In the first example you are passing the output ofcat fileto the input ofls -l. Sincels -ldoes not take any input, it does not do anything regarding the output ofcat file. However in the second example you are using$(cat file)which puts the output ofcat filein the place of an argument passed tols -l, and this timels -lhas the text insidefilein the right place for doing something with it. The issue here is noticing the difference between the standard input of a program and the arguments of a program. Standard input is what you have when you callscanfin C, for example; and the arguments are what you get in theargvpointer passed as parameter to the main procedure.

This question already has answers here:Unix pipe into ls(3 answers)Closed7 years ago.I am a newbie to linux . I have been learning about cat command when i tried this .harish@harish-Lenovo-G50-45:~$ cat file
Videos/Arrow/Season*
harish@harish-Lenovo-G50-45:~$ cat file | ls -lThe command displays the content of the current folder instead of the folder mentioned in the file .. But when i did thisharish@harish-Lenovo-G50-45:~$ cat file
Videos/Arrow/Season*
harish@harish-Lenovo-G50-45:~$ ls -l $(cat file)The contents of the expected folder displays correctly . Why cant i not use the pipeline in this case ?

I believe you are installing the node modules usingnpm install, you also should save those module in yourpackage.jsonfile which you can do that bynpm install --save.The recommended best practice would be toSetup a Build Pipeline.There could be 3 stages or more:Build Stage: It builds the app so doing things likenpm installthere so your foldernode_modulesgets created for you.Test Stage: Tests the app so doing things likenpm testwould run all the tests in your appDeploy Stage: Once build and deploy stage runs successfully, Deploy will actually deploy the app to the Bluemix domain.

We're trying to deploy an AngularJS2 application to bluemix but we're missing the folder "node_modules" after the application was deployed to the server. We're using npm to build the application.I found the following post that is mentioning the problem: (https://developer.ibm.com/answers/questions/181207/npm-install-within-subdirectory-not-creating-node.html)My question would now be: what's the recommended best practice?

I am searching over parameters in pipeline usingGridSearchCVin Scikit.
I made my code work, but if I want to addclass_weights, I am hitting a wall.from sklearn.pipeline import Pipeline
RFC = RandomForestClassifier()
PCA = PCA()
pipe = Pipeline(steps=[('PCA', PCA), ('RFC', RFC)])
param_dict = {'RFC__n_estimators': [100,150],
'RFC__class_weights': [{0:1,1:2},{0:1,1:4}],
'PCA__n_components': [60,80]}
from sklearn.grid_search import GridSearchCV
estimator = GridSearchCV(pipe, param_dict, scoring='roc_auc')
estimator.fit(X_train, y_train)What is the proper way how to add this parameter to GridSearch?

Let's assume you're piping a string through bash:# this is your starting code
f() { tr -d [[:digit:]] | tr '[:upper:]' '[:lower:]' | tr -cd '[:alnum:]\nčšž'; }
# defining a test variable
s='hello123WORLD456'$'\n''čšž'
f <<<"$s" # writes "helloworld", a newline, then "čšž"...can trivially be changed by combining first and third, since they're both performing the same basic operation (deleting all characters in a given set -- even if in one of the two cases the set is defined in an exclusionary manner):# this behaves the same way
f() { tr '[:upper:]' '[:lower:]' | tr -cd '[:alpha:]\nčšž'; }...however, if running a modern bash release, you can do the same thing with a pair of parameter expansions, without any of the overhead of runningtrat all:s_lowercase=${s,,}
s_alpha=${s_lowercase//[![:alpha:]čšž]/}
echo "$s_alpha"
|
I use tr command 3 times sequentially in this case:tr -d [[:digit:]] | tr '[:upper:]' '[:lower:]' | tr -cd '[:alnum:]\nčšž'Is it possible to combine 3 tr commands in 1 tr command?
Or is there some way, how to do that faster?
|
Is it possible to combine more tr commands?
|
It is not that trivial, but you can do this:Get-ChildItem | foreach {$a = Get-Content $_
Set-Content $_ -Value "hi", $a}Tho to be honest i do think it matches your definition of a pipeline.
|
It's quite convenient to use Linux shell to append some content to a file, using pipe line operations and stream operations would do this.But in PowerShell, the pipeline is used in object level, not in file level. Then, how can I for example, insert a row "helloworld" to a list of files, to become their first line?

Regardless of having Forwarding, if you only have one port to access memory (e.g. unique Data & Instruction memory bus) and to simplify let's say there is no cache in the system (so every memory access needs to use the memory unit) then every instruction that needs the MEM stage to use the memory bus will generate a structural hazard, as the CPU won't be able to perform the FETCH and MEM stages in parallel because they both need to access memory.If instead you have two ports to access memory (e.g, one for Instructions and another for data), then the structural hazard noted above will be avoided as each memory-access stage will use its own bus+memory.

The error messages from scripts 1..4 shouldn't vanish down a black hole; you only redirected their standard output as the files given todiff.For example, given these files:$ cat script1
#!/bin/bash
echo $0 stdout
echo $0 stderr >&2
$ cat script2
#!/bin/bash
echo $0 stdout
cat -
echo $0 stderr >&2
$ cat script3
#!/bin/bash
echo $0 stdout
echo $0 stderr >&2
$ cat script4
#!/bin/bash
echo $0 stdout
cat -
echo $0 stderr >&2
$The output from your command line is:$ diff <(script1 | script2) <(script3 | script4)
./script1 stderr
./script3 stderr
./script2 stderr
./script4 stderr
1,2c1,2
< ./script2 stdout
< ./script1 stdout

Using the answer found inHow can you diff two pipelines in Bash?I have written some shell scripts that I want to compare the output of:diff <(script1 | script2) <(script3 | script4)However, any errors printed to STDERR in any of the scripts in the subshell pipelines disappear.

So, you have two types of users in your app:1. User
2. CordovaUserYou need two different links for two different users and somehow you should know in the pipeline that one of them isCordovaUser.First, in your settings, do this:FIELDS_STORED_IN_SESSION = ['user_type']then the links will look like this:1. <a href="{% url 'social:begin' 'facebook' %}">Login as User</a>
2. <a href="{% url 'social:begin' 'facebook' %}?user_type=cordova">Login as CordovaUser</a>then customizecreate_userto look something like this:def create_user(strategy, details, user=None, *args, **kwargs):
if user:
return {'is_new': False}
fields = dict((name, kwargs.get(name) or details.get(name))
for name in strategy.setting('USER_FIELDS',
USER_FIELDS))
if not fields:
return
user_type = strategy.session_get('type')
if user_type != 'cordova':
return {
'is_new': True,
'user': strategy.create_user(**fields)
}
else:
return {
'is_new': True,
'user': create_cordova_user(**fields)
}then, create thatcreate_cordova_usermethod and you are done.Hope this helps!

You just need to escape the\:std::string cmd = "awk -F\\| '{ var1=$2; var2=$5; print var1, var2 }' 1.txt";
//-----------------------^When you create your C++ string,\is treated as an escape character, unless you escape it.Alternatively in this case, you could just quote the delimiter, avoiding the need to escape it:std::string cmd = "awk -F'|' '{ print $2, $5 }' 1.txt";I assume that your script may be more complex that this in reality but I simplified it for you anyway, in case that helps.A final option, using raw string literals (which are supported in C++11):std::string cmd = R"awk -F\| '{ print $2, $5 }' 1.txt";TheRprefix means that the\is no longer interpreted as an escape character.

what about adding thePersonitem as a field for theAnotherPerson?. Remember you could always use themetaparameter on the requests to pass information between callbacks.You could do something like:parse_person(self, response):
...
yield Request(self, url=someurl, callback=parse_anotherperson,
meta={"some_key":"some_person_id"})Then you could add a reference to the previousPersonon yourAnotherPersonitem as a field or something else.

I use scrapy in order to scrape a social network and then get the data in a NEO4J database.My challenge here is to relate 2 items each other:class person(scrapy.Item):
name=Field()
class AnotherPerson(scrapy.Item):
name=Field()I want to save those two items in my graph database by saying:Person has relationship with AnotherPerson()What I need here is to send two items in ONE pipeline !! How can we do this ?
I tried to send it through a list, but scrapy doesn't accept the list as soon as a collection is in there.Here is my pseudo code:I get a list of person (each person has profile and a list of firends like facebook)For each person in this list:I open his profile (through a request and send the response to a
callback)I take the response and create a item: Person() and fill itI send the item with a "yield"Then I open his list of friend (through a request and send the
response to a another callback)I have the friend list pageThen For each friend in this list (the page display a name and a
city):create an item: AnotherPerson()I fill this item with the name and the cityI send the item with a "yield"I have two pipelines. They work well to save the data in database, but I don't have any clue to how I can relate them because for that I need to do that in the same process (ie. pipeline).I'm not sure if I've been clear, so don't hesitate to ask for clarifications.

