+# ESOP '23 Artifact Description
+
+This is the artifact description for our ESOP '23 paper "Clustered Relational Thread-Modular Abstract Interpretation with Local Traces".
+<!-- The artifact is available from Zenodo [here](TODO: Update URL). -->
+
+The artifact is a VirtualBox Image based on Ubuntu 22.04.1. The login is `goblint:goblint`.
+
+<!-- If you are reading these instructions on goblint.readthedocs.io, they might have been updated to match the current version of Goblint.
+When using the artifact, follow the similar instructions it includes. -->
+
+# Getting Started Guide
+
+- Install VirtualBox (e.g. from [virtualbox.org](https://www.virtualbox.org/))
+- Import the VM via `File -> Import Appliance`
+- Start the VM and (if prompted) login as `goblint` with password `goblint`
+- Navigate to the folder `~/analyzer`. All paths are given relative to it.
+- Run the following commands to verify the installation works as intended
+    - `./scripts/esop23-kick-tires.sh`
+        - Internally, this will run a few internal regression tests (the commands that are run are printed)
+        - After the command has run, there should be some messages `No errors :)` as well as some messages `Excellent: ignored check on ... now passing!`)
+
+
+
+
+### Outline of how the code is structured
+Lastly, we give a general outline of how code in the Goblint framework is organized:
+The source code is in the directory `./src`, where the subdirectories are structured as follows:
+
+The most relevant directories are:
+
+- `./src/solvers`: Different fix-point solvers that can be used by Goblint (default is TD3)
+- `./src/domains`: Various generic abstract domains: Sets, Maps, ...
+- `./src/cdomains`: Abstract domains for C programs (e.g. Integers, Addresses, ...)
+- `./src/analyses`: Different analyses supported by Goblint
+- `./src/framework`: The code of the analysis framework
+
+Other, not directly relevant, directories:
+
+- `./src/extract`: Related to extracting Promela models from C code
+- `./src/incremental`: Related to Incremental Analysis
+- `./src/spec`: Related to parsing Specifications for an automata-based analysis of liveness properties
+- `./src/transform`: Specify transformations to run based on the analysis results
+- `./src/util`: Various utility modules
+- `./src/witness`: Related to witness generation

+## Claims in Paragraph "Internal comparison" (p.23)
+
+All these claims derive from Fig. 13 (a) and 13 (b). The data underlying these tables is produced by running:
+
+1. Run the script `../bench/update_bench_traces.rb`. This takes ~25 min (see note below).
+2. Open the results HTML `../bench/bench_result/index.html`.
+
+    - The configurations are named the same as in the paper (with the exception that the `Interval` configuration from the paper is named `box` in the table).
+    - The `size` column in the generated table refers to the total line count (including headers, comments, ...), the
+      `LLoC` can be obtained by looking at the first number in parantheses after the runtime.
+      There are some slight deviations between the numbers in the paper and the artifact, that are due
+      to different versions of library functions caused by different versions of `glibc`.
+    - The number of threads and which are unique is given by the numbers following `T:` in the parenthesis after the runtimes
+
+
+
+### Notes
+* The source code for benchmarks can be found in `../bench/pthread/` and `../bench/svcomp/`.
+* Although it takes ~25 min to run all the benchmarks, the script continually updates the results HTML. Therefore it's possible to observe the first results in the partially-filled table without having to wait for the script to finish.

Subject: [PATCH 0220/1988] Re-export constructors in `src/util/cilType.ml` so
 polymorphic operations are avoided (#956)

This was part of the Goblint practical at TUM in winter 22/23

* Use pattern-matching for monomorphization of equal(x,y) for unop & binop

* Adapt equal() implementation for monomorphization in module Wstring_type & Encoding

* Monomorphize all types that are marked as monomorphizable

* Remove comments to reflect current codebase

* Monomorphise equal and compare functions

* Add back CilType monomorphization comments

Subject: [PATCH 0499/1988] SetDomain.Joined: Do not expose that type t = elt.

Not leaking this abstraction requires changing the signature of may_be_equal to elt -> elt -> bool (from t -> t -> bool).
This commit changes the implementation of the ProjectiveSetPairwiseMeet.meet to iterate also over the elements described by B: SetDomain that is passed.

