* fileio: automatically add NULL sentinel to parse_env_file()Lennart Poettering2018-11-141-4/+1
| | | | Let's modernize things a bit.
* fileio: drop "newline" parameter for env file parsersLennart Poettering2018-11-141-1/+1
| | | | | | | Now that we don't (mis-)use the env file parser to parse kernel command lines there's no need anymore to override the used newline character set. Let's hence drop the argument and just "\n\r" always. This nicely simplifies our code.
* tree-wide: uniformly bump RLIMIT_NOFILE in all our tools that access the journalLennart Poettering2018-10-161-0/+4
| | | | | | This makes use of rlimit_nofile_bump() in all tools that access the journal. In some cases this replaces older code to achieve this, and others we add it in where it was missing.
* journal-upload: check for overflowLennart Poettering2018-10-131-11/+11
| | | | CID 1394386
* journal-upload: fix off-by-one in assert()Zbigniew Jędrzejewski-Szmek2018-09-251-1/+1
| | | | CID #1394386.
* tree-wide: add clickable man page link to all --help textsLennart Poettering2018-08-201-4/+16
| | | | | | | | | | This is a bit like the info link in most of GNU's --help texts, but we don't do info but man pages, and we make them properly clickable on terminal supporting that, because awesome. I think it's generally advisable to link up our (brief) --help texts and our (more comprehensive) man pages a bit, so this should be an easy and straight-forward way to do it.
* Drop my copyright headersZbigniew Jędrzejewski-Szmek2018-06-141-3/+0

* tree-wide: beautify remaining copyright statementsLennart Poettering2018-06-141-1/+1
| | | | | | Let's unify an beautify our remaining copyright statements, with a unicode ©. This means our copyright statements are now always formatted the same way. Yay.
* 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.
* fileio: accept FILE* in addition to path in parse_env_file()Lennart Poettering2018-05-241-1/+1
| | | | | | | Most our other parsing functions do this, let's do this here too, internally we accept that anyway. Also, the closely related load_env_file() and load_env_file_pairs() also do this, so let's be systematic.
* tree-wide: drop spurious newlines (#8764)Lennart Poettering2018-04-191-2/+0
| | | | | | | | Double newlines (i.e. one empty lines) are great to structure code. But let's avoid triple newlines (i.e. two empty lines), quadruple newlines, quintuple newlines, …, that's just spurious whitespace. It's an easy way to drop 121 lines of code, and keeps the coding style of our sources a bit tigther.
* 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.
* journal-upload: make use of safe_close() where appropriateLennart Poettering2018-02-261-3/+1

* log: minimize includes in log.hLennart Poettering2018-01-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | log.h really should only include the bare minimum of other headers, as it is really pulled into pretty much everything else and already in itself one of the most basic pieces of code we have. Let's hence drop inclusion of: 1. sd-id128.h because it's entirely unneeded in current log.h 2. errno.h, dito. 3. sys/signalfd.h which we can replace by a simple struct forward declaration 4. process-util.h which was needed for getpid_cached() which we now hide in a funciton log_emergency_level() instead, which nicely abstracts the details away. 5. sys/socket.h which was needed for struct iovec, but a simple struct forward declaration suffices for that too. Ultimately this actually makes our source tree larger (since users of the functionality above must now include it themselves, log.h won't do that for them), but I think it helps to untangle our web of includes a tiny bit. (Background: I'd like to isolate the generic bits of src/basic/ enough so that we can do a git submodule import into casync for it)
* tree-wide: add DEBUG_LOGGING macro that checks whether debug logging is on ↵Lennart Poettering2017-12-151-1/+1
| | | | | | | (#7645) This makes things a bit easier to read I think, and also makes sure we always use the _unlikely_ wrapper around it, which so far we used sometimes and other times we didn't. Let's clean that up.
* journal-upload: remove duplication of --help and --version in help textMarcus Folkesson2017-12-031-2/+0
| | | | Signed-off-by: Marcus Folkesson <marcus.folkesson@gmail.com>
* Add SPDX license identifiers to source files under the LGPLZbigniew Jędrzejewski-Szmek2017-11-191-0/+1
| | | | | This follows what the kernel is doing, c.f. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5fd54ace4721fc5ce2bb5aef6318fcf17f421460.
