1.7.0-dev.110 | 2023-02-03 15:57:39 +0100

  * https://github.com/zeek/spicy-plugin/issues/134: Search
    `HILTI_CXX_INCLUDE_DIRS` paths before default include paths.
    (Robin Sommer, Corelight)

  * Support Zeek-style documentation strings in Spicy source code. (Robin Sommer, Corelight)

    This adds support for extracting and retaining Zeek-style
    documentation strings (`##`, `##!`) inside Spicy source code to any
    top-level AST nodes where it's appropriate: if they are prefixed with
    a block of such comments, that information is retained along with the
    node for later access.

    The code printer (`-p`) learns to emit doc strings coming with the
    nodes it's printing out.

1.7.0-dev.95 | 2023-01-27 12:00:41 +0100

  * Streamline runtime exception hierarchy. (Robin Sommer, Corelight)

    We were inconsistent in the structure of exceptions that could
    happen during runtime, making it hard for host applications for
    consistently handle trouble. We tweak this, as follows:

        - We now only have two general subcategories of exceptions under the
          top-level `hilti::rt::Exception`:

            - `RuntimeError`: non-fatal errors that mean a host
              applications cannot complete the current line of processing,
              but can otherwise continue. This is the main exception that
              host applications should catch, and then proceed
              appropriately.

            - `UsageError`: fatal errors that indicate something about
              using the runtime environment was fundamentally wrong, and a
              host application should abort.

        - Almost all other exceptions are now derived from `RuntimeError`,
          including Spicy's `ParseError` and `RecoverableFailure`, so that
          they can treated consistently.

1.7.0-dev.93 | 2023-01-27 11:57:58 +0100

  * Search user module paths before system paths. (Robin Sommer, Corelight)

    With, e.g., `spicyz -L /x/y/z`, we used to append the given module
    path to the internal system paths, so that it was searched last. This
    change turns around the priority to search `/x/y/x` first, before the
    internal ones. That seems both more useful and more intuitive.

  * Provide ability for host applications to initiate runtime's
    module-pre-init phase manually. (Robin Sommer, Corelight)

1.7.0-dev.89 | 2023-01-27 11:44:31 +0100

  * Add DPD-style `spicy::accept_input()` and `spicy::decline_input()`. (Robin Sommer, Corelight)

    This generalizes the accepting/decline input from being a Zeek thing to
    being part of Spicy. Any Spicy grammar can call these functions as to
    tell its host application if it recognizes the input format. The host
    application can (but doesn't have to) install callbacks to receive
    that information and react appropriately. For example, the Zeek
    plugin will just forward it to Zeek's standard DPD hooks.

    For testing, `spicy-driver` gets a new option `--require-accept`
    that lets it exit with success only if `spicy::accept()` has
    been called, and  `spicy::decline_input()` hasn't.

    Note: The naming of the two functions is avoid conflicts with the
    existing notion of synchronization's confirm/reject.

  * Add a global configuration object to the Spicy runtime. (Robin Sommer, Corelight)

    We didn't have a mechanism yet for a host application to configure the
    runtime library's behavior. This follows what we do on the HILTI-side
    to provide that capability.

1.7.0-dev.86 | 2023-01-27 11:35:35 +0100

  * Add driver option to output full set of generated C++ files. (Robin Sommer, Corelight)

    `-x <prefix>` now writes out all generated C++ code as
    `<prefix>_*.cc`, also setting the internal C++ namespace prefix to
    `<prefix>`.

  * Add test for sink's paying attention to linker scopes with static C++ code. (Robin Sommer, Corelight)

  * Make test helper scripts `cxx-*` usable with Spicy code as well. (Robin Sommer, Corelight)

  * Provide new HILTI keyword `$scope` to access linker scope. (Robin Sommer, Corelight)

  * Prefix the linker scope with the internal CXX namespace. (Robin Sommer, Corelight)

  * Fix a couple of places hardcoding the internal C++ namespace prefix. (Robin Sommer, Corelight)

  * Prefix the linker symbols for versioning with C++ namespace. (Robin Sommer, Corelight)

1.7.0-dev.78 | 2023-01-27 11:16:01 +0100

  * GH-1123: Support arbitrary expression as argument to type
    constructors, such as `interval(...)`. (Robin Sommer, Corelight)

    So far we used constructor expressions like `interval(...)` to create
    *constants* of the given type, and for that we required that the
    argument was a single atomic value. The result was that these
    constructor expressions were really more like literals for the
    corresponding types than "normal" expressions. While that's useful
    internally, it's confusing to the user. This commits changes that
    to support arbitrary expressions as arguments.

    To make this change without loosing a way to create actual constants
    (which we need at some places), we implement this in two stages: the
    parser initially turns such `interval(...)` expressions into call
    operators[1] that the types now define for each desired constructor. We
    then extend the normalizer with a new constants folding pass that
    turns the call expressions into constants if possible.

    The new constant folder remains limited to the cases we need for
    this use case, but we'll be able to expand that later to  more
    general folding.

  * Fix bug in cast from `real` to `interval`. (Robin Sommer, Corelight)

  * Add anchors to FAQ items in docs [skip CI]. (Benjamin Bannier, Corelight)

1.7.0-dev.53 | 2023-01-25 09:39:02 +0100

  * Add stringification to UnitContext. (Benjamin Bannier, Corelight)

1.7.0-dev.51 | 2023-01-25 09:36:56 +0100

  * Remove potential race during JIT when using `HILTI_CXX_COMPILER_LAUNCHER`. (Benjamin Bannier, Corelight)

1.7.0-dev.49 | 2023-01-20 10:41:46 +0100

  * GH-1349: Fix incremental regexp matching for potentially empty results. (Robin Sommer, Corelight)

    When feeding data incrementally into the regexp matcher, we could run
    into an assert trying to ensure that the end of a match wasn't in the
    previous chunk already. Turns out, however, that *is* possible with
    empty matches that are determined only later (and maybe it's possible
    in other cases, too). To fix this, we need to account for potentially
    backtracking into data from a previous round. This could be a bit
    surprising to callers of the `advance()` method, but should
    work as long as they aren't trimming the stream in between (which in
    our use cases shouldn't be the case).

    Closes #1349.

  * Install full nlohmann JSON header as well. (Benjamin Bannier, Corelight)

    We previously would only install the nlohmann header with forward
    declaration while in `hilti/rt/json.h` we include the full header. With
    that it was impossible to include this header in user code.

    This patch makes sure we install the full header as well.

1.7.0-dev.45 | 2023-01-19 09:46:14 +0100

  * Remove dead code. (Benjamin Bannier, Corelight)

  * Remove performance pessimization introduced in `84fb4f21f494`. (Benjamin Bannier, Corelight)

    When exposing this function directly we made the argument always
    evaluate. This now causes us to compute strings for logging even if they
    are never emitted.

    Undo this change as it is actually not needed for the cleanup it was
    initially intended for.

  * GH-1345: Fix pathological performance for `_haveEod` on highly chunked streams. (Benjamin Bannier, Corelight)

    This function was identified as a performance bottleneck when parsing
    `bytes` with a huge size from a stream with many chunks. The reason it
    performed so poorly was due to its use of `unsafeEnd`: since `unsafeEnd`
    creates an unsafe iterator from `end()` it always needs to compute the
    chunk the safe iterator pointed to; if the stream contains many chunks
    this causes the seen poor performance.

    Since we only access `offset` use safe iterators instead. This makes it
    much cheaper to call this function so we can safely use it during
    parsing.

    Since this change only affects performance we do not add a test case.
    For a benchmark see #1345.

    Closes #1345.

1.6.0-dev.48 | 2022-08-18 16:30:14 +0200

  * GH-1251: When decoding bytes into a string using a given character
    set, allow caller to control error handling. (Robin Sommer,
    Corelight)

    All methods taking a charset parameters now take an additional
    enum selecting 1 of 3 possible error handling strategies in case a
    character can't be decoded/represented: `STRICT` throws an error,
    `IGNORE` skips the problematic character and proceeds with the
    next, and `REPLACE` replaces the problematic character with a safe
    substitute. `REPLACE` is the default everywhere now, so that by
    default no errors are triggered.

    This comes with an additional functional change for the ASCII
    encoding: we now consistently sanitize characters that ASCII can't
    represent when in `REPLACE`/`IGNORE` modes (and, hence, by
    default), and trigger errors in `STRICT` mode. Previously, we'd
    sometimes let them through, and never triggered any errors. This
    also fixes a bug with the ASCII encoding sometimes turning a
    non-printable character into multiple repeated substitutes.

  * GH-1187: Fix support for having multiple source modules of the
    same name. (Robin Sommer, Corelight)

    There was an underlying assumption in much of the code that a module
    name would be globally unique, meaning it could be used as index into
    maps and as seeds for C++ identifiers. However, while that's often the
    case, the `import ... from ...` syntax allow pulling in multiple
    modules all having the same name.
    This change fixes that to track a module's "scope" (i.e., the part
    after `from ...`) more thoroughly across various pieces..

