This is actually a fully functional build except: * All internal shared libraries are static linked to make sure there is no interference with ports (and to reduce build time). * It does not have the python/perl/etc plugin or API support. * By default, it installs as "svnlite" rather than "svn". * If WITH_SVN added in make.conf, you get "svn". * If WITHOUT_SVNLITE is in make.conf, this is completely disabled. To be absolutely clear, this is not intended for any use other than checking out freebsd source and committing, like we once did with cvs. It should be usable for small scale local repositories that don't need the python/perl plugin architecture.

* apr_vformatter() is a generic printf-style formatting routine
|
|

* @param flush_func The function to call when the buffer is full
|
|
* @param c The buffer to write to
|
|
* @param fmt The format string
|
|
* @param ap The arguments to use to fill out the format string.
|
|
*
|
|
* @remark
|
|
* <PRE>
|
|
* The extensions are:
|
|
*
|
|
* %%pA takes a struct in_addr *, and prints it as a.b.c.d
|
|
* %%pI takes an apr_sockaddr_t * and prints it as a.b.c.d:port or
|
|
* [ipv6-address]:port
|
|
* %%pT takes an apr_os_thread_t * and prints it in decimal
|
|
* ('0' is printed if !APR_HAS_THREADS)
|
|
* %%pt takes an apr_os_thread_t * and prints it in hexadecimal
|
|
* ('0' is printed if !APR_HAS_THREADS)
|
|
* %%pm takes an apr_status_t * and prints the appropriate error
|
|
* string (from apr_strerror) corresponding to that error code.
|
|
* %%pp takes a void * and outputs it in hex
|
|
* %%pB takes a apr_uint32_t * as bytes and outputs it's apr_strfsize
|
|
* %%pF same as above, but takes a apr_off_t *
|
|
* %%pS same as above, but takes a apr_size_t *
|
|
*
|
|
* %%pA, %%pI, %%pT, %%pp are available from APR 1.0.0 onwards (and in 0.9.x).
|
|
* %%pt is only available from APR 1.2.0 onwards.
|
|
* %%pm, %%pB, %%pF and %%pS are only available from APR 1.3.0 onwards.
|
|
*
|
|
* The %%p hacks are to force gcc's printf warning code to skip
|
|
* over a pointer argument without complaining. This does
|
|
* mean that the ANSI-style %%p (output a void * in hex format) won't
|
|
* work as expected at all, but that seems to be a fair trade-off
|
|
* for the increased robustness of having printf-warnings work.
|
|
*
|
|
* Additionally, apr_vformatter allows for arbitrary output methods
|
|
* using the apr_vformatter_buff and flush_func.
|
|
*
|
|
* The apr_vformatter_buff has two elements curpos and endpos.
|
|
* curpos is where apr_vformatter will write the next byte of output.
|
|
* It proceeds writing output to curpos, and updating curpos, until
|
|
* either the end of output is reached, or curpos == endpos (i.e. the
|
|
* buffer is full).
|
|
*
|
|
* If the end of output is reached, apr_vformatter returns the
|
|
* number of bytes written.
|
|
*
|
|
* When the buffer is full, the flush_func is called. The flush_func
|
|
* can return -1 to indicate that no further output should be attempted,
|
|
* and apr_vformatter will return immediately with -1. Otherwise
|
|
* the flush_func should flush the buffer in whatever manner is
|
|
* appropriate, re apr_pool_t nitialize curpos and endpos, and return 0.
|
|
*
|
|
* Note that flush_func is only invoked as a result of attempting to
|
|
* write another byte at curpos when curpos >= endpos. So for
|
|
* example, it's possible when the output exactly matches the buffer
|
|
* space available that curpos == endpos will be true when
|
|
* apr_vformatter returns.
|
|
*
|
|
* apr_vformatter does not call out to any other code, it is entirely
|
|
* self-contained. This allows the callers to do things which are
|
|
* otherwise "unsafe". For example, apr_psprintf uses the "scratch"
|
|
* space at the unallocated end of a block, and doesn't actually
|
|
* complete the allocation until apr_vformatter returns. apr_psprintf
|
|
* would be completely broken if apr_vformatter were to call anything
|
|
* that used this same pool. Similarly http_bprintf() uses the "scratch"
|
|
* space at the end of its output buffer, and doesn't actually note
|
|
* that the space is in use until it either has to flush the buffer
|
|
* or until apr_vformatter returns.
|
|
* </PRE>
