I have experienced rare cases when visiting a particular URL where the Apache Server crashes on a fresh installation of Drupal 7.14 running WAMP on Windows XP or 7.
The common solution was to open the file causing the problem and re-save it. However, this did not explain why it was happening. Fortunately, I was able to consistently reproduce this problem when I installed the Internationalization module and visited admin/config/regional/language which would result in Apache crashing.
This information finally lead me to http://drupal.org/node/1562670
What I learned was it is actually a PHP 5.3.10 bug that triggers when processing include/require files with sizes that are exact multiples of 4096 bytes and causes PHP to segfault (!).
The reason why re-saving the files worked is because the line feeds in the file are re-formatted from \n (unix style) to \r\n (windows style) which changes the files size from the problematic value of 53248 (exactly 52 KB).
Having developed mostly in a MAMP environment, I have taken many things for granted. Today, while working with WAMP, I was pleasantly surprised by a “Fatal error: Call to undefined function: curl_init()”.
It took a few extra steps to get cURL working. WAMP comes preinstalled with many extensions, including cURL, but for some reason many are not enabled by default and enabling php_curl from within the WAMP menu did not solve my problem.
How to enable libcurl in WAMP
- Find and open c:\wamp\bin\php\php5.2.6\php.ini
- Uncomment ;extension=php_curl.dll
- Do the same for c\:wamp\bin\apache\apache2.2.8\bin\php.ini
- Restart WAMP and happy coding.
Still not working? A good place to start is check if Apache is loading the extension. Open both php.ini and make sure extension_dir is pointing to c:\wamp\bin\php\php5.2.6\ext
Recently I had to import a 3GB database into a local Drupal installation using WAMP in a Windows XP environment. The following method I found has consistently performed and requires very minimal setup.
All you need are:
- Access to command line (DOS), and
Note: the following examples assumes you have WAMP installed in c:\wamp and your SQL dump is in c:\dump
- First, launch command prompt via All Programs -> Accessories -> Command Prompt.
- Then run the MySQL command below to connect to your specified database:
C:\> c:\wamp\bin\mysql\mysql5.5.16\bin\mysql.exe -use databasename –u username -p password
- Lastly, run the following:
mysql> source c:\dump\my_database_dump.sql