  * GH-1072: Disallow enum declarations with non-unique values. (Benjamin Bannier, Corelight)

    It is unclear what code should be generated when requested to convert an
    integer value to the following enum:

        type E = enum {
            A = 1,
            B = 2,
            C = 1,
        };

    For `1` we could produce either `E::A` or `E::C` here.

    Instead of allowing that ambiguity we disallow enums with non-unique
    values with this patch.

    Closes #1072.

1.4.0-dev.148 | 2022-01-13 08:17:53 +0100

  * Use libc++ instead of libstdc++ on debian-9. (Benjamin Bannier, Corelight)

    In libstdc++-10-dev-10.3.0-13 Debian includes the upstream GCC patch
    2b2d97fc545 without also including at least 4f032929ac9. This leads to
    errors e.g., triggered from nlohmann/json were `&noexcept` attributes
    are used inconsistently.

    Since debian-9 should only receive security updates at this point it is
    unclear to me how such a feature change ended up being backported. At
    this point it is not clear to me whether it will see another patch
    release. For these reasons we switch the build over to use libc++
    instead which comes from the LLVM repo and should still receive reliable
    updates.

1.2.0-dev.17 | 2021-05-31 12:36:27 +0200

  * Add tests for global optimizations. (Benjamin Bannier, Corelight)

  * Add optimizer pass removing unimplemented member functions.

    This patch introduces a global pass triggered after all individual input
    ASTs have been finalized, but before we generate any C++ code. We then
    strip out any unimplemented member functions (typically Spicy hooks),
    both their definitions as well as their uses.

    In order to correctly handle previously generated C++ files which might
    have been generated with different optimization settings, we disallow
    optimizations if we detect that a C++ input file was generated by us. (Benjamin Bannier, Corelight)

  * Fix computation of unset locations. (Benjamin Bannier, Corelight)

  * Detect presence of sink hooks at compile time.

    Sink hooks are by default generated for any `public` unit. With the
    introduction of an optimizer pass to remove unused hooks we might now
    remove them and need to detect their presence when e.g., registering a
    parser.

    This patch moves from these instances from branching on whether a unit
    is `public` to directly detecting the presence of the hooks. (Benjamin Bannier, Corelight)

  * Introduce dedicated codegen step in Driver. (Benjamin Bannier, Corelight)

  * Fix test to correctly log output.

    We previously logged the output of this test to a file we never
    examined. (Benjamin Bannier, Corelight)

  * Autoupdate pre-commit hooks. (Benjamin Bannier, Corelight)

1.2.0-dev.9 | 2021-05-31 12:11:30 +0200

1.1.0-dev.85 | 2021-05-11 16:19:12 +0200

  * Add functions for CRC32 computation to Spicy library. (Robin
    Sommer, Corelight)

  * Add a find() method to units to search within their block of
    input. (Robin Sommer, Corelight)

  * Add support for searching a stream view backward for bytes. (Robin Sommer, Corelight)

  * Optimize implementation of Spicy's library filters a little bit. (Robin Sommer, Corelight)

  * Fix missing update to input position before running `%done` hook. (Robin Sommer, Corelight)

  * Add support for `&eod` to `void` fields. This skips all data until
    the end of the current input is encountered. (Robin Sommer,
    Corelight)

  * Add support for `&until` to `void` fields.

      Example:

        ```
        public type Foo = unit {
          : void &until=b"XYZ";
}
        ```

    This skips all data until `XYZ` is encountered. Similar to the
    `&until` attribute that `bytes` provides, the deliminator is
    extracted from the stream before continuing. (Robin Sommer,
    Corelight)

  * Add support for `&chunked` when parsing bytes data with `&until`
    or `&until_including`. (Robin Sommer, Corelight)

    (Robin Sommer, Corelight)

1.1.0-dev.37 | 2021-04-24 09:28:04 +0200

  * Add new Spicy runtime function `spicy::zlib_init(window_bits)`
    that initializes a `ZlibStream` for decompression with the given
    window size argument. See the zlib documentation at
    https://www.zlib.net/manual.html for more on the argument. (Robin

0.4.0-1632 | 2021-03-23 20:01:10 +0100

  * GH-853: Fix extraction of integer bits when all bits requested.

    When calculating the extraction mask, we previously would shift an
    integer beyond its width which triggers UB. With this patch we now
    correctly detect such cases and directly return the input.

  * GH-450: Add `!in` to HILTI and Spicy parser.

0.4.0-1614 | 2021-03-18 12:27:45 +0000

    Bannier, Corelight)

0.4.0-1551 | 2021-03-04 09:52:00 +0100

  * GH-570: Explicitly reject comparisons of units with `==` and `!=`.

    Comparisons with `==` and `!=` are not explicitly modelled in Spicy or
    HILTI which means that while we resolved the types of the LHS and RHS,
    during codegen we just emit a `==` or `!=` which needs to be resolved.

    While most runtime types should support these operators, units do not,
    so that previously users would see a compiler error during JIT when
    comparing values of unit type with `==` or `!=`. This patch adds a
    validator which explicitly rejects such comparisons.

0.4.0-1547 | 2021-03-03 09:13:25 +0100

  * GH-798: Prevent conversions of some integers to doubles on the Zeek interface.

    While we previously provided specialized conversion functions to Zeek
    `ValPtr` these were not used for plain integer types like e.g.,
    `std::size_t` or `unsigned long`. Instead C++ overload resolution
    preferred to instead convert the integers to `double` (for which we
    provide a specialization) and them being emitted with `TYPE_DOUBLE`.

    This patch introduces an additional specialization which converts such
    naked integers to safe integers and then converts them to Zeek.

0.4.0-1545 | 2021-03-03 09:12:29 +0100

  * GH-733: Validate that `foreach` is only used with container fields.

0.4.0-1543 | 2021-03-02 07:37:21 +0000

  * Move protocol analyzers into submodule. This moves all the
    protocol analyzers into its own submodule `spicy-analyzers`, which
    doubles as a Zeek package installing them. There's a new
    `spicy-analyzers` target to pre-compile those analyzers for Zeek.
    (Robin Sommer, Corelight)

  * Zeek plugin updates (Robin Sommer, Corelight)

      - Move registration of Zeek components to load time.
      - Work around problem in Zeek's analyzer API.

   * Update pathfind to fix problem on Alpine. (Robin Sommer,
     Corelight)

0.4.0-1541 | 2021-03-02 07:22:26 +0000

  * Add support for `@if/@else/@endif` in Spicy scripts, similar to
    what EVT files already provided. This currently supports testing
    for three constants at compile time: `SPICY_VERSION`,
    `ZEEK_VERSION`, `HAVE_ZEEK`. See the documentation for more.
    (Robin Sommer, Corelight)

  * Increase CI memory for platforms that are prone to OOMing. (Robin
    Sommer, Corelight)

0.4.0-1533 | 2021-03-02 07:21:39 +0000

  * Fix strftime unit test: increase portability of localtime_r()
    usage (Christian Kreibich, Corelight)

0.4.0-1531 | 2021-03-01 11:40:35 +0100

  * GH-768: Add language support to explicitly trigger a parse error.

    This patch adds a Spicy `throw` statement of the form

        throw EXPR;

    which when hit triggers a parse error with the message `EXPR`.

0.4.0-1529 | 2021-03-01 11:06:22 +0100

  * GH-767: Add &max-size attribute.

    This patch adds a &max-size field and unit attribute. The attribute
    allows setting up a maximum number of bytes a parse step should consume.

    It is conceptually similar to the existing &size attribute but differs
    from it in that an error is raised only if more than the specified bytes
    were extracted (&size enforces that exactly the specified number of
    bytes is extracted).

    &max-size cannot be used together with &size.

0.4.0-1521 | 2021-02-26 08:50:04 +0000

  * GH-791: Bring back validation of field parseability. (Robin
    Sommer, Corelight)

  * GH-762: Add support for Zeek file analyzer replacement (requires
    Zeek 4.1+). (Jon Siwek, Corelight)

0.4.0-1513 | 2021-02-25 14:49:43 +0000

  * GH-771: Improve docs for vector &until parsing. (Jon Siwek,
    Corelight)

0.4.0-1511 | 2021-02-24 19:34:56 +0000

  * GH-694: Support unit-level `&convert` attribute. (Robin Sommer,
    Corelight)

    This attribute transforms a unit instance after parsing by returning the
    result of a custom expression to parent units, instead of the instance
    itself.

