macOS Sonoma - pyodbc 5.0.0b2 crashes - zsh: bus error python3 #1284

Closed carlashley closed 9 months ago

Please first make sure you have looked at:

Environment

To diagnose, we usually need to know the following, including version numbers. On Windows, be sure to specify 32-bit Python or 64-bit:

Issue

When calling pyodbc.connect(dsn, ansi=True), it terminates with zsh: bus error python3 as the error; expected behaviour is the connection is established without crashing.

dsn="DSN=[redacted];UID=[redacted];PWD=[redacted];Encrypt=YES;TrustServerCertificate=YES;sslca=/usr/local/etc/openssl/certs/[redacted].crt"

I haven't been able to catch a crash log for Python 3.12, but the issue occurs with pyodbc 4.0.39 and Python 3.11.6. Issue is not present when using pyodbc 4.0.34 and Python 3.10.10.

Could you try using the official Microsoft ODBC Driver for SQL Server and see if the same crash reproduces there?

carlashley commented 1 year ago

Ah, seems like Microsoft ships their ODBC driver via homebrew (I can't use homebrew in my org on Macs for various internal reasons). I'll see if I can install it without homebrew and update the ticket if it works.

v-chojas commented 1 year ago

You can download driver directly from the links in here: https://github.com/microsoft/homebrew-mssql-release

carlashley commented 1 year ago

Sorry I haven't got back, got distracted with other issues.

I've installed the MSSQL driver into /usr/local matching all the relevant paths per the downloaded arm64 tarball that the MS homebrew recipe downloads, and I've configured odbcinst.ini with the driver details, etc, but I bump into the same problem as #1116 , except of course all the file paths are based in /usr/local/...

I'm not bothered by the openssl error thrown by isql as it suggest to me that isql is working fine with the MS driver (but fails because it can't find openssl libraries where it's expecting them, this is a "stock" install of macOS with the standard openssl included in the OS).

This Can't open lib '/usr/local/lib/libmsodbcsql.18.dylib' : file not found error occurs in Python 3.10.10 to 3.12 (the system hardware and OS is the same, M1 Mac, macOS 14.0).

carlashley commented 1 year ago

Just noting here, I've installed pymssql v 2.1.5 (compiled), to test if that would work, and it is working fine.

If I use Python 3.10, as per earlier comments, it works fine.

I've been able to get approval to use homebrew on a test machine....

Running macOS 14.1 (23B74) with brew versions of unixodbc installed and the Microsoft SQL driver installed as per, and installing pyodbc with pip3 install --no-binary :all: pyodbc, can confirm that pyodbc works as expected.

I need to do a test on another machine that is a fresh macOS install to verify if the self compiled unixodbc + freetds is failing and that it's not something related to my OS install.

We've just released 5.1.0 with binaries for both ARM & Intel Macs. Can you try this version?

I'm going to close this for now since it is pretty old and we have other Mac issues and discussions. Feel free to reopen if this is still a problem.
