Re: [Cppcms-users] E-Mails Missing

[Marius C. <mf...@gm...>]

CppCMS 1.1 Progress report (scoop 1st beta is coming...) and the rest
of them were all in the spam folder as many of your emails from your
yahoo account sent to my gmail. I had to create a special filter to
send them to my inbox ( see how much I value your emails, lol ). It
kept complaining that your emails seem to not come from yahoo servers
themselves or something like that.

  Since I created the filters it just says that it didn't send them to
spam because I asked it not to.

Re: [Cppcms-users] E-Mails Missing

[redred77 <red...@gm...>]

I received  "CppCMS 1.1 Progress report". Well it was found from spam
folder.

Other mails you mentioned are not found even in spam folder. Gmail's spam
folder is deleted automatically in certain period but I don't think that
caused the problem since your mails are not old enough.

I see your message from other people's reply mail but not from your
original message time to time.

As you can see, I'm using gmail.

Thanks.

Re: [Cppcms-users] About exposed cookie management

[redred77 <red...@gm...>]

Yeah, I used browser based expiration. It lost session before browser is
closed.

I opened a new ticket for it.
http://sourceforge.net/p/cppcms/bugs/143/


Great to hear new beta release anyway! (I aknowledged this morning. Recent
mail was in spam folder)
Very interesting improvements. Awesome works!


Happy Christmas!

Re: [Cppcms-users] About exposed cookie management

[Artyom B. <art...@ya...>]

What kind of session expiration you use? fixed, renew or browser?
See session cookie and related cookies should have same expiration time.  So when session expiresthe cookie should disappear as well.
I'm thinking that maybe you use browser session and it expires before the browser is closed. And than cookie is not properly deleted because session does not know what keys are exposed there and what shouldbe deleted.
It looks to me like a bug... Also from what  I think it happens only with browser based session (i.e. cookies without max-time/expires properties) that expires before the browser is closed.
Can you confirm and if this is right open a ticket?
As a workaround of the issue you can use
// test if there is no session key but cookie exists.if(!session().is_set("test")    && request().cookies().find("[prefix]_test")!=request().cookies().end()) {    // remove the cookie    response().set_cookie(cppcms::http::cookie("test","",0));
}

Hi
I'm testing cppcms, and stuck with cookie management.This is sample code I'm using.

session().set("test", "testvalue");session().expose("test");
I could see the cookie exposed like "(prefix)_test".
Also, I could see main encrypted session cookie which contains all info.

It works as intended but when main session expires, things not work as I expected."test" key is gone away since main session cookie was invalid anymore, but exposed "test" cookie key was still alive and transferred between client and server.


1. Is it right behaviour? Or have I misconfigured something?I thought that session() in cppcms guarantees the lifecycle of "main session key" and "exposed cookie" together.
When session key is invalid anymore, I thought cookie would be deleted too.
I quite don't know the mechanism underlying cppcms, so I want to know if I'm doing right.




2. Actually, it's not a big problem because I can check "test" key from session and invalidate from server.
Currently, I'm deleting exposed cookie key like this.


 if (!session().is_set("test")) { session().set("test", ""); session().expose("test"); }

When there's no valid "test" key in session, it makes that key with empty string and expose it.
I tried many other methods, like hide(), clear(), but only this worked when previous session already expired.
I feel like I'm doing in inefficient way.

[Cppcms-users] About exposed cookie management

Hi

I'm testing cppcms, and stuck with cookie management.
This is sample code I'm using.

session().set("test", "testvalue");
session().expose("test");

I could see the cookie exposed like "(prefix)_test".
Also, I could see main encrypted session cookie which contains all info.


It works as intended but when main session expires, things not work as I
expected.
"test" key is gone away since main session cookie was invalid anymore, but
exposed "test" cookie key was still alive and transferred between client
and server.

I thought that session() in cppcms guarantees the lifecycle of "main
session key" and "exposed cookie" together.

