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.
build_binary_package installed its ephemeral chroot context into the
process-global manager and read it back with context::current(),
ignoring its ctx parameter: two concurrent builds would re-point each
other's global and each drop would clean up whichever chroot was
current at the time. The guard now keeps the Arc of the context it
created (parented directly on the base context, not on a config-name
lookup), exposes it via context(), and Drop cleans up exactly that
context and restores the exact handle that was current at creation,
so overlapping builds no longer cross-destroy each other.
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'.
std::fs::copy resets the destination mtime to "now", which breaks
timestamp-based build systems (autotools/gnulib). Packages like
'hello' from Debian sid ship pre-generated files alongside their
prerequisites; when the copy flattens all mtimes, make considers the
generated targets out-of-date and tries to regenerate them with tools
(e.g. gperf) that are not declared build-dependencies, failing the
build.
Restore the source modification and access times after every file copy
in pull::copy_dir_all, pull::fetch_archive_sources merge step, and
context::unshare copy_dir_recursive/ensure_available.
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