Perhaps you needteecommand. You can use it to "fork the pipe", which means that an output
file could be created after a specific pipe input command. It is very useful when looking for errors.
For example:cat access.log | some filter commands | tee out01.txt \
| some other filter | tee ou02.txt | ./your_script > summary.csvMore exampleshere.
|
I'm at a bit of a loss on how to proceed with the task of piping log file contents to a csv file based on certain criteria.
Essentially, the problem is something like this:Write a script that receives http logs (or any arbitrary .log file) via pipe
input, and outputs a summarized csv in the number of hits per url per day.Example: executing the pipe commandcat access.log|some filter commands|./your_script > summary.csvcreates a text file called summary.csv with the content:" Action and path. 2015-01-01, 2015-01-02. 2015-01-03GET /index.php, 34, 53, 65POST /administrator, 32, 59, 39..."and so forth.The problem I'm facing at the moment is figuring out how to identify and execute specific parts of the pipe input command, and apply filters, before feeding it to the output pipe.
From what I'm familiar with, an array of command parameters (such as "cat", "gedit", ">", "|", etc) might work, but this leaves the problem of identifying them and executing them as a pipe command would, instead of just one after the other.I've searched quite thoroughly, but as yet found nothing even remotely helpful, aside from the suggestion to divide the pipe command into separate instructions and execute them one by one.
If anyone can suggest an easier and more effective way to do this, or any advice on this particular problem, it'd be much appreciated. Thanks in advance.

I suppose the best explanation is in your textbook, StackOverflow is a little narrow to go into in-depth explanations, but anyhow -A pipeline is simply a way to break down a chain of tasks into sequential steps. A pipelined CPU has special latches between the steps that synchronize with the clock, so that on every clock cycle, each of the steps can perform its task, and send the results to the next one. The big benefit from pipelining comes from the fact that once you fed the first element into the pipe (be that an instruction, or a bag of laundry, or whateve), the next cycle it's free to accept the next one, long before the previous elements finished the complete datapath (as a multi-cycle MIPS would do).This allows you, in a steady-state, to feed one element into the pipe per cycle, assuming no control/data hazards are detected. Therefore, the peak throughput of the machine remains 1 element per cycle (IPC=1 in the CPU nomenclature), while you have virtually no restriction on the length of the cycle! Theoretically, you can divide the work into more stages that are simpler and shorter, and shorten the cycle time (raising frequency, and overall throughput of work per time).Of course there are limits, as the CPU industry has discovered not so long ago - once the pipe becomes too large, the penalty of a flushes (we ignored earlier) become a huge penalty, so it's not all roses. Finding the sweetspot of depth and complexity is basically the key point in pipeline design.
|
What does it mean to have a pipelined datapath in MIPS architecture?All the examples I have read include doing laundry and waiting for certain tasks to finish, before moving on to other ones are fairly simple to comprehend.I was hoping for a more in depth technical explanation of how exactly a pipelined datapath helps MIPS architecture run faster and how stalls work.
|
Pipelined Datapath
|
We'd need to have the full datapath details from your textbook or assignment (I assume) to be sure. Here are some possibilities:Thesubinstruction stalls for 2 cycles before entering Execute, because it needs to wait for thelwresult to finish WritebackTheaddinstruction stalls untilsubis finished Writeback, again because it's waiting for a result.The detail that's relevant to both of these possibilities is when results from a given instruction become available to later dependent instructions. Does your datapath have register bypass of some sort? Are results in Writeback available the same cycle, or the next?
|
I'm trying to understand how the following MIPS code in a pipelined datapath would execute.lw $4, 100($2)
sub $6, $4, $3
add $2, $3, $5The MIPS instruction set has 5 stages (fetch, decode, execute, memory access, write back).The answer is: 8 cycles but I'm having difficulty understanding why. Here is what the pipeline could look like (incomplete).C F D E M WB
1 lw
2 sub lw
3 add sub lw
4 add sub x lw
5 add sub lw
6 add sub
7
8Questions: Why the x (stall?) at 4 and 5? How do I come up with the cycles including 7 and 8?
|
MIPS pipeline cycles
|
we are not supposed to do your homework.
if you assume that you can split the operations evenly into 5 stages and data dependencies are ignored, then the speedup would be 800/(160+40)=4
|
Calculating the maximum speedup of a single cycle CPU converted into a 5 stage pipelined CPU.Single cycle has a time of 800psThe pipelined stages are separated by registers that take time 40ps.What I have so far is:800/(40*5) = max speedup of 4.I'm not sure if I'm going about this correctly.

What @David said, using an iframe would probably do what you want. In that vain you can detect if you're in an iframe withvar isInIFrame = function() {
return window != window.top;
};I use that the change my CSS depending on if I'm in an iframe or notvar updateCSSIfInIFrame = function() {
if (isInIFrame()) {
document.body.className = "iframe";
}
};Then I can use CSS to change formatting. eg:/* only applies if in an iframe assuming the function above was called. */
body.iframe {
width: 100%;
height: 100%;
margin: 0px;
padding: 0px;
overflow: hidden;
}
.iframe>canvas {

I am doing some work with Pipeline Pilot and noticed that all of the built in HTML components that do things, like collapsible panels, tabs, or anything else that presumably has some javascript that I can't access causes my otherwise working WebGL component to break on load.Is there a way to "sandbox" or otherwise isolate a WebGL component for it's own protection? Weird question, and not the best way to look at it, but I can't change any of the code inside of the WebGL component, and I can't change any of the internal Pipeline Pilot code, so I need an inelegant solution of any kind.

You can use -ErrorVariable without a Try-Catch construct and even without -ErrorAction.
So, for example, you could do this :Get-ADUser -Filter {Enabled = 'False'} -Properties Modified -ErrorVariable Get-ADuserErr |`
Where Modified -LT (Get-Date).AddDays(-30) -ErrorVariable Where-ObjectErr |`
Remove-ADUser -Confirm:$false -ErrorVariable Remove-ADuserErr
If ($Get-ADuserErr) {
Write-Output $Get-ADuserErr }
If ($Where-ObjectErr) {
Write-Output $Where-ObjectErr }
If ($Remove-ADuserErr) {
Write-Output $Remove-ADuserErr }That way you have a different variable to store the error of each command and you get the default error handling behaviour (from $ErrorActionPreference , which is "Continue" by default).Also, your error variables ($Get-ADuserErr, $Remove-ADuserErr, etc...) are objects which can be piped to Out-File to log the errors into a file.Even nicer, these error variables are object of the type "ErrorRecord" which have a number a properties like : TargetObject, Exception, InvocationInfo, fullyQualifiedErrorID, etc...
So you can further manipulate you error variables objects to log exactly what you want.

I was wondering if someone would be able to give me some tips on handling non terminating errors through the pipeline?
Here is an example of what i would like to do.Get-ADUser -Filter {Enabled = 'False'} -Properties Modified | Where Modified -LT (Get-Date).AddDays(-30) | Remove-ADUser -Confirm:$falseBasically find all users that are disabled where the last modified time stamp is less than 30 days ago and delete them.
So what i'm looking for is how to handle and error if one where to occur so that it could be loggedI thought of using try catch, but if an error occurs then the entire command stops. I want it to be a non terminating error, so that it will continue to process all the users that it find, but then have a way to see if there where any error so that i can log themAny suggestions?

See all instructions in a single cycle non pipelined structure do not necessarily take same amount of time rather the next instruction to be executed after an instruction can not start until the next clock cycle ,current instruction may complete before the current cycle because cycle length is determined by the longest instruction.e.g add register completes before load in a RISC.Now in a pipelined structure processor ismultistage with register to store and propogate the state of processor.Now basically on pipelined processor we save time by overlapping two instructionss' substages.hence even though individually the length of instruction is increased but overall time has reduced.Now see every instruction may not go through all the stages eg load and add again
So overall latency for each instruction will consist of all the stages but its execution may have had taken less number of cyclesSo you can say that latency of each instruction is same but not the execution time or cycles consumed
|
I understand that single-cycle programs are not very efficient. One reason is because not all instructions are equal in length, but in a single-cycle program, all instructions are completed in the same length of time.In pipeline, throughput is increased, which means the time between one output and the next will be shorter than in a single-cycle implementation after you reach a certain point. But then can you say that instructions in a pipelined approach take the same amount of time (going from IF/Instruction Fetch to WB/Writeback)? Or is this the wrong conclusion?

Single-cycle vs a pipelined approach

You'll need to create your own function for that if you want to do it in the pipeline:function format-conditional
{
param ([bool]$condition)
if ($condition) {$input | format-wide }
else {$input}
}
$test = $true
gci | format-conditional $test
|
I want to conditionally applyFormat-Wideto a pipeline:Get-ChildItem | Format-WideHow can I make| Format-Widepart conditional on a variable? For example, apply| Format-Wideonly if$conditionisTrue.Edited: the following is what I want to achieve:function format-conditional {
param ([bool]$condition)
if ($condition) {$input | Format-Wide -Column 3 }
else {$input}
}
Invoke-Expression ("Get-ChildItem $Args") |
%{
$fore = $Host.UI.RawUI.ForegroundColor
$Host.UI.RawUI.ForegroundColor = 'Green'
echo $_
$Host.UI.RawUI.ForegroundColor = $fore
} | format-conditional $falseBut with this theGreencolor is gone.

