According to its manual page, flags given to mkostemp(3) shouldn't include
O_RDWR, O_CREAT or O_EXCL flags as these are always included. Beyond
those, the only flag that all callers (except a few tests where it
probably doesn't matter) use is O_CLOEXEC, so set that unconditionally.
|

define HEXDIGITS alongside DIGITS, and use it where it's already useful. We'll
use it again shortly when parsing MAC addresses.

This should be handled fine now by .dir-locals.el, so need to carry that
stuff in every file.
|
|
Sort the includes accoding to the new coding style.
|

With this change, the idiom:
r = write_string_file(p, buf, 0);
if (r < 0) {
if (verify_one_line_file(p, buf) > 0)
r = 0;
}
gets reduced to:
r = write_string_file(p, buf, WRITE_STRING_FILE_VERIFY_ON_FAILURE);
i.e. when writing the string fails and the new flag
WRITE_STRING_FILE_VERIFY_ON_FAILURE is specified we'll not return a
failure immediately, but check the contents of the file. If it matches
what we wanted to write we suppress the error and exit cleanly.

There are more than enough to deserve their own .c file, hence move them
over.

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.

All users of get_status_field() expect the field pattern to occur in
the beginning of a line, and the delimiter is ':'.
Hardcode this into the function, and also skip any whitespace before ':'
to support fields in files like /proc/cpuinfo. Add support for returning
the full field value (currently stops on first whitespace).
Rename the function so it's easier to ensure all callers switch to new
semantics.

Merge write_string_file(), write_string_file_no_create() and
write_string_file_atomic() into write_string_file() and provide a flags mask
that allows combinations of atomic writing, newline appending and automatic
file creation. Change all users accordingly.
|
|
Add a flag to control whether write_string_stream() should always enforce a
trailing newline character in the file.

sendfile_full() by it
|
|
Explicitly check the length of the read.
Fixes CID#1250803.
|
|
add tests for the following functions:
- write_string_file_no_create
- load_env_file_pairs
|
|
|
|
The asserts used in the tests should never be allowed to be
optimized away
|
|
t cannot be null here
|
|
|
|
We check the actual contents of the file on the line after but we
might as well also check the number of bytes read here.
Found by coverity. Fixes: CID#1237521
|
|
add tests for:
- write_string_stream
- write_string_file
- sendfile_full
|
|
|
|
Let's unify our code here, and also always specifiy O_CLOEXEC.

test-fileio/test-strv:
Use the streq_ptr to make build-scan not worry about passing in a null
to a nonnull function.
test-dhcp-option:
Prevent a theoretical null pointer dereference
|
|
This is a fairly useless thing to do but it makes the compilers
and analyzers shut up about the use of mktemp.

Travis tests are failing, probably because /proc/meminfo is not available
in the test environment. The same might be true in some virtualized systems,
so just treat missing /proc/meminfo as a sign that hibernation is not
possible.
|
|
Condition that is checked is taken from upower:
active(anon) < free swap * 0.98
This is really stupid, because the kernel knows the situation better,
e.g. there could be two swap files, and then hibernation would be
impossible despite passing this check, or the kernel could start
supporting compressed swap and/or compressed hibernation images, and
then this this check would be too stringent. Nevertheless, until
we have something better, this should at least return a true negative
if there's no swap.
Logging of capabilities in the journal is changed to not strip leading
zeros. I consider this more readable anyway.

bash allows them, and so should we.
string_has_cc is changed to allow tabs, and if they are not wanted,
they must be now checked for explicitly. There are two other callers,
apart from the env file loaders, and one already checked anyway, and
the other is changed to check.

If two instances of test-fileio were run in parallel,
they could fail when trying to write the same file.
This predictable name in /tmp/ wasn't actually a security
issue, because write_env_file would not follow symlinks,
so this could be an issue only when running tests in
parallel.

In case of scripts, _EXE is set to the interpreter name, and
_COMM is set based on the file name. Add a match for _COMM,
and _EXE if the interpreter is not a link (e.g. for yum,
the interpreter is /usr/bin/python, but it is a link to
/usr/bin/python2, which in turn is a link to /usr/bin/python2.7,
at least on Fedora, so we end up with _EXE=/usr/bin/python2.7).
I don't think that such link chasing makes sense, because
the final _EXE name is more likely to change.

systemd does not want to understand comments after the first
non-whitespace char occured.
key=foo #comment will result into key == "foo #comment"
key="foo" #comment will result into key == "foo#comment"
"key= #comment" will result into key == "#comment"
"key #comment" is an invalid line
|
|
Because "export key=val" is not supported by systemd, an error is logged
where the invalid assignment is coming from.
Introduce strv_env_clean_log() to log invalid environment assignments,
where logging is possible and allowed.
parse_env_file_internal() is modified to allow WHITESPACE in keys, to
report the issues later on.
|
|
parse_env_file_internal() could not parse the following lines correctly:
export key="val"
key="val"#comment
|

This will properly escape all weird chars when writing env var files.
With this in place we can now read and write environment files where the
values contain arbitrary weird chars.
This enables hostnamed and suchlike to finally properly save pretty host
names with backlashes or quotes in them.
|
|
Implement this with a proper state machine, so that newlines and
escaped chars can appear in string assignments. This should bring the
parser much closer to shell.
