1 News (mainly features/major bug fixes)
6 * Add emerge --keep-going option to continue as much as possible after
7 an error. When an error occurs, dependencies are recalculated for
8 remaining packages and any with unsatisfied dependencies are
9 automatically dropped. The --skipfirst option automatically drops
10 packages in the same way, and also drops and masked packages.
11 * Add subversion support for repoman.
12 * It is now possible to use `emerge <file>` to reinstall the package that
13 installed a particular file. Package contents entries are indexed to
14 improve performance. A command such as `emerge /lib/modules` can serve
15 as a decent substitute for module-rebuild.
16 * Namespace sanitizing: move all portage related code into portage.* namespace,
17 rename portage_foo modules to portage.foo (but keep symlinks for compability)
18 * Add license visibility filtering (GLEP 23)
19 * Experimental support for preserving old library files on package upgrades
20 based on FEATURES=preserve-libs
21 * Add support for news items (GLEP 42)
22 * Add support for generic package sets (also see RELEASE-NOTES)
27 * Blockers are now resolved automatically in many more cases
28 than before. When it's safe, blocked packages are uninstalled
29 automatically so that users are no longer inconvenienced with the
30 task. Automatically uninstalled packages are displayed in the merge
31 list, marked "uninstall" and highlighted in red. With the --tree
32 option enabled, it's possible to see which package(s) caused other
33 ones to be automatically uninstalled.
34 * The dependency resolver now has a feedback mechanism that helps make atom
35 selections more consistent with previous selections that have been added to
36 the graph. This solves some common cases of bug #1343.
41 * After the initial setup phase, the original ebuild and eclasses are no
42 longer needed because the same ebuild environment is reused for the
43 entire lifecycle of the package, including uninstallation.
44 * The emerge --search action supports searching of both installed and binary packages
45 The --usepkg and --usepkgonly options control which repositories are searched.
50 * Allow per-module setting of PORTAGE_ELOG_CLASSES
51 * Add new elog module "echo" to simply display messages when emerge exits
52 * Add ** as new token for package.keywords to bypass the keyword visibility layer
53 * USE_EXPAND variables such as LINGUAS support a * wildcard that will enable
54 all of the corresponding flags that are listed in IUSE for a given package.
55 USE_EXPAND wildcards such as linguas_* are supported in USE and package.use.
56 * The merge process preserves the modification timestamp of files that it
57 installs. The unmerge process will not uninstall files that are claimed by
58 another package in the same slot.
59 * PDEPEND is now installed as soon as possible so that it behaves more like
60 RDEPEND. This makes PDEPEND more useful for breaking the dependency cycles
61 that are sometimes triggered by RDEPEND and DEPEND.
62 * Enable "echo" and "save_summary" elog modules by default
63 * Fix -* handling in package.keywords to work as intended (reset the accepted
64 keywords list), also see RELEASE-NOTES.
65 * Make elog functionality available to python code
70 * Ebuilds support default USE flags via +flag in IUSE.
71 * New-style virtuals are now usable for packages that depend on themselves for
73 * Profiles support multiple inheritance and package.use.
74 * CONFIG_PROTECT and CONFIG_PROTECT_MASK both support files (not just
76 * Collision protection handles symlinks properly.
77 * Dependencies can be satisfied by installed packages that do not have matching
78 ebuilds in the portage tree or overlay.
79 * Emerge automatically ignores blockers that are made irrelevant by an upgrade.
80 * Emerge supports "reverse blocker detection" which means that the blockers of
81 installed packages will always be respected.
82 * Emerge builds a complete dependency graph in order to ensure correct merge
83 order and detection of circular dependencies.
84 * The world and system sets allow automatic update of all installed slots.
85 * DEPEND atoms support SLOT dependencies of the form ${CATEGORY}/${PN}:${SLOT}.
86 * Development: Extend PYTHONPATH support to allow overriding the hardcoded
87 /usr/lib/portage/pym for development/testing purposes
88 * New "finalize" hook for elog modules enabling modules to perform actions on
89 shutdown (like dispatching collected messages).
90 * New elog modules mail_summary and save_summary that act like the mail/save
91 modules except that they merge messages from multiple packages in a single
93 * New QA loglevel and matching eqawarn function
94 * `ebuild foo test` now always runs src_test if available
95 * If DOC_SYMLINK_DIR is set portage installs symlinks to html documention there
96 * FEATURES="test" automatically implies USE="test".
101 * Profiles support use.force, package.use.force, and package.use.mask files.
103 portage-2.1 (ongoing via pre releases)
106 * FEATURES="confcache" integration; global caching to speed up configure calls,
107 requires dev-util/confcache
108 * elog framework and accompanying modules for logging ebuild warnings, errors
109 and general notices. Collects eerror/ewarn/elog/einfo messages.
110 * New elog function (should replace einfo in many cases)
111 * version syntax enhancements allowing multiple suffixes and a new 'cvs'
112 version prefix for denoting "live sources" ebuilds.
113 * config files as directories enabling more flexible settings management.
114 * Addition of an register_die_hook method that allows ebuild/eclasses to
115 register functions to be called for better debugging on errors.
116 * Addition of pre and post user hookable functions for each ebuild phase, accessible
117 via portage bashrc. Example would be pre_src_unpack .
118 * cache refactoring- runtime improvement from 35% -> 65%.
119 * Intelligently handle and display USE_EXPAND-based IUSE variables.
120 * FEATURES="parallel-fetch". Download in parallel to compilation.
121 * Include a "changed or new" USE flag output when --verbose isn't specified.
122 * Support for splitting out debug information into separate files in
124 * exec subsystem refactoring (now with less bugs!)
125 * Added sha256 and rmd160 hashes for digests/manifests
126 * Make --emptytree only apply to ${ROOT} rather than always including /.
127 * Allow packages to be upgraded that are only depended on via a
128 "|| ( =cat/pkg-1* =cat/pkg-2* )" construct.
129 * Ebuild output is no longer cut off early when using PORT_LOGDIR.
130 * Distfiles indirection- $DISTFILES access goes through a tmp dir to fail
131 access to files not listed in SRC_URI.
132 * Emerge now uses --resume to restart itself after portage upgrade.
133 * Atomic file updates via the new atomic_ofstream class.
134 * Global updates and fixpackages performance optimizations.
135 * Tests show that file locking is now more reliable.
136 * A bash call stack is printed when an ebuild dies in ebuild.sh.
137 * New rsync option handling by using a generic PORTAGE_RSYNC_EXTRA_OPTS variable
138 * Manifest2 support that will allow digest-* files to be eliminated from the tree.
