NMTST_SWAP() used memcpy() for copying the value, while NM_SWAP() uses
a temporary variable with typeof(). I think the latter is preferable.
Also, the macro is essentially doing the same thing.
We should use the same "is-valid" function everywhere.
Since nm_utils_ipaddr_valid() is part of libnm, it does not qualify.
Use nm_utils_ipaddr_is_valid() instead.
nmtst_main_context_iterate_until*() iterates until the condition is
satisfied. If that doesn't happen within timeout, it fails an assertion.
Rename the function to make that clearer.
The abbreviations "ns" and "ms" seem not very clear to me. Spell them
out to nsec/msec. Also, in parts we already used the longer abbreviations,
so it wasn't consistent.
We no longer add these. If you use Emacs, configure it yourself.
Also, due to our "smart-tab" usage the editor anyway does a subpar
job handling our tabs. However, on the upside every user can choose
whatever tab-width he/she prefers. If "smart-tabs" are used properly
(like we do), every tab-width will work.
No manual changes, just ran commands:
F=($(git grep -l -e '-\*-'))
sed '1 { /\/\* *-\*- *[mM]ode.*\*\/$/d }' -i "${F[@]}"
sed '1,4 { /^\(#\|--\|dnl\) *-\*- [mM]ode/d }' -i "${F[@]}"
Check remaining lines with:
git grep -e '-\*-'
The ultimate purpose of this is to cleanup our files and eventually use
SPDX license identifiers. For that, first get rid of the boilerplate lines.
nmtst_get_rand_int() was originally named that way, because it
calls g_rand_int(). But I think if a function returns an uint32, it
should also be named that way.
Rename.
This removes libnm-glib, libnm-glib-vpn, and libnm-util for good.
The it has been replaced with libnm since NetworkManager 1.0, disabled
by default since 1.12 and no up-to-date distributions ship it for years
now.
Removing the libraries allows us to:
* Remove the horrible hacks that were in place to deal with accidental use
of both the new and old library in a single process.
* Relief the translators of maintenance burden of similar yet different
strings.
* Get rid of known bad code without chances of ever getting fixed
(libnm-glib/nm-object.c and libnm-glib/nm-object-cache.c)
* Generally lower the footprint of the releases and our workspace
If there are some really really legacy users; they can just build
libnm-glib and friends from the NetworkManager-1.16 distribution. The
D-Bus API is stable and old libnm-glib will keep working forever.

