Apache on XAMPP for Windows is mistakenly identifying files as executable

On my development machine, I am using XAMPP 1.8.1 with 

Apache/2.4.3 (Win32) OpenSSL/1.0.1c PHP/5.4.7
for testing projects. However, I have encountered an issue where I am unable to select Polish as a language option in both my personal project and the popular Bootstrap Datepicker component.

Upon investigation, I discovered that this problem arises when the browser attempts to load the locale file (general.pl.json for my project and bootstrap-datepicker.pl.js for the Bootstrap Datepicker), resulting in a 500 Internal Server Error from Apache.

After reviewing the Apache error.log, it appears that Apache is mistakenly trying to execute these files as scripts (possibly Perl): 

[win32:error] [pid 5128:tid 1680] [client 127.0.0.1:53455] AH02102: C:/XAMPP/htdocs/mobile/public/pg-demo-bootstrap/locales/general.pl.json is not executable; ensure interpreted scripts have "#!" or "'!" first line, referer: http://127.0.0.1/mobile/public/pg-demo-bootstrap/
[cgi:error] [pid 5128:tid 1680] (9)Bad file descriptor: [client 127.0.0.1:53455] AH01222: don't know how to spawn child process: C:/XAMPP/htdocs/mobile/public/pg-demo-bootstrap/locales/general.pl.json, referer: http://127.0.0.1/mobile/public/pg-demo-bootstrap/
[win32:error] [pid 5128:tid 1644] [client 127.0.0.1:53465] AH02102: C:/XAMPP/htdocs/us/ustv/assets/6dafd2fe/js/locales/bootstrap-datepicker.pl.js is not executable; ensure interpreted scripts have "#!" or "'!" first line, referer: http://127.0.0.1/us/ustv/content/manage/update.html?id=4
[cgi:error] [pid 5128:tid 1644] (9)Bad file descriptor: [client 127.0.0.1:53465] AH01222: don't know how to spawn child process: C:/XAMPP/htdocs/us/ustv/assets/6dafd2fe/js/locales/bootstrap-datepicker.pl.js, referer: http://127.0.0.1/us/ustv/content/manage/update.html?id=4

Despite numerous tests with different content and filenames, the issue persisted only with the presence of .pl in the filename.

Some key questions to address:

  1. Why does Apache identify these files as scripts despite having .pl in the middle of a filename ending with .js or .json?

  2. Why is Apache on Windows attempting to run Linux/Unix/Bash scripts and expecting characters like #! or '! at the beginning of the script?

An important question remains—how can this be resolved so that Apache recognizes these files as simple JavaScript files rather than attempting to execute them?

Answer №1

Within the configuration file xampp\apache\conf\httpd.conf, locate a line that resembles the following:

AddHandler cgi-script .cgi .pl .asp

To disable this handler, simply comment out the line like this:

#AddHandler cgi-script .cgi .pl .asp

After making this change, restart Apache. If you wish to maintain the .cgi and .asp handlers but remove the .pl handler, you can delete ".pl" from the line. Interestingly, Perl functionality will still be retained even with this modification.

Answer №2

Encountering the same issue, I found that the previous solution did not resolve the problem as expected. However, it directed me to the Apache documentation located at http://httpd.apache.org/docs/2.2/mod/mod_mime.html#addhandler. According to the documentation:

It is noted that filenames may have multiple extensions, and the extension argument will be compared against each of them.

Following the link for multiple extensions led me to a section on the same page that elaborates on how files can indeed have multiple extensions, such as welcome.fr.html being treated equivalently to welcome.html.fr. The sequence of extensions is inconsequential, and a filename could encompass multiple languages, like welcome.html.en.de. This approach allows for the inclusion of defined languages in the HTTP headers.

Configuration of handler based solely on final extension:

<FilesMatch \.pl$>
SetHandler cgi-script pl
</FilesMatch>

In order to make this adjustment effective, I needed to initially eliminate the handler assigned to pl:

RemoveHandler pl

Answer №3

When you encounter the message in the apache log that says:

apache: .js is not executable; ensure interpreted scripts have "#!"

The solution is to update the configuration file by using Alias instead of ScriptAlias. Follow this example:

Alias /bugzilla/ "C:/bugzilla/"

To fully resolve the issue, add the following snippet to the apache config file after the alias line:

<Directory "C:/bugzilla">
    ScriptInterpreterSource Registry-Strict
    AddHandler cgi-script .cgi
    Options +ExecCGI +FollowSymLinks
    DirectoryIndex index.cgi index.html
    AllowOverride Limit FileInfo Indexes Options AuthConfig
    Require all granted
</Directory>
