* tree-wide: port to fd_wait_for_event()Lennart Poettering2020-06-101-13/+6
| | | | | | | | Prompted by the discussion on #16110, let's migrate more code to fd_wait_for_event(). This only leaves 7 places where we call into poll()/poll() directly in our entire codebase. (one of which is fd_wait_for_event() itself)
* tree-wide: check POLLNVAL everywhereLennart Poettering2020-06-101-1/+4
| | | | | | | | | | | | | poll() sets POLLNVAL inside of the poll structures if an invalid fd is passed. So far we generally didn't check for that, thus not taking notice of the error. Given that this specific kind of error is generally indication of a programming error, and given that our code is embedded into our projects via NSS or because people link against our library, let's explicitly check for this and convert it to EBADF. (I ran into a busy loop because of this missing check when some of my test code accidentally closed an fd it shouldn't close, so this is a real thing)

* libudev: hide definition of struct udev_list from other libudev componentsYu Watanabe2019-06-126-55/+101
| | | | | In the later commit, udev_list will be just a wrapper of hashmap or LIST. So, allocating udev_list does not increase much cost.

* sd-device-enumerator: support multiple parentsYu Watanabe2019-01-231-3/+0
| | | | | | | | | | | When sd_device_enumerator_add_match_parent() is called multiple times, then previously set parents are discarded. This adds device_enumerator_add_match_parent_incremental() to make sd-device-enumerator scan devices under all specified parents. Note that for backward compatibility, sd_device_enumerator_add_match_parent() and udev_enumerate_add_match_parent() still discard previous assignments.
* Remove 'inline' attributes from static functions in .c files (#11426)Topi Miettinen2019-01-151-1/+1
| | | Let the compiler perform inlining (see #11397).
* libudev-util: make util_replace_whitespace() read only len charactersYu Watanabe2019-01-031-6/+7
| | | | | | This effectively reverts df8ba4fa0e8be1ff7899d08a4b6be0196c8405a0. Fixes #11264.
* meson: simplify handling of pkgconfigdatadir=no, pkgconfiglibdir=noZbigniew Jędrzejewski-Szmek2018-12-211-4/+3
| | | | | | | | | | | The idea was that those vars could be configured to 'no' to not install the .pc files, or they could be set to '', and then they would be built but not installed. This was inherited from the autoconf build system. This couldn't work because '' is replaced by the default value. Also, having this level of control doesn't seem necessary, since creating those files is very quick. Skipping with 'no' was implemented only for systemd.pc and not the other .pc files. Let's simplify things and skip installation if the target dir is configured as 'no' for all .pc files.
* meson: define PROJECT_VERSION as the "bare" project versionZbigniew Jędrzejewski-Szmek2018-12-201-1/+1
| | | | | | | | | | | | | | Let's not use atoi() if we can simply provide the project version as a number. In C code, this is the numerical project version. In substitutions in other files, this is just the bare substitution. The "PACKAGE_" prefix is from autotools, and is strange. We call systemd a "project", and "package" is something that distros build. Let's rename. PACKAGE_URL is renamed to PROJECT_URL for the same reasons and for consistency. (This leave PACKAGE_VERSION as the stringified define for C code.)
* libudev: drop unnecessary checkZbigniew Jędrzejewski-Szmek2018-11-231-2/+0
| | | | sd_device_get_subsystem returns -ENOENT if subsystem is not set.

* tree-wide: use __ prefixed gcc attributes (#10843)Lennart Poettering2018-11-201-8/+8
| | | | | | | | | | As suggest here: https://gcc.gnu.org/onlinedocs/gcc/Attribute-Syntax.html#Attribute-Syntax "You may optionally specify attribute names with ‘__’ preceding and following the name. This allows you to use them in header files without being concerned about a possible macro of the same name. For example, you may use the attribute name __noreturn__ instead of noreturn. "
* udev: drop util_log_priority() and use log_level_from_string()Yu Watanabe2018-11-122-17/+0
| | | | | | The function util_log_priority() is almost same as log_level_from_string(). The difference between them is only that util_log_priority() accepts such that '3 hogehoge'.
* libudev: conserve previous behaviorYu Watanabe2018-11-121-0/+2
| | | | | | | | | The commit dcfbde3a43d632ff6e286c77e1081087eca59d8e changes sd_device_get_ifindex() returns -ENOENT instead of zero if the device does not have ifindex. Let's keep the original behavior of udev_device_get_ifindex(). Fixes #10699.

* tree-wide: add a single version of "static const int one = 1"Lennart Poettering2018-10-151-2/+1
| | | | | | | | | | All over the place we define local variables for the various sockopts that take a bool-like "int" value. Sometimes they are const, sometimes static, sometimes both, sometimes neither. Let's clean this up, introduce a common const variable "const_int_one" (as well as one matching "const_int_zero") and use it everywhere, all acorss the codebase.
