2015-06-25install: make unit_file_get_list aware of UNIT_FILE_INDIRECTMichal Sekletar
Commit aedd401 introduced new unit file state, UNIT_FILE_INDIRECT. Unit file is said to have indirect state if it contains [Install] section which has only Also= directive. Thus, if enable of such unit file is requested then some other unit file gets enabled. Whether or not unit file is in indirect state can be determined by calling unit_file_can_install. Function unit_file_get_list populates list of unit files present in given lookup location. So far it did call unit_file_can_install in a way that would prevent finding out about unit files in indirect state. Such unit file would be incorrectly marked as static. Fixes following assertion in test-install, Assertion 'p->state == s' failed at src/test/test-install.c:59, function main(). Aborting. [1] 26868 abort (core dumped) ./test-install
2015-06-25install: explicitly return 0 on successMichal Sekletar
Maybe there is some left-over value stored in r from previous function call. Let's make sure we always return consistent error code when we reach end of the function body. Fixes following crash of test-install, Assertion 'r == 0' failed at src/test/test-install.c:52, function main(). Aborting. [1] 11703 abort (core dumped) ./test-install

2015-05-11install: when exporting prefix InstallInfo to become UnitFileInstallInfoLennart Poettering
All other types exported from install.h should be namespaces like this, hence namespace InstallInfo the same way. Also, remove external forward definition of UnitFileScope type.
2015-05-05core: rework unit name validation and manipulation logicLennart Poettering
A variety of changes: - Make sure all our calls distuingish OOM from other errors if OOM is not the only error possible. - Be much stricter when parsing escaped paths, do not accept trailing or leading escaped slashes. - Change unit validation to take a bit mask for allowing plain names, instance names or template names or an combination thereof. - Refuse manipulating invalid unit name

2015-03-14sysv-generator: initialize LookupPaths just onceZbigniew Jędrzejewski-Szmek
With debugging on, sysv-generator would print the full set of lookup paths for *every* sysv script. While at it, pass LookupPaths as a pointer in sysv-generator, and constify it everywhere.
2015-03-13tree-wide: there is no ENOTSUP on linuxDavid Herrmann
Replace ENOTSUP by EOPNOTSUPP as this is what linux actually uses.

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.
2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.

2014-12-19util: rename ignore_file() to hidden_file()Lennart Poettering
hidden_file() is a bit more precise, since dot files usually shouldn't be ignored, but certainly be considered hidden.

2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
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().
2014-11-10shared/install: when unit contains only Also=, report 'indirect'Jan Synacek
If a unit contains only Also=, with no Alias= or WantedBy=, it shouldn't be reported as static. New 'indirect' status shall be introduced. https://bugzilla.redhat.com/show_bug.cgi?id=864298
2014-10-31shared/install: avoid prematurely rejecting "missing" unitsDave Reisner
f7101b7368df copied some logic to prevent enabling masked units, but also added a check which causes attempts to enable templated units to fail. Since we know the logic beyond this check will properly handle units which truly do not exist, we can rely on the unit file state comparison to suffice for expressing the intent of f7101b7368df. ref: https://bugs.archlinux.org/task/42616

2014-10-23install, cgtop: adjust hashmap_move_one() callers for -ENOMEM possibilityMichal Schmidt
That hashmap_move_one() currently cannot fail with -ENOMEM is an implementation detail, which is not possible to guarantee in general. Hashmap implementations based on anything else than chaining of individual entries may have to allocate. hashmap_move_one will not fail with -ENOMEM if a proper reservation has been made beforehand. Use reservations in install.c. In cgtop.c simply propagate the error instead of asserting.
2014-10-23install: make InstallContext::{will_install,have_installed} OrderedHashmapsMichal Schmidt
It appears order may matter here. Use OrderedHashmaps to be safe.

This makes this function name similar to user_config_home() and makes it match the name of the environment variable.
2014-10-02add a transient user unit directorySteven Allen
This patch adds a transient user unit directory under `$XDG_RUNTIME_DIR/systemd/user/` and stores transient user-instance units (such as those created by `systemd-run --user`) under there instead of putting them in $XDG_CONFIG_HOME/systemd/user/.

2014-09-15hashmap: introduce hash_ops to make struct Hashmap smallerMichal Schmidt
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.
2014-08-27systemctl: fix broken list-unit-files with --rootLukas Nykryn
2014-08-26Revert "systemctl: fix broken list-unit-files with --root"Lennart Poettering
This reverts commit 41a451cc2901a5deb985aea4cc8de204a22e5612. This breaks checks for masking of units file, since we invoke null_or_empty_path() on the resulting path.
2014-08-25systemctl: fix broken list-unit-files with --rootLukas Nykryn
This patch modifies unit_file_get_list which will now return hashmap of structures where f->path is *without* root_dir prefix. This change should be ok, because current code either does not use root_dir at all or calls basename() on the f->path.

2014-08-20systemctl: fail in the case that no unit files were foundLukas Nykryn
Previously systemctl died with message -bash-4.2# systemctl --root /rawhi list-unit-files (src/systemctl/systemctl.c:868) Out of memory. in the case that no unit files were found in the --root or the directory did not exist. So lets return ENOENT in the case that --root does not exist and empty list in the case that there are no unit files.
2014-08-13util: allow strappenda to take any number of argsDave Reisner
This makes strappenda3 redundant, so we remove its usage and definition. Add a few tests along the way for sanity.

2014-07-31Reject invalid quoted stringsZbigniew Jędrzejewski-Szmek
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

2014-07-26Always check asprintf return codeKarel Zak
There is a small number of the places in sources where we don't check asprintf() return code and assume that after error the function returns NULL pointer via the first argument. That's wrong, after error the content of pointer is undefined.
2014-07-16test-tables: add new entriesZbigniew Jędrzejewski-Szmek
One missing string found. A few things had to be moved around to make it possible to test them.
2014-07-16Let config_parse open file where applicableZbigniew Jędrzejewski-Szmek
Special care is needed so that we get an error message if the file failed to parse, but not when it is missing. To avoid duplicating the same error check in every caller, add an additional 'warn' boolean to tell config_parse whether a message should be issued. This makes things both shorter and more robust wrt. to error reporting.

2014-06-20conf-files: include root in returned file pathsMichael Marineau
This restores the original root handling logic that was present prior to 112cfb18 when path expansion moved to path_strv_canonicalize_absolute. That behavior partially went away in 12ed81d9. Alternatively all users of conf_files_list* could be updated to concatenate the paths themselves as unit_file_query_preset did but since no user needs the un-concatenated form that is pointless duplication.
