partial logs not showing colors

[AvihayTsayeg]

follow to #212

• Jenkins Version:2.263.1
• AnsiColor Version: compiled the branch of tszmytka:212-partial-log-output
• Operating System running Jenkins: Ubuntu 14.04.6 LTS

repreduces: free style job

#!/bin/bash
set -x
for i in {1..5000}; do  
echo -e $i '\033[0;37;42m[10]\033[0m \033[32m  my letters\033[0m'
done

[tszmytka]

@AvihayTsayeg Thanks for the report and the example. I needed to beef it up a little (it had no ESC bytes).

The issue is fully reproducible. Plugin doesn't kick-in in a partial log output of a "Freestyle Project". Most of the time I use pipelines (where an equivalent script would work fine) so it slipped under my radar.

[tszmytka]

Only now that I have a longer moment I see that the version I could reproduce this in was ansicolor-0.7.3 - the one still not having #214 .

After merging everything I am no longer able to reproduce the issue. I've just released ansicolor-0.7.4.

@AvihayTsayeg Could you please install the newest version and post the results?

[avihaycloudinary]

Many thanks 🙏 !!! I will install it soon, will let u know during the week. We have many builds and I want to check them all.

[AvihayTsayeg]

@tszmytka Still there is an issue, We are using pipline, but for simplicity my examples are freeform. This image is after installing the new version.

[tszmytka]

Let's stick to comparing apples to apples.

1. Can you please run the example you provided in the issue description?
2. Could you also go to the update center's installed tab (your-jenkins-url/pluginManager/installed) and post a screenshot showing ansicolor plugin?

[AvihayTsayeg]

finally could restart jenkins,

[tszmytka]

Please use example from the issue description - the one I updated with ESC bytes (\033). At best copy-paste it into a new "Freestyle project" job having only "Color ANSI Console Output" option checked.

If you have any of the following plugins installed, please provide their versions:

• Timestamper
• Kubernetes plugin

Are you running the job directly on the jenkins host or by means of agents? Maybe through docker and/or k8s?

[AvihayTsayeg]

We do not use Kubernetes plugin,

the result for \033 are just fine.

The main issue is some builds the log is fine and some not, I suspect the issue is the place which the log is getting cut for partial log.

[tszmytka]

the result for \033 are just fine.

Ok, this means the script you've been using in issue description contains control characters that interfere with the whole processing. Here's how you posted it before my adjustment:

#!/bin/bash
set -x
for i in {1..5000}; do  
echo -e '[0;37;42m[10]�[0m �[32m  my letters'
done

The control characters probably have gotten garbled into � - which makes it impossible to reproduce (� doesn't trigger ANSI sequence processing so output remains as-is in both short and long console output).

Can you check what these characters are? Or better yet - can you put your original script into a file and attach it to the issue? Please make sure it is the one that produces output exactly as shown in issue description screenshot.

[AvihayTsayeg]

I have create a gist see how it looks in editing note the red dots, after save the dots disappeared.

link to gist https://gist.github.com/AvihayTsayeg/bba2eb6dc955bffbfc792b9e86c3bed5

[tszmytka]

Luckily github leaves control characters in gists. Both of the invisible characters are ESC - this should all be working correctly and indeed is working on any jenkins I've tested it with (with ansicolor 0.7.4 obviously).

One thing that is different with my output and screenshots from issue description is that your run seems to produce more (by about 9KB) output. Is any other option enabled/set/filled in your job configuration apart from "Color ANSI Console Output" and "Command" textbox filled with the script? Also could you run the following script in your script console (your-jenkins-url/script) and post the results:

Jenkins.instance.pluginManager.plugins.each{
  plugin -> 
    println ("${plugin.getDisplayName()} (${plugin.getShortName()}): ${plugin.getVersion()}")
}

[AvihayTsayeg]

@tszmytka Sent u mail with the complete plugins details

the diff size might be to set -x ?

[DavidPerezIngeniero]

Confirmed with:

• AnsiColor 0.7.4
• Jenkins 2.263.2
• Java 11
• Amazon Linux 2

[AvihayTsayeg]

I think the set -x is causing this issue in the example I sent. without it it is working fine on my Jenkins

without set -x

[tszmytka]

@AvihayTsayeg

Sent u mail with the complete plugins details

Thanks - got it. Feel free to remove your content if you don't want it to hang in the net.

I think the set -x is causing this issue in the example I sent.

This is a very interesting finding - thanks for that. I used set -x in all my successful runs so it can't be the only reason but I will try to play around with it - seems like a good lead.

[DavidPerezIngeniero]

Any workaround? Maybe an older version of Jenkins or the Ansi plugin?

[roehrijn]

I can confirm this. There is still an issue after #214. In the case I start viewing the log on the very beginning of the job everything works as expected. But when opening the console after the a while or even after the finished and when Jenkins displays the partial log output message, I see raw ansi escape sequences and no colors.