    Example:

        type Data = unit {
    data:
        bytes& size = 2;
    }
    &convert = self.data.to_int();

public
    type Foo = unit {
    numbers:
        Data[];
        on % done { print self.numbers; }
    };

#printf 12345678 | spicy - driver unit - convert.spicy
        [12, 34, 56, 78]

    Note how the `Data` sub-elements have been turned into integers. Without
    the new `&convert` attribute, the output would have looked like this:

        [[$data=b"12"], [$data=b"34"], [$data=b"56"], [$data=b"78"]]

  * GH-736: Fix bug that could cause hooks for anonymous fields to not
    execute. (Robin Sommer, Corelight)

  * Support parsing of nested fields. (Robin Sommer, Corelight)

    The new test case shows a number of examples that are now supported:

        public type Test = unit {
        i1:
            (bytes& size = 5);
        i1b:
            (bytes& size = 5 & convert = 42);
        i2:
            (int8[3]);
        i3:
            (int8[2])[3];
        i4:
            (int8[]& until = ($$ == 'X'))[]& until = ($$ == vector(55, 56));
        i5:
            (FooImpl);
        i6:
            (FooImpl[2]);
        i7:
            (FooImpl[2])[3];
        i8:
            (FooImpl& convert = 42);
        i9:
            (FooImpl& convert = 42)& convert = $$ * 2;
        i10a:
            (bytes& size = 5 & convert = $$.to_int());
        i10b:
            (Bytes& size = 5 & convert = $$.to_int());
        i10c:
            (FooImpl& convert = $$.data.to_int());
        i11:
            (FooImpl& convert = $$.data.to_int())& convert = $$ * 2;
        i12:
            (FooImpl& convert = $$.data.to_int())[2];
        i13: (FooImpl &convert=$$.data.to_int())[2] &convert=[3 * xyz for xyz in $$];
        }

    While the expectation isn't really that people would write this, this
    puts the infrastructure in place to support functionality that needs
    more complex field structures. (Robin Sommer, Corelight)

  * GH-770: Evaluate the AND of all field `requires` clauses.

    We already did this correctly for units by previously only evaluated the
    first `&requires` clause for fields.

  * Tweak auto-discover of *.hlto files in Zeek plugin. (Robin Sommer, Corelight)

    The plugin now scans for *.hlto files at startup at two locations by
    default:

        1. A directory "modules/" inside the plugins top-level directory.

        2. Zeek's default plugin directory.

    Both of these places are searched *recursively*, similar to how Zeek
    looks for binary plugins.

    Alternatively, one can override both of these by setting an environment
    variable `SPICY_MODULE_PATH` to a colon-separated list of directories,
    which will then be searched recursively *instead* of the default
    locations.

  * Extend spicy-config with a couple more Zeek-related options, and
    tweak some existing option names. (Robin Sommer, Corelight)

  * GH-744: Fix out-of-bounds access in tuple index type resolution.

    This code was previously indexing into a vector beyond the end when
    determining the type of a tuple index operation. We now
    return an unknown type here here so that we can reject the operation
    during later validation.

  * GH-709: Fix codegen's result type of unit.offset(). (Robin Sommer,
    Corelight)

  * GH-709: Add description of enum use to Zeek plugin documentation.
    (Robin Sommer, Corelight)

  * Fix bug with custom enum types not being available in time for
    Zeek scripts. Turns out that for precompiled Zeek analyzers it
    didn't work to automatically make the Spicy-side enum types
    available to Zeek scripts because of a timing issue. (Robin
    Sommer, Corelight)

    Closes #731. (Benjamin Bannier, Corelight)

0.4.0-1428 | 2021-02-16 16:04:42 +0000

  * GH-690: Add `%finally` hook to Spicy units.

    ``on %finally  {
        ...
    }``
        Executes once unit parsing has completed in any way. This hook is
        most useful to modify global state that needs to be updated no
        matter the success of the parsing process. Once `%init` triggers, this
        hook is guaranteed to eventually execute as well. It will run
        *after* either ``%done`` or ``%error``, respectively. (If a new
        error occurs during execution of ``%finally``, that will not
        trigger the unit's ``%error`` hook.)

  * Generalize %error to catch all exceptions. So far it was catching
    only HILTI-side errors. Now we do general catch-all so have a
    reliably hook for error handling no matter what's the cause.
    (Robin Sommer, Corelight)

  * Support finalizers in HILTI structs. There's a now new magic hook
    `~finally` that will run automatically when a struct instance gets
    destroyed. (Robin Sommer, Corelight)

  * Fix double normalization in ID strings. (Robin Sommer, Corelight)

0.4.0-1422 | 2021-02-16 10:49:34 +0000

  * GH-696: Add support for shared unit contexts with lifetime
    determined by host application. (Robin Sommer, Corelight)

    This introduces a new unit property for public unit types:

        %context = <type>;

    The unit's new `context()` method will then return a value of type
    `<type>&` (i.e, a reference to an instance of the given type). This will
    be initialized with a reference to a default-constructed instance of the
    type.

    What makes this special is that the host application can determine how a
    context instance is being shared across different parsers: it can (1)
    let multiples units link their context to the same instance, and (2)
    retain a context instance beyond any specific unit's lifetime.

    We use this new mechanism to provide contexts with connection-level
    semantics: the Zeek plugin, and also spicy-driver's batch mode, will
    create a single context instance that the two originator-side and
    responder-side units will share (they must declare matching contexts
    for that to work). The object will live until the connections gets
    torn down (also meaning it'll be reused across the per-packet parsers
    for UDP).

    See the documentation for examples.

  * Add `<vector>.pop_back()`. (Robin Sommer, Corelight)

  * Support assignment to tuple elements. (Robin Sommer, Corelight)

  * Extend the spicy-driver batch format to be able to express
    bi-direction connection semantics. This increases the batch format
    version to v2. (Robin Sommer, Corelight)

  * Add new variant of external function linkage to HILTI that skips
    the resumable wrapping. (Robin Sommer, Corelight)

0.4.0-1358 | 2021-02-01 10:40:23 +0100

  * GH-701: Make offsets usable from unit field attributes.

    We previously updated parse positions when entering productions. This is
    insufficient as the evaluation of attributes might already access the
    position via `self.offset()`.

    With this patch we now only update the parse position before we start
    parsing of a field.

    Closes #701. (Benjamin Bannier, Corelight)

  * Use ubuntu-20 as base for published Docker image. (Benjamin Bannier, Corelight)

  * Set PATH and ZEEK_PLUGIN_PATH for ubuntu Docker images. (Benjamin Bannier, Corelight)

  * Validate Zeek installation for Docker CI tasks. (Benjamin Bannier, Corelight)

  * Fix Docker images for possible lib libdir.

    This patch fixes the `ZEEK_PLUGIN_PATH` set in Docker images so Zeek can
    find plugins even if the Spicy installation was performed with a libdir
    named `lib` instead of `lib64`. (Benjamin Bannier, Corelight)


0.4.0-1346 | 2021-01-29 08:26:26 +0000

  * GH-685: Allow to define a minimum Spicy version that a module
    requires. Adding `%spicy-version = "1.0";` to a module now lets it
    require to compile with a Spicy of at least that version. The
    version can be specified as either `x.y` or `x.y.z`. (Robin
    Sommer, Corelight)

  * GH-688: Add functions `zeek::uid()` and `zeek::fuid()` to access
    UIDs and FUIDs, respectively. (Robin Sommer, Corelight)

  * GH-689: Allow to pass a MIME type to `file_new()` when beginning
    file analysis. (Johanna Amann, Corelight)

        type Bar = unit(n: uint64) {
x:
    bytes& eod;
        } &size=n;

    Parsing less than `n` bytes is an error. (Robin Sommer, Corelight)

0.4.0-1255 | 2021-01-18 08:45:26 +0000

  * Port JIT to use host C++ compiler instead of libclang/libllvm.
    (Robin Sommer, Benjamin Bannier; Corelight).

    This completely removes the dependency on an existing clang
    installation. Instead, JIT now requires only a C++17 host
    compiler. Internally, this comes with a substantial refactor of
    the JIT components.

    This changes also includes the following additional pieces:

        - We pull in `https://github.com/DaanDeMeyer/reproc` as a
          submodule for spawning the host compiler.

        - The environment variable `HILTI_CXX` overrides the
          executable to use as the C++ compiler during JIT. It won't
          work to switch in a completely different compiler that way
          (because we'd continue to make some assumptions based on the
          default compiler), but it allows to provide an additional
          wrapper around the default compiler.

        - We remove the distinction between building the toolchain
          with/without JIT. We now always assume we have the JIT
          capbility available, but will fail gracefully when unable to
          use the host compiler.

        - JIT compilation captures & reports C++ error output.

  * Extend `{hilti,spicy}-config` with options `--cxx-flags-hlto`/`--cxx-flags-hlto`

0.4.0-1227 | 2021-01-13 07:41:35 +0000

  * Re-implement the runtime's fiber (co-routine) code. (Benjamin
    Bannier, Robin Sommer; Corelight).

    This should be mostly transparent to users, but internally the
    main pieces are:

    - GH-561: Switch from libtask to new 3rd-party fiber library
      (https://github.com/simonfxr/fiber.git).

    - GH-561: Support "shared stack" mode for fibers where the runtime
      only allocates a single stack that's used by all fibers, vs.
      individual per-fiber stacks. This comes with a slight
      performance penalty for context switching, but substantially
      improves memory usage (and, in turn, performance with lots of
      concurrent fibers). The shared stack is used by default now.
      There's also new benchmark hilti-rt-fiber-benchmark to profile
      performance.

