cargo test used to be unreadable: subprocesses inherited the terminal, so
dpkg-buildpackage, apt and configure output interleaved with the harness
summary, and env_logger lines from parallel tests crossed each other.
New test_support module, compiled into test binaries only (inert stubs
otherwise) and initialized before main via .init_array:
- all log output goes to target/pkh-test-logs/<test>.log, one file per
test thread, so concurrent tests never interleave
- context-launched commands are captured line by line into the same file
(driver-level wrapper); test-code spawns use run_logged()
- a panic hook records failures and an atexit callback prints a matrix
(test name, panic location, message, log path) after the libtest
summary; tests panicking on purpose can opt out with a guard
Also fixes two test bugs found on the way:
- diff_checkbuilddeps_matrix compared dpkg-checkbuilddeps diagnostics
against English messages without pinning the locale
- run_source_build in differential tests now captures output like the
live-UI path does
set_current held the config RwLock for writing across make_context,
which for a context with a parent re-entered the same lock through
Context::new's global-manager lookup, deadlocking 'pkh context use'.
Context building is now lock-free by construction: make_context
resolves parent chains against a snapshot map (also rejecting parent
cycles), and neither set_current nor remove_context holds a guard
while building a Context.
A corrupt contexts.json no longer aborts every command at manager
init: load falls back to the default local-only config, backs the
corrupt file up to contexts.json.bak so a later save cannot silently
destroy it, and a dangling current/parent context falls back to local
with an error log instead of panicking.
All three non-local drivers assembled remote/chroot command strings by
raw concatenation: ssh pushed args verbatim (TODO: escape), schroot
interpolated env values raw so DEB_BUILD_OPTIONS='parallel=4 nocheck'
made sh treat 'nocheck' as the command, and unshare wrapped args in
unescaped double quotes letting quotes break out and $/backticks
expand. Add a shared POSIX shell_quote helper and use it for every
component interpolated into a shell string, including ssh copy_path
(which used Rust's {:?}, not shell quoting) and schroot write_file
(which also switches echo -ne to printf %s so backslash sequences in
content are no longer interpreted).
Copying a git checkout verbatim into /tmp/pkh-build-*/ ships '.git',
flipping autotools' building-from-VCS detection (GNU hello's
BUILD_FROM_GIT): the shipped man page gets cleaned and regenerated
via help2man, which is correctly not in Build-Depends. Skip VCS
dirs (.git/.hg/.svn/.bzr/CVS) in local/unshare/ssh copies, and
prune them after an unshare overlayfs mount.
Route 'pkh build' through the DebUi capture machinery 'pkh deb'
already uses instead of letting dpkg-source inherit the terminal:
- pin LANG=C and LC_ALL=C so dpkg-source emits deterministic English
diagnostics regardless of the session locale;
- new DpkgSourceClassifier rewrites info:/warning:/error: lines into
colored pane entries, telling benign tar warnings from failures;
- DebUi generalizes for reuse (arbitrary phase labels, build-specific
log naming); run_source_build() drives phases and pipes subprocess
output through the sink when a UI is present;
- glyph-free house-style summaries: 'Built in Ns:' plus artifact
paths relative to cwd; failures print captured errors + log path;
- drop/capitalize pipeline chatter, add 'pkh build --verbose' to
bypass the view like 'pkh deb --verbose'.
Multiple changes:
- New contexts (schroot, unshare)
- Cross-building quirks, with ephemeral contexts and repositories management
- Contexts with parents, global context manager, better lifetime handling
- Local building of binary packages
- Pull: pulling dsc files by default
- Many small bugfixes and changes
