In the commandTest the HRN_STORAGE_REMOVE replacement uses .errorOnMissing when the code being tested added the file. The reason for this is 3 fold:
1. to ensure that an inadvertent typo in the path/file name does not go undetected,
2. to ensure that nothing else has removed the file prior to the call, and
3. consistency
Also, added "stanza" to comment when a stanza stop file is removed vs an "all" stop file.
Multi-part upload may fail despite returning an HTTP success code. Check for the ETag field in the result and if not present consider the upload to have failed. This will trigger a retry at the local job level.
Links were followed before they were checked for validity so a circular link would send the manifest build into endless recursion leading to a crash. Fix by moving the recursion after the link check.
Note that this issue has existed since the C migration and was not introduced by the refactor in eba013b.
Data directory creation was added during the C migration, but creation of the base data directory (PGDATA) was prevented by a check migrated from Perl.
Remove the check and update tests to create the data directory at least once.
Includes archiveCommon, archiveGet and archivePush.
Also fixed a test that was looking in repo instead of repo3 in the original archivePush to use the repo3 path as stated by the comment (line 879 in original tests and line 855 in new tests).
It seems better to use TEST_PATH in combination with a constant string rather than have a number of different path constants. This improves readability and reduces confusion about which constant should be used.
For tests already updated as part of the macro-replacement effort, the output tests (TEST_ERROR, TEST_RESULT_LOG, TEST_STORAGE_LIST and TEST_RESULT_STR) have been simplified for readability to remove all but the TEST_PATH constants. The ongoing macro-replacement effort will include these changes.
Updated: expireTest, stanzaTest, checkTest, infoTest, verifyTest (infoArchive and infoBackup had no changes).
Switch from JSON-based to binary protocol for communicating with local and remote process. The pack type is used to implement the binary protocol.
There are a number advantages:
* The pack type is more compact than JSON and are more efficient to render/parse.
* Packs are more strictly typed than JSON.
* Each protocol message is written entirely within ProtocolServer/ProtocolClient so is less likely to get interrupted by an error and leave the protocol in a bad state.
* There is no limit on message size. Previously this was limited by buffer size without a custom implementation, as was done for read/writing files.
Some cruft from the Perl days was removed, specifically allowing NULL messages and stack traces. This is no longer possible in C.
There is room for improvement here, in particular locking down the allowed sequence of protocol messages and building a state machine to enforce it. This will be useful for resetting the protocol when it gets in a bad state.
Some tests had to be reordered or updated, as follows:
* Reordered tests at line 317 and 331 to avoid unnecessary file removal.
* Change "stanza found" test at line 1735 to reflect real-life scenario. Originally this test had the cipher-pass environment key set up which caused the RepoGrp to be 2 but with no valid repo path. This resulted in the repo loops executing for the repo2 but since the path was not defined, the tests just reported "none" for cipher which is incorrect since the repo IS encrypted.
* Moved order of HRN_CFG_LOAD in some tests when able to avoid using storageTest.
It is better to clear errors after the catch block completes rather than leave them set until the next error. This also make is possible to tell when a error is currently being handled, which a function further down the stack might use to modify its behavior. Currently this is only useful in testing, but clearing the error seems like a good idea in general.
Two places used errors outside the CATCH() block. Mem context cleanup now uses a FINALLY() which is a better implementation anyway. The error handling in main() now calls exitSafe() from withing the CATCH() block.
Add StringList, which is not a primitive type but rather an array of String types.
Also update pckWriteToLog() to work after pckWriteEnd(), i.e. this->tagStackTop is NULL.
Move a PackRead or PackWrite object to a new mem context.
Also note that these functions may not work as expected with pack objects created by pckReadNewBuf() and pckWriteNewBuf() since the pack object does not have ownership of the passed buffer and cannot move it.
The hrnErrorThrowP() macro allows errors with specified fields to be generated, which simplifies testing.
Update the common/exit test to use the new macro.
Azurite, which is used for testing, did not enforce this before so the capital letters were not a problem. Now Azurite enforces the same rules as Azure so use lower-case identifiers instead.
These names were only used in integration tests so there was no production impact.
This allows TEST_STORAGE_EXISTS() to be used in most cases where TEST_STORAGE_REMOVE() was used before.
Rename TEST_STORAGE_REMOVE() to HRN_STORAGE_REMOVE() now that is is no longer used as a test. Still allow an error when the file is missing just to help keep tests tidy.
Since the pack type was stored in 4 bits, only 15 values were allowed (0 was reserved).
Allow virtually unlimited types by storing type info in a base-128 encoded integer following the tag when the type bits in the tag are set to 0xF.
Also separate the type IDs used in the pack (PackTypeMap) from those presented to the user (PackType). The prior PackType enum exposed implementation details to the user, e.g. pckTypeUnknown.
The functions were named with short integer representations (e.g. I32) but the param structs were using longer ones, e.g. UInt32. Shorten the integer representations in the param structs to match.
Also rename pckReadUInt64Internal() to pckReadU64Internal() for the same reason.
The pg storage must be started before the repo storage to set the max remotes allowed to 2. The protocol helper expects all remotes to have the same type so we are cheating here a bit, but without this ordering the second remote will never be sent an explicit exit and may not save coverage data.
At one time there was a lot more in this header but it got merged with the enums and constants in config.auto.c, leaving only the ConfigOptionType enum.
Auto-generating the ConfigOptionType enum is not very useful since new option types require code in parse.c.

HRN_CFG_LOAD() handles the majority of test configuration loads and has various options for special cases.
It was not clear when to use harnessCfgLoadRaw() vs harnessCfgLoad(). Now "raw" functionality is granular and enabled by parameters, e.g. noStd.
