[PipelineManager::] Pipeline Manager.
|
|
|
|
Claiming and creating copies of the pipeline genre: used for pipelines of
|
|
code-generation stages.
|
|
|
|
@h Genre definition.
|
|
The |pipeline_genre| can be summarised as follows. Copies consist of single
|
|
files. These are recognised by having the filename extension |.interpipeline|.
|
|
They are stored in nests, in |N/Pipelines/Title-vVersion.i7x|. Their build
|
|
graphs are single vertices with no build or use edges.
|
|
|

|
|
void PipelineManager::start(void) {
|
|
pipeline_genre = Genres::new(I"pipeline", TRUE);
|
|
METHOD_ADD(pipeline_genre, GENRE_WRITE_WORK_MTID, PipelineManager::write_work);
|
|
METHOD_ADD(pipeline_genre, GENRE_CLAIM_AS_COPY_MTID, PipelineManager::claim_as_copy);
|
|
METHOD_ADD(pipeline_genre, GENRE_SEARCH_NEST_FOR_MTID, PipelineManager::search_nest_for);
|
|
METHOD_ADD(pipeline_genre, GENRE_COPY_TO_NEST_MTID, PipelineManager::copy_to_nest);
|
|
}
|

|
void PipelineManager::write_work(inbuild_genre *gen, OUTPUT_STREAM, inbuild_work *work) {
|
|
WRITE("%S", work->title);
|
|
}
|
|
|
|
@ Pipelines live in their namesake subdirectory of a nest:
|
|
|
|
=
|
|
pathname *PipelineManager::path_within_nest(inbuild_nest *N) {
|
|
if (N == NULL) internal_error("no nest");
|
|
return Pathnames::down(N->location, I"Pipelines");
|
|
}
|
|
|
|
@ Pipeline copies are annotated with a structure called an |inform_pipeline|,
|
|
which stores data about pipelines used by the Inform compiler.
|
|
|
|
=
|
|
inform_pipeline *PipelineManager::from_copy(inbuild_copy *C) {
|
|
if ((C) && (C->edition->work->genre == pipeline_genre)) {
|
|
return RETRIEVE_POINTER_inform_pipeline(C->metadata);
|
|
}
|
|
return NULL;
|
|
}
|
|
|
|
inbuild_copy *PipelineManager::new_copy(inbuild_edition *edition, filename *F) {
|
|
inbuild_copy *C = Copies::new_in_file(edition, F);
|
|
Pipelines::scan(C);
|
|
return C;
|
|
}
|
|
|
|
@h Claiming.
|
|
Here |arg| is a textual form of a filename or pathname, such as may have been
|
|
supplied at the command line; |ext| is a substring of it, and is its extension
|
|
(e.g., |jpg| if |arg| is |Geraniums.jpg|), or is empty if there isn't one;
|
|
|directory_status| is true if we know for some reason that this is a directory
|
|
not a file, false if we know the reverse, and otherwise not applicable.
|
|
|
|
An pipeline, for us, simply needs to be a file with extension |.interpipeline|.
|
|
|
|

|
|
void PipelineManager::claim_as_copy(inbuild_genre *gen, inbuild_copy **C,
|
|
text_stream *arg, text_stream *ext, int directory_status) {

@h Searching.
|
|
Here we look through a nest to find all pipelines matching the supplied
|
|
requirements.
|
|
|
|
=
|
|
void PipelineManager::search_nest_for(inbuild_genre *gen, inbuild_nest *N,
|
|
inbuild_requirement *req, linked_list *search_results) {
|
|
if ((req->work->genre) && (req->work->genre != pipeline_genre)) return;
|
|
pathname *P = PipelineManager::path_within_nest(N);
|
|
scan_directory *D = Directories::open(P);
|
|

|
filename *F = Filenames::in(P, LEAFNAME);
|

inbuild_copy *C = PipelineManager::claim_file_as_copy(F, NULL);
|
|
if ((C) && (Requirements::meets(C->edition, req))) {

@h Copying.
|
|
Now the task is to copy a pipeline into place in a nest. This is easy,
|
|
since a pipeline is a single file; to sync, we just overwrite.
|
|
|
|

|
filename *PipelineManager::filename_in_nest(inbuild_nest *N, inbuild_edition *E) {

Editions::write_canonical_leaf(leaf, E);
|
|
WRITE_TO(leaf, ".interpipeline");
|
|
filename *F = Filenames::in(PipelineManager::path_within_nest(N), leaf);
|
|
DISCARD_TEXT(leaf)
|
|
return F;
|
|
}
|
|
|
|
void PipelineManager::copy_to_nest(inbuild_genre *gen, inbuild_copy *C, inbuild_nest *N,
|
|
int syncing, build_methodology *meth) {
|
|
filename *F = PipelineManager::filename_in_nest(N, C->edition);
|
|
|
|
if (TextFiles::exists(F)) {
|
|
if (syncing == FALSE) { Copies::overwrite_error(C, N); return; }
|
|
} else {
|
|
if (meth->methodology == DRY_RUN_METHODOLOGY) {
|
|
TEMPORARY_TEXT(command)
|
|
WRITE_TO(command, "mkdir -p ");
|
|
Shell::quote_path(command, Filenames::up(F));
|
|
WRITE_TO(STDOUT, "%S\n", command);
|
|
DISCARD_TEXT(command)
|
|
} else {
|

Pathnames::create_in_file_system(N->location);
|

Pathnames::create_in_file_system(Filenames::up(F));
|

}
|

}

TEMPORARY_TEXT(command)
|

WRITE_TO(command, "cp -f ");

Shell::quote_file(command, C->location_if_file);

Shell::quote_file(command, F);
