17 <h3><a name="20100923">September 23, 2010 - JSCoverage 0.5.1</a></h3>
18 <p>
19 JSCoverage 0.5.1 is available for <a href="http://siliconforks.com/jscoverage/download.html">download</a>.
20 </p>
21 <p>
22 This release contains several bug fixes and improvements:
23 </p>
24 <ul class="list">
25 <li>
26 Probably the largest change is in the documentation: the manual no
27 longer recommends using <code>file:</code> URLs.
28 It is recommended that an HTTP server be used instead.
29 (See the <a href="manual.html">manual</a> for details.)
30 The JSCoverage user interface now displays a warning when used with
31 <code>file:</code> URLs.
32 </li>
33 <li>
34 The <code>--verbose</code> option to <code>jscoverage</code> now
35 produces better output.
36 </li>
37 <li>
38 Report loading is now faster (thanks to Klaus).
39 </li>
40 <li>
41 Some bugs involving augmented object prototypes were fixed.
42 </li>
43 <li>
44 JavaScript instrumentation was improved to work better in non-browser
45 environments.
46 </li>
47 <li>
48 Some cases where permission errors were occurring in inverted mode were
49 fixed (thanks to tn).
50 </li>
51 <li>
52 Previously, if <code>jscoverage-server</code> was started with the
53 option <code>--ip-address=<var>A</var></code>, where <var>A</var> was a
54 specific IP address, it was impossible to shut it down with
55 <code>jscoverage-server --shutdown</code>.
56 This should be possible now by running
57 <code>jscoverage-server --shutdown --ip-address=<var>A</var></code>
58 from the same machine.
59 </li>
60 <li>
61 The test suite has been made more robust.
62 </li>
63 </ul>
64
65 <h3><a name="20100426">April 26, 2010 - New blog</a></h3>
66 <p>
67 If you would like to see some case studies showing how to use JSCoverage in practice, take a look at the new <a href="http://blog.siliconforks.com/">blog</a>.
68 This week there will be a series of articles about using JSCoverage with various JavaScript testing frameworks.
69 The <a href="http://blog.siliconforks.com/2010/04/26/jscoverage-scriptaculous/">first article</a> looks at using JSCoverage with the <a href="http://script.aculo.us">script.aculo.us</a> test suite.
70 </p>
71
72 <h3><a name="20100424">April 24, 2010 - JSCoverage 0.5</a></h3>
73 <p>
74 JSCoverage 0.5 is available for <a href="http://siliconforks.com/jscoverage/download.html">download</a>.
75 </p>
76 <p>
77 This release contains a number of new features and bug fixes:
78 </p>
79 <ul class="list">
80 <li>
81 A new mode of operation, called "window mode", allows you to run code in a new browser window (or tab).
82 </li>
83 <li>
84 Code coverage statistics can now be generated for applications based on
85 the Mozilla platform using the <code>--mozilla</code> option (thanks to
86 Murali Nandigama for help creating this).
87 </li>
88 <li>
89 The method used to calculate overall percentage code coverage for all
90 files has changed. Previously, the calculation was done using an
91 unweighted average: each file's percentage code coverage contributed
92 equally to the total, regardless of the number of lines of code in the
93 file. Now, the calculation is done using a weighted average. This
94 fixes
95 <a href="http://siliconforks.com/jscoverage/bugs/6">bug #6</a> (thanks to
96 Liu Cougar).
97 </li>
98 <li>
99 Contiguous lines in the "Missing" column are now grouped together (thanks to
100 Liu Cougar).
101 </li>
102 <li>
103 The "Source" tab is no longer empty when code being tested throws an
104 uncaught exception
105 (fixing <a href="http://siliconforks.com/jscoverage/bugs/5">bug #5</a>)
106 </li>
107 <li>
108 Previously, certain uses of the <code>new</code> operator were
109 instrumented incorrectly; this has now been fixed
110 (thanks to Guillaume Lung).
111 </li>
112 <li>
113 The <code>jscoverage-server</code> program now allows more characters in
114 URLs (thanks to Guillaume Lung).
115 </li>
116 <li>
117 The <code>jscoverage-server</code> program now handles HTTP headers with
118 empty values (thanks to Velo).
