#201: Use « olena » instead of « oln » as an identifier ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: defect | Status: new Priority: major | Milestone: Component: Olena | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- We should no longer use « `oln` » ; « `olena` » is much more clearer. * The Subversion repository is called `oln`, because `olena` was already used (arg!); we should not do this mistake again: the future Git repository shall be named `olena`. * Likewise, Olena's build farm URL (https://buildfarm.lrde.org/buildfarm/oln/) should be renamed to `olena`. If you find some other places where the project is called `oln` instead of `olena`, please report them here. TIA. -- Ticket URL: <https://trac.lrde.org/olena/ticket/201> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #126: Speed up tests

#126: Speed up tests -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: major | Milestone: Olena 1.0ß Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- Some tests take a very long time to execute. Main causes are: * input image(s) are too big [[BR]] => they should be reduced (sometimes, testing on `lena.pgm` is just too costly); * the default, non-optimized compilation settings (`-O0 -ggdb`) produces very inefficient code for certain algorithms [[BR]] => we should locally increase the level of optimization (e.g., `-O1` or `-O2`) for these tests, and '''document''' this in `Makefile.am` (explain why we made changes in `CXXFLAGS` for a given test). We might want to make a list of lengthy tests here before solving this ticket. -- Ticket URL: <https://trac.lrde.org/olena/ticket/126> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.

[Olena] #214: Use Automake 1.11's AM_DEFAULT_SOURCE_EXT

#214: Use Automake 1.11's AM_DEFAULT_SOURCE_EXT -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: minor | Milestone: Component: Milena | Version: 1.0 Keywords: Make | -------------------------+-------------------------------------------------- Quoting the [http://www.mail-archive.com/automake@gnu.org/msg15022.html announce of Automake 1.11]: {{{ - The default source file extension (.c) can be overridden with AM_DEFAULT_SOURCE_EXT now. }}} Which allows us to replace {{{ bin_PROGRAMS = foo bar baz foo_SOURCES = foo.cc bar_SOURCES = bar.cc baz_SOURCES = baz.cc }}} with {{{ bin_PROGRAMS = foo bar baz AM_DEFAULT_SOURCE_EXT = .cc }}} (Of course, « `AM_DEFAULT_SOURCE_EXT = .cc` » should be factored in some `common.mk` file.) This just rocks if you consider the tons of `*_SOURCES` lines in the zillions of `tests/*/Makefile.am` files. On the downward side, this change requires Automake 1.11, which is not even in Debian unstable as of July 24, 2009. We might want to wait a little bit before requiring this version. -- Ticket URL: <https://trac.lrde.org/olena/ticket/214> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #207: Use Automake 1.11

#207: Use Automake 1.11 -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: enhancement | Status: new Priority: major | Milestone: Olena 1.1 Component: Olena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- Automake 1.11 provides a better framework for tests: each test can generate a log file, and the test suite is a mere rule generating a summary log, depending on all these logs. The `check` rule is no longer based on a shell `for` loop, and `make` can truly honors its `-j` (parallel instances) option when testing. Of course, one need to be careful with side effects, notably files created by tests, as one test may overwrite the output(s) of another tests. Akim recommends that test `foo` writes its outputs to `foo.dir`. Moreover, this permits many improvements: * One can generate pretty-printed versions of the tests using, e.g., `rst2html` (if the log contains an RST output) on the logs. * One can have a `recheck` rule reruning only the failed tests, since the first line of the log records the outcome of the test (pass or fail). * Also, provided dependencies are well set, this can probably help one write rules to rerun only the needed tests when a change occurred in the source tree (but I don't know yet how to do this). -- Ticket URL: <https://trac.lrde.org/olena/ticket/207> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #129: Reintegrate oln.m4 (full or a part of it) into Olena 1.0

#129: Reintegrate oln.m4 (full or a part of it) into Olena 1.0 -----------------------------------+---------------------------------------- Reporter: levill_r | Owner: levill_r Type: enhancement | Status: new Priority: minor | Milestone: Olena 1.0ß Component: Olena | Version: 1.0 Keywords: configure autoconf M4 | -----------------------------------+---------------------------------------- In Olena 0.11, `oln.m4` (which might be renamed to `olena.m4`) provided useful services to both the Olena package (search for libraries, set up flags for tests, etc.) and autoconfiscated packages using Olena, by providing a `--with-oln` (to be renamed to `--with-olena`) flag. We should reintegrate a part of these features, possibly in two M4 macro packages: * one for Olena, * one for Olena-based projects. -- Ticket URL: <https://trac.lrde.org/olena/ticket/129> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.