    - GH-460: Add runtime checks for risk of stack overflow. When the
      HILTI codegen creates a function, it now always inserts a stack
      check at the beginning that ensures that a minimal amount of
      stack space remains available. If it is not, we abort with a
      runtime exception. This gives us well-defined behavior if call
      stacks go too deep. The minimum amount of stack space is
      configurable through a global option.

    Along with this comes large refactor of the runtime's fiber code.

  * Fix Linux' --ldflags for pthread. (Robin Sommer, Corelight)

  * Make hilti::rt::isInitialized() save to be used when no global
    state is available. (Robin Sommer, Corelight)

  * When running the CI container through the Makefile, use local
    user's UID/GID. (Robin Sommer, Corelight)

  * Adding missing call to rt::done() to default main(). (Robin
    Sommer, Corelight)

  * Fix CMake logic for hilti-rt. (Robin Sommer, Corelight)

  * Enable leak checking by default in ASAN builds. ASAN itself
    enables it only on Linux by default. (Robin Sommer, Corelight)

  * Let autogen-version find VERSION independent of current directory.

0.4.0-1148 | 2021-01-04 08:10:25 +0000

  * Overhauling regexp matching semantics.

    We were inconsistent in how regular expressions (1) handled being anchored
    vs not, and (2) allowed to retrieve the matching data. We fix this as
    follows:

    - We rename the regexp methods for more consistency: `match` now means
      "matching is anchored at the beginning of the data", and `find` means
      we find matches anywhere in the data. This leads to the following
      renames:

        * <regexp>.find -> <regexp>.match
        * <regexp>.find_groups -> <regexp>match_groups
        * <regexp>.find_span -> <regexp>.find

      `<bytes>.match` adapts to the new semantics as well.

    - We remove the `&anchor` attribute because that's the default now.

    - `&no_sub` remains available to override the default choice of the
      matcher type: it'll use the minimal matcher and disable capture group
      support.

0.4.0-1112 | 2020-12-10 10:33:31 +0000

  * GH-25: Add support for manual backtracking to Spicy. If a field is
    marked with ``&try``, a later call to ``self.backtrack()``
    anywhere down in the parse tree will return to that position and
    continue there. See the documentation for more, including an
    example. (Robin Sommer, Corelight).

  * Support &eod for vector parsing. (Robin Sommer, Corelight)

  * Fix Sphinx helper script that emits command lines. (Robin Sommer,

0.4.0-1106 | 2020-12-10 10:10:16 +0000

  * Make capture groups available inside hooks of regular expression fields.
    (Robin Sommer, Corelight)

    Example:

         x: /(a.c)(de*f)(h.j)/ {
    print $1, $2, $3;
}

    This will print the pieces corresponding to the three groups inside the
    expression.

    Couple notes:

        - We don't make $0 available as that would be the same as `$$`.

        - Matching with capture groups is more expensive that without. If
          you don't use any groups in the regexp, the overhead is
          automatically removed. If you use groups, but don't need them to
          capture, add `&nosub` to the field.

  * Make new captures() method available on regexp matching state in
    HILTI. (Robin Sommer, Corelight)

  * Fix argument mismatches between Spicy generated C++ prototypes and
    Zeek plugin runtime code. (Robin Sommer, Corelight)

    We also add a regression test.

    Closes #571. (Benjamin Bannier, Corelight)

  * GH-589: Fix "'_debug’ was not declared in this scope" build error (Robin Sommer, Corelight)

  * Mention header precompilation in installation docs. (Benjamin Bannier, Corelight)

  * Disable precompiled headers for gcc CI job.

    While mixing GCC and Clang with precompiled headers is an issue for JIT
    (JIT always uses Clang to compile modules while precompiled headers are
    created with the compiler used to compile Spicy itself), we disable
    precompiled headers for the non-JIT, GCC job since GCC emits a
    non-suppressible warning, see
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89808,

        build/hilti/runtime/include/hilti/rt/libhilti.h:3:9: error: #pragma once in main file [-Werror]
            3 | #pragma once
              |         ^~~~
        cc1plus: all warnings being treated as errors

    Instead of not treating warnings as errors anymore we disable precompiled
    headers in this build since it does not use them anyway. (Benjamin Bannier, Corelight)

  * Add missing include. (Benjamin Bannier, Corelight)

  * Optionally precompile libhilti.h.

    This patch adds precompilation of libhilti.h for developer setups. This
    header is included in all files during JIT, and precompiling it can for
    individual files reduce JIT time by up to 30%. This behavior can be
    disabled by setting the CMake option `HILTI_DEV_PRECOMPILE_HEADERS=OFF`.

    Specifically, we add a cmake target which creates debug and release
    versions of a precompiled libhilti.h. We modify HILTI's built-in
    CXXFLAGS to check for the presence of the needed precompiled header in
    the expected location. We expect the header either in a specific
    location in the build directory, or optionally in a version directory in
    `$HOME/.cache/spicy`.

    In this patch we enable use of the precompiled header only during JIT,
    but e.g., not when building Spicy targets. This allows us to profit from
    faster JIT while still making efficient use of e.g., ccache.
    Additionally, this approach allows us to punt on fixing a number of
    issues in header files which get exposed during JIT (JIT artifacts are
    not affected at the moment).

    The original goal was to precompile lihilti.h before installation which
    is not reached. In general, it seems that precompiled headers are not
    intended to be moved after creation. This poses a challenge when the
    header gets installed: while we could in principle generate the
    precompiled header at the final location during install time, this seems
    not reliably possible when generating packages which can be expanded in
    arbitrary locations.

    Additionally, we also install a script for users to take advantage of
    precompiled headers once Spicy has been installed. (Benjamin Bannier, Corelight)

  * GH-497: Add support for packet analyzers to Zeek plugin. (Robin Sommer,
    Corelight)

    Zeek's master branch received support for adding low-level "packet
    analyzers" through plugins. This extends the Spicy plugin to support that.
    The documentation gained a new section explaining how to sue that.

    Note: This feature will not "officially" be supported until Zeek 4.0
    comes out (because we don't have Zeek master in CI).

  * GH-522: Switch filesystem impl over to ghc::filesystem.

    Closes #522. (Benjamin Bannier, Corelight)

  * Fix use of uninitialized value when numbering unit fields.

    When were using a non-const member function to call a delegated base
    class constructor. Since at the point where the member function was
    called the derived class was not fully constructed, the members it
    accessed and mutated were uninitialized, we were reading from an unset
    variable, attempting to set it, and then overwrote its values when the
    member initializer was triggered (after the base class was constructed).
    This lead to unit field indices set to large value which were not usable
    down the line.

    We now delegate maintaining the field counter to a mixin class which can
    be constructed before the base class needing its state. (Benjamin Bannier, Corelight)

  * Add support for new %print hook to Spicy units. (Robin Sommer,
    Corelight)

    This allows a unit to customize its appearance when printed (or
    more generally: rendered into a string).

    Example:
#cat test.spicy
        public type Test = unit {
        on % init { print self; }
    f1:
        uint32;
    f2:
        uint8;
        on % done { print self; }

        on % print {
            local f1 = "-";
            local f2 = "-";

                if ( self?.f1 )
                    f1 = "%s" % self.f1;

                if ( self?.f2 )
                    f2 = "%s" % self.f2;

                return "%s|%s" % (f1, f2);
        }
    };

#printf '\x00\x00\x00\x01\x02' | spicy - driver test.spicy
        -|-
        1|2

  * Allow customizing the string rendering of HILTI structs. If a

    - Add a CI master step to validate Homebrew formula works.
    - Add missing Cirrus CI instance to Homebrew task.
    - Build compiler toolchain by default when configuring directly from CMake.
    - Bump default Zeek package in Docker images to more recent version.
    - Fix removal of build directory in CentOS 8 Docker container.
    - Increase sleep amount in test to make time measurable in CI.
    - Speed up test `spicy.types.unit.trimming`.

  * Help clang-tidy understand control flow in a couple of places.
    (Benjamin Bannier, Corelight)

0.4.0-918 | 2020-10-06 12:23:08 +0200

  * Introduce the notion of Spicy-specific compiler options.

    So far, we only had codegen options for the HILTI compiler. This
    change allows Spicy to track options as well that control specifics of
    how the Spicy-to-HILTI code generations operates. Includes a couple of
    things:

            - As there's no appropriate global state on the Spicy side
              where we could story options easily, we extend the
              HILTI-side options struct with the notion of "auxiliary
              options", described by key/value pairs. Spicy can then store
              its options in there.

            - We derived a separate spicy::Driver from hilti::Driver to
              customize behaviour.

            - We introduce hooks into the hilti::Driver to add support for
              additional command line options. This remains a bit ad-hoc
              for now. At some point, we'll clean up of command-line
              handling generally works across the various tools, we have
              quite a bit of code duplication there right now.

            - This introduces a Spicy-side `-Q` option to record stream
              offsets during parsing. Right now, the option isn't having
              any effect yet, the implementation is going to come in a
              subsequent commit. spicy-dump's previous `-o` is renamed to
              `-Q` as well. (Robin Sommer, Corelight)

  * Add an option to emit data offsets from spicy-dump.