I need to process a file that contains some lines beginning with a dash (-); these are continuation lines that need to be appended to the previous line. so what I have is something like:Lorem ipsum dolor sit amet, consectetur
- adipiscing elit. Donec
- consectetur lotis.
Sed a est dui.
Curabitur placerat a tortor
- vel sodales.and what I want is:Lorem ipsum dolor sit amet, consectetur - adipiscing elit. Donec - consectetur lotis.
Sed a est dui.
Curabitur placerat a tortor - vel sodales.so I've written something like this:$s = ""
cat $f |%{
if ($_ -match "^-") { $s += $_ } else { $s; $s = $_; }
} |out-file x.txtMy question is: in cases when the file ends with dashed lines, the script never outputs the final line, because upon receipt of the final line from the pipe, it doesn't know it's the final line.In Perl I used to be able to use a construct like END {} to do these things. How would that be handled in Powershell?UpdatePerl is relevant because in that language I could do something like (wheretxtis a file containing the relevant text):perl -lne '
BEGIN { $s = "" };
if (/^-/) { $s .= $_ } else { print $s; $s = $_; }
END { print $s; }
' txtwhere, as you can see, the END{} construct solves my problem

You should be able to specify the retry semantics on the send adapter which makes the call to the web service.
|
I have a custom receive pipeline in BizTalk 2009 which after receiving the message from a file location connects to a web service to fetch some data. Sometimes there is some issue with the web service and Biztalk is not able to connect to the same and hence the message gets suspended. If we resume the message after say 1-2 minutes the message is processed. So I want to implement a retry mechanism in the receive pipeline only so that there is no manual effort required. can this be done somehow?

pipeline.InOrder()andpipeline.After()are only for ordering pipelines execution, not code execution.There is a method calledfinalized, that is executed right after the last output is written, that is when yourLog2Bq()pipeline finish it's execution, so:class Log2Stat(base_handler.PipelineBase):
def run(self, _date):
print "start track"
yield pipelines.Log2Bq()
def finalized(self):
print "finish track"
taskqueue.add(
url='/worker/update_daily_stat',
params={
"date": str(_date.date())
}
)If you want to use pipeline.InOrder() or pipeline.After() you should wrap your taskqueue code in other pipeline and yield it afterpipelines.Log2Bq()with pipeline.InOrder():
yield pipelines.Log2Bq()
yield pipelines.YourOtherPipeline()
|
https://code.google.com/p/appengine-pipeline/wiki/GettingStarted#Execution_orderingI tried to add a callback function which execute after the Log2Bq done.
But it doesn't work either I usepipeline.Afterorpipeline.InOrder. In the following code sample, the taskqueue will execute immediate without waiting for Log2Bq. To fix the issue,
do I need to create another pipeline to hold the taskqueue in order to make the execute order works?class Log2Stat(base_handler.PipelineBase):
def run(self, _date):
print "start track"
with pipeline.InOrder():
yield pipelines.Log2Bq()
print "finish track"

You should be able to do this withsqoopby using the option called--staging-table. What this does is basically act as an auxiliary table that is used to stage exported data. The staged data is finally moved to the destination table in a single transaction. So by doing this, you shouldn't have consistency issues with partial data.(source:Sqoop documentation)

Background :I have a Hive Table "log" which contains log information. This table is loaded with new log data every hour. I want to do some quick analytics on logs for past 2 days, so i want to extract last 48 hours of data into my relational database.To solve the above problem I have created a staging hive table which is loaded by a HIVE SQL query. After loading the new data into the staging table, i load the new logs into relational database using sqoop Query.Problem is that sqoop is loading data into relational database in BATCH. So at any particular time i have only partial logs for a particular hour.This is leading to erroneous analytics output.Questions:1). How to make this Sqoop data load transactional, i.e either all records are exported or none are exported.2). What is best way to build this data pipeline where this whole process of Hive Table -> Staging Table -> Relational Table.Technical Details:Hadoop version 1.0.4Hive- 0.9.0Sqoop - 1.4.2

you can use decodebin2 or uridecodebin element. These elements contain autodetct capabilities.http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-uridecodebin.html
|
Using gst-launch is there any way to select a GStreamer Element based on the capabilities determined by a source element? For example, if I have a network source element which could download an MP3, M4A, or WAV file, can I select which element to pipe the data to based on the file type received? The file type is not actually known until after the network source element is loaded. See the linked image below for the pipeline I have in mind. Any ideas?

HTTP PipeliningWikipediaandMozillahave good pipelining explanations. The following picture basically says it all.Normally (without pipelining), the client sends a request to the server and waits for a response before sending another request. With pipelining, however, the client sends multiple requests without waiting for the server's response.So, what does my server have to do to implement pipelining?Actually, not much. All a server has to do to support pipelining is ensure that "that network buffers are not discarded between requests" (wikipedia). All HTTP/1.1 servers support pipelining.The client is responsiblefor the bulk of the error handling (resending packets, etc.) and other headaches that come with implementing pipelining.
|
Can some one explain me how pipelined requests are treated on a server in python (or any other scripting language)?Suppose I have web services made in python callable by iOS client. The client pipelines the requests and sends them to server. How can I receive and handle these requests on the server and send the appropriate response?

$thirdParamcannot be an array with your implementation. When you write$thirdParam = @(), you do declare an empty array, but then you re-assign it to a string:$thirdParam = 'test3'and then to another string$thirdParam = $thirdParam + 'test4'. I am still not clear about your original intent, but here's how you would passtest3as third argument andtest4as the fourth:$fourthParam = 'test4'
[void](& '..\SomeApp.exe' "$firstParam" "$secondParam" "$thirdParam" "$fourthParam"If you only have 2 fixed parameters, and you can have N parameters, switch toInvoke-Expressioninstead ofInvoke-Command:[void](Invoke-Expression "..\SomeApp.exe $firstParam $secondParam $thirdParam"and make sure your parameters are correctly quoted. In this case, if $thirdParam contains spaces, it will determine your parameter #4 and onwards.

Wondering how I could pass an array as command line argument to an exe file in powershell? Here is what I am currently working onI am calling an exe file from a powershell function in the following format$firstParam = "test1"
$secondParam = "test2"
$thirdParam = @()
$thirdParam = 'test3'
$thirdParam = $thirdParam + 'test4'
[void](& '..\SomeApp.exe' "$firstParam" "$secondParam" "$thirdParam"Here is what I am seeing as the input arguments in the Application.exeThe third input parameter that was passed from the powershell was an array but it got concatenated (space separated) when passed to the exe file.Is it possible to pass "test3" as the third argument and "test4" as the fourth argument?

I think you are trying to run before you can walk. That said, let's take a look at your first example above:function my-function {
process {
$_ | select-string "hello"
}
}
"hello" | my-functionNow, you may be saying to yourself: "Hey, that's not what I asked!" and to this, I offer the following advice on Invoke-Expression (iex): Executing arbitrary text like this can be dangerous, and is rarely required. It generally indicates a lack of understanding of building interoperable functions and modules. Even throwaway scripts rarely require IEX.So, I'm not just going to leave it there but I can't reasonably answer your question without a higher level point of view on what you're trying to do. It sounds like you're trying to generalize some process for executing script, or scripts. So, my advice would be to study the various native mechanisms for doing this in PowerShell, namely the dot source (.) and call (&) operators.And finally, grab a coffee and sit back to read through Keith Hill's most excellent "Effective Windows PowerShell" free ebook:http://rkeithhill.wordpress.com/2009/03/08/effective-windows-powershell-the-free-ebook/The first few chapters will help you tohelp yourselfwhen learning the right way to do things. It covers the primary tools of PowerShell: get-command, get-help, get-member and understanding the difference betweencommandandexpressionmodes.

I can't get my function to work using iex (invoke-expression) with variables. What I want:function My-Function {
# code that constructs $command
#$command is an arbitrary string that may contain pipes,
#variables, command line paramaters, switchs, quoted strings, THE LOT!
Execute-My-Command-Exactly-As-Though-I-Had-Typed-It-Here $command
}For examplefunction My-Function {
$command = "`$input | select-string hello"
iex $command
}Does this (after . including my file which contains the above function)PS C:\> echo "hello" | My-Function
PS C:\>But obviously it should do this:PS C:\> echo "hello" | My-Function
hello
PS C:\>Moreover on the actual command line, variables DO seem to be picked up by iex:PS C:\> $hello = "hello"
PS C:\>
PS C:\> iex "`$hello | select-string hello"
hello
PS C:\>The only workaround I can think of is to actually write out a function to a file, then . include it, then call it. But this is awful! The whole point of a good shell-scripting language is it should be able to do this meta stuff easy peasy.SOLUTION:PowerShell can't do it, though latkin provides a helpful tip.

How do you execute an arbitrary string inside a powershell script/function as though the string had actually been typed into the script/function?

