d901 | train | Just use TRY_TO_DATE, it will return NULL for values where it can't parse the input.
A: If you are certain that all of your values other than NULLs are of the string 'yyyymmdd' then the following will work in snowflake.
TO_DATE(TO_CHAR(datekey),'yyyymmdd')
A: Sounds like some of your col4 entries are NULL or empty strings. Try maybe
... FROM df_old WHERE col4 ~ '[0-9]{8}'
to select only valid inputs. To be clear, if you give the format as 'YYYYMMDD' (you should use uppercase) an entry in col4 has to look like '20190522'.
A: All dates are stored in an internal format.
You cannot influence how a date is STORED. However you have it format it the way you want when you pull the data from the database via query.
A: I was able to resolve by the following:
CREATE OR REPLACE TABLE df_new
AS SELECT
,col1 AS NAME
,col2 AS first_name
,col3 AS last_name
,CASE WHEN "col4" = '' then NULL ELSE TO_DATE(col4, 'YYYYMMDD') AS date
FROM df_old
A: I resolved the issue as follows:
CREATE OR REPLACE TABLE df_new

col1 AS NAME
,col2 AS first_name

d902 | train | The keyword for your case is 'Service Instance'
You can create a service instance of database server within the environment specific for your application and bind it via application manifest.
e.g.
cf create-service rabbitmq small-plan myapplication-rabbitmq-instance
As long as you have a binding to myapplication-rabbitmq-instance in your application manifest it would be preserved/be the same between application deployments within this space.
e.g. in your application manifest:
---
...
services:
- myapplication-rabbitmq-instance

d904 | train | For starters in the code there is no overloaded functions. The declaration of update in the derived class hides the declaration of the function with the same name in the base class.
As the member function add is declared in the base class then the name of the function update also is searched in the base class.
Declare the function update as a virtual function.
class Hand
{
public:
// ...
virtual void update();
};
class StandHand : public Hand
{
public:
// ///
void update() override;
};
A: There are two issues in your code, first void update(); in the base class needs to be declared virtual, so that compiler will know that derived classes might override it and use it.
virtual void update();
// add "=0;" if there is no base version of update()
And in the derived class write
void update() override;
//override is unnecessary but recommended
//it verifies that you do indeed overload a method from a base class
Second problem, you cannot call methods from derived class in constructor of its base class. What happens is that calling virtual base method results in calling the base version instead of the derived version. Think of it: the derived object isn't constructed yet but you already call one of its methods? It doesn't make any sense. | unknown | |
d905 | train | When you remove the option at i, you're shuffling all the other options down; so now, the next option is at i. But then because you're using a for loop, you're incrementing i — and you never looked at the option after the option you removed.
Instead, use a while loop and only increment i if you don't remove the option.
var selectobject = document.getElementById("os0"); //this is the select
var i = 0;
while (i < selectobject.length) {
if (selectobject.options[i].value != <?php echo $people; ?> ){
selectobject.remove(i);
alert(i);
} else {
++i;
}
}
Live Example using 3 (and without the alert):
var people = 3;
var selectobject = document.getElementById("os0"); //this is the select
var i = 0;
while (i < selectobject.length) {
if (selectobject.options[i].value != people){
selectobject.remove(i);
} else {
++i;
}
}
<select name="os0" id="os0">
<option id="1" value="1">1 €123,97 EUR</option>
<option id="2" value="2">2 €249,94 EUR</option>
<option id="3" value="3">3 €371,91 EUR</option>
<option id="4" value="4">4 €495,88 EUR</option>
<option id="5" value="5">5 €619,85 EUR</option>
<option id="6" value="6">6 €743,82 EUR</option>
<option id="7" value="7">7 €867,79 EUR</option>
<option id="8" value="8">8 €991,76 EUR</option>
<option id="9" value="9">9 €1.115,73 EUR</option>
<option id="10" value="10">10 €1.239,70 EUR</option>
</select>
A: When you remove items while iterating over them, the element currently processed in i will be offset each time an item is removed.
If you remove them in reverse you shouldn't have the issue. See example below if element with value 9 was desired.
document.addEventListener('DOMContentLoaded', function() {
var selectobject = document.getElementById("os0"); //this is the select
for (var i = selectobject.length - 1; i >= 0; i--) {
if (selectobject.options[i].value != 9) {

d907 | train | Use slash at the beginning like
<img src="/images/header.jpg" width="790" height="228" alt="" />
You can also use image_tag (which is better for routing)
image_tag('/images/header.jpg', array('alt' => __("My image")))
In the array with parameters you can add all HTML attributes like width, height, alt etc.
P.S. IT's not easy to learn Symfony. You need much more time
A: If you don't want a fully PHP generated image tag but just want the correct path to your image, you can do :
<img src="<?php echo image_path('header.jpg'); ?>"> width="700" height="228" alt="" />
Notice that the path passed to image_path excludes the /images part as this is automatically determined and created for you by Symfony, all you need to supply is the path to the file relative to the image directory.
You can also get to your image directory a little more crudely using
sfConfig::get('sf_web_dir')."/images/path/to/your/image.jpg"
It should be noted that using image_tag has a much larger performance cost attached to it than using image_path as noted on thirtyseven's blog

A: The easiest way is pass it to a service in the first page, and pick it from same service on the next page.
First Create a service and then declare a public variable inside your service like this

then go down and declare a function to always change this variable anytime
changeData(result){
this.result = result;
}
Second
go to the page where you want to pass the data and pass it like below,
using the name of the service and the public variable.
this.util.changeData(data);
note: data here is the data you want to pass
Thirdly
you can pick the data from anywhere on your app,

