2014-09-15hashmap: introduce hash_ops to make struct Hashmap smallerMichal Schmidt
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.
2014-08-18tmpfiles: only execute chmod()/chown() when neededMichael Olbrich
This avoids errors like this, when the paths are already there with the correct permissions and owner: chmod(/var/spool) failed: Read-only file system
2014-08-03Unify parse_argv styleZbigniew Jędrzejewski-Szmek
getopt is usually good at printing out a nice error message when commandline options are invalid. It distinguishes between an unknown option and a known option with a missing arg. It is better to let it do its job and not use opterr=0 unless we actually want to suppress messages. So remove opterr=0 in the few places where it wasn't really useful. When an error in options is encountered, we should not print a lengthy help() and overwhelm the user, when we know precisely what is wrong with the commandline. In addition, since help() prints to stdout, it should not be used except when requested with -h or --help. Also, simplify things here and there.

omitted
2014-06-19tmpfiles: make sure "C" doesn't copy anything if the destination already existsLennart Poettering
Previously it would recursively copy the entire tree in, and descend into subdirectories even if the destination already exists. Let's do what the documentation says and not do that. If files down the tree shall be copied too, they should get their own "C" lines.
2014-06-19tmpfiles: do not fail when copying an empty directoryKay Sievers
2014-06-18tmpfiles: create directories already with the right label, instead of ↵Lennart Poettering
creating them first, and relabeling them afterwards
2014-06-18tmpfiles: w lines should allow following symlinksLennart Poettering
2014-06-18tmpfiles: add "+" modifier support to b, c, p lines in addition to LLennart Poettering
2014-06-16tmpfiles: add new "L+" command as stronger version of "L", that removes the ↵Lennart Poettering
destination before creating a symlink Also, make use of this for mtab as long as mount insists on creating it even if we invoke it with "-n".
2014-06-16tmpfiles: set up selinux label proeprly when creating fifosLennart Poettering

2014-06-12tmpfiles: minor modernizationsLennart Poettering
2014-06-11tmpfiles: add ability to mask access mode by pre-existing access mode on ↵Lennart Poettering
files/directories This way it makes a lot more sense to specify an access mode for "Z" lines.
2014-06-11tmpfiles: remove unnecessary functionLennart Poettering
2014-06-11tmpfiles: when processing lines, always process prefixes before suffixesLennart Poettering
If two lines refer to paths that are suffix and prefix of each other, then always process the prefix first, the suffix second. In all other cases strictly process rules in the order they appear in the files. This makes creating /var/run as symlink to /run a lot more fun, since it is automatically created first.
2014-06-11tmpfiles: static variables populated immediately from the command line ↵Lennart Poettering
should be prefixed with arg_
2014-06-11tmpfiles: always recreate the most basic directory structure in /varLennart Poettering
Let's allow booting up with /var empty. Only create the most basic directories to get to a working directory structure and symlink set in /var.
2014-06-10tmpfiles: get rid of "m" lines, make them redundant by "z"Lennart Poettering
"m" so far has been a non-globbing version of "z". Since this makes it quite redundant, let's get rid of it. Remove "m" from the man pages, beef up "z" docs instead, and make "m" nothing more than a compatibility alias for "z".
2014-06-10tmpfiles: add new "C" line for copying files or directoriesLennart Poettering

2014-06-10label: when clearing selinux context, don't mangle errnoLennart Poettering
2014-04-21implement a union to pad out file_handleDave Reisner
Cases where name_to_handle_at is used allocated the full struct to be MAX_HANDLE_SZ, and assigned this size to handle_bytes. This is wrong since handle_bytes should describe the length of the flexible array member and not the whole struct. Define a union type which includes sufficient padding to allow assignment of MAX_HANDLE_SZ to be correct.
2014-03-18util: replace close_nointr_nofail() by a more useful safe_close()Lennart Poettering
safe_close() automatically becomes a NOP when a negative fd is passed, and returns -1 unconditionally. This makes it easy to write lines like this: fd = safe_close(fd); Which will close an fd if it is open, and reset the fd variable correctly. By making use of this new scheme we can drop a > 200 lines of code that was required to test for non-negative fds or to reset the closed fd variable afterwards.

2014-03-14tmpfiles: add --root option to operate on an alternate fs treeMichael Marineau
This makes it possible to initialize or cleanup an arbitrary filesystem hierarchy in the same way that it would be during system boot.
2014-03-14shared: add root argument to search_and_fopenMichael Marineau
This adds the same root argument to search_and_fopen that conf_files_list already has. Tools that use those two functions as a pair can now be easily modified to load configuration files from an alternate root filesystem tree.

2013-12-30tmpfiles: rename --unsafe to --bootZbigniew Jędrzejewski-Szmek
As suggested by Kay, it is better to describe what is done, not what might happen.
2013-12-24tmpfiles: introduce the concept of unsafe operationsZbigniew Jędrzejewski-Szmek
Various operations done by systemd-tmpfiles may only be safely done at boot (e.g. removal of X lockfiles in /tmp, creation of /run/nologin). Other operations may be done at any point in time (e.g. setting the ownership on /{run,var}/log/journal). This distinction is largely orthogonal to the type of operation. A new switch --unsafe is added, and operations which should only be executed during bootup are marked with an exclamation mark in the configuration files. systemd-tmpfiles.service is modified to use this switch, and guards are added so it is hard to re-start it by mistake. If we install a new version of systemd, we actually want to enforce some changes to tmpfiles configuration immediately. This should now be possible to do safely, so distribution packages can be modified to execute the "safe" subset at package installation time. /run/nologin creation is split out into a separate service, to make it easy to override. https://bugzilla.redhat.com/show_bug.cgi?id=1043212 https://bugzilla.redhat.com/show_bug.cgi?id=1045849

2013-11-06clients: unify how we invoke getopt_long()Lennart Poettering
Among other things this makes sure we always expose a --version command and show it in the help texts.

2013-10-14util: allow trailing semicolons on define_trivial_cleanup_func linesLennart Poettering
Emacs C indenting really gets confused by these lines if they carry no trailing semicolon, hence let's make this nicer for good old emacs. The other macros which define functions already do this too, so let's copy the scheme here. Also, let's use an uppercase name for the macro. So far our rough rule was that macros that are totally not function-like (like this ones, which define a function) are uppercase. (Well, admittedly it is a rough rule only, for example function and variable decorators are all lower-case SINCE THE CONSTANT YELLING IN THE SOURCES WOULD SUCK, and also they at least got underscore prefixes.) Also, the macros that define functions that we already have are all uppercase, so let's do the same here...

2013-04-05Use initalization instead of explicit zeroingZbigniew Jędrzejewski-Szmek
Before, we would initialize many fields twice: first by filling the structure with zeros, and then a second time with the real values. We can let the compiler do the job for us, avoiding one copy. A downside of this patch is that text gets slightly bigger. This is because all zero() calls are effectively inlined: $ size build/.libs/systemd text data bss dec hex filename before 897737 107300 2560 1007597 f5fed build/.libs/systemd after 897873 107300 2560 1007733 f6075 build/.libs/systemd … actually less than 1‰. A few asserts that the parameter is not null had to be removed. I don't think this changes much, because first, it is quite unlikely for the assert to fail, and second, an immediate SEGV is almost as good as an assert.
