2024-03-29meson: add missing explicit dependency on nlohmann_jsonWinter
Without this, the Meson setup won't bail out if nlohmann_json is missing, leading to subpar DX (and maybe worse, but I'm not entirely sure). Change-Id: I5913111060226b540dcf003257c99a08e84da0de
2024-03-29meson: install missing/generated headerseldritch horrors
one headers (args/root.hh) was simply missing, and the generated headers were not installed. not all of them *should* be installed either, only a select few (and sadly this needs a custom target for each one, it seems) Change-Id: I37b25517895d0e5e521abc1202fa65624de57ed1

2024-03-27Stop vendoring toml11Winter
We don't apply any patches to it, and vendoring it locks users into bugs (it hasn't been updated since its introduction in late 2021). Closes https://git.lix.systems/lix-project/lix/issues/164 Change-Id: Ied071c841fc30b0dfb575151afd1e7f66970fdb9
2024-03-27HOT SALE: 15% off your build times!Jade Lovelace
This was achieved by running maintainers/buildtime_report.sh on the build directory of a meson build, then asking "why the heck is json eating our build times", and strategically moving the json using bits out of widely included headers. It turns out that putting literally any metrics whatsoever into the build had immediate and predictable results. Results are 1382.5s frontend time -> 1175.4s frontend time, back end time approximately invariant.

2024-03-25Input: Replace markFileChanged() by putFile()Eelco Dolstra
Committing a lock file using markFileChanged() required the input to be writable by the caller in the local filesystem (using the path returned by getSourcePath()). putFile() abstracts over this.

2024-03-22build: optionally build and install with mesonQyriad
This commit adds several meson.build, which successfully build and install Lix executables, libraries, and headers. Meson does not yet build docs, Perl bindings, or run tests, which will be added in following commits. As such, this commit does not remove the existing build system, or make it the default, and also as such, this commit has several FIXMEs and TODOs as notes for what should be done before the existing autoconf + make buildsystem can be removed and Meson made the default. This commit does not modify any source files. A Meson-enabled build is also added as a Hydra job, and to `nix flake check`. Change-Id: I667c8685b13b7bab91e281053f807a11616ae3d4
2024-03-20libexpr: unbreak PosTable performanceeldritch horrors
this was mostly an inconvenience for error reporting, but fully broke the debugger (because the debugger does *a lot* of eager position resolution). copying the line offsets into a local and filling that local when empty without also storing the calculated offsets back does kind of ... not cache anything. fixes https://git.lix.systems/lix-project/lix/issues/165 Change-Id: Iccb0ba193ce2f15c832978daecf7b9bebbbe8585

2024-03-18libexpr: associate let exprs with the correct StaticEnveldritch horrors
static env association is from expr to its enclosing scope, but let exprs set their association to their *inner* scope. this skips one level of envs and will cause segfaults if the parent is a with expr. fixes #145 Change-Id: I1d22146110f071ede21b4eed7ed34b5850ef2ef3
2024-03-18libexpr: sort binding name in debuggereldritch horrors
not doing this exposes the binding name order to the annoying interference of parse order on symbol order, which wouldn't be so bad if it didn't make the tests less reliable and, importantly, dependent on linker behavior (due to primop initialization being done in static initializer, and the order of static initializers being defined only within a single translation unit). fixes #143 Change-Id: I3cf417893fbcf19e9ad3ff8986deb7cbcf3ca511

