如何调试看起来不能运行的Bugzilla扩展？

Question

我需要一些帮助让bugzilla扩展离开地面。

我想挂钩到bug_format_comment (仅供参考:当我提交到SVN时，将一些自动添加为注释的纯文本更改为指向相应SCM提交的链接。)

现在，当我手动向bug添加注释时，似乎什么都没有发生。

除了将扩展放在/extensions/my-ext-name/ dir中之外，我还需要做什么特殊的事情才能让它运行吗？我如何测试扩展是否被调用？

我使用的是旧版本的Bugzilla (3.2.x)。这个钩子支持吗？(我在文档中找不到该信息)。

下面是我的完整Extension.pm文件(我没有使用Perl的经验。我从example扩展中获取钩子的示例，并从那里运行)

package Bugzilla::Extension::Websvn-scmbug-autolink;
use strict;
use base qw(Bugzilla::Extension);
# This code for this is in ./extensions/Websvn-scmbug-autolink/lib/Util.pm
use Bugzilla::Extension::Websvn-scmbug-autolink::Util;
use URI::Escape;

our $VERSION = '0.01';

# See the documentation of Bugzilla::Hook ("perldoc Bugzilla::Hook" 
# in the bugzilla directory) for a list of all available hooks.
sub install_update_db {
    my ($self, $args) = @_;

}

sub bug_format_comment {
    my ($self, $args) = @_;


    my $regexes = $args->{'regexes'};
    # push(@$regexes, { match => qr/\bfoo\b/, replace => 'bar' });


# 6665 --> 6666
# CTUFramework:trunk/CTUCsharpRuntime/CtuFramework/text1-renamed.txt
    #my $bar_match = qr/\b(bar)\b/;
    my $bar_match = qr/(?:^|\r|\n)(\d+|NONE) (-->) (\d+|NONE)[ \r\n\t]+([^:]+):(.*?)[\r\n]/s; #/s - treat as single line
    push(@$regexes, { match => $bar_match, replace => \&_replace_bar });
    my $scm_match2 = qr/(?:^|\r|\n)(\d+|NONE) (-->) (\d+|NONE)[ \r\n\t]+([^:]+):(.*?)[\r\n]/s; #/s - treat as single line
    push(@$regexes, { match => $scm_match2, replace => \&_replace_bar });
}

# Used by bug_format_comment--see its code for an explanation.
sub _replace_bar {
    my $args = shift;

    my $scmFromVer = $args->{matches}->[0]; 
    my $scmToVer = $args->{matches}->[1];
    my $scmArrow = $args->{matches}->[2];
    my $scmProject = $args->{matches}->[3];
    my $scmFile = $args->{matches}->[4];
    # Remember, you have to HTML-escape any data that you are returning!
    my $websvnRoot = "http://devlinux/websvn";
    my $websvnRepo = uri_escape($scmProject); #maybe do a mapping
    my $websvnFilePath = uri_escape("/".$scmFile);

    my $fromRevUrl = sprintf("%s/revision.php?repname=%s&rev=%s", 
        $websvnRoot, $websvnRepo, $scmFromVer);
    my $toRevUrl =   sprintf("%s/revision.php?repname=%s&rev=%s", 
        $websvnRoot, $websvnRepo, $scmToVer);
    my $diffUrl =    sprintf("%s/diff.php?repname=%s&path=%s&rev=%s", 
        $websvnRoot, $websvnRepo, $websvnFilePath, $scmToVer);
    my $fileUrl =    sprintf("%s/filedetails.php?repname=%s&path=%s&rev=%s", 
        $websvnRoot, $websvnRepo, $websvnFilePath, $scmToVer);

    # TODO no link for 'NONE'
    my $fromRevLink = sprintf(qq{<a href="%s">%s</a>}, $fromRevUrl, $scmFromVer);
    my $toRevLink =   sprintf(qq{<a href="%s">%s</a>}, $toRevUrl, $scmToVer);
    my $diffLink =    sprintf(qq{<a href="%s">%s</a>}, $diffUrl, $scmArrow);
    my $fileLink =    sprintf(qq{<a href="%s">%s</a>}, $fileUrl, $scmFilePath);
    # $match = html_quote($match);
    return "$fromRevLink $diffLink $toRevLink:$fileLink";
};
__PACKAGE__->NAME;

Answer 1

我搜索了Bugzilla源代码，发现这个钩子在3.2.x版本中根本不受支持。钩子是在Bugzilla 3.6中引入的：http://bzr.mozilla.org/bugzilla/3.6/revision/6762

PS。我在模板脚本中修改了正则表达式以获取注释。听起来很奇怪，但很管用。

如前所述，您的扩展甚至不会加载:破折号在Perl包名称中是无效的。

将名称从Websvn-scmbug-autolink更改为Websvn_scmbug_autolink。
