squash! build-sys: use #if Y instead of #ifdef Y everywhere
v2:
- fix incorrect setting of HAVE_LIBIDN2
This adds IOVEC_INIT() and IOVEC_MAKE() for initializing iovec structures
from a pointer and a size. On top of these IOVEC_INIT_STRING() and
IOVEC_MAKE_STRING() are added which take a string and automatically
determine the size of the string using strlen().
This patch removes the old IOVEC_SET_STRING() macro, given that
IOVEC_MAKE_STRING() is now useful for similar purposes. Note that the
old IOVEC_SET_STRING() invocations were two characters shorter than the
new ones using IOVEC_MAKE_STRING(), but I think the new syntax is more
readable and more generic as it simply resolves to a C99 literal
structure initialization. Moreover, we can use very similar syntax now
for initializing strings and pointer+size iovec entries. We canalso use
the new macros to initialize function parameters on-the-fly or array
definitions. And given that we shouldn't have so many ways to do the
same stuff, let's just settle on the new macros.
(This also converts some code to use _cleanup_ where dynamically
allocated strings were using IOVEC_SET_STRING() before, to modernize
things a bit)
As a follow-up for db3f45e2d2 let's do the
same for all other cases where we create a FILE* with local scope and
know that no other threads hence can have access to it.
For most cases this shouldn't change much really, but this should speed
dbus introspection and calender time formatting up a bit.
Using conf.set() with a boolean argument does the right thing:
either #ifdef or #undef. This means that conf.set can be used unconditionally.
Previously I used '1' as the placeholder value, and that needs to be changed to
'true' for consistency (under meson 1 cannot be used in boolean context). All
checks need to be adjusted.
The indentation for emacs'es meson-mode is added .dir-locals.
All files are reindented automatically, using the lasest meson-mode from git.
Indentation should now be fairly consistent.
Tests can be run with 'ninja-build test' or using 'mesontest'.
'-Dtests=unsafe' can be used to include the "unsafe" tests in the
test suite, same as with autotools.
v2:
- use more conf.get guards are optional components
- declare deps on generated headers for test-{af,arphrd,cap}-list
v3:
- define environment for tests
Most test don't need this, but to be consistent with autotools-based build, and
to avoid questions which tests need it and which don't, set the same environment
for all tests.
v4:
- rework test generation
Use a list of lists to define each test. This way we can reduce the
boilerplate somewhat, although the test listings are still pretty verbose. We
can also move the definitions of the tests to the subdirs. Unfortunately some
subdirs are included earlier than some of the libraries that test binaries
are linked to. So just dump all definitions of all tests that cannot be
defined earlier into src/test. The `executable` definitions are still at the
top level, so the binaries are compiled into the build root.
v5:
- tag test-dnssec-complex as manual
v6:
- fix HAVE_LIBZ typo
- add missing libgobject/libgio defs
- mark test-qcow2 as manual
It's crucial that we can build systemd using VS2010!
... er, wait, no, that's not the official reason. We need to shed old systems
by requring python 3! Oh, no, it's something else. Maybe we need to throw out
345 years of knowlege accumulated in autotools? Whatever, this new thing is
cool and shiny, let's use it.
This is not complete, I'm throwing it out here for your amusement and critique.
- rules for sd-boot are missing. Those might be quite complicated.
- rules for tests are missing too. Those are probably quite simple and
repetitive, but there's lots of them.
- it's likely that I didn't get all the conditions right, I only tested "full"
compilation where most deps are provided and nothing is disabled.
- busname.target and all .busname units are skipped on purpose.
Otherwise, installation into $DESTDIR has the same list of files and the
autoconf install, except for .la files.