* conf-parser: turn three bool function params into a flags fieldsLennart Poettering2017-11-131-1/+1
| | | | | This makes things more readable and fixes some issues with incorrect flag propagation between the various flavours of config_parse().
* tree-wide: make use of getpid_cached() wherever we canLennart Poettering2017-07-201-1/+1
| | | | | | | This moves pretty much all uses of getpid() over to getpid_raw(). I didn't specifically check whether the optimization is worth it for each replacement, but in order to keep things simple and systematic I switched over everything at once.
* tree-wide: fix wrong indent (#5757)Yu Watanabe2017-04-191-3/+3
| | | Fixes wrong indent introduced by the commit 43688c49d1fdb585196d94e2e30bb29755fa591b.
* Rename formats-util.h to format-util.hZbigniew Jędrzejewski-Szmek2016-11-071-1/+1
| | | | | | We don't have plural in the name of any other -util files and this inconsistency trips me up every time I try to type this file name from memory. "formats-util" is even hard to pronounce.
* tree-wide: drop NULL sentinel from strjoinZbigniew Jędrzejewski-Szmek2016-10-231-2/+2
| | | | | | | | | | | | | This makes strjoin and strjoina more similar and avoids the useless final argument. spatch -I . -I ./src -I ./src/basic -I ./src/basic -I ./src/shared -I ./src/shared -I ./src/network -I ./src/locale -I ./src/login -I ./src/journal -I ./src/journal -I ./src/timedate -I ./src/timesync -I ./src/nspawn -I ./src/resolve -I ./src/resolve -I ./src/systemd -I ./src/core -I ./src/core -I ./src/libudev -I ./src/udev -I ./src/udev/net -I ./src/udev -I ./src/libsystemd/sd-bus -I ./src/libsystemd/sd-event -I ./src/libsystemd/sd-login -I ./src/libsystemd/sd-netlink -I ./src/libsystemd/sd-network -I ./src/libsystemd/sd-hwdb -I ./src/libsystemd/sd-device -I ./src/libsystemd/sd-id128 -I ./src/libsystemd-network --sp-file coccinelle/strjoin.cocci --in-place $(git ls-files src/*.c) git grep -e '\bstrjoin\b.*NULL' -l|xargs sed -i -r 's/strjoin\((.*), NULL\)/strjoin(\1)/' This might have missed a few cases (spatch has a really hard time dealing with _cleanup_ macros), but that's no big issue, they can always be fixed later.
* tree-wide: introduce free_and_replace helperZbigniew Jędrzejewski-Szmek2016-10-171-3/+1
| | | | | | It's a common pattern, so add a helper for it. A macro is necessary because a function that takes a pointer to a pointer would be type specific, similarly to cleanup functions. Seems better to use a macro.
* tree-wide: rename config_parse_many to …_nulstrZbigniew Jędrzejewski-Szmek2016-09-161-1/+1
| | | | In preparation for adding a version which takes a strv.
* journal-upload: make watchdog state non-staticZbigniew Jędrzejewski-Szmek2016-04-061-1/+3
| | | | Also parse watchdog config when creating the Uploader object.
* journal-upload: Update watchdog while in curl_easy_performKlearchos Chaloulos2016-04-051-0/+1
| | | | It is observed that a combination of high log throughput, low I/O speed on journal remote side and many nodes uploading simultaneously caused the journal-upload process to dump core because of watchdog starvation. This is caused because journal-upload stays in curl_easy_perform(), because it cannot upload fast enough to reach the end of the journal. Currently journal-upload will return from curl_easy_perform() only when the end of the journal is reached. Therefore a check is added in journal_input_callback(), which will update the watchdog if the elapsed time since the start of the uploading process is greater than WATCHDOG_USEC/2.
* tree-wide: minor formatting inconsistency cleanupsVito Caputo2016-02-231-1/+1
|
* 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.
* defs: rework CONF_DIRS_NULSTR() macroLennart Poettering2015-11-101-1/+1
| | | | | | | | | | | | The macro is generically useful for putting together search paths, hence let's make it truly generic, by dropping the implicit ".d" appending it does, and leave that to the caller. Also rename it from CONF_DIRS_NULSTR() to CONF_PATHS_NULSTR(), since it's not strictly about dirs that way, but any kind of file system path. Also, mark CONF_DIR_SPLIT_USR() as internal macro by renaming it to _CONF_PATHS_SPLIT_USR() so that the leading underscore indicates that it's internal.
