No need to scan the entire string, but prefer to match git
behavior. This might be faster if/when Perl can create
substrings efficiently using CoW.
Fix a 80-column violation while we're at it.

Eventually, we'll have special displays for various git objects
(commit, tree, tag). But for now, we'll just use git-show
to spew whatever comes from git.

Not entirely sure what is causing this, but it appears to
be causing infinite loops when attempting to display certain
blobs.
Fortunately, the fair scheduling of public-inbox-httpd prevented
this from becoming a real problem aside from increasing CPU
usage.

We were relying on Danga::Socket using the "bytes" pragma,
previously. Nowadays, the "bytes" pragma is not recommended in
general, but bytes::length remains acceptable for getting the
byte-size of a scalar.
|
|
We want to be able to take advantage of this in other modules
|
|
It turns out there's no point in having multiple instances of
this or having to worry about destruction or destruction
ordering.
This will make it easier to reuse the one instance we have
across different modules.

Favor in-place utf8::decode since it's a bit faster without
method dispatch overhead; and don't care about validity just
yet.
HlMod->do_hl itself should return "utf8" strings, since other
parts of our code can use it, so it's not the job of ViewVCS to
post-process HlMod output.
|
|
Only to be pedantic...
|

|
|
This will become critical for future changes to display
git commits, diffs, and trees.
Use "qspawn.wcb" instead of "qspawn.response" to enhance
readability.

Forking off git-cat-file here for streaming large blobs is
reasonably efficient, at least no worse than using
git-http-backend for serving clones. So let our limiter
framework deal with it.
git itself isn't great for large files, and AFAIK there's no
stable/widely-available mechanisms for reading smaller chunks
of giant blobs in git itself.
Tested with some giant GPU headers in the Linux kernel.

Proper ordering of destruction seems required to avoid segfaults
at shutdown.
|
|
We need to post-process "highlight" output to ensure it doesn't
contain odd bytes which cause "wide character" warnings or
require odd glyphs in source form.
|
|
And update 216dark.css to match a color scheme I'm used to;
which is fairly minimal and doesn't use all the classes
"highlight" provides.
|
|
SolverGit::ERR already writes the exception to the debug
log before calling {user_cb}, so there's no need for viewvcs
to append it.
|

The psgi_qx routine in the now-abandoned "repobrowse" branch
allows us to break down blob-solving at each process execution
point. It reuses the Qspawn facility for git-http-backend(1),
allowing us to limit parallel subprocesses independently of Perl
worker count.
This is actually a 2-3% slower a fully-synchronous execution;
but it is fair to other clients as it won't monopolize the server
for hundreds of milliseconds (or even seconds) at a time.

We need to keep line-numbers from <a> tags synced to the actual
line numbers in the code when working in smaller viewports.
Maybe I only work on reasonable projects, but excessively
long lines seem to be less of a problem in code than they are
in emails.

As with our use of the trailing slash in $MESSAGE_ID/T/ and
'$MESSAGE_ID/t/' endpoints, this for 'wget -r --mirror'
compatibility as well as allowing sysadmins to quickly stand up
a static directory with "index.html" in it to reduce load.

Meaningful names in URLs are nice, and it can make
life easier for supporting syntax-highlighting