Where you defined your pipeline is fine.args.Context.Requestshould be available at this step in the request processing. The most likely cause is that this processor is being evoked under certain circumstances where the Context is not available. A simple check for the following should handle those cases:if (args.Context != null)
{
//....
}The only other explanation I can think of is thatGetState()orRedirectUserByState()are callingHttpContext.Currentwhich is not available at this point (hence why Sitecore passes the context as an argument).Also, a load-balancer would not explain the exceptions, but you may have better luck checking for the following server variables if the IP ends up always be the same:args.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]
args.Request.ServerVariables["REMOTE_ADDR"]

I am trying to do this with an httpRequestBegin pipeline processor, but I don't seem to be able to access the user's IP address from the given HttpRequestArgs parameter.When I implement a class that has this methodpublic void Process(HttpRequestArgs args) {
string ipAddress = args.Context.Request.UserHostAddress; // Not working
string state = GetState(ipAddress); // already implemented elsewhere
RedirectUserByState(state); // already implemented elsewhere
}I thought that this might hold the user's IP addressargs.Context.Request.UserHostAddressbut it causes this error instead (stack trace says it originates from the Process method):System.Web.HttpException: Request is not available in this contextAny ideas? Thanks!Edit, this is in Sitecore 6.1 and in the web.config at<pipelines>
<!--...-->
<httpRequestBegin>
<!--...-->
<processor type="Sitecore.Pipelines.HttpRequest.ItemResolver, Sitecore.Kernel"/>
<processor type="MySolution.Redirector, MySolution"/>
<processor type="Sitecore.Pipelines.HttpRequest.LayoutResolver, Sitecore.Kernel"/>
<!--...-->
</httpRequestBegin>
<!--...-->
</pipelines>This server might be behind a load balancer.Edit 2:It looks like Iwastrying to access both of these inside the Process() function and that is what was causing the error:Sitecore.Context.Request
Sitecore.Context.Response

Double click the green arrow. You will have the following dialog:Choose the "Logical OR" like in the above image. This will make your green lines become dotted. Now you can connect several arrows to the same task.The way you had the task worked like anAND, meaning that the task would only execute if BOTH the constraints were successful.
|
I want to execute the same task in two different conditions. They are
1. If the job is successful and RowCount is 0.
2. If the job is successful and it has executed other tasks.I tried to use the same SQL Execute Task but regardless of the outcome, it does not execute that task. Please see the screenshot below.But I replicated that job and connected directly to the other job. At that time, it works. Does it mean that we can't have different route to execute the same task?Thanks.

I suggest that you import the Python module with your button before calling the function. Assuming your script is in maya/scripts/tep.py, your button would do the following:import tep
tep.psource()If you wanted to modify the script and keep running the fresh version every time you hit the button, do this:import tep
reload(tep)
tep.psource()And if you want your module to load on Maya startup, create a file called userSetup.py in your maya/scripts directory and have it do this:import tepThen, your button can simply just:tep.psource()Or...reload(tep)
tep.psource()

The server side request queue is provided by application container and not by servlet itself.In case of Tomcat the component responsible for that is called Connector which can be configured (server.xml) in terms of the number of threads that serve incoming requests, timeout that request can stay unprocessed in the queue, the size of the queue, etc.Have a look atTomcat Connector documentation, I believe the most important would be 'acceptCount', 'maxThreads', 'connectionTimeout', 'maxKeepAliveRequests' (if you require http keepAlive ).

You can use the HttpContext (the one exposed by the static Current property). It has an Items property which is meant to be used specifically to shuttle data between modules and handlers, as indicated by the documentation:Gets a key/value collection that can
be used to organize and share data
between an IHttpModule interface and
an IHttpHandler interface during an
HTTP request.Which can be located here:http://msdn.microsoft.com/en-us/library/system.web.httpcontext.items.aspx

From an HTTP module, is there a way to persist something in the Request to be accessed by a mater module or the eventual handler? Can you "stick" something on the Request as it passes through that will still be there later in the pipeline?

First, you must ensure thatnpm installworks on your local machine. Often the problem comes from the fact that you use^to specify the version of your dependency, see more details about semantic versioninghere. In this case, you do not have much control over the exact version of dependency and their dependencies, and sometimes, the project breaks. I would recommend removing^to control exact versions manually, and runningnpm outdatedfrom time to time, to see if you want to proceed with updates. Silent automatic updates may give you surprises, such as it worked yesterday, but stopped working today "for no reason".Then, you should ensure that your deployment uses the same versions of all the dependencies. This is why the filepackage-lock.jsonexists. Seeherefor more explanation. I recommend committing this file to your repository and runningnpm cito install the dependencies, seehere.A similar approach should be applied toyarnpackage manager or others.

While it is straightforward to update a FCT table from given large table (you have to select fact columns from big table and insert them into FCT table), updating a DIM table from a given big table poses one major problem - slowly changing dimensions.In the big table - It is theoretically possible to have different car names (or any car detail) for the same car ID. In such a case your dim table would also have to track history of changes to a particular car ID. This is so that you can correctly join the FCT and DIM tables to get back your original table.To overcome this you will have to add thedate_transactionfield from your big table to the DIM table, effectively creating a composite key (id, date_transaction) on the DIM table.Your flow would look likeNote - Filtering out new DIM rows that have changed can be an expensive process. However, not doing so will mean your DIM table has as many rows as your FCT table (which kind of beats the purpose of decomposing).

I have very large table that contains repeated dimensions as strings and it has more than 40 million rows. This table is populated with millions of records every day.The facts and dimensions table would reflect the information inside the very large table. The facts and dimensions are updated with the new information inserted in the big table and the operation should be fast (considering millions of new rows are inserted in the big table every day)Here's an example:Here's is the pipeline I assume is the most efficient and fastIs there any way to do this pipeline efficently in SQL Server? Is there another method that would be faster?

If multiple pipelines are triggered simultaneously, it is not possible to order the runs of stages like as you require.for your case, as a workaround, you can consider the method like as below:Within each pipeline, you can use the 'dependsOn' key to order the runs of stages.# Stage 2 will run after stage 1 complete.
# By default, stage 1 should complete successfully.
stages:
- stage: 1
. . .
- stage: 2
dependsOn: 1
. . .To order the runs of pipelines, you can use pipeline resource trigger (Pipeline completion triggers).In pipeline for App2, set the configuration like as below.trigger: none # Disable CI trigger.
resources:
pipelines:
- pipeline: App1
source: App1 # Actual name of the pipeline for App1.
trigger: trueSimilar, in pipeline for App3, set the configuration like as below.trigger: none # Disable CI trigger.
resources:
pipelines:
- pipeline: App2
source: App2 # Actual name of the pipeline for App2.
trigger: trueWith above configurations, the stages will run following the order like as you expect.

I have microserviced monorepo in Azure Devops, with pipeline for each of the nested services.root
/app1/app1-pipeline.yml
/app2/app2-pipeline.yml
/app3/app3-pipeline.ymlEach of the pipelines has 2 stages:For building and pushing docker imagesCheckout to another repository, running py script and git pushing output (with metadata).When for example 3 of the pipelines are triggered by the same commit , I can see that the order of execution of stages is the following:App1 - stage 1App2 - stage 1App3 - stage 1App1 - stage 2App2 - stage 2App3 - stage 2I am looking for a way to "force" the order of execution to the following:App1 - stage 1App1 - stage 2App2 - stage 1App2 - stage 2App3 - stage 1App3 - stage 2In other words I want the runner to sequentially execute the pipelines one by one, instead of mixing them.I couldn't find a solution for it.Is this possible or maybe it is not recommended(why)?Thank you in advance!

Yes, that is possible. For writing in BigQuery without using a window, you will need tousemethodequal STREAMING_INSERTS or STORAGE_WRITE_API (maybe withuse_at_least_onceset toTruefor even lower latency, but with risk of duplicates).For the rest of the pipeline, you just need to have two branches. Something like this:msgs = p | "Read from P/S" >> beam.io.ReadFromPubsub(...)
dictionaries = msgs | "Transform to dict with some schema" >> ...
dictionaries | beam.io.gcp.bigquery.WriteToBigQuery(...,method=STORAGE_WRITE_API, use_at_least_once=True,...)
dictionaries | beam.WindowInto(FixedWindows(size=300)) | ... # (aggregate, write to another BigQuery table, etc)

I am trying to think of how to architect some data pipeline needs, and I simply want to know if the following is possible:Can I create an Apache Beam pipeline that can stream data fully real time while also aggregating into windows? Specifically, I would like to:Read data in from a Pub/Sub subscription.Send that data onward immediately to a BigQuery table, as is.Create an Apache Beam window of, say, 5 minutes.Aggregate that same data read in from the Pub/Sub message (with some other light transformations).Write the aggregated/transformed data into a different BigQuery table.As an always-on streaming pipeline process.I know that I can do this in other ways. For instance, I can create 2 dataflow jobs / pipelines that listen to the same subscription. (Or would it be better to have 2 separate subscriptions listening to the same topic?) I can also create a subscription for the dataflow job, then another subscription (to the same topic) that just pushes to BigQuery immediately.But if I could have one set of code -- and therefore one CI/CD job to monitor -- to accomplish both, it simplifies what we need to maintain, and it would be much preferred.Is this possible?