d914 | train | Sure there is. This is how all the 3rd party packages we are all using did.
The formal pypa explain how to do it here.
Basically you need to package your project to a wheel file and upload it to the pypi repository. To do this you need to declare (mainly in setup.py), what is your package name, version, which sub-packages you want to pack to the wheel etc..
A: If your packages are required for a particular project, it is straightforward to contain them in the Git repository. You can put them in the directory named wheelhouse, which comes from the name of the previous default directory created by pip wheel.
If you put the private package foo in the wheelhouse, you can install as follows:
pip install foo -f wheelhouse | unknown | |
d915 | train | Depending on the testing framework you are using junit or testng you can use the concept of soft assertion. Basically it will collect all the errors and throw an assertion error if something is amiss.
To fail a scenario you just need an assertion to fail, no need to set the status of the scenario. Cucumber will take care of that if an assertion fails.
For testng you can use the SoftAssert class - http://testng.org/javadocs/org/testng/asserts/SoftAssert.html You will get plenty tutorials for this. Call to doAssert will trigger of the verification of all stored assertions.
For junit you can use the ErrorCollector Rule class -
http://junit.org/junit4/javadoc/4.12/org/junit/rules/ErrorCollector.htmlenter link description here As cucumber does not support @Rule annotation, you need to inherit from this class and override the verify property to change its modifier to public in place of protected. Create an instance of the new class and add the assertions. Call to verify method will start the verification.
A: QAF provides assertion and verification concepts, where on assertion failure scenario exited with failed status and in case of verification scenario continue for next step and final status of step/scenario is failed if one or more verification failure.
You also can set step status failure using step listener which result in test failure. With use of step listener, you also can continue even step failure by converting exception to verification failure.
A: It is not a good idea to continue executing steps after a step failure because a step failure can leave the World with an invariant violation. A better strategy is to increase the granularity of your scenarios. Instead of writing a single scenario with several "Then" statements, use a list of examples to separately test each postconditions. Sometimes a scenario outline and list of examples can consolidate similar stories. https://cucumber.io/docs/reference#scenario-outline
There is some discussion about adding a feature to tag certain steps to continue after failure. https://github.com/cucumber/cucumber/issues/79
There are some other approaches to continuing through scenario steps after a failure here: continue running cucumber steps after a failure | unknown | |
d916 | train | Just a partial idea.
The DFT is separable. It is always computed by first applying the FFT algorithm to rows of the image, then to the columns of the result (or the other way around, the order doesn't matter).
If you want only an ROI of the output, in the second step you only need to process the columns that fall within the ROI.
I don't think you'll find a way to compute only a subset of frequencies along each 1D row/column. That would likely entail hacking your own FFT, which will likely be more computationally expensive than using the one in IPP or FFTW. | unknown | |

repeating notes I left as a comment on the question, because I'm not sure there was enough emphasis placed on these points:
"I don't think the slowness is due to three separate statements."
"It looks like the statements have the potential to churn through a lot of rows, even with appropriate indexes defined."
"Use EXPLAIN to see the execution plan, and ensure suitable indexes are being used, ..."
answer
The DELETE statement can't be combined with an UPDATE statement. SQL doesn't work like that.
It might be possible to combine the two UPDATE statements, if those are visiting the same rows, and the conditions are the same, and the second UPDATE is not dependent on the preceding UPDATE and DELETE statement.
We see the first UPDATE statement requires a matching row from bidbutler table. The second UPDATE statement has no such requirement.
We notice that the predicates in the WHERE clause are negating the "outerness" of the LEFT JOIN. If the original statements are correctly implemented (and are performing the required operation), then we can eliminate the LEFT keyword.)
We also find a condition a.auctionID=a.auctionID which boils down to a.auctionID IS NOT NULL. We already have other conditions that require a.auctionID to be non-NULL. (Why is that condition included in the statement?)
We also see a condition repeated: b.auc_id=c.auction_id appearing in both the ON clause and the WHERE clause. That condition only needs to be specified once. (Why is it written like that? Maybe something else was intended?)
The first UPDATE statement could be rewritten into the equivalent:
UPDATE auction a
JOIN auc_due_table d
ON d.auction_id = a.auctionID
AND d.auc_due_time = a.total_time
AND d.auc_due_price <> a.auc_final_price
LEFT
JOIN bidbutler b
ON b.auc_id = a.auctionID
AND b.auc_id = d.auction_id
AND b.butler_status <> 0
SET b.butler_status = 0
WHERE a.auc_status = 3
The second UPDATE statement can be rewritten into an equivalent:
UPDATE auction a
JOIN auc_due_table d
ON d.auction_id = a.auctionID
AND d.auc_due_time = a.total_time
AND d.auc_due_price <> a.auc_final_price
SET a.auc_status = 2
WHERE a.auc_status = 3
The difference is the extra outer join to bidbutler table, and the SET clause.
But before we combine these, we need to decipher whether the operations performed in the first UPDATE or the DELETE statement) influence the second UPDATE statement. (If we run these statements in a different order, do we get a different outcome?)
A simple example to illustrate the type of dependency we're trying to uncover:
UPDATE foo SET foo.bar = 1 WHERE foo.bar = 0;
DELETE foo.* FROM foo WHERE foo.bar = 0;
UPDATE foo SET foo.qux = 2 WHERE foo.bar = 1;
In the example, we see that the outcome is (potentially) dependent on the order the statements are executed. The first UPDATE statement will modify the rows that won't be removed by the DELETE. If we were to run the DELETE first, that would remove rows that would have been updated... the order the statements are executed influence the result.
Back to the original statements in the question. We see auc_status column being set, but also a condition on the same column.
If there are no dependencies between the statements, then we could re-write the two UPDATE statements into a single statement:
UPDATE auction a
JOIN auc_due_table d
ON d.auction_id = a.auctionID
AND d.auc_due_time = a.total_time
AND d.auc_due_price <> a.auc_final_price
LEFT
JOIN bidbutler b
ON b.auc_id = a.auctionID
AND b.auc_id = d.auction_id
AND b.butler_status <> 0
SET b.butler_status = 0
, a.auc_status = 2
WHERE a.auc_status = 3 | unknown | |

d923 | train | You'll want to read-up about the offline_access permission.
https://developers.facebook.com/docs/reference/api/permissions/
With this permission, you'll be able to query facebook for information about one of your users even when that user is offline. It gives you a "long living" access token. This token does expire after a while or if the user changes his/her facebook password.

d931 | train | One of the simplest ways to backup a mysql database is by creating a dump file. And that is what mysqldump is for. Please read the documentation for mysqldump.
In its simplest syntax, you can create a dump with the following command:
mysqldump [connection parameters] database_name > dump_file.sql
where the [connection parameters] are those you need to connect your local client to the MySQL server where the database resides.
mysqldump will create a dump file: a plain text file which contains the SQL instructions needed to create and populate the tables of a database. The > character will redirect the output of mysqldump to a file (in this example, dump_file.sql). You can, of course, compress this file to make it more easy to handle.
You can move that file wherever you want.
To restore a dump file:
*
*Create an empty database (let's say restore) in the destination server
*Load the dump:
mysql [connection parameters] restore < dump_file.sql
There are, of course, some other "switches" you can use with mysqldump. I frequently use these:
*
*-d: this wil tell mysqldump to create an "empty" backup: the tables and views will be exported, but without data (useful if all you want is a database "template")
*-R: include the stored routines (procedures and functions) in the dump file
*--delayed-insert: uses insert delayed instead of insert for populating tables