    This patch adds an option `-o` to `spicy-dump` which can be used to
    trigger outputting of the stream offsets where unit fields were parsed
    from. (Benjamin Bannier, Corelight)

  * Make parser struct `__offset` member accessible from Values. (Benjamin Bannier, Corelight)

  * Store field offsets during parsing. (Benjamin Bannier, Corelight)

  * Make unit fields store their unit-wide field counter.

    Initially the parser will create unit fields as `UnresolvedField`s. This
    patch adds an `_index` field and accessor for this field which will
    be used to number all unit fields in the final, fully constructed and
    resolved unit so offsets can be computed. (Benjamin Bannier, Corelight)

  * Store whether a struct field is internal on type level. (Benjamin Bannier, Corelight)

  * Fix `type::struct_::Field::is*` methods to return booleans.

    These functions were previously returning optional field values which
    carry no information beyond being set or not. This patch changes these
    methods to return booleans instead. (Benjamin Bannier, Corelight)

  * Fully type constructions of empty optional values. (Benjamin Bannier, Corelight)

  * Make `rt::Map::contains` `const`. (Benjamin Bannier, Corelight)

0.4.0-903 | 2020-09-28 18:42:38 +0000

  * Reorganize source code to allow for building the runtime library
    standalone. This adds a corresponding configure option:
    --build-toolchain=yes/no (default: yes)

  * Add configure option --disable-zeek-plugin-install to disable
    installing the Zeek plugin into Zeek's plugin path. (Robin Sommer,
    Corelight)

  * Add CMake module that enables Zeek plugins to build Spicy parsers.

  * Rename Zeek plugin to "_Zeek::Spicy" to work-around a loading
    order issue in Zeek. (Robin Sommer, Corelight)

  * Turn all 3rdparty code into proper git submodules. (Robin Sommer,
    Corelight)

  * Make using Gold linker default in CMake config. This is no change
    from when using "configure", but it changes the default when
    running "cmake" directly. (Robin Sommer, Corelight)

  * Fix configuration of Gold linker to apply to cmake modules as
    well. (Robin Sommer, Corelight)

  * Extend hilti-config and spicy-config with options to print the
    runtime's C++ include directories. (Robin Sommer, Corelight)

  * Avoid needing "which" in configure. (Robin Sommer, Corelight)

    constructors. (Benjamin Bannier, Corelight)

  * GH-503: Fix constructor `interval_ns` to accept unsigneds like

  * Move resolving of exceptions' backtrace symbols to point-of-use
    for improving performance. (Robin Sommer, Corelight)

  * Fix problem with fiber reuse. (Robin Sommer, Corelight)

  * Fix a unit test that's using multiple filters. (Robin Sommer,
    Corelight)

  * Add macOS work-around for problem with doctests' platform
    detection. (Robin Sommer, Corelight)

  * When configured for debug mode, build tests without -O and link
    them against {hilti,spicy}-rt-debug. (Robin Sommer, Corelight)

0.4.0-874 | 2020-08-27 14:21:57 +0200

  * Update parser lookup tables exclusively from `spicy::rt::init`.

    We previously were updating `globalState()->parsers_by_mime_type` from
    `registerParser` while `globalState()->parsers_by_name` was updated by
    `init`. This patch makes `init` the only function updating the parser
    lookup tables `parsers_by_name` and `parsers_by_mime_type`. (Benjamin Bannier, Corelight)

  * Remove unintentional `return` in `rt::haveEod`. (Benjamin Bannier, Corelight)

  * Avoid creating vain global state in `spicy::rt::{
            done, isInitialized
        }`. (Benjamin Bannier, Corelight)

  * Reinitialize default parser when reinitializing spicy::rt library. (Benjamin Bannier, Corelight)

0.4.0-861 | 2020-08-24 13:04:33 +0200

  * Diagnose invalid `zlib::Stream`s.

    When a `zlib::Stream` enters a failed state it cannot be reused
    anymore. Previously we would return empty data whenever such a stream
    was used again nevertheless. Since empty data is a valid result of
    decompressing non-empty input this leaves users with no good way to
    catch such scenarios after the fact.

    This patch modifies `zlib::Stream::decompress` to now throw an exception
    instead of returning valid but empty data. (Benjamin Bannier, Corelight)

0.4.0-855 | 2020-08-24 10:56:17 +0000

  * Fix Cirrus CI file for Alpine 3.12. (Robin Sommer, Corelight)

0.4.0-854 | 2020-08-24 08:41:23 +0000

  * Switch Dockerfile for Alpine from 3.11 to 3.12.

  * Compile code with debug information also when in release mode.
    (Robin Sommer, Corelight)

  * Compile the toolchain with -O3 instead of -O2. (Robin Sommer,
    Corelight)

  * Always link against thread library. The performance of some of our
    runtime code depends on whether the executable is linked against
    pthread or not. (Robin Sommer, Corelight)

0.4.0-849 | 2020-08-24 08:39:14 +0000

  * Fiber runtime library updates. (Robin Sommer, Corelight)

    - Fix state tracking in fibers. When taking a fiber from the
      cache, we would reset its state on INIT, which then led to
      restarting it from scratch instead of reusing the already
      running loop.

    - Add a function to fill the fiber cache with preinitialized
      instances.

    - Track number of fiber initialization in statistics.

    - Unify fiber debug logging.

0.4.0-843 | 2020-08-21 13:10:42 +0200

  * Consistently deal with `std::filesystem` still being experimental in hilti-rt. (Benjamin Bannier, Corelight)

0.4.0-840 | 2020-08-21 10:04:02 +0200

  * Prevent use after free in `rt::base64::finish`. (Benjamin Bannier, Corelight)

0.4.0-833 | 2020-08-19 11:06:44 +0200

  * Add assertion catching out-of-bounds HILTI module access. (Benjamin Bannier, Corelight)

  * Add check to prevent nullptr dereference in `hilti::rt::done`. (Benjamin Bannier, Corelight)

  * Add missing context cleanup in `hilti::rt::done`.

    We configure a `Context` owned by `GlobalState` in `hilti::rt::init`.
    Since we destruct that context in `hilti::rt::done` we also need to
    reset the context as we would otherwise leave a dangling refernence
    behind. (Benjamin Bannier, Corelight)

  * Call out gitlint in commit message style guidelines. (Benjamin Bannier, Corelight)

  * Remove guidance on not rebasing development branches. (Benjamin Bannier, Corelight)

  * Add developer manual section on pre-commit linters. (Benjamin Bannier, Corelight)

  * Add pre-commit linter for commit messages. (Benjamin Bannier, Corelight)

0.4.0-819 | 2020-08-19 11:05:55 +0200

  * Explicitly set locale in centos Docker container.

    `hilti::rt::init` needs to be able to set the locale on the host system
    and will abort with a fatal error if it cannot do so. This patch makes
    sure this is possible in the centos-8 Docker container provided by us.

    Note: This already worked in BTests since its config file enforces the
    needed environment variables. This patch fixes it also for standalone
    usage of Spicy (and now e.g., the `locale` command emits no more
    errors). (Benjamin Bannier, Corelight)

0.4.0-817 | 2020-08-18 11:24:52 +0200

  * Add `hilti::rt::Library::symbol`.

    This patch adds a new member function `Library::symbol` which can be
    used to obtained a symbol from a specific library.

    While currently `Library` users just call `::dlsym` globally to obtain a
    symbol, this becomes ambiguous if multiple libraries in the process image
    provide similarly named symbols. Instead they could hold handles to
    all interesting libraries and obtain symbols with the added function.
    With that we could also `::dclose` libraries in the `Library`
    destructor; we'll leave that change for a later point. (Benjamin Bannier, Corelight)

  * Fix warning potentially emitted from `rt::Library` destructor. (Benjamin Bannier, Corelight)

  * Fix format string in `rt::createTemporaryFile`. (Benjamin Bannier, Corelight)

  * Extend error message when `rt::Library::save` fails. (Benjamin Bannier, Corelight)

  * Change CI job to use non-privileged user.

    At least on ubuntu `root` seems to be able to modify even read-only
    directories which makes it hard to write tests checking handling of
    permission errors.

    Change the image used in CI to use a non-privileged user instead. (Benjamin Bannier, Corelight)

  * Change directory used for ccache store in CI.

    We were originally using `/var/spool/ccache` which could require
    extended privileges to create. Switch over to use `/tmp/ccache` which
    should be easier to create even for unprivileged users. (Benjamin Bannier, Corelight)

  * Prevent `rt::Resumable::get` from leaking non-HILTI exceptions. (Benjamin Bannier, Corelight)

  * Make `hilti::rt::Resumable`'s operator bool explicit. (Benjamin Bannier, Corelight)

  * Consistently provide stringification for all exceptions. (Benjamin Bannier, Corelight)

  * Add comparison operators to `rt::Backtrace`. (Benjamin Bannier, Corelight)

  * Fix `to_string_for_print` for `DeferredExpression`.