+# Tests for the support of setjmp/longjmp by Goblint
+
+Some of these tests are technically illegal according to the C standard, as `setjmp` may only appear inside a condition.
+We still have it pulled out here sometimes to allow conveniently inspecting analysis results without having to deal with
+CIL inserted temporaries. GCC also support this without any issues.

Subject: [PATCH 0679/1988] IntDomain code optimizations (#943)

* Update make.sh to also install ocaml with flambda

* Update make.sh for the right flambda switch + update goblint.opam.locked

* Remove eval from opam_setup_flambda

* Update README with flambda installation info

* added lazy evaluation

* Replace frequent get_bool calls with variable lookups

* Memoize config value for ana.int.interval_threshold_widening

* Memoize config value for ana.int.interval_narrow_by_meet and ana.int.def_exc_widen_by_join

* add record to store config variables

* Create configUtil module and use it also in base.ml

* Refactor get_*_config functions to avoid string matching

Also split config value records into multiple smaller records

* Using Sequence Module to perform map

* Remove configUtil module and put everything back in intDomain

* Using Sequence Module to perform map on all methods on base.ml

* Solving some errors of merge conflicts

* Change types of some ana_int_config_values fields to bool option

Use Option.get for value extraction from option types

* Revert "Using Sequence Module to perform map"

This reverts commit 7594b45a7b34bb56aa453f9449db8509ffe0c6a9.

* Revert "Using Sequence Module to perform map on all methods on base.ml"

This reverts commit 619b634ade7d40f7f6657f9dd86f5b43f7425238.

* Revert "Solving some errors of merge conflicts"

This reverts commit abeffdb83f2b8b357f8d850d249784e19022e276.

* Fix indentation in base.ml

* Remove commented out code

* Fix indentation

* Remove usage of deleted ConfigUtil module

* Clean up base.ml from legacy config optimizations

* Replace extract_from_option with Option.get everywhere

* Bring base.ml back to how it was (and fix indentation errors there)

* Fix indentation error in base.ml

* Remove README autoformatting changes

* More README formatting fixes

* Reset record values in intDomain when resetting lazy values

* Optimize with ref variables for config reading in precisionUtil and contextUtil

* Fix indent issues

* Fix FloatDomain accessing IntDomain options at initialization time

This broke int domain activation caching in 7c2455acd1b76c22d07b36856d921523a8c227f3.

* Revert unrelated changes

* Reset PrecisionUtil option caching in server mode

* Fix FloatDomainTest by resetting cached int domain activations

+## Cram Tests
+[Cram-style tests](https://dune.readthedocs.io/en/stable/tests.html#cram-tests) are also used to verify that existing functionality hasn't been broken.
+They check the complete standard output of running the Goblint binary with specified command-line arguments.
+Unlike regular regression tests, cram tests are not limited to testing annotations in C code.
+They can be used to test arbitrary output from Goblint, such as program transformations.
+
+Cram tests are located next to regression tests in `./tests/regression/`.
+
+### Running
+Cram tests are run as part of a complete test run:
+
+* `dune runtest`
+
+This might take a while though. Pass the test directory to `dune` to run only cram tests in a that directory:
+
+* `dune runtest tests/regression/` runs all cram tests.
+* `dune runtest tests/regression/00-sanity` runs all cram tests in `00-sanity`.
+
+To run a single cram test, pass the file name without the `.t` extension and with a leading `@` to `dune build`:
+
+* `dune build @01-assert` runs only `tests/regression/00-sanity/01-assert.t`.
+
+### Writing
+Create new cram tests in a subdirectory of `tests/regression` with the extension `.t`. The basic syntax of a cram test is as follows:
+
+```cram
+Anything not indented by two spaces is a comment.
+  $ goblint <options...> file.c  # This command gets run in a shell.
+  <This is the expected output of running the command.>
+```
+
+The [Dune documentation on file tests](https://dune.readthedocs.io/en/stable/tests.html#file-tests) contains more details.
+
+### Promoting Changes
+When changes cause intentional changes to Goblint's output, cram tests will fail.
+After checking that the changes to Goblint's output shown in failing cram tests are as expected, you need to update those tests.
+Dune can automatically update cram test files, i.e. promote the changes.
+
+First, run the offending test as above. If the new output is correct, accept the changes with `dune promote`.
+
 ## Incremental tests
 The incremental tests are regression tests that are first run with the option `incremental.save` and then again
 incrementally (activating the option `incremental.load`) with some changes to the program or refinements in the

Subject: [PATCH 0803/1988] Replace usage of Queries by ValueDomain and
 ArrayDomain with usages of ValueDomainQueries.

