From 5de5fb93e50fe9006221b30ac4a66f1be0db82e7 Mon Sep 17 00:00:00 2001 From: Terry Truong Date: Sun, 11 Sep 2022 14:55:42 +1000 Subject: Add backend unit tests - Add unit testing code in backend/tests/ - Change to snake-case for script/file/directory names - Use os.path.join() instead of '/' - Refactor script code into function defs and a main-guard - Make global vars all-caps Some fixes: - For getting descriptions, some wiki redirects weren't properly resolved - Linked images were sub-optimally propagated - Generation of reduced trees assumed a wiki-id association implied a description - Tilo.py had potential null dereferences by not always using a reduced node set - EOL image downloading didn't properly wait for all threads to end when finishing --- backend/tolData/enwiki/README.md | 63 -------- backend/tolData/enwiki/downloadImgLicenseInfo.py | 147 ------------------ backend/tolData/enwiki/downloadImgs.py | 88 ----------- backend/tolData/enwiki/genDescData.py | 124 --------------- backend/tolData/enwiki/genDumpIndexDb.py | 56 ------- backend/tolData/enwiki/genImgData.py | 186 ----------------------- backend/tolData/enwiki/genPageviewData.py | 62 -------- backend/tolData/enwiki/lookupPage.py | 66 -------- 8 files changed, 792 deletions(-) delete mode 100644 backend/tolData/enwiki/README.md delete mode 100755 backend/tolData/enwiki/downloadImgLicenseInfo.py delete mode 100755 backend/tolData/enwiki/downloadImgs.py delete mode 100755 backend/tolData/enwiki/genDescData.py delete mode 100755 backend/tolData/enwiki/genDumpIndexDb.py delete mode 100755 backend/tolData/enwiki/genImgData.py delete mode 100755 backend/tolData/enwiki/genPageviewData.py delete mode 100755 backend/tolData/enwiki/lookupPage.py (limited to 'backend/tolData/enwiki') diff --git a/backend/tolData/enwiki/README.md b/backend/tolData/enwiki/README.md deleted file mode 100644 index 76f9ee5..0000000 --- a/backend/tolData/enwiki/README.md +++ /dev/null @@ -1,63 +0,0 @@ -This directory holds files obtained/derived from [English Wikipedia](https://en.wikipedia.org/wiki/Main_Page). - -# Downloaded Files -- enwiki-20220501-pages-articles-multistream.xml.bz2
