FTP 0.5 for GNUstep and Mac

I'm happy to announce a new release of FTP, the file transfer application of the GNUstep Application Project.

It is designed for GNUstep and completely native on the Mac too, with version 0.5 being available as a binary for both for PPC and Intel, as well, of course, as the usual source tarball for Unix.
(Please wait for the GNU.org mirrors to propagate the files or grab the sources from SVN)

There are some new features as well as bug fixes:

• Creation of local and remote directories
• Command to refresh the current directory listing, local and remote
• File renaming, local and remote
• Drag&Drop for uploading a file from GWorkspace/Finder to remote file panel
• better handling of local and remote write errors
• better parsing of File Sizes returned by FTP servers
• better handling of file adding to the views, so that less "refresh" is needed
• Bug fixes with multiple selection uploads
• Code cleanup for better portability (gcc/clang, old and new runtime, Cocoa)

FTP: new features, some polish

I added some long-due functions to FTP, handled by a request dialog

• Local and Remote Rename
• Local and Remote New Folder

Furthermore, currently it is boring that after each operation the file lists are not updated.

I thus changed the core representation, fileTable, to be a mutable array and added basic manipultation methods. I will the progressively add provision to update dynamically the list after operations. Right now I worked on delete. The first impact is that the contents of the selection need always be copied before launching an operation, otherwise operations with selections larger than one element may fail or behave wrongly after the first element got processed.

Also, I noticed that FTP lacks a refresh function. Sometimes after years you notice the most basic things! I'll need to implement that.

FTP 0.4

FTP 0.4, the ftp client of the GNUstep Application project, has been released.

This is release has a couple of new features which should make usage a bit cleaner as well as many bug fixes and portability issues. I would recommend the upgrade. Among the many small changes:

• Reopening connections without restarting FTP is fixed, there were corner cases where this didn't work
• Better progress report, also for file listings. Indeterminate progress if size is unknown.
• 64bit and portability fixes. Smaller fixes about corner cases with empty selections and empty files and interface locking.
• When disconnecting, the remote connection gets cleared.
• More minor but annoying bugs, like problems with large selections on Cocoa. 

FTP running on NetBSD, Sleek theme applied

FTP 0.3 Released

FTP 0.3 got finally a release! Many small fixes in the build system, better portability and updates.

You can see it in the screenshot running on Windows 7 with the native windows theme!

FTP 0.2 released

Finally, after months of delays and tweaks, FTP 0.2 is out! FTP is the FTP application in GAP for GNUstep and Macintosh.

Externally, few changes can be noticed: a new icon, the correct fixed pitch font in the log window and little more.

Internally, several changes happened though. Two are the main news.

First, the socket core was rewritten not to use file operations: on non-Unix systems sockets may not be files. This change allows, after some additional effort, to run FTP on windows. Thus FTP now runs natively on the Macintosh, runs on GNUstep on unix systems like BSD, Solaris or Linux and now on Windows too.

Second, the data connections are handled in a separate thread, which talks back to the main thread using DO (Distributed Objects). This allows the UI to remain responsive during list and download operations: this wasn't a real issue on the Macintosh, but on GNUstep windows wouldn't even redraw their contents during download, making the progress bar pretty useless. I still do not allow concurrent downloads, since the FTP protocol is not designed for that and it needs some workarounds.

Enjoy! Be sure to have the latest version of GNUstep base, since the DO system contains some fixes which are needed for FTP to work correctly.

The GNU Workspace

Thanks to the continuous improvement by the HURD team and thanks to a nice hacking evening with Matt Rice, quite some improvement was done on GNUstep with HURD. I was already able to have some rough results years ago, but then for a long time everything was unusably broken.

The only major thing to do was to set the global default NSPortIsMessagePort to NO.

In the screenshot we can see a GNU Workspace: done with GNUstep on GNU/Hurd.
GWorkspace is running, the upcoming FTP 0.2 can be seen too and it works well, meanign that distributed objects do work. Terminal.app works pretty fine as does the Rich text editor Ink. Not seen here, but ProjectCenter and Gorm do work too.

Cool is the front most application: Vespucci, the GAP browser which has at its core SimpleWebKit, runs too and loads an URL. This means that sockets, port, and rendering do work on Hurd well enough! Although still quite primitive, a browser on Hurd...

I have noticed some instabilities, with some applications starting up twice or closing and I suspect it is due to the applications not correctly registering with the daemons or with their ports dying.

Filing and refining

Few news here lately.
I have been busy looking and fixing several bugs inside FTP and GWorkspace, to make them ready for release. Today I was able to compile GWorkspace on Windows, a first after I updated the build system.
I collaborated also with Gregory and Fred to search and fix small bugs and issues withing base and gui, related to the applications mentioned above. So essentially, "polish" here and there and I would expect a release of the mentioned programs soon. Stay tuned.

FTP news: Threads and Windows

After a long silent hiatus, now some good news!

Development proceeded, but I did not announce anything since the code was too buggy. Two were the areas of change since the ancient 0.1 release: threads and socket core.

I want FTP to have a worker thread during file transfers, else the user interface is unresponsive, which is barely acceptable on the Macintosh and unusable on GNUstep, where there wasn't even a progress refresh. My first attempts called the gui from the worker threads which gave problems on GNUstep. Now with DO, the controller separation is need and works very well.

I rewrote the core data transfer mechanism, which previously was in typical BSD style where sockets where used as standard files, which a more portable recv() approach. Together with some tweaks and macros this means that socket operations work on Windows!

FTP is thus now able to work on windows too, I attach a screenshot.

Sunday Evening (AlemanniaStep)

Thus it came to an end, AlemanniaStep, that is. Thanks to a prepared schedule of topics, the short time was exploited well. We had an interesting demo of the development of various handheld devices by Nikolaus and we had some discussion about how to market ourselv better, how to improve the SoftwareIndex and our problems with packaging in distributions.

The rest was dedicated to hacking (as we see in the Picture, Fred fixing weird Font stuff that SWK triggered). Fred and I fixed the backend and Terminal bugs, Nikolaus hacked on SWK and I tested it on both Mac and GNUstep providing continuous feedback and it indeed improved.
Another session was dedicated to porting and checking of FlexiSheet, which we got finally compiling on the Mac, although with some compromises. Although not ready, it is foreseeable to adapt some pieces so it will run under GNUstep. Gerold found some issues with PCH on debian and made a good proposal in improving FTP after testing it.
These activities consumed quite some time, thus there was little time for windows. Also because one of the bugs didn't reproduce as expected.

I'll write about results in the next future, when they get a bit more finalized.

New releases for GAP

This weekend Battery Monitor 0.2 and FTP 0.1 were released for the GNUstep Application Project. I hope with this small contribution to help out a bit the GNUstep problem which is, in my opinion, also a general lack of tools and applications.

Battery Monitor checks ACPI and to do this peeks inside the /proc file system. Once again working with it makes me thing on how weak and bad the idea of files versus syscalls is. I am forced to parse files with a useless overhead. Furthermore linux did also a very poor standardization effort and the /proc/acpi changes from laptop to laptop as well as from kernel to kernel version!

Also I have a worried thought for the future, I spread myself thin over a couple of projects now, all of which I think are useful. As I fear to get more busy in the future and as I hit some problems in the current design of the applications, I seriously fear that without external help and collaboration the projects are going to stagnate and be left unfinished, which would be indeed a pity. But it once again reflects another aspect of the GNUstep community.

This also reminds me to tickle Nicola again about the possibility to use kaffe with JIGS! Java integration can only do good to us.
