+# Tests for basic Debuginfod functionality
+
+Because the Debuginfod protocol is a simple HTTP path-based system, one can
+mimic a Debuginfod server by setting up a directory structure to reflect the
+protocol properly. That's how all these tests operate. We override the default
+`DEBUGINFOD_URLS` property with a `file://` URL and populate it with the symbol
+files we need for testing.
+
+## Baseline capabilities
+
+Things to test:
+
+- Just for sanity, the `-no-locator` tests validate that lldb works as the test
+ expects if the files that Debuginfod _should_ provide are already there.
+- Validate that symbols _aren't_ found without Debuginfod, to ensure they
+ weren't cached from previous runs (`-negative` tests).
+- Validate that the Debuginfod symbol locator is providing the expected symbols
+ when the debugger doesn't already have them available.
+
+## Symbol "Configurations" to test
+
+There are 2 top level configurations, each of which then get some post-processing.
+- The 'normal' build: a simple binary built with debug information (`-g`)
+- The 'split' build: A binary built with `-gsplit-dwarf` that produces `.dwo` and `.dwp` files
+
+For the normal build there are 2 post-processing steps where Debuginfod may be used.
+- Strip the binary while hosting the full, unstripped binary on a Debuginfod server.
+- Strip the binary and produce a corresponding 'only-keep-debug' version of the binary to host on a Debuginfod server.
+
+For the split build, there are *3* post-processing outcomes where Debuginfod usage makes sense:
+- Stripped binary, hosting the full unstripped binary on a Debuginfod server, along with it's `.dwp` file.
+- Stripped binary, hosting the 'only-keep-debug' version of the binary *and* it's `.dwp` file.
+- Unstripped binary, hosting only the `.dwp` file on the Debuginfod server.
+
+For both normal and split builds, when using an 'only-keep-debug' symbol file, the original file
+also requires the addition of the `.gnu.debuglink` section (which can be added using `objcopy`)
+
+### Troubles
+
+The Debuginfod protocol is somewhat underspecified regarding what the 2 different callbacks actually return. The protocol itself is quite simple: query an HTTP server with the path `buildid/{.note.gnu.build-id hash}/debuginfo` and `buildid/{.note.gnu.build-id hash}/executable`. A keen reader may note that there's one configuration (split, only-keep-debug) where you need two different files to properly symbolicate, but the API only supports a single debuginfo file. For that scenario, I've chosen to simply treat the `.dwp` file as "debuginfo" and the "only-keep-debug" stripped binary as "executable". This scenario doesn't actually work at all in GDB. It seems more straightforward than trying to extend the protocol.
+
+### Stripped:
+
+- Should ask for symbols from the service; can be registered as 'executable' and
+ they should work!
+
+### Stripped "only-keep-debug":
+
+- Should get them from the debuginfo, not from the executable query
+
+### split-dwarf:
+
+- Should get dwp file from debuginfo
+
+### split-dwarf + stripped:
+
+- Should get dwp from debuginfo, and the unstripped binary from executable

`DEBUGINFOD_URLS` property with a `file://` URL and populate it with the symbol
files we need for testing.
-## Baseline capabilities
-
-Things to test:
-
-- Just for sanity, the `-no-locator` tests validate that lldb works as the test
- expects if the files that Debuginfod _should_ provide are already there.
-- Validate that symbols _aren't_ found without Debuginfod, to ensure they
- weren't cached from previous runs (`-negative` tests).
-- Validate that the Debuginfod symbol locator is providing the expected symbols
- when the debugger doesn't already have them available.
-
-## Symbol "Configurations" to test
-
-There are 2 top level configurations, each of which then get some post-processing.
-- The 'normal' build: a simple binary built with debug information (`-g`)
-- The 'split' build: A binary built with `-gsplit-dwarf` that produces `.dwo` and `.dwp` files
-
-For the normal build there are 2 post-processing steps where Debuginfod may be used.
-- Strip the binary while hosting the full, unstripped binary on a Debuginfod server.
-- Strip the binary and produce a corresponding 'only-keep-debug' version of the binary to host on a Debuginfod server.
-
-For the split build, there are *3* post-processing outcomes where Debuginfod usage makes sense:
-- Stripped binary, hosting the full unstripped binary on a Debuginfod server, along with it's `.dwp` file.
-- Stripped binary, hosting the 'only-keep-debug' version of the binary *and* it's `.dwp` file.
-- Unstripped binary, hosting only the `.dwp` file on the Debuginfod server.
