From 82a4f1a1a287d9dbf01156bc14ceb13ccbf16d7a Mon Sep 17 00:00:00 2001 From: Kevin Israel Date: Sat, 2 Nov 2013 15:47:24 -0400 Subject: Fix #66021 (Blank line inside empty array/object) Changed json_encode() so that when the JSON_PRETTY_PRINT option is specified, the pair of linefeeds immediately after an opening bracket and before the corresponding closing bracket is omitted when the array or object contains no elements or accessible properties (and hence would have a blank line between the brackets). --- ext/json/json.c | 18 ++++++++++-------- ext/json/tests/bug66021.phpt | 20 ++++++++++++++++++++ 2 files changed, 30 insertions(+), 8 deletions(-) create mode 100644 ext/json/tests/bug66021.phpt diff --git a/ext/json/json.c b/ext/json/json.c index 8c8963db8c..46f61d71ef 100644 --- a/ext/json/json.c +++ b/ext/json/json.c @@ -219,7 +219,7 @@ static inline void json_pretty_print_indent(smart_str *buf, int options TSRMLS_D static void json_encode_array(smart_str *buf, zval **val, int options TSRMLS_DC) /* {{{ */ { - int i, r; + int i, r, need_comma = 0; HashTable *myht; if (Z_TYPE_PP(val) == IS_ARRAY) { @@ -242,7 +242,6 @@ static void json_encode_array(smart_str *buf, zval **val, int options TSRMLS_DC) smart_str_appendc(buf, '{'); } - json_pretty_print_char(buf, options, '\n' TSRMLS_CC); ++JSON_G(encoder_depth); i = myht ? zend_hash_num_elements(myht) : 0; @@ -255,7 +254,6 @@ static void json_encode_array(smart_str *buf, zval **val, int options TSRMLS_DC) uint key_len; HashPosition pos; HashTable *tmp_ht; - int need_comma = 0; zend_hash_internal_pointer_reset_ex(myht, &pos); for (;; zend_hash_move_forward_ex(myht, &pos)) { @@ -272,11 +270,11 @@ static void json_encode_array(smart_str *buf, zval **val, int options TSRMLS_DC) if (r == PHP_JSON_OUTPUT_ARRAY) { if (need_comma) { smart_str_appendc(buf, ','); - json_pretty_print_char(buf, options, '\n' TSRMLS_CC); } else { need_comma = 1; } + json_pretty_print_char(buf, options, '\n' TSRMLS_CC); json_pretty_print_indent(buf, options TSRMLS_CC); php_json_encode(buf, *data, options TSRMLS_CC); } else if (r == PHP_JSON_OUTPUT_OBJECT) { @@ -291,11 +289,11 @@ static void json_encode_array(smart_str *buf, zval **val, int options TSRMLS_DC) if (need_comma) { smart_str_appendc(buf, ','); - json_pretty_print_char(buf, options, '\n' TSRMLS_CC); } else { need_comma = 1; } + json_pretty_print_char(buf, options, '\n' TSRMLS_CC); json_pretty_print_indent(buf, options TSRMLS_CC); json_escape_string(buf, key, key_len - 1, options & ~PHP_JSON_NUMERIC_CHECK TSRMLS_CC); @@ -307,11 +305,11 @@ static void json_encode_array(smart_str *buf, zval **val, int options TSRMLS_DC) } else { if (need_comma) { smart_str_appendc(buf, ','); - json_pretty_print_char(buf, options, '\n' TSRMLS_CC); } else { need_comma = 1; } + json_pretty_print_char(buf, options, '\n' TSRMLS_CC); json_pretty_print_indent(buf, options TSRMLS_CC); smart_str_appendc(buf, '"'); @@ -333,8 +331,12 @@ static void json_encode_array(smart_str *buf, zval **val, int options TSRMLS_DC) } --JSON_G(encoder_depth); - json_pretty_print_char(buf, options, '\n' TSRMLS_CC); - json_pretty_print_indent(buf, options TSRMLS_CC); + + /* Only keep closing bracket on same line for empty arrays/objects */ + if (need_comma) { + json_pretty_print_char(buf, options, '\n' TSRMLS_CC); + json_pretty_print_indent(buf, options TSRMLS_CC); + } if (r == PHP_JSON_OUTPUT_ARRAY) { smart_str_appendc(buf, ']'); diff --git a/ext/json/tests/bug66021.phpt b/ext/json/tests/bug66021.phpt new file mode 100644 index 0000000000..cf52e0c6df --- /dev/null +++ b/ext/json/tests/bug66021.phpt @@ -0,0 +1,20 @@ +--TEST-- +Bug #66021 (Blank line inside empty array/object when JSON_PRETTY_PRINT is set) +--SKIPIF-- + +--FILE-- + +--EXPECT-- +[ + [], + {}, + {} +] -- cgit v1.2.1
