d43ca71	Jameson Nash	12 May 2023, 16:29:37 UTC	macroexpand: stop pre-running the hygiene pass This prepares us to delete the separate hygiene pass, and make it part of lowering resolve-scopes. This affects a few macros which expect to run macroexpand then mangle the result more, and the result of those macros is not already wrapped in `esc()`. The damage seems relatively minor however, and generally a good improvement.	27 February 2024, 18:05:17 UTC
c19c68e	Nicholas Bauer	27 February 2024, 16:17:15 UTC	Add error hint for incorrect stacked indexing (#40934) A common entry level mistake is to try to index a matrix with two sets of brackets, e.g. `a = [1 2; 3 4]; a[1][2] = 5` This will lead to an error that `setindex!()` on the element type of `a` is missing. This PR adds an error hint for the case where a MethodError is raised when `setindex!` is called with a `Number` as the first argument. I considered going broader than numbers, but it seems more likely that this kind of mistake would happen when working with simple number arrays vs. something more advanced. Could also consider if it is possible to do the same for when `getindex()` is called on a `Number`, which emits a BoundsError.

98b3f72	Jishnu Bhattacharya	27 February 2024, 01:16:22 UTC	Fix boundscheck in unsetindex for SubArrays (#53475) These had been copy-pasted incorrectly, and should throw an error if the indices are out of bounds.	27 February 2024, 01:16:22 UTC
a2be715	Jameson Nash	26 February 2024, 21:08:57 UTC	gf: allow method shadowing with exact signatures without deletion (#53415) We already allowed method shadowing for an inexact signature and implicit method deletion by exact signatures, so it was fairly arbitrary to implement it as a deletion for a replacement by an exact signature rather than use the morespecific definition for this. This change should be useful to Mocking libraries, such as Pluto, which previously had a buggier version of this which tried to re-activate or re-define the old methods. There is a bit of code cleanup in here, either of unused features, or of aspects that were broken, or of world_valid computations that were not actually impacting the final result (e.g. when there is a more specific result matches, it does not need to limit the result valid world range because of a less specific result that does not get returned).	26 February 2024, 21:08:57 UTC
7f92880	Jameson Nash	26 February 2024, 21:06:35 UTC	add dedicated IO thread (capability only) (#53422) It has been oft-requested that we have a dedicated IO thread. That actually turns out to already be the case of something that exists, except that we hard-code the identity of that thread as being thread 0. This PR replaces all of the places where we hard code that assumption with a variable so that they are more easily searched for in the code. It also adds an internal function (`jl_set_io_loop_tid`) that can be used to transfer ownership of the loop to any (valid) tid. In conjunction with the prior foreign-threads work and foreign-thread pool, this lets us spawn a dedicate IO-management thread with this bit of code: ```julia function make_io_thread() tid = UInt[0] threadwork = @cfunction function(arg::Ptr{Cvoid}) Base.errormonitor(current_task()) # this may not go particularly well if the IO loop is dead, but try anyways @ccall jl_set_io_loop_tid((Threads.threadid() - 1)::Int16)::Cvoid wait() # spin uv_run as long as needed nothing end Cvoid (Ptr{Cvoid},) err = @ccall uv_thread_create(tid::Ptr{UInt}, threadwork::Ptr{Cvoid}, C_NULL::Ptr{Cvoid})::Cint err == 0 \|\| Base.uv_error("uv_thread_create", err) @ccall uv_thread_detach(tid::Ptr{UInt})::Cint err == 0 \|\| Base.uv_error("uv_thread_detach", err) # n.b. this does not wait for the thread to start or to take ownership of the event loop nothing end ```	26 February 2024, 21:06:35 UTC

This adds `tempname(suffix = "_foo.txt")` to include a suffix in the name and uniquing check. --------- Co-authored-by: Jameson Nash <vtjnash@gmail.com>	26 February 2024, 19:52:42 UTC

4b47cc4	Eric Hanson	26 February 2024, 07:36:47 UTC	Remove stale explicit imports from many stdlibs (#53464) Found via my new https://github.com/ericphanson/ExplicitImports.jl ```julia using ExplicitImports ExplicitImports.inspect_session(; inner=print_stale_explicit_imports) ``` These are not being used in the modules they are being imported into (or in some cases they are being used, but only in a qualified way where the explicit import is unnecessary). It can happen that someone imports a name into a module in order to have it available in that namespace, to then access it from another module (e.g. `TOML.Internals` seems to work like this). I've tried to notice those situations and not remove the imports in cases where I suspect the import is playing such a role, but hopefully CI will figure out if I got it right in all cases. I only looked at stdlibs that happened to be loaded in my Julia session and whose code is in this repo, so there are probably more stale explicit imports out there.	26 February 2024, 07:36:47 UTC

