Avoid calling libtool to link every single test case, by building just one binary from all the sources. This binary is then given the task of choosing tests to run (based on user selection and individual test requirement), forking each test into its own process and accumulating the results.

|
|
* 2004-11-04 Ned Konz <ned@squeakland.org>
|
|
*
|
|
* Reported bug on mailing list:
|
|
*
|
|
* From: Ned Konz <ned@squeakland.org>
|
|
* To: cairo@cairographics.org
|
|
* Date: Thu, 4 Nov 2004 09:49:38 -0800
|
|
* Subject: [cairo] getting assertions [cairo_cache.c:143: _entry_destroy:
|
|
* Assertion `cache->used_memory > entry->memory' failed]
|
|
*
|
|
* The attached program dies on me with the assert
|
|
*
|
|
* $ ./testCairo
|
|
* testCairo: cairo_cache.c:143: _entry_destroy: Assertion `cache->used_memory > entry->memory' failed.
|
|
*
|
|
* 2004-11-04 Carl Worth <cworth@cworth.org>
|
|
*
|
|
* I trimmed down Ned's example to the folllowing test while still
|
|
* maintaining the assertion.
|
|
*
|
|
* Oh, actually, it looks like I may have triggered something
|
|
* slightly different:
|
|
*
|
|
* text_cache_crash: cairo_cache.c:422: _cairo_cache_lookup: Assertion `cache->max_memory >= (cache->used_memory + new_entry->memory)' failed.
|
|
*
|
|
* I'll have to go back and try the original test after I fix this.
|
|
*
|
|
* 2004-11-13 Carl Worth <cworth@cworth.org>
|
|
*
|
|
* Found the bug. cairo_gstate_select_font was noticing when the
|
|
* same font was selected twice in a row and was erroneously failing
|
|
* to free the old reference. Committed a fix and verified it also
|
|
* fixed the original test case.