    The goal of this change is to remove dependencies of ValueDomain to Queries, such that Queries can be extended with a query resulting in ValueDomain values.

 The assignment relies on the function `eval`, which is almost there. It just needs you to fix the evaluation of constants! Unless you jumped straight to this line, it should not be too complicated to fix this.
 With this in place, we should have sufficient information to tell Goblint that the assertion does hold.
 
+For more information on the signature of the individual transfer functions, please check out their documentation in the file which they're defined in: [src/framework/analyses.ml](https://github.com/goblint/analyzer/blob/master/src/framework/analyses.ml#LL355C1-L355C17).

 The assignment relies on the function `eval`, which is almost there. It just needs you to fix the evaluation of constants! Unless you jumped straight to this line, it should not be too complicated to fix this.
 With this in place, we should have sufficient information to tell Goblint that the assertion does hold.

Subject: [PATCH 1239/1988] ThreadEscape: also answer whether variable escaped
 in singlethreaded mode, support pthread_setspecific again.

The base analysis relies on variables being considered escaped even in single-threaded mode, when determining which local variables to pass to a callee: Locals possibly reachable via globals need to be considered escaped.

+
+The [Bisect_ppx](https://github.com/aantron/bisect_ppx) tool is used to produce code coverage reports for Goblint.
+The code coverage reports are available on [Coveralls](https://coveralls.io/github/goblint/analyzer).
+
+To run `bisect_ppx` locally:
+
+1. Install `bisect_ppx` with `opam install bisect_ppx`.
+2. [Instrument dune](https://dune.readthedocs.io/en/stable/instrumentation.html#enabling-disabling-instrumentation) with `bisect_ppx`.
+3. Run tests (this will now generate `.coverage` files).
+4. Generate coverage report with `bisect-ppx-report html --coverage-path=tests`.
+5. After that the generated `.coverage` files can be removed with `find . -type f -name '*.coverage' -delete`.
+6. The HTML report can be found in the `_coverage` folder.

Subject: [PATCH 1342/1988] ThreadEscape.threadenter: set local state (i.e.,
 variables secaped in thread) to empty set.

Previous solution that had a non-empty state was required only due to RelationAnalysis that did not pass reachable variables to the created thread in threadenter.

 ### Writing
-* Add parameters to a regression test in the first line: `// PARAM: --set warn.debug true`
-* Annotate lines inside the regression test with comments: `arr[9] = 10; // WARN`
+Regression tests use single-line comments (with `//`) as annotations.
+
+#### First line
+A comment on the first line can contain the following:
+
+| Annotation | Comment |
+| ---------- | ------- |
+| `PARAM: ` <br> (NB! space) | The following command line parameters are added to Goblint for this test. |
+| `SKIP` | The test is skipped (except when run with `./scripts/update_suite.rb group`). |
+| `NOMARSHAL` | Marshaling and unmarshaling of results is not tested on this program. |
+| `TERM` | The expected Goblint result is that the program terminates. |
+| `NONTERM` <br> or `NOTERM` | The expected Goblint result is that the program does not terminate. |
+
+#### End of line
+Comments at the end of other lines indicate the behavior on that line:
+
+| Annotation | Expected Goblint result | Concrete semantics | Checks |
+| ---------- | ----- | ------------- | --- |
+| `SUCCESS` <br> or nothing | Assertion succeeds | Assertion always succeeds | Precision |
+| `FAIL` | Assertion fails | Assertion always fails | Precision |
+| `UNKNOWN!` | Assertion is unknown | Assertion may both <br> succeed or fail | Soundness |
+| `UNKNOWN` | Assertion is unknown | — | Intended imprecision |
+| `TODO` <br> or `SKIP` | Assertion is unknown <br> or succeeds | Assertion always succeeds | Precision improvement |
+| `NORACE` | No race warning | No data race | Precision |
+| `RACE!` | Race warning | Data race is possible | Soundness |
+| `RACE` | Race warning | — | Intended imprecision |
+| `NODEADLOCK` | No deadlock warning | No deadlock | Precision |
+| `DEADLOCK` | Deadlock warning | Deadlock is possible | Soundness |
+| `NOWARN` | No warning | — | Precision |
+| `WARN` | Some warning | — | Soundness |
+
+#### Other
+Other useful constructs are the following:
+
+| Code with annotation | Comment |
+| -------------------- | ------- |
+| `__goblint_check(1); // reachable` | Checks that the line is reachable according <br> to Goblint results (soundness). |
+| `__goblint_check(0); // NOWARN (unreachable)` | Checks that the line is unreachable (precision). |
 
