HeapAllocator stores the pointer returned by HeapAlloc right after the
data block and, after the recent allocator refactoring, the space for
this pointer was not taken into account in the calculation of the final
block size.
Fixes#5830
- Moves fs.rename functions to fs.renameAbsolute to match other functions outside of fs.Dir
- Adds fs.Dir.rename that takes two paths relative to the given Dir
- Adds fs.rename that takes two separate Dir's that the given paths are relative to (for renaming across directories without having to make the second path relative to a single directory)
- Fixes FileNotFound error return in std.os.windows.MoveFileExW
- Returns error.RenameAcrossMountPoints from renameatW
+ Matches the RenameAcrossMountPoints error return in renameatWasi/renameatZ
This implementation tries to do the right thing (TM) by treating the
sign as part of the number itself, therefore the alignment parameter
applies to both the sign and the digits.
In other words the format string `{:>4}` with -1 as input will not
output `- 1` but ` -1`.
And let's default to right alignment for everything as that's what users
want, especially when printing numbers. Many implementations use
different defaults for numeric vs non-numeric types, let's strive for a
consistent behaviour here.
Before merging, do this for every item in the file:
* solve the issue, or
* convert the task to a github issue and update the comment
to link to the issue (and remove "TODO" text from the comment).
Then delete the file.

The API is pretty specific to the implementationt details of the
self-hosted compiler. I don't want to have to independently support
and maintain this as part of the standard library, and be obligated
to not make breaking changes to it with changes to the implementation of
stage2.
* update to the new cache hash API
* std.Target defaultVersionRange moves to std.Target.Os.Tag
* std.Target.Os gains getVersionRange which returns a tagged union
* start the process of splitting Module into Compilation and "zig
module".
- The parts of Module having to do with only compiling zig code are
extracted into ZigModule.zig.
- Next step is to rename Module to Compilation.
- After that rename ZigModule back to Module.
* implement proper cache hash usage when compiling C objects, and
properly manage the file lock of the build artifacts.
* make versions optional to match recent changes to master branch.
* proper cache hash integration for compiling zig code
* proper cache hash integration for linking even when not compiling zig
code.
* ELF LLD linking integrates with the caching system. A comment from
the source code:
Here we want to determine whether we can save time by not invoking LLD when the
output is unchanged. None of the linker options or the object files that are being
linked are in the hash that namespaces the directory we are outputting to. Therefore,
we must hash those now, and the resulting digest will form the "id" of the linking
job we are about to perform.
After a successful link, we store the id in the metadata of a symlink named "id.txt" in
the artifact directory. So, now, we check if this symlink exists, and if it matches
our digest. If so, we can skip linking. Otherwise, we proceed with invoking LLD.
* implement disable_c_depfile option
* add tracy to a few more functions
into smaller exposed components and expose all of them. This makes it
more flexible.
`*const Cache` is now passed in with an open manifest dir handle which
the caller is responsible for managing.
Expose some of the base64 stuff.
Extract the hash helper functions into `HashHelper` and add some more
methods such as addOptional and addListOfFiles.
Add `CacheHash.toOwnedLock` so that you can deinitialize everything
except the open file handle which represents the file system lock on the
build artifacts.
Use ArrayListUnmanaged, saving space per allocated CacheHash.
Avoid 1 memory allocation in hit() with a static buffer.
hit() returns a bool; caller code is responsible for calling final() in
either case. This is a simpler and easier to use API.
writeManifest() is no longer called from deinit() with errors ignored.
Speed up a little the slicing-by-8 code path by replacing the
(load+shift+xor)*4 sequence with a single u32 load plus a xor.
Before:
```
iterative: 1018 MiB/s [000000006c3b110d]
small keys: 1075 MiB/s [0035bf3dcac00000]
```
After:
```
iterative: 1114 MiB/s [000000006c3b110d]
small keys: 1324 MiB/s [0035bf3dcac00000]
```
It turns out that the kernel won't read or write more than 0x7fffffff
bytes in a single call, failing with EINVAL when trying to do so.
Adjust the limit and curse whoever is responsible for this.
Closes#6332
Move block definitions inside while loop.
Use usize for offset. (This still crashes on overflow)
Remove unneeded slice syntax.
Add slow test for Very large dkLen
Master branch added in the concept of library versioning being optional
to main.cpp. It will need to be re-added into this branch before merging
back into master.