It'd be great if people had a careful look at all the library linking options.
I added stuff until things compiled, and in the end there's much less linking
then in the old system. But it seems that there's still a lot of unnecessary
deps.
meson has a `shared_module` statement, which sounds like something appropriate
for our nss and pam modules. Unfortunately, I couldn't get it to work. For the
nss modules, we need an .so version of '2', but `shared_module` disallows the
version argument. For the pam module, it also didn't work, I forgot the reason.
The handling of .m4 and .in and .m4.in files is rather awkward. It's likely
that this could be simplified. If make support is ever dropped, I think it'd
make sense to switch to a different templating system so that two different
languages and not required, which would make everything simpler yet.
v2:
- use get_pkgconfig_variable
- use sh not bash
- use add_project_arguments
v3:
- drop required:true and fix progs/prog typo
v4:
- use find_library('bz2')
- add TTY_GID definition
- define __SANE_USERSPACE_TYPES__
- use join_paths(prefix, ...) is used on all paths to make them all absolute
v5:
- replace all declare_dependency's with []
- add more conf.get guards around optional components
v6:
- drop -pipe, -Wall which are the default in meson
- use compiler.has_function() and compiler.has_header_symbol instead of the
hand-rolled checks.
- fix duplication in 'liblibsystemd' library name
- use the right .sym file for pam_systemd
- rename 'compiler' to 'cc': shorter, and more idiomatic.
v7:
- use ENABLE_ENVIRONMENT_D not HAVE_ENVIRONMENT_D
- rename prefix to prefixdir, rootprefix to rootprefixdir
("prefix" is too common of a name and too easy to overwrite by mistake)
- wrap more stuff with conf.get('ENABLE...') == 1
- use rootprefix=='/' and rootbindir as install_dir, to fix paths under
split-usr==true.
v8:
- use .split() also for src/coredump. Now everything is consistent ;)
- add rootlibdir option and use it on the libraries that require it
v9:
- indentation
v10:
- fix check for qrencode and libaudit
v11:
- unify handling of executable paths, provide options for all progs
This makes the meson build behave slightly differently than the
autoconf-based one, because we always first try to find the executable in the
filesystem, and fall back to the default. I think different handling of
loadkeys, setfont, and telinit was just a historical accident.
In addition to checking in $PATH, also check /usr/sbin/, /sbin for programs.
In Fedora $PATH includes /usr/sbin, (and /sbin is is a symlink to /usr/sbin),
but in Debian, those directories are not included in the path.
C.f. https://github.com/mesonbuild/meson/issues/1576.
- call all the options 'xxx-path' for clarity.
- sort man/rules/meson.build properly so it's stable
This was exposed by the previous commit. This could be potentially
unpleasant, but we are saved by the fact that this code path was only
taken for journald crashes, where we control COMM and know that it doesn't
contain any special characters. Use log_dispatch which does not do any
format processing to push the message out.
I think it would be a good idea to move such fixed, picked values out of
the main sources into the head of a file, to make sure they are
ultimately tunables.
We check these a number of times, hence let's unify these checks here.
This also allows us to make the PID 1 check more elaborate as we can
check both the PID and the cgroup. Checking the PID has the benefit that
we'll also cover cases where PID 1 might still be in the root cgroup, and
the cgroup check has the benefit that we also cover crashes in forked
off crasher processes (the way we actually do it in systemd)
Given that this is a field primarily processed by computers, and not so
much by humans, assign "1" instead of "yes". Also, use parse_boolean()
as we usually do for parsing it again.
This makes things more alike udev options (as one example), such as
SYSTEMD_READY where we also spit out "1" and "0", and parse with
parse_boolean().

