2013-04-13Remove a few NULLsZbigniew Jędrzejewski-Szmek
Just {} is used in a lot of places now, and there's nothing special abose those few.

2013-04-11hwclock: use _cleanup_ to simplify functionZbigniew Jędrzejewski-Szmek
2013-04-11errno is positiveZbigniew Jędrzejewski-Szmek
Make sure we compare errno against positive error codes. The ones in hwclock.c and install.c can have an impact, the rest are unlikely to be hit or in code that isn't widely used. Also check that errno > 0, to help gcc know that we are returning a negative error code.
2013-04-11macro: make sure ALIGN() can be calculated constant by the compilerLennart Poettering
If we pass a constant value to ALIGN() gcc should have the chance to calculate the value during compilation rather than runtime, so let's avoid a static inline call if we can.
2013-04-10systemctl: ellipsize job list only when necessary, highlight runningZbigniew Jędrzejewski-Szmek
I was debugging systemd waiting on a missing disk, and noticed that the job listing could use some polishing. Jobs that are actually running are highlighted, so it's easier to see what very actually waiting for. Also, the needed widths are precalculated, to use available columns more ecomically.

2013-04-08util: Avoid memory allocations for formatting pathsHolger Hans Peter Freyther
Avoid memory allocations to construct the path for files in the procfs. The procfs paths are way shorter than the PATH_MAX so we can use snprintf on a string located on the stack. This shows up as a win on x86 using the benchmark program below. $ make libsystemd-shared.la; gcc -O2 -Isrc/systemd/ -Isrc/ \ -o simple-perf-test simple-perf-test.c \ .libs/libsystemd-shared.a -lrt #include "shared/util.h" void test_once(void) { pid_t pid = getpid(); char *tmp = NULL; get_process_comm(pid, &tmp); free(tmp); tmp = NULL; get_process_cmdline(pid, 0, 1, &tmp); free(tmp); is_kernel_thread(pid); tmp = NULL; get_process_exe(pid, &tmp); free(tmp); } int main(int argc, char **argv) { int i; for (i = 0; i < 50000; ++i) test_once(); }

2013-04-05Use _cleanup_ when reading config filesZbigniew Jędrzejewski-Szmek
2013-04-05Add _cleanup_globfree_Zbigniew Jędrzejewski-Szmek
Fixes a memleak in error path in exec_context_load_environment.
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.
2013-04-05PAM, uaccess: check for logind, not for systemdMartin Pitt
It is possible to build systemd without logind or run logind without systemd init. Commit 66e41181 fixed sd_booted() to only succeed for systemd init; with that, testing for systemd init is wrong in the parts that talk to logind. In particular, this affects the PAM module and the "uaccess" udev builtin. Change sd_booted() to a new logind_running() which tests for /run/systemd/seats/.

2013-04-04efivars: un-leak a few stringsZbigniew Jędrzejewski-Szmek
2013-04-04util: tweak format_timespan() a bitLennart Poettering
Make sure to always print out at least one valid component instead of falling back early to 0.
2013-04-04util: add a bit of syntactic sugar to run short code fragments with a ↵Lennart Poettering
different umask
2013-04-04util: make time formatting a bit smarterLennart Poettering
Instead of outputting "5h 55s 50ms 3us" we'll now output "5h 55.050003s". Also, while outputting the accuracy is configurable. Basically we now try use "dot notation" for all time values > 1min. For >= 1s we use 's' as unit, otherwise for >= 1ms we use 'ms' as unit, and finally 'us'. This should give reasonably values in most cases.
2013-04-03time: add suppot for fractional time specificationsLennart Poettering
We can now parse "0.5s" as the same as "500ms". In fact, we can parse "3.45years" correctly, too, and any other unit and fraction length.
2013-04-03fileio: don't check for errors more often than really necessaryLennart Poettering
2013-04-03fileio: write proper env var write-out codeLennart Poettering
This will properly escape all weird chars when writing env var files. With this in place we can now read and write environment files where the values contain arbitrary weird chars. This enables hostnamed and suchlike to finally properly save pretty host names with backlashes or quotes in them.
2013-04-03shared: rework env file readerLennart Poettering
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.
2013-04-03util: rename parse_usec() to parse_sec() sinds the default unit is secondsLennart Poettering
Internally we store all time values in usec_t, however parse_usec() actually was used mostly to parse values in seconds (unless explicit units were specified to define a different unit). Hence, be clear about this and name the function about what we pass into it, not what we get out of it.
2013-04-03util: rename write_one_line_file() to write_string_file()Lennart Poettering
You can write much more than just one line with this call (and we frequently do), so let's correct the naming.