You can include the mysqldump command and any other compression and copy / move command in a batch file.
A: My solution to extract a backup and push it onto Dropbox is as below.
A sample of Ubuntu batch file can be downloaded here.
In brief
*
*Prepare a batch script backup.sh
*Run backup.sh to create a backup version e.g. backup.sql
*Copy backup.sql to Dropbox folder
*Schedule Ubuntu/Windows task to run backup.sh task e.g. every day at night
Detail steps
*
*All about backing up and restoring an MySQL database can be found here.
Back up to compressed file
mysqldump -u [uname] -p [dbname] | gzip -9 > [backupfile.sql.gz]
*How to remote from Windows to execute the 'backup' command can be found here.
plink.exe -ssh -pw -i "Path\to\private-key\key.ppk" -noagent username@server-ip

Create a app
https://www2.dropbox.com/developers/apps
Add an app and choose Dropbox API App. Note the created app key and app secret
Install Dropbox API in Ubuntu; use app key and app secret above
$ wget https://raw.github.com/andreafabrizi/Dropbox-Uploader/master/dropbox_uploader.sh
$ chmod +x dropbox_uploader.sh
Follow the instruction to authorize access for the app e.g.
http://www2.dropbox.com/1/oauth/authorize?oauth_token=XXXXXXX
Test the app if it is working right - should be ok
$ ./dropbox_uploader.sh info
The app is created and a folder associating with it is YourDropbox\Apps\<app name>
Commands to use
List files
$ ./dropbox_uploader.sh list
Upload file
$ ./dropbox_uploader.sh upload <filename> <dropbox location>
e.g.
$ ./dropbox_uploader.sh upload backup.sql .
This will store file backup.sql to YourDropbox\Apps\<app name>\backup.sql
Done
*How to schedule a Ubuntu can be view here using crontab
Call command
sudo crontab -e
Insert a line to run backup.sh script everyday as below
0 0 * * * /home/userName/pathTo/backup.sh
Explaination:
minute (0-59), hour (0-23, 0 = midnight), day (1-31), month (1-12), weekday (0-6, 0 = Sunday), command
Or simply we can use
@daily /home/userName/pathTo/backup.sh

d933 | train | You can leave the Id on the base class and in this use case you have to configure your one-to-one releshinship with Fluent API.
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<ArqAppRole>()
.HasRequired(s => s.Application)
.WithRequiredPrincipal(ad => ad.ArqAppRole);

Fluent API will override your code first. But putting the Id in the base class is a bad practice and you have to find tricks everywhere. Just use the conventional way and use the EF as should be used.

It was due to the flag android:launchMode="singleInstance" on the activity presenting the interstitial.
i think it is an adMob bug, so please check and in case just remove this flag to get interstitial working.
A: I finally figured out the problem. There was no problem; it is by design. The ads load if clicked near the middle but not if clicked near the corners. That's why sometimes they seemed to randomly not click through. Took me a while to figure that out. | unknown | |

d939 | train | In the upcoming jParsec 2.2 release, the API makes it more clear what Terminals does:
http://jparsec.github.io/jparsec/apidocs/org/codehaus/jparsec/Terminals.Builder.html
You cannot even define your keywords without first providing a scanner that defines "words".
The implementation first uses the provided word scanner to find all words, and then identifies the special keywords on the scanned words.
So, why does it do it this way?
*
*If you didn't need case insensitivity, you could have passed the keywords as "operators". Yes, you read it right. One can equally use Terminals.token(op) or Terminals.token(keyword) to get the token level parser of them. What distinguishes operators from keywords is just that keywords are "special" words. Whether they happen to be alphabet characters or other printable characters is just by convention.
*Another way to do it, is to define your word scanner precisely as Parsers.or(Scanners.string("keyword1"), Scanners.string("keyword2"), ...). Then Terminals won't try to tokenize anything else.
*The above assumes that you want to do the 2-phase parsing. But that's optional. Your test shows that you weren't feeding the tokenizer to a token-level parser using Parser.from(tokenizer, delim). If two-phase parsing isn't needed, it can be as simple as: or(stringCaseInsensitive("true"), stringCaseInsensitive("false"))
More on point 3. The 2-phase parsing creates a few extra caveats in jParsec that you don't find in other parser combinators like Haskell's Parsec. In Haskell, a string is no different from a list of character. So there really isn't anything to gain by special casing them. many(char 'x') parses a string just fine.
In Java, String isn't a List or array of char. It would be very inefficient if we take the same approach and box each character into a Character object so that the character level and token level parsers can be unified seamlessly.
Now that explains why we have character level parsers at all. But it's completely optional to use the token level parsers (By that, I mean Terminals, Parser.from(), Parser.lexer() etc).
You could create a fully functional parser with only character-level parsers, a.k.a scanners.
For example: Scanners.string("true").or(Scanners.string("false")).sepEndBy1(delim)
A: From the documentation of Tokenizer#caseInsensitive:
org.codehaus.jparsec.Terminals
public static Terminals caseInsensitive(String[] ops,
String[] keywords)
Returns a Terminals object for lexing and parsing the operators with names specified in
ops, and for lexing and parsing the keywords case insensitively. Keywords and operators
are lexed as Tokens.Fragment with Tokens.Tag.RESERVED tag. Words that are not among
keywords are lexed as Fragment with Tokens.Tag.IDENTIFIER tag. A word is defined as an
alphanumeric string that starts with [_a - zA - Z], with 0 or more [0 - 9_a - zA - Z]
following.
Actually, the result returned by your parser is a Fragment object which is tagged according to its type. In your case, d is tagged as IDENTIFIER which is expected.
It is not clear to me what you want to achieve though. Could you please provide a test case ?
A: http://blog.csdn.net/efijki/article/details/46975979
The above blog post explains how to define your own tag. I know it's in Chinese. You just need to see the code. Especially the withTag() and patchTag() part. | unknown | |
d940 | train | You could use .filter:
_.sample([homephone, altphone].filter(_.identity))
Another way would be:
_.sample([homephone, altphone]) || homephone || altphone;
A: What about:
var phone = (homephone && altphone)? _.sample([homephone, altphone]) : (homephone || altphone);
A: Since you're already using underscore, I would suggest leveraging compact:
var phone = _.sample(_.compact([homephone, altphone]));
This is basically a shortened version of dave's answer, since compact is literally implemented as function(array) { return _.filter(array, _.identity); }.
A: Array literals in JavaScript:
[ 1, 2, 3 ]
...are a way to statically declare which things go in which positions in an array. In other words, when you write the code, you already know where things will go.
In your scenario, the positions are only known dynamically. In other words, you don't know where they'll go until you run the program on a given set of inputs.
So basically what you're asking for is impossible, barring any radical changes to how array literals work in future versions of JS. However, if all you want is to save typing, @dave's answer is pretty nice. I'm mainly just clarifying that array literals by themselves don't have this capability. | unknown | |
d941 | train | Your best bet is to have that attribute's value in a hidden input field somewhere on the page, so you can then read it in with jQuery.
Unforunately, to the best of my knowledge jQuery or javascript does not have access to request, session or application scope variables.
So, if you do something like this:
<input type='hidden' name='${sessionVarName}' value='${sessionVarValue}' id='sessionVar'/>
You can access it after the page loads like this:
$(function(){
var sessionVar = $('#sessionVar').val();
alert(sessionVar);
});
This is the solution I've used when needing to get tomcat session vars into javascript, the method should work for you too.
Hope this helps
A: I suggest u to send a AttributeName which will successfully make u to get the sessionScope Attribute,that will be simple. | unknown | |

