This repo has some small custom binaries and vendored executables we use for testing some of Parca Agent's features. This lives in a separate repository as we we wanted to commit executables and unwind tables that can be very large.

Structure

• tables/default contains a textual representation of the unwind tables. the names follow the following format "<producer>_<the executable name>.txt". <producer> is the name of the tool that produced the table, "ours" for our implementation.
• tables/compact as above, but using the compact unwind format we use in BPF.
• tables/tables similar to compact tables, but after any processing. These are the ones that would be loaded in the BPF maps.
• jitdump contains the jitdump files for certain executables. These are used to test the JIT dump parser.
• out/ has the produced executables for our custom programs.
• src/ contains the source for our custom programs.
• vendored/ hosts prebuilt executables.

Building

To build the executables, run mage build:all or make build. This will build the executables and place them in out/.

Adding new tables

To add a new table, run mage generate:all or make generate. This will build the tables and place them in tables/default/,tables/compact/ and final_tables/.
