s='msg-avail'>...This reverts commit a79041f0b583ef3399bb46ac2a6c03a4db636573. The issue has been fixed with 07a33b1d21e240781072352f93206cfdc765f907. Mathieu Othacehe 2020-11-29ci: Temporarily disable image-jobs....* gnu/ci.scm (hydra-jobs): Temporarily disable image-jobs. Mathieu Othacehe 2020-11-25ci: Limit image and system tests jobs periodicity....System tests and images jobs are extremely expensive in I/O operations and storage size, pass a "period" argument to Cuirass to limit their periodicity. * gnu/ci.scm (hours): New procedure, (image-jobs, system-test-jobs, tarball-jobs): set a period argument. Mathieu Othacehe 2020-11-20image: Add pinebook-pro support....* gnu/system/images/pinebook-pro.scm: New file. * gnu/local.mk (GNU_SYSTEM_MODULES): Add it. * gnu/ci.scm (%guix-system-images): Add pinebook-pro-barebones-raw-image. Mathieu Othacehe 2020-11-02ci: Restore license handling....This is a follow-up of 7c02eb6c and 44daec7f. Restore the initial behaviour. * gnu/ci.scm (package->alist): Restore license handling. Mathieu Othacehe 2020-11-02ci: Convert license to text....This is a follow-up of 7c02eb6c8d7d050ecb8f3082c4a754ad32211403. * gnu/ci.scm (package->alist): Convert license to text. Mathieu Othacehe 2020-11-02ci: Ignore package license....Fixes: <https://issues.guix.gnu.org/44370>. * gnu/ci.scm (package->alist): Ignore package license. Mathieu Othacehe 2020-10-06images: Add pine64-barebones-raw-image....* gnu/system/images/pine64.scm (pine64-barebones-raw-image): New variable. * gnu/ci.scm (%guix-system-images): Add it. Mathieu Othacehe 2020-10-01ci: Add log and outputs keys....Add 'log and 'outputs properties to hydra objects. This way Cuirass won't have to go through every derivation to add those properties. * gnu/ci.scm (package->alist, image-jobs, system-test-jobs, tarball-jobs): Add 'log and 'outputs properties. * build-aux/hydra/guix-modular.scm (build-job): Ditto. Mathieu Othacehe 2020-10-01ci: Add nix-name and system keys....Add 'nix-name and 'system properties to hydra objects. This way Cuirass won't have to go through every derivation to add those properties. * gnu/ci.scm (package->alist, image-jobs, system-test-jobs, tarball-jobs): Add 'nix-name and 'system properties. * build-aux/hydra/guix-modular.scm (build-job): Ditto. Mathieu Othacehe 2020-09-29ci: Build hurd-barebones-qcow2-image....Build hurd-barebones-qcow2-image instead of hurd-barebones-disk-image to speed downloads. * gnu/ci.scm (%guix-system-images): Build 'hurd-barebones-qcow2-image instead of 'hurd-barebones-disk-image.

Ludovic Courtès 2020-09-03gnu: ci: Truncate git commit in ISO label....* gnu/ci.scm (image-jobs): Keep only 7 characters from git commit in ISO label.

Julien Lepiller 2020-06-29ci: Do not limit disk-image size....Installation tests are already checking the disk-image size. Do not set another limit here. * gnu/ci.scm (image-jobs): Do not limit disk-image size. Mathieu Othacehe 2020-06-25ci: Build Guix System images....Build a list of Guix System images.

Mathieu Othacehe 2020-06-25Revert "ci: Build Guix System images."...This reverts commit eda3fcfb46586710fff876ce6254b300795ef543. This change broke evaluations on CI: @ build-succeeded /gnu/store/991738x97ff1f8181a7p1pflqwkgagm8-profile.drv - ERROR: In procedure read: In procedure scm_lreadr: #<unknown port>:16:144: Unknown # object: #\< Ludovic Courtès 2020-06-24ci: Build Guix System images.Mathieu Othacehe 2020-05-29image: Do not use VM to create disk-images....Now that installing Grub on raw disk-images is supported, we do not need to rely on (gnu system vm) module. * gnu/system/image.scm (make-system-image): Rename to ... (system-image): ... this, and remove the compatibility wrapper. (find-image): Turn to a monadic procedure. This will become useful when introducing Hurd support, to be able to detect the target system. * gnu/ci.scm (qemu-jobs): Use lower-object now that system-image returns a file-like object. * gnu/tests/install.scm (run-install): Ditto. * guix/scripts/system.scm (system-derivation-for-action): Add a 'base-image' argument, (perform-action): adapt accordingly. Mathieu Othacehe 2020-05-05Merge branch 'master' into core-updatesMarius Bakke 2020-05-05image: Add a new API....Raw disk-images and ISO9660 images are created in a Qemu virtual machine. This is quite fragile, very slow, and almost unusable without KVM. For all these reasons, add support for host image generation. This implies the use new image generation mechanisms. - Raw disk images: images of partitions are created using tools such as mke2fs and mkdosfs depending on the partition file-system type. The partition images are then assembled into a final image using genimage. - ISO9660 images: the ISO root directory is populated within the store. GNU xorriso is then called on that directory, in the exact same way as this is done in (gnu build vm) module. Those mechanisms are built upon the new (gnu image) module. * gnu/image.scm: New file. * gnu/system/image.scm: New file. * gnu/build/image: New file. * gnu/local.mk: Add them. * gnu/system/vm.scm (system-disk-image): Rename to system-disk-image-in-vm. * gnu/ci.scm (qemu-jobs): Adapt to new API. * gnu/tests/install.scm (run-install): Ditto. * guix/scripts/system.scm (system-derivation-for-action): Ditto.