119 </li>
120 <li>
121 The <code>jscoverage</code> program now refuses to instrument code which
122 has already been instrumented (thanks to Velo).
123 </li>
124 <li>
125 URLs containing spaces now work correctly (thanks to Igor Papkov).
126 </li>
127 <li>
128 Previously, on Windows, the <code>jscoverage</code> program
129 was unable to instrument a directory in a drive root; this has now been
130 fixed.
131 </li>
132 <li>
133 Encoded URLs are now handled better in the query string.
134 </li>
135 <li>
136 A limitation of 65,535 lines per file and 65,535 characters per line has
137 been removed.
138 </li>
139 <li>
140 Floating-point numbers are now handled with improved precision.
141 </li>
142 <li>
143 The <code>jscoverage-server</code> program can no longer bind to the same port multiple times on Windows.
144 </li>
145 <li>
146 Some bugs in <code>jscoverage-server</code>'s handling of the "chunked"
147 Transfer-Encoding have been fixed.
148 </li>
149 <li>
150 Compilation under Cygwin now uses the <code>-mno-cygwin</code> flag.
151 </li>
152 <li>
153 The wire format used for submitting coverage reports for storage by
154 <code>jscoverage-server</code> has changed. (This change will not have
155 any visible effects for most users; it will only be of interest to those
156 who have written code which parses that format.)
157 </li>
158 </ul>
159
160 <h3><a name="20081211">December 11, 2008 - JSCoverage 0.4</a></h3>
161 <p>
162 JSCoverage 0.4 is available for <a href="http://siliconforks.com/jscoverage/download.html">download</a>.
163 </p>
164 <p>
165 This release includes many new features:
166 </p>
167 <ul class="list">
168 <li>
169 The new <code>jscoverage-server</code> program is provided as an
170 alternative to the <code>jscoverage</code> program. The
171 <code>jscoverage-server</code> program is a simple HTTP server which
172 instruments JavaScript code as it is served; this allows you to execute
173 JavaScript and gather code coverage statistics without a preliminary
174 step of creating instrumented code. The <code>jscoverage-server</code>
175 program can either serve files directly from the filesystem or run as a
176 proxy server (with the <code>--proxy</code> option), instrumenting
177 JavaScript provided by another web server.
178 <li>
179 Using <code>jscoverage-server</code>, coverage reports can now be stored
180 to the filesystem.
181 </li>
182 <li>
183 JSCoverage now recognizes special JavaScript comments which specify that
184 certain lines of code should be ignored in coverage reports.
185 </li>
186 <li>
187 The new <code>--encoding</code> option provides better support for
188 different character encodings.
189 </li>
190 <li>
191 The JSCoverage user interface is now faster and more responsive.
192 </li>
193 <li>
194 The new <code>--no-highlight</code> option can be used to disable syntax
195 highlighting (giving better performance for large JavaScript files).
196 </li>
197 <li>
198 The build system has been modified so that <code>make install</code>
199 only installs the <code>jscoverage</code> and
200 <code>jscoverage-server</code> executables and their manual pages.
201 (Previous versions installed SpiderMonkey library and executable files,
202 which could conflict with other versions of SpiderMonkey installed on
203 your system.)
204 </li>
205 <li>
206 JSCoverage now supports several features beyond those found in the
207 <cite>ECMAScript Language Specification</cite>, including the following:
208 <ul class="list">
209 <li>getters and setters
210 <li><code>for each</code> loops
211 <li>generators and iterators
212 <li>the <code>let</code> keyword
213 <li>destructuring assignment
214 <li>array comprehensions
215 <li>expression closures
216 <li>generator expressions
217 </ul>
218 Use the new <code>--js-version</code> option to enable these features.
219 </li>
220 </ul>
221 <p>
222 The GCC C++ compiler (<code>g++</code>) is now required to compile
223 JSCoverage. (Previously, only the C compiler was needed.)
224 </p>
225 <p>
226 Please report any bugs you find using the new <a href="http://siliconforks.com/jscoverage/bugs/">bug tracker</a>.
