This issue is not reproducible with the WebDriver shipped by Debian experimental for the very same version of WebKitGTK (2.25.4). I have inspected the patches shipped by both Debian and Fedora versions, as well as the different build options and at first sight I can't see nothing there to explain this different behaviour. Perhaps its related with some compiler bug. The complete build logs, including build flags passed are here: * Fedora: https://kojipkgs.fedoraproject.org/packages/webkit2gtk3/2.25.4/1.fc31/data/logs/x86_64/build.log * Debian: https://buildd.debian.org/status/fetch.php?pkg=webkit2gtk&arch=amd64&ver=2.25.4-1&stamp=1565353274&raw=1 1562779 1 376704 clopez 2019-08-19 12:55:00 -0700 Created attachment 376704 simplified test case to reproduce the issue I'm attaching a simplified test-case to reproduce the issue. To test it do the following: 1) On a terminal open WebKitWebDriver to listen on 127.0.0.1:444 WebKitWebDriver --host=127.0.0.1 --port=4444 2) On another terminal run the attached script. Pass "epiphany" to execute epiphany from the webdriver or pass the path to the minibrowser to execute with the MB. If it works as expected it should print something like: {"value":null}{"value":[{"element-6066-11e4-a52e-4f735466cecf":"node-31A8F3A7-8142-4F75-B80F-538E5208ED28"}]} But on Fedora it always prints: {"value":null}{"value":{"error":"javascript error","message":"Unexpected string literal '/'. Expected ')' to end a compound expression.","stacktrace":""}} 1562800 2 clopez 2019-08-19 14:15:19 -0700 The issue is also reproducible on Fedora 30 with webkit2gtk3-2.24.3-1.fc30 1562868 3 clopez 2019-08-19 17:43:17 -0700 I have hunted down the issue to be caused when WebKitGTK+ is built with python3 instead of python2. Passing "-DPYTHON_EXECUTABLE=/usr/bin/python3" to the build or building on a system that doesn't have python2 (CMake will pick python3 if it can't find python2) causes this problem. The problem is very likely caused by some of the python scripts that are run as part of the build process that generate code. 1563035 4 clopez 2019-08-20 06:05:46 -0700 *** This bug has been marked as a duplicate of bug 194367 *** 376704 2019-08-19 12:55:00 -0700 2019-08-19 12:55:00 -0700 simplified test case to reproduce the issue test-webdriver.sh text/plain 2151 clopez IyEvYmluL2Jhc2gKIwojIFRvIHJ1biB0aGlzIHRlc3QgZmlyc3Qgb3BlbiBXZWJLaXRXZWJEcml2 ZXIgdG8gbGlzdGVuIGluIDEyNy4wLjAuMTo0NDQKIyBFeGFtcGxlOgojeHZmYi1ydW4gV2ViS2l0 V2ViRHJpdmVyIC0taG9zdD0xMjcuMC4wLjEgLS1wb3J0PTQ0NDQKIyBUaGVuIHJ1biB0aGlzIHNj cmlwdCwgaWYgaXQgd29ya3MgaXQgc2hvdWxkIHByaW50IHNvbWV0aGluZyBsaWtlCiMgeyJ2YWx1 