I have simple-page site on PHP, where users can upload file (stl-model).
At first I was use for upload JS FormData. It's work in Chrome and Firefox, but Safari iOS sometimes send file with size = 0 bytes.
JS console.log show, that file size 718120 bytes before send. PHP debug mode show that global $ _FILE exists and file name is true, but file is empty:
(
[name] => TRRSExtenderMount.stl
[type] => application / octet-stream
[tmp_name] => / tmp / phphDceFc
[error] => 0
[size] => 0
)
The error with size 0 repeats from time to time.
What I tried:
checked phpinfo post_max_size, upload_max_filesize
tested on different devices (all with 13.3.1 iOS)
tested with different stl-files and file-size (from 0.5mb to 16mb)
tested with 3g, 4g and wi-fi
checked slow upload speed: check file size, wait 10 seconds and check it again
changed input form for standart HTML with POST method without JS
But the error was repeated again. What am I doing wrong?
So, I fixed this problem. May be my experience can help somebody:
I reproduced that error returns when you repeat Ajax call 2 min later that first call if you don't reload page.
I noticed File object attribute "lastModified" always equal to file creation date. So browser may be used Formdata from cache. I added next code to always send "new" file:
this.trueFile = new File([this.originalFile], 'file-name.stl', {lastModified: new Date()});
After that the error changed: second Ajax call (after 2 min) crashed on timeout and returned next message:
TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode
Next step I found this question: Getting TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode , And delete next row:
dataType: 'json' from my code. And it helped.

I manually open up the Chrome browser and go to 'https://www.google.com/' and hit F12 to go to developer tools. I then go to Console and type in localStorage.key(0) to get the key of the first item in local storage and I get 'whatever'.
However, when I run the following test code the returned value in firstKey is Empty.
Sub GetLocalStorage()
Dim driverGoogle As Object
Dim firstKey As Variant
Set driverGoogle = CreateObject("Selenium.Chromedriver")
driverGoogle.Get "https://www.google.com/"
driverGoogle.Window.SetSize 1800, 1050
firstKey = driverGoogle.ExecuteScript("localStorage.key(0);")
End Sub
I even changed localStorage.key(0) to incorrect localStorage.aaakey(0) make sure ExecuteScript was actually executing and sure enough Selenium threw an error.
So, how to get Local Storage key/values?
You have to add delay to let the site loaded.
Currently you are trying to apply driverGoogle.ExecuteScript("localStorage.key(0);") script immediately after sending the URL to the web driver while the page just starting loading.
The ExecuteScript string needed the 'return' instruction. Once added everything works fine.
firstKey = driverGoogle.ExecuteScript("return localStorage.key(0);")
I get this error in my log files every time a cache file doesn't exist it seems. On the first page load, I always get this error
[message] => filemtime(): stat failed for [...]/runtime/cache/my/myapp03eab921185f7b68bbca50d8debc0dda.bin
[file] => [...]/vendor/yiisoft/yii2/caching/FileCache.php
[line] => 113
It doesn't happen anymore on next page loads but that one time is really annoying since the slack bot watcher is spamming our channel with this useless warning. Is there a way to avoid that, or is it a permission problem?
The "runtime", "cache" and "my" folders all have 775.
Update
Turns out the issue is that I'm using error_get_last() that is also getting warning-level errors. So it's a different issue entirely, not Yii-related
Make sure that you don't have enabled scream in your php.ini. Warnings from this filemtime() call should be suppressed by # operator, but scream setting can override this operator and generate warning anyway.
if (#filemtime($cacheFile) > time()) {
// ...
}
You must be getting this in PHP 7.1. try to run this with PHP 5.5 and see if you are getting the same error.
To reproduce you need to delete all files from runtime/cache directory
Then start app again(reload page) and look into runtime/cache. It is empty
Yii2 doesn't make cache again
Got same issue in Yii. The error was on the same string (FileCache.php:113)
if (#filemtime($cacheFile) > time()) {...
In my case reason was that my custom php error handler (heir
of the class yii\base\ErrorHandler) didn't check if
error type need to be handled according error_reporting().
Custom handlers allways gets every error, even muted by Error Control operator (#)
https://www.php.net/manual/en/function.set-error-handler.php
error_reporting() settings will have no effect and your error handler will be called regardless
I fetched http://book.flypeach.com/default.aspx?ao=B2CZHTW&ori=TPE&des=KIX&dep=2015-06-12-undefined-undefined&adt=1&chd=0&inf=0&langculture=zh-TW&bLFF=false by driver.current_url
However I got timeout error by this code
wait = Selenium::WebDriver::Wait.new(:timeout => 10) # seconds
wait.until { #driver.find_element(:css => "div.WrapperFlightDate") }
But I can see the css attributes div.WrapperFlightDate was truly exsiting in the page_source,
How could it happen ?
When I opened given link and trying to see given class in source code(ctrl + u),I didn't find given class.May be page was not loaded properly.
I refreshed page and right click on page -> View Page Source option then got this class in source code.Even I also ran this successfully in FF.
I also surprised why I didn't see correct source code first time.
You also try same,hope so you also get correct code now :).
I'm testing using RApache as an SSE (Server Sent Events) and similar (long poll, comet, etc.) back-end. I seem to be stuck on how to flush my output. Is it possible?
