If you ran some extremely absurd code, it turns out you can cause a
race. This was found by roiedelapluie experimenting! In this case, it
would panic with: fatal error: concurrent map read and map write. This
patch adds the mutex to avoid this rare race.
It was a bit awkward using `mgmt run lang --lang <input>` so instead, we
now drop the --lang, and read the positional argv for the input.
This also does the same for the --yaml frontend.
This makes a small jump to the new etcd stable release. This isn't a
major difference, but it includes an important patch in
7814718c73149e2bbb9517cd02edb8332b621d86 which caused mgmt users to
scratch their heads, since it wasn't obvious that etcd was doing a Fatal
instead of a Panic or an error.
Golang has many exceptions to its "compatibility promise", including the
gofmt output. The fact that they change it arbitrarily for things like
this is absurd. (Remove the patch and run `gofmt` to see for yourself.)
This change re-worked the comment, since include the `gofmt` suggested
line break makes absolutely no sense, and is not convenient.
This will build more accurate graphs, since we could have duplicated
vertex names for distinct vertices. This now builds the correct
topology, even if the labels are duplicated.
I wanted to make sure that the type unification algorithm restricts the
implementation of the class when included, when one of the polymorphic
types is specified with a fixed type. It seems this works! I had the
idea for this test while walking around aimlessly.
The simple type unification algorithm suffered from some serious
performance and memory problems when used with certain code bases. This
adds some crucial optimizations that improve performance drastically.
This quotes printed strings that contain special characters such as
newline. This changes the output of some tests, but makes future tests
that include a raw \n more appropriate.
When include-ing a class, we propagated the scope of the include into
the class instead of using the correct scope that existed when the class
was defined and instead propagating only the include arguments in.
This patch fixes the issue and adds a ton of tests as well. It also
propagates the scope into the include args, in case that is needed, and
adds a test for that as well.
Thanks to Nicolas Charles for the initial bug report.
Since most of our logging goes through a single Logf command, we don't
need the file name information any more. Our hierarchial logging is
sufficient enough.
Eventually we will replace the top-level logger with a more visually
capable logging fixture.
This is a giant cleanup of the etcd code. The earlier version was
written when I was less experienced with golang.
This is still not perfect, and does contain some races, but at least
it's a decent base to start from. The automatic elastic clustering
should be considered an experimental feature. If you need a more
battle-tested cluster, then you should manage etcd manually and point
mgmt at your existing cluster.
This adds a utility function to close a context via a closed signalling
channel, and also functions to wrap and unwrap a wait group into and out
of a context.
Named return params aren't a favourite feature of mine, and they're
rarely used in the resource writing. They keep popping up because I once
used them and we've been copying and pasting code ever since. Get rid of
them all to help prevent the unnecessary spread.
