How to kick off a mule flow to read messages from a JMS queue using an HTTP endpoint

阅读更多关于 How to kick off a mule flow to read messages from a JMS queue using an HTTP endpoint

问题 I basically have two flows : HTTP Inbound endpoint receives batch XML, splits to individual pieces and stages it to a JMS queue. Reads the staged XMLs from the JMS queue and processes the messages. I need to control the execution of flow 2 above using a Rest call (i.e) flow 2 should run only when an HTTP inbound call is received. I am using Mule version 3.2.2 Here are the flows: <flow name="flow-stage-input"> <http:inbound-endpoint host="localhost" port= "8082" path= "test/order" exchange

阅读更多关于 How to pre-hook the gitflow hotfix finish?

问题 I think I am using the "https://github.com/nvie/gitflow", if that is the one which comes within the Smartgit GUI program. Every time I to commit something, I update the 'build' number. Example: 2.6.0-77 to 2.6.0-78 This is already implemented to hook the pre-commit and increment the build number, but how to create a hook to hook the gitflow hotfix finish and to increment the hotfix version number? Example: 2.6.0-70 to 2.6.1-70 The code to increment the hotfix version is already done. We just

Logcat continously shows messages

阅读更多关于 Logcat continously shows messages

问题 I don't know what's wrong. My logcat has been troubling me for two days. When device is connected to test, the logcat continuously gives messages though I don't run my app. If I run my app, I am unable to find my app logs in such a huge amount of data. Can someone suggest me to avoid this and so that I can only view my application's logs? Below is the logcat's flow which continously flows. I am testing with htc. 04-09 09:27:10.007: D/dalvikvm(843): GC_EXPLICIT freed 128K, 43% free 3530K/6151K

Mule flow execution unexpectedly splits on error in SMTP sendout

阅读更多关于 Mule flow execution unexpectedly splits on error in SMTP sendout

问题 I would like to catch errors from SMTP endpoint (for example in case it's misconfigured or the server is down) and when this happens, prevent messages from proceeding the normal path and rather go into an exception flow. An exception handler works and messages are routed into an exception flow. What is unexpected is that the message is duplicated and also proceeds with the "normal" flow as well. I would expect it to go only in one direction: if an email was sent successfully go into a normal

大多数网站通过检测浏览器参数来进行判断是不是selenium启动的浏览器，我们在利用selenium执行某些方法的同时，可能会造成某些参数出现（navigator.webdriver、无头里UA出现webdriver），所以写下这篇随笔，来尽可能地不被网站检测到。法一: 参考 https://stackoverflow.com/questions/33225947/can-a-website-detect-when-you-are-using-selenium-with-chromedriver 内高赞答案。网站会检测某个特殊参数$cdc_asdjflasutopfhvcZLmcfl，当然不止这一个，还有许多其余参数网上有许多人是通过mitmproxy来拦截请求进行修改参数的 import re from mitmproxy import ctx def response(flow): if '/js/yoda.' in flow.request.url: for webdriver_key in ['webdriver', '__driver_evaluate', '__webdriver_evaluate', '__selenium_evaluate', '__fxdriver_evaluate', '__driver_unwrapped', '__webdriver

How to make parallel outbound calls

阅读更多关于 How to make parallel outbound calls

问题 My use case requires to enrich my input with smne data and send it to an outbound endpoint. The data for enriching is obtained by making calls to two web-services and then extract the data from the reply. This extracted data is enriched into my input XML and sent to an outbound endpoint. The two web-service calls that I need to make needs to be parallel, as they don't have dependency on another. This way I could save my processing time. Please suggest how I could achieve this parallel

Min Cost Flow in R

阅读更多关于 Min Cost Flow in R

问题 Is there a package which implements a min cost flow algorithm in R? The igraph package seems only to have max flows (via the graph.maxflow() function), and nothing else here or on rseek.org looks helpful. 回答1: Perhaps you could return all flows and then sort by value? Package sna has a flowbet() function for flow between. 回答2: I was struggling with this as well and posted a question with a reproducible min-cost-flow problem here. While I did not receive a definite answer from the community, I
