Error loading SP #466

Closed waldotf closed 1 year ago

waldotf commented 1 year ago

This is almost certainly a system configuration issue on my end, but I'm getting the following when I try to load SP:

As you'd expect, this causes many plugin features to misbehave/segfault/etc. Guessing this is a system config issue, though I do have the required libs installed. Here's sp info:

What do you get when launching with +developer 1 as well as having your logging level (into ../cfg/source-python/core_settings.ini) set to 5? Also, what is the output of version?

Your ../addons/source-python/data/source-python/* directory appears to be missing entirely. My first guess, would be that the data update failed somehow (or, at the very least, its extraction didn't succeed). Try to delete your ../addons/source-python/data/source-python-data.zip file and restart your server.

Another restart looks the same as the original log. Not sure if it's what matters here, but here's the installed zlib:

jordanbriere commented 1 year ago

Another restart looks the same as the original log.

That's because SP assumes the data is up-to-date since the zip's checksum is the same. A quick google search for cat: hlds.7.pid: No such file or directory yielded the following thread as first result: tf2 crashing 'cat: hlds.13915.pid: No such file or directory'. Perhaps it can points you in the right direction.

Ayuto commented 1 year ago

Maybe the server is unable to extract the new data, because of a permission problem?

waldotf commented 1 year ago

I tried a few extra library packages suggested in various posts without success. All of srcds/ is owned by the user which is running the server process.

I pared out _unpack_data from https://github.com/Source-Python-Dev-Team/Source.Python/blob/1f87696909a95ec1177c6b96f7602b2ec75fdb87/addons/source-python/packages/source-python/core/update.py#L311 into a simple test.py: 

from zipfile import ZipFile

def _unpack_data(path):
    """Unpack ``source-python-data.zip`` into the given path.
    :param Path path:
        The path the data file should be unpacked into.
    """
    with ZipFile("source-python-data.zip") as zip:
        zip.extractall(path)

_unpack_data("source-python-data-test")

and that extracts fine as the same user, using the system Python (3.7.3). If I put that in tf/addons/source-python/data/source-python and restart, everything works as expected (i.e. this seems to be the only issue).

Since it's getting to this log line https://github.com/Source-Python-Dev-Team/Source.Python/blob/1f87696909a95ec1177c6b96f7602b2ec75fdb87/addons/source-python/packages/source-python/core/update.py#L317 and failing to extract, my guess is it's something specific to SP's Python install. Is there an easy way to invoke that?

waldotf commented 1 year ago

Looks like Zipfile isn't threadsafe in our version (fix only backported as far as 3.7). Not sure if that's relevant at all.

The crash is definitely isolated to that call, but I can't reproduce it outside of SP and I don't know how to get a proper backtrace for it with gdb because of all the forking in srcds.

jordanbriere commented 1 year ago

Very unlikely, because the extraction is done on the main thread.

The crash is definitely isolated to that call, but I can't reproduce it outside of SP and I don't know how to get a proper backtrace for it with gdb because of all the forking in srcds.

If you look at the debug.log generated, it should contain the entire stacktrace. I suspect one of the call is not resolved from the right shared library likely due to a mis-configurated multiarch or something. More than likely zlib (or one of its dependencies). Try to run ldd on addons/source-python/Python3/lib-dynload/zlib.cpython-36m-i386-linux-gnu.so.

waldotf commented 1 year ago

Oops, looks like I was invoking srcds_run weirdly and that prevented it from properly preloading -- using either zlib 1.2.3 or 1.2.5 fixes the issue.

The system (Debian 10) version was 1.2.11, which didn't work. Debian 9 repos (out of support since 2020-07-06) have 1.2.8, which did work.

Thanks a ton for the help.

jordanbriere commented 1 year ago

Theoretically, pre-loading your installed version (/lib/i386-linux-gnu/libz.so.1) should do the trick as well, but you may face different issues in different contexts. Actually, for science, could you test it out? I don't currently have time to go in details, but I will explain what is going on and why it happens in a few hours.

waldotf commented 1 year ago

Preloading the installed library version does make it work, that's some cool black magic.

jordanbriere commented 1 year ago

Alright so, as promised, here are some details. The problem is that, on TF2, replay_srv.so is statically linking to zlib 1.2.5:

And is globally exporting all of its symbols:

This is problematic because, while the initial call to inflateInit2 properly resolve to zlib, the subsequent calls it internally does are resolved to replay_srv. More precisely, the following call into libz.inflateInit2:

    ret = inflateReset2(strm, windowBits);

Is effectively invoking replay_srv.inflateReset2 instead of libz.inflateReset2. So, if the installed version of zlib is different than 1.2.5, the behaviours are basically undefined because structures and behaviours may or may not differ. In this specific case here, z_stream_s.zalloc() appears to actually call z_stream_s.zfree() instead... which obviously is not good, heh.

Anyways, pre-loading zlib ensure all symbols we dynamically lookup resolve before the ones exported by replay_srv.

In conclusion, although I'm quite confident pre-loading any version should suffice, I'm not 100% sure it won't result into different issues (e.g. pointers allocated from 1.2.5 being passed around the pre-loaded one, etc. if any other binary is dynamically resolving symbols). So, using 1.2.5 is probably for the best so that everything is consistent regardless of the resolutions.

waldotf commented 1 year ago

That's pretty annoying; I guess it makes sense though. I'm baking this into a Docker image so I'll just include the 1.2.5 binary and preload it to be safe (and avoid ancient repo purgatory). I'm definitely impressed you figured it out.

Doesn't seem like this is really an SP issue at all, just another "srcds is jank" thing. Still, thanks for the help and hopefully this is helpful to someone in the future.

jordanbriere commented 1 year ago

Out of curiosity, what is the console output you get with the following (without preloading anything, and deleting your source-python-data.zip so that it is being extracted): [removed attachment]

Looks like that works as intended.

Nice! That means programmatically preloading zlib prior to loading Python is enough to take priority over replay_srv. I included 1.2.11 because this is the version Python 3.6.1 is built against. Moreover, zlib's manual states that as long as the first digit matches, it should be backward compatible. The other way around not so much due to missing symbols as we've seen here. I will push the changes shortly.
