f98dcbf1d6 Kernel: Respect the process umask in open() and mkdir(). 2019-02-22 02:39:13 +01:00

6d3e12899b Kernel: Pass process arguments directly on the stack. 
Get rid of the convoluted get_arguments and get_environment syscalls.
This patch also adds a simple /bin/env that just prints its environment.

920e8e58ed Kernel+Userland: Implement setuid() and setgid() and add /bin/su 
Also show setuid and setgid bits in "ls -l" output. :^)

8b64f213a1 Kernel: sigpending() and sigprocmask() should validate memory writes. 2019-02-21 21:33:52 +01:00

19acb2baf7 Kernel: Add file permission checks to link() syscall. 
Also use the new name, not the old name, for the new link, duh.

f0a869ea50 Kernel: Process::cwd_inode() should return a reference. 
There's always a current working directory inode.

ce3b548077 Kernel: Separate VFS stat() from open(). 
It was very confusing that you had to open a FileDescriptor in order to stat
a file. This patch gives VFS a separate stat() function and uses it to
implement the stat() and lstat() syscalls.

f5f136931a Kernel: Start adding various file system permission checks. 
Fail with EACCES in various situations. Fix userland bugs that were exposed.

43075e5878 Add a simple /bin/df which gathers its info from /proc/df. 2019-02-21 14:48:00 +01:00
Andreas Kling
7d288aafb2 Kernel: Add link() syscall to create hard links. 
This accidentally grew into a little bit of VFS cleanup as well.

Also add a simple /bin/ln implementation to exercise it.

b6115ee5b7 WindowServer: Choose resizing direction based on where it's initiated. 
Divide the window into 3x3 hot areas and resize in the direction of the
corner where the resize starts. The middle is a no-op area.

This needs some polish but the basic mechanism is good.

16cd4585cd WindowServer: Oops, forgot to plumb through the base size for incresize. 2019-02-21 10:11:12 +01:00

6084cd0c56 Add concept of size increments to windowing system. 
Use this to implement incremental resizing for Terminal so that we only
ever resize to fit a perfect number of rows and columns.

This is very nice. :^)

fd575055c2 Userland: /bin/sh shouldn't crash on EINTR. 2019-02-20 23:45:00 +01:00

0aaec6b19a Support resizing the Terminal app. 
I set it up so that TIOCSWINSZ on a master PTY gets forwarded to the slave.
This feels intuitively right. Terminal can then use that to inform the shell
or whoever is inside the slave that the window size has changed.

TIOCSWINSZ also triggers the generation of a SIGWINCH signal. :^)

0ca3112301 FileManager: Fix glitch in the alternating directory item backgrounds. 2019-02-20 22:10:28 +01:00

fa02d2a39b Rework the rendering model so that clients instantiate backing stores. 
This makes interactive resizing work a lot better, althought it's still not
perfect. There are still glitches and unpleasant flashes of zeroed memory.

e0b81ee4c9 Ext2FS: Remove the inode cache lock in favor of one big lock instead. 2019-02-20 21:58:55 +01:00

266e77259e Kernel: If someone else zero-fills a shared VMO page, don't freak out. 
Just map the new page and move on.

6158f456fa Kernel: Don't remove from SharedBuffer map while iterating it. 
This was causing a finalizer crash when handling a process that co-owned
multiple shared buffers.

d054fbee91 WindowServer: Don't spam clients with resize events. 
Wait for them to finish a paint, then send them a new resize event.
The exception is when releasing the mouse button to end the resize.
Then we send a new resize event right away.

59b8183c4b WindowServer: Support resizing windows. 
This is pretty limited and not entirely stable, but it does work! :^)

9763eb44f9 LibGUI: Pack toolbar buttons closer together. 2019-02-20 11:56:28 +01:00
Andreas Kling
bf30502560 LibGUI: Implement enter/leave events (with WindowServer support.) 
Windows now learn when the mouse cursor leaves or enters them.
Use this to implement GWidget::{enter,leave}_event() and use that
to implement the CoolBar button effect. :^)
 2019-02-20 10:12:19 +01:00
Andreas Kling
af7eb5c89c Launcher: Let's use CoolBar style buttons in here for now. 
This will be helpful for testing the hover events.

Andreas Kling
d353c7c3d6 LibGUI: Support different button styles. 
I want to try an MS Office 97 "CoolBar" inspired look for my toolbars.
This is only the painting support, we still need hover events to implement
the actual effect.

dc753b58a5 LibGUI: Improve GBoxLayout so it can better support GToolBar. 
Added spacing and margin concepts to GLayout. Support layout a sequence
of nothing but fixed-size objects in the desired orientation. :^)
 2019-02-20 09:04:28 +01:00
Andreas Kling
b704d3d295 LibGUI: Add a GToolBar class that can be populated with GActions. 
The same action can be added to both a menu and a toolbar.
Use this to put a toolbar into FileManager. This is pretty neat. :^)

57546d8420 WindowServer: Only invalidate the menubar rect when switching menubars. 2019-02-19 16:32:06 +01:00
Andreas Kling
b561a5976f WindowServer: Correct invalidation rects for menu windows. 2019-02-19 15:46:48 +01:00
Andreas Kling
98784ad3cb WindowServer: Avoid overdraw by shattering dirty rects into unique shards. 
The algorithm I came up with is O(n^2) but given the small numbers of rects
we're typically working with, it doesn't really matter. May need to revisit
this in the future if we find ourselves with a huge number of rects.

9b71307d49 WindowServer: Support windows with alpha channels. And per-WSWindow opacity. 
This patch also adds a Format concept to GraphicsBitmap. For now there are
only two formats: RGB32 and RGBA32. Windows with alpha channel have their
backing stores created in the RGBA32 format.

Use this to make Terminal windows semi-transparent for that comfy rice look.
There is one problem here, in that window compositing overdraw incurs
multiple passes of blending of the same pixels. This leads to a mismatch in
opacity which is obviously not good. I will work on this in a later patch.

The alpha blending is currently straight C++. It should be relatively easy
to optimize this using SSE instructions.

For now I'm just happy with the cute effect. :^)
