Let's underline the header line of the table shown by cgtop, how it is
customary for tables. In order to do this, let's introduce new ANSI
underline macros, and clean up the existing ones as side effect.

Also, when the child is potentially long-running make sure to set a
death signal.
Also, ignore the result of the reset operations explicitly by casting
them to (void).

This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.

systemd-delta man page promises that multiple types of deltas will be
concatenated if they are listed with a comma as separator. Replace
FOREACH_WORD() with FOREACH_WORD_SEPARATOR() to restore the functionality.

Using the same scripts as in f647962d64e "treewide: yet more log_*_errno
+ return simplifications".
|
|
If the format string contains %m, clearly errno must have a meaningful
value, so we might as well use log_*_errno to have ERRNO= logged.
Using:
find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/'
Plus some whitespace, linewrap, and indent adjustments.
|
|
|
|
It corrrectly handles both positive and negative errno values.
|
|
As a followup to 086891e5c1 "log: add an "error" parameter to all
low-level logging calls and intrdouce log_error_errno() as log calls
that take error numbers", use sed to convert the simple cases to use
the new macros:
find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/'
Multi-line log_*() invocations are not covered.
And we also should add log_unit_*_errno().

Found by Coverity. Fixes CID #1237541.

It is redundant to store 'hash' and 'compare' function pointers in
struct Hashmap separately. The functions always comprise a pair.
Store a single pointer to struct hash_ops instead.
systemd keeps hundreds of hashmaps, so this saves a little bit of
memory.

getopt is usually good at printing out a nice error message when
commandline options are invalid. It distinguishes between an unknown
option and a known option with a missing arg. It is better to let it
do its job and not use opterr=0 unless we actually want to suppress
messages. So remove opterr=0 in the few places where it wasn't really
useful.
When an error in options is encountered, we should not print a lengthy
help() and overwhelm the user, when we know precisely what is wrong
with the commandline. In addition, since help() prints to stdout, it
should not be used except when requested with -h or --help.
Also, simplify things here and there.

String which ended in an unfinished quote were accepted, potentially
with bad memory accesses.
Reject anything which ends in a unfished quote, or contains
non-whitespace characters right after the closing quote.
_FOREACH_WORD now returns the invalid character in *state. But this return
value is not checked anywhere yet.
Also, make 'word' and 'state' variables const pointers, and rename 'w'
to 'word' in various places. Things are easier to read if the same name
is used consistently.
mbiebl_> am I correct that something like this doesn't work
mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-passwd "Unlock EncFS"'
mbiebl_> systemd seems to strip of the quotes
mbiebl_> systemctl status shows
mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-password Unlock EncFS $RootDir $MountPoint
mbiebl_> which is pretty weird

Let's unify generation of unicode chars at one place.
Also, don't add an extra space into chars we print, except for the tree
chars where this is really necessary.

systemd-delta /run/systemd/system will show all unit overrides
in /run, etc.
|
|
Also, fix highlighting, add more debug statements, make const tables
static and global, run path_kill_slashes only at entry.
|

The only problem is that libgen.h #defines basename to point to it's
own broken implementation instead of the GNU one. This can be fixed
by #undefining basename.
|
|
Among other things this makes sure we always expose a --version command
and show it in the help texts.
|
|
This make systemd-delta follow the behaviour of systemctl
and journalctl.

$ journalctl -be

Yay, we now have a completely generic systemd. No distribution specific checks anymore!
|

Both the help and man page claims that it accepts -t with an argument
so let's do that.

Make sure to allocate enough space for readdir_r().

This is to match strappend() and the other string related functions.

Thankfully nobody is using this yet, and presets aren't documented yet,
hence take the liberty to rename this.

Not everyone is interested in every kind of deltas (and some might
even be interested knowing which files do not have overrides), so this
here is an implementation of a --type=LIST... option for
systemd-delta, that makes it possible to filter what subset of deltas
we want.
The available modifiers are masked, equivalent, redirected, overriden,
and unchanged - they should be self explanatory, and the man page
explains them in a little more detail anyway.
As a side effect, in case of overriden files, the diff output was made
optional.
By default, everything is shown (with a diff, if appropriate) except
for completely unchanged files.