 ## Cram Tests
 [Cram-style tests](https://dune.readthedocs.io/en/stable/tests.html#cram-tests) are also used to verify that existing functionality hasn't been broken.

Subject: [PATCH 1354/1988] Try to make cram test output deterministic

Currently the order of messages may depend on varinfo IDs in hashtables or whatnot.
Since these differ on Linux and OSX, so does the message order.

Subject: [PATCH 1422/1988] Make join/smart_join/widen/smart_widen preserve
 equal inputs.

Issue #1091 was caused by the join/widen (and corresponding smart operations)
for unions in ValueDomain not return the same element.
The optimization in PMap that returns the unchanged map when two
physically identical maps were joined was thus yielding a different value in the
from-scratch run compared to the incremental run.

Subject: [PATCH 1427/1988] Add ValueDomain.try_meet, meet that may fail for
 unions with different active fields, use it in BaseInvariant.

The refinement by BaseInvariant to handle branching used VD.meet, which
caused issue #1105, due to the behavior of UnionDomain.meet:
The meet of unions with different active fields can result in a bottom value.
This led to e.g. spuriously dead code.

This commit adds a function try_meet to the valueDomain, the union domain,
and those domains that may contain a union domain element: structs, arrays, blobs.
The function try_meet in the union domain throws an exception in the
case the fields of the unions for which a meet was tried did not coincide.
In case this exception occurs, the BaseInvariant does not perform
refinement.

Subject: [PATCH 1446/1988] UnionDomain.meet: Raise Uncomparable exception when
 active fields do not match.

Raise an Lattice.Uncomparable exception when the active fields of the unions that the meet is applied to, do not match. Catch Uncomparable exception in
BaseInvarian, and do not do refinement in case the exception is thrown during the VD.meet.

Subject: [PATCH 1458/1988] Make UnionDomain.Simple.meet explicit to enforce
 order in which operations are performed.

The implementation of Lattice.Prod.meet does not enforce that the meet of the first element in the tuple is performed first.
This is needed however, to ensure that a Lattice.Uncomparable exception is thrown when the fields do not match, and avoids a IncomopatibleIkind exception.

