When creating a CID parser the location of the 'StartData' or '/sfnts' tokens needs to be known. However, the token parser requires that the entire document be in memory and flattening the entire stream into memory is to be avoided. To avoid forcing the entire stream into memory, previously this code would scan through the stream looking for 'StartData' or '/sfnts' as strings. However, these strings could have been in a comment or string token, so the stream would be read into memory up to that point and the parser run to check that these strings were actually tokens. This forced a parser restart from the beginning each time; as a result, data with many 'StartData' non-tokens would take n^2 time to check. * src/cid/cidparse.c (cid_parser_new): Change algorithm to make the initial scan look for the last possible 'StartData' or '/sfnts' string in the stream. The stream is read forward instead of backward as a typical normal CID font will have one 'StartData' toward the beginning of the data and it it much faster to read the data from beginning to end instead of end to beginning. For memory-based fonts the limit is set to the end of the stream since the stream is already in memory. Then the parser is run once to look for 'StartData' or '/sfnts' tokens. If they are found the parser is re-set to reflect this new information. Reported as https://issues.chromium.org/issues/40201695 |

FreeType 2.13.2 =============== Homepage: https://www.freetype.org FreeType is a freely available software library to render fonts. It is written in C, designed to be small, efficient, highly customizable, and portable while capable of producing high-quality output (glyph images) of most vector and bitmap font formats. Please read the `docs/CHANGES` file, it contains IMPORTANT INFORMATION. Read the files `docs/INSTALL*` for installation instructions; see the file `docs/LICENSE.TXT` for the available licenses. For using FreeType's git repository instead of a distribution bundle, please read file `README.git`. Note that you have to actually clone the repository; using a snapshot will not work (in other words, don't use gitlab's 'Download' button). The FreeType 2 API reference is located in directory `docs/reference`; use the file `index.html` as the top entry point. [Please note that currently the search function for locally installed documentation doesn't work due to cross-site scripting issues.] Additional documentation is available as a separate package from our sites. Go to https://download.savannah.gnu.org/releases/freetype/ and download one of the following files. freetype-doc-2.13.2.tar.xz freetype-doc-2.13.2.tar.gz ftdoc2132.zip To view the documentation online, go to https://www.freetype.org/freetype2/docs/ Mailing Lists ------------- The preferred way of communication with the FreeType team is using e-mail lists. general use and discussion: freetype@nongnu.org engine internals, porting, etc.: freetype-devel@nongnu.org announcements: freetype-announce@nongnu.org git repository tracker: freetype-commit@nongnu.org The lists are moderated; see https://www.freetype.org/contact.html how to subscribe. Bugs ---- Please submit bug reports at https://gitlab.freedesktop.org/freetype/freetype/-/issues Alternatively, you might report bugs by e-mail to `freetype-devel@nongnu.org`. Don't forget to send a detailed explanation of the problem -- there is nothing worse than receiving a terse message that only says 'it doesn't work'. Patches ------- For larger changes please provide merge requests at https://gitlab.freedesktop.org/freetype/freetype/-/merge_requests Alternatively, you can send patches to the `freetype-devel@nongnu.org` mailing list -- and thank you in advance for your work on improving FreeType! Details on the process can be found here: https://www.freetype.org/developer.html#patches Enjoy!
