git used to track cache size in object
count, rather than bytes. This had the
unfortunate effect of making memory use
depend on the size of objects -- repos
with lots of large objects could cause
out of memory deaths.
now, we track sizes in bytes, which should
keep our memory usage flatter.
Untangle the lexer and interpreter thread state.
Fix the file and line number error reporting, getting rid of
Xsrcfile instruction, as the whole code block can only come
from a single file, stuff the source file in slot[1] of the
code block instead.
Remove limitations for globber (path element limits)
and be more intelligent about handling globbing by
inserting Xglob instruction only when needed and not
run it over every Xsimple argument list.
Remove fragile ndot magic and make it explicit by adding
the -q flag to . builtin command.
Add -b flag for full compilation.
Make exitnext() smart, so we can speculate thru rcmain and
avoid the fork().
Get rid of all print(2) format functions and use io
instead.
Improve the io library, adding rstr() to handle tokenization,
which allows us to look ahead in the already read buffer
for the terminators, avoiding alot of string copies.
Auto indent pcmd(), to make line number reporting more usefull.
Implement here documents properly, so they can work everywhere.
We seem to have a botch in the protocol negotiation, where
we leak some protocol packets into the packfile; this will
need to be fixed before we put this change in.
The initial working directory of a new window may be set by a
`-cd directory` option. However, the `-cd directory` option is
not capable of handling paths with spaces when used via wctl.
To enable paths with spaces the function
/sys/src/cmd/rio/wctl.c:/^parsewctl is extended to handle quoted
directory paths.
Before applying the patch the following will fail to open a new
window by writing to /dev/wctl:
<snip>
% rio -i window
% mkdir '/tmp/path with space'
% echo new -cd '''/tmp/path with space''' window -x rc >> /dev/wctl
% pwd
/tmp/path with space
<snap>
The following invocation fails as well:
<snip>
% window -cd '/tmp/path with space'
% pwd
/tmp/path with space
<snap>
After applying the patch the above sequences work as expected,
opening a window running rc with the working directory set to
'/tmp/path with space'.
SSL is implemented by devssl. It's extremely
obsolete by now, and is not used anywhere but
cpu, import, and oexportfs.
This change strips out the devssl bits, but
does not (yet) remove the code from libsec.
If we don’t explicitly check for ‘h’ in troff, we can’t reliably check
for non-htmlroff well.
Consider the following:
.if h \{\
. de M
. tm m
..\}
Without this change, this will print m and not define macro M.
the pack cache was very stupid: it would close packs
as early as possible, which would prevent packs from
getting reused effectively. It would also select a
bad pack to close.
This picks the oldest pack, refcounts correctly, and
keeps up to Npackcache open at once (though it will
go over if more are in use).
This makes vmap()/vunmap() take a vlong size argument,
and change the type of Pci.mem[].size to vlong as well.
Even if vmap() wont support large mappings, it is nice to
get the original unruncated value for error checking.
pc64 needs a bigger VMAP window, as system76 pangolin
puts the framebuffer at a physical address > 512GB.
