* build: use full paths on compile/link targetsLibravatar Kelvin M. Klann2024-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the compile commands clearer when building in parallel (with `make -j`) and ensures that `__FILE__` includes the full build-time path (relative to the root of the repository) whenever it is referenced, such as in failed assert() messages (currently the full path is only shown in errExit() messages). Example: Before: firejail: main.c:100: main: Assertion `1 == 2' failed. Error src/firecfg/main.c:100: main: malloc: Cannot allocate memory After: firejail: ../../src/firejail/main.c:100: main: Assertion `1 == 2' failed. Error ../../src/firecfg/main.c:100: main: malloc: Cannot allocate memory Commands used to search and replace: $ git grep -Ilz '^MOD_DIR =' -- '*Makefile' | xargs -0 -I '{}' \ sh -c "printf '%s\n' \"\$(sed -E \ -e 's|^MOD_DIR = src/(.*)|MOD = \\1\\nMOD_DIR = \$(ROOT)/src/\$(MOD)|' \ -e 's:^(PROG|SO) = [^.]+(\.so)?$:\\1 = \$(MOD_DIR)/\$(MOD)\2:' \ '{}')\" >'{}'" $ git grep -Ilz '^HDRS :=' -- '*.mk' | xargs -0 -I '{}' \ sh -c "printf '%s\n' \"\$(sed -E \ -e 's|wildcard (\*\..)|wildcard \$(MOD_DIR)/\\1|' '{}')\" >'{}'" Note: config.mk.in, src/fnettrace/Makefile and src/include/common.h were edited manually. This is a follow-up to #5871.

* Improve errExit error messagesLibravatar Kelvin M. Klann2023-06-28
| | | | | | | | | | | | | | | | | | | | | | | Changes: * Move msg to the end of errExit (right before perror(3p)) * Include the full file path (within the repository) * Add "()" to function name for clarity Before: Error malloc: main.c:123 main: Cannot allocate memory After: Error src/firejail/main.c:123 main(): malloc: Cannot allocate memory Note: This clarifies which is the exact file that the error message comes from, as there are many source files with the same name. For example: $ git ls-files 'src/*/main.c' | wc -l 20

* makefiles: rename common.mk to prog.mkLibravatar Kelvin M. Klann2022-11-21
| | | | | | | | | | | | For clarity, as it is included by the Makefiles that create programs and non-shared-objects, but not by the ones that create shared objects (see src/so.mk). Commands used to move and search and replace: $ git mv src/common.mk src/prog.mk $ git grep -IFlz 'common.mk' -- src | xargs -0 -I '{}' sh -c \ "printf '%s\n' \"\$(sed 's/common.mk/prog.mk/' '{}')\" >'{}'"
* makefiles: deduplicate many makefiles into common.mkLibravatar Kelvin M. Klann2022-11-21
| | | | | | | | | | The makefiles that both build C programs and include src/common.mk are nearly identical, save for the main target name and for any extra headers and objects that they might use. So move all of their (duplicated) code into src/common.mk, which (other than the "lib" target on src/lib/Makefile) leaves only variables and the includes of config.mk and src/common.mk in place.
* makefiles: deduplicate main target name into new PROG varLibravatar Kelvin M. Klann2022-11-21
| | | | | | | | | | Put the main target name into a new PROG variable, put PROG into a new TARGET variable, make "all" depend on `$(TARGET)` and replace every other occurrence of the main target name with `$(PROG)`. On the makefiles that build non-shared objects, to make them more similar. With this commit, all of their targets are identical (except for the extra "lib" target on src/lib/Makefile).
* makefiles: rename H_FILE_LIST and C_FILE_LISTLibravatar Kelvin M. Klann2022-11-21
| | | | | | | | | | | | | | | | | | | To HDRS and SRCS, respectively. To be more consistent with the OBJS variable. Misc: These names also appear to be more common from the makefiles that I've seen. Commands used to search and replace: git grep -IFlz -e H_FILE_LIST -e C_FILE_LIST -- src | xargs -0 -I '{}' sh -c "printf '%s\n' \"\$(sed \ -e 's/^H_FILE_LIST *=/HDRS =/' \ -e 's/\$(H_FILE_LIST)/\$(HDRS)/g' \ -e 's/^C_FILE_LIST *=/SRCS =/' \ -e 's/\$(C_FILE_LIST:/\$(SRCS:/g' \ '{}')\" >'{}'"
* makefiles: include config.mk directlyLibravatar Kelvin M. Klann2022-11-21
| | | | | | | Instead of including it through src/common.mk. This allows each makefile to directly override any value defined in config.mk.
* lib/Makefile: put all target before include of common.mkLibravatar Kelvin M. Klann2022-11-20
| | | | | | | | | | | | | | | | | | | The "all" target is usually intended to be the default one and when running make, the first target on a makefile is the one that gets built if no target is specified (such as when running `make` with no arguments). Also, note that unlike config.mk, src/common.mk may define its own targets, so move the "all" target to before the include of src/common.mk, to ensure that "all" keeps being the default target regardless of what is defined in src/common.mk. Note: If the "all" target is defined as depending directly on `$(OBJS)` while it is empty (that is, before src/common.mk is included), running `make` (or `make all`) will result in make always concluding that there is nothing to be done and exiting. So make "all" depend on an intermediary phony "lib" target instead, which in turn depends on `$(OBJS)` (and is declared after `$(OBJS)` is populated).

