It looks like cached patches are truncated to the nearest 1024-byte
boundary in the patch body. E.g.:
> mricon@nikko:[/tmp]$ wget -O no-cache
> "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/?id=6e1b4fdad5157bb9e88777d525704aba24389bee"
...
> 2014-06-11 15:34:51 (80.4 MB/s) - ‘no-cache’ saved [4767]
Patch is complete, without truncation. Next hit, with cache in place:
> mricon@nikko:[/tmp]$ wget -O yes-cache
> "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/?id=6e1b4
> fdad5157bb9e88777d525704aba24389bee"
...
> 2014-06-11 15:35:01 (17.0 MB/s) - ‘yes-cache’ saved [4096/4096]
Length truncated to 4096. The cache on disk looks truncated as well, so
the bug must me during the process of saving cache. The same is true for
larger patches:
> mricon@nikko:[/tmp]$ wget -O no-cache
> "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/?id=2840c566e95599cd60c7143762ca8b49d9395050"

Since the "html" functions use raw write(2) to STDIO_FILENO, we don't
notice problems with most pages, but raw patches write using printf(3).
This is fine if we're outputting straight to stdout since the buffers
are flushed on exit, but we close the cache output before this, so the
cached output ends up being truncated.
Make sure the buffers are flushed when we finish outputting a patch so
that we avoid this.
No other UIs use printf(3) so we do not need to worry about them.
Actually, it's slightly more interesting than this... since we don't set
GIT_FLUSH, Git decides whether or not it will flush stdout after writing
each commit based on whether or not stdout points to a regular file (in
maybe_flush_or_die()).
Which means that when writing directly to the webserver, Git flushes
stdout for us, but when we redirect stdout to the cache it points to a
regular file so Git no longer flushes the output for us.
The patch is still correct, but perhaps the full explanation is
interesting!

Drop the context parameter from the following functions (and all static
helpers used by them) and use the global context instead:
* cgit_print_http_headers()
* cgit_print_docstart()
* cgit_print_pageheader()
Remove context parameter from all commands
Drop the context parameter from the following functions (and all static
helpers used by them) and use the global context instead:
* cgit_get_cmd()
* All cgit command functions.
* cgit_clone_info()
* cgit_clone_objects()
* cgit_clone_head()
* cgit_print_plain()
* cgit_show_stats()
In initialization routines, use the global context variable instead of
passing a pointer around locally.
Remove callback data parameter for cache slots
This is no longer needed since the context is always read from the
global context variable.

Instead of using our own formatting, use log_tree_commit() from Git to

Move filepair_cb() from ui-patch.c to ui-shared.c and rename it to
filepair_cb_raw(). This callback will be used in ui-diff.c in a
follow-up patch.
Note that it is not straightforward to extract filepair_cb() from
ui-diff.c which is why it is not done here as well.

This removes many uses of "fmt" which uses a fixed size static pool of
fixed size buffers. Instead of relying on these, we now pass around
argument lists for as long as possible before using a strbuf to render
content of an arbitrary size.

While doing this, remove declarations from header files where the
corresponding definition is declared "static" in order to avoid build
errors.
Also re-order existing headers in ui-*.c so that the file-specific
header always comes immediately after "cgit.h", helping with future
consistency.

We already have a global cgit_version which is set from the #define'd

Copying the output of cgit and using it in patches now works when adding
files to or removing files from the repository. This is helpful for people
who use cgit in their patch workflow.
The new ctx.qry.ignorews variable is passed via cgit_diff_files() and
cgit_diff_tree() to Git's diff machinery. This is equivalent to passing
--ignore-all-space to 'git diff'.

All html-functions can be quite easily separated from the rest of cgit, so