Upgrade 0.7.5 did not solve the problem. I'm using Jenkins 2.271.

The logs are coming out of a pipeline execution from a slave node which is running on the same machine. Neither timestamper nor kubernetes / docker plugins are installed.

[roehrijn]

Please have a look into the proposed #220. I noted down some thoughts about the cause of the problem after some debugging sessions and proposed a fix, which I know, is not going to solve all aspects of the problem.

[JiffsMaverick]

Confirmed with:

AnsiColor: 0.7.5 Jenkins: 2.277.1 Java: 1.8.0b201 OS: CentOS 7.6

But AnsiColor 0.5.3 - works ok.

[nuBacuk]

Jenkins: 2.235.2 AnsiColor: 0.7.5

I confirm the problem, I have a log of about 130kb from the ansible, and part of the log is colored and part is not. I tried to put the version AnsiColor 0.5.3 - not work.

[DavidPerezIngeniero]

I confirm that downgraded to version 0.5.3 and works flawlessly! :-)

[roehrijn]

Hi @nuBacuk, could be you're hunting a different bug than me, @JiffsMaverick, @DavidPerezIngeniero for example. I think there is a difference between having no color at all in case the log is shown only partially in case it is too big and no color showing after a while in the log, but all the log is displayed.

0.5.3 also works for my usecase.

[tszmytka]

To anyone experiencing this problem: Could you please post the actual job/pipeline that you are using and a screenshot of the output? I have not been able to reproduce this bug with the script posted in the initial description till this day.

[roehrijn]

I did further analysis and now can say that the bug was introduced by b1336fd and a5d7d8c. Thus, ansicolor-0.6.3 is the last version without this bug.

b1336fd does not compile and a5d7d8c is fixing that together with a lot more other stuff. That's why I currently can't say which of both exactly introduced it.

I'm able to reproduce it on Linux with the Bash script above in a freestyle job with nothing more than the ansicolor checkbox ticked and the script added as a "script" build step.

I'm also able to reproduce it on Windows with similar setup but replacing the Bash script with this Windows Batch script:

This script is from https://ss64.com/nt/echoansi.txt and slightly modified to run in a loop.

[roehrijn]

and @tszmytka, this is the screenshot of the output:

[roehrijn]

Again new findings:

Until 0.6.x I can reproduce the bug with exactly the setup in this repository. Just by checking out and running mvn hpi:run. Starting with 0.7 I can't reproduce it in all cases, but I can reproduce it when I show the log of a currently running build which is already that far that the console log is showing only partly. In this case it is shown without colors. When reloading the console after the build has finished, color are shown.

The issue is located in ColorizedAction.java:

    public static ColorizedAction parseAction(String lineContent, long lineNo, Run<?, ?> run, LineIdentifier lineIdentifier) {
        return run.getActions(ColorizedAction.class).stream().filter(a -> lineIdentifier.isEqual(lineContent, lineNo, a.id)).findAny().orElse(CONTINUE);
    }

In case the build is finished, run.getActions(ColorizedAction.class) retrieves two ColorizedActions, one with a UUID as id (the one which could also be found in the build.xml of the build) and one containing the hash of the first displayed line as id. This prevents that function from returning the CONTINUE-Action. In case the build is not yet finished but far enough to only show a partial log, run.getActions(ColorizedAction.class) retrieves only the action with the UUID. Which leads to the CONTINUE-Action to be returned.

[tszmytka]

@roehrijn Nice idea with the windows batch script, didn't even expect the os to be capable of rendering ANSI escape codes. Can you write which ansicolor and Jenkins versions you were using while getting the screenshot?

I ran it on my end with ansicolor-0.7.5 in Jenkins 2.204.6, 2.260, and 2.271 and it renders output with colors just fine. Another thing, just to be 100% sure we are talking about the same problem: Clicking on Full Log shows colors correctly right? It is only the tailed output that doesn't do that, correct?

Re.

but I can reproduce it when I show the log of a currently running build which is already that far that the console log is showing only partly. In this case it is shown without colors.

I haven't tested such a case but thinking about this now I can confirm that tailed output won't be colored while the build is running. Current implementation simply doesn't have this covered. Either way this is a separate issue - let's focus here on what happens after build has finished.

[thenom]

I have the same issue but i have found why we have the issue.

