Bug 295726: Poudriere fetch not checking distfiles for lang/python311
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=295726



--- Description ---
System: FreeBSD 15.0
Setup: Individual thick jail on the FreeBSD 15.0 host

Ports Package: https://www.freshports.org/lang/python311 (3.11.15_2 updated on
26MAY2026)

Root Cause: The distfiles, overarching the poudriere build system, did not
check, in the fetch phase if the file has been updated and only confirmed files
existed. This resulted in a checksum error.

Background: Build a custom ggml/llama.cpp package based on CPU instruction
modifications which required the building of python311 to support its
dependencies. Previous builds have occurred

Steps to Reproduce:
1. Create a ports tree, through the poudriere system
2. Compile the llama.cpp through the command: poudriere bulk -j 150Ramd64 -p
HEAD -c misc/ggml misc/llama-cpp
3. Compiles 115 packages
4. Gets to the langchain/python311
5. The Make checksum component looks at the patches
6. The checksum responds with a different checksum result then what is in the
package.

Work-around: Add FETCH_GET=4 to the poudriere make.conf file to retry the
download to resolve the checksum mismatch. Upon the error being detected,
poudriere will redownload the files and the checksum issue is resolved.
