2014-12-16systemctl: do not use -1 for return codeZbigniew Jędrzejewski-Szmek
Also make the error messages more specific to give a hint to the user how to solve the problem.

No functional change. This is in preparation for using this in systemctl in the future.

2014-12-15unit: handle nicely of certain unit types are not supported on specific systemsLennart Poettering
Containers do not really support .device, .automount or .swap units; Systems compiled without support for swap do not support .swap units; Systems without kdbus do not support .busname units. With this change attempts to start a unsupported unit types will result in an immediate "unsupported" job result, which is a lot more descriptive then before. Also, attempts to start device units in containers will now immediately fail instead of causing jobs to be enqueued that never go away.

2014-12-15shared: time-dst: Avoid buffer overflowMartin Pitt
Commit 681f9718 introduced an additional null terminator for the zone names. Increase the allocation of "transitions" to actually make room for this.

2014-12-13systemctl: handle correctly template units for edit verbRonny Chevalier
Previously, if we provided getty@.service to systemctl edit it would have failed when using the bus because it is an invalid unit name. But it would have succeeded when searching in the filesystem. Now, we check if we have a template, if we do we search in the filesystem, if we don't have a templae and we can use the bus, we do. Furthermore, if we provided getty@tty1.service it would not have worked when searching the filesystem, but it would have worked with the bus. So now, when using the filesystem we use the template name and not the unit name, and the same when logging errors. (Also did a refactoring to avoid a long function)
2014-12-13test-unit-name: add more testsRonny Chevalier
Add more test cases for: - unit_name_is_instance - unit_name_to_instance Add tests for: - unit_name_template - unit_name_is_template
2014-12-13journal: replace contexts hashmap with a plain arrayMichal Schmidt
try_context() is such a hot path that the hashmap lookup is expensive. The number of contexts is small - it is the number of object types. Using a hashmap is overkill. A plain array will do. Before: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 0m9.445s user 0m9.228s sys 0m0.213s After: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 0m5.438s user 0m5.266s sys 0m0.170s
2014-12-13journal: delete unused function mmap_cache_close_contextMichal Schmidt
This never had any callers. Contexts are freed when the MMapCache is freed.
2014-12-13journal: push type_to_context conversion down to journal_file_move_to()Michal Schmidt
2014-12-13journal: have a named enum ObjectTypeMichal Schmidt
2014-12-13journal: consistently use OBJECT_<type> names instead of numbersMichal Schmidt
Note that numbers 0 and -1 are both replaced with OBJECT_UNUSED, because they are treated the same everywhere (e.g. type_to_context() translates them both to 0).
2014-12-13journal: consistently allow type==0 to mean "any type"Michal Schmidt
If type==0 and a non-NULL object were given as arguments to journal_file_hmac_put_object(), its object type check would fail and it would return -EBADMSG. All existing callers use either a positive type or -1. Still, for behavior consistency with journal_file_move_to_object() let's allow type 0 to pass.
2014-12-13journal: move type_to_context() to journal-file.cMichal Schmidt
It has no other callers. It does not need to be in the header file.
2014-12-13journal: remove journal_file_object_keep/release functionsMichal Schmidt
The only user is sd_journal_enumerate_unique() and, as explained in the previous commit (fed67c38e3 "journal: map objects to context set by caller, not by actual object type"), the use of them there is now superfluous. Let's remove them. This reverts major parts of commits: ae97089d49 journal: fix access to munmapped memory in sd_journal_enumerate_unique 06cc69d44c sd-journal: fix sd_journal_enumerate_unique skipping values Tested with an "--enable-debug" build and "journalctl --list-boots". It gives the expected number of results. Additionally, if I then revert the previous commit ("journal: map objects to context set by caller, not to actual object type"), it crashes with SIGSEGV, as expected.
2014-12-13journal: map objects to context set by caller, not by actual object typeMichal Schmidt
When the caller of journal_file_move_to_object() specifies type==0, the object header is at first mapped in context 0. Then after the header is checked, the whole object is mapped in a context determined by the actual object type (which is not even range-checked using type_to_context()). This looks wrong. It should map in the caller-specified context. An old comment in sd_journal_enumerate_unique() supports this view: /* We do not use the type context here, but 0 instead, * so that we can look at this data object at the same * time as one on another file */ Clearly the expectation was that the data object will remain mapped in context 0 without being pushed away by mapping other objects in context OBJECT_DATA. I suspect that this was the real bug that got fixed by ae97089d49 "journal: fix access to munmapped memory in sd_journal_enumerate_unique". In other words, journal_file_object_keep/release are superfluous after applying this patch.
2014-12-13journal: add debug mode for mmap-cache (--enable-debug=mmap-cache)Michal Schmidt
This is useful for exposing unsafe access to mmapped objects after the context that they were mapped in was already moved. For example: journal_file_move_to_object(f1, OBJECT_DATA, p1, &o1); journal_file_move_to_object(f2, OBJECT_DATA, p2, &o2); t = o1->object.type; /* this usually works, but is unsafe */
2014-12-13configure.ac: add a generic --enable-debug, replace --enable-hashmap-debugMichal Schmidt
There will be more debugging options later. --enable-debug will enable them all. --enable-debug=hashmap will enable only hashmap debugging. Also rename the C #define to ENABLE_DEBUG_* pattern.
2014-12-13shared/hashmap.h: fix commentMichal Schmidt
An early version used underscore prefixes for internal functions, but the current version uses the prefix "internal_".

2014-12-12wrap a few *_FOREACH macros in curly bracesThomas Hindoe Paaboel Andersen

2014-12-12nspawn: when booting in ephemeral mode, append random token to machine nameLennart Poettering
Also, when booting up an ephemeral container of / use the system hostname as default machine name. This way specifiyng -M is unnecessary when booting up an ephemeral container, while allowing any number of ephemeral containers to run from the same tree.
2014-12-12nspawn: allow spawning ephemeral nspawn containers based on the root file ↵Lennart Poettering
system of the OS This works now: # systemd-nspawn -xb -D / -M foobar Which boots up an ephemeral container, based on the host's root file system. Or in other words: you can now run the very same host OS you booted your system with also in a container, on top of it, without having it interfere. Great for testing whether the init system you are hacking on still boots without reboot the system!

Make sure we don't call into any bus_kernel_*() functions before b->is_kernel is set to true. Hard-code the CMD_FREE just like the other helpers do.
2014-12-12nspawn: beef up nspawn with some btrfs magicLennart Poettering
This adds --template= to duplicate an OS tree as btrfs snpashot and run it This also adds --ephemeral or -x to create a snapshot of an OS tree and boot that, removing it after exit.
