Sort the includes accoding to the new coding style.
2015-11-09treewide: apply errno.cocciMichal Schmidt
with small manual cleanups for style.
2015-11-05journal: posix_fallocate() does not set errnoMichal Schmidt
manpage says: posix_fallocate() returns zero on success, or an error number on failure. Note that errno is not set.

2015-10-25util-lib: split out fd-related operations into fd-util.[ch]Lennart Poettering
There are more than enough to deserve their own .c file, hence move them over.
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.
2015-10-24util: split out escaping code into escape.[ch]Lennart Poettering
This really deserves its own file, given how much code this is now.

2015-04-07util: rework cunescape(), improve error handlingLennart Poettering
Change cunescape() to return a normal error code, so that we can distuingish OOM errors from parse errors. This also adds a flags parameter to control whether "relaxed" or normal parsing shall be done. If set no parse failures are generated, and the only reason why cunescape() can fail is OOM.
2015-02-03journald: fix some xsprrintf() buffer size falloutLennart Poettering
2015-02-01Add a snprinf wrapper which checks that the buffer was big enoughZbigniew Jędrzejewski-Szmek
If we scale our buffer to be wide enough for the format string, we should expect that the calculation was correct. char_array_0() invocations are removed, since snprintf nul-terminates the output in any case. A similar wrapper is used for strftime calls, but only in timedatectl.c.
2014-11-28treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt
If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().
2014-11-03journald: constify all things!Lennart Poettering
2014-08-13journald: Fix off-by-one error in "Missed X kernel messages" warningEelco Dolstra
On receiving a message, "kernel_seqnum" is set to "serial + 1". So subtracting 1 will cause messages like "Missed 0 kernel messages", which should be "Missed 1 kernel messages".
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.
2014-07-28journald: always add syslog facility for messages coming from kmsgMichal Sekletar
Set SYSLOG_FACILITY field for kernel log messages too. Setting only SYSLOG_IDENTIFIER="kernel" is not sufficient and tools reading journal maybe confused by missing SYSLOG_FACILITY field for kernel log messages.
2014-05-15Remove unnecessary casts in printfsZbigniew Jędrzejewski-Szmek
No functional change expected :)
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.
2014-02-20api: in constructor function calls, always put the returned object pointer ↵Lennart Poettering
first (or second) Previously the returned object of constructor functions where sometimes returned as last, sometimes as first and sometimes as second parameter. Let's clean this up a bit. Here are the new rules: 1. The object the new object is derived from is put first, if there is any 2. The object we are creating will be returned in the next arguments 3. This is followed by any additional arguments Rationale: For functions that operate on an object we always put that object first. Constructors should probably not be too different in this regard. Also, if the additional parameters might want to use varargs which suggests to put them last. Note that this new scheme only applies to constructor functions, not to all other functions. We do give a lot of freedom for those. Note that this commit only changes the order of the new functions we added, for old ones we accept the wrong order and leave it like that.

2013-11-26tree-wide usage of %m specifier instead of strerror(errno)Daniel Buch
Also for log_error() except where a specific error is specified e.g. errno ? strerror(errno) : "Some user specified message"
2013-06-20journal: allow callers to specify OBJECT_PID=Zbigniew Jędrzejewski-Szmek
When journald encounters a message with OBJECT_PID= set coming from a priviledged process (UID==0), additional fields will be added to the message: OBJECT_UID=, OBJECT_GID=, OBJECT_COMM=, OBJECT_EXE=, OBJECT_CMDLINE=, OBJECT_AUDIT_SESSION=, OBJECT_AUDIT_LOGINUID=, OBJECT_SYSTEMD_CGROUP=, OBJECT_SYSTEMD_SESSION=, OBJECT_SYSTEMD_OWNER_UID=, OBJECT_SYSTEMD_UNIT= or OBJECT_SYSTEMD_USER_UNIT=. This is for other logging daemons, like setroubleshoot, to be able to augment their logs with data about the process. https://bugzilla.redhat.com/show_bug.cgi?id=951627
2013-06-10Use stdint.h macros instead of casts to print uint64_t valuesZbigniew Jędrzejewski-Szmek
Casts are visually heavy, and can obscure unwanted truncations.

2012-11-14build-sys: store journald code in a noinst libraryZbigniew Jędrzejewski-Szmek
The point is to allow the use of journald functions by other binaries. Before, journald code was split into multiple files (journald-*.[ch]), but all those files all required functions from journald.c. And journald.c has its own main(). Now, it is possible to link against those functions, e.g. from test binaries. This constitutes a fix for https://bugzilla.redhat.com/show_bug.cgi?id=872638. The patch does the following: 1. rename journald.h to journald-server.h and move corresponding code to journald-server.c. 2. add journald-server.c and other journald-*.c parts to libsystemd-journal-internal. 3. remove journald-syslog.c from test_journal_syslog_SOURCES, since it is now contained in libsystemd-journal-internal. There are no code changes, apart from the removal of a few static's, to allow function calls between files.
