This change restores the .symtab symbol table files in our flagship
programs (e.g. redbean.com, python.com) needed to show backtraces. This
also rolls back earlier changes to zip.com w.r.t. temp directories since
the right way to do it turned out to be the -b DIR flag.
This change also improves the performance of zip.com. It turned out
mmap() wasn't being used, because zip.com was assuming a 4096-byte
granularity, but cosmo requires 65536. There was also a chance to speed
up stdio scanning using the unlocked functions.
fgets() is now 4x faster which makes Make 2% faster. Landlock Make now
has a builtin $(uniq ...) function that uses critbit trees rather than
functional programming. Since uniq is the most important function this
optimization makes our cold start latency 15% faster.
Landlock Make will no longer sandbox prerequisites that end with a
trailing slash. This means you can use use directory prerequisites
for detecting deleted files when using using globbing, without the
effect of unveiling the entire directory. When you do want make to
unveil directories, you can omit the trailing slash.
Rosetta does something strange to the signal handling registers but
setting SA_SIGINFO prevents the issue from happening. Set the flag
on XNU to work around the issue.
- Polyfill pselect() on Windows
- Add -O NOFILE flag to pledge.com
- Polyfill ppoll() on NetBSD, XNU, and Windows
- Support negative numbers and errno in sizetol()
- Add .RSS, .NOFILE, and .MAXCORE to Landlock Make
- Fix issue with .PLEDGE preventing touching of output files
- Add __watch() function (like ftrace) for logging memory changes
We now guarantee TMPDIR will be defined on a per build rule basis. It'll
be an absolute path. It'll be secure and unique. It'll be rm -rf'd after
the last shell script line in your build rule is executed. If $TMPDIR is
already defined, then it'll be created as a subdirectory of your $TMPDIR
and then replace the variable with the new definition. The Landlock Make
repository will be updated with examples shortly after this change which
shall be known as Landlock Make 1.1.1.