Here is my test R script:
setContentType("text/plain")
repeat{
cat(format(Sys.time()),"\n")
#sendBin(paste(format(Sys.time()),"\n"))
flush(stdout())
Sys.sleep(1)
}
My Rapache.conf entry is:
<Location /rtest/sse>
Options -MultiViews
SetHandler r-handler
RFileHandler /var/www/local/rtest/sse.r
</Location>
And I test it using either wget or curl:
wget -O - http://localhost/rtest/sse
curl http://localhost/rtest/sse
Both just sit there, meaning nothing is being sent.
Using sendBin() made no change, and neither did using flush().
If I change repeat to for(i in 1:5) then it sits there for 5 seconds and then shows 5 timestamps (spaced one second apart). So, I believe everything else is working fine and this is purely a buffering issue.
UPDATE: Looking at this with fresh eyes after 5 months, I think I could have described the problem more clearly: the problem is that RApache appears to be buffering all the output, and not sending anything until the R script exits. To be useful for streaming it has to send data out of Apache and on to the client each time flush() is called, i.e. while the R script is still running.
So, my question is: is there a way to get RApache to behave like that?
UPDATE 2 I tried adding flush.console() before or after the flush(stdout()) but no difference. I also tried setStatus(status=200L) at the top. And I tried SERVER$no_cache=T;SERVER$no_local_copy=T; at the top of the script. Again it made no difference. (Yes, none of those should have helped, but it never hurts to try!)
Here is a link to how PHP implements flush when it is running as an Apache module:
http://git.php.net/?p=php-src.git;a=blob;f=sapi/apache2handler/sapi_apache2.c#l290
I think the key point is that there is a call to ap_rflush(r). I'm guessing that RApache is not making the ap_rflush() call.
You are passing the wrong MIME type. Try changing with
setContentType("text/event-stream")
EDIT1:
this is the attempt, (still unsuccessful) I mentioned in the comment below, to implement SSE in Rook.
<%
res$header('Content-Type', 'text/event-stream')
res$header('Cache-Control', 'no-cache')
res$header('Connection', 'keep-alive')
A <- 1
sendMessage <- function(){
while(A<=4){
cat("id: ", Sys.time(), "\n", "data: hello\n\n", sep="")
A <- A+1
flush(stdout())
Sys.sleep(1)
}
}
-%>
<% sendMessage() %>
the while loop condition was supposed to be always TRUE but I'm having your same problem so I had to do a finite loop...
The good new is I DO have data reaching the browser. I can tell by looking, in developer tools, at the Content-Length in the Response Header section. it says 114 for the above code and you change, say, "Hello" in "Hello!" it'll say 118.
The js code is: (you'll need JQuery as well)
$(document).ready(function(){
$("button").click(function(){
var source = new EventSource("../R/sse.Rhtml");
source.onopen = function(event){
console.log("readyState: " + source.readyState);
}
source.onmessage = function(event){
$("#div").append(event.data);
};
source.onerror = function(event){
console.log(event);
};
});
});
So, in essence
1) The connection is open (readyState 1)
2) Buffering is still there
3) Data (after buffering) reaches the browser but an error happens in receiving them properly.
EIDT2:
it's interesting to note that brew()ing the above .Rhtml file the output is not buffered. There must be a configuration the in the web server (both the R internal and Apache) that buffer the data flows.
As a side note, flush is not even needed, cat's output defaults to stout(). So the options are:
Web server configuration
The R equivalent of the PHP ob_flush(); which is always used in any PHP implementation I've seen. this is example
So our app is set up like the standard left frame with the tree, right frame has the main content (loaded from clicking the tree).
Our web app inconsistently displays a blank page in the main frame in Firefox. By inconsistent I mean everyday for a few, rarely for others, never for most. Once we get this, going to any other page through our tree results in a blank page. We found that deleting the "aTreeSaveStateCookie" restores normal operation. "aTree" is the name of our Div. I found "SaveStateCookie" strings in dijit/Tree.js.
This also happens in IE, except I would get a browser error page which I can't recall right now. I would then delete the only cookie I could find for our app (not sure how to do the Firefox steps in IE)
Any ideas on why this would happen?

In my case, I don't recall ever changing browser settings around Private Data.
Please check to see if the response code is 413 (413 = request entity too large), usually this happens when the cookie(s) used to store the tree(s) expansion state (aTreeSaveStateCookie) exceed(s) the maximum request size for your server
You could try increasing the maximum request size (follow instructions for your specific web app server) or at least display a meaningful error message like "please clear your browser cache" when the 413 error code is encountered
If the persist property is set to a truthy value, dijit.Tree is persisting its state to remember which nodes were expanded, and expand them after a page reload. If you need to persist the tree state in presence of a very large data structure, I recommend overriding Tree to use localStorage instead of dojo.cookie.
This is Dojo v. 1.9, but similar changes can be done to the non-AMD version 1.3
_saveExpandedNodes: function(){
if(this.persist && this.cookieName){
var ary = [];
for(var id in this._openedNodes){
ary.push(id);
}
// Was:
// cookie(this.cookieName, ary.join(","), {expires: 365});
localStorage.setItem(this.cookieName, ary.join(","));
}
},
And:
_initState: function(){
// summary:
// Load in which nodes should be opened automatically
this._openedNodes = {};
if(this.persist && this.cookieName){
// Was:
// var oreo = cookie(this.cookieName);
var oreo = localStorage.getItem(this.cookieName);
if(oreo){
array.forEach(oreo.split(','), function(item){
this._openedNodes[item] = true;
}, this);
}
}
},
