This update fixes issues that Chris uncovered during testing and addresses comments Mathieu made. Changes since v1: 1. The daemon, in ‘SubstitutionGoal::handleChildOutput’, properly deal with the case where ‘data’ contains several lines, such as a “sha256:…” line and a “success” line. 2. ‘call-with-cached-connection’ catches exceptions that may be raised by (web response) when reusing a stale socket. 3. The connection cache is now an alist instead of a hash table and care is taken to evict old entries once it has reached ‘%max-cached-connections’. 4. Fixed typo in comment in (guix scripts substitute). I’ll go ahead with this version soonish if there are no objections. Ludo’. Ludovic Courtès (6): daemon: 'Agent' constructor takes a list of environment variables. daemon: Use 'Agent' to spawn 'guix substitute --query'. daemon: Factorize substituter agent spawning. daemon: Run 'guix substitute --substitute' as an agent. substitute: Cache and reuse connections while substituting. daemon: Raise an error if substituter doesn't send the expected hash. guix/http-client.scm | 12 +- guix/progress.scm | 8 +- guix/scripts/substitute.scm | 243 ++++++++++++++++++++++++------------ nix/libstore/build.cc | 173 +++++++++++++------------ nix/libstore/local-store.cc | 170 ++++++------------------- nix/libstore/local-store.hh | 25 +--- nix/libutil/util.cc | 6 +- nix/libutil/util.hh | 7 +- tests/substitute.scm | 98 +++++++++------ 9 files changed, 381 insertions(+), 361 deletions(-) -- 2.29.2
