X-Cart:To apply a patch manually

What is diff file?

Diff files consist of "hunks". Each "hunk" starts with a line like this:

@@ -942,8 +940,7 @@

where:

• 942 - indicates the number of the first line in the original code (before patch application)
• 8 - indicates the number of lines in the original code (before patch application)
• 940 - indicates the number of the first line in the changed code (after patch application)
• 7 - indicates the number of lines in the changed code (after patch application)

Then follows the file code that includes lines marked with the "+" and "-" signs. Lines marked with "+" are the lines that you need to add in the file to be patched. Lines marked with "-" are the lines that you need to remove from the file to be patched.

Under 'Index:' you will find the name of the file to be patched, for example:

Index: include/func/func.category.php

General instructions

1. Open the diff file in a text editor.

2. Edit the file (in our example, include/func/func.category.php):

• Find the lines marked with "-" in the text of the patch and remove them.
• Insert the lines marked with "+" in the text of the patch.

In our example, the original code (before applying the patch) would look like:

line 585:
line 586:    $cat = abs(intval($cat));
line 587:
line 588:    $to_search =
line 589:    $search_condition =
line 590:    $join_tbl = array();
line 591:
line 593:    $from = "$sql_tbl[categories] AS node ";
line 594:
...
line 942:        'c.rpos'
line 943:    );
line 944:
line 945:    $search_condition =
line 946:    $join_tbl = array();
line 947:
line 948:    if ($current_area == 'A' || $current_area == 'P') {
line 949:

Total lines: 9 and 8 in each hunk correspondingly.

The changed code (after applying the patch) would look like:

line 585:
line 586:    $cat = abs(intval($cat));
line 587:
line 588:    $to_search = $search_condition = $join_tbl = array();
line 589:
line 590:    $from = "$sql_tbl[categories] AS node ";
line 591:
...
line 940:        'c.rpos'
line 941:    );
line 942:
line 943:    $search_condition = $join_tbl = array();
line 944:
line 945:    if ($current_area == 'A' || $current_area == 'P') {
line 946:

Total lines: 7 and 7 in each hunk correspondingly.