When your pipeline completes, you call stop and then you delete the pipeline. When you delete the pipeline it will destroy all of the underlying resources that was created to execute it.execution.stop()pipeline.delete()https://docs.aws.amazon.com/sagemaker/latest/dg/run-pipeline.html#run-pipeline-delete

Pandas and PySpark are very different. Although PySpark provides inter-operability with Pandas, a pandas DataFrame is very different from PySpark/Spark DataFrame.Understand the differences between Pandas and PySpark before you write any code.There are two parts to your problem. First is understand how to read/write to/from csv and parquet files, which reside on your laptop's hard disk. Second is how to use ADSL instead of local hard disk.For first part:See the examples that come withPySpark docs. E.g.how to read from csv into a DataFramehow to write a DataFrame to parquet.Also see the PySpark SQL API docs (PySpark SQL API is a python API, not SQL). E.g.read/write csvread/write parquetFor second part:When working with a cloud storage as underlying storage (ADLS, S3, ...), you need to:Prefix all your paths with appropriate scheme e.g.s3a,abfss, ...Install appropriate hadoop extension/library (that corresponds-to/supports the scheme) in your pyspark env. PySpark will use this to read/write to cloud storage.Set appropriate config params in Spark config or whatever way you use to authenticate.There are many guides available depending on your usecase,here is one, andhere is another.

I'm just stepping into the data world and have been asked to create a custom project where I need to convert a CSV to a parquet using a Notebook (PySpark).

# Write PyArrow Table to Parquet file
pq.write_table(table, output_file_path)
# Open the Parquet file

# Convert the table to a Pandas DataFrame
df = table.to_pandas()
# Print the DataFrame

Dataflow activity won't give the input query in its input or output. As a workaround try the below method.Take a branch to your dataflow and usederived columntransformation. In this create a column andgive the same query expressionto this.You can add this by taking a branch to your current source or you can create another sample source and continue the same approach.Here, I have taken SQL query for sample.It will build the query and stores the query string in the columnquery. Usecache sinkto know this query at pipeline level. The write order for this sink should be 1.In the cache sink mapping, filter thequerycolumn using Rule based mapping like below.In the Dataflow activity, set the logging to None and select first row only.Now, you can find the input query in the Dataflow output cache sink.Use the below expression to use this in the pipeline.@activity('Data flow1').output.runStatus.output.sinkCache.value[0].query

If you need a highly secure solution, then you should use a dedicated secrets management service such as Google Cloud KMS or HashiCorp Vault.

Each pipe is essentially a class that handles a piece of logic. The class should define an handle method:namespace App\Pipes;
class SomeServiceIntegration
{
public function handle($user, \Closure $next)
{
// ur codes
return $next($user);
}
}You can use the Pipeline class to send an object through the defined pipes:use Illuminate\Pipeline\Pipeline;
$integrations = $user->integrations;
if ($integrations->count()) {
// at here., you need to get the classes (pipes) for each integration
$pipes = $integrations->map(function ($integration) {
return $integration->serviceClass; // i assume that you store the full class path in the 'serviceClass' attribute
})->toArray();
return app(Pipeline::class)
->send($user)
->through($pipes)
->thenReturn();
}If each service has its own settings, you may need to add settings:$pipes = $integrations->map(function ($integration) {
return app($integration->serviceClass, ['settings' => $integration->settings]);
})->toArray();And adjust the SomeServiceIntegration class to accept settings:namespace App\Pipes;
class SomeServiceIntegration
{
protected $settings;
public function __construct($settings)
{
$this->settings = $settings;
}
public function handle($user, \Closure $next)
{
// u can use $this->settings here easily :○
return $next($user);
}
}

I have aUsermodel, several external services are attached to it (Servicesmodel, multiple communication),
I don’t know in advance how many external integrations there will be, what settings they have (each service is implemented as a separate class, and the integration settings are described in the properties of theServicesmodel).I want to use the Pipeline template. But I can't find any good Laravel code examples and documentation.It should look something like$integrations = $user->integrations;
if ($integrations->count()) {
return app(Pipeline::class)
-> send($user)
-> through($integrations)
-> thenReturn();
}But i cannot understand how it works inside... how to implement Pipes classes?

I've had this issue with both Git and TFVC on DevOps. I've established a pipeline that copies the git (or tfvc) directory to what is our test server, which is a local/physical windows server with iis running a coldfusion instance. The server is in the agent pool and the files are updating with WindowsFileCopy. The problem is that, even if I only change one file, it does this step "checkout test@main to s" which copies the whole directory to a folder in the C: drive (C:\agent_work\1\s), then from there it copies the whole directory to the target one ( c:\inetpub\wwwroot\intranet ).

By default, Taipy runs in development mode, which deletes data and scenarios upon each execution.To retain scenarios, you can use either the 'experiment' or 'production' modes (see thedocumentation).To run in 'experiment' mode and create/run version V1:python main.py --experiment V1This ensures that your scenarios and data remain intact.To run your application with VS Code:Set up alaunch.jsonfile (you can create it under the debug tab in VS Code).Add the following to the file (.vscode/launch.json):"args":["--experiment", "V1"],

I created a Taipy application to create scenarios with predictions and metrics, but when I rerun my code after stopping it, I lose all my scenarios and data. Where does it come from? How can I keep my scenarios and data?

When splitting the declaration of infrastructure over different configurations that are independently applyable, it's important to choose the division points carefully so that the different configurations reallyareindependently applyable. Terraform only works with one configuration at a time, so it cannot automatically resolve changes that would require simultaneous changes in two different configurations.This is not inherently a problem withterraform_remote_state-- the same problem could arise with any use ofdatablocks to depend on objects managed elsewhere. The root problem here seems to be that Y is declared to manage something that should perhaps actually be managed by X, because it needs to immediately change in response to other changes in X.Exactly how to resolve that will depend on exactly which infrastructure objects you're using in practice. Reorganizing which objects are managed by which configuration might solve the problem, but it also might introduce another similar problem. Sometimes successfully splitting infrastructure into two independent units requires a different design approach where e.g. there's some third unit that both X and Y depend on, which provides some way for X and Y to successfully collaborate.If you ask a new question where you name exactly the resource types you are using and share your configuration then you may get a more actionable answer.
|
I have two Terraform modules -XandY- whereYdepends onXthroughterraform_remote_statedata source.Xis deployed beforeYin the pipeline, which means that the pipeline fails wheneverXhas changes that cause resources to be re-created and/or deleted. In this case, the resource inXcannot be deleted as it's used by some resource inY.How is this problem normally solved? Is it an anti-pattern to useterraform_remote_statein the first place?
|
Terraform cannot re-create/delete resources in a module, because they're used by dependent modules through terraform_remote_state?

You can add a new schedule with a variable and change gitlab-ci.yml . For example:job:
script: echo "Hello, Rules!"
rules:
- if: $CI_PIPELINE_SOURCE == "merge_request_event"
when: manual
allow_failure: true
- if: $CI_PIPELINE_SOURCE == "schedule" && $SCHEDULE_TIMING == "hourly"and add new schedule with variable

I have several jobs that are set to be triggered only for scheduled tasks. Some job requires to run every hour and other is set to run every day.How do I set the job to run on schedule and also on specific schedule tasks/definitions? I know GitLab CI has an option to set rules for jobs to run on schedule but I could find an option to set a specific schedule given that I have many scheduled tasks.For example:job:
script: echo "Hello, Rules!"
rules:
- if: $CI_PIPELINE_SOURCE == "merge_request_event"
when: manual
allow_failure: true
- if: $CI_PIPELINE_SOURCE == "schedule"The rule- if: $CI_PIPELINE_SOURCE == "schedule"is very generic. I don't want some job to run every hour. I want it to pick the schedule that is set to run every day only for example

When I am creating the pipeline and use for example the "Deploy Azure App Service" template the task option for "Azure Subscription" is disabled and I can't select my already configured connection.I know everything is ok because I already tested the connection using a build yaml pipeline with the task "AzureRMWebAppDeployment@4" and the deploy process using the connection was successful.Is there a way the option become available so I can use it in a release pipeline?

Similar to 'sp_start_job', is there a way to execute a Data Factory Pipeline from SQL Server via a stored procedure?I tried researching and everything seemed to come back to using stored procedures within Azure Data Factory. I'm familiar with that, but I want to execute it from the SQL Server environment.It might not be possible. Another option could be to use a trigger based on data within SQL Server, but I'd rather not go that route.

If your code was as follows:command_assembly = f'{a} {b} {c}'
result = subprocess.run([self.APP_ASSEMBLY, command_assembly], capture_output=True, text=True)`You would be callingself.APP_ASSEMBLYwith only one argument, which would be the values ofa,bandcseparated by spaces.This is different from what you almost certainly want, 3 arguments, which would be accomplished like this:command_assembly = [f'{a}', f'{b}', f'{c}']
result = subprocess.run([self.APP_ASSEMBLY, ...command_assembly], capture_output=True, text=True)`The code you provided, once corrected, would then look like this:command_assembly = [f'{self.INPUT_ASSEMBLY_SRC}{self.file}',
f'{self.ASSEMBLER}', f'{self.ONLY_ASSEMBLY}', f'{self.MIN_PARAMS}',
f'{self.CUT_OFF}', f'{cutoff}',
'-o', 'out']
result = subprocess.run([self.APP_ASSEMBLY, *command_assembly], capture_output=True, text=True)`Further explanation can be foundhere.

what's wrong with the code below:command_assembly = f'{self.INPUT_ASSEMBLY_SRC}{self.file} ' \
f'{self.ASSEMBLER} {self.ONLY_ASSEMBLY} {self.MIN_PARAMS} ' \
f'{self.CUT_OFF} {cutoff} '\
f'-o out'
result = subprocess.run([self.APP_ASSEMBLY, command_assembly], capture_output=True, text=True)`In my tests, the run method seems to only capture one parameter and not the entire string that contains multiple parameters. Remembering that running in the terminal everything works perfectly with the string above.

