* sd-bus: store and compare per-module static origin idLuca Boccassi2023-04-251-1/+1
| | | | | | | | | sd-bus objects use hashmaps, which use module-global state, so it is not safe to pass a sd-bus object created by a module instance to another module instance (e.g.: when two libraries static linking sd-bus are pulled in a single process). Initialize a random per-module origin id and store it in the object, and compare it when entering a public API, and error out if they don't match, together with the PID.

* 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-Szmek2019-03-211-21/+21
| | | | | | | | 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.

* bus: optionally call a callbacks for cleanupZbigniew Jędrzejewski-Szmek2018-06-061-0/+1
| | | | | | | | | | | | | | | 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.
* man: also mention EINVAL in sd_bus_slot_set_floating(3)Zbigniew Jędrzejewski-Szmek2018-06-061-1/+7

* man: xinclude the generic text to talk about libsystemd pkgconfigZbigniew Jędrzejewski-Szmek2018-06-061-9/+2
| | | | | | | The only difference is that functions are not individually listed by name, but that seems completely pointless, since all functions that are documented are always exported, so the generic text tells the user all she or he needs to know.
* man: document the new sd_bus_slot_set_floating() callLennart Poettering2018-05-301-0/+118
Also extend the memory management description of sd-bus highlighting the effect of "floating" slot objects a bit.
