🩹 Build Failed: Patch Application Failed

Hunk #3 FAILED at 141. 1 out of 4 hunks FAILED -- saving rejects to file build.gradle.rej

Build Details

Category Details
Build System Gradle
Failure Point patch '-p1' --fuzz=2 --verbose <cves-20250220.patch

Root Cause Analysis 🔍

The patch file 'cves-20250220.patch' couldn't be fully applied to build.gradle file. Specifically, hunk #3 (targeting line 141) failed to apply, likely because the target file has changed since the patch was created.

Suggested Changes

File: cves-20250220.patch

  • update at line all (entire file)
    Original:
Current patch content targeting line 141 of build.gradle

Replacement:

Updated patch content that matches the current state of build.gradle

Content:

The patch file needs to be regenerated to match the current state of build.gradle. This would involve:
1. Examining the current build.gradle file to find the correct context around line 141
2. Creating a new patch with the correct line numbers and context
3. Ensuring the patch applies the same functional changes but with updated line numbers and context

File: akhq.yaml

  • update at line patch step (pipeline section)

Analysis

The current build failure shows a patch application error where one of the patch hunks (#3 targeting line 141 in build.gradle) failed to apply. This is a common issue when patches are created for a specific version of a file but then applied to a different version where the context or line numbers have changed.

In the similar fixed build failure (Fix Example #0), the issue was also a patch failure with a specific hunk failing to apply. The solution in that case was to create a completely new package configuration file (kafka-4.0.yaml) rather than trying to patch the existing file. This indicates that when patches don't apply cleanly, one approach is to either update the patch file or bypass the patching mechanism altogether.

Explanation

The build failure is occurring because the patch file 'cves-20250220.patch' contains a hunk (specifically #3 at line 141) that doesn't match the current state of the build.gradle file. This typically happens when:

  1. The upstream code has been updated since the patch was created
  2. Line numbers or surrounding context in the target file have changed
  3. The patch was created for a different version of the file

The suggested fix takes two approaches:

  1. Regenerate the patch file: The most reliable solution is to recreate the patch file to match the current state of build.gradle. This involves examining what changes the patch is trying to make and then creating a new patch that applies those same changes but with updated line numbers and context that match the current file.

  2. Increase the fuzz factor: As a potential workaround, increasing the fuzz factor from 2 to 3 might allow the patch to apply despite small context differences. The fuzz factor tells the patch command how many lines of context can be ignored when trying to find a match. Increasing it might help with minor context differences.

The patch command is already using the -p1 flag (which strips one directory from the patch paths) and the --fuzz=2 option (which allows for some context differences). Increasing the fuzz factor might help, but regenerating the patch is the more robust solution.

Alternative Approaches

  • Apply the patch manually: Instead of using the automated patch process, you could manually apply the changes that the patch is trying to make by examining both the patch file and the current build.gradle file and then making the changes directly in the code.
  • Create a new package file: As seen in the fixed example, one approach is to create a completely new package configuration file rather than trying to patch an existing one. This would mean creating a new akhq version with the security fixes already applied.
  • Split the failing patch: If only one hunk of the patch is failing, you could split the patch into multiple smaller patches - applying the working hunks normally and handling the problematic hunk separately.
  • Use a different patching tool: Some patching tools handle context differences better than others. Consider using a tool like 'git apply' with the '--reject' option, which will apply what it can and generate .rej files for the parts it couldn't apply.
