I tried to originally remove few jenkins bots (making comments to gerrit reviews based on build results) from gerritstats but it didnt seem to work. Help says following:

--exclude If specified, the comma-separated list of identities will be excluded from all generated statistics. Default: []
I passed "jenkins,fin-jenkins" but neither of the accounts where removed from statistics. Fix was quite evident after browsing the javascript: exclude expects emails.

However, in my case, one of the bot does not provide email in their gerrit messages so gerritstats is not able to remove it.

This is another usecase for supporting mailmap - bots/people who do not have proper git config setup can then be fixed/grouped into a single user during generation of the stats. See #26

Hi, nice tool for per-person stats, is there a possibility to generate cumulative per-project stats?

Nothing happens when I click on the shortcuts at the top of the user page (Overall/Reviewers and approvals/Iteration/Per-month/Comments) when I generate stats for my server, although they do work on the demonstration page at https://gerritstats-demo.firebaseapp.com.

Any suggestions would be most helpful.

Hello guys,

My question is how Gerrit stats connects on gerrit server, and what kinds of permission the gerrit server must provide in order to gerrit stats works fine. I don't start to use this tools yet, because I would like to get these informations in order to confirm whether my server is able to provide the data that gerrit stats needs.

Thank you!

while executing ./gradlew assemble getting BUILD FAILED.

It seems that the documentation lacks information about how to gather data from multiple gerrit instances and multiple projects.

The idea of downloading all projects where you have access to does not make any sense for anything else than very small deployments.

We use 4-5 instances, one internal and the rest public, like gerrithub.io which is HUGE and where we have projects under multiple organizations, so we need a way to gather these in a single place.

Sum the insertions and deletions per author to display in an overview.

Nice-to-have: perhaps some kind of chart over time, showing lines changed (added/removed). Consider this similar to the "Contributors" chart in GitHub. Similarly, rather than breaking down to commits per month and comments per month, also consider SLOC-changed per month, especially over time.

Reason for this is that sometimes commit velocity is not sufficient to give a good indication of what kind of work is being done. But SLOC insertions/deletions over time might be a better view (for some people). So having the option to see both views, or combination (like average SLOC per commit) would help give more detail.

Hi,

Since the list of users is pretty long in our case . I was wondering if we could add a filter for the user in the overview section and what changes might be going in for the same.

As per the title, it looks to me like the option mentionned in the README does not exist anymore.

Also, using "git log -p -S list-commits-exceeding-patch-set-count", I stumbled upon a related commit b9a5ba7 :

But even trying to use "commit-patch-set-count-threshold" did not quite work for me and it looks like this was deleted with 1b08f25 :

On the particular instance of Gerrit I am using, the link to comments do not work. In fact, it looks like the format of the link has changed at some point (removing the "/#/c" part) and the gerritstats code was not updated accordingly.

If anyone is facing the same issue, here is the fix to change things:

+++ b/GerritStats/src/main/frontend/profile/ReviewCommentsPanel.jsx

I do not know when the format got changed on the Gerrit side but it is it old enough, I'm happy to provide a PR for this.

Instead of issuing SSH calls, it would be more portable and future-proof to use Gerrit's REST API instead. At least two serious libraries already exist, gerrit-rest-java-client and org.eclipse.egerrit.core. It's probably a good idea to look at these and take either one into use.

Hi,
while running these scripts it tries to find JAR files but they are missing.

We have BUGID mentioned inside every commit message, like below.

Is it possible to parse commit message for BUGID and make it available in analytics report ?

According to -
https://gerrit-documentation.storage.googleapis.com/Documentation/2.13/rest-api-changes.html#revision-info
kind can get 5 values -
REWORK, TRIVIAL_REBASE, MERGE_FIRST_PARENT_UPDATE, NO_CODE_CHANGE, and NO_CHANGE.

Your code is missing MERGE_FIRST_PARENT_UPDATE

Hi,

It looks like the npm 3.10.5 package in the dependencies is corrupted and the shasum check fails.

For some reason its unable to find the json file even though I see the json file in the gerrit_out dir and has all the data in it.

Hi,

I have tried to execute a downloader command to get JSON data. But it failed at point of command execution , due to some permission issue.
My project is maintained at gerrit. and i have generated keys and registered to gerrit server also.
Command executed :
./gerrit_downloader.sh --server MyServerName --project MyProjectName --limit 10 --output-dir MyOutput/

Output :

Extend the gerritstats downloader to query the REST API via HTTPS using curl or wget. This will allow use of this stats tool on gerrit repositories that block access to statistics by SSH but grant access via anonymous HTTPS.

Unfortunately the protocols are sharply different. The SSH access path is script friendly; the REST API is machine friendly. Both return JSON, but formatted significantly differently.

https://gerrit-review.googlesource.com/Documentation/rest-api.html

In the HTML page, we want to see the lines of code modified also and the lines of code reviewed by each person. Please let me know how we can modify the code to achieve this.

Hi! Great project, thank you so much for sharing!

I get some warnings when running npm install in GerritStats:

npm WARN [email protected] requires a peer of react@^0.14.0 || ^15.0.0 but none was installed.
npm WARN [email protected] requires a peer of react-dom@^0.14.0 || ^15.0.0 but none was installed.
npm WARN [email protected] requires a peer of node-sass@^3.4.2 || ^4.0.0 but none was installed.

And then when running ./gerrit_stats.sh i get a looooot of Module not found:.

When I hover over one of the entries in the Iteration timeline for pages that I have generated on my Gerrit server the current date and time is shown below the circles in the graph instead of the correct date and time, although this works correctly on the demonstration page at https://gerritstats-demo.firebaseapp.com.

After json data created by GerritStatsDownloader, then execute gerrit_stats.sh, but the out-html displacedall “Anonymous Coward” in “Users in analysis ”, while the name info in Overview item are all correct.
How to change the configure or settings?

Is there a way to run the statistic only on commits with status merged and filer out commits with status abandoned or still in progress?

Hi,

Limit parameter is not working as expected. whether will give --limit 10 OR --limit 1, in all cases , Its downloading last 500 commits gerrit data of Project. Please let me know , If below command is incorrect .

./gerrit_downloader.sh --server MyServerName --project MyProjectName --limit 10 --output-dir MyOutput/

In some cases, developers tend to have quite lax behaviour when it comes to setting up their user.name & user.email settings to the git repo they are working on. This leads to scenarios where a single user can be shown as multiple users if she has made commits/reviews with different settings.

Git itself has a functionality to map these cases into a single user via "mailmap" file. See: https://git-scm.com/docs/git-shortlog#_mapping_authors - this sort of a map file is used by other tools also like gitstats ( https://github.com/hoxu/gitstats )

I think it would be a good feature get a author mapping also to gerritstats.

Each commit contains a size of add/removed lines.
It would be helpful to have stats on changes size (to encourage working in small changes)
It could be something like avg. change size.

I'm trying to build gerritstats by following the readme on ubuntu 14.04.

It first complained that npm wasn't installed, so I apt-get'ed it.

It then complained that node wasn't installed, so I apt-get'ed it too

It then fails with:

• What went wrong:
  Execution failed for task ':GerritStats:npmInstall'.

Process 'command 'npm'' finished with non-zero exit value 1

It might be due to legacy node, since it says it's replaced with nodejs. But nodejs is installed. So, I don't know. Does any of this sound familiar?