* makefiles: add generated files as dependenciesLibravatar Kelvin M. Klann2022-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the previous commit ("makefiles: stop failing when config.mk does not exist", 2022-06-23), make will not immediately fail when trying to build a target without having the proper compile-time flags (which are defined on common.mk). For example, when running the command below: make distclean && make It will throw an error only after (mis-)compiling multiple objects. So add a dependency on config.mk on every target that uses output variables (such as @NAME@ / $(NAME)) on its recipe. And add a dependency on config.sh on targets that call shell scripts that use output variables (such as @NAME@ / $NAME). Also, add a recipe for config.mk / config.sh telling to run ./configure, to make it a bit more obvious just in case. With this commit, make will abort earlier, by detecting that the config.mk / config.sh dependency does not exist. This happens before trying to execute the recipe. This also makes the dependencies more accurate, since if config.mk (which defines some CFLAGS) is changed, the CFLAGS may also have changed, so a target that uses CFLAGS should probably be considered out of date in this case anyway. Relates to #5140.
* build: reduce autoconf input files from 32 to 2Libravatar Kelvin M. Klann2022-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Configure summary: autoconf essentially only parses configure.ac and generates the configure script (that is, the "./configure" shell script). The latter is what actually checks what is available on the system and internally sets the value of the output variables. It then, for every filename foo in AC_CONFIG_FILES (and for every output variable name BAR in AC_SUBST), reads foo.in, replaces every occurrence of `@BAR@` with the value of the shell variable `$BAR` and generates the file foo from the result. After this, configure is finished and `make` could be executed to start the build. Now that (as of #5140) all output variables are only defined on config.mk.in and on config.sh.in, there is no need to generate any makefile nor any other mkfile or shell script at configure time. So rename every "Makefile.in" to "Makefile", mkdeb.sh.in to mkdeb.sh, src/common.mk.in to src/common.mk and leave just config.mk and config.sh as the files to be generated at configure time. This allows editing and committing all makefiles directly, without potentially having to run ./configure in between. Commands used to rename the makefiles: $ git ls-files -z -- '*Makefile.in' | xargs -0 -I '{}' sh -c \ "git mv '{}' \"\$(dirname '{}')/Makefile\"" Additionally, from my (rudimentary) testing, this commit reduces the time it takes to run ./configure by about 20~25% compared to commit 72ece92ea ("Transmission fixes: drop private-lib (#5213)", 2022-06-22). Environment: dash 0.5.11.5-1, gcc 12.1.0-2, Artix Linux, ext4 on an HDD. Commands used for benchmarking each commit: $ : >time_configure && ./configure && make distclean && for i in $(seq 1 10); do { time -p ./configure; } 2>>time_configure; done $ grep real time_configure | awk '{ total += $2 } END { print total/NR }'
* errno.c: fix reference to extract_errnos.sh in commentLibravatar Kelvin M. Klann2022-06-18
| | | | | | | See src/tools/extract_errnos.sh. Added on commit 081d1fbf2 ("Add seccomp errno filter support", 2015-09-23) / PR #66.
* makefiles: define root dir and include relative to itLibravatar Kelvin M. Klann2022-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A non-absolute path on an include command is always treated as being relative to the directory in which "make" was started in, rather than being relative to the makefile that contains the command. For example, given the following project structure and file contents: * Makefile: include src/foo.mk * src/foo.mk: include bar.mk * src/bar.mk: Running "make" on the root project directory (that is, where "Makefile" is) yields the following: src/foo.mk:1: bar.mk: No such file or directory As "bar.mk" in "include bar.mk" is relative to the current (process) directory (that is, "./bar.mk") and not to where foo.mk is located in ("./src/bar.mk"). So on every makefile that contains an include command, define the root project directory in the ROOT variable and always include relative to it, to later enable any included mkfiles to include other mkfiles without having to worry about the correct path. Commands used to search and replace: $ git grep -Flz 'include ../common.mk' -- src | xargs -0 -I '{}' sh -c \ "printf '%s\n' \"\`sed 's|include ../common.mk|ROOT = ../..\ninclude \$(ROOT)/src/common.mk|' '{}'\`\" >'{}'" Environment: GNU make 4.3-3.1 on Artix Linux