+    {{!Access.MemoRoot} Root} can be:
+    + variable, if access is to known global variable or alloc-variable;
+    + type, if access is to unknown pointer.
+
+    Accesses are (now) collected to sets for each corresponding memo,
+    after points-to sets are resolved, during postsolving.
+
+    Race checking is performed per-memo,
+    except must additionally account for accesses to other memos (see diagram below):
+    + access to [s.f] can race with access to a prefix like [s], which writes an entire struct at once;
+    + access to [s.f] can race with type-based access like [(struct S).f];
+    + access to [(struct S).f] can race with type-based access to a suffix like [(int)].
+    + access to [(struct T).s.f] can race with type-based access like [(struct S)], which is a combination of the above.
+
+    These are accounted for lazily (unlike in the past).
+
+    Prefixes (a.k.a. inner distribution) are handled using a trie data structure enriched with lattice properties.
+    Race checking starts at the root and passes accesses to ancestor nodes down to children.
+
+    Type suffixes (a.k.a. outer distribution) are handled by computing successive immediate type suffixes transitively
+    and accessing corresponding offsets from corresponding root tries in the global invariant.
+
+    Type suffix prefixes (for the combination of the two) are handled by passing type suffix accesses down when traversing the prefix trie.
+
+    Race checking happens at each trie node with the above three access sets at hand using {!Access.group_may_race}.
+    All necessary combinations between the four classes are handled, but unnecessary repeated work is carefully avoided.
+    E.g. accesses which are pairwise checked at some prefix are not re-checked pairwise at a node.
+    Thus, races (with prefixes or type suffixes) are reported for most precise memos with actual accesses:
+    at the longest prefix and longest type suffix.
+
+    Additionally, accesses between prefix and type suffix intersecting at a node are checked.
+    These races are reported at the unique memo at the intersection of the prefix and the type suffix.
+    This requires an implementation hack to still eagerly do outer distribution, but only of empty access sets.
+    It ensures that corresponding trie nodes exist for traversal later. *)
+
+(** Example structure of related memos for race checking:
+    {v
+     (int)   (S)     (T)
+        \   /   \   /   \
+          f       s       t
+            \   /   \   /
+              f       s
+                \   /
+                  f
+    v}
+    where:
+    - [(int)] is a type-based memo root for the primitive [int] type;
+    - [(S)] and [(T)] are short for [(struct S)] and [(struct T)], which are type-based memo roots;
+    - [f] is a field of [S] and [s] is a field of [T];
+    - [t] is a global variable of type [T].
+    - prefix relations are indicated by [/];
+    - type suffix relations are indicated by [\ ].
+
+    Prefix races:
+    - Race between [t.s.f] and [t.s] is checked/reported at [t.s.f].
+    - Race between [t.s.f] and [t] is checked/reported at [t.s.f].
+    - Race between [t.s] and [t] is checked/reported at [t.s].
+    - Race between [t] and [t] is checked/reported at [t].
+    - Race between [(S).f] and [(S)] is checked/reported at [(S).f].
+
+    Type suffix races:
+    - Race between [t.s.f] and [(T).s.f] is checked/reported at [t.s.f].
+    - Race between [t.s.f] and [(S).f] is checked/reported at [t.s.f].
+    - Race between [t.s.f] and [(int)] is checked/reported at [t.s.f].
+    - Race between [(S).f] and [(int)] is checked/reported at [(S).f].
+
+    Type suffix prefix races:
+    - Race between [t.s.f] and [(T).s] is checked/reported at [t.s.f].
+    - Race between [t.s.f] and [(T)] is checked/reported at [t.s.f].
+    - Race between [t.s.f] and [(S)] is checked/reported at [t.s.f].
+    - Race between [(T).s.f] and [(S)] is checked/reported at [(T).s.f].
+
+    Prefix-type suffix races:
+    - Race between [(T).s] and [(S).f] is checked/reported at [(T).s.f].
+    - Race between [t] and [(S).f] is checked/reported at [t.s.f]. *)

 # Benchmarking
+The following best practices should be followed when benchmarking Goblint.
+This is to ensure valid, reproducible and representative benchmarking results.
 
-To achieve reproducible builds and the best performance for benchmarking, it is recommended to compile Goblint using the `release` option:
+# External benchmarking
+External users should choose the version of Goblint to evaluate or benchmark as follows:
+
+1. Use the newest version release.
+
+    The version from git `master` branch or any other intermediate git commit come without any guarantees.
+    They are bleeding-edge and haven't gone through validation like the version releases.
+
+    SV-COMP releases are highly preferable since they've gone through rigorous validation in SV-COMP.
+
+2. Download the corresponding version from a Zenodo artifact or by checking out the respective git tag. **Do not install directly from opam repository!**
+
+    Goblint pins optimized versions of some dependencies which cannot be done on the opam repository releases.
+    Thus, using the latter would yield unrepresentative results.
+
+    Zenodo artifacts come with DOIs, which make them ideal for citation.
+
+3. Use OCaml 4.14. **Do not use OCaml 5!**
+
+    OCaml 5 has significant performance regressions, which yield unrepresentative benchmarking results.
+    Goblint's `make setup` installs the correct OCaml version into a new opam switch.
+
+# Release build
+To achieve the best performance for benchmarking, Goblint should be compiled using the `release` option:
 
 ```sh
 make release

Subject: [PATCH 1751/1988] fix: copying of files to GobView in projects with
 subdirectories (#1143)

* fix: macos command line file

* fix: special paths for macos and non-english languages

special paths are os and language dependant.
ex. <command-line> -> <command line> for macos

* fix: prevent recursive directory copies when using gobview

* fix: correct counter for gobview files
Counter for unique file names was broken by skipping directory entries

* fix: remove unnecessary recursive copying
