30b3d78fac8 (tag: 10.3.beta8) Updated SageMath version to 10.3.beta8

[Emmanuel Charpentier]

On Debian testing running on core i7 + 16 GB RAM, upgrading 10.3.beta8 to 10.3.rc0 initially failed ; deleting and rebuilding the documentation succeeded. Running ptestlong initially raised the seven polybori-related failures already reported. Following Antonio Rojas’ suggestion, I forced the installation of Sage’s brial (by sage -i brial). Then, these tests passed.

Question : how to modify Sage’s configuration (as used by make reconfigure) withit having to re-state all the configuration ?

HTH,

​

eval ./configure $(./config.status --config) --without-system-brial

[Emmanuel Charpentier]

Thanks a lot ! I'll have to ((re-)^n)read the Developer's Guide and the Installation Guide...

Operating System: Fedora Linux 39

Kernel Version: 6.7.3-200.fc39.x86_64 (64-bit)

Processors: 24 × 13th Gen Intel® Core™ i7-13700KF
Memory: 31,2 GiB of RAM

Same persistent error:

Unhandled SIGSEGV: A segmentation fault occurred.

This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.

Goedemiddag Jaap,

would you be so kind to look at logs/tests.log and see where exactly the crash occurs (lines before the crash are printed, so it can be put down to the exact place it).

And post the relevant lines of logs/tests.log here.

Dima

Goedemiddag,

From the logs/tests.log: see attachment.

OS X, Apple Silicon, with many homebrew packages, including a recently upgraded openjpeg (from 2.5.0 to 2.5.1): pillow is failing to build, with the error message

  src/libImaging/Jpeg2KDecode.c:673:43: error: too few arguments to function call, expected 3, have 2
      opj_stream_set_user_data(stream, state);
      ~~~~~~~~~~~~~~~~~~~~~~~~              ^

  │ exit code: 1
  ╰─> See above for output.
 

I'm a little confused about jpeg, though: although this is using openjpeg-2.5.1, Sage's top-level config.log file says

    pkg_cv_libjpeg_CFLAGS=-I/opt/homebrew/Cellar/jpeg-turbo/3.0.1/include
    pkg_cv_libjpeg_LIBS='-L/opt/homebrew/Cellar/jpeg-turbo/3.0.1/lib -ljpeg'

pillow's log file says

    Looking for `libjpeg` using pkg-config.
    Appending path /opt/homebrew/Cellar/jpeg-turbo/3.0.1/lib
    Appending path /opt/homebrew/Cellar/jpeg-turbo/3.0.1/include
    Looking for `libopenjp2` using pkg-config.
    Appending path /opt/homebrew/Cellar/openjpeg/2.5.1/lib
    Appending path /opt/homebrew/Cellar/openjpeg/2.5.1/include/openjpeg-2.5

This is similar to a log file from a successful build, though.  (I don't know how to attach files from the browser interface to Google groups.)

Suggestions?

Compared to the previous version (from January): the differences are

- the new version includes -fno-strict-overflow

- the old version includes -fwrapv

- various version numbers have changed, of course

[Matthias Köppe]

Can confirm also on macOS x86_64 with just upgraded openjpeg. 

And upgrading to pillow-10.2.0 (latest) does NOT help.

I have a workaround for the pillow/openjpeg problem in https://github.com/sagemath/sage/pull/37505
