[v2] treewide: treatment of errno and other cleanups
2015-11-09treewide: apply errno.cocciMichal Schmidt
with small manual cleanups for style.
2015-11-06journal: reduce minimum journal file size to 512 KiBMichael Olbrich
For low end embedded systems 4 MiB for each journal file is a lot of memory. Journald will use at least 512 KiB even if JOURNAL_FILE_SIZE_MIN is set to less than that so just use 512 KiB.
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.
2015-11-05treewide: use the negative error codes returned by our functionsMichal Schmidt
Our functions return negative error codes. Do not rely on errno being set after calling our own functions.
2015-11-05journal: fix incorrect errno reportingMichal Schmidt
pread() returns -1 on error and sets errno. Do not use the -1 as errno.
2015-11-05journal: use int64_t instead of long for catalog file sizeMichal Schmidt
This replaces the use of ftell() with ftello() for 64-bit size on all archs. Also drops a pointless check for NULL before calling strbuf_cleanup().
2015-11-05journal: drop unnecessary write_catalog() parameterMichal Schmidt
write_catalog() use the hashmap only to get its size. The size is already given in parameter 'n'.
2015-11-03journal: restore watchdog supportLennart Poettering
2015-11-03journalctl: when we fail to open a journal file, print whyLennart Poettering
When we enumerate journal files and encounter an invalid one, remember which this, and show it to the user. Note the possibly slightly surprising logic here: we store only one path per error code. This means we show all error kinds but not every actual error we encounter. This has the benefit of not requiring us to keep a potentially unbounded list of errors with their sources around, but can still provide a pretty complete overview on the errors we encountered. Fixes #1669.
2015-11-03sd-journal: various clean-ups and modernizationsLennart Poettering
- Always print a debug log message about files and directories we cannot open right when it happens instead of the caller, thus reducing the number of places where we need to generate the debug message. - Always push the errors we encounter immediately into the error set, when we run into them, instead of in the caller. Thus, we never forget to push them in. - Use stack instead of heap memory where we can. - Make remove_file() void, since it cannot fail anyway and always returned 0. - Make local machine check of journal directories explicit in a function, to make things more readable. - Port to all directory listing loops FOREACH_DIRENT_ALL() - sd-daemon is library code, hence never log at higher log levels than LOG_DEBUG.

2015-11-03journal: return better error for empty filesZbigniew Jędrzejewski-Szmek
When reading stuff, we should only return EIO when an actual read error occured, not when we don't like the data for whatever reason. We already return ENODATA for all other kinds of file truncation, hence do the same for the most obvious kind, so that callers know what ENODATA means.

sd-journal.c: port to extract_first_word
2015-11-01journald: never block when sending messages on NOTIFY_SOCKET socketLennart Poettering
Otherwise we might run into deadlocks, when journald blocks on the notify socket on PID 1, and PID 1 blocks on IPC to dbus-daemon and dbus-daemon blocks on logging to journald. Break this cycle by making sure that journald never ever blocks on PID 1. Note that this change disables support for event loop watchdog support, as these messages are sent in blocking style by sd-event. That should not be a big loss though, as people reported frequent problems with the watchdog hitting journald on excessively slow IO. Fixes: #1505.

capability-util.[ch] The files are named too generically, so that they might conflict with the upstream project headers. Hence, let's add a "-util" suffix, to clarify that this are just our utility headers and not any official upstream headers.

We don't need two functions that do essentialy the same, hence drop path_get_parent(), and stick to dirname_malloc(), but move it to path-util.[ch].

journal: fix error handling when compressing journal objects
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.

get_current_dir_name() can return a variety of errors, not just ENOMEM, hence don't blindly turn its errors to ENOMEM, but return correct errors in path_make_absolute_cwd(). This trickles down into a couple of other functions, some of which receive unrelated minor fixes too with this commit.