* util-lib: move CONF_DIRS_NULSTR definition to def.hLennart Poettering2015-11-031-0/+1
| | | | | | After all, this is not some compiler or C magic, but something very specific to how systemd works, hence let's move it into def.h, and out of macro.h
* util-lib: split out allocation calls into alloc-util.[ch]Lennart Poettering2015-10-271-0/+1
|
* util-lib: split out globbing related calls into glob-util.[ch]Lennart Poettering2015-10-271-0/+1
|
* util-lib: split string parsing related calls from util.[ch] into parse-util.[ch]Lennart Poettering2015-10-271-0/+1
|
* util-lib: split out fd-related operations into fd-util.[ch]Lennart Poettering2015-10-251-1/+2
| | | | | There are more than enough to deserve their own .c file, hence move them over.
* util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering2015-10-241-1/+2
| | | | | | | | | | | | | | string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.
* util: introduce common version() implementation and use it everywhereLennart Poettering2015-09-291-11/+9
| | | | | | This also allows us to drop build.h from a ton of files, hence do so. Since we touched the #includes of those files, let's order them properly according to CODING_STYLE.
* tree-wide: replace while(1) by for(;;) everywhereLennart Poettering2015-09-091-1/+1
| | | | Another Coccinelle script.
* tree-wide: port everything over to fflush_and_check()Lennart Poettering2015-07-291-9/+14
| | | | | | | | Some places invoked fflush() directly with their own manual error checking, let's unify all that by using fflush_and_check(). This also unifies the general error paths of fflush()+rename() file writers.
* everywhere: port everything to sigprocmask_many() and friendsLennart Poettering2015-06-151-4/+1
| | | | | | | | | | | This ports a lot of manual code over to sigprocmask_many() and friends. Also, we now consistly check for sigprocmask() failures with assert_se(), since the call cannot realistically fail unless there's a programming error. Also encloses a few sd_event_add_signal() calls with (void) when we ignore the return values for it knowingly.
* util: split out signal-util.[ch] from util.[ch]Lennart Poettering2015-05-291-1/+2
| | | | No functional changes.
* shared: add formats-util.hRonny Chevalier2015-04-101-0/+1

* Assorted format fixesZbigniew Jędrzejewski-Szmek2015-01-221-4/+4
| | | | | Types used for pids and uids in various interfaces are unpredictable. Too bad.
* journal-upload: enable curl debug output conditionallyZbigniew Jędrzejewski-Szmek2015-01-061-2/+3
| | | | https://bugs.freedesktop.org/show_bug.cgi?id=86464
* journal: install sigbus handler for journal tools tooLennart Poettering2015-01-051-6/+6
| | | | | | | | | | | | | This makes them robust regarding truncation. Ideally, we'd export this as an API, but given how messy SIGBUS handling is, and the uncertain ownership logic of signal handlers we should not do this (unless libc one day invents a scheme how to sanely install SIGBUS handlers for specific memory areas only). However, for now we can still make all our own tools robust. Note that external tools will only have read-access to the journal anyway, where SIGBUS is much more unlikely, given that only writes are subject to disk full problems.
* journald-remote,journal-upload: Support .d directories in the usual search pathsJosh Triplett2014-11-291-4/+4

* treewide: another round of simplificationsMichal Schmidt2014-11-281-4/+2
| | | | | Using the same scripts as in f647962d64e "treewide: yet more log_*_errno + return simplifications".
* treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt2014-11-281-2/+2
| | | | | | | | | | | If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
* treewide: simplify log_*_errno(r,...) immediately followed by "return r"Michal Schmidt2014-11-281-31/+18
|
* treewide: more log_*_errno() conversions, multiline callsMichal Schmidt2014-11-281-11/+10
| | | | | | | | | | | | Basically: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/log_(debug|info|notice|warning|error|emergency)\("([^"]*)%s"([^;]*),\s*strerror\(-?([->a-zA-Z_]+)\)\);/log_\1_errno(\4, "\2%m"\3);/gms;print;' \ $f; done Plus manual indentation fixups.
* treewide: no need to negate errno for log_*_errno()Michal Schmidt2014-11-281-6/+6
| | | | It corrrectly handles both positive and negative errno values.