    Since `DeferredExpression` is a template itself we cannot specialize the
    master template of the `detail` namespace; instead we need to provide an
    overload. (Benjamin Bannier, Corelight)

0.4.0-798 | 2020-08-14 07:25:00 +0000

  * CI: Move Zeek package specs back into tasks to work around Cirrus
    issue, per https://github.com/cirruslabs/cirrus-ci-docs/issues/692.
    (Robin Sommer, Corelight)

0.4.0-796 | 2020-08-14 07:20:31 +0000

  * Embed version information into HLTO files that encodes information
    about the HILTI version/config they were built with.  (Robin
    Sommer, Corelight)

    We use this for detecting (1) mismatches in the HITLI version used
    for building vs running, and (2) running an optimized HLTO file
    with a debug runtime. In both cases, the runtime will print a
    warning to stderr, but still proceed processing the library.

    Note that this is breaking change that will prevent HLTOs built
    with earlier versions from loading now.

  * Add option -U to tools that summarizes runtime resource
    consumption at termination. The measurement excludes time spent
    for startup/termination. (Robin Sommer, Corelight)

  * Use cout/cerr in debug logger instead of reopening them
    separately. Output can get mixed up otherwise if other places
    write to cout/cerr directly. (Robin Sommer, Corelight)

  * Update nlohmann-json and move to top-level 3rdparty directory.
    (Robin Sommer, Corelight)

0.4.0-789 | 2020-08-11 07:47:30 +0000

  * Lots of new test coverage for HILTI runtime library: references,
    debug logger, configuration, safe-int, iterator, backtrace; along
    with related fixes and cleanups. (Benjamin Bannier, Corelight)

0.4.0-737 | 2020-08-11 07:39:31 +0000

  * Fix exception handling across library boundaries. (Robin Sommer,
    Corelight)

  * Allow limiting the "%port" of a unit to a specific direction.
    (Robin Sommer, Corelight)

    We now allow to add attributes `&originator`/`&responder` to a `%port`
    unit property to limit it to the corresponding direction of a session.
    When selecting a parser through `--parser <port>` in spicy-driver, one
    can now add `%orig` or `%resp` to the port to indicate the desired
    directionality. If one leaves that off, only parsers are selected that
    have no directionlity defined (i.e., just like it used to be).

  * Add batch input mode to spicy-dump. spicy-dump gains an option -F
    to process multiple interleaved input streams pre-recorded in a
    batch input file. The format of that file is described in the
    manual, and there's a Zeek script generating batch files from PCAP
    input traces.  (Robin Sommer, Corelight)

  * When naming a parser to use through "spicy-driver -p XXX", one can
    now also specify a port ("80/tcp") or a MIME type
    ("application/text") if the desired Spicy unit defines a
    corresponding property. See the documentation of spicy-driver for
    more. (Robin Sommer, Corelight)

  * Port Zeek plugin to new driver stateful matching API. (Robin
    Sommer, Corelight)

0.4.0-730 | 2020-08-11 07:38:44 +0000

  * Switch to Zeek 3.2.0 release packages for CI. (Robin Sommer,
    Corelight)

  * Add helper Makefile to build and run the CI docker image locallly.
    (Robin Sommer, Corelight)

0.4.0-725 | 2020-08-05 12:44:26 +0200

  * Remove conversion of `rt::Time` to `bool`. (Benjamin Bannier, Corelight)

  * Fix assignment operator for `rt::Union` of non-copyable types. (Benjamin Bannier, Corelight)

  * Fix format string error possibly triggered when adding Times and Intervals. (Benjamin Bannier, Corelight)

0.4.0-716 | 2020-08-03 22:24:56 +0200

  * Make default-constructed `rt::Address` instances invalid. (Benjamin Bannier, Corelight)

  * Make `rt::Address` remember its address family.

    This class was previously unable to distinguish IPv4 and IPv6 addresses
    with all bits sets to zero from each other. By explicitly storing its
    address family we are able to distinguish them, and can also preserve
    the address family across operations like masking. (Benjamin Bannier, Corelight)

  * Bump doctest to 2.4.0. (Benjamin Bannier, Corelight)

  * Validate prefix length inputs when constructing `rt::Network` values. (Benjamin Bannier, Corelight)

0.4.0-703 | 2020-08-03 07:41:51 +0000

  * GH-444: Port Zeek plugin to Zeek 3.2. (Robin Sommer, Corelight)

  * GH-323: Suppress bogus warning by Zeek when installing our plugin.
    (Robin Sommer, Corelight)

  * Extend EVT file syntax with @if/@else/@endif preprocessor directives.

    For now, we support one type of expression for "@if": a Zeek version check. Example:

        @if ZEEK_VERSION < 30200
        ....
        @else
        ....
        @endif (Robin Sommer, Corelight)

    Also collecting all the Zeek includes into zeek-compat.h. (Robin Sommer, Corelight)

  * Fix frequent off-by-one errors in EVT error message locations.
    (Robin Sommer, Corelight)

0.4.0-691 | 2020-07-31 15:19:57 +0200

  * Emitted fully typed initializer lists in codegen.

  * Correctly handle flipping with zero valid bytes in `rt::integer::flip`. (Benjamin Bannier, Corelight)

  * Add additional precondition checks to `rt::integer::bits`. (Benjamin Bannier, Corelight)

  * Consistently use `ntohX` type functions for `rt::integer::ntohX`. (Benjamin Bannier, Corelight)

0.4.0-681 | 2020-07-23 14:55:25 +0000

  * Fix potential invalid iterator deref in debug output. (Robin Sommer, Corelight)

  * Add operator "bytes += uint8" for adding a single byte. (Robin Sommer, Corelight)

  * Fix missing filter end-of-input signal. (Robin Sommer, Corelight)

  * GH-423: Remove C{,XX}_SYSTEM_INCLUDE_DIRS cmake flags. (Robin
    Sommer, Corelight)

    If this functionality is needed, set CXX_FLAGS instead during
    configure, e.g.:

        CXXFLAGS="-isystem /opt/rh/devtoolset-9/root/usr/include/c++/9" ./configure ...

  * GH-441: Fix generation of lists of reserved words. (Robin Sommer, Corelight)

  * GH-449: Fix documentation example. (Robin Sommer, Corelight)

0.4.0-670 | 2020-07-20 15:25:04 +0000

  * GH-415: Add missing type coercion for parameterized types. (Robin
    Sommer, Corelight)

  * GH-395: Fix tuple constructor expressions to not return a type
    until all elements are fully resolved. (Robin Sommer, Corelight)

  * GH-402: Allow switch statements without any "case". (Robin Sommer,
    Corelight)

  * GH-387: Extend a test's life time. (Robin Sommer, Corelight)

0.4.0-661 | 2020-07-16 07:06:14 +0000

  * Fix build failures from building against Zeek 3.2 dev versions.
    (Tim Wojtulewicz, Corelight)

0.4.0-659 | 2020-07-16 06:34:30 +0000

  * GH-352: Add chapter on custom host applications to manual. (Robin
    Sommer, Corelight)

  * Series of smaller documentation updates. (Robin Sommer, Corelight)

    * Add documentation for types time/interval/optional.
    * Add list of reserved keywords.
    * Update debugging sections.
    * Add note about commutativity to operator documentation where applicable.
    * Add note about checking if optional unit variables remains unset still.
    * Fix typo in documentation for 'print'.
    * Fix an operator's description.

  * GH-408: Remove "time + time" operator. (Robin Sommer, Corelight)

  * GH-404: Add `time_ns(X)` and `interval_ns(X)` expressions to
    instantiate values with nanosecond resolution. (Robin Sommer,
    Corelight)

  * Extend `{hilti,spicy}-config` with a `--dynamic-loading` option.
    This adapts `--ldflags` for applications that want to dynamically
    load precompiled parsers. (Robin Sommer, Corelight)

  * Make `&cxxname` usable for user code: The code generator now
    automatically adds prototypes for the corresponding C++ functions.
    To optionally disable that, a new attribute `&have_prototype` has
    been added. We also no longer require explicit global scoping for
    `&cxxname` IDs. (Robin Sommer, Corelight)

  * Fix joint usage of options `spicyc` options `-cKo`. This would end
    up saving only the linker code, not the combined parsing + linker
    code, in the specific output file. (Robin Sommer, Corelight)

0.4.0-645 | 2020-07-16 06:33:23 +0000

  * GH-423: Update configure's usage message. (Robin Sommer,
    Corelight)

  * GH-433: Add support for declaring constants with explicit types.
    (Robin Sommer, Corelight)

0.4.0-641 | 2020-07-14 06:13:11 +0000

  * GH-429: Fix generation of C++ prototypes for host applications.
    (Robin Sommer, Corelight)

0.4.0-639 | 2020-07-13 10:01:31 +0000

  * GH-400: Fix build with static libraries. (Robin Sommer, Corelight)

  * Fix ill-defined order of internal HILTI plugin execution. (Robin
    Sommer, Corelight)

  * Remove JIT's {init,finish}Runtime() methods. They were no-ops
    already. (Robin Sommer, Corelight)

0.4.0-634 | 2020-07-09 12:32:17 +0200

  * Lots of new & updates unit tests for the HILTI runtime. (Benjamin Bannier, Corelight)

  * Remove `AddressFamily::` prefix when stringifying values. (Benjamin Bannier, Corelight)

0.4.0-612 | 2020-07-08 15:21:20 +0000

  * GH-39: Add `spicy-dump`, a new standalone command line application
    that compiles and executes Spicy parsers on the fly and prints out
    the parsed information at the end in either a readable, custom
    ASCII format, or as JSON. (Robin Sommer, Corelight)
#echo "GET /index.html HTTP/1.0" | spicy - dump my - http.hlto
        MyHTTP::RequestLine {
        method:
            GET uri : / index.html version : MyHTTP::Version {
            number:
                1.0
            }
        }

#echo "GET /index.html HTTP/1.0" | spicy - dump - J my - http.hlto
        {
            "method" : "GET", "uri" : "/index.html", "version" : { "number" : "1.0" }
        }

  * GH-56: Add reflection API to libhilti for dynamic, runtime
    inspection of parsed units. This includes:

      * A "typeinfo(X)" expression for HILTI that, at runtime, wwill
        yield a pointer to a new `hilti::rt::TypeInfo`` struct
        describing the type of `X`, which can be a type or an
        expression.

