4 | Subject: [PATCH] cmd/go: make content-based hash generation less pedantic | ||
5 | |||
6 | Go 1.10's build tool now uses content-based hashes to | ||
7 | determine when something should be built or re-built. | ||
8 | This same mechanism is used to maintain a built-artifact | ||
9 | cache for speeding up builds. | ||
10 | |||
11 | However, the hashes it generates include information that | ||
12 | doesn't work well with OE, nor with using a shared runtime | ||
13 | library. | ||
14 | |||
15 | First, it embeds path names to source files, unless | ||
16 | building within GOROOT. This prevents the building | ||
17 | of a package in GOPATH for later staging into GOROOT. | ||
18 | |||
19 | This patch adds support for the environment variable | ||
20 | GOPATH_OMIT_IN_ACTIONID. If present, path name | ||
21 | embedding is disabled. | ||
22 | |||
23 | Second, if cgo is enabled, the build ID for cgo-related | ||
24 | packages will include the current value of the environment | ||
25 | variables for invoking the compiler (CC, CXX, FC) and | ||
26 | any CGO_xxFLAGS variables. Only if the settings used | ||
27 | during a compilation exactly match, character for character, | ||
28 | the values used for compiling runtime/cgo or any other | ||
29 | cgo-enabled package being imported, will the tool | ||
30 | decide that the imported package is up-to-date. | ||
31 | |||
32 | This is done to help ensure correctness, but is overly | ||
33 | simplistic and effectively prevents the reuse of built | ||
34 | artifacts that use cgo (or shared runtime, which includes | ||
35 | runtime/cgo). | ||
36 | |||
37 | This patch filters out all compiler flags except those | ||
38 | beginning with '-m'. The default behavior can be restored | ||
39 | by setting the CGO_PEDANTIC environment variable. | ||
40 | |||
41 | Upstream-Status: Inappropriate [OE specific] | ||
