Complete rework of package accessor logic
Hopefully we've finally arrived at package handling nirvana, or at least
this commit will get us a heck of a lot closer. The former method of getting
the depends list for a package was the following:
1. call alpm_pkg_get_depends()
2. this method would check if the package came from the cache
3. if so, ensure our cache level is correct, otherwise call db_load
4. finally return the depends list
Why did this suck? Because getting the depends list from the package
shouldn't care about whether the package was loaded from a file, from the
'package cache', or some other system which we can't even use because the
damn thing is so complicated. It should just return the depends list.
So what does this commit change? It adds a pointer to a struct of function
pointers to every package for all of these 'package operations' as I've
decided to call them (I know, sounds completely straightforward, right?). So
now when we call an alpm_pkg_get-* function, we don't do any of the cache
logic or anything else there- we let the actual backend handle it by
delegating all work to the method at pkg->ops->get_depends.
Now that be_package has achieved equal status with be_files, we can treat
packages from these completely different load points differently. We know a
package loaded from a zip file will have all of its fields populated, so
we can set up all its accessor functions to be direct accessors. On the
other hand, the packages loaded from the local and sync DBs are not always
fully-loaded, so their accessor functions are routed through the same logic
as before.
Net result? More code. However, this code now make it roughly 52 times
easier to open the door to something like a read-only tar.gz database
backend.
Are you still reading? I'm impressed. Looking at the patch will probably be
clearer than this long-winded explanation.

other hand, the packages loaded from the local and sync DBs are not always
fully-loaded, so their accessor functions are routed through the same logic
as before.
Net result? More code. However, this code now make it roughly 52 times
easier to open the door to something like a read-only tar.gz database
backend.
Are you still reading? I'm impressed. Looking at the patch will probably be
clearer than this long-winded explanation.

static const char *_cache_get_arch(alpm_pkg_t *pkg)
|
Complete rework of package accessor logic
Hopefully we've finally arrived at package handling nirvana, or at least
this commit will get us a heck of a lot closer. The former method of getting
the depends list for a package was the following:
1. call alpm_pkg_get_depends()
2. this method would check if the package came from the cache
3. if so, ensure our cache level is correct, otherwise call db_load
4. finally return the depends list
Why did this suck? Because getting the depends list from the package
shouldn't care about whether the package was loaded from a file, from the
'package cache', or some other system which we can't even use because the
damn thing is so complicated. It should just return the depends list.
So what does this commit change? It adds a pointer to a struct of function
pointers to every package for all of these 'package operations' as I've
decided to call them (I know, sounds completely straightforward, right?). So
now when we call an alpm_pkg_get-* function, we don't do any of the cache
logic or anything else there- we let the actual backend handle it by
delegating all work to the method at pkg->ops->get_depends.
Now that be_package has achieved equal status with be_files, we can treat
packages from these completely different load points differently. We know a
package loaded from a zip file will have all of its fields populated, so
we can set up all its accessor functions to be direct accessors. On the
other hand, the packages loaded from the local and sync DBs are not always
fully-loaded, so their accessor functions are routed through the same logic
as before.
Net result? More code. However, this code now make it roughly 52 times

So what does this commit change? It adds a pointer to a struct of function
pointers to every package for all of these 'package operations' as I've
decided to call them (I know, sounds completely straightforward, right?). So
now when we call an alpm_pkg_get-* function, we don't do any of the cache
logic or anything else there- we let the actual backend handle it by
delegating all work to the method at pkg->ops->get_depends.
Now that be_package has achieved equal status with be_files, we can treat
packages from these completely different load points differently. We know a
package loaded from a zip file will have all of its fields populated, so
we can set up all its accessor functions to be direct accessors. On the
other hand, the packages loaded from the local and sync DBs are not always
fully-loaded, so their accessor functions are routed through the same logic
as before.
Net result? More code. However, this code now make it roughly 52 times
easier to open the door to something like a read-only tar.gz database
backend.
Are you still reading? I'm impressed. Looking at the patch will probably be
clearer than this long-winded explanation.

the depends list for a package was the following:

