"I get error message: try to reload" is far too fuzzy, I'm sure there was a more specific error displayed. tex commented Oct 24, 2015 Contributor Sorry. This is the error: It happens when I suspend laptop and then resume. QuteBrowser thinks that network is down even though it is up and working. I'm on wifi. The-Compiler changed the title from Cannot load web page after suspend:resume to "Network is disabled" error with Qt 5.5.1 after suspend/resume Oct 25, 2015 The-Compiler commented Oct 25, 2015 Collaborator I've also seen this once, but I can't consistently reproduce it. It seems like some Qt issue introduced with Qt 5.5.1, as I've never heard about this error before... The-Compiler added qt report upstream priority: 1 - middle labels Oct 25, 2015 cptMikky commented Oct 29, 2015 I can consistently reproduce this behaviour by following these steps: 1. Internet is accessible: open an arbitrary webpage in a tab. Page loads. 2. disconnect the network. refresh tab: network disabled 3. reconnect the network. Internet is accessible. Refresh tab: network disabled 4. open a page in a new window or tab: page loads 5. refres the "old" tab: network (still) disabled It seems that once a tab detects a network down situation, it will consider the network inaccessible indefinitely, not even trying to check whether anything changed.

Restart of Qutebrowser solves the problem. But would be great if we can get a solution for this. The-Compiler commented Nov 19, 2015 Collaborator Nothing I can do. Using gC to clone the tab (or opening a new tab in general) works as well. I built the 5.6 beta in the meantime after some trouble, but didn't try it yet. I'm pretty confident it's solved there though, as other projects with the same issue have confirmed that already. The-Compiler commented Jan 7, 2016 Collaborator Maybe qutebrowser could auto-create a new QNAM (or clone the tab and close the broken one) when this happens. NoSuck commented Jan 12, 2016 As a constantly roaming qutebrowser user, this issue has affected me a great deal... until today. The network access error no longer appears, and pages reload as expected. I will report back later, when I know more. NoSuck referenced this issue Jan 17, 2016 No internet after standby/hybernate #1233 Closed The-Compiler removed the report upstream label Mar 20, 2016 craftyguy commented Mar 21, 2016 Contributor I upgraded to qt5.6 (Arch, it's in "testing" repo) and I can still reproduce this behavior :( Ram-Z commented Mar 21, 2016 Contributor I experience this as well (sporadically), but it seems to be bound to each tab. Opening new tabs will work, but reloading the tab will not. tex commented Mar 21, 2016 Contributor @Ram-Z I see the same. The-Compiler commented Mar 21, 2016 Collaborator Yeah, it's the QNetworkAccessManager class which gets into some invalid state, and each tab has its own one. This will be gone with QtWebEngine (as it doesn't use the Qt network stack), but I might try implementing a workaround which just automatically clones the tab ( gC ) and closes the "broken" one when this happens. Ram-Z commented Mar 21, 2016 Contributor Cloning tabs would be nice. Currently I just reopen the url in a new tab ( gO ), but unfortunately this does not copy the history. It's a nice feature on it's own, not only as a workaround for this.

Whats weird is that tab-clone dosent work in this situation (but tab-clone does fix the issue if I switch from wired -> wireless, suspend/resume, or switch wireless networks). If someone thinks this is different, I'll create a new issue and try to find more debug info. Also, qt5.6 seems to be in the arch stable repos, but pyqt seems to still be at 5.5.1. qutebrowser v0.5.1 Git commit: CPython: 3.5.1 Qt: 5.5.1, runtime: 5.6.0 PyQt: 5.5.1 Style: QFusionStyle Desktop: /usr/share/xsessions/bspwm sip: 4.18.dev1603251537 colorlog: yes colorama: 0.3.7 pypeg2: 2.15 jinja2: 2.8 pygments: 2.1.3 yaml: 3.11 cssutils: 1.0.1 $Id$ pdf.js: 1.3.91 Webkit: 538.1 Harfbuzz: old SSL: OpenSSL 1.0.2g 1 Mar 2016 Frozen: False Platform: Linux-4.4.5-1-ARCH-x86_64-with-arch, 64bit OS Version: --- /etc/arch-release --- --- /etc/os-release --- NAME="Arch Linux" ID=arch PRETTY_NAME="Arch Linux" ANSI_COLOR="0;36" HOME_URL="https://www.archlinux.org/" SUPPORT_URL="https://bbs.archlinux.org/" BUG_REPORT_URL="https://bugs.archlinux.org/" craftyguy commented Mar 29, 2016 Contributor @jgkamat Interesting, I wonder if rebuilding pyqt5.5 against qt5.6 would resolve this issue for you. I filed this bug last night to (hopefully) have pyqt rebuilt since that resolved a different issue I was experiencing due to qt5.6 hitting stable on Arch: https://bugs.archlinux.org/task/48734 The-Compiler commented Mar 29, 2016 Collaborator I think I'm seeing a variant of this issue occasionally when I'm on my school wireless network (maybe when I switch APs on the same network?) without any suspend/resume. Whats weird is that tab- clone dosent work in this situation (but tab-clone does fix the issue if I switch from wired -> wireless, suspend/resume, or switch wireless networks). If someone thinks this is different, I'll create a new issue and try to find more debug info. I'm guessing it's an eduroam network? I think I've heard of other people having trouble as well where :tab- clone didn't help either. Unfortunately, there really isn't much I can do (except recommending :restart as a workaround in your case) until Qt fixes this - at least for QtWebKit... Did I already throw an obligatory "QtWebEngine will fix all of your problems" at you? Also, qt5.6 seems to be in the arch stable repos, but pyqt seems to still be at 5.5.1. That's expected - a 5.5 PyQt should run with a 5.6 Qt just fine, and PyQt 5.6 hasn't been released yet. This is because Qt aims to keep binary compatibility with new minor releases. (except they accidentally[?] didn't for QtTest with Qt 5.6, which is why you'll get into trouble currently when trying to run the testsuite on Arch) 1 jgkamat commented Mar 29, 2016 Collaborator I'm not on an eduroam network (but my school has a lot of nonstandard things as far as I'm aware).

