71d4990c6d Fix Heap-buffer-overflow in GenericVector<int>::size (issue #2298) 
Credit to OSS-Fuzz:
This fixes a security issue which was reported by OSS-Fuzz, see details at
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=13590.

Add also some assertions to catch similar bugs.

b45999088c LSTM char_whitelist/blacklist (6ac2ff0): multi-code chars 
- move decision from ComputeTopN to ContinueContext, where
  it belongs: block context continuations which emit final
  codes translating to disabled unichar_ids.
  (The normal logic for fallback from top2 > top2 > rest
   will apply.)
- pass UNICHARSET refs appropriately

Robert Schubert
6ac2ff083e trying to add tessedit_char_whitelist etc. again: 
- ignore matrix outputs in ComputeTopN if they
  belong to a disabled unichar_id
- pass UNICHARSET refs to check that
- in SetBlackAndWhitelist, also update the unicharset
  of the lstm_recognizer_ instance, if any

Merge pull request #2290 from stweil/libarchive 
Add initial support for traineddata files in standard archive formats
 2019-03-05 17:42:13 +01:00
Stefan Weil
1c7e00611b Add initial support for traineddata files in standard archive formats 
This requires libarchive-dev.

Tesseract can now load traineddata files in any of the archive formats
which are supported by libarchive. Example of a zipped BagIt archive:

    $ unzip -l /usr/local/share/tessdata/zip.traineddata
    Archive:  /usr/local/share/tessdata/zip.traineddata

`combine_tessdata -d` and `combine_tessdata -u` also work.

The traineddata files in the new format can be generated with
standard tools like zip or tar.

More work is needed for other training tools and big endian support.
