* build: remove unnecessary distclean targetsLibravatar Kelvin M. Klann2023-07-20
| | | | This also fixes the duplicate execution of the "clean" targets.
* 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.

* build: standardize commands on top of makefilesLibravatar Kelvin M. Klann2023-06-21
| | | | To make the makefiles look more similar.
* CI: fix wrong matching for test errorsLibravatar Reiner Herrmann2022-07-30

* 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 }'