Complete rework of package accessor logic
Hopefully we've finally arrived at package handling nirvana, or at least
this commit will get us a heck of a lot closer. The former method of getting
the depends list for a package was the following:
1. call alpm_pkg_get_depends()
2. this method would check if the package came from the cache
3. if so, ensure our cache level is correct, otherwise call db_load
4. finally return the depends list
Why did this suck? Because getting the depends list from the package
shouldn't care about whether the package was loaded from a file, from the
'package cache', or some other system which we can't even use because the
damn thing is so complicated. It should just return the depends list.
So what does this commit change? It adds a pointer to a struct of function
pointers to every package for all of these 'package operations' as I've
decided to call them (I know, sounds completely straightforward, right?). So
now when we call an alpm_pkg_get-* function, we don't do any of the cache
logic or anything else there- we let the actual backend handle it by
delegating all work to the method at pkg->ops->get_depends.
Now that be_package has achieved equal status with be_files, we can treat
packages from these completely different load points differently. We know a
package loaded from a zip file will have all of its fields populated, so
we can set up all its accessor functions to be direct accessors. On the
other hand, the packages loaded from the local and sync DBs are not always
fully-loaded, so their accessor functions are routed through the same logic
as before.
Net result? More code. However, this code now make it roughly 52 times
easier to open the door to something like a read-only tar.gz database
backend.
Are you still reading? I'm impressed. Looking at the patch will probably be
clearer than this long-winded explanation.

Complete rework of package accessor logic
Hopefully we've finally arrived at package handling nirvana, or at least
this commit will get us a heck of a lot closer. The former method of getting
the depends list for a package was the following:
1. call alpm_pkg_get_depends()
2. this method would check if the package came from the cache
3. if so, ensure our cache level is correct, otherwise call db_load
4. finally return the depends list
Why did this suck? Because getting the depends list from the package
shouldn't care about whether the package was loaded from a file, from the
'package cache', or some other system which we can't even use because the
damn thing is so complicated. It should just return the depends list.
So what does this commit change? It adds a pointer to a struct of function
pointers to every package for all of these 'package operations' as I've
decided to call them (I know, sounds completely straightforward, right?). So
now when we call an alpm_pkg_get-* function, we don't do any of the cache
logic or anything else there- we let the actual backend handle it by
delegating all work to the method at pkg->ops->get_depends.
Now that be_package has achieved equal status with be_files, we can treat
packages from these completely different load points differently. We know a
package loaded from a zip file will have all of its fields populated, so
we can set up all its accessor functions to be direct accessors. On the
other hand, the packages loaded from the local and sync DBs are not always
fully-loaded, so their accessor functions are routed through the same logic
as before.
Net result? More code. However, this code now make it roughly 52 times
easier to open the door to something like a read-only tar.gz database

where the filelist got doubled up because it was loaded twice.
Packages are originally loaded with INFRQ_BASE. In an upgrade/sync, the
package is checked for file conflicts next, leaving us in an "INFRQ_BASE |
INFRQ_FILES" state. Later, when committing a single package, we have an
explicit call to _alpm_local_db_read() with INFRQ_ALL as the level. Because
the package's level did not match this, we skipped over our previous "does
the incoming level match where I'm at" shortcut, and continued to load
things again, because of a lack of fine-grained checking for each of DESC,
FILES, and INSTALL.
The end result is we loaded the filelist twice, causing our remove logic to
iterate twice over the installed files, spewing a bunch of "cannot find file
X" messages.
Fix the problem by doing a bit more bitmasking logic throughout the load
method, and also fix the sanity check at the beginning of the function- this
should *only* be used for local packages as opposed to the "not a package"
check that was there before.
A debug log message was added to upgraderemove as well to match the one
already in the normal remove codepath.

Fix double filelist issue when upgrading a package
Due to the way we funk around with package data loading, we had a condition
where the filelist got doubled up because it was loaded twice.
Packages are originally loaded with INFRQ_BASE. In an upgrade/sync, the
package is checked for file conflicts next, leaving us in an "INFRQ_BASE |
INFRQ_FILES" state. Later, when committing a single package, we have an
explicit call to _alpm_local_db_read() with INFRQ_ALL as the level. Because
the package's level did not match this, we skipped over our previous "does
the incoming level match where I'm at" shortcut, and continued to load
things again, because of a lack of fine-grained checking for each of DESC,
FILES, and INSTALL.
The end result is we loaded the filelist twice, causing our remove logic to
iterate twice over the installed files, spewing a bunch of "cannot find file
X" messages.
Fix the problem by doing a bit more bitmasking logic throughout the load
method, and also fix the sanity check at the beginning of the function- this
should *only* be used for local packages as opposed to the "not a package"
check that was there before.
A debug log message was added to upgraderemove as well to match the one
already in the normal remove codepath.