      * `include/rt/type-info.h` builds out a comprehensive set of
        classes to describe HILTI types, and to access their values
        generically, at runtime.

      * A 3rd kind of host application-side parse function for public
        units. Spicy's driver's processInput() now uses that.

  * Change string rendering of ports to skip "Protocol::" prefix.
    (Robin Sommer, Corelight)

  * Fix bug in move assignment operator of ValueReference. (Robin
    Sommer, Corelight)

  * Add stringification for exception type. (Robin Sommer, Corelight)

  * Add stringification for "any" type. (Robin Sommer, Corelight)

  * Add missing &internal attributes to some codegenerated struct
    fields. This hides them from user visible output. (Robin Sommer,
    Corelight)

  * Add equality operator to regexp type. (Robin Sommer, Corelight)

  * Add operator<< for regexp. (Robin Sommer, Corelight)

  * Support anonymous namespaces in C++ output. (Robin Sommer,
    Corelight)

  * Add missing printer code for iterator<set> and iterator<map>.
    (Robin Sommer, Corelight)

  * Add const version of vector iterator's dereference operator.
    (Robin Sommer, Corelight)

  * Add -O0 to libhilti/libspicy for debug builds.  (Robin Sommer,
    Corelight)

0.4.0-572 | 2020-07-08 11:36:53 +0200

  * Fix parsing of `rt::Port` for out-of-range port values. (Benjamin Bannier, Corelight)

0.4.0-552 | 2020-07-03 15:47:06 +0200

  * Switch `real::unpack` error reporting to use `rt::Result`. (Benjamin Bannier, Corelight)

0.4.0-549 | 2020-07-01 15:03:27 +0200

  * Remove unintended conversion of `rt::Result` to `bool`.

0.4.0-547 | 2020-07-01 11:41:06 +0200

0.4.0-538 | 2020-06-30 08:08:16 +0000

  * Fixed semantics of `hilti::rt::Interval`-bool conversions. They
    now return true for non-zero intervals. (Benjamin Bannier,
    Corelight)

  * Add tests of `rt::Interval` stringification. (Benjamin Bannier, Corelight)

  * Add tests of `result::Error` stringification. (Benjamin Bannier, Corelight)

0.4.0-532 | 2020-06-30 08:03:40 +0000

  * Add a DHCP analyzer. (Benjamin Bannier, Corelight)

  * Fix filename in getting started docs. (Dirk Loss)

  * Move reporting logic for --report-times so that it always executes
    when the HILTI-side driver destructs. (Robin Sommer, Corelight)

  * Fix header inclusion in Spicy plugin. (Benjamin Bannier, Corelight)

  * Remove unused `is_optional` type trait. (Benjamin Bannier,
    Corelight)

  * Enable translation of optional types on the Spicy-Zeek interface.
    (Benjamin Bannier, Corelight)

0.4.0-525 | 2020-06-26 14:55:08 +0200

  * Add dedicated method to resize and assign a vector. (Benjamin Bannier, Corelight)

0.4.0-522 | 2020-06-24 22:24:34 +0200

  * Fix `hilti::rt::is_optional` so it applies to const and ref of optionals also. (Benjamin Bannier, Corelight)

0.4.0-520 | 2020-06-24 06:59:04 +0000

  * GH-398: Remove duplicate spicy-driver CMake target. (Benjamin
    Bannier, Corelight)

0.4.0-518 | 2020-06-24 06:50:48 +0000

  * GH-140: Add "&requires"/"%requires" unit attribute/property.
    (Robin Sommer, Corelight)

    Fields may now use an attribute ``&requires=EXPR`` to enforce
    additional constraints on their values. ``EXPR`` must a be boolean
    expression that will be evaluated after the parsing for the field
    has finished, but before any hooks execute. If ``EXPR`` returns
    ``False``, the parsing process will abort with an error, just as
    if the field had been unparsable in the first place.

    One can similarly enforce conditions globally at the unit level
    through a property ``%requires = EXPR``, which will be evaluated
    once the unit has been full parsed, but before any ``%done`` hook
    executes. If ``EXPR`` returns ``False``, the unit's parsing
    process will abort with an error.

  * Add Doxygen output to Sphinx documentation. It's integrated into
    the "Read the Docs build". Locally, "make doxygen" will run it.
    (Benjamin Bannier, Corelight)

  * Clean up Sphinx custom extension. (Benjamin Bannier, Corelight)
    - Remove use of `sphinx.locale.l_`
    - Format with autopep8.

0.4.0-510 | 2020-06-23 16:16:43 +0200

  * GH-386: Add codegen for Spicy time difference. (Benjamin Bannier, Corelight)

0.4.0-508 | 2020-06-22 06:03:34 +0000

  * Series of improvements for utility infrastructure (Benjamin Bannier, Corelight)
      - Add tests for `util::escapeBytes`.
      - Add tests for some functions in `hilti::rt::util`.
      - Extend list of supported escape characters in hilti::rt escaping functions.
      - Fix `rt::split` for trailing delimiters.
      - Fix edge cases rt::atoi_n.
      - Fix typos in `hilti/rt/util.h`.
      - Make `rt::util::tuple_for_each` also work on rvalues.
      - Make documentation for `hilti::rt::rtrim` more specific.
      - Remove unused `escape_control` argument to `util::escapeBytes`.
      - Use raw character literals in some `hilti::rt::utils` tests.

  * Fix extraction of event priority in EVT files. (Benjamin Bannier, Corelight)

0.4.0-496 | 2020-06-18 15:46:44 +0000

  * GH-381: Have the code generator fully declare enum types directly
    as part of the forward-declarations block. (Robin Sommer, Corelight)

  * GH-380: Corrections to tutorial. (Duffy Ocraven)

  * Adding short "Next Steps" section to tutorial. (Robin Sommer, Corelight)

0.4.0-492 | 2020-06-17 10:41:13 +0200

  * Move hilti's `util` namespace into the `hilti` namespace. (Benjamin Bannier, Corelight)

0.4.0-490 | 2020-06-17 10:36:36 +0200

  * GH-228: Prevent more overflows when working with hilti::rt Time and Interval (Benjamin Bannier,
    Corelight)
    - Change `hilti::rt::Interval` to use safe integers.
    - Change `hilti::rt::Time` to use safe integers.
    - Fix some typos in `hilti/base/util.h`.
    - Remove hilti-rt-tests dependency on hilti library.
    - Reorganize test cases for `hilti::util`.

0.4.0-484 | 2020-06-16 07:15:25 +0000

  * Add new tutorial chapter. (Robin Sommer, Corelight)

  * Add Zeek-side option "Spicy::enable_print" to control whether the
    output of Spicy-side "print" output is shown. Default is off
    (which is a change in behaviour compared to previous versions).

