|
||
|
||
* New Features
|
||
|
||
since my 2015 devconf.cz "Golang: the Good, the Bad, and the Ugly"
|
||
|
||
* New Features
|
||
|
||
- Full compiler rewrite from C to golang (go1.5)
|
||
- No cross-compile bootstrapping needed (go1.5)
|
||
- Shared library support (C->go; go->go; go->C) (go1.5)
|
||
- HTTP/2 support (go1.6)
|
||
- “Vendor” directory feature now default (go1.6)
|
||
- Static-single assignment (SSA) compiler backend (go1.7)
|
||
- Reduction in binary size by 20-30% (go1.7)
|
||
|
||
* New Features
|
||
|
||
- `context` package now included (go1.8)
|
||
- Dynamically loadable “plugins” (go1.8)
|
||
- Testing helpers, safe sync.Map and monotonic time (go1.9)
|
||
- Sparse files for `archive/tar` (g1.10)
|
||
|
||
* Less than Ideal
|
||
|
||
- package management
|
||
|
||
vendoring is a beast
|
||
|
||
[[https://github.com/golang/dep][github.com/golang/dep]]
|
||
|
||
- RPMs

|
||
|
||
- Package guidelines ...

||

|
||
[[https://fedorahosted.org/fpc/ticket/382][FPC #382]]
|
||
|
||
* Less than Ideal
|
||
|
||
- Debugging still is archaic (but hopeful!)
|
||
|
||
Call to action for DWARF and elf folks to contribute. Gdb
|
||
|
||
- FIPS isn’t there yet
|
||
|
||
* Reasons it’s nice
|
||
|
||
- FIPS is in progress!
|
||
|
||
Upstream has a branch working with boringSSL
|
||
We are now working to incorporate and participate in this effort
|
||
|
||
- Debugger traction
|
||
|
||
[[https://github.com/derekparker/delve][github.com/derekparker/delve]]
|
||
|
||
We have understanding with and interest from upstream, but they are not motivated for gdb features
|
||
|
||
* Reasons it’s nice
|
||
|
||
- Learning and ownership of code is easier
|
||
- Multi-arch and gcc-go (which is go1.8.1 as of gcc-7.2)
|
||
|
||
Cross-Compiles are nice (apart from cgo understandably)
|
||
|
||
- Community is diverse and vigilant
|
||
|
||
And growing [[https://trends.google.com/trends/explore?date=all&q=golang&hl=en-US]]
|
||
[[https://octoverse.github.com/]]
|
||
|
||
- Opportunity to talk and learn

||
* Where's Red Hat?
|
||
|
||
- Having an increased presence
|
||
|
||
Still need to have our name present at confs
|
||
Need more speakers
|
||
But as far as active code development, presence and respect, we are formidable
|
||
|
||
- Products are written in it e.g. OpenShift.
|
||
|
||
Openstack teams are working on tooling in golang
