By default log rotate shifts file name's index on each rotation. I would like to keep names for old files. On each rotation: create new files + delete outdated.
Reason: every time I am rsycn those files with another sever, I have to download ALL file instead of simply downloading newly created ONE file and removing outdated ONE file.
Thanks

I cannot find an answer to for several weeks. Perhaps my experience in development is not so great :) One site uses the JCH Optimize plugin and I noticed that after clearing the old memory (caches), the CSS and JS file links do not change, i.e. the names of these files remain old. The problem is that the browser checks the file name and if it has not changed, then the site visitors show the old version of the style file. The question itself, where in the plugin (in which code file) i can add some GET parameters ?vers = 1.1 so that for the browser it is a new file and it would update the information for users. I will be glad to hear any solutions. Thanks.
The names of the combined css and javascript files are keyed from the names of the individual files on the page. Clearing the cache will not cause the plugin to generate a different file name.
As of version 7.0.0, there is an option to generate a different cache key if you want to change the names of the combined file. Update your current version to get that capability.
I am using CPANEL and there I edited and created my website directly.
I had php file with about 300 lines and somehow I changed encoding to something other than utf-8. When I changed it and saved it saved only first 10-20 lines of my file. I cannot redo (ctrl+z) to bring my code back.
So my question is how to get lost file back? I haven't closed it yet so session is still valid. Please fast help. I know I will get downvote but I am in despair....
You may be lucky depending on backups...
If you go into the Files section and click Backups, then select the most recent backup where you know your file still existed in the correct state (before you made the encoding change).
If you then save the file and unzip it, hopefully your file will be there and you will be able to re-upload it. Good luck!
In future, definitely develop offline and use source control then upload copies of your file to avoid this.
Sorry if this seems stupid but I wonder if it's possible to add a database entry after an ftp upload.
To be more clear, thanks to winSCP I have several folders sending everything I put in there automatically to my server.
However, I would like to create a mysql entry for each uploaded files and once again, automatically. Is it possible to do that? How?
To gives the full details of what I need to do, you can read the following.
I have several folders with pictures and each folders are uploaded automatically.
Each of those folders belong to one user and the goal is to give them an account and allow them to see and download those files through a web interface. Since one account = one folder, that's kinda easy.
And I think a simple .htaccess can simply secure things so one user can only see and download the file in his own repository, no?
However if I want them to be able to see what's new (=something they didn't download or simply mark as read) I think I need a table to manage those files.
Something like id | file (string) | read (bool).
If you think this way to proceed is bad, they I'm open to change how to do things, but to be clear uploading the file need to work this way. Not using any kind of formulary.
Thanks for reading that, sorry for my english.
Your problem contains three steps:
Folders/Files been automatically uploaded to your server directory, as you say, this been efficiently handled by winSCP.
You need to update your database with all the files and folders present in your server directory.
You need to update whether or not it is been read/downloaded by the user.
Since your first step is in place, we don't need anything there. For second step, you should write a script and schedule that script to run at a fixed time interval using CRON (if using LINUX or UNIX, or WINDOWS). The script would be responsible to create a list of file(s) present in the directory, and simply insert the file(s) information that are not present in your database.
EDIT:
This edit is to describe how your script file should work. As I explained, the cron jobs would simply help you run your script file in fixed set of interval (which can be every minute, or every hour, or every day, and so on). Lets say your database table has following columns:
fileid (varchar[20])
filepath (varchar[20])
status (boolean)
Your script file should do following things:
Create a list of existing filepaths in your server directory
Run a select query, create a list of existing filepaths from database table.
Compare list1 with list2, and find the ones that doesn't exist in list2 (This would give you a list of filepath that needs to be inserted into table)
Just insert the list of file paths you got above, and set there status to be false (which means the file is not read/downloaded yet)
NOTE: Please keep in mind that I am not advising right now that how your database table should look like. It can be what you have proposed or can even differ depending on your will or requirements.
For the third step, simply keep the status of your file to be unread when creating entries in your table from the second step, and then when user click on the file link in your application whether to view or download it, send a POST request to your server updating the file status to be marked as read.
Let me know if this helps!
I'd like to list all files from a remote folder (let's say www.mysite.com/folder, and this folder is already configured through .htaccess for directory listing).
After listing, i'll need to copy the remote files to a local folder.
For listing/copying only local files, I was using NSFileManager, but this doesn't work for the remote ones. I've been looking for some reference on it, but couldn't find so far...
While NSFileManager can in fact handle URLs, it's not going to download the apache HTML page with the directory listing and parse it to do this... you'll have to do that yourself. This sounds like a strange thing to be doing however, so you may want to explain the reasoning and we may be able to suggest better alternatives. WebDAV comes to mind.
UPDATE: Based on your comment, why not put the resources in a .zip (or similar) file and download that? Then it's a single download and you can just extract it locally. Sounds like it would save a lot of headaches and would make it much easier to do things like checksum validations on the download(s).
Maybe it's not the best way, but - instead of get directory listing - we're going to keep a list of files that should be transfered (could be a .txt or .xml).
For downloading and tracking multiple requests, we're going to use ASINetworkQueues (more details can be found on http://allseeing-i.com/ASIHTTPRequest).
Another good suggestion, given by d11wqt (thank you for your help), is compressing the files and just make one single request.
On my site a user may upload a file (pic, zip, audio, video, whatever). He then may decide to replace it with a newer revision. This user may upload a file, make a post then decide to put up a new revision replacing the old (lets say its a large zip or tar.gz file). Theres a good chance people may be downloading it if he sent out an email or even im for the home user.
Problem. I need to replace the file and people may be downloading and it may be some minutes before it is deleted. I dont want my code to stall until i cant delete or check every second to see if its unused (especially bad if another user can start and he takes long creating a cycle).
How do i delete the file while users are downloading the file? i dont care if they stop i just care that the file can be replaced and new downloads are the new revision.
What about referencing the files indirectly?
A mapping script, maps a virtual file entry from your site to a real file . If the user wants to upload a new revision of his file you just update the mapping, not the real file.
You can install a daily task that scans all files and deletes all files without a mapping and without open connections.
lajuette's answer is right, the easiest solution is to work around the file locking altogether:
When a user uploads file foo.zip, internally store it as foo-v1.zip.
Create a mapping file somewhere (database, code, whatever) that maps foo.zip to foo-v1.zip.
Rather than exposing a direct link to the file, expose a link to a service that gets the file: mysite.com/Download?foo.zip or something. This service uses the mapping to determine which version of the file to send to the client.
When a new version is uploaded, create foo-v2.zip and update the mapping file.
It wouldn't be that hard to write a scheduled task that cleans up old, un-mapped files.
If your oppose to a database and If the filenames are in a fix format (such as user/id.ext) you could append the id with a revision number and enumerate the folder using a pattern (user/id-*) and use the latest revision.
