Proposed fix: Remove dependency on System.IO.Compression for .NET Framework build #6192

zacharycmontoya · 2024-10-24T04:09:08Z

Summary of changes

Replaces usages of System.IO.Compression (ZipEntry) with a vendored SharpZibLib

Reason for change

Since System.IO.Compression can be consumed by applications with the out-of-band System.IO.Compression NuGet package, it can potentially cause assembly loading issues. This is the main reason why we do not use System.Net.Http in our .NET Framework build, as we previously observed crashes there.

Implementation details

Vendor in SharpZipLib v1.3.3 (MIT License)
Remove AssemblyReference to System.IO.Compression
Update Datadog.Trace.Logging.TracerFlare.DebugLogReader to use SharpZipLib instead of System.IO.Compression.ZipArchive
Update Datadog.Trace.Trimming.xml Root Descriptors File
Update snapshot tests that assert Datadog.Trace assembly references

Test coverage

Re-uses existing tests for tracer flare which authors the zip files

Execution-Time Benchmarks Report ⏱️

Execution-time results for samples comparing the following branches/commits:

Execution-time benchmarks measure the whole time it takes to execute a program. And are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are shown in red. The following thresholds were used for comparing the execution times:

Welch test with statistical test for significance of 5%
Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).