[Cppcms-users] spdlog

[Василий Т. <par...@gm...>]

Hello, guys.
1) Is there any way to use another log destination for some special data?
Ideally, i would like to log app-wide messages to /var/log/my_app.log (with
several rotated parts) and some of important network data to another
location (1 file per day). It looks like booster::log has a lack of
functionality :( Dont you want to switch to spdlog?
2) I need to reload configuration, at least application-specific parts. Wat
is the best way to achieve it in multithreaded environment? Do I need to
make some kind of synchronized wrapper for this part of settings? It would
be very useful to implement SIGHUP to refresh logging, custom and, may be,
other settings.
Thanks.

[Cppcms-users] CppCMS 1.1 Progress report (scoop 1st beta is coming...)

[Artyom B. <art...@ya...>]

Hello,
I'm getting ready to release next CppCMS beta version  1.1 (that would become stable as 1.2)
Some preview of the work that was done so far:
  http://cppcms.com/wikipp/en/page/cppcms_1_2_whats_new

There are still few relatively small tasks in the TODO list before beta will be officially ready. 
  http://cppcms.com/wikipp/en/page/cppcms_1x_tasks#CppCMS.1.1.0.-.Next.Release

More than that  I'm changing the release policy to something that I should do for a looooong time ago:
  release early, release often

CppCMS 1.1 was for too long in development and it isn't good :-)
I want you guys to looking on it - try to build the version from trunk, try new API and report your impressions.
If some API issues are discovered I can make API changes before 1.2 is out. However once 1.2 is released... the API will be frozen.
Thank you!

Re: [Cppcms-users] About escape filter

[Artyom B. <art...@ya...>]

Actually you bringing relevant points.
Also AFAIK rss is XML and default escaping should work.Escaping '\'' in general isn't required for HTML unless you use variables in attributes quoted with
single quote. So probably I'll extend default filter to filter quote mark as well. Also I don'tthink it is actually real issue but may be somewhat misleading.
Nevertheless remember you can always define your own filters for your specific cases:http://cppcms.com/wikipp/en/page/cppcms_1x_templates_comm#Description
 Also note I'm planning to add more filters like filter for json/javascript
and I'm planning to add "default filter scope or something like that"

1. I know that there is escape filter in cppcms already, but I found that sometimes it's not enough.
According to rss validator, and rss spec, < > " & characters must be escaped to hex.
validator : https://validator.w3.org/feed/rss spec : http://www.rssboard.org/rss-profile#data-types-characterdata

A publisher SHOULD encode "&" and "<" in plain text using hexadecimal character references. When encoding the ">" character, a publisher SHOULD use the hexadecimal reference &#x3E;.

Using hex code is for compatibility reason, but many rss reader programs don't recognize &quot; still. For example, SNS management site hootsuite.com's internal rss reader takes some feed as invalid when &quot; character is in title tag. Actually they don't need to update the rss reader because the spec says it should be hex encoded.
So, I would like to suggest adding encode_hex like method. It is essential when publishing rss feed from website.


2. Escaping (') apostrophe (single quote) character.
PHP's htmlspecialchars() function escapes apostrophe (single quote) when such flag is set.
http://php.net/manual/en/function.htmlspecialchars.php

Also here are 5 item that are XML, HTML predefined entities.https://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references#Predefined_entities_in_XML

I can think of some situations that user input may harm the website when single quote is not escaped since web developers may use single quote at double quote places. Especially, with javascript I prefer to use single quote over double quote.

For security, I would like to suggest apostrophe must be escaped.


3. I copied from existing cppcms source code and made similar escape method which escapes xml entities to hex and single quote (apostrophe)

std::string util::escape_hex(std::string const &s){ std::string content; unsigned i, len = s.size(); content.reserve(len * 3 / 2); for (i = 0; i<len; i++) { char c = s[i]; switch (c){ case '<': content += "&#x3C;"; break; case '>': content += "&#x3E;"; break; case '&': content += "&#x26;"; break; case '\"': content += "&#x22;"; break; case '\'': content += "&#x27;"; break; default: content += c; } } return content;}

It works as intended. Original source code is stable, and I just modified some.

