2016-07-25sd-id128: be more liberal when reading files with 128bit IDsLennart Poettering
Accept both files with and without trailing newlines. Apparently some rkt releases generated them incorrectly, missing the trailing newlines, and we shouldn't break that.
2016-07-22sd-id128: split UUID file read/write code into new id128-util.[ch]Lennart Poettering
We currently have code to read and write files containing UUIDs at various places. Unify this in id128-util.[ch], and move some other stuff there too. The new files are located in src/libsystemd/sd-id128/ (instead of src/shared/), because they are actually the backend of sd_id128_get_machine() and sd_id128_get_boot(). In follow-up patches we can use this reduce the code in nspawn and machine-id-setup by adopted the common implementation.
2016-02-10tree-wide: remove Emacs lines from all filesDaniel Mack
This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
2015-10-27util-lib: split out allocation calls into alloc-util.[ch]Lennart Poettering
2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.
2014-07-31Always prefer our headers to system headersZbigniew Jędrzejewski-Szmek
In practice this shouldn't make much difference, but sometimes our headers might be newer, and we want to test them.
2013-08-22test: Make testing work on systems without or old systemdHolger Hans Peter Freyther
* 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.
2013-04-30id128: when taking user input for a 128bit ID, validate syntaxLennart Poettering
Also, always accept both our simple hexdump syntax and UUID syntax.
