27,409,557 | 0 | <p>Your math problem is right here:</p> <pre><code> writeStream.Write(buffer, 0, bytesRead); bytesRead = responseStream.Read(buffer, 0, Length); var progress = bytesRead * 100.0 / writeStream.Length; bw.ReportProgress((int)progress,SummaryText); </code></pre> <p>The return value from <code>responseStream.Read</code> is the number of bytes you read <em>in that one read</em>. It's not the total number of bytes read since you started reading from the file.</p> <p>Also, dividing the number of bytes read by the total number written (i.e. <code>writeStream.Length</code>) isn't telling you anything useful.</p> <p>If you want to update a progress bar, you have to know how many total bytes there are in the file, and how many total bytes you've read up to this point. So if the file is 1,000,000 bytes long, and you've read 450,000 bytes <em>total</em>, the progress would be 45% (i.e. 450000/1000000).</p> <p>In your code, you have to get the file size from the FTP server. That's the total number of bytes you're going to download. Then you need keep track of how many bytes you've read up to this point. The basic idea is:</p> <pre><code>int totalBytesToBeRead = ??; // somehow get length. responseStream.Length doesn't work. int totalBytesRead = 0; int bytesRead = -1; while (bytesRead != 0) { bytesRead = responseStream.Read(...); // now add to the total totalBytesRead += bytesRead; var progress = totalBytesRead * 100.0 / totalBytesToRead; } </code></pre> <h2>Update</h2> <p>The problem appears to be that <code>FtpWebRequest</code> doesn't supply a <code>ContentLength</code>, so you need some other way to get the length. The only thing that comes to mind is to request the length up front by doing a separate <code>FtpWebRequest</code> with the <code>GetFileSize</code> method. See <a href="http://stackoverflow.com/questions/4175874/get-file-size-on-an-ftp-in-c-sharp">Get File Size On An FTP in C#</a> for an example.</p> |

16,677,238 | 1 | Flattening an array in Flask API <p>I'm making an API with flask that takes as a POST message body a nested array, and then returns a list of the values. An example would be curl …. –d ”(([[1, [], [2, 3]], [[4]], 5])” would return [1,2,3,4,5]. The flattening script works in the command line, but when I POST to the API, I get some weird results. Code is here:</p> <pre><code>app = Flask(__name__) app.config.from_object(__name__) app.config.from_envvar('PHIGITAL_SETTINGS', silent=True) @lru_cache(maxsize=500) def flatten(l): flattened = [] for el in l: if isinstance(el, (list, tuple)): flattened.extend(flatten(el)) else: flattened.append(el) return flattened @app.route('/flatten', methods=['POST']) def flatten_api(): if request.method == 'POST': try: return jsonify({"response" : flatten(request.data)}) except Exception as e: return jsonify({"response" : "ERROR: %s" % str(e)}) if __name__ == '__main__': app.run() </code></pre> <p>Testing this in Postman gets me the response: { "response": [ "[", "[", "1", ",", " ", "[", "]", ",", " ", "[", "2", ",", " ", "3", "]", "]", ",", " ", "[", "[", "4", "]", "]", ",", " ", "5", "]" ] }</p> <p>Which is obviously not correct. I thought that it might have to do with the fact that request.data is a string, so I tried using ast.literal_eval to make request.data a list, but then I get the error "unhashable type: 'list'" when I try to call flatten on ast.literal_eval(request.data). I'm totally stumped and any help would be greatly appreciated.</p> <p>Also, is it possible in Flask to return just a value, rather than a key value pair? I'd rather return just [1,2,3,4,5] rather than {"response": [1,2,3,4,5]}</p> |

