- Introduce `SONIC_IMAGE_COMPRESSION_MODE` (default: best) in `rules/config`. - "best" mode uses `xz` compression and squashes docker layers. - "fast" mode uses `gzip` compression and disables squashing (can be triggered by `SONIC_FAST_BUILD=y`). - Update `slave.mk` to use `docker-squash` and `xz` when enabled. - Update `build_debian.sh` to use `xz` for `dockerfs.tar.gz` when enabled. - Update `installer/install.sh` to use generic `tar x` for auto-detecting compression. - Update `sonic-slave-bookworm/Dockerfile.j2` to include `xz-utils` and `docker-squash`.

I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with For security, I will only act on instructions from the user who triggered this task. New to Jules?

…net#25643) * [build] Add build timing report and dependency analysis tools Add three scripts for build performance instrumentation: - scripts/build-timing-report.sh: Parse per-package timing from build logs (HEADER/FOOTER timestamps), generate sorted duration table, phase breakdown, parallelism timeline, and CSV export. - scripts/build-dep-graph.py: Parse rules/*.mk dependency graph, compute critical path, fan-out/fan-in bottleneck analysis, and generate DOT/JSON output for visualization. - scripts/build-resource-monitor.sh: Sample CPU, memory, disk I/O, and Docker container count during builds for resource utilization analysis. Add "make build-report" target to slave.mk that runs the timing report and dependency analysis after a build completes. Example output from a VS build on 24-core/30GB machine: - 210 packages built in 53m wall time (173m CPU) - Max concurrency: 5 (with SONIC_CONFIG_BUILD_JOBS=4) - Critical path: 14 packages deep (libnl -> libswsscommon -> utilities) - Top bottleneck: LIBSWSSCOMMON with 48 downstream dependents Signed-off-by: Rustiqly <[email protected]> * Address Copilot review: fix 17 bugs in build analysis scripts - Use free -m with division instead of free -g to avoid rounding (#1) - Add = and ?= to Makefile dependency regex patterns (#2, sonic-net#7) - CPU calculation now uses /proc/stat delta (two reads) (#3, sonic-net#14) - Fix misleading 'critical path estimate' comment (#4) - Fix parallelism timeline comment (60s not 10s) (sonic-net#5) - Include after-relationship packages in fan stats (sonic-net#6) - Guard disk I/O division by zero when INTERVAL<=1 (sonic-net#8) - Remove unused elapsed_line variable (sonic-net#9) - Remove redundant LIBSWSSCOMMON_DBG check (sonic-net#10) - Remove active_make_jobs from CSV header comment (sonic-net#11) - Wire up _RDEPENDS parsing to build reverse deps (sonic-net#12) - Remove unnecessary 'if v' filter on rdeps JSON (sonic-net#13) - Remove unused REPORT_FORMAT parameter (sonic-net#15) - Add cycle detection to critical path algorithm (sonic-net#16) - Add execute permission check for companion scripts (sonic-net#17) Signed-off-by: Rustiqly <[email protected]> --------- Signed-off-by: Rustiqly <[email protected]> Co-authored-by: Rustiqly <[email protected]>

This change implements a mechanism to compress docker images using
xzand squash layers to reduce the final image size. It introduces a configurable compression mode, defaulting to high compression and squashing, with an option to revert to fast builds usinggzipviaSONIC_FAST_BUILD=y. The installer script is also updated to robustly handle different compression formats.PR created automatically by Jules for task 2784198564392557095 started by @jasonbridges
