2012-07-13  Keith Marshall  <keithmarshall@users.sourceforge.net>

	Disable globbing of command line arguments.

	* src/clistub.c (_CRT_glob): Define and initialise to zero; we don't

	matching name exists.

	method; declare it, providing its implementation in...

	message, until after pre-remove hooks have run; this ensures that any
	output from the pre-remove hook scripts appears in correct sequence.

	* src/pkginst.cpp (pkgInstall): Likewise, for "installing package ..."
	message, in relation to pre-install hooks.

2012-04-26  Keith Marshall  <keithmarshall@users.sourceforge.net>

	Ensure that package removal requests are correctly scheduled.

	* src/pkgdeps.cpp (pkgXmlDocument::Schedule) [ACTION_REMOVE]: Schedule
	as a distinct case, when the installed version is not the most recent
	available release; consideration of this distinct case was previously
	erroneously overlooked.

2012-04-15  Keith Marshall  <keithmarshall@users.sourceforge.net>

	Correct scheduling of new prerequisites when upgrading.

	* src/pkgdeps.cpp (pkgXmlDocument::ResolveDependencies):
	[ACTION_UPGRADE && ACTION_PRIMARY]: Don't exclude scheduling for this
	case of a prerequisite with no previously installed version; it may be
	a delegated primary requirement of a meta-package.

2012-04-15  Keith Marshall  <keithmarshall@users.sourceforge.net>

	Don't require subsystem within user specified version bounds.

	* src/pkgdeps.cpp (pkgActionItem::ApplyBounds): Automatically consider

2012-04-09  Charles Wilson  <mingw@cwilson.fastmail.fm>

	* src/pkgdeps.cpp (pkgActionItem::ApplyBounds): Implement it.

	(get_version_bounds): ...this new static inline function...
	...to acquire any user specified version bounds, check that they can
	be honoured, before scheduling any action; delegate diagnostics to...
	(dmh_notify_no_match): ...this new local helper function, to report
	when they can't, and to indicate viable alternatives.

2012-03-26  Keith Marshall  <keithmarshall@users.sourceforge.net>

	* src/pkgexec.cpp (reinstall_action_scheduled): New inline function.

	* src/climain.cpp: Update copyright notice; add year 2012.

	Don't report failed downloads in respect of virtual packages.

	* src/pkginet.cpp (pkgActionItem::DownloadArchiveFiles): Clear...
	[ACTION_DOWNLOAD]: ...this status flag for any package identified as
	a meta-package; this corrects a further regression introduced with the
	2011-11-09 update, whereby pending download requests for such virtual

	* src/pkgdeps.cpp: Update copyright notice for new year.
	(pkgXmlDocument::Schedule) [!OPTION_PRINT_URIS]: Ensure that...
	[ACTION_DOWNLOAD]: ...this is enabled, when scheduling an install or
	an upgrade action for a package specified as a command line argument;
	this corrects a regression introduced on 2011-11-09, which resulted in

	Fix ill-advised optimisation in $APPROOT environment lookup.

	* src/rites.c (approot_path): Don't save result of getenv() lookup
	across calls; the environment may have been moved in the interim,
	making the original result invalid on any subsequent call.  Also,
	prefer MS-Windows style (with backslashes) for default.
	(pkgLastRites): Report full path name for lastrites.exe, on execl()
	failure, rather than only the path relative to $APPROOT.

2012-02-20  Keith Marshall  <keithmarshall@users.sourceforge.net>

	Propagate sysroot path settings to scripts via the environment.

	to processing of each package install, upgrade, or remove action, so
	as to update environment variable $SYSROOT to represent the sysroot
	path for each package processed, during execution of script hooks.

	Implement hooks to support lua scripting interface.

	* Makefile.in (LIBS): Add -llua.

	* src/pkginst.cpp (pkgInstall): Call InvokeScript as appropriate.
	* src/pkgunst.cpp (pkgRemove): Likewise.

