Add a regression test for the recent breakage of handling improperly
escaped exec strings in unit files.
Code contributed by Martin Pitt:

An Exec*= line with whitespace after modifiers, like
ExecStart=- /bin/true
is considered to have an empty command path. This is as specified, but causes
systemd to crash with
Assertion 'skip < l' failed at ../src/core/load-fragment.c:607, function config_parse_exec(). Aborting.
Aborted (core dumped)
Fix this by logging an error instead and ignoring the invalid line.
Add corresponding test cases. Also add a test case for a completely empty value
which resets the command list.

All other types exported from install.h should be namespaces like this,
hence namespace InstallInfo the same way.
Also, remove external forward definition of UnitFileScope type.

When parsing a unit with a trailing slash after an escaped line break, like
ExecStart=/bin/echo 'foo \
bar'
the split() function (through config_parse()) asserted and crashed pid 1:
Assertion 'current[*l + 1] == quotechars[0]' failed at ../src/shared/util.c:583, function split(). Aborting.
Fix this by returning an error in this case ("trailing garbage").
Add corresponding test case. Also fix the missing "unit" argument of
config_parse_exec() in the comment.

This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.

With a command line like "@/something" we would allocate an array with
0 elements. Avoid that, and add a test too.
|
|
Fixes an error introduced by me when the test was added.

The handling of the command name and other arguments is unified. This
simplifies things and should make them more predictable for users.
Incidentally, this makes ExecStart handling match the .desktop file
specification, apart for the requirment for an absolute path.

Also update TODO, empty environment variables in Environment= and
EnvironmentFile= options work.
|
|
The asserts used in the tests should never be allowed to be
optimized away

It is redundant to store 'hash' and 'compare' function pointers in
struct Hashmap separately. The functions always comprise a pair.
Store a single pointer to struct hash_ops instead.
systemd keeps hundreds of hashmaps, so this saves a little bit of
memory.

Let's unify our code here, and also always specifiy O_CLOEXEC.

Pass on the line on which a section was decleared to the parsers, so they
can distinguish between multiple sections (if they chose to). Currently
no parsers take advantage of this, but a follow-up patch will do that
to distinguish
[Address]
Address=192.168.0.1/24
Label=one
[Address]
Address=192.168.0.2/24
Label=two
from
[Address]
Address=192.168.0.1/24
Label=one
Address=192.168.0.2/24
Label=two

Previously the specifier calls could only indicate OOM by returning
NULL. With this change they will return negative errno-style error codes
like everything else.

* 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.

The information about the unit for which files are being parsed
is passed all the way down. This way messages land in the journal
with proper UNIT=... or USER_UNIT=... attribution.
'systemctl status' and 'journalctl -u' not displaying those messages
has been a source of confusion for users, since the journal entry for
a misspelt setting was often logged quite a bit earlier than the
failure to start a unit.

Implement this with a proper state machine, so that newlines and
escaped chars can appear in string assignments. This should bring the
parser much closer to shell.
|
|
<Lekensteyn> The 198 announcement mentions
"/etc/systemd/systemd/foobar.service.d/*.conf", is that a
typo? I only have a /etc/systemd/system/. Is there a
manpage describing this new feature?

Also split out some fileio functions to fileio.c and provide a SELinux
aware pendant in fileio-label.c

Some commands (like 'find') take a semicolon as separate arg. With
current parser implementation there is no way to pass one.
Patch adds token \;

When looking for symlinks, it doesn't make sense to error-out if
the directory is missing. The user might delete an empty directory.
This check caused test-unit-file to fail when run before installation.
