Current strategy: everything from the top
Things to look at first are the manual changes:
- added tools/rewrite_includes.py
- removed -Idirectives from BUILD.gn
- various compile.sh simplifications
- tweak tools/embed_resources.py
- update gn/find_headers.py to write paths from the top
- update gn/gn_to_bp.py SkUserConfig.h layout
so that #include "include/config/SkUserConfig.h" always
gets the header we want.
No-Presubmit: true

/* Given a path, generate a the desired minimal subset of the original.
|
|
|
|
This does a binary divide-and-conquer on the path, first splitting by
|
|
contours, and then by verbs. The caller passes whether the previous subset
|
|
behaved the same as the original. If not, the subset() call restores the
|
|
prior state before returning a new subset.
|
|
|
|
If a path fails a local test, this reduces the data to the
|
|
minimal set that fails using a pattern like:
|
|
|
|
bool testFailed = true;
|
|
SkPath minimal;
|
|
SubsetContours subsetContours(testPath);
|
|
while (subsetContours.subset(testFailed, &minimal)) {
|
|
testFailed = myPathTest(minimal);
|
|
}
|
|
testFailed = true;
|
|
SubsetVerbs subsetVerbs(testPath);
|
|
while (subsetVerbs.subset(testFailed, &minimal)) {
|
|
testFailed = myPathTest(minimal);
|
|
}
