docker: Cannot import .xhprof files - PHP Fatal error: require(): Failed opening required xhgui/external/../vendor/autoload.php'

[maltfield]

Attempting to import an .xhprof file into the mongodb fails on fresh install with the following error

root@disp9981:/home/user/xhgui# php external/import.php -f /home/user/some.xhprof
PHP Warning:  require(/home/user/xhgui/external/../vendor/autoload.php): failed to open stream: No such file or directory in /home/user/xhgui/external/import.php on line 5
PHP Fatal error:  require(): Failed opening required '/home/user/xhgui/external/../vendor/autoload.php' (include_path='.:/usr/share/php') in /home/user/xhgui/external/import.php on line 5
root@disp9981:/home/user/xhgui# 

In fact, there is no vendor directory at all. What is it trying to require()?

Problem

There is no vendor/autoload.php file present after doing the Docker install (and not even a vendor directory). This causes attempts to import .xhprof files to fail.

Moreover, /external/import.php is not available from the web server, and it's entirely unclear/undocumented as to how a user is supposed to import .xhprof files into xhgui, as pointed out in this other ticket:

• Where to put the *.xhprof files? #182 (comment)

Expected Solution

1. I should be able to run php external/import.php -f /path/to/some.xhprof and it successfully imports the file into xhgui
2. I should be able to access http://localhost:8142/external/import.php in my browser after installing via Docker
3. It should be clearly documented how I can import a .xhprof file into XHGui after a fresh Docker install

Steps to Reproduce

This bug can be reproduced by executing the following commands on a Debian 11 system:

sudo su -
sudo apt-get install docker.io docker-compose php
git clone https://github.com/perftools/xhgui.git
cd xhgui
git reset --hard 3fb75686aeddb732833982346aaff294ecaaf1ef
docker-compose up -d

Then, copy some.xhprof file to /home/user/ and run

php external/import.php -f /home/user/some.xhprof

Context

I'm running this on an AppVM in QubesOS running Debian 11.

the cli command needs to be run inside the container:

php external/import.php -f /home/user/some.xhprof

but for that to work you need also add extra bind-type volumes to container, so the file is accessible inside the container.

---

the instructions there are old, pre-docker, that assumed you had local installation.

I guess the infrastructure should be re-worked to add cli script to https://github.com/perftools/php-profiler, that could use /run/import endpoint to submit the .jsonl files.

but for that to work you need also add extra bind-type volumes to container, so the file is accessible inside the container.

Sorry, would you mind expounding on this a bit here in the ticket? For the following command to not throw errors, what exactly should I do?

php external/import.php -f /home/user/some.xhprof

I need to add some lines to a docker file? Which file? Exactly what lines do I need to add so that the container has access to the dependencies it needs to run the above script??

[glensc]

1. you need to run the command inside the container, so docker-compose exec xhgui sh
2. in the container, you need to have access to the .jsonl file saved by php-profiler, so you need to add a volume, edit docker-compose.yml and add it, or as config is already in volume, put the file to config dir, and then adjust the import command accordingly.

but really, as I said already, the import script should be probably moved to https://github.com/perftools/php-profiler project

[glensc]

the import cli program was added to this repo:

• https://github.com/perftools/php-profiler

if something unclear or broken, open issue there. or just submit pull request.

currently on main branch only.

[glensc]

and documentation update (in this repo):

• Refactor: Deprecate import script from this project #479

[maltfield]

@glensc first, I do really appreciate your efforts on addressing this issue, especially so fast!

Unfortunately, I think it's now even more unclear to the user how the heck to import .xhprof files into XHGui.

If a distinct tool is needed, then I think the documentation should list exact commands needed to:

1. install the other tool
2. import a .xhprof file into the other tool
3. export the .jsonl file from the other tool
4. import the .jsonl file from the other tool and import it into xhgui

If I'm still totally confused about how to do this, it's probably because the new ignorant user (me) is not able to find any clear documentation on how to do these things...

[glensc]

it is not possible to import .xhprof (I still don't know what does it even contain), as it lacks request information needed by xhgui.

I answered that here:

• Where to put the *.xhprof files? #182 (comment)

the only supported way to profile is this library:

• https://github.com/perftools/php-profiler

that is probably why you can't find any documentation for custom use-cases.

you may try to use classes from perftools/php-profiler to build jsonl files from xprof files, emulating missing metadata, and submit your files yourself. you need some coding expertise to do that. the newly added cli script to run import may be of a good help.