Platform had it's own scheme for reporting errors: NMPlatformError.
Before, NMPlatformError indicated success via zero, negative integer
values are numbers from <errno.h>, and positive integer values are
platform specific codes. This changes now according to nm-error:
success is still zero. Negative values indicate a failure, where the
numeric value is either from <errno.h> or one of our error codes.
The meaning of positive values depends on the functions. Most functions
can only report an error reason (negative) and success (zero). For such
functions, positive values should never be returned (but the caller
should anticipate them).
For some functions, positive values could mean additional information
(but still success). That depends.
This is also what systemd does, except that systemd only returns
(negative) integers from <errno.h>, while we merge our own error codes
into the range of <errno.h>.
The advantage is to get rid of one way how to signal errors. The other
advantage is, that these error codes are compatible with all other
nm-errno values. For example, previously negative values indicated error
codes from <errno.h>, but it did not entail error codes from netlink.
We have nm_utils_inet*_ntop(), however:
- that is partly private API libnm-core, and thus only available in
components that have access to that. Partly it's public API of
libnm, but still only available in components that use libnm.
- relying on the static buffers is discouraged for nm_utils_inet*_ntop().
For testing, that is fine as we are in a more controlled envionment.
So, add a test variant that explicitly relies on static buffers.
That way, it's more convenient to use from tests.
- these functions can assert more and are more convenient to use from
tests.
Often, during tests we want to assert against the logged messages.
In fact, most tests enable assertions for all logging and enforce
them with g_test_assert_expected_messages(). So, this is common.
However, sometimes it can be cumbersome to understand which logging
lines will be produced. For example, the next commits will call
nm_dhcp_manager_get() during the tests, which initializes NMDhcpManager
and logs a message which plugin was selected (or an additional warning,
if the selected plugin was not found). The availability of the DHCP plugin
depends on searching the path for "/usr/bin/dhclient", so from testing code
it's hard to determine what will be logged.
Instead, add a way to temporarily disable logging during testing.
"shared/nm-utils" is a loose collection of utility functions.
There is a certain aim that they can be used independently.
However, they also rely on each other.
Add a test that we can build a minimal shared library with
these tools, independent of libnm-core.
keyfile already supports omitting the "connection.id" and
"connection.uuid". In that case, the ID would be taken from the
keyfile's name, and the UUID was generated by md5 hashing the
full filename.
No longer do this during nm_keyfile_read(), instead let all
callers call nm_keyfile_read_ensure_*() to their liking. This is done
for two reasons:
- a minor reason is, that one day we want to expose keyfile API
as public API. That means, we also want to read keyfiles from
stdin, where there is no filename available. The implementation
which parses stdio needs to define their own way of auto-generating
ID and UUID. Note how nm_keyfile_read()'s API no longer takes a
filename as argument, which would be awkward for the stdin case.
- Currently, we only support one keyfile directory, which (configurably)
is "/etc/NetworkManager/system-connections".
In the future, we want to support multiple keyfile dirctories, like
"/var/run/NetworkManager/profiles" or "/usr/lib/NetworkManager/profiles".
Here we want that a file "foo" (which does not specify a UUID) gets the
same UUID regardless of the directory it is in. That seems better, because
then the UUID won't change as you move the file between directories.
Yes, that means, that the same UUID will be provided by multiple
files, but NetworkManager must already cope with that situation anyway.
Unfortunately, the UUID generation scheme hashes the full path. That
means, we must hash the path name of the file "foo" inside the
original "system-connections" directory.
Refactor the code so that it accounds for a difference between the
filename of the keyfile, and the profile_dir used for generating
the UUID.
We commonly don't use the glib typedefs for char/short/int/long,
but their C types directly.
$ git grep '\<g\(char\|short\|int\|long\|float\|double\)\>' | wc -l
587
$ git grep '\<\(char\|short\|int\|long\|float\|double\)\>' | wc -l
21114
One could argue that using the glib typedefs is preferable in
public API (of our glib based libnm library) or where it clearly
is related to glib, like during
g_object_set (obj, PROPERTY, (gint) value, NULL);
However, that argument does not seem strong, because in practice we don't
follow that argument today, and seldomly use the glib typedefs.
Also, the style guide for this would be hard to formalize, because
"using them where clearly related to a glib" is a very loose suggestion.
Also note that glib typedefs will always just be typedefs of the
underlying C types. There is no danger of glib changing the meaning
of these typedefs (because that would be a major API break of glib).
A simple style guide is instead: don't use these typedefs.
No manual actions, I only ran the bash script:
FILES=($(git ls-files '*.[hc]'))
sed -i \
-e 's/\<g\(char\|short\|int\|long\|float\|double\)\>\( [^ ]\)/\1\2/g' \
-e 's/\<g\(char\|short\|int\|long\|float\|double\)\> /\1 /g' \
-e 's/\<g\(char\|short\|int\|long\|float\|double\)\>/\1/g' \

In commit 8a46b25cfa, NetworkManager
bumped its glib dependency to 2.40 or newer.
"nm-glib.h" header is precisely the compatiblity implementation that we
use to cope with older glib versions. Note, that the same implementation
is also used by applet and VPN plugins.
However, applet and VPN plugins don't yet require 2.40 glib. Also,
they don't yet require NetworkManager 1.12.0 API (which was the one
that bumped the glib requirement to 2.40). Hence, when "nm-glib.h"
is used in applet or VPN, it must still cope with older versions,
although, the code is not used by NetworkManager itself.
Partly revert 8a46b25cfa so that nm-glib.h
again works for 2.32 or newer.
The same is true, also for "nm-test-utils.h", which is also used by
applet and VPN plugins.

If the main loop is quit before the timeout expires, we leave the
timeout source running on the main loop context. Since we usually
create the main loop using the default context, the source will fire
on the next main loop we create during the test.
Therefore, destroy the timeout source if it is still active.
