Subversion tries to solve things in a 100% generic way, which may or may not match your requirements.</p> |

10,850,079 | 0 | <p>JavaScript knows <em>nothing</em> about the JSF code. Instead it knows everything about its generated HTML output. Look at the generated HTML output by rightclick page in browser and <em>View Source</em>. If you look closely, you'll see that the <code><p:selectOneMenu></code> doesn't generate a <code><select><option></code>, it instead generates a <code><div><ul><li></code>. The <code>disabled</code> attribute is only supported on <code><select></code>. Hence you don't see any effect.</p> <p>I suggest you to disable the thing via JSF ajax instead of via JavaScript. It's a matter of adding a <code><f:ajax></code> or <code><p:ajax></code> inside the dropdown and specifying the IDs of components which needs to be updated wherein the <code>disabled</code> check is been done based on the currently selected item. No need for JavaScript boilerplate anymore. This way you'll also take advantage of the robustness of server side validation.</p> <pre><code><p:selectOneMenu binding="#{searchType}" ...> <f:selectItem itemLabel="Search By Skill" itemValue="1" /> <f:selectItem itemLabel="Search By Location" itemValue="2" /> <p:ajax update="search type1" /> </p:selectOneMenu> <p:inputText id="search" ... disabled="#{searchType.value == 2}" /> <p:selectOneMenu id="type1" ... disabled="#{searchType.value == 1}"> ... </p:selectOneMenu> </code></pre> <hr> <p>By the way, the variable name "combo" is wrong. It's a dropdown, not a combobox. A combobox is an <strong>editable</strong> dropdown. The <code><p:selectOneMenu></code> doesn't render an editable dropdown, but just a dropdown.</p> |

35,424,427 | 0 | <blockquote> <ol> <li>What is <code>mk</code> returning?</li> </ol> </blockquote> <p>Let's go through a much simpler example In the documentation of GHC.Generics first. To achieve a generic function <code>encode :: Generic a => a -> [Bool]</code> that bit serialize every data type which has a Generic instance, they defined the type class below : </p> <pre><code>class Encode' rep where encode' :: rep p -> [Bool] </code></pre> <p>By defining <code>Encode'</code> instances for every Rep type (M1, K1, etc.), they made the function work universally on every data types.</p> <p>In <a href="https://ocharles.org.uk/blog/posts/2014-04-26-constructing-generically.html" rel="nofollow">Building data constructors with GHC Generics</a>, the author's final goal is a generic function <code>make :: Generic a => TypeOfConstructor a</code>, so naively one may define:</p> <pre><code>class Mk rep where mk :: (? -> p) -- what should '?' be? </code></pre> <p>And soon realize that it's impossible due to a few problems:</p> <ol> <li><code>-></code>, the function type in haskell only takes one argument at a time, so <code>mk</code> won't be able to return anything sensible if the constructor takes more than one argument.</li> <li>The number and type of the arguments are unclear: it's relative to the <code>rep</code> type in concern.</li> <li>It cannot be plain <code>p</code> as the result type. Without the <code>rep</code> context it's impossible to derive instances for <code>:*:</code> or <code>:+:</code>, and the function will no longer work on any nested data type.</li> </ol> <p>Issue 1 can be solved with Data.Functor.Compose. A function of type <code>a -> b -> c</code> can be encoded into <code>Compose ((->) a) ((->) b) c</code>, it can be further composed while keeps a whole lot of information about argument types. And by making it a type parameter of <code>Mk</code>, issue 2 is solved too:</p> <pre><code>class Functor f => Mk rep f | rep -> f where mk :: f (rep p) </code></pre> <p>where <code>f</code> is generalization over <code>Compose f g</code> and <code>(->) a</code>, which contains type-level information to construct a <code>rep p</code>, i.e. everything before the final <code>-></code> in <code>a -> b -> c -> ... -> rep p</code>. </p> <blockquote> <ol start="2"> <li>I'm guessing <code>Compose</code> comes from <code>Data.Functor.Compose</code>, which means that when I do <code>fmap f x</code>, it does the <code>fmap</code> two levels deep into the composed functors. But I can't make sense of the nested <code>fmap</code>s inside the <code>Compose</code>. </li> </ol> </blockquote> <p>In the <code>Mk</code> instance of <code>:*:</code>:</p> <pre><code>instance (Mk l fl, Mk r fr) => Mk (l :*: r) (Compose fl fr) where mk = Compose (fmap (\l -> fmap (\r -> l :*: r) mk) mk) </code></pre> <p><code>fmap</code> changes only the inner-most type of a nested Compose, in this case changes the final result of a n-ary function. <code>mk</code> here is literally concatenating two argument lists <code>fl</code> and <code>fr</code>, putting their results into a product type, namely</p> <pre><code>f :: Compose ((->) a) ((->) b) (f r) g :: Compose ((->) c) ((->) d) (g r) mk f g :: Compose (Compose ((->) a) ((->) b)) (Compose ((->) c) ((->) d)) ((:*:) f g r) -- or unwrapped and simplified (a -> b -> r) -> (c -> d -> r') -> a -> b -> c -> d -> (r, r') </code></pre> <blockquote> <ol start="3"> <li>For the instance of <code>M1 i c f</code>, I thought it would just wrap the inner values in <code>M1</code>, so the need to <code>M1 <$> mk</code> or <code>fmap M1 mk</code> makes no sense to me.</li> </ol> </blockquote> <p>It does just wrap the inner values in <code>M1</code>, but it's unclear how long the argument list of the underlying <code>f</code> is. If it takes one argument then <code>mk</code> is a function, otherwise it's a Compose. <code>fmap</code> wraps the inner-most value of them both.</p> |

