The `shell` option has been removed. Remove stale references.
This does NOT remove `shell none`-related code comments in:
- src/firejail/fs_lib.c (L433-L441)
- src/firejail/join.c (L415-L417)
Relates to #5196.
Suggested by #5891.
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

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.
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

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/' '{}')\" >'{}'"
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

This amends commit b406b2420 ("tests: Fix mixed space/tabs indentation",
2023-02-19) / PR #5674.
Note: This is the only profile in test/ that the commit changed:
$ git show --pretty= --name-only b406b2420 -- test/
test/fs/private-whitelist.exp
test/network/firemon-route.exp
test/profiles/test2.profile

This appears to be the only C file in the repository that uses spaces
for indentation.
Commands used to check for the above:
$ git grep '^ ' -- '*.c' '*.h'
Commands used to search and replace:
$ f=test/filters/namespaces.c; printf '%s\n' \
"$(sed 's/ /\t/g' "$f")" >"$f"
Note: The mmap call was aligned manually.
Added on commit 5116c1ced ("testing", 2022-12-24).
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.
