* tree-wide: fixes for assorted grammar and spelling issuesZbigniew Jędrzejewski-Szmek2020-07-061-1/+1
| | | | Fixes #16363. Also includes some changes where I generalized the pattern.
* man: make separate "Errors" sections subsection of "Return value"Zbigniew Jędrzejewski-Szmek2019-03-211-15/+15
| | | | | | | | Logically, this is better, because we're describing a subset of possible return values. Visually this also looks quite good because groff renders refsect2 much less prominently. Also rewrap things, add <constant> in various places, fix some typos.
* man: use same header for all filesZbigniew Jędrzejewski-Szmek2019-03-141-2/+2
| | | | | | | The "include" files had type "book" for some raeason. I don't think this is meaningful. Let's just use the same everywhere. $ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n "http^gms' man/*.xml
* man: standarize on one-line license headerZbigniew Jędrzejewski-Szmek2019-03-141-1/+0
| | | | | | No need to waste space, and uniformity is good. $ perl -i -0pe 's|\n+<!--\s*SPDX-License-Identifier: LGPL-2.1..\s*-->|\n<!-- SPDX-License-Identifier: LGPL-2.1+ -->|gms' man/*.xml
* man: drop mode line in file headersZbigniew Jędrzejewski-Szmek2018-07-031-1/+1
| | | | | This is already included in .dir-locals, so we don't need it in the files themselves.

* sd-bus: also add destroy callbacks to sd_bus_track objectsLennart Poettering2018-06-071-17/+43
| | | | | This augments previous work for this for sd_bus_slot objects, and adds the same concept to sd_bus_track objects, too.
* bus: optionally call a callbacks for cleanupZbigniew Jędrzejewski-Szmek2018-06-061-0/+105
This adds a function sd_bus_slot_set_destroy_callback() to set a function which can free userdata or perform other cleanups. sd_bus_slot_get_destory_callback() queries the callback, and is included for completeness. Without something like this, for floating asynchronous callbacks, which might be called or not, depending on the sequence of events, it's hard to perform resource cleanup. The alternative would be to always perform the cleanup from the caller too, but that requires more coordination and keeping of some shared state. It's nicer to keep the cleanup contained between the callback and the function that requests the callback.