  * Clean up representation of type arguments and function calls in
    auto-generated operator reference. (Robin Sommer, Corelight)

  * Make the target stream of hilti::print() configurable. Default
    remains standard output. Leaving it unset will silence
    hilti::print(). (Robin Sommer, Corelight)

  * Do not use use "using X === ..." for forward-declaring struct
    types in C++ output, as that could accidentally pull in IDs from
    outer namespaces. (Robin Sommer, Corelight)

  * Fix scanner for accepting comment lines at end of file without
    terminating newline. (Robin Sommer, Corelight)

0.4.0-477 | 2020-06-15 07:36:43 +0000

  * GH-293: Fix precedence of "in" operator. (Robin Sommer, Corelight)

    turn the result into a vector. (Robin Sommer, Corelight)

  * GH-324: Fix error message that was too specific about source type.
    (Robin Sommer, Corelight)

  * GH-325: Fix a couple of segfaults in scope builder when hitting
    invalid code. (Robin Sommer, Corelight)

  * Update spicy-driver usage message. (Robin Sommer, Corelight)

    (Robin Sommer, Corelight)

  * GH-344: Type check assignments and fix constness propagation.
    (Robin Sommer, Corelight)

  * GH-345: Validate type of &default expressions. (Robin Sommer,
    Corelight)

  * Add more debug information about constness to AST. (Robin Sommer,
    Corelight)

0.4.0-467 | 2020-06-15 07:18:03 +0000

  * Redo testing of `hilti::rt::Stream` and clean up implementation (Benjamin Bannier, Corelight)
    - Add Doxygen documentation to `rt::Stream`.
    - Add `begin` and `end` methods for `rt::list::Empty`.
    - Add additional nullptr checks when accessing `rt::Stream` iterator chunks or contents.
    - Fix escaping of `rt::Stream` and `rt::View` in stringification
      to ensure all non-printable byte sequences are escaped.
    - Make `rt::stream::View` iterators be safe by default.
    - Prevent nullptr dereference in `rt::Stream` iterator `chunk` and `content`.
    - Remove `rt::Stream::safe_[begin|end]`.
    - Remove `rt::stream::View::safe_[begin|end]`.
    - Remove `safe_begin` and `safe_end` extension points.
    - Remove unused `Chunk::begin`.
    - Remove unused `rt::Stream::chain` function.
    - Remove unused `rt::Stream::compare` functions.
    - Remove use of unsafe iterators in a few places.
    - Rename `rt::iterator::safe_range` to drop the 'safe' qualifier.
    - Add lots of tests new cases, and reorganize exists test cases.

  * Add `begin` and `end` methods for `rt::list::Empty`. (Benjamin
    Bannier, Corelight)

0.4.0-430 | 2020-06-12 08:07:16 +0200

  * Reenable some already passing clang-tidy checks. (Benjamin Bannier, Corelight)

0.4.0-428 | 2020-06-12 08:06:23 +0200

  * GH-274: Unbreak build for when other Spicy headers are already installed.

    If Spicy headers were already installed into a path somewhere in the
    include lookup, we could have found the same header twice, preferring
    the installed header over the one of the current checkout. This could
    have lead to diagnostics about duplicate definitions since due to use of
    `#pragma once` in our headers the compiler would not have detected that
    a header was already included (and even if it would have detected this,
    it would have included the incorrect header).

    This patch adds include paths from the current checkout before any
    system paths.

0.4.0-426 | 2020-06-09 17:16:13 +0000

  * Increase CI memory limit for Ubuntu Docker further. (Robin Sommer,

    provide default values. (Robin Sommer, Corelight)

  * GH-365: Zeek plugin: Catch if more parameters are given in an EVT
    spec than Zeek expects. (Robin Sommer, Corelight)

  * Remove branch name from Cirrus CI emails due to API limitations.
    (Benjamin Bannier, Corelight)

0.4.0-406 | 2020-06-04 09:14:27 +0000

  * GH-354: No longer allow dashes inside identifiers. (Robin Sommer, Corelight)

  * GH-350: Restrict parsing of attributes and properties to avoid
    ambiguities. (Robin Sommer, Corelight)

  * Clean up the expression mode in the Spicy Bison parser. (Robin Sommer, Corelight)

    This comes with a couple of grammar changes to avoid ambiguitues:

        - "new X" no longer allowes full expressions for X, just values or
          identifiers.

        - Switch cases that use look-ahead now also need to be introduced
          with an arrow, e.g.:

               switch {
      ->a : A;
      ->b : B;
      ->c : C;
  };

  * Reduce resources requested from Cirrus. (Robin Sommer, Corelight)

    for invalid input. (Benjamin Bannier, Corelight)

0.4.0-362 | 2020-06-02 15:20:59 +0000

  * GH-282: Set PATH when building documentation so that we find the
    Spicy tools. (Robin Sommer, Corelight)

  * GH-348: Fix integer overflows in regexp parsing & matching.
    (Robin Sommer, Corelight)

0.4.0-356 | 2020-05-28 10:23:04 +0000

    integration and standalone plugin builds. (Robin Sommer,
    Corelight)

0.4.0-348 | 2020-05-27 13:03:22 +0200

  * GH-335: Add http_all_headers() event to HTTP EVT file.

    The event isn't used anywhere by default in Zeek, but it's a nice
    example of transforming Spicy information on the fly to match a
    Zeek-side event signature.

0.4.0-311 | 2020-05-21 07:54:43 +0000

  * Fix JIT-less build of Zeek plugin. (Robin Sommer, Corelight)

0.4.0-309 | 2020-05-20 12:35:36 +0000

  * GH-299: Support compiling the Zeek plugin without JIT support.
    (Robin Sommer, Corelight)

    If configured with `--disable-jit`, the Zeek plugin will now still
    be built and will support loading pre-compiled HLTO files. The
    plugin will have dependencies only on system libraries, and hence
    can be installed on systems that don't have the Spicy libraries
    available.

    There's also a new configure option `--disable-jit-for-zeek` that
    disables JIT support just for the Zeek plugin, creating the same
    dependency-free result.

  * GH-83: Add standalone tool spicyz to precompile analyzers for
    Zeek. (Robin Sommer, Corelight)

    This replaces the previous shell wrapper around Zeek, meaning that
    we can now precompile Zeek analyzers without actually relying on
    having a Zeek binary itself available. (We continue to require
    access to the Zeek development headers.)

    As a bonus feature, the new spicyz comes with an option "-c
    <prefix>" that, instead of producing a fully compiled HLTO, just
    writes out all the generated C++ code into files, each named
    "<prefix>-<module ID>.cc". This goes along way towards supporting
    compiling Spicy analyzers statically into an application, similar
    to how BinPAC is being used (GH-72).

  * Fix for Bison versions >= 3.6. (Robin Sommer, Corelight)

0.4.0-295 | 2020-05-20 07:23:14 +0000

0.4.0-264 | 2020-05-13 14:18:08 +0000

  * Add an end-to-end TFTP analyzer for Zeek, it comes with a Zeek
    script producing a typical ``tftp.log`` log file. This analyzer is
    a good introductory example because the Spicy side is pretty
    straight-forward. (Robin Sommer, Corelight)

  * GH-306: Do not fail documentation build for broken links.
    (Benjamin Bannier, Corelight)

0.4.0-260 | 2020-05-12 10:37:16 +0000

    - Use less ambiguous form for generated `rt::Vector` constructors.

  * Require Zeek plugin for Zeek protocol parser tests. (Benjamin
    Bannier, Corelight)

0.4.0-234 | 2020-05-11 08:33:55 +0000

  * GH-229: Add a Spicy function to render bytes as hex string.
    (Benjamin Bannier, Corelight)

        ## Returns a bytes value rendered as a hex string.
        public function bytes_to_hexstring(value: bytes) : string;

  *GH - 200 : Add library function `spicy::getenv()` to retrieve environment variables.(Robin Sommer, Corelight)

                  ##Returns the value of an environment variable,
      if set.public function getenv(name
                                    : string)
      : optional<string>;

  * Fix shell commands in `docker/Makefile`. (Benjamin Bannier,
    Corelight)

0.4.0-226 | 2020-05-06 15:12:52 +0000

  * Apply a set of tweaks to specifics of &size. (Robin Sommer,
    Corelight)

    - We now enforce that a field consumes all its &size characters of
      input, unless explicitly overridden where a types allow for that
      (as, e.g., "bytes" does with an additional &eod).

    - We slightly change semantics for parsing bytes: A &size of zero
      will now set the field an empty bytes value; it used to leave
      the field unset.

    - Document that &size works with all fields (which it already
      did).

    - Clean up the implementation of &size.

  * GH-289: Do not perform look-ahead parsing for vectors fed from
    &parse-from/at. (Robin Sommer, Corelight)

  * GH-288: Rename "&until_including" attribute to "&until-including".
    (Robin Sommer, Corelight)

    Bannier, Corelight)

0.4.0-203 | 2020-05-03 15:37:30 +0000

  * GH-265: Require unit properties to end with a semicolon. We were
    inconsistent with that. Note that this will break existing code
    that wasn't using the semicolons, including some examples from the
    documentation (which have been updated). For example, it's now
    `%filter;` instead of `%filter`. (Robin Sommer, Corelight)

    Corelight)

  * GH-262: Allow signs in intN/uintN() constructors. (Robin Sommer,

  * GH-196: Reject container constructors with inconsistent types, and
    coerce elements once the type is known. (Robin Sommer, Corelight)

0.4.0-187 | 2020-04-30 10:26:13 +0000

    block rendering (Robin Sommer, Corelight)

0.4.0-173 | 2020-04-29 08:20:21 +0000

  * Report column information in error messages. Locations are emitted
    as `<line>:<character>` so that e.g., the second character on the
    fourth line would be displayed as `4:2`. This extends to ranges as
    well which look e.g., like `1:1-2:30`. (Benjamin Bannier,
    Corelight)

0.4.0-171 | 2020-04-28 19:08:50 +0000

  * GH-226: Add CI setup for building published Docker images. This
    patch adds an `update_dockerhub` target to `docker/Makefile`,
    which builds, tests and uploads images to Dockerhub. It also
    changes the Dockerfiles in `docker/` back to include Spicy build
    commands, so that they become practically self-documenting
    (Benjamin Bannier, Corelight).
