* 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
* build: move MAKEFLAGS to config.mk.inLibravatar Kelvin M. Klann2023-06-24
| | | | | | | To reduce the amount of boilerplate in the makefiles. This amends commit 9789c263a ("build: disable all built-in implicit make rules", 2023-06-21) / PR #5864.
* build: disable all built-in implicit make rulesLibravatar Kelvin M. Klann2023-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use `make -r` to reduce unnecessary filesystem lookups. Overall, this appears to reduce the amount of implicit rule searches by ~93.3% (~97.5% compared to a8f01a383) for the default build and by ~83.3% (~99.3% compared to a8f01a383) for the "man" target (as an example): $ git show --pretty='%h %ai %s' -s a8f01a383 2023-06-20 05:26:23 +0000 Merge pull request #5859 from kmk3/build-remove-retpoline $ ./configure >/dev/null $ make clean >/dev/null && make --debug=i -j 4 | grep -F 'Trying implicit' | wc -l 6798 $ make clean >/dev/null && make --debug=i -j 4 man | grep -F 'Trying implicit' | wc -l 1085 # (in the previous commit) $ make clean >/dev/null && make --debug=i -j 4 | grep -F 'Trying implicit' | wc -l 2535 $ make clean >/dev/null && make --debug=i -j 4 man | grep -F 'Trying implicit' | wc -l 42 # (with this commit applied) $ make clean >/dev/null && make --debug=i -j 4 | grep -F 'Trying implicit' | wc -l 170 $ make clean >/dev/null && make --debug=i -j 4 man | grep -F 'Trying implicit' | wc -l 7 Environment: GNU make 4.4.1-2 on Artix Linux. Note: According to make(1p) in POSIX.1-2017, "If .SUFFIXES does not have any prerequisites, the list of known suffixes shall be cleared.", while "The result of setting MAKEFLAGS in the Makefile is unspecified." Commands used to search and replace: $ git ls-files -z -- '*Makefile*' | xargs -0 -I '{}' sh -c \ "printf '%s\n' \"\$(sed -E \ 's/^(.SUFFIXES:)/\1\nMAKEFLAGS += -r\n/' '{}')\" >'{}'"
* build: disable most built-in implicit make rulesLibravatar Kelvin M. Klann2023-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clear `.SUFFIXES:` to reduce unnecessary filesystem lookups. Overall, this appears to reduce the amount of implicit rule searches by ~62% for the default build and by ~96% for the "man" target (as an example): $ git checkout master >/dev/null 2>&1 $ git show --pretty='%h %ai %s' -s a8f01a383 2023-06-20 05:26:23 +0000 Merge pull request #5859 from kmk3/build-remove-retpoline $ ./configure >/dev/null $ make clean >/dev/null && make --debug=i -j 4 | grep -F 'Trying implicit' | wc -l 6798 $ make clean >/dev/null && make --debug=i -j 4 man | grep -F 'Trying implicit' | wc -l 1085 # (with this commit applied) $ make clean >/dev/null && make --debug=i -j 4 | grep -F 'Trying implicit' | wc -l 2535 $ make clean >/dev/null && make --debug=i -j 4 man | grep -F 'Trying implicit' | wc -l 42 Environment: GNU make 4.4.1-2 on Artix Linux. Commands used to search and replace: $ git ls-files -z -- '*Makefile*' | xargs -0 -I '{}' sh -c \ "printf '%s\n' \"\$(sed '1s/^/.SUFFIXES:\n/' '{}')\" >'{}'" See also commit f48886f25 ("build: mark most phony targets as such", 2023-02-01) / PR #5637.
* Move usage text into usage_str varLibravatar Kelvin M. Klann2023-05-14
| | | | | | | | | | | | | | | For consistency and readability. Note: This also makes exactly one extra blank line be printed at the end of every usage text, which is currently only done in the following files: * src/fcopy/main.c * src/fnettrace-dns/main.c * src/fnettrace-icmp/main.c * src/fnettrace-sni/main.c * src/fnettrace/main.c * src/profstats/main.c
* Fix EOL at EOFLibravatar Kelvin M. Klann2023-02-19
| | | | | | | | | | | | | | | | | | Commands used to search and replace: $ git grep -Ilz '.' | xargs -0 -I '{}' sh -c \ "printf '%s\n' \"\$(cat '{}')\" >'{}'" The above commands ensure that there is exaclty 1 line terminator at EOF (rather than 0 or more than 1) on all non-empty text files. This fixes all of the "new blank line at EOF" errors raised by git: $ git diff --check 4b825dc642cb6eb9a060e54bf8d69288fbee4904..HEAD | grep '^[^+]' | cut -f 3 -d : | LC_ALL=C sort | uniq -c 21 new blank line at EOF. 72 space before tab in indent. 4 trailing whitespace.

* 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.