b8a0a39	Valentin Churavy	25 February 2024, 02:48:37 UTC	Prevent tainting native code loading from propagating (#53457) When we use options like code coverage, we can't use the native code present in the cache file since it is not instrumented. PR #52123 introduced the capability of skipping the native code during loading, but created the issue that subsequent packages could have an explicit or implicit dependency on the native code. PR #53439 tainted the current process by setting `use_sysimage_native_code`, but this flag is propagated to subprocesses and lead to a regression in test time. Move this to a process local flag to avoid the regression. In the future we might be able to change the calling convention for cross-image calls to `invoke(ci::CodeInstance, args...)` instead of `ci.fptr(args...)` to handle native code not being present. --------- Co-authored-by: Jameson Nash <vtjnash@gmail.com>	25 February 2024, 02:48:37 UTC
714c6d0	Jeff Bezanson	25 February 2024, 01:26:49 UTC	clarify keyword arg method error message (#53460) This is a nice explanatory message, so I think we should make the wording less obscure.	25 February 2024, 01:26:49 UTC
138aba7	Matt Bauman	23 February 2024, 22:04:29 UTC	improve `--heap-size-hint` arg handling (#48050) Previously, `--heap-size-hint` would silently ignore many flavors of "bad" input, parsing things like "3PB" as 3 bytes. This change makes it significantly less permissive, erroring unless it can parse a number (still relying on the C `sscanf` `%Lf` format specifier there) with an optional unit (case-insensitive, either with or without the trailing `b`). Also test it.	23 February 2024, 22:04:29 UTC
9839aa3	Jameson Nash	23 February 2024, 21:38:06 UTC	free more thread state in jl_delete_thread and GC (#52198) This prevents most memory growth in workloads that start many foreign threads. In the future, we could do even better by moving pages in the heap of an exited thread (and also maybe pooled stacks) elsewhere so they can be reused, and then also free the TLS object itself.	23 February 2024, 21:38:06 UTC
936c8a6	Kristoffer Carlsson	23 February 2024, 20:04:41 UTC	make debug messages for relocatable srcfiles into a separate group (#53446) These create a lot of noisy output that is typically not interesting.

ea1a0d2	Jameson Nash	23 February 2024, 19:59:20 UTC	when loading code for internal purposes, load stdlib files directly(#53326) This bypasses DEPOT_PATH, LOAD_PATH, and stale checks when loading known stdlib code for known purposes from known locations, specifically to avoid the problem that I cannot fix my tools because I have used my tools to break my tools. This helps avoid the situation that the user can break important Pkg, REPL, Socket or similar features simply because they chose to remove `@stdlib` from their environment. For example, if you make an edit to REPL, then this will trigger recompilation and load the edited version: ``` $ ./julia -e 'using REPL' -iq ┌ Info: Precompiling REPL [3fa0cd96-eef1-5676-8a61-b3b8758bbffb] (cache misses: include_dependency fsize change (2), invalid header (10), mismatched flags (1)) └ @ Base loading.jl:2643 julia> ``` But this will load the version that shipped with Julia, regardless of the state of the cache or the source code (unless you delete the cache files): ``` $ ./julia -iq julia> ``` Fixes #53365	23 February 2024, 19:59:20 UTC

923fe2d	Max Horn	23 February 2024, 08:19:02 UTC	Add update mechanism for Terminfo, and common user-alias data (#53285) Now that we take care of terminfo parsing ourselves, having a clear origin and processing method for arriving at our reference terminfo data seems somewhat important. The original form was acquired by re-purposing some pre-processed terminfo data from NCurses (I forget the exact source). I considered adding a separate ingestion/processing script, but it occurred to me that it would make sense to have the method for updating the data file be _in_ the data file, by turning it into a quine. This seems to work rather well, and so long as the NCurses source file format stays the same, updating the terminfo data is now dead simple. While working on the terminfo files, some minor refactors popped up as "probably nice to have". One of which makes the reported number of flags/numbers/strings actually accurate. Lastly, to support the ergonomic use of capability variable names instead of the short (read: uninformative) capname, we now also import the NCurses-recognised extended capabilities, and generate/specify some nice aliases for them. ----- If we separate out the terminfo parser/data into a small stdlib, the state here will be the initial state of the repo.	23 February 2024, 08:19:02 UTC
6e1d062	tecosaur	23 February 2024, 08:16:42 UTC	Add annotate! method for AnnotatedIOBuffer (#53284) The annotate! function provides a convenient way of adding annotations to an AnnotatedString/AnnotatedChar without accessing any of the implementation details of the Annotated* types. When AnnotatedIOBuffer was introduced, an appropriate annotations method was added, but annotate! was missed. To correct that, we refactor the current annotate! method for AnnotatedString to a more general helper function _annotate! that operates on the annotation vector itself, and use this new helper method to easily provide an annotate! method for AnnotatedIOBuffer.	23 February 2024, 08:16:42 UTC

962d833	Jameson Nash	21 February 2024, 20:18:43 UTC	undo breaking change of removing `parent` field from CodeInfo (#53393) This drops the unnecessary breaking change from https://github.com/JuliaLang/julia/pull/53219 by re-adding the optional `parent` field to CodeInfo. A few months ago, I had actually already put together a branch that also fixed Keno's complaints about how it was not set reliably, so I copied that code here also, so that it should get set more reliably whenever a CodeInfo is associated with a MethodInstance (either because it called `retrieve_code_info` to get IR from the Method or `uncompress_ir` to get it from the inference cache). This does not entirely fix Cthulhu's test errors, since I don't see any particular reason to re-introduce the other fields (min_world, max_world, inferred, edges, method_for_inference_limit_heuristics) that got removed or are now set incorrectly, and most errors appear to be instead related to the `Expr(:boundscheck, true/false)` change. However, they could be trivially re-added back as placeholders, if someone encounters a broken package that still needs them.	21 February 2024, 20:18:43 UTC
