When I checked the Sources, Packages directory and the temp directory within it, all were writable by the owner, group, and others having file permissions of 777.
# ls -ldgG Sources Packages Packages/temp drwxrwxrwx. 4 84 Aug 23 13:54 Packages drwxrwxrwx. 2 6 Aug 23 13:54 Packages/temp drwxrwxrwx. 2 4096 Aug 22 22:28 Sources
The temp directory wasn't empty, but should have been, though,
since there were no packages pending installation. I deleted everything in
the temp directory and tried again, but received the same error
whenever I tried to upload or download the file. I thought I might have
created the problem when I previously deleted the zip file for the mod from
the Packages directory, so I copied the zip file back into the
Packages directory. I then received the following error message, instead,
when I tried to upload the zip file for the mod:
So I deleted the zip file I manually copied to the Packages directory. When I tried to download from a URL again, I was back at the original error message.
So I looked for the location of the file containing the error message.
$ grep -rwl "Although the package was downloaded" --include=*.php Themes/default/languages/Errors.english.php
I then examined the Themes/default/languages/Errors.english.php
file. The error message is stored at:
$txt['package_get_error_is_zero'] = 'Although the package was downloaded to the server it appears to be empty. Please check the Packages directory, and the "temp" sub-directory are both writable. If you continue to experience this problem you should try extracting the package on your PC and uploading the extracted files into a subdirectory in your Packages directory and try again. For example, if the package was called shout.tar.gz you should:<br />1) Download the package to your local PC and extract it into files.<br />2) Using an FTP client create a new directory in your "Packages" folder, in this example you may call it "shout".<br />3) Upload all the files from the extracted package to this directory.<br />4) Go back to the package manager browse page and the package will be automatically found by SMF.';
So then I needed to locate the PHP file that loaded the error message using
package_get_error_is_zero.
$ grep -rwl "package_get_error_is_zero" --include=*.php Sources/Subs-Package.php Sources/PackageGet.php Themes/default/languages/Errors.english.php
In Sources/PageGet.php, I found the following:
// To download something, we need a valid server or url.
if (empty($_GET['server']) && (!empty($_GET['get']) && !empty($_REQUEST['package'])))
fatal_lang_error('package_get_error_is_zero', false);In Sources/PageGet.php, I found that
package_get_error_is_zero ocurs in the function
getPackageInfo.
I also noticed that there were two files related to the httpBL mod I was
attempting to install in the Sources directory.
# ls -lgG Sources/httpBL* -rw-rw-rw-. 1 23217 Aug 23 11:56 Sources/httpBL_2_Config.php -rwxrwxrwx. 1 36502 Aug 23 11:56 Sources/httpBL_Subs.php
The time stamps on them showed they were created when I tried unsuccessfully installing the mod earlier today. I deleted both files.I then tried downloading the mod again, but received the original error message again.
When I looked for any other files created in the Sources
directory today, I saw the following:
# ls -algG Sources | grep "Aug 23" drwxrwxrwx. 2 4096 Aug 23 14:36 . drwxrwxrwx. 9 4096 Aug 23 13:58 .. -rw-rw-rw-. 1 37494 Aug 23 11:56 Admin.php~ -rw-rw-rw-. 1 75762 Aug 23 11:56 ManagePermissions.php~
There didn't seem to be anything left there that was created today that
would explain the problem, so then I began to wonder if the problem was in
the zip file itself. I had changed one of the files within the original
zip file for httpBL, so I tried downloading the original version instead.
I didn't have the problem with that file. Instead, I saw "The package has been
uploaded successfully". When I checked the Packages directory,
I saw that the zip file was placed there. There were no files in the temp
directory.
$ ls Packages backups httpBL_v2_5_1.zip index.php installed.list temp $ ls Packages/temp $ ls -lgG Packages/httpBL_v2_5_1.zip -rwxrwxrwx. 1 75727 Aug 23 14:56 Packages/httpBL_v2_5_1.zip
As a test, from the Package Manager page, I chose Browse Packages and deleted the httpBL package I had just downloaded. That deleted the zip file for the package from the Packages directory.
$ ls -lgG Packages total 4 drwxrwxrwx. 2 83 Aug 22 22:28 backups -rw-r--r--. 1 324 Apr 22 12:34 index.php -rwxrwxrwx. 1 0 Apr 22 12:34 installed.list drwxrwxrwx. 2 6 Aug 23 13:54 temp
I tried downloading the modified zip file I created from the same URL again. I received the original error message when I attempted to do so.
I had modified a file within the zip file as noted in http:BL Database Error and then recreated the zip file. I had done that on the Linux server on which the forum resides. I then took the original zip file from the developer of the mod, edited the same file on a Microsoft Windows system and recreated the zip file on that system. When I then used that new zip file, the problem went away and I was able to successfully install the mod.