-
-For both normal and split builds, when using an 'only-keep-debug' symbol file, the original file
-also requires the addition of the `.gnu.debuglink` section (which can be added using `objcopy`)
-
-### Troubles
-
-The Debuginfod protocol is somewhat underspecified regarding what the 2 different callbacks actually return. The protocol itself is quite simple: query an HTTP server with the path `buildid/{.note.gnu.build-id hash}/debuginfo` and `buildid/{.note.gnu.build-id hash}/executable`. A keen reader may note that there's one configuration (split, only-keep-debug) where you need two different files to properly symbolicate, but the API only supports a single debuginfo file. For that scenario, I've chosen to simply treat the `.dwp` file as "debuginfo" and the "only-keep-debug" stripped binary as "executable". This scenario doesn't actually work at all in GDB. It seems more straightforward than trying to extend the protocol.
-
-### Stripped:
-
-- Should ask for symbols from the service; can be registered as 'executable' and
- they should work!
-
-### Stripped "only-keep-debug":
-
-- Should get them from the debuginfo, not from the executable query
-
-### split-dwarf:
-
-- Should get dwp file from debuginfo
-
-### split-dwarf + stripped:
-
-- Should get dwp from debuginfo, and the unstripped binary from executable

+## What's being tested
+
+- For assumption validation, the `*-no-locator` tests verify that lldb works as
+ the test expects when files that Debuginfod should provide (`.dwp` files,
+ `.gnu.debuglink`'ed files) are _already_ there.
+- The `*-negative` tests validate that symbols _aren't_ found without
+ Debuginfod, to ensure they haven't been cached from previous runs.
+- The `*-positive` tests check that the Debuginfod symbol locator is providing
+ the expected symbols when the debugger doesn't already have them available.
+
+### Symbol file variations tested
+
+There are 5 variations of symbol data where Debuginfod can provide value:
+
+1. The 'simple-stripped' build variation is a binary built with debug
+ information (`-g`), but stripped for deployment. A Debuginfod service can
+ then host the unstripped binary (as either `executable` or `debuginfo`).
+2. The 'okd-stripped' build variation is a binary build with `-g`, stripped for
+ deployment, where the Debuginfod service is hosting the output of
+ `objcopy --only-keep-debug` (which should also be linked to the stripped file
+ using `--add-gnu-debuglink`). Again, the file could be hosted as either
+ `executable` or `debuginfo`.
+3. The 'simple-split' build variation is a binary built with `-gsplit-dwarf`
+ that produces `.dwo` which are subsequently linked together (using
+ `llvm-dwp`) into a single `.dwp` file. The Debuginfod service should host the
+ `.dwp` file as `debuginfo`.
+4. The 'stripped-split' build variation is a binary built with `-gsplit-dwarf`,
+ then stripped in the same manner as variation #1. For this variation,
+ Debuginfod should host the unstripped binary as `executable` and the `.dwp`
+ file as `debuginfo`.
+5. The 'okd-stripped-split' build variation is the combination of variations 2
+ and 3, where Debuginfod hosts the `.gnu.debuglink`'ed file as `executable`
+ and the `.dwp` again as `debuginfo`.
+
+### Lack of clarity/messy capabilities from Debuginfod
+
+The [debuginfod protocol](https://sourceware.org/elfutils/Debuginfod.html) is
+underspecified for some variations of symbol file deployment. The protocol
+itself is quite simple: query an HTTP server with the path
+`buildid/{.note.gnu.build-id hash}/debuginfo` or
+`buildid/{.note.gnu.build-id hash}/executable` to acquire "symbol data" or "the
+executable". Where there is lack of clarity, I prefer requesting `debuginfo`
+first, then falling back to `executable` (Scenarios #1 & #2). For Scenario #5,
+I've chosen to expect the stripped (i.e. not full) executable, which contains a
+number of sections necessary to correctly symbolicate will be hosted from the
+`executable` API. Depending upon how Debuginfod hosting services choose to
+support `.dwp` paired with stripped files, these assumptions may need to be
+revisited.
+
+I've also chosen to simply treat the `.dwp` file as `debuginfo` and the
+"only-keep-debug" stripped binary as `executable`. This scenario doesn't appear
+to work at all in GDB. Supporting it how I did seems more straight forward than
+trying to extend the protocol. The protocol _does_ support querying for section
+contents by name for a given build ID, but adding support for that in LLDB
+looks...well beyond my current capability (and LLVM's Debuginfod library doesn't
+support it at this writing, anyway).