Is it that your application works fine with few users, but starts throwing errors when under heavier load? If so, unit tests are not the answer. Unit tests != Load tests.</p> <p>If unit tests are in fact the answer, retrofitting unit tests is a good idea as it will help clean up the code. Just be prepared to refactor a lot. Code written with TDD turns out looking a lot different than code written without TDD. In my case, I had a method HandleDisposition() which took care of a lot of cases. This kind of method would not have existed if we had written the code with TDD. When retrofitting unit tests, we refactored that function and now have methods like XDisposition(), YDisposition(), ZDisposition(), which are a lot easier to write unit tests against.</p> |

3,344,788 | 0 | <p>There are a lot of other conditions that I've been hearing about with non-relational systems vs relational. I prefer this terminology over sql/no-sql as I personally think it describes the differences better, and several of the "no-sql" servers have sql add-ons, so anyway.... what sort of concurrency pattern or tranaction isolation is required in your system. One of the purported differences between rel and non-rel dbs is the "consistent-always", "consistent-mostly" or "consistent-eventually". Relation dbs by default usually fall into the "consistent-mostly" category and with some work, and a whole lot of locking and race conditions, ;) can be "consistent-always" so everyone is always looking at the most correct representation of a given piece of data. Most of what I've read/heard about non-rel dbs is that they are mainly "consistent-eventually". By this it means that there may be many instances of our data floating around, so user "A" may see that we have 92 widgets in inventory, whereas user "B" may see 79, and they may not get reconciled until someone actually goes to pull stuff from the warehouse. Another issue is mutability of data, how often does it need to be updated? The particular non-rel db's I've been exposed to have more overhead for updates, some of them having to regenerate the entire dataset to incorporate any updates.</p> <p>Now mind, I think non-rel/nosql are great tools if they really match your use case. I've got several I'm looking into now for projects I've got. But you've got to look at all the trade offs when making the decision, otherwise it just turns into more resume driven development.</p> |

15,276,750 | 0 | <p>By making the assumption that express middleware handling is not broken: Why don't you try to write an injection middleware that is responsible to inject the desired session data and place the injection middleware before your middleware function you want to test?</p> <p>With this approach you don't test client code directly but isolate the injection in your injection middleware.</p> |