d943 | train | Instead of reflection, you could use the EF Core public (and some internal) metadata services to get the key values needed for Find method. For setting the modified values you could use EntityEntry.CurrentValues.SetValues method.
Something like this:
using Microsoft.EntityFrameworkCore.Metadata.Internal;
public static void AddEntities<T>(List<T> entities, DbContext db) where T : class
{
using (db)
{
var set = db.Set<T>();
var entityType = db.Model.FindEntityType(typeof(T));
var primaryKey = entityType.FindPrimaryKey();
var keyValues = new object[primaryKey.Properties.Count];
foreach (T e in entities)
{
for (int i = 0; i < keyValues.Length; i++)
keyValues[i] = primaryKey.Properties[i].GetGetter().GetClrValue(e);
var obj = set.Find(keyValues);
if (obj == null)
{
set.Add(e);
}
else
{
db.Entry(obj).CurrentValues.SetValues(e);
}
}
db.SaveChanges();
}
} | unknown | |
d944 | train | You can do that with convert, with a little help from find so you don't have to write a loop:
find /Users/KanZ/Desktop/Project/Test/ -type f -name "M*.jpg" -exec convert {} -flip {} \;
Explanation:
*
*find /Users/KanZ/Desktop/Project/Test/ - Invoke find tool and specify the base directory to perform the search for files recursively.
*-type f - Find only files
*-name "M*.jpg" - Find only files with names that start with M and end with .jpg
*-exec ... \; - For each such file found, perform the command in ...
*convert {} -flip {} - This is the actual command that flips your images. The {}'s are syntax as part of the find command, they represent where the found files from find would be substituted into. So here we are saying to use convert to flip the images vertically with the -flip option, but keep the file names unchanged.
Alternatively:
You can also do it with a loop and globbing:
for file in /Users/KanZ/Desktop/Project/Test/M*.jpg; do convert "$file" -flip "$file"; done | unknown | |
d945 | train | You don't need combinations at all. What you want looks more like a sliding window.
for i in range(2, 6):
for j in range(len(lst) - i + 1):
print(lst[j:j + i])
A: You can loop over the list as following:
a = [1,2,3,4,5,6]
for i in range(2, len(a)):
for j in range(len(a)-i + 1):
print(a[j:j+i])
print()
The trick here is that a[j:j+i] returns the list from j, up until j+i.
Putting this into a function form:
def continuous(lst, length):
slices = []
for j in range(len(lst)-length + 1):
slices.append(a[j:j+length])
return slices
A: You can loop through the list in the following method
lst = [1, 2, 3, 4, 5 ,6]
def continuous(lst, length):
result = []
for i in range (0, len(lst)-length):
entry = []
for j in range (0, length):
entry.append(lst[i+j])
result.append(entry)
return result
print(continuous(lst, 2))
or if you are just looking to print it line by line
def continuous(lst, length):
for i in range (0, len(lst)-length):
entry = []
for j in range (0, length):
entry.append(lst[i+j])
print(entry) | unknown | |

If you wrap div#drop_zone and all next elements like div#object... with div that has inline-block as display style, then there will be no such disappearing.
<style>
#drop-zone-wrapper {display: inline-block;}

d948 | train | You could consider creating an event and handler to handle the timer ticks and then invoke your check.
public class PresenceMonitor {
private volatile bool _running;
private Timer timer;
private readonly TimeSpan _presenceCheckInterval = TimeSpan.FromMinutes(1);
public PresenceMonitor() {
Tick += OnTick;
}
public void Start() {
if (_running) {
return; //already running
}
// Start the timer
timer = new System.Threading.Timer(_ => {
Tick(this, EventArgs.Empty);//rasie event
}, null, TimeSpan.Zero, _presenceCheckInterval);
}
private event EventHandler Tick = delegate { };
private async void OnTick(object sender, EventArgs args) {
if (_running) {
return;
}
_running = true;
await DoworkAsync();
}
private Task DoworkAsync() {
//...
}
}
A: If I understand correctly your requirements, you can get rid of timer and use asynchronous loop.
But you need make Start method asynchronous too
public class PresenceMonitor
{
private volatile bool _running; // possible not needed "volatile" anymore
private readonly int _presenceCheckInterval = 60000; // Milliseconds
public PresenceMonitor()
{
}
public async Task Start()
{
while (true) // may be use some "exit" logic
{
await CheckAsync();
await Task.Delay(_presenceCheckInterval)
}
}
private async Task CheckAsync()
{
if (_running)
{
return;
}
_running = true;
// await DoworkAsync
}
}
Then you can start monitoring
var monitor = new PresenceMonitor();
await monitor.Start();
You can even start monitoring in synchronous way
var monitor = new PresenceMonitor();
monitor.Start(); // Will start monitoring
But approach above is "dangerous" in the way, that any exception thrown inside CheckAsync method will not be propagated. When you start using async-await be ready to "convert" whole application to support it. | unknown | |

d950 | train | Your expected output /api?invoice=12345&67890&supplier=78326832 is rather bizarre: there's no context where it makes sense to escape some ampersands (at the XML/HTML level) and leave others unescaped.
I think that what you really want is to use URI escaping (not XML escaping) for the first ampersand, that is you want /api?invoice=12345%2667890&supplier=78326832. If you're building the URI using XSLT 2.0 you can achieve this by passing the strings through encode-for-uri() before you concatenate them into the URI.
But you've given so little information about the context of your processing that it's hard to be sure exactly what you want. | unknown | |
d951 | train | First you have to add display: flex; to #Container
#Container{
display: flex;
}
If you want to equally distribute the space between children then you can use flex property as
.item{

}
Above CSS is minimum required styles, rest is for demo
#Container {
display: flex;
margin-top: 1rem;
}
.item {
flex: 1;

justify-content: center;
align-items: center;
padding: 1rem;

