Detailed Description

Paralelized compression example:

cr_CompressionTask *task_1, *task_2;
GThreadPool *pool;

// Prepare tasks
task_1 = cr_compressiontask_new("foo", "foo.gz", CR_CW_GZ_COMPRESSION, 1,
                                CR_CHECKSUM_SHA256, NULL);
task_2 = cr_compressiontask_new("bar", "bar.gz", CR_CW_GZ_COMPRESSION, 1,
                                CR_CHECKSUM_SHA512, NULL);

// Create pool for tasks
pool = g_thread_pool_new(cr_compressing_thread, NULL, 2, FALSE, NULL);

// Push tasks to the pool
g_thread_pool_push(pool, task_1, NULL);
g_thread_pool_push(pool, task_2, NULL);

// Wait until both treats finish and free the pool.
g_thread_pool_free(pool, FALSE, TRUE);

// Use results
// Do whatever you want or need to do

// Clean up
cr_compressiontask_free(task_1, NULL);
cr_compressiontask_free(task_2, NULL);

Function Documentation

void cr_compressing_thread	(	gpointer	data,
		gpointer	user_data
	)

Function for GThreadPool.

void cr_compressiontask_free	(	cr_CompressionTask *	task,
		GError **	err
	)

Frees cr_CompressionTask and all its components.

Parameters

task	cr_CompressionTask task
err	GError **

cr_CompressionTask* cr_compressiontask_new	(	const char *	src,
		const char *	dst,
		cr_CompressionType	compression_type,
		cr_ChecksumType	checksum_type,
		int	delsrc,
		GError **	err
	)

Function to prepare a new cr_CompressionTask.

Parameters

src	Source filename.
dst	Destination filename or NULL (then src+compression suffix will be used).
compression_type	Type of compression to use.
checksum_type	Checksum type for stat calculation. Note: Stat is always use. If you don't need a stats use CR_CHECKSUM_UNKNOWN, then no checksum calculation will be performed, only size would be calculated. Don't be afraid, size calculation has almost no overhead.
delsrc	Delete src after successuful compression. 0 = Do not delete, delete otherwise
err	GError **. Note: This is a GError for the cr_compresiontask_new function. The GError that will be at created cr_CompressionTask is different.

Returns

New cr_CompressionTask.

void cr_repomd_record_fill_thread	(	gpointer	data,
		gpointer	user_data
	)

Function for GThread Pool.

void cr_repomdrecordfilltask_free	(	cr_RepomdRecordFillTask *	task,
		GError **	err
	)

Frees cr_RepomdRecordFillTask

cr_RepomdRecordFillTask* cr_repomdrecordfilltask_new	(	cr_RepomdRecord *	record,
		cr_ChecksumType	checksum_type,
		GError **	err
	)

Function to prepare a new cr_RepomdRecordFillTask.

Parameters

record	cr_RepomdRecord.
checksum_type	Type of checksum.
err	GError **

Returns

New cr_RepomdRecordFillTask.
