stage-snaps
Metadata
Current evaluation
Feature request for a stage-snaps keyword (unpack a snap's content into the snap being built, like stage-packages) was implemented and merged in canonical/snapcraft#2468 (commit 0983e4063), then shipped in the 3.2 release; follow-up fixes in #2525 and #3211.
Resolution: closed resolved
Reason: Stage-snaps support was added by merged PR canonical/snapcraft#2468 (commit 0983e4063 "many: support for stage-snaps"), which introduced the stage-snaps grammar/keyword and a Snap source that downloads and unpacks a snap into the stage directory. The feature landed in the 3.2 release changelog, with later refinements in #2525 (catkin plugin ROS dependency check) and #3211 (pluginhandler fix for v2 plugins).

Issue body
It should be possible to dump the content of a snap into the snap being worked on akin to using stage-packages.

| Issue | Project | State | Summary | Similarity |
|---|---|---|---|---|
| #2468 many: support for stage-snaps | snapcraft | merged | Merged in PR #2468 as commit 0983e4063, adding stage-snaps, advanced grammar support, and a snap source for extracting downloaded snaps. | |
| #6095 Allow staging snap components | snapcraft | open | Feature request to support snap components in stage-snaps (snap+component syntax). Triaged as feasible; implementation lives upstream in craft-parts PR #1604, currently on hold pending snapd UX decisions on component access/management. | |
| #1901733 stage-snaps not usable with branches | snapcraft (launchpad) | closed | Stage/build-snap branch channels were identified as blocked by Snapcraft validation, but no fix landed; the item was eventually abandoned and closed as stale. | |
| #1604 feat: handle snap components in stage-snaps | craft-parts | open | Adds snap component support to stage-snaps (unpacking component trees, SNAP_COMPONENTS). Marked draft by mr-cal pending snapd UX decisions; 3 unresolved review threads and 5 CI jobs still failing. | |
| #3211 pluginhandler: fix stage-snaps for v2 plugins | snapcraft | merged | Merged in canonical/snapcraft#3211 (0870f1738), fixing v2 stage-snaps handling and preventing prepare_build from discarding unpacked snaps. | |
| #2127927 Allow {stage,build}-snaps and extensions to point to locally provided snaps | snapcraft (launchpad) | open | Feature request to let build-snaps, stage-snaps, and extension dependencies reference local .snap files; support remains Store-only and the issue has not been triaged. | |
| #270 Support $SNAPCRAFT_STAGE for parts | snapcraft | merged | Merged in canonical/snapcraft#270 via eb033b40c, adding part-time replacement of $SNAPCRAFT_STAGE with the absolute stage-directory path. | |
| #1575 feat(snaps): use '@' for separating stage-snap names from their channels. | craft-parts | merged | Merged PR #1575 by lengau switches stage-snaps/build-snaps name/channel parsing to '@' (snaps.py uses split("@", 1) and rejects padded whitespace), fixing issue #1574; changelog entry added. | |
| #1747778 Snapcraft.yml in 'snap' directory. prime/parts/stage in '.' | snapcraft (launchpad) | open | Feature request (2018) to let snapcraft put parts/stage/prime build dirs next to snap/snapcraft.yaml instead of the project root. Maintainer kyrofa agreed it is desirable; no implementation exists — lifecycle still uses Path.cwd() as work_dir. | |
| #1538688 Support referencing the stage dir from snapcraft.yaml | snapcraft (launchpad) | closed | Implemented SNAPCRAFT_STAGE substitution for part properties and merged the fix in canonical/snapcraft#270 via eb033b40c. |