Fixes#1733.
We would only log a terse message when pid1 or systemd-journald crashed.
It seems better to reuse the normal code paths as much as possible,
with the following differences:
- if pid1 crashes, we cannot launch the helper, so we don't analyze the
coredump, just write it to file directly from the helper invoked by the
kernel;
- if journald crashes, we can produce the backtrace, but we don't log full
structured messages.
With comparison to previous code, advantages are:
- we go through most of the steps, so for example vacuuming is performed,
- we gather and log more data. In particular for journald and pid1 crashes we
generate a backtrace, and for pid1 crashes we record the metadata (fdinfo,
maps, etc.),
- coredumpctl shows pid1 crashes.
A disavantage (inefficiency) is that we gather metadata for journald crashes
which is then ignored because _TRANSPORT=kernel does not support structued
messages.
Messages for the systemd-journald "crash" have _TRANSPORT=kernel, and
_TRANSPORT=journal for the pid1 "crash".

We logged about this, but did not attach information directly to the log
entry. It *would* be nice to log the full untruncated size, but afaict, to do
this, we would have to read the full data from the kernel. Doing this just to
log that information seems a bit excessive, in particular when the limit could
be set quite low. So for now let's just add a boolean field.
Most of the fields in the context array come from the kernel (passed
through argv), but two are special: comm and exe. We allocate them
ourselves. We forgot to initialize context[CONTEXT_COMM] with the value
we allocated (introduced in 9aa8202314).
To simplify things, just set context[CONTEXT_COMM] and context[CONTEXT_EXE],
and free those two fields at the end.
Fixes#5442.
Implement --since/--until (-S/-U) in the same fashion as journalctl.
This lets the user filter the results a bit so it would be easier to
find relevant info in case there were many core dumps.
Our coredump handler operates on a "context" supplied by the kernel via
the core_pattern arguments. When we pass off a coredump for processing
to coredumpd we pass along enough information for this context to be
reconstructed. This information is passed in the usual journal fields,
and that means we extended the 1s granularity timestamp to 1µs
granularity by appending 6 zeroes. We need to chop them off again when
reconstructing the original kernel context.
Fixes: #4779
(Note that we only do this for the journal metadata, not for the xattrs,
as the xattrs are only supposed to store the original 1:1 info we
acquired from the kernel.)
This adds a unified "copy_flags" parameter to all copy_xyz() function
calls, replacing the various boolean flags so far used. This should make
many invocations more readable as it is clear what behaviour is
precisely requested. This also prepares ground for adding support for
more modes later on.

Embedding sd_id128_t's in constant strings was rather cumbersome. We had
SD_ID128_CONST_STR which returned a const char[], but it had two problems:
- it wasn't possible to statically concatanate this array with a normal string
- gcc wasn't really able to optimize this, and generated code to perform the
"conversion" at runtime.
Because of this, even our own code in coredumpctl wasn't using
SD_ID128_CONST_STR.
Add a new macro to generate a constant string: SD_ID128_MAKE_STR.
It is not as elegant as SD_ID128_CONST_STR, because it requires a repetition
of the numbers, but in practice it is more convenient to use, and allows gcc
to generate smarter code:

The entry must be a single entry in the journal export format, including the
terminating double newline. The MESSAGE field is now generated on the sender
side.
The advantage is that the reporter can easily pass additional metadata.

One consideration is whether to use the Journal Export Format, or send packets
over a UNIX socket instead. The advantage of current solution is that although
parsing is more complicated on the receiver side, it is much easier to use on the
sender side. I hope this can be used by various languages for which writing
binary structures to a UNIX socket is harder and more likely to be done wrong
than piping of a simple textyish format.
In preparation for subsequenct changes...
Various stack allocations are changed to use the heap. This might be minimally
slower, but probably doesn't matter. The upside is that we will now properly
free all memory that is allocated.
Even if pressing Ctrl-c after spawning gdb with "coredumpctl gdb" is not really
useful, we should let gdb handle the signal entirely otherwise the user can be
suprised to see a different behavior when gdb is started by coredumpctl vs when
it's started directly.
Indeed in the former case, gdb exits due to coredumpctl being killed by the
signal.
So this patch makes coredumpctl ignore SIGINT as long as gdb is running.
For normal arches this doesn't matter, but on arm32 arg_journal_size_max was smaller
than the other *SizeMax variables. This doesn't seem useful.
This is anothet part of the fix in 5206a724a0.