Depending on the output, different filters are needed. You might find

[Cppcms-users] About escape filter

[redred77 <red...@gm...>]

1. I know that there is escape filter in cppcms already, but I found that
sometimes it's not enough.

According to rss validator, and rss spec, < > " & characters must be
escaped to hex.

validator : https://validator.w3.org/feed/
rss spec : http://www.rssboard.org/rss-profile#data-types-characterdata

A publisher SHOULD encode "&" and "<" in plain text using hexadecimal
character references. When encoding the ">" character, a publisher SHOULD use
the hexadecimal reference &#x3E;.

Using hex code is for compatibility reason, but many rss reader programs
don't recognize &quot; still. For example, SNS management site hootsuite.com's
internal rss reader takes some feed as invalid when &quot; character is in
title tag. Actually they don't need to update the rss reader because the
spec says it should be hex encoded.

So, I would like to suggest adding encode_hex like method. It is essential
when publishing rss feed from website.



2. Escaping (') apostrophe (single quote) character.

PHP's htmlspecialchars() function escapes apostrophe (single quote) when
such flag is set.
http://php.net/manual/en/function.htmlspecialchars.php

Also here are 5 item that are XML, HTML predefined entities.
https://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references#Predefined_entities_in_XML

I can think of some situations that user input may harm the website when
single quote is not escaped since web developers may use single quote at
double quote places. Especially, with javascript I prefer to use single
quote over double quote.

For security, I would like to suggest apostrophe must be escaped.



3. I copied from existing cppcms source code and made similar escape method
which escapes xml entities to hex and single quote (apostrophe)


std::string util::escape_hex(std::string const &s)
{
std::string content;
unsigned i, len = s.size();
content.reserve(len * 3 / 2);
for (i = 0; i<len; i++) {
char c = s[i];
switch (c){
case '<': content += "&#x3C;"; break;
case '>': content += "&#x3E;"; break;
case '&': content += "&#x26;"; break;
case '\"': content += "&#x22;"; break;
case '\'': content += "&#x27;"; break;
default: content += c;
}
}
return content;
}


It works as intended. Original source code is stable, and I just modified
some.



4. I want to discuss adding new escape method, and about apostrophe. And I
want to know if there's some issues that I didn't know.

for (it=postData.begin(); it!=postData.end(); ++it){
//save and map data to form
response().out() << (*it).first << " => " << (*it).second;

return;


}


are there any methods to get dynamic form base on html form manipulation?

Re: [Cppcms-users] dynamic form

[mawan s. <ma...@gm...>]

My problem is :

Can cppcms form receive a value from POST process that is not defined in
the form object? and then post variables are mapped to the form data?

[mawan s. <ma...@gm...>]

Dear All

I found code in blog example .. . It is about form definition in post.h
Why declare add_to_cat_list form? Is it as a group only ?

std::vector<cppcms::widgets::checkbox *> add_to_cat_list;
std::vector<cppcms::widgets::checkbox *> del_from_cat_list;

cppcms::form inputs;
cppcms::form buttons;
cppcms::form add_to_cat;
cppcms::form del_from_cat;

Thankyou

No currently there is no such functionality, however you can create your own sink

The simplest is shutdown the cppcms service upon sighup and start it again:

Hi,

I wasn't able to find the exact problem. The (brute force) solution was, 
just reinstalling the complete vmachine. Now it works fine. :-)

Thank you for your help.

Mostly it is important the intermediate output values.Also look if ICU is linked i.e. ldd /usr/lib/libbooster.so - if it islinked to ICU or not. Artyom Beilis -------------- CppCMS - C++ Web Framework:   http://cppcms.com/ CppDB - C++ SQL Connectivity: http://cppcms.com/sql/cppdb/

 Hi Artyom,
 
 Thank you for the promt answer. For building CppCMS I used the description on http://cppcms.com/wikipp/en/page/cppcms_1x_build. I did not make any special configurations regarding the ICU.