<div class="item"> 50 % </div>

flex-wrap: wrap;
margin-bottom: 8px;
}
.item {
flex-grow: 1;
margin: 0 12px;
background: #f1f1f1;
}
Your main issue in the code that you gave, is that you're missing the flex item behaviour. I have just set that the item can grow to fill the space with the flex-grow:1.
A: You can make sure a flex child covers up the space if it can, you can provide flex-grow: 1
#Container {
display:flex;
}
.item {

d952 | train | Use the RODBC package to connect to a MS SQL Server database.
First you need to do some setup. Open the "Data Sources (ODBC)" application. (In Control Panel\System and Security\Administrative Tools, or search under the Start Menu.) Add a User DSN (or a System DSN if you have admin rights and want the connection for all users).
Step 1: Give it a name like MyDataBase and select the server that it lives on. The name shouldn't be more than 32 characters or you'll get a warning.
Step 2: Connection details are the same as you would use in SQL Server.
Step 3: Change the default database to the one that you want to connect to.
Finish and test your connection.
Now you get to use R. It's as easy as
library(RODBC)
channel <- odbcConnect("MyDataBase") #or whatever name you gave
query <- "SELECT * FROM MyTable WHERE x > 10"
results <- sqlQuery(query, channel)
odbcClose(channel)
If you are feeling fancy or hate wizards, you can set up the ODBC connection by writing registry entries. Apologies for the big code chunk.

d953 | train | If this is a long-running process I doubt that using blob storage would add that much overhead, although you don't specify what the tasks are.
On Zudio long-running tasks update Table Storage tables with progress and completion status, and we use polling from the browser to check when a task has finished. In the case of a large result returning to the user, we provide a direct link with a shared access signature to the blob with the completion message, so they can download it directly from storage. We're looking at replacing the polling with SignalR running over Service Bus, and having the worker roles send updates directly to the client, but we haven't started that development work yet so I can't tell you how that will actually work. | unknown | |
d954 | train | The problem is that myMessage.length() is the number of characters in myMessage, whereas numbers.size is the number of integers represented in myMessage.
In your example run, myMessage is "22 12 20 28", which has 11 characters so you are iterating from 0 to 10; but numbers is an array of just four numbers (0 through 3), so numbers[i] will raise this exception for any i greater than 3.
If I'm understanding correctly what you are trying to do, you just need to change this:
for (int i=0; i < myMessage.length(); ){
to this:
for (int i=0; i < numbers.size; ){ | unknown | |
d955 | train | Keep in mind below important points regarding to UITableView
*
*UITableView has inherited property from UIScrollView i.e. UITableView is also below like a UIScrollView so you don't need to take UIScrollView for the specially scroll the UITableView. If you do it behaves weird.
*In cellForRow, you are creating condition with param tableView to outlet typeView & typeView1 by comparing tag which is not a standard format. Because tableView.tag may be changed and gives you wrong output. So try to use below format
if tableView == typeView { }
else { } //tableView == typeView1
Compare UITableView objects with pram tableView.
*cellForRow method returns the cell from the if-else so you don't need to write
return UITableViewCell(style: UITableViewCellStyle.default, reuseIdentifier: "Cell")
If I debug your cellForRow method code then your this above line never executes.
First try this standards and remove your mistake and then post your question and issue you are facing.
Hope my above work helps you.
Edit
Your required output will be like this below image. You don't need to take 2 UItableView and thse tableview in single scrollview. You can do the same with one tableView.

d960 | train | Note: Previous to Delphi 10.4 the mobile compilers used by default 0-based indexing for strings. See Zero-based strings.
Use the Low() and High() intrinsic functions to iterate strings.
The irregularities you are seeing is because of indexing outside of the boundries of the string. When debugging, use overflow and range checking on to detect these kind of errors.
Your code will look like this:
function TJotto.OccurrencesOfChar(const aWord, aChar: string): integer;
var
i: integer;
begin
result := 0;
for i := Low(aWord) to High(aWord) do

d962 | train | You could use separate branches for each feature. I personally use a hierarchy similar to below.
/
|---features
|--- A
|--- B
That would result in /features/A and /features/B branches respectively. That way you could work on your features on separate branches and use main branch as stable version of your application.
After your last edit, I would definitely recommend the solution below.
Or a better solution for entirely different jobs, you could use git-worktree command.
git worktree add [-b <new-branch>] <path> [<the branch/tree you want to base this worktree>]
This is the best I could from what I've understand from your question.
A: For my understanding, you have a main project and a different project which is based on the main, while being significantly different.
If that's the case, I would have different repositories for the two, so to keep them more maintainable.
The main repo will stay as it is, while on the second one we want to add the main repo as a remote origin.
To do that let's first:
*
*Create a new repo at github
*Clone the main repo locally if not done already
You can then add the main repo as a remote origin:
*git remote rename origin upstream
*git remote add origin URL_TO_MAIN_GITHUB_REPO
*git push origin master
Now you can work with it just like any other github repo.
To pull in patches from upstream, simply run git pull upstream master && git push origin master.
To underline I would follow this solution if you have two different projects based on some common changes, as branches works well for features / patches you would then want to merge to master once they are completed.
If, on the other hand, you simply have the same project with different features, then @Deniz da King solution is great. | unknown | |
d963 | train | 127.0.0.1 as an IP address means "this machine". More formally, it's the loopback interface. On your laptop you have a MySQL server running. Your heroku dyno does not, so your connection attempt fails.
You won't be able to connect from your program running on your heroku dyno to your laptop's MySQL server without some network configuration work on your office or home router / firewall. But to begin doing that work you'll need to come up to speed on networking. (Teaching you how is beyond the scope of a Stack Overflow answer.)

A: To change a column to numeric you can use as.numeric(column_name)
Based on the date format in the archiwum_tab_a_2015.csv file, you can change the date column with as.Date(column_name, format = "%Y%m%d")

A: MVC5 comes with Identity instead of the older SimpleMembership and ASP.NET Membership. Identity doesn't use forms auth, hence why what you're doing has no effect.
To log a user in via Identity, first, you need an actual user instance, which you can get by doing something like:
var userManager = new UserManager<ApplicationUser>(context);
var user = userManager.FindByName(username);
Then if you have a valid user (user != null), you need to generate a claims identity for that user via:
var identity = UserManager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);
Finally, you can use that identity to sign the user in:
var authenticationManager = HttpContext.GetOwinContext().Authentication;
authenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = false }, identity);

d966 | train | As markE said set the transform-origin to the center of the image, so something like this:
elem.style.transform-origin = "50% 50%";
elem.style.transform = "rotate("+degrees+"deg)";
You can use -ms- and -webkit- for this in your code too for cross compatability.
Slightly unrelated, I suggest using:
degrees = degrees%360;
instead of your if statement where you wrap from 359 to 1 degrees.
This is because it will work in more general situations, so is less likely to break. For example if you changed the amount of degrees no by +1 but by +10 or -10 it would still wrap correctly between 0 and 360. | unknown | |
d967 | train | By default when Spring encounters a auto wiring field of type Map<String, [type]> it will inject a map of beans of the specific [type]. In your case String. You will not get your configured map.
See: http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#beans-autowired-annotation.
You are basically running into a corner case as you have a map with String as keys. To get your bean you will either have to put an @Qualifier("profileDependentProps") next to the @Autowired or use @Resource("profileDependentProps") instead of @Autowired. | unknown | |