2024-03-18use byte indexed locations for PosIdxeldritch horrors
we now keep not a table of all positions, but a table of all origins and their sizes. position indices are now direct pointers into the virtual concatenation of all parsed contents. this slightly reduces memory usage and time spent in the parser, at the cost of not being able to report positions if the total input size exceeds 4GiB. this limit is not unique to nix though, rustc and clang also limit their input to 4GiB (although at least clang refuses to process inputs that are larger, we will not). this new 4GiB limit probably will not cause any problems for quite a while, all of nixpkgs together is less than 100MiB in size and already needs over 700MiB of memory and multiple seconds just to parse. 4GiB worth of input will easily take multiple minutes and over 30GiB of memory without even evaluating anything. if problems *do* arise we can probably recover the old table-based system by adding some tracking to Pos::Origin (or increasing the size of PosIdx outright), but for time being this looks like more complexity than it's worth. since we now need to read the entire input again to determine the line/column of a position we'll make unsafeGetAttrPos slightly lazy: mostly the set it returns is only used to determine the file of origin of an attribute, not its exact location. the thunks do not add measurable runtime overhead. notably this change is necessary to allow changing the parser since apparently nothing supports nix's very idiosyncratic line ending choice of "anything goes", making it very hard to calculate line/column positions in the parser (while byte offsets are very easy). (cherry picked from commit 5d9fdab3de0ee17c71369ad05806b9ea06dfceda) Change-Id: Ie0b2430cb120c09097afa8c0101884d94f4bbf34
2024-03-18diagnose "unexpected EOF" at EOFeldritch horrors
this needs a string comparison because there seems to be no other way to get that information out of bison. usually the location info is going to be correct (pointing at a bad token), but since EOF isn't a token as such it'll be wrong in that this case. this hasn't shown up much so far because a single line ending *is* a token, so any file formatted in the usual manner (ie, ending in a line ending) would have its EOF position reported correctly. (cherry picked from commit 855fd5a1bb781e4f722c1d757ba43e866d370132) Change-Id: I120c56a962f4286b1ae3b71da7b71ce8ec3e0535
2024-03-18report inherit attr errors at the duplicate nameeldritch horrors
previously we reported the error at the beginning of the binding block (for plain inherits) or the beginning of the attr list (for inherit-from), effectively hiding where exactly the error happened. this also carries over to runtime positions of attributes in sets as reported by unsafeGetAttrPos. we're not worried about this changing observable eval behavior because it *is* marked unsafe, and the new behavior is much more useful. (cherry picked from commit 1edd6fada53553b89847ac3981ac28025857ca02) Change-Id: I2f50eb9f3dc3977db4eb3e3da96f1cb37ccd5174
2024-03-18normalize formal order on ExprLambda::showeldritch horrors
we already normalize attr order to lexicographic, doing the same for formals makes sense. doubly so because the order of formals would otherwise depend on the context of the expression, which is not quite as useful as one might expect. (cherry picked from commit 4147ecfb1c51f3fe3b4adcbd4e753fd487dab645) Change-Id: I3fd0dbdef3ac7447a3a03ff20bb514a0d0f23fb1
2024-03-18keep copies of parser inputs that are in-memory onlyeldritch horrors
the parser modifies its inputs, which means that sharing them between the error context reporting system and the parser itself can confuse the reporting system. usually this led to early truncation of error context reports which, while not dangerous, can be quite confusing. (cherry picked from commit d384ecd553aa997270b79ee98d02f7cf7e1849e6) Change-Id: I677646b5675b12b2faa787943646aa36dc6e6ee3

2024-03-17builtins.nixVersion: return fixed fake versionJade Lovelace
This builtin is only going to cause us problems because we are not Nix, so let's just falsify being in the 2.18 series, since that is the closest target that has any meaning. In future we might want to have a better feature detection mechanism, for when we actually add stuff to some builtin's attr set argument. But builtins.nixVersion is just going to be hopelessly broken and it should be stubbed out.

2024-03-16diagnose duplicated attrs at correct patheldritch horrors
diagnose attr duplication at the path the duplication was detected, not at the path the current attribute wanted to place. doing the latter is only correct if a leaf attribute was duplicated, not if an attrpath was set to a non-attrset in one binding and a (potentially implied) attrset in another binding. fixes #124 Change-Id: Ic4aa9cc12a9874d4e7897c6f64408f10aa36fc82

2024-03-14libexpr: fix elided value counting in printereldritch horrors
using the total-attrs-printed and total-list-items-printed counters to calculate how many attrs were elided only works properly if no nesting is involved. once things do nest the global counter can exceed the size of the currently printed object, leading to unsigned wrapping and great overestimation of elided counts. counting locally in addition to global counts fixes this. these are functional tests because creating these objects requires the evaluator to not be a huge amount of code, and we also want defaults to be tested for cli usage. fixes #14 Change-Id: Icb9a0cb21b2f4bacbc5e9dcdd8c0b9055b4088a7

2024-03-10evaluate inherit (from) exprs only once per directiveeldritch horrors
desugaring inherit-from to syntactic duplication of the source expr also duplicates side effects of the source expr (such as trace calls) and expensive computations (such as derivationStrict).

2024-03-10remove getDerivations deduplicationeldritch horrors
deduplication does not currently work fully, showing derivations multiple times if they have different underlying values. this can happen by selecting the same derivation twice for two different attributes of a set, using inherit-from (which reduces to the previous), importing nixpkgs twice, or any other number of things. since users already have to deal with duplicates for this reason it won't hurt to add *more* duplicates. the alternative would be to deduplicate fully, which would drop derivations that are currently returned and those pose a regression risk.

2024-03-10group inherit by source during Expr::showeldritch horrors
for plain inherits this is really just a stylistic choice, but for inherit-from it actually fixes an exponential size increase problem during expr printing (as may happen during assertion failure reporting, on during duplicate attr detection in the parser) (cherry picked from commit ecf8b12d60ad2929f9998666cf0966475b91e291) Change-Id: Ie55f0cb01a37e766414c31f8d40f51c2c7d106b0