The log file shows "Error 0x80070642: Failed to perform minor upgrade of MSI package." <strong>EDIT</strong>: Inside the MSI log a SecureRepair fails with error code 39439E438 (?) probably because the stored hash value does not match the current... but that should be expected in a minor upgrade MSI, right?</p> <p>Are there recommended configurations between the Boostrapper and Setup WiX projects such that the small update, minor upgrade, and major upgrade use cases can be handled properly, or does the WiX Bootstrapper support ONLY major upgrades?</p> <p>I will continue to investigate and I'll post updates to my findings; </p> <p>Any hints are greatly appreciated, Thanks!</p> <p>Here are the source files which I barely changed from the WiX wizard generated code:</p> <p>--- Product.wxs ---</p> <pre><code><Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"> <Product Id="*" Name="SetupProject1 1.0.0.0" Language="1033" Version="1.0.0.0" Manufacturer="Acme" UpgradeCode="4c8a8cbf-e3d0-410c-8a8d-7e67eb4e7ff7"> <Package InstallerVersion="200" Compressed="yes" InstallScope="perUser" InstallPrivileges="limited" /> <MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." /> <MediaTemplate /> <Feature Id="ProductFeature" Title="SetupProject1" Level="1"> <ComponentGroupRef Id="ProductComponents" /> </Feature> </Product> <Fragment> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="LocalAppDataFolder"> <Directory Id="AcmeFolder" Name="Acme"> <Directory Id="INSTALLFOLDER" Name="WpfApplication1" /> </Directory> </Directory> </Directory> </Fragment> <Fragment> <ComponentGroup Id="ProductComponents" Directory="INSTALLFOLDER"> <Component Id="ProductComponent" Guid="8CA0B70F-39DA-4B4B-9104-46C58E26FCF4"> <CreateFolder/> <RemoveFolder Id="RemoveAcmeFolder" Directory="AcmeFolder" On="uninstall"/> <RemoveFolder Id="RemoveINSTALLFOLDER" On="uninstall" /> <RegistryValue Root="HKCU" Key="Software\Acme\WpfApplication1" Name="Version" Type="string" Value="[ProductVersion]" KeyPath="yes" /> <File Source="$(var.WpfApplication1.TargetPath)" KeyPath="no" /> </Component> </ComponentGroup> </Fragment> </code></pre> <p></p> <p>--- Bundle.wxs ---</p> <pre><code><Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:bal="http://schemas.microsoft.com/wix/BalExtension"> <Bundle Name="Bootstrapper1 1.0.0.0" Version="1.0.0.0" Manufacturer="Acme" UpgradeCode="e1092cbb-9134-42fc-a9f2-652f95f361fd"> <BootstrapperApplicationRef Id="WixStandardBootstrapperApplication.RtfLicense" /> <Chain> <MsiPackage Name="Acme Setup" SourceFile="$(var.SetupProject1.TargetPath)" Vital="yes" /> </Chain> </Bundle> </code></pre> <p></p> |

I find the best way to increase the efficiency of the client is to use the asynchronous socket functions provided. They're quite low-level and get rid of busy waiting and dealing with threads yourself. All of these have <code>Begin</code> and <code>End</code> in their method names. But first, I would try it using blocking, just so you get the semantics of HTTP out of the way. Then you can work on efficiency. Remember: Premature optimization is evil- so get it working, then optimize all of the stuff!</p> <p>Also: Some of your efficiency might be tied up in your use of <code>ToArray()</code>. It's known to be a bit expensive computationally. A better solution might be to store your intermediate results in a <code>byte[]</code> buffer and append them to a <code>StringBuilder</code> with the correct encoding.</p> <p>For gzipped or deflated data, read in all of the data (keep in mind that you might not get all of the data the first time you ask. Keep track of how much data you have read in, and keep on appending to the same buffer). Then you can decode the data using <code>GZipStream(..., CompressionMode.Decompress)</code>.</p> <p>I would say that doing this is not as difficult as some might imply, you just have to be a bit adventurous!</p> |

22,457,484 | 0 | <p>The size of the main undocked window cannot be modified by resizing it manually. It is sized so that it is exactly large enough to contain its children. So, you can do what you want by moving the component palette to the desired location. When you do so the main window will increase in size so that the component palette fits.</p> <p>Judging by your screenshot, your toolbars are drawn in a way to indicate that they are locked and cannot be dragged. That's not functionality that is present in the plain vanilla Delphi IDE, so I suspect that you have used functionality from either GExperts or CnPack to lock your toolbars. Obviously you'll need to unlock them in order to move them.</p> <p>Finally, I should point out that the inability to resize the main window vertically is not new. Classic Delphi versions (e.g. Delphi 7) behaved in exactly the same way. So I think that the fundamental issue is not related to a Delphi version upgrade, but rather is related to you having locked your toolbars.</p> |

7,894,221 | 0 | How to log into git bitbucket repository from jenkins <p>I have a GIT repository on bitbucket, which I want my Jenkins Server to access automatically. This is only possible using public/private key authentication. So I created a key pair and uploaded the public key to bitbucket. The public and the private key are on my server in the .ssh folder of the tomcat user running jenkins. I am able to clone my project when I am logged in as that user on the server.</p> <p>However I am unable to get jenkins to actually check out the code from bitbucket. It always says:</p> <pre><code>Permission denied (publickey). fatal: The remote end hung up unexpectedly </code></pre> <p>Well I assume that this happens because when accessing the repository over ssh I need to provide the passphrase for my private key and jenkins is unable to do this automatically. I read that it is possible to avoid beeing asked for the passphrase by providing a config file inside the .ssh folder containing the following content:</p> <pre><code>Host bitbucket.org IdentityFile ~/.ssh/id_dsa </code></pre> <p>I did so, but as soon as I provide that file I can no longer clone the repository from bitbucket. Not even directly from the server, getting the same error message as shown above.</p> <p>Did anyone manage to make this setup work? I also read the following thread here on stackoverflow that was of no use to me: <a href="http://stackoverflow.com/questions/6323434/how-do-i-set-a-private-ssh-key-for-hudson-jenkins-to-access-bitbucket">How do i set a private ssh key for hudson / jenkins to access bitbucket?</a> and I checked that tomcat really runs under user tomcat6 by creating an empty test project that simply runs "whoami". So I am pretty much out of ideas for fixing the problem.</p> |