d970 | train | The simple answer to order functions after an event would be to add a single event handler function that runs the 2 functions one after the other.
$("select#myDropdownlist").change(function(){
callFirstFunction();
callSecondAjaxFunction();
}
A: How about putting the contents of the first function in a method:
$("select#myDropdownlist").change(function(){
submitPostFunction1();
}
submitPostFunction1 = function() {
//do function 1 stuff here
}
then in your more specific function - function2:
$("select#myDropdownlist").change(function(){
$("select").unbind();
submitPostFunction1();
//do function 2 stuff
$("select").bind("change", function() {
submitPostFunction1();
})
}
keep in mind that i used $("select") in function 2 because you said it was a more generic call, so that means you wont be using the id in the first function call.
A: Events are not specified to fire in any specific order.
If you want a specific order, you need to either invoke them from a meta handler, or chain them by calling one from the other. The meta handler is more flexible in the long run though.
$("select#myDropdownlist").change(function(){
firstHandler();
secondHandler();

or
function firstHandler() {

function secondHandler() {

Save your Excel data as a csv file (In Excel 2007 using Save As)
Check the saved file using a text editor such as Notepad to see what it actually looks like, i.e. what delimiter was used etc.
Start the MySQL Command Prompt (I usually do this from the MySQL Query Browser – Tools – MySQL Command Line Client to avoid having to enter username and password etc.)
Enter this command:
LOAD DATA LOCAL INFILE ‘C:\\temp\\yourfile.csv’ INTO TABLE database.table FIELDS TERMINATED BY ‘;’ ENCLOSED BY ‘”‘ LINES TERMINATED BY ‘\r\n’ (field1, field2);
[Edit: Make sure to check your single quotes (') and double quotes (") if you copy and paste this code]
Done!
A: You can try use Navicat MySQL. I've done this with 250MB+ xlsx file and Navicat handle it flawlessly without breaking a sweat.

d981 | train | From CSV Examples:
Since open() is used to open a CSV file for reading, the file will by default be decoded into unicode using the system default encoding (see locale.getpreferredencoding()). To decode a file using a different encoding, use the encoding argument of open:
import csv
with open('some.csv', newline='', encoding='utf-8') as f:
reader = csv.reader(f)
for row in reader:
print(row)
The same applies to writing in something other than the system default encoding: specify the encoding argument when opening the output file. | unknown | |
d982 | train | i dont think there is any straight forward way of disabling a DropdownMenuItem
but you can have a list of the DropdownMenuItems you want to disable and then when you run setState you can check if that DropdownMenuItem is contained in that list and if it is then do nothing, also check by the DropdownMenuItem text if its contained in that list and if it is then change the color to be greyed out.
Like this
class MyWidget extends StatefulWidget {
@override
_MyWidgetState createState() => _MyWidgetState();
}
class _MyWidgetState extends State<MyWidget> {
var rentPeriods = <String>['one', 'two'];
final disabledItems = ['one'];
var rentPeriod;
@override
Widget build(BuildContext context) {
return DropdownButton<String>(
value: rentPeriod,
items: rentPeriods.map((String value) {
return DropdownMenuItem<String>(
value: value,
child: Text(
translate("expense.$value"),
style: TextStyle(
color: disabledItems.contains(value) ? Colors.grey : null,
),
),
);
}).toList(),
onChanged: (value) async {
if (!disabledItems.contains(value)) {
setState(() {
rentPeriod = value;
});
}
},
);
}
}
A: You can create your own disable customization, changing the color and the callback of onChangedfunction in the DropdownButton, like this example:

Use cSplit from my "splistackshape" package:
cSplit(cases, "helplinks", ",", "long")[, helplinks := gsub(
'character\\(0|c\\(|\\"', "", helplinks)][, list(
caseid = list(caseid)), by = helplinks]

Old answer
I'm assuming you're starting with something like this:
df <- data.frame(
name = c("x", "y", "q", "w"),
alias = I(list(c("R","V","Q"), "Z", c("A", "R", "M"), c("C","A","R")))
)
df
# name alias
# 1 x R, V, Q
# 2 y Z
# 3 q A, R, M
# 4 w C, A, R
If that's the case, here's one approach using listCol_l from my "splitstackshape" package in conjunction with "data.table".
library(splitstackshape)
listCol_l(df, "alias")[, list(name = list(name)), by = alias_ul]
# alias_ul name
# 1: R x,q,w
# 2: V x
# 3: Q x
# 4: Z y
# 5: A q,w
# 6: M q
# 7: C w
You don't really need "splitstackshape" for that, so if you want to remove the self-promotion part of my answer and just use "data.table", you could do:
library(data.table)
as.data.table(df)[, list(
alias = unlist(alias)), by = name][, list(
name = list(name)), by = alias]
A: First we clean up the "character(0"'s. Then we read in those character values that were once lists but now need to be scan-ned. Then we apply a function that makes a dataframe from every line:
good.case <- cases[ grepl("c\\(", cases$helplinks),]
lapply( split(good.case, row.names(good.case) ), function(d){
vec <- scan(text=gsub("c\\(|[, ]", "", d$helplinks) ,what="")
do.call( data.frame, list(caseid=d$caseid, alias=vec) )
}
)
#-------
#Read 4 items
#Read 6 items
$`2`
caseid alias
1 7758128 60107
2 7758128 56085
3 7758128 57587
4 7758128 3000020
$`5`
caseid alias
1 8829620 60107
2 8829620 3000023
3 8829620 3000020
4 8829620 60107
5 8829620 56085
6 8829620 57587
expanded <- lapply( split(good.case, row.names(good.case) ), function(d){
vec <- scan(text=gsub("c\\(|[, ]", "", d$helplinks) ,what="")
do.call( data.frame, list(caseid=rep(d$caseid, length(vec)), alias=vec) )
}
)
#Read 4 items
#Read 6 items
Now we bind the dataframes together:
do.call(rbind, expanded)
#---------------
caseid alias
2.1 7758128 60107
2.2 7758128 56085

d985 | train | It sounds like you used XRow.getString, which (sensibly enough) retrieves the array as a single large string. Instead, use XRow.getArray and then XArray.getArray. Here is a working example:

oResult = oStatement.executeQuery(sSQL)
s = ""
Do While oResult.next()
sql_array = oResult.getArray(2)

d987 | train | Since Spark retains the right to regenerate datasets, at any time, that may be what's happening, in which case caching the results of expensive transformations can lead to dramatic improvements in performance.
In this case, it looks at first glance like itemset is the heavy hitter, so
itemset = getCombinations(itemset_count.select("itemsets")).cache
May pay dividends.
It should also be noted that building up a list by appending in a loop is generally a lot slower (O(n^2)) than building it by prepending. If correctness isn't affected by the order of itemset_counts, then:
itemset_counts = itemset_count :: itemset_counts
will produce at least a marginal speed-up. | unknown | |

