Reflector Download Timed Out
Fritzi Schlicker
(this url for example) and repeat a lot (not for every url) and i have to metion that I can access this url by browser and also when I put it in the first line on mirrorlist, it works but reflector returns error
Hey, it is because the download-timeout is set lower then the time it takes to connect to the server, add this flag to reflector " --download-timeout " and set it to a higher number, you can use 60seconds (it is what i use) for example
grateful
the default is 5, in other hand, if it takes more than 5 second to connect to a server, the server is down or I can not connect to it (I'm from Iran, they like to block IPs a lot )
Dont know why but it happens a lot and because of that it takes a lot of time to reflector takes action
I am tethered to my phone so it certainly isn't the greatest connection, but despite all the warnings I get between 1 and 3 MB/s downloads with pacman and no repo/package download failure. That's why to me it feels like there is a certain something specific to reflector which triggers those failures, but I don't know enough to say what.
The community database is 6 MB. The download times out after 5 s. If your average download rate with your connection over 5 seconds is less than 1.2 MB/s then it will time out. This isn't a reflector issue, unless mirrors start blocking requests from reflector due to the number of people misusing the rate sorting.
Thanks for your reply. I was operating under the assumption that the "download timed out" message meant the connection had failed/broken up, but hadn't considered the 5s delay applied to the allotted time to download a file from the servers. But your math checks out and it does explain why only community.db is affected. If pacman has even just a 10s timeout delay, that would explain the difference in behaviour I observed.
So you feel like people abuse the rate sorting functionality? It is enabled in the Archiso reflector config, and I see it as one of the stronger selling points of the software, but I think I can understand what you mean especially in conjunction with ParallelDownloads (which is disabled by default OTOH). What would you recommend people do?
I just installed Endeavour this morning and noticed that the download speed with pacman was very slow and unstable (something around 10.000kb/s and sometimes it just drops to 0b/s) but my connection was actually fine, so i figured out that it might be some kind of mirror problem and tried to use reflector.
Hi, My computer cannot update because of an error: Reflector: reflector: fetching information from failed! when me click update Mirrors . Can anyone support me? Thank you.
Sorry for my english is not good.
Think of reflector-simple as one shop stopping. You set it up once and forget it. This means you will have a static mirror list that never changes ranked according to the options you selected via the button in the welcome app. This is made easier by having the check boxes for number of mirrors, rate (speed), and how long the mirrors refreshed last. This will not change unless you repeat the process manually.
Reflector ships with a reflector.service. The service will run reflector with the parameters specified in /etc/xdg/reflector/reflector.conf. The default options in this file should serve as a good starting point and example.
pacman-mirrorlist is not updated regularly, invoking reflector only because some mirror in some part of the globe was added or removed is not relevant. Use instead the timer-based automation. If you do not want mirrorlist.pacnew to be installed at all, use NoExtract in pacman.conf.
Time-of-flight (TOF) positron emission tomography (PET) detectors improve the signal-to-noise ratio of PET images by limiting the position of the generation of two 511 keV gamma-rays in space using the arrival time difference between the two photons. Unfortunately, bismuth germanate (BGO), widely used in conventional PET detectors, was limited as a TOF PET scintillator due to the relatively slow decay time of the scintillation photons. However, prompt Cerenkov light in BGO has been identified in addition to scintillation photons. Using Cerenkov photons for timing has significantly improved the coincidence timing resolution (CTR) of BGO. Based on this, further research on improving the CTR for a BGO-based TOF PET system is being actively conducted. Wrapping materials for BGO pixels have primarily employed white reflectors to most efficiently collect scintillation light. White reflectors have customarily been used as reflectors for BGO pixels even after Cerenkov light began to be utilized for timing calculations in pixel-level experiments. However, when the arrival-time differences of the two 511 keV annihilations photons were measured with pure Cerenkov radiators, painting the lateral sides of the radiators black can improve CTR by suppressing the reflection of Cerenkov photons. The use of BGO for TOF PET detectors requires simultaneously minimizing scintillation loss for good energy information and suppressing reflected Cerenkov photons for better timing performance. Thus, reflectors for BGO pixels should be optimized for better timing and energy performance. In this study, colored polytetrafluoroethylene (PTFE) tapes with discontinuous reflectance values at specific wavelengths were applied as a BGO reflector. We hypothesized that CTR could be enhanced by selectively suppressing reflected Cerenkov photons with an optimum colored reflector on the BGO pixel while minimizing scintillation photon loss. CTRs were investigated utilizing white and three colors (yellow, red, and green) PTFE tapes as a reflector. In addition, black-painted PTFE tape and enhanced specular reflector film were investigated as reference reflector materials. When 3 3 20 mm3BGO pixels were wrapped with the yellow PTFE reflector, the CTR was significantly improved to 365 5 ps from 403 14 ps measured with the conventional white PTFE reflector. Adequate energy information was still obtained with only 4.1% degradation in light collection compared to the white reflector. Colored reflectors show the possibility to further improve CTR for BGO pixels with optimum reflectance design.

Note: this wiki page is about the Indigo Reflector service for Indigo 6 (left here for legacy purposes). Check here for the reflector docs for the latest Indigo version.
Once on the registration codes list page, you'll see a message to click the Create Reflector link next to your Indigo registration code. Click on that link and you'll switch to the Reflectors page with a form field to enter your reflector name. When you submit that we will create the reflector, activate it, and take you back to the codes page which will show your reflector activated.
You should now see an Activate Reflector button towards the bottom of the dialog. Click that, log in to your reflector account, and select the appropriate reflector. If the reflector you want to use doesn't show in the list of inactive reflectors, contact us with the name of the reflector you're trying to activate and what steps you've performed.
Indigo Touch for iOS is transparently integrated with the Indigo Reflector service. When you use your iOS device (iPhone, iPad, etc.) to connect to Indigo while in your house (and on your local Wi-Fi network), Indigo Touch will automatically retrieve and remember your reflector address. You can press the settings (gear) icon on the top toolbar then find the Reflector item near the bottom to verify that it is working correctly.
Once Indigo automatically detects your reflector address, it will seamlessly change between using the local Bonjour detected address and the remote reflector address. Just launch Indigo Touch and it works, no matter where you are!
Because using a reflector has to bounce all requested files to and from our server, monthly bandwidth usage cannot be unlimited. Reflectors that exceed an average bandwidth of approximately 200 MB per day may have temporary limitations or throttles imposed, but a vast majority of the time bandwidth is not an issue. There are a couple of things that can lead to excessive bandwidth usage. So please consider:
