* add ndjson fuzzer
* reproduce #1310 in the newly added unit test
Had to replace the input, because:
1)
the fuzzer uses the first part of the input to determine
the batch_size to use, so that has to be cut off
2)
the master now protects against low values of batch_size
I also made the test not return early, so the error is triggered.
Introduce cmake option SIMDJSON_DISABLE_DEPRECATED_API (default Off)
which turns off deprecated simdjson api functions by setting the macro
SIMDJSON_DISABLE_DEPRECATED_API.
For non-cmake users, users will have to set SIMDJSON_DISABLE_DEPRECATED_API
by some other means to disable the api.
Closes#1264
This adds a minifier fuzzer. There is also an utf-8 fuzzer, but it is disabled until #1187 is fixed.
Run all fuzzers bug the utf-8 one in the github CI fuzz.
This enables the minify fuzzer, which has been disabled because it did not pass the oss-fuzz instrumentation test. Now it does, after changes in simdjson (https://github.com/lemire/simdjson/issues/186).
* get minify running (api change)
* disable benchmarks when compiling fuzzers
* catch exceptions from the minify fuzzer
* enable repeated corpus creation without recursive inclusion of zip
* remove leftover comment
This creates a "document" class with only user-facing document state (no parser internals).
- document: user-facing document state
- document::iterator: iterator (equivalent of ParsedJsonIterator)
- document::parser: parser state plus a "docked" document we parse into (equivalent of ParsedJson)
Usage:
```c++
auto doc = simdjson::document::parse(buf, len); // less efficient but simplest
```
```c++
simdjson::document::parser parser; // reusable parser
parser.allocate_capacity(len);
simdjson::document* doc = parser.parse(buf, len); // pointer to doc inside parser
doc = parser.parse(buf2, len); // reuses all buffers and overwrites doc; more efficient
```
* initial oss-fuzz friendly build
parts taken from libfmt, which I wrote and have the copyright to
* fix build error
* add script for building a corpus zip
see https://google.github.io/oss-fuzz/getting-started/new-project-guide/#seed-corpus
* fix zip command
* drop setting the C++ standard
* disable the minify fuzzer, does not pass oss-fuzz check-build test
* fix integer overflow in subnormal_power10
detected by oss-fuzz
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=18714
* invoke the build like oss fuzz does
* document what the scripts are for and how to use them
* add a page about fuzzing
