net: remove dependency on unicode #30440
Comments
How much of the net sub-packages should depend on reflectlite? net/rpc and net/http are doable. |
net/http already depends on the world. That's not a goal. And net/rpc is also pretty high level. |

Make context depend on reflectlite instead of reflect in effort to eventually make net no longer depend on unicode tables. With this CL we're down to just: net -> context -> fmt -> unicode tables The next CL can remove context -> fmt.

So the net package doesn't indirectly depend on unicode tables. But we're still not quite there, because a new test added in this CL reveals that we still have a path to unicode via: deps_test.go:570: TODO(issue 30440): policy violation: net => sort => reflect => unicode Updates #30440 Change-Id: I710c2061dfbaa8e866c92e6c824bd8df35784165 Reviewed-on: https://go-review.googlesource.com/c/go/+/169080 Reviewed-by: Ian Lance Taylor <iant@golang.org> Run-TryBot: Ian Lance Taylor <iant@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org>
With the CLs above, we're not all the way back to Go 1.4 sizes, but much of the way:

We compile package sort as part of the compiler bootstrap, to make sure the compiler uses a consistent sort algorithm no matter what version of Go it is compiled against. (This matters for elements that compare "equal" but are distinguishable.) Package sort was compiled in such a way as to disallow sort.Slice entirely during bootstrap (at least with some compilers), while cmd/internal/obj was compiled in such a way as to make obj.SortSlice available to all compilers, precisely because sort.Slice was not. This is all highly confusing. Simplify by making sort.Slice available all the time. Followup to CL 169137 and #30440 (and also CL 40114 and CL 73951).

An unfortunate dependency on unicode has crept into the net package via context -> reflect, introduced mostly in mid 2017 in 538b3a5.
Make context depend on reflectlite instead and fix deps_test.go to enforce that net can't depend on unicode.