ZSI6bnVsbH17InZhbHVlIjpbeyJlbGVtZW50LTYwNjYtMTFlNC1hNTJlLTRmNzM1NDY2Y2VjZiI6 Im5vZGUtNzIzRERDOTAtMzE0RC00NjFCLUFGOUUtMDZDQ0I4RjcwRERBIn1dfQojIEFuZCBObyAi amF2YXNjcmlwdCBlcnJvciIgc2hvdWxkIGJlIGxvZ2dlZC4KIwpNSU5JQlJPV1NFUj0iJHsxfSIK CmlmIFsgIiQjIiAtbmUgMSBdOyB0aGVuCiAgICBlY2hvICJFUlJPUjogaW5jb3JyZWN0IG51bWJl ciBvZiBwYXJhbWV0ZXJzIiAxPiYyCiAgICBlY2hvIDE+JjIKICAgIGVjaG8gIiAgKiBGb3IgTWlu aUJyb3dzZXIgdGVzdCB1c2U6IiAxPiYyCiAgICBlY2hvICIgICAgJHswfSAvcGF0aC90by9NaW5p QnJvd3NlciIgMT4mMgogICAgZWNobyAxPiYyCiAgICBlY2hvICIgICogRm9yIGVwaXBoYW55IHRl c3QgdXNlOiIgMT4mMgogICAgZWNobyAiICAgICR7MH0gZXBpcGhhbnkiIDE+JjIKICAgIGV4aXQg MQpmaQoKTUlOSUJST1dTRVI9IiR7MX0iCgppZiBbWyAiJHtNSU5JQlJPV1NFUn0iID09ICJlcGlw aGFueSIgXV07IHRoZW4KCXNlc3Npb25pZD0iJChjdXJsIC1zIC1YIFBPU1QgaHR0cDovLzEyNy4w LjAuMTo0NDQ0L3Nlc3Npb24gLWQgJ3siY2FwYWJpbGl0aWVzIjogeyJhbHdheXNNYXRjaCI6IHsi YnJvd3Nlck5hbWUiOiAiRXBpcGhhbnkiLCAicGxhdGZvcm1OYW1lIjogIkFOWSIsICJ3ZWJraXRn dGs6YnJvd3Nlck9wdGlvbnMiOiB7ImJpbmFyeSI6ICIvdXNyL2Jpbi9lcGlwaGFueSIsICJhcmdz IjogWyItLWF1dG9tYXRpb24tbW9kZSJdfX19fSd8YXdrIC1GJyInICd7cHJpbnQgJDZ9JykiCmVs c2UKCWlmICEgdGVzdCAteCAiJHtNSU5JQlJPV1NFUn0iOyB0aGVuCgkJZWNobyAiRVJST1I6IENh bid0IGZpbmQgdGhlIGV4ZWN1dGFibGUgbWluaWJyb3dzZXIgYXQgJHtNSU5JQlJPV1NFUn0iIDE+ JjIKCQlleGl0IDEKCWZpCglzZXNzaW9uaWQ9IiQoY3VybCAtcyAtWCBQT1NUIGh0dHA6Ly8xMjcu MC4wLjE6NDQ0NC9zZXNzaW9uIC1kICd7ImNhcGFiaWxpdGllcyI6IHsiYWx3YXlzTWF0Y2giOiB7 ImJyb3dzZXJOYW1lIjogIk1pbmlCcm93c2VyIiwgInBsYXRmb3JtTmFtZSI6ICJBTlkiLCAid2Vi a2l0Z3RrOmJyb3dzZXJPcHRpb25zIjogeyJiaW5hcnkiOiAiJyR7TUlOSUJST1dTRVJ9JyIsICJh cmdzIjogWyItLWF1dG9tYXRpb24iXX19fX0nfGF3ayAtRiciJyAne3ByaW50ICQ2fScpIgpmaQpj dXJsIC1zIC1YIFBPU1QgImh0dHA6Ly8xMjcuMC4wLjE6NDQ0NC9zZXNzaW9uLyR7c2Vzc2lvbmlk fS91cmwiIC1kICd7InVybCI6ICJodHRwOi8vdzNjLXRlc3Qub3JnL2luZnJhc3RydWN0dXJlL3Rl c3Rkcml2ZXIvYWN0aW9ucy9lbGVtZW50VGltaW5nLmh0bWwifScKY3VybCAtcyAtWCBQT1NUICJo dHRwOi8vMTI3LjAuMC4xOjQ0NDQvc2Vzc2lvbi8ke3Nlc3Npb25pZH0vZWxlbWVudHMiIC1kICd7 InVzaW5nIjogImNzcyBzZWxlY3RvciIsICJ2YWx1ZSI6ICIjdGVzdDEifScKZWNobwplY2hvICIt LS0tLS0tLS0tLS0tLSIKZWNobyAiVGVzdCBmaW5pc2hlZCIKZWNobyAiLS0tLS0tLS0tLS0tLS0i CmVjaG8gIlRoaXMgdGVzdCBoYXMgcGFzc2VkIGlmIF9ub18gXCJqYXZhc2NyaXB0IGVycm9yXCIg aGFzIGJlZW4gbG9nZ2VkIGFib3ZlIiAKZWNobyAiQW5kIGlmIGEgc3RyaW5nIHNpbWlsYXIgKFVJ RHMgd2lsbCBiZSBkaWZmZXJlbnQpIGhhcyBiZWVuIGxvZ2dlZCBhYm92ZSB0byB0aGlzIG9uZSBi ZWxvdyIKZWNobyAiRXhhbXBsZToge1widmFsdWVcIjpudWxsfXtcInZhbHVlXCI6W3tcImVsZW1l bnQtNjA2Ni0xMWU0LWE1MmUtNGY3MzU0NjZjZWNmXCI6XCJub2RlLTcyM0REQzkwLTMxNEQtNDYx Qi1BRjlFLTA2Q0NCOEY3MEREQVwifV19IgplY2hvICJUbyBydW4gYWdhaW4gY2xvc2UgYW5kIHJl LW9wZW4gV2ViS2l0V2ViRHJpdmVyIGluIHRoZSBvdGhlciBzaGVsbCIK