Jenkins: 2.263.4 AnsiColor: 0.7.5

To confirm our issue, while the job is running, the output is correct all the way up to completion. When we refresh the page or revisit it, the problem occurs. I have found a fixed (in our use case) and can replicate:

This pipeline job works fine including after refresh:

ansiColor('xterm') {
    node {
        stage('test') { // for display purposes
            sh 'printf "\\e[31mHello World\\e[0m\\n"'
            sh 'printf "Normal \\e[1mBold\\e[0m\\n"'
            sh 'printf "Normal \\e[4mUnderlined\\e[0m\\n"'
        }
    }
}

But we use the logstash plugin to output the logs to ES so the actual setup we use is this:

logstash {
    ansiColor('xterm') {
        node {
            stage('test') { // for display purposes
                sh 'printf "\\e[31mHello World\\e[0m\\n"'
                sh 'printf "Normal \\e[1mBold\\e[0m\\n"'
                sh 'printf "Normal \\e[4mUnderlined\\e[0m\\n"'

                sleep 5
            }
        }
    }
}

The output is fine during the run (had to put a sleep in to see the job showed correctly during the run) but after refreshing i get the issue: If i switch around the logstash and ansi classes it works fine:

ansiColor('xterm') {
    logstash {
        node {
            stage('test') { // for display purposes
                sh 'printf "\\e[31mHello World\\e[0m\\n"'
                sh 'printf "Normal \\e[1mBold\\e[0m\\n"'
                sh 'printf "Normal \\e[4mUnderlined\\e[0m\\n"'

                sleep 5
            }
        }
    }
}

[manosnoam]

The issue is reproduced on version 0.7.5 on Jenkins 2.277.2, with freestyle job. It only occurs while the console output is still in progress, so it shows for example: [33mThis should be yellow text

Notes: 1) If going to /consoleFull page - Then Ansi colors are shown correctly. 2) Once the build completes, refreshing the /console page also shows Ansi colors correctly.

[tszmytka]

@manosnoam Your problem seems to be a separate thing. This issue is about log output not getting interpreted by ansicolor after build completes. As you wrote - yours looks fine. Please open a new issue with example pipeline where this is observable.

[tszmytka]

This is a shot in the dark but ansicolor-1.0.0 has just been released. It includes fixes for a couple of bugs that might have contributed to this issue as well. I would encourage everyone to try it out and report back the results.

[madmanidze]

Issue not fixed, same look on partial logs.

[martincermak]

Still the same - unformated partial output

• Jenkins 2.263.3
• ansicolor 1.0.0
• timestamper 1.13
• still running dinosaur OS: Debian Stretch

Upgraded from ansicolor 0.7.4. Last known working version to us was ansicolor 0.4.2. Doesn't matter if the job is running or finished.

NB: jenkins container has docker-cli installed and talks directly to the host docker deamon using docker context. Script output is formatted with bash printf. It use tput for colors etc.

# This is an example, a bit of cut n paste
export _bash_prefix=[$(tput setaf 6)$(tput bold)DOJO$(tput sgr0)] 

declare _bold="$(tput bold)"
declare _nrm="$(tput sgr0)"

declare _cyan="$(tput setaf 6)"
declare _bcyan="$_bold$_cyan"

_hello () {
  wc="$1"
  string="$2"
  printf "%s %s\n" "${_bash_prefix}" ""
  printf "%s %s\n" "${_bash_prefix}" "${_bold}------------------------------------------------------------------------"
  printf "\n"
  printf "%s\n" "${_bcyan}$(figlet -w $1 -c  $2 )${_nrm}"
  printf "\n"
  printf "%s %s\n" "${_bash_prefix}" "${_bold}------------------------------------------------------------------------"
  printf "%s %s\n" "${_bash_prefix}" ""
}

Env:

• jenkins 2.314 from docker jenkins/jenkins:slim-jdk8
• ansicolor 1.0.0

[orzechszek]

Issue stil exists on:

• jenkins 2.317
• ansicolor 1.0.0

[orzechszek]

Any updates?

[dblock]

@orzechszek nope

Still happening on Jenkins 2.336 and ansiColor 1.0.1

Following the console log is nearly impossible. I often see black text on black background which is only fixed once the job completes.

Still happening on [Jenkins 2.346.3] and ansiColor 1.0.2 (it shows correctly during the build, and again problem when build is finished)

[shinebayar-g]

This is a really nice plugin. Unfortunately run into this bug. Reproduced with instructions on the README.

Jenkins: 2.346.3 Latest LTS as of this moment AnsiColor: 1.0.2

pipeline {
    agent any
    options {
        timestamps()
        ansiColor('xterm')
    }
    stages {
        stage('Build') {
            steps {
                echo '\033[34mHello\033[0m \033[33mcolorful\033[0m \033[35mworld!\033[0m'
            }
        }
        stage('Test') {
            steps {
                echo 'hello from test step'
            }
        }
        stage('Deploy') {
            steps {
                echo 'hello from deploy step'
            }
        }
    }
}

1. Stage logs don't render Ansi Colors

   

2. Console Output menu renders Ansi Colors correctly, only in full log mode or output is not trimmed. Doesn't render correctly if console output is trimmed. Screenshot not included for buggy case as my example output wasn't trimmed.

   

3. Build -> Pipeline steps -> Console Output doesn't render correctly (probably same as number 1). This was really unfortunate, individual step logs are much more useful than whole Console Output.

Pretty please, would help greatly :) Thanks!

To fix it, you need to go to Settings ---> Ansicolor ---> Global color map for all builds ---> and set it to xterm.
