T15469: PHP 8.1 "strlen(null)" exception calling Conduit's user.whoami
Summary

strlen() was used in Phabricator to check if a generic value is a non-empty string.
This behavior is deprecated since PHP 8.1. Phorge adopts phutil_nonempty_string() as a replacement.

Test Plan

The following python script executes the user.whoami conduit call

user.whoami.py
import json
import requests
import sys

phabricator_url = sys.argv[1];
api_token = sys.argv[2];

def call_conduit(method, params):
    params['api.token'] = api_token
    response = requests.post(f'{phabricator_url}/api/{method}', data=params)
    return json.loads(response.text)

result = call_conduit('user.whoami', {})

print(result)
Execution in bash
export phabricator_url=http://phorge.blackbird.turdus.localphabricator_url
export conduit_api=api-abcdef1g2hijk45lmnop6qrs7tu8
python3 user.whoami.py $phabricator_url $conduit_api

Thanks again for this patch

If you can, please try to "land" this :)

In short, using Arcanist, you can download the patch, and then "land" that into the master branch:

arc patch D25267
arc land

I'm sorry I didn't know I had to more.

I'm totally new with this arc tool.
The arc patch command did work, but the arc land command returned this:

 STRATEGY  Merging with "squash" strategy, the default strategy.
 SOURCE  Landing the current branch, "arcpatch-D25267".
 ONTO REMOTE  Landing onto remote "origin", the default remote under Git.
 ONTO TARGET  Landing onto target "master", the default target under Git.
 INTO REMOTE  Will merge into remote "origin" by default, because this is the remote the change is landing onto.
 INTO TARGET  Will merge into target "master" by default, because this is the "onto" target.
 FETCH  Fetching "master" from remote "origin"...

  $   git fetch --no-tags --quiet -- origin master


 INTO COMMIT  Preparing merge into "master" from remote "origin", at commit "c300f0e87416".

 <!> UNKNOWN REVISION 
Unable to determine which revision is associated with commit "9c37f16f7a63".
Use "arc diff" to create or update a revision with this commit, or
"--revision" to force selection of a particular revision.

 USAGE EXCEPTION  Unable to determine revision for commit "9c37f16f7a63".

I guess it didn't work...

git status returns this:

On branch arcpatch-D25267
nothing to commit, working tree clean

and git log shows the D25267 commit at HEAD

I don't know what to do here.

OK don't worry, you are almost there!

In that branch, just try updating this page first:

arc diff --update D25267

And then retry:

arc land

I uncommented a line in the editor executed by arc diff and it seemed to work

The arc land however returned this:

Mistery resolved! Git was right. The patch was not successfully land-able since the kind user @aklapper already landed a fix for this 3 days ago

Ouch :D

Thank you very much anyway @mturdus - For consolation, you unlocked this command:

arc anoid

Do you want an help to land this? (No problem, in case)

mturdus added a comment.Jul 24 2023, 14:30

I'm not sure if I understand your question.
I thought the fix was already implemented by aklapper?
What do you want me to do?