2011-11-09  Keith Marshall  <keithmarshall@users.sourceforge.net>

	Avoid unnecessary downloads for already installed packages.

	* src/pkginet.cpp (pkgActionItem::DownloadSingleArchive): Require
	external scheduling of ACTION_DOWNLOAD; cancel the scheduled request
	on completion, or when not required due to pre-existing local copy.

	prepared to download the associated archive; enable ACTION_DOWNLOAD.

	* src/pkgexec.cpp (pkgActionItem::Schedule) [OPTION_REINSTALL]:
	May need to download the archive, even when the requested package was
	previously installed; schedule ACTION_DOWNLOAD to enable this.

	* src/pkgdeps.cpp (promote): Macro redefined in terms of...
	(with_flags, with_download): ...these new macros; implement and...
	(pkgXmlDocument::ResolveDependencies): ...use them to enable/schedule
	ACTION_DOWNLOAD only when expected that it may be necessary.

2011-11-06  Keith Marshall  <keithmarshall@users.sourceforge.net>

	Fix packaging anomalies for source and licence distributions.

	* Makefile.in (licdist): Link README from ${CURDIR}, not from '..'.
	(srcdist): Explicitly link pkginfo.c from ${CURDIR} to src/pkginfo,
	rather than as implied prerequisite; this avoids a bogus attempt to
	link srcdist-doc into src/pkginfo.

2011-11-06  Keith Marshall  <keithmarshall@users.sourceforge.net>

	Bump version number for subsequent CVS snapshots.

	* configure.ac (AC_INIT): Set version to 0.4-alpha-1.1cvs

	Fix --download-only vs. --reinstall conflict.

	* src/pkgexec.cpp (pkgActionItem::Execute) [OPTION_DOWNLOAD_ONLY]:
	Test for explicit inequality, rather than equality to zero; since the
	2011-08-30 update, which made --download-only also imply --reinstall,
	it will test as non-zero when --reinstall is specified, even though
	--download-only is not.

2011-10-07  Keith Marshall  <keithmarshall@users.sourceforge.net>

	add category selector argument to support source/licence choice.

2011-10-02  Keith Marshall  <keithmarshall@users.sourceforge.net>

	Facilitate downloads using diverse cache directories.

	* src/pkgbase.h (pkgActionItem::DownloadSingleArchive): New private
	method; declare it; it handles the download for a single named archive
	file, and stores it in a specifed cache directory.

	* src/pkginet.cpp (pkgActionItem::DownloadSingleArchive): Implement
	it; factor its code from the original implementation within...

	Work around an autoconf bug (reported by Stefano Sabatini).

	* Makefile.in (VPATH): Use @top_srcdir@ instead of ${srcdir}; current
	autoconf incorrectly elides references to @srcdir@ and ${srcdir} when
	substituting within a VPATH specification for building `in-source'.
	Also, prefer colons to blanks as path name separators, for improved
	portability to non-GNU implementations of make; (recommendation by

	for the containing package.

	the installed package image.

	* src/pkgkeys.h (defaults_key): New key; declare it.
	* src/pkgkeys.c: Some cosmetic formatting (tabulation) adjustments.
	(defaults_key): Implement it; it refers to the `defaults.xml' file.

	* src/climain.cpp (climain): Check `profile_key' for accessibility of
	the `profile.xml' file; if [! R_OK] emit a diagnostic warning, fall

	Add preliminary support for future `-reinstall' option.

	* src/pkgexec.cpp (pkgActionItem::Execute) [ACTION_INSTALL]: Force

	variable; it stores a pointer to a dynamically allocated local copy of
	the invariant `version' argument, to facilitate correct parsing.
	(pkgVersionInfo::build_string): Likewise; it provides similar handling
	for the invariant `build' argument.
	(pkgVersionInfo::Free): New private inline method; it provides a NULL
