* tree-wide: remove Lennart's copyright linesLennart Poettering2018-06-141-4/+0
| | | | | | | | | | | These lines are generally out-of-date, incomplete and unnecessary. With SPDX and git repository much more accurate and fine grained information about licensing and authorship is available, hence let's drop the per-file copyright notice. Of course, removing copyright lines of others is problematic, hence this commit only removes my own lines and leaves all others untouched. It might be nicer if sooner or later those could go away too, making git the only and accurate source of authorship information.
* tree-wide: drop 'This file is part of systemd' blurbLennart Poettering2018-06-141-2/+0
| | | | | | | | | | | | | | | | This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.
* tree-wide: drop license boilerplateZbigniew Jędrzejewski-Szmek2018-04-061-13/+0
| | | | | | | | | | Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.

* tree-wide: remove Emacs lines from all filesDaniel Mack2016-02-101-2/+0
| | | | | This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
* journal: add dst_allocated_size parameter for compress_blobZbigniew Jędrzejewski-Szmek2015-12-131-5/+8
| | | | | | | | | | | | | | compress_blob took src, src_size, dst and *dst_size, but dst_size wasn't used as an input parameter with the size of dst, but only as an output parameter. dst was implicitly assumed to be at least src_size-1. This code wasn't *wrong*, because the only real caller in journal-file.c got it right. But it was misleading, and the tests in test-compress.c got it wrong, and worked only because the output buffer happened to be the same size as input buffer. So add a seperate dst_allocated_size parameter to make it explicit what the size of the buffer is, and to allow test to proceed with different output buffer sizes.
* tree-wide: never use the off_t unless glibc makes us use itLennart Poettering2015-09-101-5/+5
| | | | | | | | | | | off_t is a really weird type as it is usually 64bit these days (at least in sane programs), but could theoretically be 32bit. We don't support off_t as 32bit builds though, but still constantly deal with safely converting from off_t to other types and back for no point. Hence, never use the type anymore. Always use uint64_t instead. This has various benefits, including that we can expose these values directly as D-Bus properties, and also that the values parse the same in all cases.
* remove unused includesThomas Hindoe Paaboel Andersen2015-02-231-2/+0
| | | | | | 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.
* Fix misuse of uint64_t as size_tZbigniew Jędrzejewski-Szmek2014-08-031-12/+12
| | | | They have different size on 32 bit, so they are really not interchangable.
* journal: add LZ4 as optional compressorZbigniew Jędrzejewski-Szmek2014-07-061-9/+56
| | | | | | | | | | | | | | Add liblz4 as an optional dependency when requested with --enable-lz4, and use it in preference to liblzma for journal blob and coredump compression. To retain backwards compatibility, XZ is used to decompress old blobs. Things will function correctly only with lz4-119. Based on the benchmarks found on the web, lz4 seems to be the best choice for "quick" compressors atm. For pkg-config status, see http://code.google.com/p/lz4/issues/detail?id=135.
* coredump: make compression configurableZbigniew Jędrzejewski-Szmek2014-06-261-1/+1
| | | | | | | | | | | | Add Compression={none,xz} and CompressionLevel=0-9 settings. Defaults are xz/6. Compression=filesystem may be added later. I picked "xz" for the compression "type", since we might want to add different compressors later on. XZ is fairly memory and CPU intensive, and embedded users will likely want to use LZO or some other lightweight compression mechanism.
* journal/compress: add stream compression/decompression functionsZbigniew Jędrzejewski-Szmek2014-06-261-0/+4

* journal: by default do not decompress dat objects larger than 64KLennart Poettering2012-11-211-1/+1
| | | | | | | | | | This introduces a new data threshold setting for sd_journal objects which controls the maximum size of objects to decompress. This is relieves the library from having to decompress full data objects even if a client program is only interested in the initial part of them. This speeds up "systemd-coredumpctl" drastically when invoked without parameters.
* use #pragma once instead of foo*foo #define guardsShawn Landden2012-07-191-4/+1
| | | | | | | | | | | | | | | | | #pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers
* relicense to LGPLv2.1 (with exceptions)Lennart Poettering2012-04-121-4/+4
| | | | | | | | | | | | | | We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.