c.com,9.17.6.7
If using OS X, use Homebrew to install GNU sed.
A: Use the @csv format to produce CSV output from an array of the values.
cat test.json | jq -r '.[] | [.host, .ip] | @csv'
The -r option is needed to get raw output rather than JSON, which would wrap an extra set of quotes around the result and escape the quotes that surround each field. | unknown | |

d990 | train | assign overwrites the content of the vector where as copy with back_insert_iterator does a push_back on the vector thus preseving its content.
EDIT: If the question is generic (i.e. whether to use a member function defined in the container or an algorithm), I prefer to use the member function as it might have been optimized for the particular container compared to a generic algorithm.
A: Complementing Naveen's answer, using std::copy() is also much more versatile, as this way you can easily write to any output iterator. This could be a stream or something entirely custom.
A: In the general case, prefer member functions to functionally-equivalent algorithms. Scott Meyers discusses this in depth in Effective STL.
A: In essence, they are the same. Vector's reallocation behavior (defined in terms of how it behaves with push_back) avoids too many reallocations by progressively using more memory.
If you need identical code to work with multiple container types (i.e. you're writing a template), including those containers not in the stdlib, then generally prefer free functions.
If you don't mind rewriting this code if/when container types change, then you can prematurely optimize if you like, or simply use whichever is more convenient.
And just for completeness' sake, copy+back_inserter is equivalent to vector::insert at the end(), while vector::clear + copy+back_inserter is equivalent to vector::assign.
A: Your question can be generalized as follows:
When dealing with STL containers,
should I prefer to use member
functions or free-standing functions
from <algorithm> when there are functional equivalents?
Ask 10 programmers, and you'll get 12 responses. But they fall in to 2 main camps:
1) Prefer member functions. They are custom-designed for the container in question and more efficient than the <algorithm> equivalent.
2) Prefer free-standing functions. They are more generic and their use is more easily maintained.
Ultimately, you have to decide for yourself. Any conclusion you come to after giving it some reasoned, researched thought is better than following anyone else's advice blindly.
But if you just want to blindly follow someone's advice, here's mine: prefer the free-standing functions. Yes, they can be slower than the member functions. And "slow" is such a dirty word. But 9 times out 10 you just don't (or shouldn't) care how much more efficient one method is than the other. Most of the time when you need a collection, you're going to periodically add a few elements, do something, and then be done. Sometimes you need ultra-high performance lookup, insertion or removal, but not normally. So if you're going to come down one one side or the other with a "Prefer Method X" approach, it should be geared for the general case. And the approach that prefers the member methods seems to be slanted towards optimization -- and I call that a premature micro-optimization. | unknown | |
d991 | train | Did you get over this issue?
I've tried with bootstrap 4.0 but I didn't see any issue, so my suggestions are:
*
*check your java version, make sure it is 1.8.171+
*make sure the corda.jar (in your build /nodes/notary/corda.jar) is correct because bad network may cause the incomplete corda.jar downloaded
*make sure you've got the tools from official website instead of copying from other way where the bootstrap jar file might be broken
*last, as always, please try to use the latest version bootstrap: 4.3, to utilise the best Corda:
https://software.r3.com/artifactory/corda-releases/net/corda/corda-tools-network-bootstrapper/4.3/
A: I had a similar problem (not with that particular JAR file, but I'm using that file's name in my examples). Here's how I worked out what was wrong.
These troubleshooting steps may help others who find this issue (but not the OP as the dates show it can't be this issue).
I started by trying to validate the JAR file by inspecting its contents:
$ jar -tf corda.jar
This showed me that it was indeed invalid. In my case, I saw:
java.util.zip.ZipException: error in opening zip file

at sun.tools.jar.Main.run(Main.java:293)
at sun.tools.jar.Main.main(Main.java:1288)
I then looked at the size of the file:
$ ls -alh corda.jar
In my case, it was 133 bytes, which seems a bit small for a JAR file, so I cated it and saw this:
$ cat corda.jar

d992 | train | The root of your problem appears to be that your server does not support SSL or does not have it enabled. The message:
The server does not support SSL
may only be emitted by org/postgresql/core/v3/ConnectionFactoryImpl.java in enableSSL(...) when the server refuses or doesn't understand SSL requests.
Sure enough, in your update you say that you had the SSL-related options in postgresql.conf commented out. Them being commented out is the same as them being not there at all to the server; it will ignore them. This will cause the server to say it doesn't support SSL and refuse SSL connections because it doesn't know what server certificate to send. PgJDBC will report the error above when this happens.
When you un-commented the SSL options in postgresql.conf and re-started the server it started working.
You were probably confused by the fact that:
&ssl
&ssl=true
&ssl=false
all do the same thing: they enable SSL. Yes, that's kind of crazy. It's like that for historical reasons that we're stuck with, but it's clearly documented in the JDBC driver parameter reference:
ssl
Connect using SSL. The driver must have been compiled with SSL
support. This property does not need a value associated with it. The
mere presence of it specifies a SSL connection. However, for
compatibility with future versions, the value "true" is preferred. For
more information see Chapter 4, Using SSL.
As you can see, you should still write ssl=true since this may change in future.
Reading the server configuration and client configuration sections of the manual will help you with setting up the certificates and installing the certificate in your local certificate list so you don't have to disable certificate trust checking.
For anyone else with this problem: There will be more details in your PostgreSQL error logs, but my guess is your PostgreSQL config isn't right or you're using a hand-compiled PostgreSQL and you didn't compile it with SSL support.
A: If you are using a self-signed certificate you need to add it to your trusted key store of your Java installation on the client side.
You find the detailed instructions to achieve this here: telling java to accept self-signed ssl certificate
A: In your connection string, try
?sslmode=require
instead of
?ssl=true
A: Use param sslmode=disable. Work for me. Postgresql 9.5 with jdbc driver SlickPostgresDriver. | unknown | |

