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.
2015-11-02core: expose number of file descriptors in fd store on the busLennart Poettering
For each service expose how many file descriptors there are currently in the fd store. (Also, fix the exporting of the fdstore limit, given that the field is just an "unsigned" but we exported it as "uint32_t". Not that there way any effective difference, but let's make this clean...)
2015-11-02proc-cmdline: return proper errors from shall_restore_state()Lennart Poettering
Let's not eat up errors in shall_restore_state(), but in the consumers instead, just for the sake of keeping the library calls generic.

Only that way it actually has an effect on all our sockets, including $NOTIFY_SOCKET.
2015-11-02string-util: rework memory_erase() so that it cannot be optimized awayLennart Poettering
memory_erase() so far just called memset(), which the compiler might optimize away under certain conditions if it feels there's benefit in it. C11 knows a new memset_s() call that is like memset(), but may not be optimized away. Ideally, we'd just use that call, but glibc currently does not support it. Hence, implement our own simplistic version of it. We use a GCC pragma to turn off optimization for this call, and also use the "volatile" keyword on the pointers to ensure that gcc will use the pointers as-is. According to a variety of internet sources, either one does the trick. However, there are also reports that at least the volatile thing isn't fully correct, hence let's add some snake oil and employ both techniques. https://news.ycombinator.com/item?id=4711346

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.

2015-10-31sd-daemon: increase sd_notify() socket buffer sizeLennart Poettering
Let's make sure we don't start blocking on sd_notify() earlier than necessary, let's bump the socket buffer sizes to 8M. We already do something similar for our logging socket buffers, hence apply a similar bump here.

2015-10-31systemctl: add a way to explicitly request client-side unit installingLennart Poettering
This adds support for a new environment variable SYSTEMCTL_INSTALL_CLIENT_SIDE, that ensures that systemctl executes install operations client-side instead of passing them to PID1. This is useful in debugging situations, but even beyond that. However, we don't want to make it official API, hence let's just make it an undocumented environment variable. Similar, add a second variable, SYSTEMCTL_SKIP_SYSV which allows skipping the SysV chkconfig fall-back if set. This is useful for similar reasons, and exposed as undocumented as environment variable for similar reasons, too.

2015-10-30journal-remote: increase memory limit per connection to avoid errors with HTTPSDongsu Park
Explicitly set MHD_OPTION_CONNECTION_MEMORY_LIMIT to a larger value, when setting up microhttpd, to give more memory per HTTP(S) connection. This way systemd-journal-remote can now prevent microhttpd from failing in creating response headers with messages like "Not enough memory for write", especially when lots of HTTPS requests arrive. That's precisely because MHD_OPTION_CONNECTION_MEMORY_LIMIT in libmicrohttpd defaults to 32768, which is in practice insufficient in this case. See also https://gnunet.org/bugs/view.php?id=4007 for more details. Fixes: https://github.com/coreos/bugs/issues/927
