ee83b1bcf4 LibCore: Use URL in CHttpRequest 
Now there's just CHttpRequest::set_url(URL), no need to specify the
host, port and path manually anymore.

Updated ChanViewer and Downloader for the API change.

ed43770b2f AK: Add a basic URL class to help us handle URL's 
We're gonna need these as we start to write more networking programs.

afd25679bc GJsonArrayModel: Support fields that aren't tied to a single JSON value 
Change the custom data massaging callback to take a const JsonObject&.
This will allow binding together data from multiple fields into one
output in the model. :^)

a4548a150f Kernel: Hack the default keymap to support UK pipe/backslash 
Since this key number doesn't appear to collide with anything on the
US keymap, I was thinking we could get away with supporting a hybrid
US/UK keymap. :^)

078ce97c41 GJsonArrayModel: Add an optional "massage_for_display" fieldspec hook 
This allows to you install a custom callback that can do anything with
Role::Display data before it's returned by GJsonArrayModel::data().

0f0a528323 ProcessManager: Remove SocketModel and NetworkAdapterModel 
These are trivially replaced by GJsonArrayModels :^)

6e50631e35 LibGUI: Add GJsonArrayModel, a simple JSON-data-file-as-GModel helper 
This makes it very easy to expose JSON files as GModels. :^)

79f867238a printf: Support dynamic fill widths 
The printf formatting mini-language actually allows you
to pass a '*' character in place of the fill width specification,
in which case it eats one of the passed in arguments and uses it
as width, so implement that.

cfe8fdd5aa LibM: Implement sqrt() 
Use the x87 fsqrt instruction for that.

We cannot use __builtin_sqrt(), since GCC expands it into
a sqrt() call, so we just loop endlessly.

instead, as you would expect.

d31ddf9aaa Painter: Fix off-by-one in bounding rects for right-aligned text 
Another instance of "Rect::right() is the last pixel *inside* the rect,
not the first pixel outside the rect" messing me up.

2c947a2c97 ProcessManager: Enable automatic column sizing for all table views 
Start making use of the neat new mode in GTableView.
 2019-08-09 19:32:09 +02:00
Andreas Kling
b5525d4ec3 GTableView: Add a mode for automatically sizing column to fit content 
You can now call GTableView::set_size_columns_to_fit_content(true) and
the table columns will grow to fit the content. They will never shrink,
only grow.

This means I can spend a lot less time fidgeting with column widths :^)

84a54c7cf7 ProcFS: Make a new nifty /proc/net directory 
And move /proc/netadapters and /proc/net_tcp there. Now they're
/proc/net/adapters and /proc/net/tcp respectively, with more to come ^)

7e309e27dd Kernel: Clean up and sanitize incoming packet handling a bit more 
Once we've converted from an Ethernet frame to an IPv4 packet, we can
pass the IPv4Packet around instead of the EthernetFrameHeader.

Also add some more code to ignore invalid-looking packets.
 2019-08-09 10:42:01 +02:00
Andreas Kling
f9de264f88 Kernel: Actually, let's not hang() on bad incoming packets 
That kinda defeats the purpose of being smart enough to ignore them :^)

Andreas Kling
9e2a00248e Kernel: Do some basic sanity checking on IPv4 packet headers 
Ignore packets that are too small, or not as large as they claim to be.

04603237da Kernel: Merge FooSocketHandle classes into a single SocketHandle<Foo> 
- IPv4SocketHandle => SocketHandle<IPv4Socket>
- TCPSocketHandle => SocketHandle<TCPSocket>
- UDPSocketHandle => SocketHandle<UDPSocket>

Andreas Kling
d6bce37756 ProcessManager: Add a "Network" tab with live adapter and socket stats 
This fetches info from /proc/netadapters and /proc/net_tcp, updating
every second. Very cool. :^)

899366da9d GTableView: Debug-log the current column width while resizing 
This makes it easier to decide on a good initial width for a column.

eb3c19773e ProcessManager: Tweak memory stats widget layout to fit more text 
After a while, the kmalloc/kfree counts got too wide for the label.

865a1b913c AK: Add Optional<T>(const U&) 
This replaces Optional<T>(U&&) which clang-tidy complained may hide the
regular copy and move constructors. That's a good point, clang-tidy,
and I appreciate you pointing that out!

318068fe1b Kernel: Turns global Custody and Inode tables into InlineLinkedLists 
Yet more of this same thing. Each one of these patches has a small but
noticeable impact on the steady-state kmalloc numbers. :^)

Andreas Kling
07425580a8 Kernel: Put all Regions on InlineLinkedLists (separated by user/kernel) 
Remove the global hash tables and replace them with InlineLinkedLists.
This significantly reduces the kernel heap pressure from doing many
small mmap()'s.

Andreas Kling
a96d76fd90 Kernel: Put all VMObjects in an InlineLinkedList instead of a HashTable 
Using a HashTable to track "all instances of Foo" is only useful if we
actually need to look up entries by some kind of index. And since they
are HashTable (not HashMap), the pointer *is* the index.

Since we have the pointer, we can just use it directly. Duh.
This increase sizeof(VMObject) by two pointers, but removes a global
table that had an entry for every VMObject, where the cost was higher.
It also avoids all the general hash tabling business when creating or
destroying VMObjects. Generally we should do more of this. :^)
