It's fewer lines of code to get eliminate chdir usage than it is to keep using relative paths in most places. --- lib/PublicInbox/XapHelperCxx.pm | 19 +++++++------------ 1 file changed, 7 insertions(+), 12 deletions(-) diff --git a/lib/PublicInbox/XapHelperCxx.pm b/lib/PublicInbox/XapHelperCxx.pm index 1aa75f2a..17f988ee 100644 --- a/lib/PublicInbox/XapHelperCxx.pm +++ b/lib/PublicInbox/XapHelperCxx.pm @@ -60,17 +60,12 @@ sub build () { } require PublicInbox::CodeSearch; require PublicInbox::Lock; - require PublicInbox::OnDestroy; my ($prog) = ($bin =~ m!/([^/]+)\z!); my $lk = PublicInbox::Lock->new("$dir/$prog.lock")->lock_for_scope; write_file '>', "$dir/$prog.cpp", qq{#include "xap_helper.h"\n}, PublicInbox::Search::generate_cxx(), PublicInbox::CodeSearch::generate_cxx(); - opendir my $dh, '.'; - my $restore = PublicInbox::OnDestroy->new(\&chdir, $dh); - chdir $dir; - # xap_modversion may be set by needs_rebuild $xap_modversion //= xap_cfg('--modversion'); my $fl = xap_cfg(qw(--libs --cflags)); @@ -83,15 +78,15 @@ sub build () { $^O eq 'netbsd' and $fl =~ s/(\A|[ \t])\-L([^ \t]+)([ \t]|\z)/ "$1-L$2 -Wl,-rpath=$2$3"/egsx; my @xflags = split(' ', "$fl $xflags"); # ' ' awk-mode eats leading WS - my @cflags = grep(!/\A-(?:Wl|l|L)/, @xflags); - run_die([$cxx, '-c', "$prog.cpp", '-I', $srcpfx, @cflags]); - run_die([$cxx, '-o', "$prog.tmp", "$prog.o", @xflags]); - unlink "$prog.cpp", "$prog.o"; - write_file '>', 'XFLAGS.tmp', $xflags, "\n"; - write_file '>', 'xap_modversion.tmp', $xap_modversion, "\n"; + my @cflags = ('-I', $srcpfx, grep(!/\A-(?:Wl|l|L)/, @xflags)); + run_die([$cxx, '-o', "$dir/$prog.o", '-c', "$dir/$prog.cpp", @cflags]); + run_die([$cxx, '-o', "$dir/$prog.tmp", "$dir/$prog.o", @xflags]); + unlink "$dir/$prog.cpp", "$dir/$prog.o"; + write_file '>', "$dir/XFLAGS.tmp", $xflags, "\n"; + write_file '>', "$dir/xap_modversion.tmp", $xap_modversion, "\n"; undef $xap_modversion; # do we ever build() twice? # not quite atomic, but close enough :P - rename("$_.tmp", $_) for ($prog, qw(XFLAGS xap_modversion)); + rename("$dir/$_.tmp", "$dir/$_") for ($prog, qw(XFLAGS xap_modversion)); } sub check_build () {