In summary, you need to abort the build without failing.How to abort?However, you are only testing thewhencondition into one single stage, this is why the stage is skipped but the build continuous.As per design, thewhenexpression for Jenkins DSL cannot be executed outside a stage.DocumentationSo you have two alternatives:Duplicate the samewhencondition in each stage.Easy but inefficient.Configure an upstream job to only very if the condition is met (changes found), if so, then call the other downstream (existing) pipelines.Complex but efficient.

I have a C# repo that has multiple Projects inside of a single solution. Each Project has their ownJenkinsfilebut they could share a Pipeline with another Project. Inside of theirJenkinsfileit gives a subdirectory. I am trying to get it to where it will only continue through the Pipeline if there have been changes to a subdirectory.stage ('Check Subdirectory for Change') {
when {
allOf {
expression {
config.Project.SubDirectory != ""
}
not { changeset config.Project.SubDirectory + '/**' }
}
}
steps {
script {
currentBuild.result = 'SUCCESS'
config.ContinueBuild = false
}
}
}This is my current setup inside the pipeline. This will do the check and then skip the stage if there weren't any changes. The problem is that if there are no changes it will skip theCheck Subdirectory for Changestage and continue the build. I need it to exit the build inside and ONLY continue if there was changes to the subdirectory.

Use the below query in the pre-copy script to achieve your requirement.IF EXISTS (SELECT 1 FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = '@{pipeline().parameters.tablename}')
begin
TRUNCATE table [@{pipeline().parameters.schema}].[@{pipeline().parameters.tablename}];
endAnd make sure you select theAuto create tablein the copy activity sink.Here, our pre-copy script checks whether the table exists or not, if exists it truncates the table. If not exists, it won't do anything.TheAuto create tablecreates new table only when the table is not exists in the schema, if it already exists it won't do anything.Here, my table already exists with one row, so it truncated the table and inserted values from the source.

php:7.0is pretty ancient, it was end-of-lifed more than 4 years ago. It's built on Debian 9 "Stretch" which was end-of-lifed last year. The apt repositories are no longer maintained, so yourapt updateis not updating anything and yourapt installis not installing anything. You might be able to find an old pre-built Docker image that already has the needed packages installed, but you'll need to face the inevitable march regardless.If you want to keep running PHP 7.0, you'll probably have to build your own image, starting from something recent like Ubuntu 22.04 LTS and then compiling PHP 7.0 from source. It's certainly doable but would not be my recommendation. It would likely be less effort to just update your pipeline (and your app) to use PHP 7.4. Note that this is also already past end-of-life, but you'll still be able to get running images of it for a while.Sooner or later, you're going to have to update your app to PHP 8. If you're having problems doing that,Rectorcan be very helpful.

Yes, you can change the build description in Jenkins when triggered by a GitLab webhook.
To do this, you need to add some additional parameters to your Jenkins pipeline script that will allow you to specify the custom build description.pipeline {
agent any
stages {
stage('Build') {
steps {
sh 'echo "Build started"'
}
}
}
post {
always {
// Set custom build description based on git commit message
def customDescription = sh (script: 'git log -1 --pretty=%B', returnStdout: true).trim()
// Use the custom description if available, otherwise use default message
currentBuild.description = customDescription ?: "Started by GitLab push by ${env.GITLAB_USER_LOGIN}"
}
}
}

i`m trying to connect jenkins with gitlab by WebHook.
when i push specific branch, webhook call jenkins pipeline.
and each build has a description and that prints "Started by GitLab push by XXX".now i have a question, can i change that word by myself?
i want to change that to what i want. for example, git commit message or something in Merge Request.please, let me know!
sincerely.I tried to search on stackoverflow and google, but I didn`t get the proper way to control it. So I leave a note here .

how to change jenkins build description "Started by GitLab push by " statement when using gitlab
|
Yes I think it’s possible.I think if you change your deploy stage to check for another gitlab variable (one that you set dynamically or within a schedule) like: … TARGET_BRANCH_NAME == "master" && $CI_PIPELINE_SOURCE == "merge_request_event" && $DEPLOY == “true”Then that job should only occur when a $DEPLOY variable has been set to “true” which won’t happen when you simply merge to main, unless you set it.Then you can trigger a new pipeline run manually and add the variable and it will deploy.

After some research I found out that these variable are not gobal. Can some one help me how put these value as gobal or let me know if I am doing something wrong.

There's no native solution for this. However, I've approximated something like this usingpre-commithooks.Basically, there is apre-commithook script that will generate the possible choices and edit thevariables:key in the.gitlab-ci.ymlto contain all the appropriate options whenever they change. I also setuppre-commit autofixingin the GitLab pipeline so you never have stale options.

- find -type f | grep microservicesThank you!

I'm reading through the mongodb pipeline documentation athttps://www.mongodb.com/docs/compass/current/aggregation-pipeline-builder. Based on this in mongodb compass gui , I can create , name and save a pipeline. However to get the data I want, I would ideally like to run 2 separate queries from the original collection, then merge the results producing a 'Y' shaped pipeline. you can do something like:db.collection.aggregate([
{
"$match": {
"PENALTIES": {
$ne: "$0.00"
}
}
},
{
"$unionWith": {
"coll": "collection",
"pipeline": [
{
$match: {
$and: [
{

{

$ne: "$0.00"
}
}
]
}
}
]
}
},
{
"$merge": {
"into": "new-collection"

Availability ofsourcedepends on the actual shell jenkins uses. As mentioned in the comments, you probably should use.instead ofsource.However; activation and deactivation of venv is related to the scope ofsh.If you have multiple steps and multiplesh's you need to activate the venv for each of those where you need to access python libs/tools installed into venv. This is because activation is applied the current shell and if you activate it on onesh, once that stops, venv settings are automatically deactivated because nextshwill spawn a new shell.

We are running integration tests, written in Python, in Azure Pipeline. These tests access a database, and the credentials for accessing the database are stored in a variable group in Azure, including secret variables. This is the part of the yaml file, where the integration tests are started:jobs:
- job: IntegrationTests
variables:
- group: <some_variable_group>
- script: |
pdm run pytest \
--variables "$VARIABLE_FILE" \
--test-run-title="$TEST_TITLE" \
--napoleon-docstrings \
--doctest-modules \
--color=yes \
--junitxml=junit/test-results.xml \
integration
env:
DB_USER: $(SMDB_USER)
DB_PASSWORD: $(SMDB_PASSWORD)
DB_HOST: $(SMDB_HOST)
DB_DATABASE: $(SMDB_DATABASE)The problem is, that we cannot read the value of SMDB_PASSWORD, as it is a secret variable. In order to use the secret variables, it is advised to use arguments in a PythonScript task (like here:Passing arguments to python script in Azure Devops)
but i am not aware how to modify this script to be defines PythonScript, as it includes using pdm.

The issue is with the format of the variables section in the .gitlab-ci.yml file. According to the error message, the configuration of variables should be in key-value format, but the given value is in an incorrect format.To resolve the issue, try changing the format of the ver variable to a key-value pair, like so:variables:
ver: "13"not:
variables:
ver:
value: "13"

I have errors when pushing it to the repo. Error says:Found errors in your .gitlab-ci.yml:

You can build a delay step into your pipelines yaml file between the setup of your docker image and your test execution.# Delay v1

I am using Maria DB docker image for integration tests. I start it in an Azure pipeline via the following commands:docker pull <some_azure_repository>/databasedump:<tag_number>
docker run -d --publish 3306:3306 <some_azure_repository>/databasedump:<tag_number>And after that integration tests, written in Python, are started.
But when the code tries to connect to the Maria DB database, mysql error is returned.+ 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 0Maybe the reason for that is, that the Maria DB database is big and it needs some seconds to be started.
So my question is whether there is a way to set a sleep of several second in a pipeline execution? In a script or bash section.

You can put the python script file inAzure Git Repositoryand use the repository as the pipeline source. Then addRun a Python scripttaskin pipeline and specify the script path like below.Torun Python scriptsin your repository, you can also use a script element and specify a filename in YAML pipeline. For example:- script: python src/example.py

I am new to DevOps and this whole world, so I would like some help.I have an existing pipeline created. I also have a python script that I have just created, this script gets a json file, replace some stuff and replace the file content (I tested with a local file). Now I need to add this python code to my pipeline tasks, this task should copy a repository file, and process it.I Googled trying to find a way of achiving this, but nothing. I do not even know where to place the python script.Would anyone be able to point me to some direction?Thank you very much.

