Convert include-guard macro convention to avoid reserved identifiers Previously we used include-guards with names like _EVENT2_EVENT_H_. But C reserves macros beginning with an underscore for use by the system. This patch converts all include guards for files like include/event2/<fname.h> to be of form EVENT2_<FNAME_H>_INCLUDED_, and all Libevent 1.x headers in include/<fname.h> to be of the form EVENT1_<FNAME_H>_INCLUDED_, and all internal libevent headers with names like <fname.h> to the form <FNAME_H>_INCLUDED_. FNAME_H is here derived from fname.h by replacing every non-macro-usable character in fname.h with an underscore, and putting every remaining character in uppercase. This is an automatic conversion. The script that produced was made by running the following script over all header files: ===== #!/usr/bin/perl -w # Run this on every .h file except config.h, sys/queue.h, WIN32/event2/event-config.h use strict; my %macros = (); my %skipped = (); FILE: for my $fn (@ARGV) { my $f = $fn; if ($fn !~ /^\.\//) { $f = "./$fn"; } if ($f eq './config.h' or $f =~ m#/tree.h$# or $f =~ m#/queue.h# or $f =~ m#/event-config.h# or $f =~ m#/evconfig-private.h#) { $skipped{$fn} = 1; next FILE; } $skipped{$fn} = 0; open(F, $fn); while (<F>) { if (/^#ifndef ([A-Za-z0-9_]+)/) { $macros{$fn} = $1; next FILE; } } } print "#!/usr/bin/perl -w -i -p\n\n"; for my $fn (@ARGV) { if (!

Have all visible internal function names end with an underscore. We haven't had a convention for naming internal functions in -internal.h versus naming visible functions in include/**.h. This patch changes every function declared in a -internal.h file to be named ending with an underscore. Static function names are unaffected, since there's no risk of calling them from outside Libevent. This is an automatic conversion. The script that produced was made by running the following script over the output of ctags --c-kinds=pf -o - *-internal.h | cut -f 1 | sort| uniq (GNU ctags was required.) ===== #!/usr/bin/perl -w -n use strict;
