From 56ac6f984de5e73d7751a870c515c2dc8741d760 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 21 May 2026 09:41:51 +0000 Subject: [PATCH 01/19] feat: lazy git clones via artifactory shim MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For non-root git deps with a fresh artifactory build, probe the package server before cloning. On hit, populate build_dir from the artifactory zip and write a {build_dir}/mama_shim marker that records the URL/branch/tag/ hash/archive so subsequent runs detect the shim and skip the clone. The commit hash is resolved via the existing Git.init_commit_hash() which already supports `git ls-remote` (no working tree needed). When the probe misses we fall back to the original clone path; `did_check_artifactory` is intentionally left unset on shim miss so the post-clone fetch can still pick up a mamafile-declared `target.version`. Shim is read-only after fetch: - `_execute_deploy_tasks` short-circuits with a `mama unshallow` hint - `_execute_run_tasks` refuses `test`/`start` via `_require_source()` - `mama open ` prints the same hint - `papa_deploy_to` refuses any destination containing a mama_shim marker (defense-in-depth for direct callers) - `_should_build` returns False for shims so configure/build never run - `update_mamafile_tag` / `update_cmakelists_tag` short-circuit - `dirty()` removes the marker so the next build re-evaluates Tests cover the marker roundtrip, probe gating (noart / no artifactory / non-git / unresolved hash / fetch miss / fetch hit), the load-time wiring (clone skipped on hit, clone invoked on miss, noart bypass), the guards, and the BuildTarget-level deploy/require-source behavior. 27 new tests, all existing tests still pass. Deferred (will follow up): - shim → real clone transition for `mama unshallow` (currently users can `mama wipe` and rebuild, which works via existing semantics) - explicit `mama update` re-probe path - `target.version` from src_dir/mamafile.py without a clone (sparse-checkout) --- mama/artifactory.py | 54 ++++- mama/build_dependency.py | 110 +++++++++- mama/build_target.py | 27 +++ mama/main.py | 8 +- mama/papa_deploy.py | 11 +- tests/test_artifactory_shim/__init__.py | 0 .../test_shim_buildtarget.py | 115 +++++++++++ .../test_artifactory_shim/test_shim_guards.py | 195 ++++++++++++++++++ .../test_shim_load_integration.py | 179 ++++++++++++++++ .../test_artifactory_shim/test_shim_marker.py | 104 ++++++++++ .../test_artifactory_shim/test_shim_probe.py | 186 +++++++++++++++++ 11 files changed, 981 insertions(+), 8 deletions(-) create mode 100644 tests/test_artifactory_shim/__init__.py create mode 100644 tests/test_artifactory_shim/test_shim_buildtarget.py create mode 100644 tests/test_artifactory_shim/test_shim_guards.py create mode 100644 tests/test_artifactory_shim/test_shim_load_integration.py create mode 100644 tests/test_artifactory_shim/test_shim_marker.py create mode 100644 tests/test_artifactory_shim/test_shim_probe.py diff --git a/mama/artifactory.py b/mama/artifactory.py index f121f43..587bec9 100644 --- a/mama/artifactory.py +++ b/mama/artifactory.py @@ -317,7 +317,7 @@ def artifactory_fetch_and_reconfigure(target:BuildTarget) -> Tuple[bool, list]: archive = artifactory_archive_name(target) if not archive: return (False, None) - + cache_dir = target.dep.dep_dir #target.dep.workspace local_file = normalized_join(cache_dir, f'{archive}.zip') @@ -336,3 +336,55 @@ def artifactory_fetch_and_reconfigure(target:BuildTarget) -> Tuple[bool, list]: return (False, None) console(f' Artifactory unzip {archive}') return unzip_and_load_target(target, local_file) + + +def try_load_artifactory_shim(dep) -> Tuple: + """ + Probe artifactory for a prebuilt package using the commit hash resolved via + `git ls-remote` (no clone).

All subsequent operations check this flag and skip instantly instead of each waiting for their own timeout (previously: N deps × 5s = 50s wasted blocking). Only true network errors trigger the flag. Authentication failures (SSH key rejected, HTTP 401/403) and HTTP 404 are explicitly excluded so that misconfigured credentials don't silently disable all network access.

This skips both the ls-remote probe and the cached-zip re-extraction that _try_artifactory_shim previously did on every invocation. Update mode still bypasses the cached path so a re-extract happens; noart still ls-remotes for staleness.