Refer to this doc：Enable upstream sources in an existing feedCustom public upstream sources are only supported with npm registries.The cause of the issue is that custom public upstream sources are only supported with NPM registries. This is the limitation of Azure Artifacts.For a workaround, to use multiple private nuget sources, you can define the nuget resource in Nuget.config file and create nuget Service connection inProject Settings -> Service connections.Then you can use the service connections in nuget restore task.For example:Update:Nuget Restore task sample:- task: NuGetCommand@2
displayName: 'NuGet restore'
inputs:
feedsToUse: config
nugetConfigPath: $(build.sourcesdirectory)/targetfolder/nuget.config
externalFeedCredentials: 'nuget1027, test nuget feed'
|
In Azure pipelines, the Nuget Restore task allows me to specify a feed in my organization. However, that feed can apparently only have one upstream source per type (nuget, npm, etc.), and that upstream source is nuget.org.
I have another nuget feed that I need to pull in as well, but since we're only allowed to have one upstream nuget source for our custom feeds, I'm not quite sure how best to tackle this.edit: Actually, even after removing nuget.org as the upstream branch, I still can't add another upstream branch aside from NPM.. I thought it was unable to be selected because I already had Nuget.org included.

I want to trigger a Test pipeline from a stage of Main pipeline, both the pipelines are present in different projects within the same organization. I am able to trigger the pipeline using the resource option but the problem is it triggers the Test pipeline when Main pipeline finishes successfully but I want to trigger the Test pipeline in between run of Main pipeline using an stage. Is it possible to achieve this using any feature of Azure Devops?For now I am adding this resource in Test pipeline yaml to trigger after Main pipeline.resources:

You can always deploy previous versions of your application in different release or buildYou should have a quality ansurance environment before production environment so as to check if new changes will workIf you want to combine rollback deployment inside the same build you can use stage conditions to add new stage which will run only if previous stages failCheck failed() condition and combine it with 'and', 'or' keywordshttps://learn.microsoft.com/en-us/azure/devops/pipelines/process/stages?view=azure-devops&tabs=yaml#conditions# stage B runs if A fails

This is a general question that I have been having for couple of days now and after hours of searching google I am still not sure how it works.Say I have a single pipeline to look for my IaC code change, deploy if there are any changes, and also then build the code and then deploy to the same infrastructure created in the step before.So, it will look something like: PipelineStep1/stage 1:Look for changes in the IaC code (Terraform) and then deploy if there are any changes to .tf filesstep2/stage2:Build the npm applicationstep3/stage3:Run the testsstep4/stage4:deploy the built application to the Infrastructure.Now let's say the if the application fails to build (step2) or if the tests (step3) fail, how do we deal with the infrastructure rollback?

Does anybody know if there is a alternative for azure devops
pipelines?If the alternative you mentioned means some tasks in Azure DevOps pipeline can do the similar thing as 'ankane/setup-mariadb@v1' in GitHub,then the answer is NO.DevOps doesn't have a 'build_in' task like this, even the marketplace also doesn't have a extension to do this.So you have two ways:1, If your pipeline based onMicrosoft hosted agent, everything should be set up via command:How to Install and Start Using MariaDB on Ubuntu 20.042, If your pipeline based onself hosted agent, then you can 'set up' the environment(MariaDB) before start the pipeline. And then use it in your DevOps pipeline.

I want to migrate my github action pipeline to azure devops, unfortunally i wasn't able to find an alternative to the github action "ankane/setup-mariadb@v1".
For my pipline I need to create a local mariadb with a database loaded from a .sql file.
I also need to create a user for that database.
This was my code in my github pipeline:- name: Installing MariaDB
uses: ankane/setup-mariadb@v1
with:
mariadb-version: ${{ matrix.mariadb-version }}
database: DatabaseName
- name: Creating MariaDB User

I don't think there is a general way to break down aggregation stage(s). But for your specific case, your query seems to be trying to perform a common 'lookup-then-combine' operation. The query performs 2 lookups tousersandusertypescollections and 'links' up the lookup results together by ids inside.Anarguablymore comprehensible way to perform the same behaviour would be:Precaution: You can see there is a sub-pipeline inside sub-pipeline. Usually it would be a bad idea as it would make the pipeline complicated and hinder readability. However for your case, it may be ok as we can keep it simple to 1 single$limitstage only. We avoid excessive$lookupto gain some performance.db.workoutDetailSchema.aggregate([
{
"$lookup": {
"from": "users",
"localField": "REF_Users",
"foreignField": "_id",
"pipeline": [
{
"$lookup": {
"from": "usertypes",
"localField": "REF_UserType",
"foreignField": "_id",
"pipeline": [
{
$limit: 1
}
],
"as": "userType"
}
},
{
"$unwind": "$userType"
}
],
"as": "people"
}
}
])Mongo Playground(some wrangling stages are omitted to keep it simple for demo purpose)You can see a sub-pipeline is used to perform another lookup and handle the 'linkage'. Potentially it could be more performant, as it doesn't need to iterate through the lookup arrays.

If you want to run a regular expression outside your usual language/runtime, you should get used to thegreputility.A naive approach for your case:TICKET_NAME=$(echo $BRANCH_NAME | grep --only-matching --extended-regexp 'DOM-[0-9]+')(you might need to workout the actual ticket name regex)Friendly reminder: the branch name is accessible in the$BITBUCKET_BRANCHenvironment variable (for branch pipelines, no custom nor tag-triggered pipelines)
|
I have a bitbucket pipeline where I want to retrieve some part of the branch name (the ticket name)I basically get the branch name with :- BRANCH_NAME="$(git rev-parse --abbrev-ref HEAD)"Now the branch name is likefix/DOM-123-my-ticket-infoI would like to basically do something like- BRANCH_NAME="$(git rev-parse --abbrev-ref HEAD)"
- TICKET_NAME= // a way to retrieve DOM-123 from $BRANCH_NAMEDo you know how would this be possible ?I haven"t find anything on how such a thing would be possible.

This is very long for our CI/CD pipeline.QuestionWhat are alternative ways of addressing missing library stubs?E.g., such that I could maybe 'split' mypyinstall types(or other solution that is more time-consuming and potentially can be put as part of docker image), from purerun mypycommand (that takes less time and runs as part of gitlab ci/cd pipeline).I tried runningmypy --install-typescommand first, and thenrun mypywithout success. Could it be that I am doing something wrong?I will appreciate any help and ideas!

The problem with your code is that items are split into pipeline components, each of which has a different copy of the shell running it in parallel; so a singleifstatement can't have itsfisplit off into a different pipeline component.You can't make a conditional pipeline entry easily, but youcaneasily make a pipeline entry decide whether to run a command that does something (likesort) or one that doesn't do anything at all (likecat).generate_data |
if [ "$want_sorting" = 1 ]; then
sort -k1,1
else
cat
fi |
consume_dataNow, the slightly less-easy approach:To get rid of this copy ofcatone can use a shell function that only conditionally creates the pipeline component withsortbefore running whatever was supposed to come later in the pipe; something like:maybe_sort_then() {
if [ "$want_sorting" = 1 ]; then
sort | "$@"
else
"$@"
fi
}
generate_data |
maybe_sort_then consume_data

I want to conditionally addsortto a shell pipeline, but I'm getting a syntax error when I try:want_sorting=0

Is it possible to set the default value of a choice parameter dynamically to TRUE or FALSE through pipeline script with an input(TRUE/FALSE of that parameter itself)So that in the next execution no need to set the default value again it should take the value from the previous execution until there is a change in choice once again.

found the solution:sh '#!/bin/tcsh \n' +
'source ./mysettings.sh \n' +
'echo "Calling my alias" \n' +
'my_alias \n'every line starting with sh launches a new shell, so it has to be in one line including line breaks.further adding to the confusing was that documentation of jenkins says that it starts "a bash" but it launched /bin/sh which in my case pointed to something else
|
I have a legacy project in Jenkins that hast to be pipelined (for
later parallelization), hence moving from simple tcsh script to
pipelinerunning the script as#!/bin/tcsh
source ./mysetting.sh
updateworks but the same pipeline step fails due to missing alias expansionstage ('update') {
steps {
//should be working but alias expansion fails
sh 'tcsh -c "source ./mysettings.sh; alias; update"'
//manually expanding the alias works fine
sh 'tcsh -c "source ./mysettings.sh; alias; python update.py;"'
}
}calling alias in the steps properly lists all the set aliases, so I
can see them, but not use them.I know in bash alias expansion has to be set#enable shell option for alias_expansion
shopt -s expand_aliasesbut in csh/tcsh that should be taken care of by source.what am I missing?

You could use theManual Validation Task.Use this task in a YAML pipeline to pause a run within a stage, typically to perform some manual actions or validations, and then resume/reject the run.jobs:
- job: waitForValidation
displayName: Wait for external validation
pool: server
timeoutInMinutes: 4320 # job times out in 3 days
steps:
- task: ManualValidation@0
timeoutInMinutes: 1440 # task times out in 1 day
inputs:
notifyUsers: |[email protected][email protected]instructions: 'Please validate the build configuration and resume'
onTimeout: 'resume'

I have two stages in my Azure DevOps pipeline. One with Pulumi Preview (let's call it Preview) and one with Pulumi Up (Up) in order to run my infrastructure as code.Both run from the same container and it takes a while to pull it. I want to manually approve the Preview before the implementation.Can I pull and run the container for both stages simultaneously but wait for the last job of the UP-Stage until the Preview-Stage is approved?Currently they depend on eachother as follows:trigger:
- master
pool:
vmImage: 'ubuntu-latest'
stages:
- stage: Pulumi_Preview
jobs:
- job: Preview
container:
image: REGISTRY.azurecr.io/REPOSITORY:latest
endpoint: ServiceConnection
steps:
- task: Pulumi@1
displayName: pulumi preview
inputs:
azureSubscription: 'Something'
command: 'preview'
args: '--diff --show-config --show-reads --show-replacement-steps'
stack: $(pulumiStackShort)
cwd: "./"
- stage: Pulumi_Up
displayName: "Pulumi (Up)"
dependsOn: Pulumi_Preview
jobs:
- job: Up

Thedefault codecfor an output is plain, and the if the format option is not specified then that willcall the .to_s methodon the event. The .to_s methodaddsthe timestamp and %{host}. You can prevent this by addingcodec => plain { format => "%{message}" }to your syslog output.

