homespool configures directories that it seems
lp no longer usees. we can drop it.

dont' fall into the rathole.

again.

no spaces in our lists.
|
|
it doesn't help *that* much, and confuses the code.
|
|
bring it back.
|
|
It's not fatal for someone else to push a branch
with objects that we don't have. We should deal
with it gracefully, and act as though it doesn't
exist.
|
|
we would treat paths as relative, and not
step past leading '/'s, leading to an infinte
loop.

|
experiencing some issues with git9 transition... we likely need
to update git9 again before doing another attempt...
|
|
we were switching branches before we got the full list
of modified files, which could garble what we were trying
to merge.
|
|
merge1 would clobber the global '$base' variable,
which is not what we wanted. Run it in a subshell
with its own env.
|
|
|
|
we were catting $gitrel onto absolute paths. stop it.
|
|
after this update, we're on git: update sysupdate
to switch repositories.

In showlist, call bwindata instead of bwinopen in order to use a
pre-existing fd to write to the data file. This existing fd will
properly honour any address set by a previous write to the addr file.
Specifically, the redraw function sets addr to "," before calling
showlist in order to overwrite the entire contents of the window.
|
|
This is implemented by checking first if the uri is
a directory containing the .git/ subdirectory.
If this is the case, we fork git/serve serving the
repository on a pipe.
|
|
This makes it easier to serve local repositories where the sandboxing
gets in the way.
|
|
We checked if the file was changed from its parents.
If there were no parents, the answer was no, but it
should be yes.

We weren't giving all objects to the twixt() function, and
it was making bad life choices -- gambling, smoking, drinking,
and packing in too much data.
With more information, it doesn't do the last.
|
|
Sdvirtio supports multiple queues per device.
We only use one queue, but we shouldn't skip the
devices because of that.
|
|
|
|
|
|
We were execing a lot to copy the data -- do less of it.
|
|
Moving the mount point to within the repo
directory means that we can have multiple
git repos mounted at once with no conflict.

behaviour in a.out(6)
For 64-bit architectures, the a.out header has the HDR_MAGIC flag set
in the magic and is expanded by 8 bytes containing the 64-bit virtual
address of the programs entry point. While Exec.entry contains physical
address for kernel images.
Our sysexec() would always use Exec.entry, even for 64-bit a.out binaries,
which worked because PADDR(entry) == entry for userspace pointers.
This change fixes it, having the kernel use the 64-bit entry point
and document the behaviour in the manpage.

Forgot to add common.rc in the initial commit.

|
This struct member is available for any user of
the library, and is not part of our internal API.
It should be documented.

Add a snapshot of git9 to 9front.
|
|
|
|
Removed:
- Challenge reponse auth.
- Noworld login.
- Anonymous users writing files to /incoming.

|
it turns out that calculating physical address of pml4 is faster
than reading the machine register, so pass it explicitely.

The 9p debug server was broken as it assumed the first
tree file added would have a qid of 0 (it has a qid
of 1 as the root directory is using 0 already).
Instead, just compare File* pointers and get rid of
the table (less code).
When passing 64-bit unsigned addresses as 64-bit signed
file offsets, we have to make sure to not pass negative
offsets (filtered out by kernel and lib9p)!
This is solved by clearing and sign bit in encoding and
63-bit sign extension on decoding.
Make the mem file writable (needed for acid).
The 9p debug server provided a single directory containing
mem and regs files. This patch renames the regs file
(which is in vmx specific text format) to "xregs" and
adds "regs" and "kregs" file which use the same format
as exported by the kernels /proc filesystem.
This allows one to bind the vmx directory over a proc
directory and attach acid to a running system like:
mount -b /srv/vmx /proc/1
acid -k -lkernel 1 /sys/src/9/pc64/9pc64
