Reverse Order on QStringList slow...?

[patrik08]

I a

• Trying to create rsync like functionality on top of webdav
• Trying to use the entity tags as a way to see if a file has changed?

Simplest way:
Ignore the entity tag, and only use the last modified date (compare the one from the webdav with the one locally, taking into account the different times of the computers).

Harder way:
Store the entity tag of a file together with the lastmodified time of the file(when you knew that the file was identical to the one on the server) and a md5/sha1 sum of the file....;-)

Bandswitsch !! get the file to check md5 ?? or save md5 key on server && local??
The last mod time is never same as local file.... time from incomming Put http Method... (upload time stay as lastmod time)


I test .... i upload a file called: qt4.2compile.txt (ubuntu fetschi package build)
upload to webdav .....
http://ppk.ciz.ch/qt_c++/qt4.2compile.txt
http://ppk.ciz.ch/qt_c++/ dir list time ...

first upload original file Last mod time 20 Feb 2007 18:41:11
qt4.2compile.txt

Propfind http method say .... on first upload ... (last mod is now incomming time & created time...)

if i download the file <lp1:getetag>"bc4d3-ef-daa35300"</lp1:getetag> stay same...

Also only this <lp1:getetag> have a working info to check if a remote is newer or the local file....

Subversion software versioning working on the same way .... why? svn is on top on a webdav server and dir.... propfind http method.... i check code from esvn wo is qt based....

[wysota]

The difference is local remove is a function running on self.... and no signal!!!

function remove( path ) { /* start on top and work to down */
make ....
next level remove(here);
}

on Remote each action must start a signal go delete and emitter go back to next file or dir ..... /* from down dir comming up at end remove the top folder... */

So what that there is no signal? As long as you're deleting files, you can queue deletes. And even if you want to have a synchronous flow, you can always emulate it using an event loop, that's what QTestLib does.

???

get the file to check md5 ??

You do have the file locally. If you just synched the file, you know both are equal, thus you can calculate the md5 of the local file and associate it to the remote etag

or save md5 key on server && local??

You have the etag to know the state of the server, don't you?

The last mod time is never same as local file....
time from incomming Put http Method... (upload time stay as lastmod time)

Well, there are always ways to set the modified time I would think ;-)

I test .... i upload a file called: qt4.2compile.txt

ok

(ubuntu fetschi package build)

Now you know both files are equal, you calculate the md5 of the file you just uploaded, and correlate it with the etag you get from the server...

if i download the file <lp1:getetag>"bc4d3-ef-daa35300"</lp1:getetag> stay same...

Well, maybe the server is actually checking if the file did change. Even if the modified since was changed (you did try to modify it), the version of the file is still the same. so no error there, see also the RFC:

A "strong entity tag" may be shared by two entities of a resource only if they are equivalent by octet equality.

Since your file is equal byte-by-byte, the strong-entity-tag, which your etag is, can remain the same.

Also only this <lp1:getetag> have a working info to check if a remote is newer or the local file....

Subversion software versioning working on the same way .... why? svn is on top on a webdav server and dir.... propfind http method.... i check code from esvn wo is qt based....

What does svn have to do with it? What feature of svn do you want to emulate?
By the way, you can work with svn without webdav. (Even if most people do not ;-)



What exactly is the problem you are seeing. Take your time please and try to write it in a way that helps me to understand you clearly.

(Yes, it is hard to write things down in a precise way, especially when english is not your native language. Mine is german by the way :-)

Mine native is Italian - Swiss-German - Portuguese .... now the problem to RSync folder is of topic here.... i hope to find an answer on apache2 mod_dav or on subversion... documentation... tanks...

Nice selection ;-)

Good luck with that :-)