I resolved this issue byidentify and close the open handlers by--detectOpenHandles.Divide the test cases in chunks using--matchPathPatternand run those chunks parallel in GitLab pipeline. Generate separate coverage reports and merge using Istanbul-merge.
|
When I run test cases in local. All the test cases are completed within time limit(5000). But, When I run those test cases in gitlab pipeline then it will consume more time.I use gitlab version 10.
|
Why Jest cases takes much more time to run inside the Gitlab pipeline (Throw a timeout error inside pipeline)?

The way I found to solve this problem was adding to the test project structure the generation of an xml with the information I needed. With the generated xml I was able to access it through a Powershell task and then save the variables as needed.

I'm running the task below in Azure Pipelines and I needed to access the percentage of tests passing and failing as a result of running this task in another task.Is this possible to be done? Can I access this result through a variable?- task: DotNetCoreCLI@2

inputs:
command: 'test'
projects: '**\BaseProject.dll'
workingDirectory: '$(System.DefaultWorkingDirectory)'Please can someone help me? Thanks.

you need to add a service connection since you are communicating with the other azure services.you can add service connection in portal it is under the project settings.Select service connection and after that popup will appear on which you have to select docker registryFill the subsequent form about the subscription and ACR detailsAnother approach would be to use docker to pull imagesRefer thisdocumentationabout it.

need some help. I created a custom image that pushes to Azure Container Registry and use it as a based image for the Azure DevOps pipeline, but it seems it does not pull the image.azure-pipelines.ymljobs:
- job: rf
container:
image: test.net/rethrf:8944OutputError response from daemon: Head "https://test.net/v2/rethrf/manifests/8944": unauthorized: authentication required, visit https://aka.ms/acr/authorization for more information.
##[warning]Docker pull failed with exit code 1, back off 2.89 seconds before retry.any solution to this? or did I miss any environment variables?

You can permanently persist all messages sent to a SQS queue by adding a SNS topic in front of it that has an additional subscription. This would be a Kinesis Data Firehose subscription that has a S3 bucket configured as it's destination.That way, any message published to the SNS topic would get sent both to the S3 bucket and the SQS queue. Your SQS DLQ would work the same way as usual, and you could provide a way for clients to query failed messages from the S3 bucket at a later date (potentially much later than the maximum retention policy SQS allows).See the below links for more information:https://docs.aws.amazon.com/sns/latest/dg/sns-firehose-as-subscriber.htmlhttps://docs.aws.amazon.com/firehose/latest/dev/create-destination.html#create-destination-s3
|
Purpose: I created an SQS queue in hopes of storing bad data into a dead letter queue. My goal is to connect SQS to SNS, so that subscribers can get notified of the bad data stored in the dead letter queue.However, I understand now that data cannot be permanently stored through SQS because of its retention period. I also understand that SNS is known for PUSH not PULL, therefore it can't receive the SQS messages and email those messages to subscribersSo, my question is, what is a way to keep the messages from SQS permanently? My goal is to store those messages somewhere safely for future use. I also looked into storing the messages into S3.

The proper syntax isdef data = readYaml file: "cars.yaml"
def brand = data.cars[0].brandYou can find the definition (and examples) in the pipelineutility steps documentation.
|
I have a YAML file template which is set out out like so:cars:
- brand: bmw
fuel: petrol
transmission: manual
- brand: mercedes
fuel: diesel
transmission: auto
- brand: audi
fuel: electric
transmission: semi-autoI am trying to write a function for a Jenkins pipeline that reads through the YAML file, picks up the brand, fuel and transmission value of each array set, and execute commands based on these variables for each set, I assume it would have to be some kind of loop.I have tried using readYaml however it doesn’t seem to pick up the first “brand” in this case and get errors, not sure if this YAML layout is ideal for my use caseI have tried:def cars = readYaml file = cars.yaml
def brand = cars[brand]Expecting echo brand to return a list of brand names, which I can then use to look up the fuel and transmission values of that brand. However I get this errorgroovy.lang.MissingPropertyException: No such property: mkp for class: WorkflowScriptAny ideas?

It isnot possibleto pass/return variables from child pipelines to parent pipelines. We can only pass parameters from parent pipeline to child pipeline.A work around to this problem is towrite the values into a file (txt) in the child pipeline and read this file from parent pipeline. Look at the following demonstration.Let's say you have a text file (with some data) in the storage account. In child pipeline, after thecopy and set variable activitycompletion, create a copy data activity.The source dataset would be the above text filewithoutfirst row as header. Here add additional columns, with your variable values.Select sink (without header). In mappings, import schema and delete the columns that are not required.Invoke this pipeline from parent pipeline, the values will be written as a text file (as shown in the below image)You can finally read this file in parent pipeline (using lookup) and utilize those values.

I have a child pipeline on Azure Data Factory which is called by a master one by an "Execute Pipeline" activity. This child pipeline has a couple of variables which I need in my master pipeline.On this child pipeline I even use some "Set variable" activities to change the variables values. Like in the example:I would like to pass this final values of my variables from child pipeline to the master one. If every step run successfully, my variables would have all "true" values at the end of my child pipeline. I would like this values to be passed to the master pipeline. Like in the example:Is it possible?

To make pipeline dependent on each other you can create a trigger and make those triggers dependent on other triggers.To create dependent pipelines, we can useTumbling window triggerCreate triggers forPipeline to table A, B, CbyTrigger >> New/Edit >> Choose Trigger >> New >> Type-Tumbling window >> Configure Properties >>SaveTo makePipeline to table D, Edependent onPipeline to table A, B, CSelect Trigger > Advanced > New, then choose the trigger to rely on with the proper offset and size. This will create dependent on the trigger.ExampleIn above exampleTrigger 4is created forpipeline 4And in Dependencies added Trigger 1, 2, 3 which are created for pipeline 1, 2, 3 respectively.This dependentTumbling window triggerexecute only when another trigger inside the service has successfully been executed.

I have 5 pipelines on my Azure Data Factory, each pipeline copy data to a different table. There is a dependency on some of this tables, table D & E depend on table A, B & C. Like in this example:Table dependencies & PipelinesWhat I'm doing to refresh all data is the following executing sequence:Exec Pipeline to table A > Exec Pipeline to table B > Exec Pipeline to table C > Exec Pipeline to table D > Exec Pipeline to table E.Pipelines Execution OrderI could execute Pipeline to table E before Pipeline to table D with no problem, but none of them can be executed before Pipelines for table A, B & C.The idea I had to make this more organized and easier to schedule was change the pipeline D and add there 3 steps that will execute the Pipelines for table A, B & C. And on Pipeline to table E I added a step to execute the pipeline D. Like in the example:Pipelines IdeaHowever, this would create a kind of dependency on Table E with Table D, which I don't want. If I need for any reason to update JUST table E, it won't be able because I would need to update table D first.I wanted that both Pipelines to table D & E had a kind of validation if Pipelines to table A, B & C had run so then they can run.Is there a way to make this dependencies more organized?

My solution to this is to place the envmodules in the config file:# config.yaml
envmodules:
stdenv: "StdEnv/2020"
gcc: "gcc/9.3.0"Then you can callconfigfile: 'config.yaml'
envmodules = config['envmodules']
rule test:
input:
text='catthis.txt'
output:
"test.txt"
envmodules:
envmodules['stdenv'],
envmodules['gcc']
shell:
"cat {input.text} > ./{output}"That will make it clearer at the rule which envmodules are expected while allowing you to keep track of versions in one place. I use something similar for containers.If you really want to keep the yaml separate, you can load multiple config files, though that's more challenging to ensure keys are not overwritten.

I have asnakefilelike this (only for dep:rule test:
input:
text='catthis.txt'
output:
"test.txt"
envmodules:
"modules.yaml"
shell:
"cat {input.text} > ./{output}"Mymodules.yamlfile contains this:modules:
"StdEnv/2020",
"gcc/9.3.0"So in the end, I'd like to have something like this, when snakemake is called:rule test:
input:
text='catthis.txt'
output:
"test.txt"
envmodules:
"StdEnv/2020",
"gcc/9.3.0"
shell:
"cat {input.text} > ./{output}"Perhaps this is not possible, but I found nowhere on thesnakemake website herethat would allow this. But I'd be much more practical for me to have one file to call rather than pasting the modules to be loaded in all the rules (here I'm showing one, but imagine I have 50 rules...)When running the snakemake (assuming everything is in the same directory)snakemake -p --cores 1 --use-envmodulesit doesn't work (using themodules.yaml), but it does work if the modules are put directly in thesnakefile.Thecatthis.txtcontains only this textLorem ipsum dolor sit amet, again for demonstration.