Contents 1 Avendesora Documentation, Release 1.21.1 2 Contents CHAPTER 1 What is Avendesora? Avendesora holds all of your account information. In addition to the username and password, it holds any account information you might want such as account numbers, PINs, verbal passwords, one-time passwords, security questions, URLs, email addresses, phone numbers, etc. Avendesora is a secure repository for all of this information, using GPG to keep the information safe. Account secrets, such as passwords and such can either be saved, as with password vaults, or they can be generated by Avendesora. Generation is quite flexible and is generally preferred as it makes the secrets extremely hard to predict, in most cases eliminating the risk they could be cracked. Avendesora generates secrets from a random seed. The seed can be shared with a collaborator, and once shared, either collaborator can create new shared passwords. You can query Avendesora directly from the command line. When doing so you can either display account information or copy it to the clipboard. You can also configure a hot-key to run Avendesora, in which case it determines which information is needed from context and then fills it into the active application.

Become a sponsor to The-Compiler Florian Bruhin The-Compiler Winterthur, Switzerland About me Hi! I'm Florian Bruhin and the main developer of the qutebrowser project. I recently finished my Bachelor of Science and am now only employed ~16h per week. This means I can now spend a considerable amount of time on my passion: Working on open- source/free software. I'm currently founding a company for some additional freelancing work, but my main goal is to work on what I enjoy and find important - which means mostly qutebrowser! I also contribute to other projects I use often: I'm one of the maintainers of pytest as well as various plugins. I'm involved in the herbstluftwm window manager and hosting its website and other infrastructure. About qutebrowser A keyboard-driven, vim-like browser based on PyQt5 and Qt. In late 2013, I started qutebrowser. After it gained a bigger userbase than I had initially expected, I worked full-time on it for some months, supported by crowdfundings (2016 and 2017). This allowed me to invest a lot of time into qutebrowser and implement major new features. During my studies, it became clear that qutebrowser grew into much more than just a hobby: Even the minimum maintenance work needed to keep things running filled up the free time I was able to invest. Now that my studies are finished, I'd like to pick up pace again by working on qutebrowser part-time.

Basic goals and principles of this system: • Naturalness – Remove the border between mind and matter: everything important should be as few keypresses as possible away from you, and you shouldn’t have to think about what you’re doing. Immersion. • Economy – Programs should be simple and light on system resources and highly extensible. Because of this, many are terminal or small ncurses programs that have all the magic inside of them. • Keyboard/vim-centrality – All terminal programs (and other programs) use vim keys when possible. Your hands never need leave the home row or thereabout. General keyboard changes • Capslock is a useless key in high quality space. It’s now remapped. If you press it alone, it will function as escape, making vimcraft much more natural, but you can also hold it down and it will act as another Windows/super/mod key. • The menu button (usually between the right Alt and Ctrl) is an alternative Super/Mod button.

Therefore, researching flaky UI tests can help web and more diverse running conditions than traditional unit tests. and mobile UI developers by providing insights on effective In addition, UI tests tend to be more complex and resource- detection and prevention methods. heavy, making them unsuited for detection techniques involving rerunning test suites multiple times. To further investigate flaky UI tests, we collect and analyze In this paper, we perform a study on flaky UI tests. We analyze 235 real-world flaky UI test examples found in popular web 235 flaky UI test samples found in 62 projects from both web and and Android mobile projects. For each flaky test example, we Android environments. We identify the common underlying root inspect commit descriptions, issue reports, reported causes, causes of flakiness in the UI tests, the strategies used to manifest the flaky behavior, and the fixing strategies used to remedy flaky and changed code.