d996 | train | Generally I would recommend that you make the changes immediately. If there's to be a "grace period", then implement that on the server side (you can do it client side too if it will improve user experience).
So if someone upvotes a post, it is saved immediately via ajas, but then if they change their minds within the grace period, the server undoes the vote. Once the "grace period" is up, the server rejects the change.
A Facebook post would (obviously) be saved when you click "Post", etc. -- but it wouldn't be saved before then.
Something like Blogger or Google Docs is another issue altogether -- where it's automatic saving every x number of seconds. That is purely up to the developer. Generally you want to make it as often as possible without impacting performance or decreasing the user experience. | unknown | |
d997 | train | Your algorithm logic structure smells a lot, this is what I see:
*
*read all non empty lines into lines_in_file (looks good to me)
*for EVERY line (problematic, requires additional logic in inner loop):
*
*if not "P3", try to parse [EVERY] line as integer and set effect_choice (it's not clear from your code, what happens on lines where several integers are provided, but judging from your problem description the first integer is successfully parsed by strToInt function)
*if "P3", the current line and next two are copied to output
*[EVERY] line is parsed as vector of triplets of numbers
*effect is set by new effect for actual value of effect_choice (for EVERY line, also you don't delete the effect at end, so you are leaking memory in per-line counts. Also your current effects look like they may be implemented as static functions of "process" function type, so you don't need to allocate each of them, just store the particular memory address of requested function. And you call it processImage, while you are processing only line, not whole image.
*effect is run for current line triplets
*the line triplets are outputted
*loop to next line (!)
So for example for input:
2
3
P3
1 2
255
50 50 50
1 2 3
I believe (can't run it, as you didn't provide lot of code) this happens:
lines are read, and per particular line this happens:
line "2": effect_choice = 2, effect = RemoveGreen, zero triplets parsed into points, RemoveGreen::processImage() run over empty vector, empty vector printed (ie nothing).
line "3": effect_choice = 3, effect = RemoveBlue, zero triplets parsed into points, RemoveBlue::processImage() run over empty vector, empty vector printed.
line "P3": Lines: {"P3", "1 2", "255"} are printed, zero triplets parsed into points, RemoveGreen::processImage() run over empty vector, empty vector printed.
line "1 2": effect_choice = 1, effect = RemoveRed, zero triplets parsed into points, RemoveRed::processImage() run over empty vector, empty vector printed.
line "255": effect_choice = 255, zero triplets parsed into points, RemoveRed::processImage() run over empty vector, empty vector printed.
line "50 50 50": effect_choice = 50, one triplet {50, 50, 50} parsed into points, RemoveRed::processImage() run over it, modified triplet outputs {0, 50, 50}.
line "1 2 3": effect_choice = 1, effect = RemoveRed, one triplet {1, 2, 3} parsed into points, RemoveRed::processImage() run over it, modified triplet outputs {0, 2, 3}.
All of this should be clearly visible in debugger, while stepping over the code, so you probably are not debugging it, which gets downvoting the question from me, and you will pay in tremendous pain over time, as debugging without debugger is lot more difficult.
Also writing code without thinking about algorithm and code architecture makes the need of debugging lot more likely, so you wasted even more time here, by starting by writing the code.
You should have first design some algorithm and code architecture (what data are processed, how, when new memory is needed, how it will be freed, where the code need to loop, where it need to skip over, or run only once, etc).
Write only overview of how it will work into single-line comments, then split too generic comments into simpler steps until they can be implemented by few lines of C++ code, and move/modify them around until you feel the wanted algorithm will be implemented with minimal "cruft" added (most of the comments does, what is really requested, like "set red in point to zero", and any processing/preparations/moving/etc is minimized only to cases where you can't avoid it by smarter design). (for example in your current code you can read through the header of the file without looping, and start looping only after the pixel data pours in)
Then write the code, start probably with some empty function definition so you can already "run" it in debugger and verify the emptiness works, then implement the comment (or small group of them) which you feel is clear enough to be implemented and can be tested easily (no big dependency on yet-to-implement parts). Debug + test new code. If it works, try to clean up the source to remove anything not really needed, work-in-progress variable names, etc... Then verify it works in final version.
And do it again for another comment (group of), until the implementation is done.
Using unit-testing makes the write-short-code, test+debug, clean-up-source rounds even easier, especially in cases like this, where I/O are pure data, so it's easy to feed specialized test input data into test, and verify the expected output data were produced. | unknown | |

d999 | train | I took a look at the repository. You are correct that svndumpfilter cannot be used to rename a file throughout the history, so I wrote a small script that does the renaming in the dump file. The only tricky part was to add the creation of the tags and branches folder. To use the script, you should make a cronjob or similar that:
*
*downloads the latest Putty SVN dump file:
$ wget http://www.chiark.greenend.org.uk/~sgtatham/putty/putty-svn.dump.gz
*fixes the dump file with the script:
$ zcat putty-svn.dump.gz | fix-dump.py > fixed.dump
*loads it into a new empty repository:
$ svnadmin create putty
$ svnadmin load putty < fixed.dump
*converts the Subversion repository into a Mercurial repository:
$ hg convert file://$PWD/putty
As far as I can see, the branches and tags are created correctly.
You ask for continuous pulling (incremental conversion). Luckily, both hg convert and hgsubversion support this. You'll need to redo steps 1–3 every day before you can convert the changesets into Mercurial. This will work since the first three steps are deterministic. That means that your putty SVN repository behaves as if the Putty developers worked directly in it using the proper branch and tag names you maintain there.
The script is below:
#!/usr/bin/python
import sys, re
moves = [(r"^Node(-copyfrom|)?-path: %s" % pattern, r"Node\1-path: %s" % repl)
for (pattern, repl) in [(r"putty-branch-(0\...)", r"branches/\2"),
(r"putty-(0\...)", r"tags/\2"),
(r"putty(/|\n)", r"trunk\2")]]
empty_dir_template = """\

created_dirs = False
for line in sys.stdin:
if not created_dirs and line == "Node-path: putty\n":
sys.stdout.write(empty_dir_template % "tags")
sys.stdout.write(empty_dir_template % "branches")

Disclaimer: Applying this patch makes the current vsftp release compile, I have now clue wether the created binaries work correctly or not.
A: I'm using SLES 11 sp1 64bit, kernel 2.6.32, gcc ver 4.3.4; changing or removing FORTIFY_SOURCE made no difference, get same error. I'm not a c programmer - the flags O_DIRECTORY and O_CLOEXEC are in seccompsandbox.c:
static const int kOpenFlags =
O_CREAT|O_EXCL|O_APPEND|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC|O_LARGEFILE;
It compiles if you remove them but that really fills me with confidence....
The vrf_findlibs.sh is also broken, I had to rejig the script so it found a 64bit version of libcap first or it keeps selecting the 32bit copy (the -lcap doesn't work either, says it isn't found):
# Look for libcap (capabilities)
if locate_library /lib64/libcap.so; then
echo "/lib64/libcap.so.2";
elif locate_library /lib/libcap.so.1; then
echo "/lib/libcap.so.1";
elif locate_library /lib/libcap.so.2; then
echo "/lib/libcap.so.2";
else
locate_library /usr/lib/libcap.so && echo "-lcap";
locate_library /lib/libcap.so && echo "-lcap";
locate_library /lib64/libcap.so && echo "-lcap";