2013-04-01shared/cgroup-show: fix leak of "pid"Zbigniew Jędrzejewski-Szmek
2013-04-01Always use our own MAX/MIN definitionsCristian Rodríguez
code in src/shared/macro.h only defined MAX/MIN in case they were not defined previously. however the MAX/MIN macros implemented in glibc are not of the "safe" kind but defined as: define MIN(a,b) (((a)<(b))?(a):(b)) define MAX(a,b) (((a)>(b))?(a):(b)) Avoid nasty side effects by using our own versions instead. Also fix the warnings derived from this change. [zj: - modify MAX3 macro to fix warning about _a shadowing _a, - do bootchart/svg.c too, - remove unused MIN3.]
2013-03-31Partially revert e62d8c394474Zbigniew Jędrzejewski-Szmek
The ~80 chars per line part wasn't well received.
2013-03-31ModernizationZbigniew Jędrzejewski-Szmek
Use _cleanup_ and wrap lines to ~80 chars and such.
2013-03-31strbuf: replace quick sort with bubble sortZbigniew Jędrzejewski-Szmek
No need to call the heavy artillery, when the original array is sorted. Reduces complexity from n² log n to n log n, where n is the number of items in the array, not very large, but still.
2013-03-31strbuf: fix leak on memory errorZbigniew Jędrzejewski-Szmek
Not very likely, but let's fix it for the matter of principle.
2013-03-31Remove some dead codeZbigniew Jędrzejewski-Szmek
Based on coverity report.
2013-03-31bus: parse matches locally and allow registration of callbacks for themLennart Poettering
This includes code to parse and split up match strings which will also be useful to calculate bloom filter masks when the time comes.
2013-03-30bus: implement server mode, and anonymous authenticationLennart Poettering
2013-03-30prioq: consider a NULL prioq emptyLennart Poettering

2013-03-29utmp: make gcc shut up, we need to pass an int here, not size_tLennart Poettering
2013-03-29Always use errno > 0 to help gccZbigniew Jędrzejewski-Szmek
gcc thinks that errno might be negative, and functions could return something positive on error (-errno). Should not matter in practice, but makes an -O4 build much quieter.
2013-03-28tests: add some silly tests for path-util.cZbigniew Jędrzejewski-Szmek
2013-03-28catalog: open up catalog internalsZbigniew Jędrzejewski-Szmek
In order to write tests for the catalog functions, they are made non-static and start taking a 'database' parameter, which is the name of a file with the preprocessed catalog entries. This makes it possible to make test-catalog part of the normal test suite, since it now only operates on files in /tmp. Some more tests are added.
2013-03-28utmp-wtmp: don't try to read past end of stringZbigniew Jędrzejewski-Szmek
systemd-199/src/shared/utmp-wtmp.c:228: buffer_size_warning: Calling strncpy with a maximum size argument of 32 bytes on destination array "store.ut_line" of size 32 bytes might leave the destination string unterminated. The destination string is unterminated on purpose, but we must remember that.
2013-03-27shared: free dt (temporary dir name) on failVáclav Pavlín
[zj: modified to not to try to rmdir() dir we haven't created.]
2013-03-26tests: skip bus test if bus cannot be openedZbigniew Jędrzejewski-Szmek
To make the result more visible, special return value is used to tell automake that the test was skipped. While at it, use the same return value in other skipped tests.
2013-03-26Simplify the meaning of %sZbigniew Jędrzejewski-Szmek
The rules governing %s where just too complicated. First of all, looking at $SHELL is dangerous. For systemd --system, it usually wouldn't be set. But it could be set if the admin first started a debug shell, let's say /sbin/sash, and then launched systemd from it. This shouldn't influence how daemons are started later on, so is better ignored. Similar reasoning holds for session mode. Some shells set $SHELL, while other set it only when it wasn't set previously (e.g. zsh). This results in fragility that is better avoided by ignoring $SHELL totally. With $SHELL out of the way, simplify things by saying that %s==/bin/sh for root, and the configured shell otherwise. get_shell() is the only caller, so it can be inlined. Fixes one issue seen with 'make check'.
