This patches libsigsegv to not check the stack vma on Linux, since that
involves reading procfs, and we make very heavy use of sigsegv. This
eliminates most of urbit's performance discrepancy between Linux and
MacOS. These are the benchmarks used; note this is a local MBP vs a
cloud Linux server, and the MBP is almost certainly faster hardware.
We take two benchmarks, one of which decrements 10 million times and the
other simply allocates 125MB of memory. These are the results:
cpu-heavy == =/ n 10.000.000 |-(?~(n n $(n (dec n))))
mem-heavy == =a (bex 1.000.000.008)
macos, cpu-heavy: 6 seconds
macos, mem-heavy: 1 second
linux-before, cpu-heavy: 30 seconds
linux-before, mem-heavy: 160 seconds
linux-after, cpu-heavy 9 seconds
linux-after, mem-heavy 1.3 seconds
This represents a 3x speedup for the cpu-heavy operation and a 120x
speedup for the memory-heavy operation.
This check was used to try to distinguish stack overflow from other
forms of segmentation fault. In the comments in src/handler-unix.c, it
describes three heuristics it uses, depending on what's available from
the OS. In the linux-i386 case, all three are availble, so we simply
disable the slow one. This correctly recognizes stack overflow if you
simply alloca(10000000000).
46a438f introduced use of the stdenv generic builder instead of an
explicit builder.sh script. This was reverted in 1daaf041a as it proved
to cause problems when building on some Linux variants.
This fixes the problem encountered on Linux by calling the standard
configure script with bash in an explicit configurePhase.
Adds a derivation that uses a patched pkg/urbit/vere/lmdb.c that employs
a sixty gigabyte log limit, instead of the default forty. This is
useful for ships e.g. ~zod that receive a lot of traffic on mainnet.
'installPhase' captures all the important stuff that builder.sh
previously did, and use of the generic builder allows stages of the
build to be more easily overridden.
Returns the target %zuse contract configuration to mainnet, and also
tweaks the 'arvo-ropsten' build to use %alef instead of %ames.
Also fixes a merge conflict artifact in nix/ops/default.nix.
0bdced981e introduced the 'arvo-ropsten' derivation. Attempting to
install both 'arvo' and 'arvo-ropsten' via nix-env will result in a
priority error; this assigns a higher priority to 'arvo' to resolve the
conflict.
Fixes#1912.
Arvo testnets typically use Ropsten's deploy of the Azimuth contract
instead of mainnet's. This commit adds an 'arvo-ropsten' derivation for
Arvo as specialised to Ropsten.
In addition to using a different Azimuth address in %zuse, this also
configures %ames and :acme appropriately for running an alternate
network on Ropsten. %ames has its protocol version incremented, and
:acme uses the Let's Encrypt staging API.
Included here are derivations for creating brass and ivory pills using
arvo-ropsten, to boot.
This removes the baked in codedump inspection and wrapper scripts
in favour of downstream tooling overriding this as necessary by
using FROM <image> in their respective dockerfile.
Rather than conditional reconstructing the "urbit/bin/urbit-debug -g"
string everytime using the debug conditional, this information has been
added to the derivation's .meta attribute.
This writes the SSL certs to a temporary file on startup and then
uses environment variables to control OpenSSL and curl so that
they use them. We have to do this because OSX no longer ships the
normal ca pems, and we statically link with these libraries.
* Add cross-compilation for `lmdb`.
* Got built caching working in CI with `cachix`.
* Cache cross compilation dependencies and toolchains.
* Do release builds in CI.
* Upload release builds to `bootstrap.urbit.org` on successful build.
* Lots of optimization work for CI.
* Boot from a solid pill in CI and load arvo with `-A`.
* Increase `vere` HTTP timeout to 15m.
* Move extraneous stuff out of pkg/urbit/*
* s/urb/herb/g
* Removed some boilerplate for `urbit` builds.
* Build urbit tests and run them in the nix build.
