For people using autogenerated summaries, this is one of the hot spots in the memory department.
We don't need to split al the content into words to do proper summary truncation.
This is obviously more effective:
```
BenchmarkTestTruncateWordsToWholeSentence-4 300000 4720 ns/op 0 B/op 0 allocs/op
BenchmarkTestTruncateWordsToWholeSentenceOld-4 100000 17699 ns/op 3072 B/op 3 allocs/op
```
Hugo 0.16 announced support for symbolic links for the root folders, /content, /static etc., but this got broken pretty fast.
The main problem this commit tries to solve is the matching of file change events to "what changed".
An example:
ContentDir: /mysites/site/content where /mysites/site/content is a symlink to /mycontent
/mycontent:
/mypost1.md
/post/mypost2.md
* A change to mypost1.md (on OS X) will trigger a file change event with name "/mycontent/mypost1.md"
* A change to mypost2.md gives event with name "/mysites/site/content/mypost2.md"
The first change will not trigger a correct update of Hugo before this commit. This commit fixes this by doing a two-step check:
1. Check if "/mysites/site/content/mypost2.md" is within /mysites/site/content
2. Check if "/mysites/site/content/mypost2.md" is within the real path that /mysites/site/content points to
Fixes#2265Closes#2273
Atomic operations with 64 bit values must be aligned for 64-bit on x86-32.
According to the spec:
"The first word in a global variable or in an allocated struct or slice can be relied upon to be 64-bit aligned."
The above wasn't enough for the `paginationPageCount` on `SiteInfo`, maybe due to how `SiteInfo` is embedded.
This commit adds a 4 byte padding before the `uint64` that creates the correct alignment.
Fixes#2415
This is the nth attempt to fix an issue by changing the placeholder token pattern, but
now we actually have tests for all the historic trouble cases.
Fixes#2223
So the Permalink gets correct when listing translations.
I have also checked the other relevant places to make sure we do not overwrite node values we need later.
Pointers can be tricky, but lesson learned is: A copy is cheap.
