tree-wide: remove Emacs lines from all files This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easy GLIB has recently started to officially support the gcc cleanup attribute in its public API, hence let's do the same for our APIs. With this patch we'll define an xyz_unrefp() call for each public xyz_unref() call, to make it easy to use inside a __attribute__((cleanup())) expression. Then, all code is ported over to make use of this. The new calls are also documented in the man pages, with examples how to use them (well, I only added docs where the _unref() call itself already had docs, and the examples, only cover sd_bus_unrefp() and sd_event_unrefp()). This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we tend to call our destructors these days. Note that this defines no public macro that wraps gcc's attribute and makes it easier to use. While I think it's our duty in the library to make our stuff easy to use, I figure it's not our duty to make gcc's own features easy to use on its own. Most likely, client code which wants to make use of this should define its own: #define _cleanup_(function) __attribute__((cleanup(function))) Or similar, to make the gcc feature easier to use. Making this logic public has the benefit that we can remove three header files whose only purpose was to define these functions internally. See #2008.

util-lib: split out allocation calls into alloc-util.[ch]

util-lib: split string parsing related calls from util.[ch] into parse-util.[ch]

journal: ensure test-journal-stream doesn't get confused by crappy clocks This ensures that we write strictly monotonic timestamps into the journal files, to ensure that we can properly interleave everything correctly. See #175 for details.

util: rework rm_rf() logic - Move to its own file rm-rf.c - Change parameters into a single flags parameter - Remove "honour sticky" logic, it's unused these days

fix gcc warnings about uninitialized variables like: src/shared/install.c: In function ‘unit_file_lookup_state’: src/shared/install.c:1861:16: warning: ‘r’ may be used uninitialized in this function [-Wmaybe-uninitialized] return r < 0 ? r : state; ^ src/shared/install.c:1796:13: note: ‘r’ was declared here int r; ^

tests: use assert_se instead of assert Otherwise they can be optimized away with -DNDEBUG

Always prefer our headers to system headers In practice this shouldn't make much difference, but sometimes our headers might be newer, and we want to test them.

test: Make testing work on systems without or old systemd * Introduce a macro to conditionally execute tests. This avoids skipping the entire test if some parts require systemd * Skip the journal tests when no /etc/machine-id is present * Change test-catalog to load the catalog from the source directory of systemd. * /proc/PID/comm got introduced in v2.6.33 but travis is still using v2.6.32. * Enable make check and make distcheck on the travis build * Use -D"CATALOG_DIR=STR($(abs_top_srcdir)/catalog)" as a STRINGIY would result in the path '/home/ich/source/linux' to be expanded to '/home/ich/source/1' as linux is defined to 1.

tests: add a program for repetitive opening and closing of the journal Basically wraps an example provided by George McCollister. Should help with leaks in the future.

move _cleanup_ attribute in front of the type http://lists.freedesktop.org/archives/systemd-devel/2013-April/010510.html

journal,shared: add _cleanup_journal_close_

journal: add ability to list values a specified field can take in all entries of the journal The new 'unique' API allows listing all unique field values that a field specified by a field name can take in all entries of the journal. This allows answering queries such as "What units logged to the journal?", "What hosts have logged into the journal?", "Which boot IDs have logged into the journal?". Ultimately this allows implementation of tools similar to lastlog based on journal data. Note that listing these field values will not work for journal files created with older journald, as the field values are not indexed in older files.

journal: when browsing the journal via browse.html allow clicking on entries to show their details

journal: implement generic sharable mmap caching logic instead of having one simple per-file cache implement an more comprehensive one that works for multiple files and can actually maintain multiple maps per file and per object type.

journald: initial version of FSPRG hookup This adds forward-secure authentication of journal files. This patch includes key generation as well as tagging of journal files, Verification of journal files will be added in a later patch.

test: allow deletion of temporary files from normal fs Not everybody has /tmp on tmpfs, and this was breaking 'make check'.

journal: size journal data hash table based on maximum file size metrics The default of 2047 hash table entries turned out to result in way too many collisions for bigger files, hence scale the hash table size by the estimated maximum file size.

journal: beef up journal matches considerably we now can take multiple matches, and they will apply as AND if they apply to different fields and OR if they apply to the same fields. Also, terms of this kind can be combined with an overreaching OR.