 Hello,
 
 I'm trying to convert a date_time object into a simple timestamp e.g.:
 
 // init environment...
std::locale::global(booster::locale::generator().generate(""));
 cppcms::service srv(argc, argv);

 // get date_time for 1970-01-01 00:00:00
 booster::locale::date_time dtStart(0);
 
 // get timestamp
 int iDifference = dtStart.difference(dtCurrent,

 That code works fine on Machine A.. But when I'm running the program on

ICU Initialization returned: U_ZERO_ERROR



The "not working" machine is Ubuntu 13.10 with the following ICU infos:

I did no further calculations on the date_time objects. The following 
source code is the whole date_time example I was trying out. The 
complete test project is a little bit larger.. But I could try to create 
a small test program and check the behaviour.

// get some time some month ago..
booster::locale::date_time dtCurrentTime;
booster::locale::date_time dtSomeMonthAgo = dtCurrentTime - 
(booster::locale::period::month());

// get date_time for 1970-01-01 00:00:00
booster::locale::date_time dtStart(0);

// get timestamp
int iDifference = dtStart.difference(dtCurrent, 
booster::locale::period::second());

BOOSTER_DEBUG("test") << "Timestamp of dtSomeMonthAgo: " << iDifference;

Thank you very much for your help,

Alex

Re: [Cppcms-users] booster::locale::date_time to timestamp conversion issues / basis for booster::locale::date_time

[Artyom B. <art...@ya...>]

Is CppCMS compiled with ICU on both machines?Is it same CppCMS version? Also can you print all intermediate calculations as well? (i.e. dtCurrentTime,dtSomeMonthAgo and dtStart)In general second difference should be trivial i.e. mostly calculate difference between internal timestamp.

Hello,

I'm trying to convert a date_time object into a simple timestamp e.g.:

// init environment...
std::locale::global(booster::locale::generator().generate(""));
cppcms::service srv(argc, argv);

// ....

// get some time some month ago..
booster::locale::date_time dtCurrentTime;
booster::locale::date_time dtSomeMonthAgo = dtCurrentTime - 
(booster::locale::period::month());

// get date_time for 1970-01-01 00:00:00
booster::locale::date_time dtStart(0);

// get timestamp
int iDifference = dtStart.difference(dtCurrent, 
booster::locale::period::second());

That code works fine on Machine A.. But when I'm running the program on 
Machine B I get weird results..
On Machine A the timestamp for Mon, 26 Oct 2015 12:37:12 GMT is 
1445863032. (correct)
On Machine B the timestamp for Mon, 26 Oct 2015 12:37:12 GMT is 
536870912. (wrong)

The times on the machines are equal too.. timedatectl:

Machine A:
Local time: Do 2015-11-26 14:25:12 CET

Re: [Cppcms-users] Using cache in application constructor

Good question..


In CppCMS 1.0.x I suggest to access cache on first request, i.e. to put in 
main - if something is not cached  load it otherwise use it.

In CpppCMS 1.1.0 - in trunk you can create a cache_interface object
independently from service - for cases when you need cache outside
request/response context.

You obviously can't cache response output this way but it does
not really matter :-)

Currently development on CppCMS 1.1.x i.e. beta of 1.2.0 is under
very active development and I hope to keep it this way until 1.2
is released.

Also note currently trunk is little unstable due to some refactoring
of the internal code - due to implementation of non-blocking interface
for asynchronous applications. Also all the (important) tests now running
fine still there may be some issues.

http://cppcms.com/files/nightly-build-report.html

It is always more efficient to cache final result (for example rendered HTML page)
rather then database for two reasons:

(a) output is cached in already gzipped mode
(b) You already have done all processing.

Of course it isn't possible in many cases.

Caching DB is very good for "long living" data that is complex to retrieve
and not updated frequently.
