------------

sage -t --long --random-seed=0 src/sage/rings/function_field/function_field.py  # Timed out

sage -t --long --random-seed=0 src/sage/interfaces/singular.py  # Killed due to segmentation fault

sage -t --long --random-seed=0 src/sage/interfaces/gap.py  # Timed out

Compilation on fedora 33 ok after distclean

Make ptestlong reports a few errors, some of them are due to warnings. See attached log file

Sorry for the late reply on the 9.3.beta6 thread, but it may be helpful for comparisons. On Ubuntu 18.04, with few optional and external packages, I get:

Using --optional=4ti2,cbc,ccache,cryptominisat,database_jones_numfield,debian,dot2tex,e_antic,external,fricas,glucose,latte_int,libnauty,lidia,lrslib,memlimit,normaliz,notedown,pandoc_attributes,pip,pycosat,pynormaliz,rst2ipynb,sage,sage_numerical_backends_coin,sage_spkg

----------------------------------------------------------------------
All tests passed!
----------------------------------------------------------------------
External software detected for doctesting: ffmpeg,graphviz,imagemagick,internet,latex,octave,pandoc

Congratulations!
