17 <h3><a name="TODO">TODO, 2009 - JSCoverage 0.5</a></h3>
18 <p>
19 JSCoverage 0.5 is available for <a href="http://siliconforks.com/jscoverage/download.html">download</a>.
20 </p>
21 <p>
22 This release contains a number of new features and bug fixes:
23 </p>
24 <ul class="list">
25 <li>
26 A new mode of operation, called "window mode", allows you to run code in a new browser window (or tab).
27 </li>
28 <li>
29 The method used to calculate overall percentage code coverage for all
30 files has changed. Previously, the calculation was done using an
31 unweighted average: each file's percentage code coverage contributed
32 equally to the total, regardless of the number of lines of code in the
33 file. Now, the calculation is done using a weighted average. This
34 fixes
35 <a href="http://siliconforks.com/jscoverage/bugs/6">bug #6</a> (thanks to
36 Liu Cougar).
37 </li>
38 <li>
39 Contiguous lines in the "Missing" column are now grouped together (thanks to
40 Liu Cougar).
41 </li>
42 <li>
43 The "Source" tab is no longer empty when code being tested throws an
44 uncaught exception
45 (fixing <a href="http://siliconforks.com/jscoverage/bugs/5">bug #5</a>)
46 </li>
47 <li>
48 Previously, certain uses of the <code>new</code> operator were
49 instrumented incorrectly; this has now been fixed
50 (thanks to Guillaume Lung).
51 </li>
52 <li>
53 The <code>jscoverage-server</code> program now allows more characters in
54 URLs (thanks to Guillaume Lung).
55 </li>
56 <li>
57 The <code>jscoverage-server</code> program now handles HTTP headers with
58 empty values (thanks to Velo).
59 </li>
60 <li>
61 The <code>jscoverage</code> program now refuses to instrument code which
62 has already been instrumented (thanks to Velo).
63 </li>
64 <li>
65 URLs containing spaces now work correctly (thanks to Igor Papkov).
66 </li>
67 <li>
68 Previously, on Windows, the <code>jscoverage</code> program
69 was unable to instrument a directory in a drive root; this has now been
70 fixed.
71 </li>
72 <li>
73 A limitation of 65,535 lines per file and 65,535 characters per line has
74 been removed.
75 </li>
76 <li>
77 Floating-point numbers are how handled with improved precision.
78 </li>
79 <li>
80 The <code>jscoverage-server</code> program can no longer bind to the same port multiple times on Windows.
81 </li>
82 <li>
83 Some bugs in <code>jscoverage-server</code>'s handling of the "chunked"
84 Transfer-Encoding have been fixed.
85 </li>
86 <li>
87 Compilation under Cygwin now uses the <code>-mno-cygwin</code> flag.
88 </li>
89 <li>
90 The wire format used for submitting coverage reports for storage by
91 <code>jscoverage-server</code> has changed. (This change will not have
92 any visible effects for most users; it will only be of interest to those
93 who have written code which parses that format.)
94 </li>
95 </ul>
96
97 <h3><a name="20081211">December 11, 2008 - JSCoverage 0.4</a></h3>
98 <p>
99 JSCoverage 0.4 is available for <a href="http://siliconforks.com/jscoverage/download.html">download</a>.
100 </p>
101 <p>
102 This release includes many new features:
103 </p>
104 <ul class="list">
105 <li>
106 The new <code>jscoverage-server</code> program is provided as an
107 alternative to the <code>jscoverage</code> program. The
108 <code>jscoverage-server</code> program is a simple HTTP server which
109 instruments JavaScript code as it is served; this allows you to execute
110 JavaScript and gather code coverage statistics without a preliminary
111 step of creating instrumented code. The <code>jscoverage-server</code>
112 program can either serve files directly from the filesystem or run as a
113 proxy server (with the <code>--proxy</code> option), instrumenting
114 JavaScript provided by another web server.
115 <li>
116 Using <code>jscoverage-server</code>, coverage reports can now be stored
117 to the filesystem.
118 </li>
119 <li>
120 JSCoverage now recognizes special JavaScript comments which specify that
121 certain lines of code should be ignored in coverage reports.
122 </li>
123 <li>
124 The new <code>--encoding</code> option provides better support for
125 different character encodings.
126 </li>
127 <li>
128 The JSCoverage user interface is now faster and more responsive.
129 </li>
130 <li>
131 The new <code>--no-highlight</code> option can be used to disable syntax
132 highlighting (giving better performance for large JavaScript files).
133 </li>
134 <li>
135 The build system has been modified so that <code>make install</code>
136 only installs the <code>jscoverage</code> and
137 <code>jscoverage-server</code> executables and their manual pages.
138 (Previous versions installed SpiderMonkey library and executable files,
139 which could conflict with other versions of SpiderMonkey installed on
140 your system.)
141 </li>
142 <li>
143 JSCoverage now supports several features beyond those found in the
144 <cite>ECMAScript Language Specification</cite>, including the following:
145 <ul class="list">
146 <li>getters and setters
147 <li><code>for each</code> loops
148 <li>generators and iterators
149 <li>the <code>let</code> keyword
150 <li>destructuring assignment
151 <li>array comprehensions
152 <li>expression closures
153 <li>generator expressions
154 </ul>
155 Use the new <code>--js-version</code> option to enable these features.
156 </li>
157 </ul>
158 <p>
159 The GCC C++ compiler (<code>g++</code>) is now required to compile
160 JSCoverage. (Previously, only the C compiler was needed.)
161 </p>
162 <p>
